How Secure is Your Network? LANGuard 1.25
Seven network scanners test your security before the crackers do.
- By Greg Saoutine
LANguard is a fast, basic scanner that performs port
scans (based on ports defined in its configuration text
file, which can be edited by the user), brute force
attacks (based on a password text file and character
sets), user enumeration and other tasks. In one to two
minutes, LANguard was able to collect a fair amount
of information about the test system, all of which was
correct. The software doesn't report on "vulnerabilities,"
but produces a list of users enumerated through a NetBIOS
NULL session and information obtained via SNMP queries,
as shown in the figure.
|LANguard provides information in a
treeview format. This makes it easy to drill down
on the exact security areas you’re most concerned
about. (Click image to view larger version.)
For a basic scan of "interesting" ports, password brute
force attack and information gathering, LANguard performs
the same as any commercial tool. However, lack of vulnerability
checking and attack-simulation capabilities limits its
ability to provide a comprehensive security assessment
of the target host.
