A disaster recovery approach should include which of the following elements?

Question

BlackTom AI · Accepted Answer

When considering components of a disaster recovery approach, we examine which elements support restoring operations after an incident.
Option 1: Firewalls. While firewalls are important for limiting unauthorized access and protecting systems during normal operations, they are not a core disaster recovery control that directly enables restoration of services after a disruption. They’re more about preventive security than recovery in the aftermath.
Option 2: Regular backups. Backups are a fundamental disaster recovery element because they provide the data copies needed to restore systems to a known good state after loss or corruption. Without backups, recovery of data and continuity of operations becomes uncertain or impossible.
Option 3: Encryption. Encryption protects sensitive data at rest and in transit, which is crucial for confidentiality and data security, but it does not by itself enable restoration or continuity after a disaster. It’s a protective measure rather than a recovery mechanism.
Option 4: Surge protectors. Surge protection helps guard hardware against power surges, reducing physical damage risk. However, they do not facilitate the restoration of systems or data after an incident and are more about hardware protection than recovery planning.
In summary, among the listed elements, regular backups directly support the ability to recover and continue operations following a disaster, whereas the other items serve preventive or protective roles that do not address the recovery process themselves.
