==== 1. In Focus: Supercharging Snort === by Mark Joseph Edwards, News Editor, mark at ntsecurity / net
Certainly you've heard of the open-source Intrusion Detection
System/Intrusion Prevention System (IDS/IPS) Snort. Maybe you're one of
the countless people who use it. If so, you know it's a great tool with
a huge amount of support from the user community. You might also know
that Sourcefire, the company behind Snort, offers a commercial version
of Snort and other network-protection tools. When I recently visited
the Snort.org Web site, I learned that you can now subscribe to the
Sourcefire Vulnerability Research Team's certified rulesets, which
means that you can receive the latest rulesets five days sooner than
those rulesets are released to the general public.
Maybe you write your own rules in addition to using rulesets available
at the Snort Web site. As with the source code for any application, the
way a rule is written affects the performance of Snort. Poorly written
rules take more time to process. A few extra microseconds of processing
time here and there might not seem like a big deal, but when you
consider an overall traffic load, those microseconds add up to full
seconds really fast, and of course those seconds add up to minutes. The
more efficient your rules, the more efficiently your IDS runs and the
less likely that some sort of anomalous traffic-dropping occurs.
So how can you determine how efficient your rules are? An easy way is
to use the new TurboSnortRules online benchmarking tool, sponsored by
VigilantMinds. TurboSnortRules is a Web-based service that lets you
enter a rule and test its performance on various versions of Snort
against a set of control data. The test output shows you how fast your
rule operates on those selected versions.
As an example of how effective the service can be, take a look at the
two sets of test results listed at the URLs below. Both tested rules
are designed to detect Yahoo! Messenger logons. As you'll see in the
results, one rule operates much faster than the other.
For another example, look at the two sets of test results for rules
designed to detect the Mytob Trojan horse (at the first two URLs
below). One rule operates faster than the other, but in this case, the
difference in speed isn't as dramatic as in the comparison of the
Yahoo! Messenger rules. Even so, every little bit of speed improvement
helps. One slow rule could cause Snort to begin dropping packets, which
could jeopardize your overall security. See the third URL below too,
which graphically illustrates the damage one poorly written rule can
Also at the TurboSnortRules site, you'll find a searchable database for
looking up rules that are either part of the Snort distribution or that
have been submitted to the site by administrators for testing. The
database is a good way to find rules you might need but don't want to
write yourself, and the related performance data shows you how well
those rules perform. Another excellent resource at the site is the
Snort Performance Wiki, which has a lot of useful suggestions about how
to make Snort run as fast as possible.

IIS 6.0 Enhancements in Windows 2003 SP1
Although most of the major Windows Server 2003 Service Pack 1 (SP1)
changes concentrate on the core OS, SP1 doesn't neglect Microsoft IIS.

the Web server application that's bundled with Windows 2003. Michael
Otey outlines those changes in this brief summary on our Web site.
