How To Secure the Linux Kernel

With the support of the open-source community and a strict privilege system embedded in its architecture, Linux has security built into its design. That being said, gone are the days when Linux system administrators could get away with subpar security practices. Cybercriminals have come to view Linux as a viable attack target due to its growing popularity, the valuable devices it powers worldwide, and an array of dangerous new Linux malware variants that have emerged in recent years.

Strategies for Improving Linux Security Through Cross-Browser Compatibility Testing

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

In the dynamic landscape of web development, ensuring that applications perform uniformly across various web browsers is a vital aspect of user experience. This becomes increasingly important for Linux systems, where the default browsers and configurations range presents unique challenges. Cross-browser compatibility testing on Linux helps to identify and resolve these discrepancies, thereby enhancing the accessibility and functionality of web applications for all users.

Open-source software, or OSS, has completely changed the technology sector by enabling developers anywhere to work together and produce creative solutions faster. However, security issues are a significant worry, just like in any digital environment. Therefore, you should take precautions to secure any open-source software you use.

Hacker's Corner: Complete Guide to Keylogging in Linux - Part 1

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

This first part of the Complete Guide to Keylogging in Linux will explore keylogger attacks in network security. Keylogging can be valuable for testing within the Linux Security realm, so we will dive deeper into how you can write keyloggers and read events directly from a keyboard device on Linux.

IaC Security Scanning: Ensuring Security in the Open-Source Environment

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

IaC, or infrastructure as code, is essential to most cloud-based applications. Implementing IaC has advantages that significantly increase the service's characteristics and efficiency. However, as well as its enormous value, IaC has certain security drawbacks, like the spreading of simple security issues on all the files or vulnerability to data exposure, which could greatly affect the security of an open-source environment.

Best Practices for WordPress Site Security on Linux Webservers

At last count, W3Techs reported that 43.1% of all websites operating on the Internet today rely on the WordPress CMS. And of those, an overwhelming majority run on Linux servers. That immense popularity makes Linux servers running WordPress a prime target of hackers and other bad actors. As a result, such servers face an estimated 90,000 attacks every minute, every day.

IPv6 approach for TCP SYN Flood attack over VoIP, Part I

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

In this paper, we describe and analyze a network-based DoS attack for IP-based networks. It is known as SYN flooding. It works by an attacker sending many TCP connection requests with spoofed source addresses to a victim's machine. Each request causes the targeted host to instantiate data structures out of a limited pool of resources to deny further legitimate access.

IPv6 approach for TCP SYN Flood attack over VoIP, Part III

When a normal TCP connection starts, a destination host receives a SYN (synchronize/start) packet from a source host and sends back a SYN ACK (synchronize acknowledge). The destination host must then hear an ACK (acknowledge) of the SYN ACK before the connection is established. This is referred to as the "TCP three-way handshake."
