Open-Source Kernel Security Technologies

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Kernel security is a key determinant of overall system security. After all, the Linux kernel is the foundation of the OS and the core interface between a computer’s hardware and its processes.  Luckily, Linux now supports a range of effective open-source extensions and external tools engineered to boost kernel security. From the threats you should be aware of to the initiatives and technologies designed to reinforce and enhance the security of the Linux kernel, here's what you need to know.

Linux Pentesting: What Is It and How Can It Improve Network Security?

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

When setting up and testing a network security system, it is critical to make sure it is working properly and free from vulnerabilities that could be exploited by malicious hackers. While the best way to guarantee the security of a system is to design, implement and operate it to be secure, continuously testing a network security system for potential flaws is an excellent way to improve and validate network security - which is where pentesting comes in quite handy. This article will introduce the concept of pentesting to improve and verify network security, explain basic pentesting methodology and explore some excellent pentesting tools, distros and OSes available to Linux users in 2021.

Modernize Your Intrusion Detection Strategy with an AI-Powered, Open-Source NIDS

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

As 2020 comes to an end, cyber risk has reached an all-time high, and intrusion detection has never been more essential in securing networks and preventing attacks and breaches. Cyber criminals’ methods, tactics and techniques are evolving to become increasingly stealthy and sophisticated, and more organizations than ever are turning to AI-based intrusion detection systems to beef up their security defenses, outsmart the “bad guys” and protect their critical servers, systems and data.

Verifying Linux Server Security: What Every Admin Needs to Know

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Linux is a widespread OS known for its robust security. That being said, vulnerabilities are inevitable in any OS, and Linux system administrators must be vigilant about monitoring and verifying the security of their servers on an ongoing basis in order to protect sensitive data and prevent attacks. After all, the majority of attacks on Linux systems can be attributed to poor administration.

OctopusWAF: A Customizable Open-Source WAF for High Performance Applications

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Mainstream web application firewalls (WAFs) can be very difficult to understand, with thousands of lines of code and obscure plugins. This complexity makes it challenging for developers to modify code to block specific anomalies and secure their applications. But OctopusWAF is different - the open-source WAF is customizable, user-friendly and optimized for a large number of parallel connections - making it ideal for high performance Asynchronous JavaScript and XML (AJAX) applications.
