What Is Threat Intelligence?

What Is Threat Intelligence?

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Thank you to Oyelakin Timilehin Valentina and Duane Dunston for contributing this article. Threat intelligence (or threat intell) is information used to understand past, present, and future threats targeting an organization. It is evidence-based knowledge about a previous, existing or emerging threat to organizational assets. Threat intelligence also includes settings, implications, mechanisms, context, and even action-oriented advice on the threat. Context mentioned here includes who the attackers are, what their motivation is, what their capabilities are, and what indicators of compromise are in your system. An Indicator of compromise (IOC) is forensic data in a system log file, for example, which identifies malicious activities on a system or network.

On Wednesday, May 12th, in the wake of the recent Colonial Pipeline ransomware attack that shut down one of the largest US pipelines for nearly a week, President Biden signed an executive order placing strict new standards on the cybersecurity of all software sold to the federal government. This order is part of a broad, multi-layered initiative to improve national security by incentivizing private companies to practice better cybersecurity or risk being locked out of federal contracts.

Can Linux Be Used To Offer More Security In A WFH World (On And Offline)?

Can Linux Be Used To Offer More Security In A WFH World (On And Offline)?

Operational security at least seemed so much easier back when traditional 9-to-5 office life was still dominant. Talk of professionals taking their work home with them was largely metaphorical, with only occasional instances of C-suite types dragging their laptops everywhere they went. Business hardware and systems would be shielded through physical security and isolated networks. One office (or office complex), one place to guard: entirely straightforward.

Kernel security is a key determinant of overall system security. After all, the Linux kernel is the foundation of the OS and the core interface between a computer’s hardware and its processes.  Luckily, Linux now supports a range of effective open-source extensions and external tools engineered to boost kernel security. From the threats you should be aware of to the initiatives and technologies designed to reinforce and enhance the security of the Linux kernel, here's what you need to know.
