ISO 27001 Incident Response
When under a cyberattack, seconds are worth years. What determines the magnitude of the damage is not how clever the attack is, but how organized the defense is in the first 24 hours.
No security system is flawless, and ISO 27001 places this reality at its core. Knowing what to do when a security breach occurs (when a server is infiltrated, data is stolen, or encrypted) is the core of the Incident Response (IR) process. In the event of a successful breach, the organization must instantly transform into an autonomous war cell.
The first and most critical rule of cyber incident response is the Containment phase. The moment an attack is detected, infected machines must be immediately isolated from the network; however, pulling the plug shouldn't destroy the evidence. The volatile data in the system memory (RAM) is the only trace that will reveal the identity and method of the attacker from a digital forensics perspective.
The second dimension is the Communication and Compliance step. When a data breach occurs, not only technical teams but also legal departments must step in. Regulations such as GDPR or local equivalents mandate that the breach be reported to authorities and affected users within a very short period (e.g., 72 hours). Without a pre-prepared Incident Response Plan (IRP), deciding who will say what, and when, turns into massive chaos.
