Cyber ​​security and data management are closely linked. This is why many agencies are refining their strategies for collecting and managing large stores or network lakes and other data in the service of better cybersecurity. For ways to tackle the cyber data problem, the Federal Drive with Tom Temin spoke with R Street Institute’s senior cybersecurity and emerging threats researcher Bryson Bort.

Tom Temin: Since this data lake-like technology or any type of mass storage in the cloud is available, do agencies run the danger of collecting too much data, so that it becomes difficult to identify and sift through? the needles you are actually looking for in the haystack.

Bryson Bort: Yeah, I call it the NSA problem. We collect all we can. And then you have the challenge of, with all you’ve got and as it builds up, is it easy for me to answer the questions I want to ask about this data? Part of the challenge, of course, is that I’m not always sure what question I want to ask before I go through it. And therefore a structuring that helps you get there more quickly. But that’s not always realistic. Things change. We have different things that we have learned from the data itself. But yeah, that first part is we start making some really big haystacks. And, Tom, here’s the worst part: you talk about finding a needle in a haystack. The worst part is sometimes you are looking through the haystack. And there is no needle to find.

Tom Temin: Yes, that could be a lot of spinning wheels and hourglasses of death I guess as you try to wait for a response to come out. And what is the best practice, first of all, for the architecture of a data lake today? I don’t think anyone wants to invest in the kind of storage hardware infrastructure they might have in the 80s, 90s, and 2000s.

Bryson Bort: Yes, so first of all, the concept of a data lake is possible because of the more cross-platform accessibility we get with the cloud. I don’t just have to connect to a particular server somewhere to access a client server, approach to retrieve this file. Rather, it is me who accesses the large crater in which I have filled all the data like a lake, hence the term data lake. So what are some of these challenges? First, it’s the same problem we’ve had since the 1980s: configuration management. What do I have? What is that? How to categorize it? How to maintain its status? There is a status, there is version management. That gets into the problem, so if I don’t have the ability to just maintain that status, I have duplication issues. And I am having problems with the current data. I’m looking at two same things that are different, which one is first? And so I am not confused by the story. Being able to assess this current infrastructure – what structure seems best suited to this? So in terms of configuration management, the challenges, we’re doing it on something that already exists. There is a big beast of different data in different forms in different silos. And of course, there is no common Rosetta Stone to be able to understand all of this, and even what exists. And so a typical approach is usually program-based – sometimes it can be department-based – where you’re going to go in and you’re going to try to encapsulate as much as possible, even recognizing that you’re not going to have it all. grabbed and establish that process. So we go back there, we find the things that are already there. And we set up the process to identify the new things that are going to be created, so that we fill the lake. And then maintaining the water quality, I guess, is our analogy here for this data in this lake.

Tom Temin: Now, you can swim in a lake and you can’t swim in a haystack. So maybe that’s an advantage.

Bryson Bort: We’re mixing metaphors here, just like real data issues.

Tom Temin: Pretty much, because the data is generated by network sensors, your different types of traffic control: routers and switches, etc. But let’s also say that for the purpose of detecting fraud, which could be a clue of cybersecurity, you have transaction data from systems deployed to the public or other agencies. And so you have many, many different data formats from many different database programs. Or maybe it’s not database programs, or just data discarded during the operation of a piece of equipment. What’s the current best practice to streamline this, so that the data is searchable, from all of these different sources?

Bryson Bort: So when I think of streamlined, I think of what we can cut, and that’s always a challenge. No one ever wants to not have the data. The background is data retention: how long do we keep particular data? And there are liability issues that can be related to this. So it’s not quite a question, both of rationalization and of standardization. How do I take disparate datasets that have different types – not everything simple, like it’s just digital? Some things are temporal, some things are geophysical, and there may be others. So how do I put them all in one common place where they can work and interact with each other? Data sources – so where do I have visibility, what is driving the data? Because when you spoke of network devices, you spoke of databases. But there is also the human aspect, people specifically generate data. There are other devices. Just throwing, like, comments on things like the [DoD Joint Artificial Intelligence Center]; we’re going to have machine learning and artificial intelligence that’s dependent on data from a training set perspective and some level of integrity. And the potential bias in that is going to affect that. But it will also create its own data accordingly, as a result of these operations. So with the data, it starts with what are my sources? What is my visibility on my sources? What is the understanding of these sources, versus the questions I want to ask – what are these missions – and then my ability to standardize and centralize this data for analysis and use?

Tom Temin: Okay, and does that then involve a process of removing some of the formatting? What about some of the metadata around the data and accessing things that are then much more interoperable?

Bryson Bort: Yeah, I mean, so there’s a filter there to put it in a particular format that’s part of that normalization.

Tom Temin: And we mentioned the idea that it’s hard to find a needle in a haystack, if there is a needle in the first place. And there is an element of time in discovering and mitigating cybersecurity. And even for things that have a long lifespan, which they sometimes don’t. So how do you quickly analyze a data lake? What are some of the technologies or techniques for sorting large amounts of data in such a way as to react quickly to what might happen?

Bryson Bort: It is therefore a correlation. The data itself, think of it as singular atoms. And what I want to be able to do is apply structured queries or unstructured queries in different ways that match questions I already know or want to ask. These structures are where I identified a pattern. This and that together will always answer that question for me. In simple security terms, let’s just look in terms of threat hunting, if I see this particular host activity related to this host activity related to this network traffic, it’s a common attack chain for this type of Chinese spy campaign. And so I don’t want to keep asking myself this question; I identified this idea, which becomes a regular query now where the data with that query will now trigger an alert. So let’s get human intervention, the data does the job for us based on what we can see in the visibility to bring about the human interaction or the human interaction, to now go into the detection, response and correction of this. that we now know is a breach. Then there are the unstructured queries. So the questions that I don’t know yet. As we want to look at and identify an example, again using the security example. So I have this structured set. But what are the variables around this that I might start to look at? What are some things like, well, if the traffic is coming from that particular location, or if I identified that the round trip on that traffic, that’s actually how we could have identified SolarWinds? SolarWinds has been in the news a lot. The traffic for SolarWinds had to come back to someone, that someone was not in this country. And so the TTL on the round trip of the packet was actually longer than it should have been. And that’s the kind of thing that this data can give you that rich information where you don’t need to know it was three obscured bounce jumps through the internet to get to Moscow. I just know, the first thing looks good. But that data made you question that because there is a pattern out there that would have revealed it.

BY WINSTONE ANTONIO

A recently launched strategic POULTRY network aims to promote new players in broiler chicken production across the country.

National Hatch Web (NHW) was created by Hatch Solutions, Victors Chickens, Vet Sol and Provincial Partner Breeders.

NHW President Victor Kwaramba said their ultimate goal was to address long-standing limitations and shortcomings in the current structure of the poultry industry coupled with severe deficits that have been overlooked over the years.

“Periodic shortages, distribution and accessibility of day-old chicks in parts of Zimbabwe, market dominance by a few players as well as inadequate financial support at critical points in the value chain require gasoline. of the NHW initiative, ”he said.

Kwaramba said that while poultry production seemed to be most people’s favorite business stream, there were no emerging brands.

“We have explored our limitations and realized the strength that lies within us as partnerships. With collective efforts and contributions for a common goal to have a positive impact on the poultry sector, ”he said.

“Through the NHW initiative, there will be increased participation and productivity, job creation and protection of new players in broiler chick production in Zimbabwe. “

He said the structure of NHW would promote efficient distribution and the participation of new players through financial and technical support.

“We develop and protect our members while creating a sustainable system that touches local and international markets,” Kwaramba said.

“Currently, we are inviting all players in the value chain, from primary grain producers such as corn and soybeans, feed manufacturers, chick producers, veterinary suppliers, broiler breeders and manufacturers of hatching machines to retail outlets for meat products scattered across the country. to join National Hatch Web.

Kwaramba said farmers could join NHW at different levels.

“We can be part of our initiative as a primary producer of grains, namely corn and soybeans that will be used to make animal feed,” he said.

“We also need what we call provincial breeding partners, who will be responsible for producing fertilized broiler eggs, hatching them for a supply of day-old chicks,” he said. declared.

“This is the most powerful collective producer setup to achieve sustainable growth, productivity, and competitive advantage against unfair competition and the marketplace. “

Kwaramba said they are helping those who want to set up commercial hatcheries.

“We have forged a number of strategic partnerships with people like to achieve our goal of being the largest collective poultry producer in the county by 2023,” he said.

The Taliban have seized an unprecedented amount of American and Western weapons, representing a significant expansion of the organization’s military and combat capabilities. For more than two decades, the United States has provided the Afghan national defense and security forces with more than $ 20 billion in arms, materiel and equipment. However, the United States failed to produce a durable and effective Afghan army. As seen in recent weeks, most of the Afghan security forces withdrew from their positions and bases without a single shot being fired during the rapid advance of the Taliban, leaving behind large quantities of weapons supplied by the United States. Although the exact figures are not publicly known, estimates indicate that the Taliban are now in possession of around 300,000 infantry weapons, including M16A4 rifles, M240 machine guns and M4 rifles; 160,000 communications equipment; 16,000 night vision goggles; 2,000 armored vehicles, including M117 armored security vehicles, MaxxPro anti-mine vehicles and Humvees; and finally up to 40 aircraft, potentially including UH-60 Blackhawks, MD-530 helicopters, ScanEagle drones and A-29 Super Tucano light attack aircraft. The Taliban are now better equipped in terms of weapons than the Islamic State in Iraq and Syria (ISIS) was when the Iraqi army began its withdrawal from Mosul in 2014. In this situation, the Iraqi army supplied by the United States fled a much smaller group. militants, leaving behind thousands of small arms and armored vehicles, which the Islamic State quickly used.

One of the most immediate concerns is how the Taliban will use less sophisticated weapons such as night vision goggles and captured infantry weapons, mortars and artillery pieces. The Taliban now have a qualitative advantage over any resistance group that might regroup in the country, such as those in the historically anti-Taliban stronghold of the Panjshir Valley, northeast of Kabul. However, US officials fear that the Taliban’s possession of US military equipment could have other negative implications, both within and beyond Afghanistan’s borders. Unlike conventional armed forces, the Taliban does not have a clear top-down command structure. Much of it is structured horizontally and functions as a network of militias and fronts led by military commanders. Although in order to function within the Taliban, the militias must be recognized by the Board of Directors and not act against it, their commanders still have an extraordinary degree of autonomy. It has become a guiding principle of the Taliban leadership to grant its commanders a significant degree of autonomy, including day-to-day decision-making, in order to avoid divisions and a cumbersome administration. This command structure makes it entirely possible for equipment seized from the Afghan security forces to be diverted and sold to different militant groups and not be kept for use within the organization as a whole. In addition, to obtain additional income, the Taliban may be inclined to sell their newly acquired weapons to hostile actors and on the black market. Taliban partner militant organizations such as the Haqqani Network have the capacity to smuggle weapons out of Afghanistan and into the Middle East, Africa and even Southeast Asia. The Taliban may transfer military-grade communications equipment, US-made small arms and night vision goggles to non-state actors such as al-Qaeda, threatening the security of US and allied security forces and undermining regional stability.

But luckily for the United States, much of the Taliban’s new stockpile of military vehicles requires fairly sophisticated maintenance requirements and is unlikely to remain combat-ready in the long term. The Afghan army relied heavily on maintenance and technical support from American and foreign contractors. For example, the entire Afghan Army UH-1 Blackhawks fleet was maintained by foreign contractors. However, for the nascent arsenal of armored vehicles of the Taliban, the Islamist organization has such a quantity of them that it becomes possible to cannibalize the spare parts of some vehicles to operate others.

As the Office of Personnel Management continues its journey of IT modernization, it relies on a familiar and proven playbook.

Guy Cavallo has been with OPM for about 11 months, first as senior deputy director of information, then acting director of the agency’s IT in March. He got permanent job last month.

Now he’s building on the lessons he learned in the Small Business Administration, from moving to the cloud and adopting cybersecurity tools to retraining the IT workforce.

“I’m leading a big push to the cloud like I’ve done in my other two agencies,” he said. “I have an almost predefined 90-day approach on how to move an agency to the cloud in 90 days. I did it at the Transportation Security Administration. I did this SBA. Now I have refined it at OPM.

“We have established a cloud community of excellence,” he added. “We did our 90 day sprint. We have our initial architecture. We have our broadband connections in place. We are starting to activate cybersecurity tools in the cloud.

OPM still has several large legacy applications and mainframes, and its cybersecurity architecture to date is primarily on-premises. But Cavallo said OPM is gradually embracing more cloud-based cybersecurity tools, with the ultimate goal of running a mix of the two.

Ultimately, he wants to reduce the number of tools in OPM’s cybersecurity structure and make better use of the tools already in place.

“If I buy something, I try to use 100% of it, instead of buying five things and using 20% ​​of each and having that overlap,” Cavallo said. “There are a lot of tools in use at OPM today and I think we will be better off by reducing the footprint. “

This general philosophy also applies to Cavallo’s approach to training and developing OPM’s IT staff. Listening sessions with OCIO employees prompted him to look for more free online training sessions for IT staff.

“Not only at OPM, but I’ve heard this from other CIOs as well, there’s a strong belief that you have haves and have-nots,” Cavallo said. “You had favorite CIOs that could take training, and it could be $ 5,000 to $ 10,000 training. They could go and everyone would be told that there was no money for training.

OPM has a corporate agreement with Microsoft. Cavallo said it has leveraged this deal and signed up for Microsoft’s enterprise skills initiative, which allows it to offer online training to every OCIO employee.

“It immediately leveled the playing field,” he said. “All the big cloud providers are doing it. There are many free, high-quality training available today from major vendors. “

He also instructed OCIO employees, from administrative assistants to contract managers, to complete a two-hour introduction to the cloud classroom.

“I want everyone to know what we’re talking about. I was happy to see people step in and do that, ”he said.

Where the cloud is a central part of an employee’s job, Cavallo said his office would reimburse staff for taking and passing certification exams. As a result, more people are getting cloud certifications than ever before, he said.

“I need my legacy workforce,” Cavallo said. “I can’t just tell everyone to go and put it all in the cloud when I’m running final mainframe code that can be decades old. The best thing is to train them enough so that I can pair them with a cloud specialist, and we can re-platform this app or rewrite it with the legacy knowledge and also the latest technological knowledge.

Cavallo will also rely on another point of its IT modernization manual: playing nicely with the CFO.

“What I’ve learned throughout my career is that if the CIO doesn’t have a strong partnership with the CFO, you’re in trouble. The CFO controls your money. Something that I have always done is build this partnership. One of the first things I try to do is say, “On my current budget, if I can cut my own spending on investing in the cloud, will you let me keep the money? If you have a bad relationship with your CFO, you will lose that money and they will suffer the cuts.

However, this approach will not cover all of OPM’s IT modernization needs, especially as the administration develops new cybersecurity requirements for agencies every month or so.

To help OPM better comply with the terms of the recent cyber decree, for example, Cavallo said he had two pending applications with the Technology Modernization Fund Board, which would help OPM adopt cloud and zero trust solutions.

The agencies submitted just under 100 proposals for a share of the billion-dollar Technology Modernization Fund.

And to help OPM secure additional funding for IT modernization, Cavallo draws on another set of lessons he learned during his time at SBA.

The Biden administration is pushing Congress to establish new IT working capital, one of many recommendations the National Academy of Public Administration made earlier this spring in its report on improving the agency.

According to the proposal, OPM could transfer up to 3% of unspent salaries and expenses into working capital for IT modernization efforts.

So far, only the SBA has been able to secure congressional approval for its own IT working capital.

“We definitely took the language that we approved at the SBA, and reused it for OPM and said, ‘Hey you already approved this once, let’s do it again,’” Cavallo said.

A seven-bill minibus, which cleared the House at the end of last month, allows the OPM to create its own IT working capital in fiscal year 2022. The Senate has yet to weigh in on this matter , let alone presented a full set of 2022 appropriation bills.

Leading tech companies look to advance 6G in the new district

WEST LAFAYETTE, Ind. – The Purdue Research Foundation and Purdue University announced Tuesday, August 24, the launch of the “Lab to Life” (L2L) digital innovation platform in the Discovery Park District adjacent to the university campus. The launch is the next step in creating one of the most connected innovation communities in the country through the evolution from 5G to 6G.

“6G will move from one domain to a foundation to many vertical domains, from one network to a heterogeneous network of networks. From dynamic sharing and new spectra to cutting-edge intelligence and open architecture, 6G research must be accelerated through deployment in the United States, ”said Mung Chiang, Purdue executive vice president for strategic initiatives and Dean John A. Edwardson of the College of Engineering. “This group of leading industry partners and their leaders will transform the Discovery Park District of Purdue into the nation’s first large-scale 6G deployment area and, along with other essentials such as learning and the arts, will create a connected work-live-game community. “

L2L leverages the unique governance structure and open, neutral technology infrastructure deployed across the district’s more than 400 acres to advance the development of next-generation wireless networks and digital applications.

Earlier this year, PRF announced partnerships with neutral host infrastructure provider Tilson to deploy over 15 miles of high capacity fiber, emanating from an edge data center, and with SBA Communications for the deployment of CBRS networks. private throughout the district. Over the next decade, this community infrastructure will provide products and services to the approximately 20,000 people who will live, work, learn and visit the district.

“Our vision has been to provide not only one of the most connected communities in the United States for residents, employers and visitors to the neighborhood,” said David Broecker, Director of Innovation and Collaboration for PRF . “We also wanted to create an innovation community with a set of capabilities and assets to advance digital solutions in collaboration with leading technology companies and industrial partners. “

To support these efforts, PRF and Purdue formed the Technology Leaders Advisory Board (TLAB) made up of leading technology companies to advise on the further construction of networks and infrastructure in a way that maintains the open nature of the platform. to support future deployment. networks and applications. Member companies include AT&T, Celona, ​​Cisco, Dell, Ericsson, Intel, SBA Communications and Tilson.

“Over time, we want to expand this group to include others,” said Troy Hege, PRF vice president for technology and innovation. “The combination of being adjacent to the Purdue campus and advancing innovation by leveraging the district’s infrastructure platform provides the perfect environment for testing and evaluating next-generation technology solutions. “

Later this fall, a competition for cutting edge innovations ready for deployment will be held. Universities and companies will be invited to propose technologies that they wish to deploy either in infrastructure or in 5G, WiFi6 and 6G applications.

About Discovery Park District

The Discovery Park District is a 400-acre, billion-plus community adjacent to campus that will include labs, state-of-the-art manufacturing facilities, offices, retail stores, restaurants, housing, green spaces, trails and an airport with 7,000-foot track. The neighborhood, which is a designated opportunity area, is home to the Convergence Center for Innovation and Collaboration, a facility designed to serve as a “gateway” for companies looking to collaborate with Purdue.

Emma Okonji

THISDAY Newspapers has launched a WhatsApp edition to provide the digital PDF copy of its newspapers to over 73 million MTN subscribers for free download on the MTN Zigi Chatbot.

THISDAY and ARISE NEWS chairman / editor-in-chief Prince Nduka Obaigbena, who announced the launch yesterday, said it will take effect from today.

According to Obaigbena, “The WhatsApp edition is part of a series of business collaborations between THISDAY and MTN Nigeria, in fulfillment of a pledge made by THISDAY to MTN Nigeria, to commemorate the celebration of MTN’s 20th anniversary.

MTN, which rolled out its telecommunications services to Nigeria in August 2001, has maintained its original ownership structure and brand name since then, a development that has helped the MTN brand to focus more on expanding the market. network across the country, while providing quality service to its more than 73 million subscribers, with a market share of 39.3 percent.

Since its creation, MTN has maintained its position as the leading telecom operator in Nigeria in terms of the volume of subscribers on its network.

Launched last year, the MTN Zigi Chatbot is the telecommunications company’s new digital personal assistant that can answer questions and help subscribers with products, services and activations.

Zigi is chatting in English and is available to chat with existing MTN customers and non-MTN customers as a guest.

The Zigi chatbot saves time for customers who wait for the customer service representative to answer a question.

The online assistant chatbot was designed to enhance customers’ digital interactions with the brand and provide fast and secure marketing, sales and technical support.

Customers could interact with the chatbot on multiple channels including WhatsApp, Facebook Messenger, Telegram, MTN official website, and myMTN app.

Commenting on “Zigi”, MTN Nigeria Customer Relations Manager Ugonwa Nwoye said, “Zigi provides personalized, intuitive and prompt service to our customers. Its introduction will not take away the client’s access to live agents, but will serve as the first point of contact for clients who choose to interact with Zigi. ‘

“We believe that ‘Zigi’ will provide increased convenience which will translate into better experiences for our customers, which is at the heart of our goal as a company.”

For his part, MTN Nigeria’s digital director, Srinivas Rao, said “Zigi” will always align with MTN’s digital transformation goals.

“We now live in a fast-paced digital age with new technological advancements driving an ever-changing landscape. This is why at MTN, we are determined to lead the digital transformation, which will provide easy-to-use connectivity solutions, improve the customer experience and maintain the best quality of service for everyone in our ecosystem, ”said Rao.

With THISDAY’s offer, the 73 million MTN subscribers would have daily access to free downloads of THISDAY digital PDF copies. They would be able to read authoritative news in business, politics, health, environment, sports and in-depth interviews and analysis.

Giving details on MTN’s journey since 2001, MTN Board Chairman Dr Ernest Ndukwe said: The amount of revenue generated.

“We see the multiplier effect that connectivity services can have on the social and economic ecosystem. And now more than ever, I am optimistic about what the future holds for Nigeria’s digital economy and look forward to building it together, with all of you.

In his commentary, MTN Nigeria CEO Mr. Karl Toriola said: “This 20-year journey is the result of the limitless possibilities of our country, the incredible potential of Nigeria’s telecommunications and technology sector, and the advice and support we have received from millions of Nigerians, in all corners of the country.

Taliban special forces provide “security” at Kabul airport https://scotsbeavers.org/taliban-special-forces-provide-security-at-kabul-airport/ https://scotsbeavers.org/taliban-special-forces-provide-security-at-kabul-airport/#respond Sun, 22 Aug 2021 19:36:14 +0000 https://scotsbeavers.org/taliban-special-forces-provide-security-at-kabul-airport/ Taliban social media accounts say the Badri 313 outfit is parked at Kabul airport.

Taliban social media accounts say the Badri 313 outfit is parked at Kabul airport.

Taliban-linked social media accounts claim that members of the group’s Badri 313 team are providing “security” at Kabul International Airport. Badri 313 is a special forces wing of the Taliban army. He was responsible for some of the group’s key battlefield successes and also conducted complex “martyrdom” (suicide) operations.

Photos posted on Taliban-associated streams allegedly show Badri 313 units in and around Kabul airport. We don’t know how many men from the group are there. FDD Long War Diary did not independently confirm their presence.

The Haqqani Network, which plays an essential role in the political and military command structure of the Taliban, has long publicized the operations carried out by its special forces in the “Badri army”. The Haqqanis are, at a minimum, closely allied with al-Qaeda.

In February 2020, for example, Haqqani’s Manba Al Jihad media branch released a video titled “Badri Strike”. The production went live just weeks before the Trump administration struck a withdrawal deal with the Taliban in Doha.

“Badri Strike” contains excerpts from President Trump saying that “the American people are weary of war without victory”. Trump continued, “Nowhere is this more evident than with the war in Afghanistan, the longest war in American history, 17 years.” The producers of the video say America and its allies in Kabul have been defeated.

The narrator of the video states that while the United States once declared the Taliban to be “terrorists,” it was forced to negotiate with the jihadists. The talks are described as a clear victory for the Islamic Taliban Emirate, which the narrator presents as an example for other Muslim groups around the world. The production also places the imminent return of the Islamic Emirate from the Taliban in the context of the Muslims’ quest to restore an Islamic Caliphate to power. In other words, the Taliban anticipated a complete victory in the months to come.

Ustadh Mohammad Yasir, as seen in “Badri Strike”, a video posted by the Haqqani Network in February 2020.

A key ideologue featured in “Badri Strike” is Ustadh Mohammad Yasir, a figure in the Taliban-Al-Qaeda double hat. Yasir is said to have died in 2012 under somewhat murky circumstances. He had been arrested by Pakistani forces several years earlier. Yasir was a key ideologue for Al Qaeda’s recruiting efforts in Afghanistan and Pakistan.

Yasir has appeared in Al Qaeda media, most notably in an interview with As Sahab. Ayman al-Zawahiri paid tribute to Yasir in a speech published on the 18th anniversary of the September 11 attacks. Zawahiri recounted a meeting between Yasir and Bin Laden in the mountains of Tora Bora in late 2001, during which they discussed the 9/11 hijackings.

Yasir’s archival audio included in “Badri Strike” is therefore revealing. This shows that the Taliban’s special forces wing taps into the same ideological well as Al Qaeda. In the brief clip, Yasir explains the supposed virtues of martyrdom.

“It is the blessing of your sacrifices, your blood and your martyrs,” Yasir says in the clip included in “Badri Strike”. Yasir continues: “The martyrs of every nation are like candles. He burns himself, but brightens the darkness, he burns himself, but enlightens others. Likewise, if your martyrs sacrificed and burned their lives (for Allah SWT), they also illuminated the house of Islam.

Much of “Badri Strike” is devoted to glorifying the jihadist team responsible for the November 2018 attack on a G4S compound in Kabul. G4S is a UK security and intelligence company. “Badri Strike” documents the meticulous planning and training that led to the complicated suicide operation. A team of Badri 313 commandos had previously received elite training in small arms. They infiltrated the compound after one of their comrades detonated a large vehicle bomb outside.

Badri 313 is now providing security outside Kabul airport, according to Taliban sources online.

Social media sites associated with the Taliban shared this photo of the Badri 313 in Kabul.

Taliban special forces background

Members and supporters of the Taliban often use Badri 313 interchangeably with other terms to identify the group’s “special forces”. The infamous “red unit” or “blood unit” is also part of the organization’s commandos. The Taliban used these elite formations as shock troops in their conquest of Afghanistan. The name Badri 313 is a tribute to the battle of Badr, during which the prophet Muhammad is said to have led 313 men to victory.

The Haqqani Network promoted its special forces units as early as November 2011, when it carried out an attack on the Continental Hotel in Kabul. Haqqani’s video, titled “The Army of Badr 1,” featured “hot and engaging images of the training, wills and operations of the mujahedin who participated in this martyrdom search.” Manba al Jihad, the propaganda arm of the Haqqani Network, produced the video.

In 2015, the Taliban released another “Army of Badr” video of their Salahadin Ayyubi camp. The footage also celebrated the commandos who carried out a complex suicide bombing against the headquarters of the Afghan National Directorate of Security in Ghazni in September 2014.

One of Manba al Jihad’s most detailed videos of Taliban special forces was released in June 2020, just three months after the Trump administration agreed to a withdrawal agreement with the Taliban. Sirajuddin Haqqani gave a recorded speech praising the graduates of his Al Fateh military camp. Al Fateh camp is a well-known training location for the Taliban special forces. In the video titled “Victorious Forces (1)”, Siraj and Mullah Yacub, Mullah Omar’s son, praised the fighters, their commitment and military prowess, while stressing their importance to the Taliban jihad. Siraj and Yacub are both deputy emirs in the Taliban hierarchy. Two of the units featured in the June 2020 video showed Taliban fighters wearing the distinctive “Blood Unit” red headbands.

In early April 2021, just weeks before the Taliban launched their blitz to take over the country, the Taliban released dozens of images. The photos presented “[h]some of Mujahedin [holy warriors] and martyrdom seekers “who” graduated from the Khalid bin Waleed, Al-Fateh and Hazrat Abu Bakr Siddique military camps of the Islamic Emirate of Afghanistan. The footage showed well-armed Taliban fighters equipped with his special forces at various stages of training.

Al-Qaeda previously managed a unit in Afghanistan and Pakistan known as Brigade 313. This unit, which was part of the Lashkar Zil or Al-Qaeda’s Shadow Army, was led by the notorious jihadist Ilyas Kashmiri. Pakistani and military commander of Al Qaeda.

The United States killed Kashmir in a drone strike in South Waziristan in the spring of 2011. The 313 Brigade was made up of elements of the Afghan and Pakistani Taliban, as well as allied jihadist groups such as Laskhar-e- Jhangvi, Harakat-ul- Jihad-al-Islami, Lashkar-e-Taiba, Jaish-e-Mohammed, Jundallah and others. He formed the nucleus of what has become Al Qaeda in the Indian subcontinent. Kashmir had important ties with the Haqqani network. Before his death, he ran a training camp in Miramshah, North Waziristan, the Haqqani network’s base of operations in Pakistan.

Imagine if you could attach something to your skin without the need for glue. A biosensor, a watch, a communication device, a fashion accessory, the possibilities are endless. Thanks to a discovery at Binghamton University, State University of New York, that moment might be closer than you think.

Associate Professor Guy German and Zachary Lipsky, PhD ’21, recently published research in the journal Acta Biomaterialia which explores how human skin can control crack formation and why blood pressure monitors provide inaccurate results when measuring the mechanical properties of biological tissues.

Along the way, Lipsky developed a method to bind human skin to rubbery polymeric materials without an adhesive. Originally, a way to facilitate their experiments, he and German understood that they had made an important discovery.

“Zach came over one day and said, ‘Yeah, I did,'” German said. “I was like, ‘How the hell did you do that? Did you use any glue?’ Because we would also need to take into account the mechanical properties of the glue. And he said, “No, I just glued it.” We looked and we said, has that been done before? Never done, so we’re very happy on that side.

An invention disclosure for the art has been filed which could lead to a patent on what he calls “a very simple technique” that could revolutionize biotechnology.

“I didn’t know we would end up there, but sometimes that’s the way science works,” German said with a laugh.

The study that spawned the discovery, titled “The accuracy of mechanical measurements at the macroscopic scale is limited by the inherent structural heterogeneity of the human stratum corneum,” began with German’s roots in mechanical engineering and his interest in test the validity of Hooke’s law on human skin.

“We figured that if we use these standard testing techniques to measure the mechanical properties of tissues, especially skin tissue, are they reporting the right values? ” he said. “No one has really ever validated it.”

Developed by 17th century British physicist Robert Hooke, the law states that the force required to extend or compress a spring over a distance is proportional to that distance. More generally, researchers can use this law to measure the stiffness of different materials as well as the amount of energy it costs to break them.

“It made me think that in modern times you can measure the stiffness of metals and ceramics. But what about the skin? Said the German. “Metals or ceramics have a fairly uniform composition, but skin and other tissues have a complex and heterogeneous structure with microscopic cells connected by cell-cell junctions. The outer layer of the skin also has a complex topographic network of microchannels, which are visible if you look at the back of your hand. “

He and Lipsky glued skin samples to a piece of polydimethylsiloxane (PDMS), a rubber-like material commonly used in bioengineering and biomedical devices. The samples were then stretched. A modified tensile force microscopy technique was then used to quantify the changes in the mechanical loads imparted by the skin to the adherent substrate.

“As the skin dilated, a little crack would develop, and we can measure the amount of energy needed to make it grow to a certain length,” German said. “Typically, to measure the energy cost of failure in mechanical engineering, you get two handles, you pull, and it splits. You measure force and displacement and quantify energy. But this assumes that the material is homogeneous – the composition is the same everywhere. we found that the cracks in the outer layer of the skin spread in a very, very strange way. “

The cracks propagate along the topographic microchannels. This lengthens the overall path of the crack, increasing the energy it takes to break the tissue. The finding can be extrapolated to explain the behaviors of other human tissues.

“Due to the heterogeneous structure of the skin, it also means that the path to the crack becomes much more random. This is why you get such variability in large-scale blood pressure measurements of the skin,” German said. , “because even though you get the skin from the exact same source at the exact same age, the variability from sample to sample is so high because the crack paths diverge.”
