Firewall Configuration Reviews are a crucial component of cybersecurity penetration testing, focusing on the evaluation and analysis of firewall settings and policies to ensure they adequately protect the network infrastructure from unauthorized access and potential threats. Firewalls act as the first line of defense in a security architecture, controlling incoming and outgoing network traffic based on predetermined security rules. Therefore, a well-configured firewall is essential for safeguarding sensitive data and maintaining the integrity of an organization’s IT environment

Purpose of Firewall Configuration Reviews:
The primary objective of firewall configuration reviews is to identify
misconfigurations, vulnerabilities, or gaps in the firewall’s security posture that could be exploited by malicious actors. By thoroughly assessing the firewall settings, organizations can enhance their security measures and ensure compliance with industry best practices and regulatory requirements.
