Vulnerability
In Turkish: Güvenlik açığı
A weakness or mistake in software or a system that an attacker can use to get in or cause harm.
All complex software has flaws. When researchers or the company find one, the maker fixes it with an update; attackers then look for people who have not installed that update yet.
That is why installing updates is the single most useful habit for devices. You do not have to understand the flaw, only close it.
What to do
- Turn on automatic updates for your phone, computer and apps.
- Restart when an update asks, rather than postponing for weeks.
- Replace devices that no longer receive updates.
