Asset (computer security)
In information security, computer security and network security an Asset is any data, device, or other component of the environment that supports information-related activities. Assets generally include hardware (e.g. servers and switches), software (e.g. mission critical applications and support systems) and confidential information.〔(ISO/IEC 13335-1:2004 Information technology -- Security techniques -- Management of information and communications technology security -- Part 1: Concepts and models for information and communications technology security management )〕〔(ENISA Glossary )〕 Assets should be protected from illicit access, use, disclosure, alteration, destruction, and/or theft, resulting in loss to the organization.〔("An Introduction to Factor Analysis of Information Risk (FAIR)", Risk Management Insight LLC, November 2006 );〕

The goal of Information Security is to ensure the Confidentiality, Integrity and Availability of assets from various threats. For example, a hacker might attack a system in order to steal credit card numbers by exploiting a vulnerability. Information Security experts must assess the likely impact of an attack and employ appropriate countermeasures.〔IETF RFC 2828〕 In this case they might put up a firewall and encrypt their credit card numbers.
