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.

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.

WireGuard Brings Speed and Simplicity to VPN Technology

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

VPN technology has become a critical part of our digital lives, serving a variety of purposes including securing wireless connections, resolving geographical limitations, reaching prohibited websites and protecting the privacy of sensitive data. However, the unfortunate reality is that many of the VPN protocols on the market today are comlex, slow, unstable and insecure. Luckily, the new, innovative Wireguard protocol has demonstrated significant promise in all of these areas - and has earned a place in the mainline Linux kernel as a result. This article will briefly explore VPN protocols and potential concerns when implementing a VPN, and will dive deeper into the unique benefits that Wireguard offers users.

When it comes to using a NoSQL document database to store, manage and retrieve documents, reliability, privacy, efficiency and ease-of-use are essential in optimizing productivity and ensuring data security. However, the unfortunate reality is that many NoSQL document databases fail to embody these important characteristics, leaving users frustrated - and often at risk.

How To Identify Libraries that are Still Vulnerable to Attacks After Updates

Patch management can be a complex and time-consuming process, and because of this, patches to fix vulnerabilities may not be applied before a hacker is able to breach an organization's security. The majority of organizations are not aware of these vulnerabilities until they have experienced a breach, at which point it is frustrating to learn that deploying a simple patch could have prevented the breach altogether.

Are your Linux servers secure? No machine connected to the internet is 100% secure, of course. In the words of security guru Bruce Schneier: “Security is a process, not a product.” However, this doesn't mean that you are helpless. Although cyber attacks, hacks and breaches are sometimes unavoidable, all system administrators and users can take definitive measures to mitigate their risk online.
