Keep devices and software updated
Apply operating system and application updates promptly — preferably with automatic updates — so known vulnerabilities get patched.
Why it matters
Vendors release updates when they find weaknesses. Delayed patching leaves devices exposed to attacks that already have known fixes. CISA recommends automatic updates and a weekly check for pending patches.
Practical steps
- Enable automatic updates for computers, phones, tablets, and browsers.
- Once a week, confirm pending OS and app updates have installed successfully.
- Update routers and other network gear from the manufacturer’s supported channels when patches are available.
- Retire devices that no longer receive security updates when practical.
- Install software only from official stores or vendor sites — not random third-party download pages.
