What is TripWire?
  • Reliable intrusion detection system.
  • Tool that checks to see what changes have been
    made in your system.
  • Pinpoints, notifies, determines the nature, and
    provides information on the changes on how to
    manage the change.
  • Mainly monitors the key attributes(like binary
    signature, size and other related data) of your
    files.
  • Changes are compared to the established good
    baseline.
  • Security is compromised, if there is no control
    over the various operations taking place.
  • Security not only means protecting your system
    against various attacks but also means taking
    quick and decisive actions when your system is
    attacked.

How does TripWire work?
5
  • First, a baseline database is created storing the
    original attributes like binary values in
    registry.
  • If the host computer is intruded, the intruder
    changes these values to go undetected.
  • The TripWire software constantly checks the
    system logs to check if any unauthorized changes
    were made.
  • If so, then it reports to the user.
  • User can then undo those changes to revert the
    system back to the original state.

6
Where is TripWire used?
  • Tripwire for Servers(TS) is software used by
    servers.
  • Can be installed on any server that needs to be
    monitored for any changes.
  • Typical servers include mail servers, web
    servers, firewalls, transaction server,
    development server.
  • It is also used for Host Based Intrusion
    Detection System(HIDS) and also for Network
    Intrusion Detection System(NIDS).
  • It is used for network devices like routers,
    switches, firewall, etc.
  • If any of these devices are tampered with, it can
    lead to huge losses for the Organization that
    supports the network.

7
How do you install and use TripWire?
  • Install Tripwire and customize the policy file.
  • Initialize the Tripwire database.
  • Run a Tripwire integrity check.
  • Examine the Tripwire report file.
  • Take appropriate security measures.
  • Update the Tripwire database file.
  • Update the Tripwire policy file.

8
What is the benefit of TripWire?
  • Increase security
  • Immediately detects and pinpoints unauthorized
    change.
  • Instill Accountability
  • Tripwire identifies and reports the sources of
    change.
  • Gain Visibility
  • Tripwire software provides a centralized view of
    changes across the enterprise infrastructure and
    supports multiple devices from multiple vendors.
  • Ensure Availability
  • Tripwire software reduces troubleshooting time,
    enabling rapid discovery and recovery. Enables
    the fastest possible restoration back to a
    desired, good state.
