What if you could block connections to your network in real-time from countries around the world such as Russia, China and Brazil where the majority of cyberattacks originate? What if you could redirect connections to a single network based on their origin? As you can imagine, being able to control these things would reduce the number of attack vectors on your network, improving its security. You may be surprised that this is not only possible, but straightforward and easy, by implementing geographic filtering on your nftables firewall with Geolocation for nftables.

When setting up and testing network security websites or systems, it is critical to ensure they work correctly and do not have cybersecurity vulnerabilities that malicious hackers could exploit. The best way to improve and guarantee data and network security while preventing attacks is by continuously testing the system for potential flaws. Pentesting is an incredibly helpful tool that can be utilized to protect your company. This article will introduce Linux pentesting and its benefits, explain the basic methodology, and explore some excellent network security toolkits available to Linux users.

For many years, Windows users were the only ones at risk of facing malware network security threats; however, cybercriminals have come to view Linux as a viable target for their attacks due to the growing popularity of the open-source OS and the plethora of high-value devices it powers. During 2019 and 2020, dangerous Linux malware variants like CloudSnooper, EvilGnome, and HiddenWasp emerged, and the number of malware strains continued to grow over time as Linux malware operators harbored great success with their malicious malware and phishing campaigns. Thus, taking proactive measures to secure your Linux systems against attacks has never been more critical.

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.

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.

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.
