100-160 Question 115
Single answerA cybersecurity technician is tasked with securing a company's workstations that run various operating systems. One of the steps involves ensuring that only authorized applications can run on these systems. Which operating system security concept should the technician implement to achieve this goal?
- A
Application whitelisting
- B
Antivirus scanning
- C
Data Loss Prevention (DLP)
- D
Disk encryption
Show answer and explanation
Correct answer: A
Explanation
Application whitelisting is a critical operating system security concept that helps prevent unauthorized applications, including malware, from running on workstations. This method ensures that only explicitly allowed applications, as defined in a whitelist, can execute, improving the overall security posture of the operating system.
- A. Correct.
Application whitelisting is a security concept that ensures only pre-approved and authorized applications can run on a system, effectively preventing unauthorized or malicious applications from executing.
- B. Incorrect.
Antivirus scanning is a security measure that detects and removes malicious software but does not inherently control which applications are allowed to run.
- C. Incorrect.
Data Loss Prevention (DLP) focuses on preventing sensitive data from being leaked or transmitted outside of authorized channels and is unrelated to controlling application execution.
- D. Incorrect.
Disk encryption is used to secure data on a storage device by encrypting it, but it does not control which applications can be executed on the system.
