Question

BlackTom AI · Accepted Answer

Protecting systems and data from cyber threats and unauthorised access is the core purpose of cybersecurity.

1. Relevant knowledge points and concepts
- CIA triad: Confidentiality (preventing unauthorised data disclosure), Integrity (ensuring data is accurate and unaltered), Availability (systems remain accessible to legitimate users). 
- Authentication and access control: verifying identities and assigning permissions. 
- Encryption, firewalls, intrusion detection/prevention, endpoint protection, patch management, incident response and risk assessment are common technical measures. 
- Policies, user training, and compliance are non-technical components that support security.

2. Step-by-step reasoning process
- Compare each answer option to the CIA triad and common cybersecurity goals.
- Determine whether the described activity aims at preventing, detecting or responding to cyber threats, or instead addresses unrelated disciplines (UX, marketing, resource quotas).

3. Intermediate steps (analysis of options)
- Option 1: Improving user interface design to reduce unwanted usage — relates to user experience (UX) and usability, not primarily to protecting systems or data. While better UX can influence security behaviour, it is not the main focus of cybersecurity.
- Option 2: Increasing website traffic using protected gateways — concerns marketing/SEO and traffic growth; protected gateways might be security-related but the objective (increasing traffic) is not a cybersecurity goal.
- Option 3: Maintaining cloud storage quotas for authorized users — is systems administration or resource management; it’s operational but not primarily about defending against threats.
- Option 4: Protecting systems and data from cyber threats and unauthorised access — directly matches confidentiality, integrity and availability goals and encompasses technical and policy controls listed above.

4. Why the correct answer is correct
Option 4 explicitly states defence against cyber threats and unauthorised access, which is the central objective of cybersecurity. All typical cybersecurity tools and processes (encryption, access control, incident response) serve this purpose.

5. Why the other options are incorrect (brief)
- Option 1: UX/design focus, not primary security function.
- Option 2: Marketing objective; increasing traffic is not a security aim.
- Option 3: Resource quota management, an administrative task distinct from threat protection.

6. Conclusion
The correct answer is "Protecting systems and data from cyber threats and unauthorised access," which matches the provided answer.
