CISSP Exam Note (Domain 2: Telecommunications and Networking Security) – Back-up Methodologies

December 2, 2009 · Posted in Information Security, Information Systems · Comment 

In information technology, a backup or the process of backing up refer to making copies of data so that these additional copies may be used to restore the original after a data loss event. These additional copies are typically called “backups.” The verb is back up in two words, whereas the noun is backup (often used like an adjective in compound nouns).

Backups are useful primarily for two purposes. The first is to restore a state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Data loss is also very common. 66% of internet users have suffered from serious data loss.

    • CVE-2012-1601 (linux_kernel) May 16, 2012
      The KVM implementation in the Linux kernel before 3.3.6 allows host OS users to cause a denial of service (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU already exists. […]
      nvd@nist.gov
    • CVE-2011-4621 (linux_kernel) May 16, 2012
      The Linux kernel before 2.6.37 does not properly implement a certain clock-update optimization, which allows local users to cause a denial of service (system hang) via an application that executes code in a loop. […]
