While most modern leading security products can generally be considered effective, they should not be viewed as complete protection against attack. So how can enterprise systems and networks ensure mission survivability in a cyber-compromised environment? The answer is – by becoming cyber resilient. Not every attack can be prevented, but with a cyber resilience program, damage can be mitigated or avoided altogether. Organizations must assume the breach will occur and proactively seek to reduce its impact. True cyber resilience allows systems and networks to continue to function regardless of the level of attack.
