Myself testing my internal firewall from external network,What were the effective ways of testing my firewall and ensuring that it secure
The methods which i tried were launching a stealth scan with sending ack packets to the firewall and checked whether my firewall filtering all my ports,
using nmap i tested using following commands :
nmap -v -sA -n mydomain -OA firewallaudit
other than that i tried to repeatedly ping the firewall and tested whether it rejects and blocks the floods of attacks
Its an internal firewall and myself testing for internal and external attacks,
the above said were the normal tests which i carried out to test my internal firewall,other than above anyother options to ensure that firewall is safe?how can i test my firewall that its efficiently configured or not?
