New Release 312-38 CND Questions

 In the context of incident response methodology, the last step is typically referred to as ‘Post-Incident Activity’ or ‘Lessons Learned’. This step involves reviewing the incident to understand what happened, how it was handled, and how similar incidents can be prevented or mitigated in the future. It’s a critical phase where the organization can improve its security posture and response strategies. The follow-up step ensures that any residual risk is addressed, and that all documentation is completed. It also provides an opportunity for the incident response team to reflect on their actions and improve the incident handling plan for future responses.

References: The importance of the follow-up step as the last phase in the incident response methodology is supported by well-respected frameworks developed by NIST and SANS, which outline ‘Post-Incident Activity’ or ‘Lessons Learned’ as the final step123. These steps align with the objectives and documents of the EC-Council’s Certified Network Defender (CND) program.

In the context of digital certificates, the Registration Authority (RA) is responsible for verifying the identity of entities requesting a certificate before the Certificate Authority (CA) issues it. The RA acts as a verifier for the CA, ensuring that the entity requesting the certificate is who they claim to be. This process is crucial for maintaining trust within a digital environment, as it prevents the issuance of certificates to fraudulent or unauthorized entities.

References: The role of the Registration Authority in the verification process is outlined in the EC-Council’s Certified Network Defender (CND) curriculum, which covers the essential concepts of network security, including the management and issuance of digital certificates.

The tool that can help in identifying Indicators of Exposure (IoEs) to evaluate the human attack surface is the Social-Engineer Toolkit (SET). SET is designed for social engineering penetration tests and is effective in simulating phishing attacks, which are a common method to evaluate the human aspect of security. It helps in identifying the potential human vulnerabilities that could be exploited in an organization.

References: The EC-Council’s Certified Network Defender (CND) program includes discussions on various tools and methods for assessing and improving the security of an organization, including the human attack surface and the use of tools like SET for this purpose12.

Multilayer inspection firewalls, also known as Next-Generation Firewalls (NGFWs), are designed to provide comprehensive security by inspecting traffic across multiple layers of the TCP/IP model. These firewalls offer protection at the:

• Application Layer: They can analyze and filter traffic based on application-level protocols and payloads, such as HTTP, FTP, and DNS, providing protection against application-specific attacks.
• Transport Layer (TCP): They inspect the transport layer to monitor and control TCP/UDP traffic, preventing threats such as port scans and DoS attacks.
• Internet Layer (IP): They filter and monitor IP packets, enforcing security policies based on IP addresses and ensuring protection against IP-level attacks like IP spoofing.

By operating at these layers, multilayer inspection firewalls provide a robust defense mechanism against a wide range of network threats.
