The following table <br />shows recent VA projects FNI has completed. <br /> <br /> <br />1. Determination of water system objectives by: <br />· Identifying the important missions/functions of <br />the system to be assessed <br />· Identifying the undesirable consequences that <br />could affect the missions/functions <br />· Determining the assets that need to be pro- /' /' /' /' <br />tected to minimize the impacts of the undesir- V V V V <br />able events/consequences <br />. Determining the malevolent acts that could <br />reasonably cause these events/consequences <br /> <br />2. Prioritization of adverse events/consequences <br />affecting the water system and the surrounding <br />community including: <br />· Loss of critical function and/or major service <br />disruption <br />· Intentional attack on public safety via water <br />util ity assets, contamination of the water <br />supply, and chemical releases or chemical <br />theft <br /> <br />./ <br /> <br />././ <br /> <br />3. Definition of how the malevolent acts might be <br />conducted, such as: <br />· Physical damage <br />· Chemical, biological and radiological con- <br />tamination <br />. Cyber attacks on the Supervisory Control and <br />Data Acquisition (SCADA) or other process <br />control systems <br />· Interdependency disruptions (e.g., electrical, <br />transportation, etc.) <br /> <br />./ <br /> <br />././ <br /> <br />VlIlnerabilil}' A,;"e"smenl and Emergency Re"pon.;e Plan SOQ <br /> <br />page 7 3 <br />
