The Firewall Lockdown teams core function is to ensure firewall rule compliance with current VISA policies, specifically Key Controls and Technical Security Requirements. We validate firewall rules to address high-risk network communications for Visa applications and processes, ensuring the firewall rules in our network environment remains non-risky / compliant with evolving network and zoning requirements. A primary focus is the remediate & cleaning up and hardening of the existing firewall rules through the removal of expired rules. The team proactively identifies rules violating Visa Technical Security Requirements and inconsistent with Visas least privilege access model. We conduct thorough traffic reviews for each violating rule and engage affected ATCs via multiple email communications. ATCs are then expected to either extend the rules expiration, reject it, or disable it. The firewall lockdown project has successfully transitioned into a BAU process, continuously addressing non-compliant rules. By comparing firewall rules against TSR, we actively manage legacy communications that may no longer meet current policy standards, ultimately fortifying Visas network security posture. Essential Functions: Drive core responsibilities including, but not limited to, in-depth rule auditing, zero-hit rule cleanup, management of expiring rules, identification and mitigation of high-risk rules, resolution of non-compliant rules, and the precise remediation and modification of firewall rules, strictly adhering to established change management protocols. Execute systematic and ad-hoc reviews of firewall rulesets, with a primary focus on Checkpoint and Palo Alto platforms, to ensure stringent adherence to established security policies, industry best practices, and regulatory compliance mandates. Lead comprehensive firewall rule audits, proactively identifying and addressing redundant, obsolete, or overly permissive rules, and formulating actionable remediation strategies. Develop and meticulously maintain comprehensive documentation for all firewall rules, encompassing their stated purpose, designated owner, and defined expiration dates. This includes fostering effective communication and collaboration with application owners to ensure alignment and accuracy. Collaborate strategically with internal security and assurance teams to thoroughly comprehend compliance requirements, translating these into secure, optimized, and efficient firewall rule configurations. Monitor and analyze firewall logs and security alerts to detect suspicious activities, policy violations, and potential security incidents, leveraging a strong understanding of security monitoring principles. Provide expert guidance and support on firewall security best practices, robust vulnerability management strategies, and effective threat mitigation techniques. Possession of demonstrable experience in troubleshooting network connectivity issues directly related to firewall rules, including those involving load balancers and other critical network infrastructure components, is a distinct advantage.
