Patches And Updates Must Be Deployed Quickly

Updating systems isn't typically as easy as people in the security community make it sound due to the presence of proprietary software that runs in a specific version of Java or Flash, according to Malwarebytes's Kujawa.

Businesses would be wise to examine ways in which they could deploy patches and updates across the entire organization without hindering day-to-day operations, Kujawa said. Bright IT employees should be able to ensure that nothing is killed or destroyed when a new patch is deployed, according to Kujawa.

Ransomware such as WannaCry has targeted exploits where a patch was already available, but organization hadn't yet gotten around to deploying it for their outward-facing systems, Kujawa said. This often happens because organizations assume they're not important enough for anything bad to happen to them, according to Kujawa.
