  2. Principle of least privilege - Wikipedia

    en.wikipedia.org/wiki/Principle_of_least_privilege

    In information security, computer science, and other fields, the principle of least privilege (PoLP), also known as the principle of minimal privilege (PoMP) or the principle of least authority (PoLA), requires that in a particular abstraction layer of a computing environment, every module (such as a process, a user, or a program, depending on the subject) must be able to access only the ...

    en.wikipedia.org/wiki/The_Protection_of...

    Separation of privilege: Where feasible, a protection mechanism that requires two keys to unlock it is more robust and flexible than one that allows access to the presenter of only a single key. Least privilege: Every program and every user of the system should operate using the least set of privileges necessary to complete the job.

  4. Privilege separation - Wikipedia

    en.wikipedia.org/wiki/Privilege_separation

    A common method to implement privilege separation is to have a computer program fork into two processes. The main program drops privileges, and the smaller program keeps privileges in order to perform a certain task. The two halves then communicate via a socket pair. Thus, any successful attack against the larger program will gain minimal ...

  5. Protection ring - Wikipedia

    en.wikipedia.org/wiki/Protection_ring

    Most modern operating systems use level 0 for the kernel/executive, and use level 3 for application programs. Any resource available to level n is also available to levels 0 to n, so the privilege levels are rings. When a lesser privileged process tries to access a higher privileged process, a general protection fault exception is reported to ...

  6. Privilege (computing) - Wikipedia

    en.wikipedia.org/wiki/Privilege_(computing)

    In computing, privilege is defined as the delegation of authority to perform security-relevant functions on a computer system. [1] A privilege allows a user to perform an action with security consequences. Examples of various privileges include the ability to create a new user, install software, or change kernel functions.

    en.wikipedia.org/wiki/Comparison_of_privilege...

    Normally, applications use system.privilege.admin, but another may be used, such as a lower right for security, or a higher right if higher access is needed. If the right the application has is not suitable for a task, the application may need to authenticate again to increase the privilege level.

    Dasgupta recommends avoiding large meals, caffeine, and alcohol at least 3 hours before turning in to prevent disruptions to your rest. “All of these can interfere with your ability to fall and ...

  9. Privilege revocation (computing) - Wikipedia

    en.wikipedia.org/wiki/Privilege_revocation...

    Honoring the Principle of least privilege at a granularity provided by the base system such as sandboxing of (to that point successful) attacks to an unprivileged user account helps in reliability of computing services provided by the system. As the chances of restarting such a process are better, and other services on the same machine aren't ...
