Redis-ஐ secure செய்வது critical ஆகும், ஏனெனில் default-ஆக, exposed Redis instance ஒரு serious vulnerability-ஆக இருக்க முடியும் — open Redis servers பல real breaches-ஐ cause செய்துவிட்டன. Security authentication, network restrictions, TLS, command restrictions, மற்றும் careful configuration-ஐ involve செய்கிறது.
Network security (most important)
⚠️ 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.
