Recent ransomware attacks called WannaCry and Petya have been making headlines. They are demonstrating just how vulnerable many computer systems are to attack. Tens of thousands of systems have been affected by these ransomware attacks and they should be making you consider how vulnerable your systems are.
The type of ransomware attack used by WannaCry and Petya encrypt data, making it unreadable, and then demand payment to decrypt the data. They both attacked a vulnerability exposed in Windows operating systems that were not updated to a sufficiently recent patch level. While your systems may not have these specific vulnerabilities, it is impossible to prepare for every new or existing vulnerability that may be the target of the next attack. In addition to making your systems less vulnerable to attack, it’s a pretty good idea to have a plan for how to deal with a successful attack on your systems.
