Defence in depth (layered security)
In Turkish: Katmanlı güvenlik
Using several protections together, so that when one fails another still stands between an attacker and you.
No single protection is perfect. A strong password can leak, a second step can be tricked, and a backup protects only the data. Together they cover each other's gaps.
Think in layers: a unique password, a second step, up-to-date devices, careful clicking, and a backup if all of that fails.
What to do
- Do not rely on one protection; add a second step to strong passwords.
- Keep a backup even if you feel well protected.
- When one layer fails, check the others still work.
