Written by Linux security expert and Founder Dave Wreski.

Attacks targeting Linux have surged in recent years due to the mass migration of workloads to the cloud and the increase in IoT and other connected devices on the network. Traditional endpoint security solutions for Linux, which typically rely on the same algorithms and techniques developed to secure Windows desktops and don’t address the attack patterns unique to Linux, are no longer sufficient to secure modern Linux workloads against today’s dynamic and evasive threats.

Luckily, solutions that address Linux-specific challenges to fortify today’s Linux workloads against the most sophisticated and damaging threats do exist. An automated and efficient platform I’ve been using to detect and remediate threats to my Linux environment—and must admit I am quite impressed with!—is Vali Cyber’s ZeroLockTM. In this article, I’ll examine the modern Linux threat landscape in a nutshell, introduce ZeroLock, and demonstrate how ZeroLock works to mitigate a ransomware attack.

The Modern Linux Threat Landscape in a Nutshell

The rise in popularity of Linux in recent years has put a target on the OS’s back. Linux malware reached an all-time high in the first half of 2022. The total number of vulnerabilities detected year-over-year shows that after Microsoft and Apple, it’s Linux distros like RedHat and Debian that have the highest numbers of vulnerabilities reported.
