Privileges mean what a user is permitted to do. Common privileges including viewing and editing files, or modifying system files.
My part of the project will involve doing privilege escalation do cause havoc in the system
Types of privilege escalation
Vertical privilege escalation, also known as privilege elevation, where a lower privilege user or application accesses functions or content reserved for higher privilege users or applications
Horizontal privilege escalation, where a normal user accesses functions or content reserved for other normal users Mitigation strategies
Operating systems and users can use the following strategies to reduce the risk of privilege escalation:
Data Execution Prevention
Address space layout randomization (to make it harder for buffer overruns to execute privileged instructions at known addresses in memory)
Running applications with least privilege (for example by running Internet Explorer with the Administrator SID disabled in the process token) in order to reduce the ability of buffer overrun exploits to abuse the privileges of an elevated user.
Requiring kernel mode code to be digitally signed.
Use of up-to-date antivirus software
Patching
Use of compilers that trap buffer overruns[9]
Encryption of software and/or firmware components.
If the code in a package runs entirely with privileges equal to or lower than a standard user account, or has no facility for user interaction, this policy is unlikely to apply to it. In practice, packages which provide one or more of:
setuid binaries
PolicyKit policies
consolehelper configurations
udev rules
D-Bus services on the system bus
