Disaster Recovery and Incident Response Flashcards
cold site
A physical site that can be used if the main site is inaccessible but that lacks all of the resources necessary to get business functionality immediately; 1-2 weeks necessary to reach full functionality
differential backup
Type of backup that backs up all new or changed files since the last full backup; does not reset the archive bit
disaster recovery
The act of recovering data following a disaster in which it has been destroyed
disaster-recovery plan
A plan outlining the procedure by which data is recovered after a disaster
failover
The process of reconstructing a system or switching over to other systems when a failure is detected
forensics
The act of looking at all the data at your disposal to try to figure out who gained unauthorized access and the extent of that access
full backup
A backup that copies all data to the archive medium; resets the archive bit
hot site
A location that can provide operations within hours of failure
incremental backup
A type of backup that includes only new or changed files since the last full backup or incremental backup; resets the archive bit
intrusion
The act of entering a system without authorization to do so
intrusive tests
Penetration-type testing that involves trying to break into the network
nonintrusive tests
Penetration/vulnerability testing that takes a passive approach
