Here’s a breakdown of the usual review process:

Gathering Information: This phase involves gathering information about the organization's network architecture, including network diagrams, security policies, and configuration details.
Analyzing Network Design: This phase involves analyzing the network design to identify potential vulnerabilities and weaknesses. This includes analyzing network topology, protocols used, and segmentation.
Reviewing Security Controls: This phase involves reviewing the security controls in place, such as firewalls, intrusion detection systems, and access controls, to ensure they are properly configured and effective.
Assessing Policies and Procedures: This phase involves reviewing security policies and procedures to ensure they align with best practices and are being followed.
Reporting and Recommendations: This phase involves providing a detailed report of the findings, including recommendations for improving the network security architecture. This includes providing remediation guidance, prioritizing identified issues based on their severity, and providing recommendations for improving the overall security posture of the organization.

Step-by-step approach that we follow for a network security architecture review:

Pre-Assessment Planning: This phase involves defining the scope of the assessment, establishing clear goals and objectives, identifying the tools and techniques that will be used, and obtaining the necessary permissions and approvals to conduct the review.
Information Gathering: The next step involves gathering information about the organization's network infrastructure, including network diagrams, inventory lists, security policies and procedures, and any other relevant documentation.
Network Analysis: This phase involves analyzing the network architecture to identify potential vulnerabilities and weaknesses. This includes reviewing network topology, traffic flow, and segmentation, as well as identifying potential points of entry or areas of weakness.
Security Controls Review: This phase involves reviewing the security controls in place, such as firewalls, intrusion detection systems, and access controls, to ensure they are properly configured and effective.
Policy and Procedure Assessment: This phase involves assessing security policies and procedures to ensure they align with best practices and are being followed.
Testing and Validation: In some cases, it may be necessary to conduct vulnerability testing or penetration testing to identify potential vulnerabilities and weaknesses that may not be apparent through other analysis techniques.
Reporting and Recommendations: After completing the review, a detailed report is provided that outlines the findings, including any potential vulnerabilities and weaknesses that were identified, as well as recommendations for improving the network security architecture. This includes providing remediation guidance, prioritizing identified issues based on their severity, and providing recommendations for improving the overall security posture of the organization.

Benefits of Performing Network Security Architecture Review:

Identify security vulnerabilities: A thorough review can help identify potential security gaps, vulnerabilities, and misconfigurations in network architecture. This can help to prevent security breaches and protect sensitive data.
Ensure compliance: Network security architecture review can ensure that the organization's network architecture is in compliance with regulatory standards and industry best practices. This can help the organization to avoid costly penalties and damage to reputation.
Improve security posture: By identifying potential security threats and vulnerabilities, organizations can take proactive measures to improve their security posture. This includes implementing better security controls and policies, and making necessary changes to their network architecture.
Reduce risk: A comprehensive network security architecture review can help organizations identify and reduce risk associated with their network infrastructure. This can help organizations to avoid potential security incidents and financial losses.
Increase awareness: Network security architecture review can help raise awareness of security issues among staff members, helping them to be more vigilant and proactive in identifying potential security threats.
Improve incident response: By reviewing the organization's network security architecture, organizations can better understand how to respond to security incidents and quickly contain them to prevent further damage.
