ITPEC IP October 2021 Question 38
ITPEC IP October 2021 — Question 38 of 100
Installing antivirus software and applying security patches are both appropriate virus-infection countermeasures, so A and B are correct. Antivirus can detect or block malicious code, while patches close vulnerabilities that malware could exploit.
Answer (a)
Why not others:
- a hard-disk password restricts access to the disk but does not detect or prevent virus execution
- file encryption protects confidentiality but does not stop a virus from infecting the system
Key rule: Prevent malware with current detection tools and timely vulnerability remediation; access and confidentiality controls solve different risks.
