System settings
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.
