Intrusion
Detection is the early warning when your site is under attack
which also logs the details for use in tracking down the
perpetrator. Intrusion Detection Systems (IDS) are either
network-based (NIDS), which passively watches traffic as it
traverses your network, or host-based (HIDS) which monitors
traffic arriving at individual hosts as well as their logfiles.
NIDS
and HIDS complement proactive security elements such as
firewalls, host hardening, and anti-virus software, and
there's even an emerging breed of Intrusion Prevention Systems
which control the behavior of applications on workstations and
servers.
While IDS
software is fairly simple to get up and running, installation
is only the tip of the iceberg. In order to be effective, the
placement of sensors is critical: how many and where should
they be placed to ensure adequate coverage but avoid redundant
or excessive alerts and white noise? What signatures should be
enabled for your environment and what custom signatures need
to be created? How should alerts and reports be configured to
avoid losing important data in a sea of false positives or
throwing out the proverbial baby with the bath water? A full
80% of IDS deployment is planning and tuning.
At NOIT Group,
our technicians keep up-to-date on current security
vulnerabilities and zero-day exploits. Our core proficiency is
in all practical facets of IP networking, including
architecture design, network performance monitoring and
tuning, identification of infrastructure security and
resiliency weaknesses. We leverage this expertise with IDS
implementation and integration with the rest of your security
architecture to bring you assured vigilance. In planning we'll
even advise you whether you should manage your IDS
infrastructure in-house and when to outsource to a Security
Service Provider (SSP). |
