Network IPS Evasion Techniques

Hi,

I am currently using two IPS 4255 and 4260 with 7.1.7 E4 patch as far as my knowledge that IPS only study plain text while it will not sniff the encrypted data. I study today in the Network IPS Evasion Techniques the attacker use these techniques to by pass the IPS sensor.

1- Do educate me what is method to use Cisco IPS Anti-Evasion Features in my current sensor to defend my LAN network from attacker?

2- Is updated signature is enough to defend these envasion method?

3- Or is there any other method to enable the feature in the above mentioned IPS what are these?

Thanks & Regards,

Salman Ahmed
