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

Stephanie is working on ensuring data integrity for her company’s email communications. Data integrity refers to the assurance that data has not been altered or tampered with during transit. By setting up encryption, Stephanie is ensuring confidentiality, which protects the contents of the email from being read by unauthorized parties. However, to ensure that the emails have not been modified, she is implementing digital signatures. Digital signatures provide a means to verify the authenticity of the sender and to ensure that the message has not been changed, which directly relates to the concept of data integrity in cybersecurity.

References: The information aligns with the objectives and documents of the EC-Council’s Certified Network Defender (CND) program, which emphasizes the importance of protecting data integrity through measures like digital signatures as part of a defense-in-depth security strategy1.

Indicators of Compromise (IoCs) are clues, artifacts, or evidence that suggest a potential intrusion or malicious activity within an organization's infrastructure. IoCs are used to identify and respond to security breaches and can include log entries, file hashes, unusual network traffic, or specific patterns that match known threats.

• Indicators of Attack (IoA): Focus on detecting the methods and techniques used by attackers.
• Key Risk Indicators: Metrics that indicate increased risk levels.
• Indicators of Exposure: Signs that reveal vulnerabilities or weaknesses in the system.

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.
