Job Description

You will be responsible for reviewing and approving firewall requests in line with the risk appetite of the organization. Your role will involve reviewing and analyzing firewall rules to ensure their effectiveness and alignment with security best practices. It will be crucial for you to ensure that all firewall rules are recertified by owners within the specified timeframe. In cases where no owner is assigned, you will be required to find an owner and update the necessary information accordingly. Your duties will include performing firewall ruleset reviews and validating rule compliance reports generated from automated firewall review solutions. You will need to collaborate with stakeholders and manage ACL ruleset by adding, updating, removing, and optimizing rules to eliminate defunct or duplicate entries. Adherence to the change management process for creating, modifying, or removing rules with appropriate approvals is essential. Documenting all changes to firewall rules comprehensively is a key aspect of this role. This documentation should include the reason for the change, details of the change, the requestor's information, and the date and time of the change. Regularly reviewing existing firewall rules to ensure their necessity and appropriateness is also part of your responsibilities. Outdated or redundant rules should be identified and removed, while adjustments to rules based on identified issues should be made as necessary. In terms of experience qualifications, you should possess 16 to 20 years of experience in setting up, configuring, and managing firewall devices such as Palo Alto, F5, Zscaler, Cisco ISE, Azure, and DDoS solutions. A strong background in Network Architecture and the ability to design and develop the architecture framework are essential. Experience in preparing High-Level Design (HLD) and Low-Level Design (LLD) documents, managing end-to-end delivery, and excellent communication skills are required. Moreover, you should demonstrate strong leadership and team management skills, along with the ability to collaborate effectively with cross-functional teams. Possessing certifications such as CISSP, Certified Ethical Hacker (CEH), or CISM would be considered advantageous for this role.,
