Privilege escalation is the act of exploiting a bug , a design flaw , or a configuration oversight in an operating system or software application to gain ...
A number of computer operating systems employ security features to help prevent malicious software from gaining sufficient privileges to compromise the computer system. .

Learning the policies, procedures, and traditions of English Wikipedia is a gradual process, and many editors with an intermediate level of experience will have at least some of the skill set necessary to being a good Wikipedia administrator.
