Amishra,

You are correct, signature based detection is a weak approach and can
be easily bypassed. Some vendors like Fireeye have tried to come up
with solutions to defend against APT, or zero day, but that all could
very well be vendor speak. I'm not sure as I don't have experience
with them, The best defense, is strong best practices things like:
-baselines (monitoring for changes in the baselines)
-log monitoring (egress and ingress)
-IDS/Firewall at the perimeter and within in the network
-patching
-user training
- Incident Response Policy
-etc
