An IDS (Intrusion Detection System) is a type of detective control, which means it is designed to detect or discover security events that have already occurred within a network or system.

Detective controls are used to identify security incidents, security weaknesses, or violations of security policies, and they do not prevent incidents from occurring. Instead, they are used to provide a warning or notification of a possible security breach, allowing security personnel to respond quickly and appropriately.

Corrective controls, on the other hand, are designed to mitigate or eliminate the impact of a security incident after it has occurred. These controls can include actions such as system backups, data restoration, and incident response procedures.

Physical controls are security measures that are designed to physically protect a system or network from unauthorized access, damage, or theft. Examples of physical controls can include locked doors, security cameras, and biometric access controls.

Administrative controls are policies, procedures, and guidelines that are put in place to manage and govern an organization's information security program. Examples of administrative controls can include security awareness training, access controls, and incident response planning.

In summary, an IDS is a type of detective control that is designed to detect security events that have already occurred within a network or system.
