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

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 strategy described is known as a “default deny” firewall policy. This approach means that the firewall is configured to deny all traffic by default, except for the network services that are explicitly allowed. It is a restrictive security stance where only specified services are permitted, and everything else is blocked. This is considered a best practice in firewall configuration because it minimizes the attack surface by ensuring that only necessary services are accessible, thereby reducing the potential vectors for attack.

References: The concept of a default deny policy is a fundamental principle in network security and is advocated by various cybersecurity authorities, including the EC-Council’s Certified Network Defender (CND) program. It is also detailed in cybersecurity literature and aligns with best practices from organizations such as the National Institute of Standards and Technology (NIST)123.

To check if SMB1 is enabled or disabled, the correct PowerShell command is Get-WindowsOptionalFeature -Online -FeatureName SMB1Protocol. This command queries the status of the SMB1Protocol feature in the running instance of Windows. If SMB1 is enabled, the command will return its status as ‘Enabled’, and if it is disabled, it will return ‘Disabled’.

References: The correct syntax for the command is documented in various official Windows resources, including Microsoft’s own documentation on managing SMB protocols1. It is also aligned with the objectives of the EC-Council’s Certified Network Defender (CND) program, which includes knowledge of managing Windows network protocols and features.
