      Tom is a network technician of his company. Now, he is making a decision between implementing a HIDS on the database server and implementing a NIDS. Why would a NIDS be better to implement (Select TWO).

    • Many HIDS are not good at detecting attacks on database servers

    • Many HIDS only offer a low level of detection granularity

    • Many HIDS have a negative impact on system performance

    • Many HIDS are not able to detect network attacks

    Correct Answer(s)
    A. Many HIDS have a negative impact on system performance
    A. Many HIDS are not able to detect network attacks
    Explanation
    A Network Intrusion Detection System (NIDS) would be better to implement because many Host Intrusion Detection Systems (HIDS) are not able to detect network attacks, which are a common type of attack on database servers. Additionally, many HIDS have a negative impact on system performance, which can affect the overall functioning of the database server. Therefore, implementing a NIDS would provide better protection against network attacks and minimize the impact on system performance.

      Which of the following types of removable media is write-once and appropriate for archiving security logs?

    • CD-R

    • USB drive

    • Tape

    • Hard disk

    Correct Answer
    A. CD-R
    Explanation
    CD-R (Compact Disc-Recordable) is a type of removable media that can only be written to once. It is a suitable option for archiving security logs because once the logs are written onto the CD-R, they cannot be altered or modified, ensuring the integrity and security of the data. CD-Rs are also relatively inexpensive and have a long lifespan, making them a reliable choice for long-term storage and archiving purposes.

      An outside auditor has been contracted to determine whether weak passwords are being used on the network. In order to achieve this goal, the auditor is running a password cracker against the master password file. Which of the following is this an example of?

    • Vulnerability assessment

    • Fingerprinting

    • Malware scan

    • Baselining

    Correct Answer
    A. Vulnerability assessment
    Explanation
    This scenario is an example of a vulnerability assessment because the outside auditor is specifically checking for weak passwords on the network. A vulnerability assessment is the process of identifying and evaluating potential vulnerabilities in a system or network to determine the level of risk. In this case, the auditor is using a password cracker to test the strength of the passwords in the master password file, which is a common method used in vulnerability assessments to identify potential weaknesses in password security.

      In computer security, an access control list (ACL) is a list of permissions attached to an object. Which log will reveal activities about ACL?

    • Performance

    • Firewall

    • Mobile device

    • Transaction

    Correct Answer
    A. Firewall
    Explanation
    A firewall is a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It is designed to prevent unauthorized access to or from a private network. As access control lists (ACLs) are a fundamental component of network security, a firewall log will reveal activities related to ACLs. This log will provide information about any attempts to access or modify permissions associated with objects, helping to identify potential security breaches or unauthorized actions.

      For the following items, which one is a collection of servers setup to attract hackers?

    • VLAN

    • Honeynet

    • DMZ

    • Honeypot

    Correct Answer
    A. Honeynet
    Explanation
    A honeynet is a collection of servers that are intentionally set up to attract hackers. It is designed to gather information about their tactics, techniques, and motives. By luring hackers into the honeynet, organizations can study their behavior, identify vulnerabilities, and develop strategies to enhance their cybersecurity defenses. Unlike a honeypot, which is a single decoy system, a honeynet consists of multiple interconnected systems that mimic a real network environment. This allows for a more comprehensive analysis of hacker activities and provides valuable insights for improving overall network security.

      A network intrusion detection system (NIDS) is an intrusion detection system that tries to detect malicious activity such as denial of service attacks, port scans or even attempts to crack into computers by monitoring network traffic. Which NIDS configuration is solely based on specific network traffic?

    • Host-based

    • Signature-based

    • Anomaly-based

    • Behavior-based

    Correct Answer
    A. Signature-based
    Explanation
    Signature-based NIDS configuration is solely based on specific network traffic. This configuration uses predefined patterns or signatures to identify known threats and malicious activity. It compares the network traffic against a database of signatures and if a match is found, it raises an alert. This approach is effective in detecting and preventing known attacks, but it may not be able to detect new or unknown threats.
