Firewall Maintenance Package - More Info
Firewall Maintenance Plan Overview
Your industrial firewalls play a crucial role in the defense-in-depth model for Industrial Control Systems (ICS), preventing unauthorized access to Operational Technology (OT) systems and reducing operational disruptions. Over time as the site evolves, the firewall integrity tends to drift due to a carousel of administrators / integrators configuring the appliance, lack of a maintenance plan, resource time constraints, and an evolution of the site’s communication profile, leading to a false sense of security. Our annual Firewall Maintenance Plan aims to help you sleep better at night knowing that your firewall is properly configured and optimized for your environment. This proactive approach minimizes risks, enhances security, and keeps your firewall up to date, ensuring continuous protection and optimal performance throughout the year.
Key Features:
- Rule / Policy rationalization: Optimize firewall performance by rationalizing rules and policies.
- Identify duplicate, overlapping, and unused objects & object groups: Streamline configurations by identifying and removing redundant objects and groups.
- Research firmware / OS for vulnerabilities and vendor recommendations: Ensure your firewall is secure by researching and addressing firmware and OS vulnerabilities.
- Compile MoC request: Document necessary adjustments through Management of Change requests.
- Make recommendations for devices requiring hardware upgrades: Provide expert advice on hardware upgrades needed for optimal performance and security.
- Remote firewall maintenance: Remotely perform rule updates, object/group cleanup, and patching to keep your firewall up-to-date.
- Provide a high-level summary report: Keep you informed of all actions taken and their impact on your network security.
NIST CSF 2.0 Controls Addressed: ID.AM-08, ID.RA-01, PR.PS-02, PR.PS-05
Benefits
- Proactive Risk Management: By addressing configuration drift, outdated firmware, and unused rules or objects, the plan helps prevent vulnerabilities before they can be exploited.
- Strengthened OT Security Posture: Regular maintenance ensures your industrial firewalls remain a strong line of defense, reducing the risk of unauthorized access and operational disruptions.
- Optimized Firewall Performance: Rule and policy rationalization, along with cleanup of redundant objects, streamlines firewall operations, improving efficiency and reducing latency.
