How to Protect Networks against Advanced Evasion Techniques(AET)
Evasion techniques evade the exiting network security devices such as signature based  IPS and firewalls to enter the internal network to deliver exploits in servers. Most of the Intrusion detection and prevention system rely on attack signatures to identify malicious strings in the traffic. The strings used to evade the devices are not malicious themselves. Their main purpose is to pass through IDS without triggering alarms. [Read more…] about How to Protect Networks against Advanced Evasion Techniques(AET)
VRRP Configuration(virtual router redundancy protocol)
VRRP or virtual router redundancy protocol provides router or switch interfaces failover and failback facility for seamless operation of a network. VRRP almost similar to HSRP in terms of operations and functions, but with a few added features such as VRRP supports up to 255 groups.
Just like HSRP, VRRP also support a number of routers to form a virtual group which acts like a single router. Every access request send to the virtual IP is responded regardless of the fact which router is in active mode. In VRRP only one router will remain active to forward all the traffic send to its Virtual IP address, and there will be one standby router and several candidate routers. In case of the active router failure or its interface failure, the role of active router will be shifted to the sandy router. And when the active router will be back in operation it will resume its responsibility as an active router. [Read more…] about VRRP Configuration(virtual router redundancy protocol)
