Linux servers are a far more dominant force in the industry than people give them credit for. Sure, many personal computers run on Windows, but Linux is the operating system behind roughly 81% of all the websites. One reason for this is that it's more resilient to the majority of threats that most of their counterparts face.

The Linux operating system, widely acclaimed for its robustness and security , recently received widespread media attention due to a significant kernel vulnerability, CVE-2024-43856 . The issue involves race conditions in the dmam_free_coherent() function, which could allow race condition-based attacks against various kernel versions.

While Linux servers are already extremely secure by default, there are extra steps you can and should take if you do have a Linux server instance running. As with any system, vulnerabilities still exist and can wreak havoc if proper prevention and security best practices are not implemented.

Google Chrome, one of the world's most widely used web browsers, has recently been scrutinized due to the discovery of multiple Chromium vulnerabilities that threaten user safety and privacy. Chromium is the open-source web browser project that is the basis of Chrome and many other widely used browsers.

Ransomware has long been a severe threat to organizations and admins alike. Recently, cybersecurity researchers discovered a new variant called Cicada3301 , which some experts believe has links with BlackCat (aka ALPHV) due to similarities in operations. Cicada3301 is a Rust-based ransomware that targets Windows and Linux/ESXi hosts.

Buffer overflow vulnerabilities have long been one of the biggest headaches in computer security, especially on Linux operating systems that power everything from servers to smartphones. Linux admins must understand the origins and evolution of buffer overflows, not just academically; it's essential for securing our systems and our sensitive data.

With hundreds of thousands of open-source projects underway, it's easy to say that open-source has become a standard in software development. And when discussing open source, the first development environment that comes to mind is Linux.

As a Linux admin or an infosec professional, you understand how the security landscape changes due to evolving threats, newly discovered vulnerabilities, and more. With data breaches soaring into millions of dollars in losses and sullying reputations, making your Linux systems robust in this digital age is no longer just a best practice. It's a must.
