312-38 Exam Dumps : Certified Network Defender (CND)

After completing the vulnerability scanning process and identifying serious vulnerabilities, Harry will proceed through several phases of vulnerability management to address and eradicate these vulnerabilities. The phases include:

• Mitigation: This phase involves taking steps to reduce the impact of the detected vulnerabilities. Mitigation strategies may include applying patches, adjusting configurations, or implementing compensating controls to lower the risk associated with the vulnerabilities.
• Verification: In this phase, Harry will verify that the vulnerabilities have been successfully mitigated or remediated. This typically involves re-scanning the network to ensure that the vulnerabilities are no longer present or that their risk has been sufficiently reduced.
• Remediation: This is the phase where Harry will take action to fix the vulnerabilities. Remediation can involve patching software, closing unnecessary ports, changing passwords, or other actions that directly address the identified security issues.

These phases are part of a broader vulnerability management lifecycle, which also includes assessing vulnerabilities and reassessing the network after remediation efforts to ensure continuous protection.

References: The explanation provided is based on the standard vulnerability management lifecycle, which includes assessment, prioritization, action (mitigation and remediation), reassessment, and improvement as outlined in cybersecurity resources123.

The Zero-trust network model is designed to ensure strict identity verification for every user or device attempting to access network resources, regardless of whether they are inside or outside the network perimeter. This model operates on the principle of “never trust, always verify,” which means that no one is trusted by default, and verification is required from everyone trying to gain access to resources on the network. On the other hand, the Castle-and-Moat model operates on the principle that once inside the network, users or devices are generally trusted. This model does not enforce strict identity verification for every user or device within the network, which is a fundamental difference from the Zero-trust model.

References: The information about the Zero-trust network model aligns with the Certified Network Defender (CND) course objectives, which include understanding various network security models and their characteristics. The Zero-trust model’s emphasis on strict identity verification is a key aspect of modern network security practices12. The Castle-and-Moat model’s approach of trusting users once they are inside the network is contrasted with the Zero-trust model in various security literature34.

To ensure the integrity of the message and prevent it from being altered in transit, hashing can be used. Hashing is a process where a hash function converts data into a fixed-size string of characters, which is typically a hash code. When the message is sent, the hash code is generated and sent along with it. Upon receipt, the receiver can run the same hash function on the received message to generate a new hash code. If this new hash code matches the one sent with the message, it confirms that the message has not been altered. This method does not encrypt the message content but ensures that any changes to the message in transit can be detected.

References: The explanation is based on the principles of message integrity and non-repudiation as outlined in the EC-Council’s Certified Network Defender (CND) program, which includes understanding of network security controls and protocols, as well as the application of security measures to protect data integrity12.
