HTTP: Illegal Characters in Host Header Field (1)
This signature detects illegal characters in a Host header field of an HTTP/1.1 request. Attackers can send an HTTP link, that, when selected by the user, generates an HTTP request to a malicious Web site. In your logs, the destination IP address for the event can be the malicious Web site; however, some foreign Web sites can also trigger this signature, creating a false positive.
