The Issue of “Integrity Drift”
   Confidence degrades the minute you go live or “plug in”
   Trust erodes after:
    Applications are installed
    Patches are applied
    Machines are subjected to constant use, change and routine maintenance
   Recovery means reformatting and rebuilding from scratch
   Potential loss is unbounded (and often unknown)
             100%
                    Confidence




                                    Time
Tripwire Prevents “Integrity Drift”
   Confidence is maintained even as your system changes
   Remediation is as simple as restoring systems to the last
    known good state

      How Does Tripwire Work?
1. Take digital snapshot
     of existing files             2. Take a second digital
                                    snapshot later in time
                                         to compare




     3. Any integrity
violations are reported

Tripwire applications:
Data Security/Intrusion Detection
Problem:
  “$2.7 M is the average cost of an authorized user attack,
  according to the FBI. In fact, internal and authorized users –
  your employees, partners and consultants – commit 75-85% of
  computer crime.”
Solution:
  Tripwire detects all unauthorized change whether it be from an
  outside intruder or within your organization.

The only way you can know, for sure, when your
systems have been compromised.
Tripwire applications:
Damage Assessment and Remediation
Problem:
  “…Close to 30% of companies indicated they would not be
  aware that their core business information had been altered until
  12 to 24 hours later and roughly 30% would not be aware of a
  compromise for more than 2 days.”
       Source: CIO Magazine

Solution:
  Tripwire pinpoints exact areas of change and damage, enabling
  immediate, efficient remediation.
 Outage costs can be as high as $25,000/minute. How
 quickly can you discover changes to your systems?
Tripwire applications:
System Lock-down
Problem: Integrity Drift!
  At the point you are 100% confident in the state of your systems,
  you need to lock them down and ensure that nothing changes
  unless you want it to.
Solution:
  Tripwire confirms the lock down of your systems by taking a
  baseline inventory of all your data assets and providing
  immediate visibility into any deviations from that baseline
  snapshot.
Tripwire applications:
Change/Configuration Management
Problem:
  Change control processes are only as good as your ability to
  monitor and validate those processes.
  99% of all trouble tickets are the result of authorized individuals making
  unauthorized or inappropriate changes

Solution:
  Tripwire provides visibility across an organization’s data center,
  identifying all changes – authorized or unauthorized.
  Verifies that work orders have been properly deployed across all
  machines. Allows you to map all changes back to the original work order
Tripwire applications:
Industry Regulation and Policy Compliance

Problem:
  New industry regulations require significant changes in current
  business practices. Companies not in compliance risk stiff
  penalties and/or a significant loss of business.

   I’m worried if we’re hit by the newest virus or worm my antivirus
    software may not detect it.
   I have the perimeter solved. Do we need anything else?
   My systems change constantly, but I can’t track the changes and
    don’t know which ones to act on first.
   Discovering the cause of system problems is a long, trial-and-
    error process.
   I need to make strong recommendations that other people trust.
   I need to ensure tamperproof security solutions (no one can
    cover up their tracks or get around them)
   In the past, we’ve bought products then had trouble finding staff
    who are familiar with them
