Security attacks are stealthier than ever. Pervasive protection is needed. When should it be implemented?

Pervasive protection is needed 'All of the above' (before, during, and after an attack) because modern security requires a continuous, multi-stage approach. Threats must be prevented before they occur, detected and contained during their active phase, and thoroughly remediated with lessons learned after the incident to ensure long-term resilience and improve future defenses.

Relying solely on protection 'After the attack' means that the damage has already been incurred and potentially spread, making the approach purely reactive rather than effectively pervasive or proactive.

Implementing protection only 'During the attack' is insufficient as it misses crucial prevention opportunities and can lead to prolonged impact and damage before full mitigation can be achieved.

While implementing protection 'Before the attack' is crucial for preventing known threats, it does not account for zero-day exploits, sophisticated evasion techniques, or determined attackers who might bypass initial defenses, necessitating continuous detection and response capabilities.
