Administering F-Secure Content Scanner Server
There is a security risk associated with
password protected archives because their
content cannot be inspected without a password
that is known only to the sender and (in most of
the cases) the recipient.
If the recipients do not have any virus protection
on their workstations, or if the virus protection is
not up-to-date, malicious code in a password
protected archive can get through.
Password protected archives are not detected if
scanning inside archives is disabled.
Specify the acceptable unpacked size (in
kilobytes) for archive files. If the unpacked size
of an archive file exceeds this threshold, the
server will consider the archive suspicious and
corresponding action will be taken.
Specify a list of files, separated by spaces, that
are scanned inside archives.
You can also use wildcards (*, ?). To scan all
files, use '*'. To specify files with no extension,
type a dot ('.').
Example: "EXE COM DO? *HTM".
Specify a list of file extensions, separated by
spaces, that are allowed in password protected
archives.
You can also use wildcards: '?' matches exactly
one character, '*' matches any number of
characters, including zero (0) characters.
For example: "DO? *ML".
File extensions are used for recognizing the file
types in password protected archives.
Specify how long a scan task can be carried out
before it is automatically cancelled.
