Final answer:
The detailed steps necessary for implementing access controls and a disaster recovery plan involve setting up user roles, permissions, and authentication methods, and developing a strategy for maintaining business functions and data recovery post-disaster.
Step-by-step explanation:
The detailed steps needed to carry out access controls, a disaster recovery plan are option d.
To implement access controls, an organization must first identify resources that require protection. This involves establishing user identities and defining roles that determine the extent of access each user has. Administrators then use these roles to set permissions on systems and data. Methods of authentication are deployed, such as passwords, biometrics, or two-factor authentication to verify user identities. Regular auditing and monitoring of access should also be enforced to ensure adherence to the policies and prevent unauthorized use.
Developing a disaster recovery plan involves an assessment of critical business functions and the resources they require, followed by the identification and prioritization of potential risks. A strategy must be established to maintain operations and recover lost data in the event of a disaster. This includes the implementation of data backups, establishing alternate work sites, and ensuring the availability of necessary hardware and software. Regular testing and updating of the disaster recovery plan are essential to ensure its effectiveness during an actual emergency.
