CyberSecurity Fundamentals (Section 1,5 And 6)
Cyber security is the practice of ensuring the integrity, confidentiality, and availability of information. It helps prevent dangerous accidents like hard drive failures or power outages, and from attacks by adversaries. If you are planning to get the certificate from Nexus on cyber security the quiz below will help with your revision of section 1,5 and 6.

Three common controls used to protect the availability of information are:
- A.
A. Redundancy, backups and access controls.
- B.
B. Encryption, file permissions and access controls.
- C.
C. Access controls, logging and digital signatures.
- D.
D. Hashes, logging and backups.
Correct Answer
A. A. Redundancy, backups and access controls.Explanation
The correct answer is a. Redundancy, backups and access controls. These three controls are commonly used to protect the availability of information. Redundancy ensures that there are multiple copies or backups of the information, so that if one copy is unavailable, another copy can be used. Backups involve regularly creating copies of the information and storing them in a secure location, so that if the original data is lost or damaged, it can be restored from the backups. Access controls restrict who can access the information, ensuring that only authorized individuals have access to it. Together, these controls help to ensure that information is available when needed.Rate this question:
