Nessus is a widely used cyber security tool developed by Tenable Network Security, a well-known cyber security company. Nessus is a vulnerability scanner that is designed to identify and assess vulnerabilities in computer systems, networks, and applications. Tenable maintains a Docker image that helps us to create a temporary, disposable Nessus server anytime we need one.
In this blog post, we will explore some of the steps we can take to harden our Debian desktop for more secure daily work and enhanced privacy. Hardening is the process of reducing the attack surface and increasing the resilience of a system by applying security measures and best practices. By hardening our Debian desktop, we can protect our data, identity, and communication from malicious actors and unwanted surveillance.
In the vast realm of the internet, there exists a fundamental system that silently orchestrates our online experiences. It’s called the Domain Name System (DNS), a behind-the-scenes hero responsible for translating human-friendly domain names into machine-readable IP addresses. Although often taken for granted, understanding how DNS works can shed light on the seamless browsing experience we enjoy every day. In this article, we unravel the intricate workings of DNS, demystifying its mechanisms and unveiling the crucial role it plays in the digital world.
The OWASP Top 10 is a widely recognized list of the most critical security risks for web applications. It is updated every few years based on data analysis and community feedback. The latest version, released in 2021, introduces some new categories and changes some existing ones to reflect the current threat landscape.
As developers, we should be aware of these risks and take steps to prevent them in our applications. In this blog post, we will briefly review each of the OWASP Top 10 categories and provide some best practices and resources to help us secure our code.
Hydra is a powerful tool that can help you perform penetration testing on various network services. Hydra can brute-force passwords for more than 50 protocols, such as telnet, FTP, HTTP, HTTPS, SMB, and databases. Hydra was developed by the hacker group “The Hacker’s Choice” and released in 2000 as a proof of concept tool. Hydra is also a parallelized login cracker, which means it can make multiple connections at the same time and reduce the time required to crack a password.

If you are looking for a reliable, secure and customizable operating system that gives you full control over your computing environment, you might want to consider Debian Linux. Debian is one of the oldest and most respected Linux distributions, with a history of over 25 years and a community of thousands of developers and users. In this blog post, we will explore some of the reasons why Debian is the ultimate operating system for more experienced users.
Kali Linux is a popular operating system for penetration testing and ethical hacking. It comes with a variety of tools and features that can help you perform security assessments, vulnerability scans, network analysis, and more. But what if you want to have Kali Linux with you wherever you go, without carrying a laptop or installing it on your main machine? The solution is to install Kali Linux on an UBS stick and boot from it whenever you need it. This way, you can have a mobile and robust system in your pockets that can run on any compatible computer.
If you are a Debian Linux user and you want to use Microsoft TrueType fonts on your system, you might be wondering how to install them. In this blog post, I will show you a simple and easy way to do it.
VPN stands for Virtual Private Network and it is a technology that allows you to create a secure connection to another network over the internet. VPNs are often used to access geo-restricted websites, protect your online privacy, and encrypt your data.
The internet is a vast and diverse place, but not all of it is accessible through the standard browsers and search engines that most of us use. There are hidden parts of the web that require special tools and techniques to access, and they are often referred to as the deep web and the dark web.
In the realm of system administration, security is paramount. One of the essential tools for maintaining a secure Ubuntu Linux environment is sudo, which allows authorized users to perform administrative tasks with elevated privileges. In this post, I will guide you through the process of installing and setting up sudo on Ubuntu Linux, ensuring a robust and secure system administration experience.
Penetration testing is a valuable tool for assessing the security posture of an organization. It simulates real-world attacks and identifies vulnerabilities that could be exploited by malicious actors. However, penetration testing alone is not enough to ensure a comprehensive security solution. There are several limitations and challenges that need to be addressed in order to maximize the benefits of penetration testing.
Continue reading “Why Penetration Testing Is Not a Full Security Solution and How the Local Security Team Does Not Follow the Recommendations”We all have secrets. Whether it’s our bank account details, our social media passwords, or our personal information, we don’t want anyone to access them without our permission. But how do we keep our secrets safe in the digital age, where hackers, phishing scams, and data breaches are frequent?
