Understanding Logical Data Protection

What is the primary purpose of tiered levels of access to data?

• To increase data storage capacity

• To ensure that only authorised users can access certain data

• To speed up data processing

• To reduce data redundancy

Which of the following is a type of logical protection that acts as a barrier between a trusted network and an untrusted network?

• Obfuscation

• Firewall

• Encryption

• Password protection

What is the main function of anti-malware applications?

• To encrypt data

• To detect and remove malicious software

• To manage user access levels

• To compress files

Which logical protection method involves making data unreadable to unauthorised users by transforming it into a different format?

• Firewall

• Obfuscation

• Password protection

• Data compression

What is the purpose of encrypting data at rest?

• To prevent data loss during transmission

• To protect data stored on devices from unauthorised access

• To increase data transfer speed

• To reduce storage space

Which of the following ensures the security of data while it is being transmitted over a network?

• Data compression

• Encryption of data in transit

• Firewall

• Obfuscation

What is the role of password protection in logical security?

• To encrypt data

• To authenticate users and control access to systems

• To increase network speed

• To backup data

Which of the following is NOT a logical protection method?

• Firewall

• Anti-malware applications

• Physical locks

• Encryption

What is the benefit of using a hardware firewall over a software firewall?

• It is cheaper

• It provides better protection against physical theft

• It can handle more traffic and is generally more robust

• It is easier to configure

Which of the following is a common method to obfuscate data?

• Using complex algorithms to encrypt data

• Scrambling data to make it unreadable without a key

• Compressing data to save space

• Backing up data to a secure location
