A field that consists of two branches of cybersecurity: digital forensics and incident response. It includes investigating, identifying, containing, and remediating cyber attacks. It could also potentially involve testifying in an investigation. It is used to restore businesses after an attack while also identifying and collecting evidence needed for insurance or to press charges against the attackers.
Digital forensics involves collecting, analyzing, and preserving evidence of an attack. It allows investigators to have a full picture of how the cyberattack happened.
Incident response is the steps businesses take when they have a cybersecurity incident. Its main goal is to get the infrastructure running while minimizing the damage at the same time. Incident response is usually prepared beforehand to allow businesses to react quickly in case of an attack.
