Product activation is a license validation procedure required by some proprietary software programs. Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it determines whether it is authorized to fully function. Activation allows the software to stop blocking its use.
The arrow represents a rootkit gaining access to the kernel, and the little gate represents normal privilege elevation, where the user has to enter an Administrator username and password. 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. . Operating systems lacking such features, such as DOS, Windows implementations prior to Windows NT (and its descendants), CP/M-80, and all Mac operating systems prior to Mac OS X, had only one category of user who was allowed ...
chkrootkit (Check Rootkit) is a Unix-based program intended to help system administrators check their system for known rootkits.It is a shell script using common UNIX/Linux tools like the strings and grep commands to search core system programs for signatures and for comparing a traversal of the /proc filesystem with the output of the ps (process status) command to look for discrepancies.
