I had this issue with Outlook Web Access traffic, I have disabled the rule
for now, at some point though I guess I should just create a pass rule for
the afftected box...

Subject: [Snort-users] WEB-MISC long basic authorization string
I'm getting the " WEB-MISC long basic authorization string " from source
IPs which are part of our internal network to one host. This host is an
internal web server whom our MIS changed the IP address just before these
alerts start flow. Now I've checked the signature definition which shows
that it takes consideration of the payload. What I would like to know that
if there is other legitimate traffic could fire up this signature..?coz I
don't think a big number of machines on the network are trying to attack
this one host..?
Would appreciate your thoughts
alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS 80 (msg:"WEB-MISC long basic
authorization string"; flags:A+; content:"Authorization\:
Basic "; nocase; dsize:>1000; classtype:attempted-dos;
reference:bugtraq,3230; sid:1260; rev:2;)
