Your first line of defense should always be security practices that prevent an intrusion such as firewalls, intrusion prevention systems and keeping your system patched and up-to-date. However, it is also useful to try to ensure that your system has not been compromised. One way to help with this is by using a file integrity monitoring solution. These solutions work by comparing the checksums or the files on your system to their previous versions and alerting about changes.
