For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
Another classification is by the action against the vulnerable system; unauthorized data access, arbitrary code execution, and denial of service are examples. Exploitations are commonly categorized and named [ 9 ] [ 10 ] by the type of vulnerability they exploit (see vulnerabilities for a list) [ clarification needed ] , whether they are local ...
