OWASP Top 10 #1: Broken Access Control And Security Tips

The Open Web Application Security Project (OWASP) is a community working to improve the security of information systems and more specifically applications (web, mobile, APIs).

This organisation produces numerous resources, in particular guides and standards for application security, including the OWASP Top 10. It also develops open source tools such as ZAP (an interception proxy, an alternative to BURP), or Amass (to map its attack surface).

What is data pseudonymisation?

What is Pseudonymisation? Techniques and Best Practices

Pseudonymisation is a data protection technique, which consists of processing data in such a way that it is not possible to attribute them to a specific person without the use of additional information. More specifically, it involves replacing real personal identifiers ( last names, first names, emails, addresses, telephone numbers, etc.) with pseudonyms.

What is privilege escalation?

Linux Privilege Escalation: Techniques and Security Tips

Privilege escalation is a key concept for attackers seeking access to sensitive information or restricted functionality on an information system. Typically, this involves exploiting security weaknesses in a given system to escalate from a limited level of access, with standard permissions, to a higher level of access, with greater rights.

On Linux, there are several techniques for escalating a user’s privileges. Exploitation of configuration weaknesses, vulnerabilities in programs and broken access control are the main ones.


When developing a game, you may need to save a player’s run to a file so that you don’t lose their progress and they can return to where they left off. Similarly, when developing an online text editor, you may want to preserve the content that the user has written.

Indeed, there are many cases where we want to save the state of our application to restore it in the future. Two terms are used to define this process: serialization and deserialization.

Brute force is certainly one of the most trivial attack techniques. The main reason: the human factor remains the weakest link in the cybersecurity chain. Indeed, there is no need to carry out social engineering attacks or sophisticated SQL injection attacks to steal credentials because habits die hard: users’ passwords remain weak and therefore easy to guess. With the right tools, even the most novice attackers can compromise data and cripple the systems of large companies.

Server security is a major issue for companies. Indeed, being a central element in the functioning of all the components of an information system (applications, network, infrastructure, employees, etc.), servers are often the prime targets of attacks.
