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

data:image/svg+xml,%3Csvg%20xmlns=%22http://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=%22http://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.

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

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

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.

Linux Server Security: A Getting Started Guide

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

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.

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 talking about open source, the first development environment that comes to mind is, of course, Linux. Halfway through 2020, around 50% of software developers say they use the Linux operating system (OS) for their projects.

Could Your Router Be The Biggest Security Flaw in Your Linux System?

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

Is your home router leaving your network vulnerable to attack? New research suggests that this worrisome scenario is more likely than you may have thought. A Fraunhofer Institute for Communication (FKIE) report reveals that the firmware used in a large number of popular home routers is susceptible to malware and other serious exploits in cybersecurity.

Over the past few weeks, a heated debate has arisen on the Apache SpamAssassin users list regarding the replacement of racially charged terms like “whitelist” and “blacklist” used in the Apache Spamassassin Project’s code with more inclusive language. Certain community members have been very supportive of Apache SpamAssassin’s efforts to remove racially insensitive language from the project, while others have loudly voiced their disapproval.
