Protecting the data of an organization is a complex task. Data is the crown jewel of any organization which the adversaries continuously seek to get their hands on. Data is threatened both by external attackers and internal threats. Sometimes the threats are malicious, and in many cases, they are accidental. Both these cases have to be addressed by modern enterprise security departments.
The REvil ransomware (a.k.a Sodinokibi) is a threat group that operates in the RaaS (Ransomware-as-a-Service) model, where the infrastructure and the malware are supplied to affiliates, who use the malware to infect target organizations. On July 2, the REvil threat group launched a supply chain ransomware attack using an exploit in Kaseya’s VSA remote management software. REvil claims to have infected more than one million individual devices around the world.
When did you first see a network operations center (NOC)? For me, it was 1983 at BBN in Cambridge. With some whiteboards, a few terminals, and a handful of chairs, it was modest compared to ones I’ve seen since–but it was also the NOC for the whole internet at the time. Even then, that significance made it a pretty cool place.
The following is an excerpt from Netskope’s recent book Designing a SASE Architecture for Dummies. This is the seventh, and final, in a series of seven posts detailing a set of incremental steps for implementing a well-functioning SASE architecture.
Cybersecurity has a bad rap for getting in the way of business. Many CIOs & CISOs dedicate a lot of time to minimizing security solutions’ performance drag on their network traffic while ensuring that the solutions continue to do their job keeping the network secure. The move to the cloud exacerbates this challenge.
Attackers have long used phishing emails with malicious Microsoft Office documents, often hosted in popular cloud apps like Box and Amazon S3 to increase the chances of a successful lure. The techniques being used with Office documents are continuing to evolve. In August – September of 2020, we analyzed samples that used advanced techniques like: In January 2021, we examined samples that use obfuscation and embedded XSL scripts to download payloads.
The following is an excerpt from Netskope’s recent book Designing a SASE Architecture for Dummies. This is the sixth in a series of seven posts detailing a set of incremental steps for implementing a well-functioning SASE architecture. Throughout this series, we repeat that the data center is just one more place people and data have to go—it’s no longer the center of attention.
The Financial Times hosted an excellent event recently, at which I joined Naina Bhattacharya, CISO for Danone; Manish Chandela, Group CISO for Unipart and Florence Mottay, Global CISO for Ahold Delhaize, to discuss cloud security. The FT’s Dan Thomas moderated and the panellists all shared some excellent and candid insights into cloud threats and security strategies within their organisations.
Another memo, another leaky cloud app compromising the personal information of hundreds of thousands of individuals (and yes, you can easily guess the app that exposed the data so no spoiler alert needed—it was an S3 bucket). The latest organization to join the long list of victims of cloud misconfigurations is Cosmolog Kozmetik, a popular Turkish online retailer that exposed more than 9,500 files, totaling nearly 20 GB of data.
If our friends Security and Networking were on Facebook, they would probably both list their relationship status as “It’s Complicated.” Sometimes everything’s great, but now and then things can get a little weird, unclear, or uncomfortable. At many organizations, there has traditionally been a barrier between the security and networking teams. Each team has its own objectives — and at times, those objectives can be at cross-purposes.
