Protection from zero-day exploits is difficult, but security measures can minimize the probability of them causing damage, even if an attack does take place.
While traditional anti-virus software isn’t effective against zero-day exploits because of the unknown virus signature, behavior-based security solutions can provide effective help. Intrusion detection systems (IDS) and intrusion prevention systems (IPS) monitor data movements and data access in the company with the help of algorithms and heuristics, and produce warning signals if anomalies are detected. Some of them automatically take countermeasures.
Businesses can reduce the danger of data misuse by implementing encryption, authorization systems, and checks.
Because any software could be the target of an exploit attack, the number of applications installed should be kept to a minimum.Companies should always use the most current version of a software and update software regularly (including available security updates). Applications that are not used should be removed from computers.
These measures can’t prevent an attack, but they can significantly reduce the risk of suffering financial damage through a zero-day exploit.
