Redis को secure करना महत्वपूर्ण है क्योंकि, default रूप से, एक exposed Redis instance एक गंभीर vulnerability हो सकता है — open Redis servers ने कई वास्तविक breaches का कारण बना है। Security में authentication, network restrictions, TLS, command restrictions, और सावधान configuration शामिल हैं।
Network security (सबसे महत्वपूर्ण)
⚠️ NEVER expose Redis directly to the internet. By default Redis trusts anyone who
can connect → an exposed instance lets attackers read/delete data, or worse.
✓ BIND to localhost/private interfaces only (bind 127.0.0.1 / private IPs)
✓ Firewall / security groups → only allow trusted app servers to reach port 6379
✓ Run Redis in a private network/VPC, never publicly accessible
→ Most Redis breaches stem from instances left open to the internet. This is #1.
