What type of control is applied to protect against unauthorized access?

• A. Physical control
• B. Technical control
• C. Administrative control
• D. Deterrent control

Answer: (B)

Technical controls are essential in safeguarding systems against unauthorized access because they involve the use of technology to enforce security policies and protect information systems. These controls can include firewalls, encryption, access control lists, intrusion detection systems, and authentication mechanisms such as passwords and biometrics. By implementing these technological measures, an organization can effectively restrict access to sensitive data and systems to only those individuals who have been granted permission. In contrast, physical controls focus on preventing unauthorized physical access to facilities, like locks, security guards, and surveillance cameras. Administrative controls involve policies and procedures set by the organization to manage security, such as employee training and background checks, but they do not directly involve the technological measures that restrict access. Deterrent controls aim to discourage potential security violations, but they do not actively prevent unauthorized access. Therefore, technical controls are the most direct and effective means of protecting against unauthorized access within information systems.
