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.

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, a widely used web browser, serves millions of internet users by connecting them to the online world. Unfortunately, severe vulnerabilities can occur that threaten the security of its users.

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.

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.

Digital transformation, powered by the principles of open-source security , is vital for businesses looking to excel in today's technology-driven landscape. Customers, employees, and partners demand easily accessible, seamless digital experiences that integrate securely with their daily lives. By adopting open-source digital strategies, companies improve operations, foster stronger relationships, and fortify their cybersecurity posture.

Microsoft's recent patch, intended to strengthen Secure Boot defenses, has resulted in an unexpected setback for Linux-Windows dual-boot setups worldwide. Users and administrators encountering problems while trying to power on their Linux systems have received confusing error messages instead of the familiar boot sequence, leading them down a rabbit hole of frustration searching for solutions. Users try their hardest to use their systems again but fail miserably due to incompatibilities between them and Secure Boot's security protections.

The Linux kernel, the central nervous system of many devices worldwide, interfaces computer hardware and its processes and user processes. Because of its prevalence and importance, vulnerabilities within its code are of grave concern.

In modern business, Linux and open-source software form the backbone of countless enterprises, driving the engine behind essential applications and infrastructures globally. Renowned for their unparalleled openness and adaptability, these systems empower organizations with customization and control seldom found in proprietary counterparts.

The landscape of cyber threats and Linux vulnerabilities is evolving at an unprecedented pace, making it imperative for organizations to adopt advanced security measures. While effective to an extent, traditional quality assurance (QA) methods may no longer suffice against sophisticated cyberattacks.

Artificial Intelligence in business is slowly becoming the norm and necessary in the competitive struggle. Today, it is a powerful tool for developing companies, solving business problems, performing deep analytics, and automating processes.

In an era where digital transformation is accelerating at an unprecedented pace, cybersecurity has become a critical battleground for businesses and individuals. 2024 is shaping up to be a pivotal moment for the cybersecurity landscape, with emerging trends poised to redefine how we approach data protection, threat mitigation, and overall digital security.

Code signing involves approving applications, software code, scripts, or programs to authorize their origin. The goal is to ensure that the code is never tampered with. Certificate Authorities (CA) confirm the identity of the code-signing source and link a public key to a code-signing certificate.

Tails (The Amnesic Incognito Live System) offers hope to privacy activists and anyone seeking anonymity online. A live operating system and secure Linux distro that can be started from any USB stick or DVD, Tails provides anonymity by routing internet connections through Tor and leaving no trace on computers being used unless explicitly asked by the user.

As cybersecurity evolves, so too has its threats. Symantec recently identified an emerging threat aimed at Linux systems. This new type of ransomware (called double extortion by its creators) encrypts files and exfiltrates and holds onto data, demanding ransom payments in return. Such sophisticated cybercriminal tactics highlight their audacity while attacking many enterprise and cloud environments - an audacious move by cybercriminals targeting such essential infrastructure as server farms.
