Security Administrator's Integrated Network Tool
Jump to user comments
networking, security, tool (SAINT, originally "Security
Administrator Tool for Analyzing Networks", SATAN) A tool
written by Dan Farmer and Wietse Venema which remotely probes
systems via the network and stores its findings in a
database. The results can be viewed with an web browser.
SAINT requires Perl 5.000 or better.
In its simplest mode, SAINT gathers as much information about
remote hosts and networks as possible by examining such
network services as finger, NFS, NIS, FTP, TFTP,
rexd, and other services. The information gathered includes
the presence of various network information services as well
as potential security flaws - usually in the form of
incorrectly setup or configured network services, well-known
bugs in system or network utilities, or poor or ignorant
policy decisions. It can then either report on this data or
use a simple rule-based system to investigate any potential
security problems. Users can then examine, query, and analyze
the output with a web browser. While the program is
primarily geared toward analysing the security implications
of the results, a great deal of general network information
can be gained when using the tool - network topology, network
services running, and types of hardware and software being
used on the network.
SAINT can also be used in exploratory mode. Based on the
initial data collection and a user configurable ruleset, it
will examine the avenues of trust and dependency and iterate
further data collection runs over secondary hosts. This not
only allows the user to analyse his own network, but also to
examine the real implications inherent in network trust and
services and help them make reasonably educated decisions
about the security level of the systems involved.
