Cyber-security is a lot like military strategy. Both involve a battle of wills between adversaries that includes the use of force. It’s no wonder why cyber-security practices often borrow from military tactics.
One of those tactics is known as “defense in depth,” which is a layered approach to security involving multiple levels of defense designed to slow the attacker’s progress. Defense in depth is more than just a military strategy. It’s also a useful approach for protecting IT environments. It acknowledges that adversaries, through ever-evolving tactics and brute force, will eventually overrun the outer-most layer of defense. For this reason, it’s necessary to have additional layers of defense in place to anticipate and mitigate lost ground.
The ability to recover from adverse events – such as a ransomware attack – and return to normal operations is referred to as “cyber-resilience.” Achieving higher levels of cyber-resilience is a priority for any business that relies on access to data. Here are five tips for improving cyber-resilience based on a defense-in-depth approach.
