Document Summary
The key features of a security system are accountability, authentication and password, authorization and access control, availability, data integrity, data storage, data transmission, parameter definition, and rule-limit access. Accountability is that users are responsible for user access to information and their actions can be traced based on their audit trails. An audit trail is a log of security relevant records such as financial transactions, scientific research, and health care data transactions. Authentication is gaining access to a secure system by biometric or physical devices. Different levels of access dependant o predefined users. Availability is up to date information that is accurate. Data integrity ensures that data has not been altered or destroyed in an unauthorized manner. Data storage is physical protection and storage of equipment such as server room. Data transmission is the exchange of data by encryption or firewall. Parameter definition is when a system has defined boundaries for users.
