Most breaches do not start with a clever new attack. They start with a known weakness that nobody fixed. When a vendor publishes a security update, it also tells the world exactly where the old version was broken. Attackers read those notes as carefully as defenders do, and they build working exploits within days. Every system that runs the old version after that point is a target with a published map to the door. This is why patching is a race, and why the winner is decided by routine rather than skill. A good patching routine starts with knowing what you own. You cannot update a server that nobody remembers, a plugin that was installed years ago, or a router in a cupboard that came with the office. Keep an inventory of every system, its version, and who is responsible for it. Next, rank the updates by risk. A flaw that lets a stranger run code over the internet needs fixing within 7 days, while a low risk bug in an internal tool can wait for the next maintenance window. Test the fix on a copy first, because an update that breaks the business creates its own kind of damage, but do not let testing turn into delay. Turn on automatic updates wherever the risk of a bad update is smaller than the risk of an old one, and check that they ran. Finally, measure the result. Track how long it takes from the day a fix is released to the day it is installed everywhere. If that number keeps shrinking, the organisation is getting safer. If it keeps growing, no firewall or antivirus product will make up for it. Security is rarely about stopping the perfect attack. It is about being too well maintained to be the easiest victim.
