Cyber security standards have been created recently because sensitive information is now frequently stored on computers that are attached to the Internet. Also many tasks that were once done by hand are carried out by computer; therefore there is a need for Information Assurance (IA) and security. Cyber security is important in order to guard against identity theft. Businesses also have a need for cyber security because they need to protect their trade secrets, proprietary information, and personally identifiable information (PII) of their customers or employees. The government also has the need to secure its information. One of the most widely used security standards today is ISO/IEC 27002 which started in 1995. This standard consists of two basic parts. BS 7799 part 1 and BS 7799part 2 both of which were created by (British Standards Institute) BSI. Recently this standard has become ISO 27001. The National Institute of Standards and Technology (NIST) has released several special publications addressing cyber security. Three of these special papers are very relevant to cyber security: the 800-12 titled “Computer Security Handbook;” 800-14 titled “Generally Accepted Principles and Practices for Securing Information Technology;” and the 800-26 titled “Security Self-Assessment Guide for Information Technology Systems”. The International Society of Automation (ISA) developed cyber security standards for industrial automation control systems (IACS) that are broadly applicable across manufacturing industries. The series of ISA industrial cyber security standards are known as ISA-99 and are being expanded to address new areas of concern.
