Patch management
Deploying security updates on time to close known flaws.
Patch management consists of identifying known flaws, obtaining the vendors' updates, testing them and then installing them quickly. It is one of the most effective measures against opportunistic attacks, which target precisely the software that has not been updated. The difficulty is mainly organisational: knowing what you have, and prioritising.
