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.

As organizations continue to believe the malicious use of artificial intelligence (AI) will outpace its defensive use, new data focused on the future of AI in cyber attacks and defenses should leave you very worried. It all started with the proposed misuse of ChatGPT to write better emails and has (currently) evolved into purpose-built generative AI tools to build malicious emails. Or worse, to create anything an attacker would need using a simple prompt.

Every day, an average of 450,000 new malware are designed to wreak havoc on businesses, governments, and average citizens. Aside from the financial implications of malware, the reputational damage for companies and the psychological impact on victims (especially with ransomware) are enough to scare anyone at the thought of dealing with a malware attack. But it’s not all bad news! There is a way of protecting your devices and cyberspace with a proactive method.

The Kroll Detection and Response Maturity Model analyses 1,000+ security programs from organisations around the world to identify their actual maturity, the ROI of mature programs and what security leaders can do to elevate their detection and response capabilities. The report leverages data uncovered in our The State of Cyber Defense 2023: The False-Positive of Trust, which looked at responses from 1,000 global security decision-makers.

With the changing security landscape, the most daunting task for the CISO and CIO is to fight an ongoing battle against hackers and cybercriminals. Bad actors stay ahead of the defenders and are always looking to find new vulnerabilities and loopholes to exploit and enter the business network. Failing to address these threats promptly can have catastrophic consequences for the organization.

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.
