In this blog, I’ll share a few NetOps observations of the Black Hat network that I made during my time serving in the Black Hat Network Operations Center (NOC). My hope in doing so is to spark some ideas on how you can use an existing tool like Zeek for a new purpose. These insights were particularly revealing, despite not being linked to any security incidents.
At Corelight, we’re always striving to make the life of threat hunters and security analysts a little easier. It’s the reason we developed our Open NDR Platform that provides comprehensive, correlated network data and forensic evidence about everything happening on the network. If you’re familiar with Corelight, you probably already know that.
The explosion of interest in artificial intelligence (AI) and specifically large language models (LLMs) has recently taken the world by storm. The duality of the power and risks that this technology holds is especially pertinent to cybersecurity. On one hand the capabilities of LLMs for summarization, synthesis, and creation (or co-creation) of language and content is mind-blowing.
It has been a distinct honor to be a part of the Corelight team that helped defend this year’s Black Hat events. I started the event season in the Network Operations Center (NOC) at Black Hat Asia, and then capped it off at Black Hat in Las Vegas. In this blog I’ll share my experience and learnings from participating in both NOCs.
Zeek® is the world’s most widely used network security monitoring platform and is the foundation for Corelight network evidence. In this blog I share how to write a Zeek package in TypeScript with a new capability called ZeekJS that was released as part of Zeek 6.0.
What happens at the point in time when an organization’s information security is compromised? This blog explores an important paradigm shift that occurs at the very moment of compromise and that can be leveraged to turn the tables on the attackers.
During this year’s Black Hat in Las Vegas, I learned (or was reminded of) many lessons working alongside my Corelight colleagues and Black Hat Network Operations Center (NOC) teammates from Arista, Cisco, Lumen, NetWitness and Palo Alto Networks. The uniqueness of standing up a full security stack and NOC in such a short time with a team that comes together infrequently really forced me to consider how team processes and communication affect NOC/SOC efficiency and effectiveness.
The Corelight App for Splunk provides the foundation for organizations to boost SOC effectiveness and productivity by using Corelight data in Splunk. In this blog, I’ll walk through how the Corelight App leverages Splunk’s Common Information Model (CIM) to enhance users' search experience when they are using Corelight data.
Over the past few months, ransomware targeting healthcare organizations has been on the rise. While ransomware is nothing new, targeting healthcare organizations, at the extreme, can impact an organization’s ability to engage in anything from routine office visits to life-or-death diagnoses, treatments, and patient care.
