The training and skills medium
OSINT (Open Source Intelligence) is a method of collecting, analysing and exploiting public data to produce strategic intelligence. This data comes from open sources: social networks, websites, forums, government databases, satellite images, etc.
Unlike traditional intelligence (eavesdropping, espionage, etc.), OSINT focuses on information that is freely accessible, without illegal intrusion.
An OTP (One-Time Password) is a digital authentication code that is only valid for a single connection session or transaction. It is an additional security measure, often used in conjunction with a username and static password, to strengthen protection against identity theft and unauthorised access.
OWASP stands for Open Web Application Security Project. It is a non-profit online community working on web application security. Its philosophy is to be both free and open to all.
System parameters refer to all the technical configurations that determine the behaviour, security and performance of a computer system (operating system, applications, networks, etc.). In particular, they govern access to resources, security rules, user account management, activity logs and update policies. Incorrect configuration of these parameters is often an exploitable vulnerability.
A system parameter is a configuration option that tells a computer system how to behave. In practical terms, it is a setting that can be modified to adapt the operation of an operating system, server or software.
Examples:
On Windows, a system setting might be: force passwords to contain at least 8 characters
On a Linux server: prohibit SSH connections as root
On an Apache web server: limit the maximum size of an uploaded file
In a network, a parameter can be: only open certain ports for communications
These parameters influence system security, performance and stability. Poorly configured, they can create vulnerabilities that hackers can exploit.
