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

The attack described is known as DNS Poisoning, also referred to as DNS Spoofing. This type of attack occurs when an attacker manipulates the DNS server’s cache, so that the server returns an incorrect IP address for a website. This results in users being redirected to malicious websites instead of the intended destination. The attacker’s goal is typically to spread malware, steal personal information, or disrupt services. DNS Poisoning is a serious security threat because it can be used to compromise entire networks and is difficult to detect.

References: The concept of DNS Poisoning is a well-established security concern and is covered in various cybersecurity resources as a common method of attack12345.

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.

In the context of network security and event management, an ‘Error’ event type typically indicates a significant problem that could result in loss of data or loss of functionality. These events are logged when a system or application experiences a severe issue that prevents it from continuing normal operation. Unlike warnings or informational events, error events suggest a critical condition that may require immediate attention to prevent further damage or data loss.

References: The Certified Network Defender (CND) course by EC-Council includes detailed discussions on various event types and their significance in the realm of cybersecurity. The curriculum covers the importance of monitoring and managing error events as part of maintaining network security and ensuring the integrity and availability of data and services1.
