What is the principle of least privilege in DIS technology?
Answer: Users get only the minimum access needed for their role
Least privilege limits access to only what is needed, reducing potential damage from errors or compromised accounts.
What is backup and disaster recovery for in DIS technology?
Answer: Ensuring data restoration and operations resumption after failures
These plans ensure critical data and systems can be restored within acceptable timeframes after disruptions.
What is multi-factor authentication in DIS security?
Answer: Requiring two or more verification factors for access
MFA requires multiple verification factors (knowledge, possession, biometrics), significantly reducing unauthorized access.
What is change management in DIS technology?
Answer: A structured process for evaluating and implementing changes safely
IT change management ensures changes are evaluated, approved, tested, and implemented in a controlled manner.
What is an SLA in DIS technology?
Answer: A formal agreement defining expected service performance standards
An SLA defines measurable performance standards between provider and client, with consequences for failure.
Why is documentation important in DIS technology?
Answer: It ensures knowledge transfer, troubleshooting, and operational continuity
Documentation captures configurations and procedures, enabling knowledge transfer and continuity regardless of staff changes.
