Security update (patch)
In Turkish: Güvenlik güncellemesi (yama)
A software update that fixes a security flaw. Installing it promptly closes the door attackers would otherwise try.
When a flaw is fixed, the details often become public, which is why delaying an update is risky: the fix also tells attackers where the weakness was.
Phones, computers, routers, browsers and apps all need them. Automatic updates are the easiest way, and you should only download updates from the device's own settings or official store.
What to do
- Enable automatic updates on phone, computer and apps.
- Update your home router when its maker publishes new software.
- Ignore "update" pop-ups on websites; use the device settings.
