It enables network administrators to regain and restore operations on a network after going offline, being disconnected, crashing or other events have stopped normal network operations.
Techopedia Explains Network Recovery
Network recovery is primarily done by network administrators or engineers. Reasons for network recovery include, but are not limited to:
- Network hardware problems - Such as router, switch or any other device which has stopped working
- Internet connectivity problems - Network goes offline after Internet, backbone network, leased line or satellite connection is lost
- Network attacks - Network becomes unavailable or goes offline due to any network-based attack such as DoS, DDoS or Ping of Death
- Natural or man-made disaster - Some or all of the major network infrastructure is wiped out in the aftermath of an earthquake, flood, fire or terrorism
Typically network recovery may include:
- Reconfiguring routers, switches, firewalls or other devices
- Installing and deploying new cables, switches and other network components
- Scanning, identifying and removing virus, malware or any other vulnerability
- Restoring computer, server and router OS images from backup
In enterprise networks, network recovery is generally done through a formal network recovery plan.
