In my previous article, I proposed ways that modern network-derived evidence applies to the cyber kill chain—a concept created by Eric Hutchins, Michael Cloppert, and Rohan Amin that changed how security teams approach defending their digital assets. This article focuses on an evolved, non-linear version of the kill chain called the “kill web.”
The fusion of Cloud and AI is more than just a technological advancement; it’s a paradigm shift. As businesses harness the combined power of these transformative technologies, the importance of a security-centric approach becomes increasingly evident. This exploration delves deeper into the strategic significance of navigating the Cloud-AI nexus with a focus on security and innovation.
Today, we announced our largest funding round to date ($238M) at a new company valuation of over $3B. It’s a remarkable achievement that is indicative not only of Cato’s success but also of a broader change in enterprise infrastructure. We live in an era of digital transformation. Every business wants to be as agile, scalable, and resilient as AWS (Amazon Web Service) to gain a competitive edge, reduce costs and complexity, and delight its customers.
During Black Hat 2023 in Las Vegas, our Corelight team worked effectively and speedily with our first-rate Black Hat NOC partners Arista, Cisco, Lumen, NetWitness and Palo Alto Networks. I was fortunate enough to be a member of the NOC team at the show, helping to defend the Black Hat network. In this blog, I’ll share my experience within the Network Operations Center (NOC) as well as an incident that we detected, investigated, triaged, and closed using Corelight’s Open NDR Platform.
Network security has become paramount in safeguarding sensitive data and ensuring maximum efficiency in organizations today. As port scanning attacks increase, it’s important to stay vigilant to protect your enterprise systems from such threats. One essential tool that every network admin should have is the advanced network port scanner, which can help to identify and assess network port and switch port vulnerabilities.
The National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) 1.1 has been a critical reference to help reduce or mitigate cybersecurity threats to Critical Infrastructures. First launched in 2014, it remains the de facto framework to address the cyber threats we have seen. However, with an eye toward addressing more targeted, sophisticated, and coordinated future threats, it was universally acknowledged that NIST CSF 1.1 required updating.
In today’s cloud-driven landscape, containerized workloads are at the heart of modern applications, driving agility, scalability, and innovation. However, as these workloads become increasingly distributed across multi-cluster, multi-cloud, and hybrid environments, the challenge of securing them grows exponentially. Traditional network security measures designed for static network boundaries are ill-suited for the dynamic nature of containerized applications.
