There are many factors to consider when choosing an OS, security being among one of the most critical. The general consensus among experts is that Linux is the most secure OS by design - an impressive feat that can be attributed to a variety of characteristics including its transparent open-source code, strict user privilege model, diversity, built-in kernel security defenses and the security of the applications that run on it.
Linux servers are at greater risk than ever. While only a few years ago Linux users could count themselves as the “lucky few” who didn’t have to worry about malware and computer viruses, this era has unfortunately come to an end.
Most of us are familiar with Microsoft Windows or macOS - these OSes dominate the personal computing space. But the OS that is taking over the world isn’t owned by Microsoft, Apple, or any tech company for that matter.
Predator-OS is a free and open-source secure Linux distro that is ideal for penetration testing, ethical hacking and digital forensics, but is also a great option for any user looking to improve his or her privacy and anonymity online with a security-centric, hardened OS.
Tails, or "The Amnesic Incognito Live System", has released the latest version of its privacy-focused secure Linux distro, Tails 4.21, with various changes, bug fixes and improvements including:
Regardless of the Linux distribution you’re using, staying on top of the latest security advisories is essential in maintaining an updated, secure Linux system.
Black Hat USA 2021 and DEF CON 29 have come to an end, and this year’s events did not disappoint, generating plenty of cybersecurity news, highlighting key industry trends and introducing some exciting new products. LinuxSecurity has been following both conferences, speaking with expert trainers and presenters and keeping our followers up-to-date on Twitter.

On July 8, 2021, the CrowdSec team released CrowdSec v1.1.x - the latest version of their free and open-source cybersecurity solution designed to protect Linux servers, services, containers, or virtual machines exposed on the Internet with a server-side agent - with new packages and repositories, as well as improvements to to the CrowdSec agent itself. LinuxSecurity spoke with the CrowdSec team to provide readers with insight into what they can expect from this exciting release, and how they can get started with CrowdSec v1.1.x.
Technology is an integral part of our everyday lives. Widespread reliance on devices that connect us to the Internet and cloud platforms that facilitate digital communications has markedly increased since the beginning of this pandemic. As technology companies are scrambling to meet businesses’ and consumers’ evolving needs, one trend has become clearly apparent - open-source is at the forefront of modern technological innovation, revolutionizing careers available in the field of cybersecurity in the process.
To say that it’s an exciting time in the cybersecurity community is an understatement! Two of the most prestigious cybersecurity conferences - Black Hat USA 2021 and DEF CON - are rapidly approaching, featuring an impressive list of trainings and presentations.
It is no secret that email is the preferred method of communication for businesses - a trend that has only been magnified with the increase in remote workers brought on by the pandemic. That being said, email is effectively a plaintext communication sent from email clients to receiving email servers or from one server to another, leaving the content of messages in transit vulnerable to compromise without additional protection via encryption technology such as the Transport Layer Security (TLS) standard.
The Linux vulnerability landscape is becoming increasingly complex, in part due to a seemingly never-ending number of new vulnerabilities that are constantly surfacing.
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.
