Need an in-depth introduction to a new security topic? Our features articles will bring up up-to-date on everything from buffer overflows to SE Linux policy development.
Whether you are a DevSecOps engineer responsible for managing your organization’s application infrastructure or you have your own personal Linux server that you use at home, the importance of keeping your systems safe and secure against malicious attacks by bad actors cannot be over emphasized.
Many of the kernel bugs present in the Linux system are potential security flaws. Hackers use the vulnerabilities inherent in the Linux kernel to gain privilege escalation or to create denial-of-service attack vectors.
Open Source is currently being recognized by more organizations than ever before for its ability to give rise to flexible, cost-effective and exceptionally secure software and technologies. Over 75% of organizations worldwide are now contributing to and consuming open-source software and products.
Linux prevails as the most popular OS among hosting providers - and for good reason. Linux is secure by design, cost-efficient, compatible with the majority of key programming languages used worldwide and offers high levels of customization.

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.
CloudLinux, the sponsor of the forever-free AlmaLinux OS enterprise Linux distribution, is now automating, simplifying and securing Linux operations with its TuxCare unified enterprise support services.
Since 1996, LinuxSecurity.com has served as the open-source community’s go-to resource for Linux news & Linux-related information, updates and engagement with community members who share a passion for Linux and security.
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.
Soon we will launch a brand new LinuxSecurity with a completely new experience. As part of a select group of LinuxSecurity users, we'd like to offer you early access to take the site for a spin and let us know what you think. How does it work for you?
The Qualys Research Team has discovered multiple critical vulnerabilities in the popular Exim mail server, which they have named 21Nails. Some of these flaws can be chained together to obtain full remote unauthenticated code execution and gain root privileges. With 60 percent of the world’s public email servers worldwide running on Exim, this set of flaws represents a serious threat to many organizations.
On Saturday, April 24th, 2021, the computer security world was shaken by the news of the sudden death of Dan Kaminsky, a renowned hacker best known for his contributions in the realm of DNS security. Kaminsky was 42 years old.
The CrowdSec team is expanding the capabilities of their open-source and free security solution by finalizing the release of its brand new application bouncer on the WordPress marketplace. This new bouncer is compatible for versions 1.0.x and beyond. Given that the vast majority of websites in the world are hosted on WordPress, this addition will improve CrowdSec's defense arsenal in its mission to defend the greatest number.
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.
Openwall recently announced the release of LKRG (Linux Kernel Runtime Guard) 0.9.0, featuring a host of major changes and improvements, as well as fixes for multiple security bugs. LKRG is a kernel module that performs runtime integrity checking of the Linux kernel and detection of security vulnerability exploits against the kernel.
Running PHP on a Linux web server is a prerequisite for the use of many popular applications such as Wordpress, Joomla and Drupal. Linux administrators and web developers must approach PHP with caution, as new vulnerabilities in poorly written and implemented PHP code are abundant and dangerous.
On April 12, 2021, the Apache SpamAssassin Project announced the release of Apache SpamAssassin Version 3.4.6 mitigating two small but potentially annoying bugs introduced in Version 3.4.5, which was created to fix a few security vulnerabilities just a few weeks ago.
