CISSP Certification: Domains 1, 2, 3 & 4 Video Training-2021

1. Domain 4 - Communication and Network Security: This domain covers the principles and practices related to securing network architectures, components, and communication channels. It encompasses a broad range of knowledge, including:

   • Secure Design Principles in Network Architectures: Understanding the Open System Interconnection (OSI) model, TCP/IP stack, implications of multilayer protocols, converged protocols, software-defined networks, and wireless networks is crucial. Knowledge of how these models and technologies apply to secure network design and the importance of each layer in providing security features.

   • Secure Network Components: Familiarity with how hardware, transmission media, Network Access Control (NAC) devices, endpoint security, and content-distribution networks function within a secure network environment. You should understand the operational aspects and challenges associated with these components.

   • Implement Secure Communication Channels: This includes voice, multimedia collaboration, remote access solutions, data communications, and virtualized networks. Understanding encryption, authentication protocols, secure communication channels, and their implementation is essential.

2. Notes / Disclaimers:

   • Experience and Knowledge: The CISSP test requires substantial knowledge through experience and education. It's not just theoretical but also practical understanding of the concepts.

   • Language Versions: Although the original test is in English, there are language options available for non-English speakers.

   • Test Perspective: Answers should be given from a managerial or executive point of view (such as CISO or Risk Adviser), rather than purely technical. This reflects the strategic and policy-making nature of the CISSP certification.

   • Keywords and Indicators: Identifying keywords like "DR," "BCP," "Policy," "Standards," etc., and understanding indicators (first, best, last, least, most) will help in answering the questions accurately.

   • Proactive Approach: The CISSP certification emphasizes a proactive stance on security management. It's about enabling programs before issues arise.

   • Test Format and Duration: The CISSP exam is a 3-hour test, using the Computerized Adaptive Testing (CAT) format, with 100-150 questions in the English version.

   • Study Resources: It's advisable to use multiple training materials and resources to prepare for the CISSP exam, as this will provide a comprehensive understanding of the material covered by the certification.

To pass the CISSP exam, you must integrate your knowledge from your experience and education with the study materials provided by various sources. The exam tests your ability to apply security concepts in a managerial context, ensuring that you can make strategic decisions that protect an organization's information assets effectively. Remember, the goal of the CISSP certification is to affirm that you have a deep understanding of the principles and practices in all areas of an overall security program.
