Cybersecurity is a top priority in the digital age, where cyber threats to systems and networks are increasing every day. One of the key tools for protecting computer systems is the Host Intrusion Detection System (HIDS). This article details how HIDS works, its benefits and provides practical examples for a better understanding. What is a…
Security in corporate networks has become more complex with the increasing diversity of devices and users connecting to them. One of the most effective solutions for managing and securing network access is NAC (Network Access Control).

In this series, I’m going to write about some basics in Linux kernel exploitation that I’ve learned over the past few weeks: from basic environment configuration to some popular Linux kernel mitigations, and their corresponding exploitation techniques. Requirements: Responsibility: In this tutorial we will use hacking techniques, with the only purpose of learning. We do…
Many people are asking me about Active Directory attack prevention methods and a good way for a critical vulnerability scan, which then leads me to get the domain administrator in fifteen minutes by simply exploiting misconfigurations in AD. Requirements: Responsibility: In this tutorial we will use hacking techniques, with the only purpose of learning. We…
Nowadays we all know what an antivirus is, we know what we must have to stop a virus from entering our computer and making it unusable. The basic theory is fine, but to really know in depth what an antivirus does? I will explain in depth what it is and the reason for having it.…
Short for Server Message Block, SMB is an application layer protocol that enables file, printer and device sharing and inter-process communication (IPC) between applications on a network through a client-server architecture. In other words, computers (SMB clients) on a network can connect to SMB servers to access shared files and directories or perform tasks such…
Command injection is a cyberattack that involves the execution of arbitrary commands on a host operating system (OS). Typically, the threat actor injects the commands by exploiting an application vulnerability, such as insufficient input validation. Requirements: Responsibility: In this tutorial we will use hacking techniques, with the only purpose of learning. We do not promote…
What is a CASB? According to Gartner, a cloud access security broker (CASB) is a security policy enforcement point, either on-premises or in the cloud, located between cloud service consumers and cloud service providers, whose purpose is to combine and enforce corporate security policies when accessing cloud resources. The CASB is like a policeman enforcing the laws…
A proxy is a well-known technology in the market, although sometimes it is not well understood how it works. Therefore, in this opportunity we will explain what a proxy is and how it is useful. But before we start talking about the logical structure of proxy servers, I consider it important to clarify how it…
