Which of the following is NOT a factor related to Access Control?

  1. integrity
  2. authenticity
  3. confidentiality
  4. availability

Answer(s): B

Explanation:

These factors cover the integrity, confidentiality, and availability components of information system security.
Integrity is important in access control as it relates to ensuring only authorized subjects can make changes to objects.
Authenticity is different from authentication. Authenticity pertains to something being authentic, not necessarily having a direct correlation to access control.
Confidentiality is pertinent to access control in that the access to sensitive information is controlled to protect confidentiality.
vailability is protected by access controls in that if an attacket attempts to disrupt availability they would first need access.

Which of the following is most appropriate to notify an external user that session monitoring is being conducted?

  1. Logon Banners
  2. Wall poster
  3. Employee Handbook
  4. Written agreement

Answer(s): A

Explanation:

Banners at the log-on time should be used to notify external users of any monitoring that is being conducted. A good banner will give you a better legal stand and also makes it obvious the user was warned about who should access the system and if it is an unauthorized user then he is fully aware of trespassing.
This is a tricky question, the keyword in the question is External user.
There are two possible answers based on how the question is presented, this question could either apply to internal users or ANY anonymous user.
Internal users should always have a written agreement first, then logon banners serve as a constant reminder.
Anonymous users, such as those logging into a web site, ftp server or even a mail server; their only notification system is the use of a logon banner.

Which of the following pairings uses technology to enforce access control policies?

  1. Preventive/Administrative
  2. Preventive/Technical
  3. Preventive/Physical
  4. Detective/Administrative

Answer(s): B

Explanation:

The preventive/technical pairing uses technology to enforce access control policies.
TECHNICAL CONTROLS
Technical security involves the use of safeguards incorporated in computer hardware, operations or applications software, communications hardware and software, and related devices. Technical controls are sometimes referred to as logical controls.
Preventive Technical Controls
Preventive technical controls are used to prevent unauthorized personnel or programs from gaining remote access to computing resources. Examples of these controls include:
Access control software.
Antivirus software.
Library control systems.
Passwords.
Smart cards.
Encryption.
Dial-up access control and callback systems.
Preventive Physical Controls
Preventive physical controls are employed to prevent unauthorized personnel from entering computing facilities (i.e., locations housing computing resources, supporting utilities, computer hard copy, and input data media) and to help protect against natural disasters. Examples of these controls include:
Backup files and documentation.
Fences.
Security guards.
Badge systems.
Double door systems.
Locks and keys.
Backup power.
Biometric access controls.
Site selection.
Fire extinguishers.
Preventive Administrative Controls
Preventive administrative controls are personnel-oriented techniques for controlling people's behavior to ensure the confidentiality, integrity, and availability of computing data and programs. Examples of preventive administrative controls include:
Security awareness and technical training.
Separation of duties.
Procedures for recruiting and terminating employees.
Security policies and procedures.
Supervision.
Disaster recovery, contingency, and emergency plans.
User registration for computer access.

Access control is the collection of mechanisms that permits managers of a system to exercise a directing or restraining influence over the behavior, use, and content of a system. It does not permit management to:

  1. specify what users can do
  2. specify which resources they can access
  3. specify how to restrain hackers
  4. specify what operations they can perform on a system.

Answer(s): C

Explanation:

Access control is the collection of mechanisms that permits managers of a system to exercise a directing or restraining influence over the behavior, use, and content of a system. It permits management to specify what users can do, which resources they can access, and what operations they can perform on a system. Specifying HOW to restrain hackers is not directly linked to access control.
