As a person just starting to use the Cisco ASA5505, I am trying to make sense of all the level 2 (critical) and level 3 (error) messages that are showing up in the log buffer. However when I posted asking about the seriousness of these messages, or to ignore them or not, there was no reply.
So I am forced to ask again, do we need to pay attention to the log buffer messages, or are they just for show? (sarcasm)
I see these messages whenever someone on the local inside interface is surfing the web and is at a web site. It almost appears like the web site itself is infected and other IPs are probing whenever a client lands on the web site, but I am not sure of this interpretation.
Do I need to stick in a packet analyzer between the static IP gateway and the ASA 5505 and trap every packet and take a careful look?
I would like to use the Cisco ASA5505 to its fullest advantage, but not spin my wheels fruitlessly either.
How much credibility should we place in these log messages?
