ECCouncil 312-38 Questions Answers

The log entry %ASA-6-11008 indicates that the message is of a severity level 6, which corresponds to an informational message. In the context of Cisco ASA Firewall logs, severity levels range from 0 (emergency) to 7 (debugging), with lower numbers indicating higher severity. A severity level of 6 is used for messages that provide information about normal but significant events. In this case, the log indicates that a user named ‘enable_16’ executed the ‘configure term’ command, which is a noteworthy event but does not indicate an error or critical condition.

References: This interpretation is based on the Cisco Secure Firewall ASA Series Syslog Messages documentation, which outlines the different severity levels and their meanings1.

The measures Damian is implementing are part of the Physical layer of network defense-in-depth strategy. This layer involves securing the physical infrastructure of the organization, which includes controlling physical access to the building through mechanisms like two-factor authenticated locks and monitoring the environment with video surveillance. Additionally, implementing fire suppression systems is a part of safeguarding the physical premises against environmental hazards. These measures are essential to prevent unauthorized physical access and to protect against physical threats that could harm the network’s infrastructure. References: The Certified Network Defender (CND) program by EC-Council covers a defense-in-depth security strategy that includes the Physical layer as one of its core components12.

 RAID level 0, also known as striping, provides very good data performance because it spreads data across multiple disks, which can significantly increase speed for read and write operations. However, it does not offer fault tolerance or data redundancy. If any single disk fails in a RAID 0 setup, all data in the array is lost, making it unsuitable for mission-critical systems.

References: The EC-Council’s Certified Network Defender (CND) course materials discuss RAID levels and their characteristics. RAID level 0 is specifically mentioned for its high performance but lack of fault tolerance and redundancy123.

Implementing access control mechanisms like a firewall is a preventive measure in network defense. The preventive approach focuses on establishing barriers and safeguards to stop security incidents before they occur. Firewalls are a core component of this strategy, as they control incoming and outgoing network traffic based on predetermined security rules, thereby preventing unauthorized access to or from a network.

References: The Certified Network Defender (CND) program emphasizes a multi-layered defense strategy, which includes the Protect, Detect, Respond, and Predict framework. Within this framework, the Protect phase aligns with the preventive approach, as it involves the implementation of security measures that aim to prevent threats from compromising the network1. This is further supported by the NIST Cybersecurity Framework, which outlines Identify, Protect, Detect, Respond, and Recover as the five core functions for a comprehensive cybersecurity approach2.
