       What is a Vulnerability Assessment
       (VA)?


 Evaluates     weaknesses to threats
 Considers     risks to water system and community
 Provides framework for risk reduction options
  and cost considerations
 Prioritizes   corrective actions

Using the VA Tool
                                                     Identification/Prioritization of Adverse

Experts
 Local/State/Federal                                Determine Acts that Could Result in

                    Six Basic Elements of VAs

1.       Characterize water system
     •     Identify customers
     •     Facilities, processes, assets important to mission
2.       Identify & prioritize adverse consequences to
         avoid
     •     Identify impacts that could disrupt safe & reliable
           water supply or affect public health
     •     Define range of impacts for each event



                                                                 5
                Six Basic Elements of VAs (cont’d)

3.       Determine critical
         assets subject to attack
     •     Review assets defined by
           Bioterrorism Response
           Act of 2002 (PL 107-188)
4.       Assess likelihood of
         malicious attack
     •     Determine possible

5.       Evaluate existing countermeasures
     •     What are capabilities to detect, delay, respond?
     •     Cyber system protection features?
     •     Security policy & procedures -- Compliance record?
6.       Analyze current risk and develop prioritized
         plan for risk reduction

          General Strategies for Reducing
          Vulnerabilities

 Sound   business practices
 System   upgrades
 Security   upgrades
