    True or False? For identification to be useful, it is sufficient for each identity to be recognizable to the system.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    For identification to be useful, it is not sufficient for each identity to be recognizable to the system. In addition to being recognizable, the system should also be able to differentiate between different identities and assign them accurately. Simply recognizing identities without proper differentiation can lead to confusion and incorrect identification. Therefore, the statement "For identification to be useful, it is sufficient for each identity to be recognizable to the system" is false.

    Rate this question:

  • 11. 

    What are one or more methods used to authenticate identity?

    • A.

      Something you have

    • B.

      Something you do

    • C.

      Something you are

    • D.

      Something you know

    Correct Answer(s)
    A. Something you have
    C. Something you are
    D. Something you know
    Explanation
    The methods used to authenticate identity include "Something you have," which refers to possessing a physical item like an ID card or a key; "Something you are," which involves biometric traits like fingerprints or facial recognition; and "Something you know," which requires knowledge of a password or PIN. These methods provide multiple layers of security to ensure the accurate identification of an individual.

    Rate this question:

  • 12. 

    Which one of the following authentication methods is necessary to safeguard systems and facilities in high-security environments?

    • A.

      A token

    • B.

      A PIN

    • C.

      Biometrics

    • D.

      Strong/two-factor authentication

    Correct Answer
    D. Strong/two-factor authentication
    Explanation
    Strong/two-factor authentication is necessary to safeguard systems and facilities in high-security environments because it adds an extra layer of security by requiring users to provide two different forms of identification. This can include a combination of something the user knows (such as a PIN) and something the user possesses (such as a token or biometric data). By requiring two factors of authentication, it becomes much more difficult for unauthorized individuals to gain access to sensitive information or restricted areas, enhancing the overall security of the environment.

    Rate this question:

  • 13. 

    Though single sign-on can be convenient, what is a potential security problem?

    • A.

    • B.

      It can allow hackers through the firewall.

    • C.

      It can allow an unauthenticated user access to secure facilities.

    • D.

      If you forget your user ID and password, you will not have access to any systems.

    Correct Answer
    A. It can allow an unauthenticated user access to all systems.
    Explanation
    Single sign-on (SSO) is a system that allows users to access multiple applications or systems with a single set of login credentials. While SSO offers convenience, it also poses a potential security problem. By providing access to all systems with just one login, SSO can allow an unauthenticated user to gain access to sensitive information or resources without proper authentication. This can lead to unauthorized access, data breaches, and compromise of secure facilities.

      Guess a password through a brute force process.

    Correct Answer
    C. Capture a user ID and steal a password.
    Explanation
    The simplest way to attack an access control system is to capture a user ID and steal a password. This method involves obtaining someone's login credentials, either by physically stealing them or through techniques like phishing or keylogging. By doing so, an attacker can gain unauthorized access to the system by impersonating the legitimate user. This method is considered simple because it relies on exploiting human vulnerabilities rather than technical weaknesses in the system itself.

    Rate this question:

  • 16. 

    An attack where an attacker pretends to be someone else to hide his or her actual identity is known as:

    • A.

      Spoofing.

    • B.

      Shoulder surfing.

    • C.

      Theft.

    • D.

      Guessing.

    Correct Answer
    A. Spoofing.
    Explanation
    Spoofing is the correct answer because it refers to the act of an attacker pretending to be someone else to conceal their true identity. This is commonly done through techniques such as IP spoofing, email spoofing, or caller ID spoofing. By impersonating someone else, the attacker can deceive and manipulate victims into providing sensitive information or gaining unauthorized access to systems or networks. Shoulder surfing, theft, and guessing are not specific to hiding one's identity and do not involve impersonation.

    Rate this question:

  • 17. 

    True or False? The audit function is the principal function for monitoring access.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    While the audit function is an important component of monitoring access, it is not the principal function for monitoring access. The principal function for monitoring access is typically associated with access control mechanisms. Access control involves policies, procedures, and technical controls that determine who or what is allowed or denied access to a system or its resources.

    The audit function comes into play after access has occurred and involves reviewing logs and records to track and analyze system activities. It is a crucial part of monitoring and maintaining the security of a system, but it is not the primary function for controlling or managing access.

    Your users cannot access a server, and you notice almost 100% network saturation. Which of the following attacks might be underway?

    • A.

      Spam

    • B.

      DoS

    • C.

      Worm

    • D.

      Trojan horse

    Correct Answer
    B. DoS
    Explanation
    The correct answer is the DoS (Denial of Service) attack. A DoS attack occurs when an attacker overwhelms a server or network with a flood of illegitimate requests, causing it to become inaccessible to legitimate users. In this scenario, the high network saturation indicates that the server is being flooded with traffic, resulting in the denial of service to users. The other options, such as spam, worm, and Trojan horse, do not directly cause network saturation and prevent user access to the server.

      TACACS

    • B.

      RADIUS

    • C.

      Diameter

    • D.

      Circumference

    Correct Answer
    B. RADIUS
    Explanation
    In the context of providing secure remote access for roaming users, the most appropriate choice is B. RADIUS, as it is commonly used for authentication and authorization in remote access scenarios.

    A. TACACS (Terminal Access Controller Access Control System): TACACS is a security protocol that provides centralized validation of users attempting to gain access to a router or network access server. It's commonly used for device administration, not specifically for remote access or mobility.

    B. RADIUS (Remote Authentication Dial-In User Service): RADIUS is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service. It is often used for remote access solutions, including virtual private network (VPN) connections, making it suitable for providing secure remote access for roaming users.

    C. Diameter: Diameter is an authentication, authorization, and accounting protocol used for applications such as network access or IP mobility. While it is similar to RADIUS in its purpose, it is more extensible and designed to address some limitations of RADIUS.

    D. Circumference: There is no standard networking or security protocol known as "Circumference." It seems to be a term that does not relate to any common remote access mechanisms.

      Firewall

    • B.

      ACL

    • C.

      IPS

    • D.

      Intrusion protection system

    Correct Answer
    C. IPS
    Explanation
    An Intrusion Protection System (IPS) is a network security mechanism that monitors network traffic for suspicious activity or known attack patterns. It identifies intrusions and takes immediate action to block or prevent them. In the given scenario, the network has been attacked, and the question asks for the mechanism that should have identified and blocked the intrusion. A firewall and ACL (Access Control List) can provide some level of security, but they do not actively monitor and block intrusions like an IPS does. Therefore, the correct answer is IPS.

    Which data backup method is used to copy modified files to an offsite location?

    • A.

      Remote journaling

    • B.

      Electronic vaulting

    • C.

      Incremental backup

    • D.

      Differential backup

    Correct Answer
    B. Electronic vaulting
    Explanation
    Electronic vaulting is a data backup method that involves copying modified files to an offsite location. This method ensures that the most up-to-date versions of the files are stored in a secure location, protecting against data loss in case of a disaster or system failure. Unlike incremental or differential backups, electronic vaulting does not rely on keeping track of changes made to files over time, but rather focuses on regularly copying the modified files to a separate location for safekeeping.

    Which of these are single points of failure?

    • A.

      Disks

    • B.

      A local LAN

    • C.

      Servers

    • D.

      Circuits

    Correct Answer(s)
    A. Disks
    C. Servers
    D. Circuits
    Explanation
    Disks, servers, and circuits are all examples of single points of failure. A single point of failure refers to a component or system that, if it fails, will cause the entire system or network to fail. In the case of disks, if a disk fails, the data stored on it may be lost or inaccessible. Similarly, if a server fails, the services or applications it provides will be unavailable. Circuits, such as network connections or communication lines, if they fail, can disrupt the flow of data or communication within a network. Therefore, these components are considered single points of failure as their failure can have a significant impact on the overall system or network.

    As a starting point for all backup activities, what backup method should be used?

    • A.

      Electronic vaulting

    • B.

      Incremental backup

    • C.

      Differential backup

    • D.

      Full backup

    Correct Answer
    D. Full backup
    Explanation
    A full backup should be used as a starting point for all backup activities because it creates a complete copy of all data and files on a system. This ensures that in the event of data loss or system failure, all information can be easily restored. Incremental and differential backups only save changes made since the last backup, so they are not suitable as starting points for backup activities. Electronic vaulting, on the other hand, is a method of offsite storage for backups, rather than a backup method itself.
