-Access control refers to controlling access by a user to a computer system, or data on that system. In formal terms, a &quot;subject&quot; (e.g. a user) attempts to access the &quot;object&quot; (e.g. system or data). An access control system will evaluate the security levels of the subject and object in order to see if access is permitted. Example: A simple example is the case where you enter a username and password in order to log onto the computer. Contrast: mandatory access control The system gives users &quot;clearance levels&quot;, and assigns sensitivity levels to information. Therefore, if you only have &quot;secret&quot; clearance level, you cannot access &quot;top-secret&quot; information, but you can access &quot;secret&quot; or &quot;confidential&quot; information. See: Bell-LaPadula Model for more information. discretionary access control This system assigns subjects (users) to one or more groups. An object (system or file) contains a DACL (discretionary access control list) enumeration which users and groups may access the object. See: Access Control List for more information. Key point: There are different kinds of access. Read access means that somebody can read information, whereas write access implies that that somebody can change the data. For example, you can get a copy of your credit report and read it, but you can&apos;t necessarily change the data. From Hacking-Lexicon
