Firewall Support & Maintenance

Configuring firewall rules and policies to filter network traffic based on criteria such as IP addresses, port numbers, protocols, and application signatures. This involves defining access controls to allow or deny traffic flows between different network segments and to and from the internet.

Managing firewall rule sets to ensure they are up-to-date, relevant, and aligned with security requirements and best practices. This includes reviewing, modifying, and optimizing firewall rules as needed to maintain an effective security posture while minimizing the risk of false positives and negatives.

Implementing intrusion detection and prevention system (IDPS) capabilities within firewalls to identify and block malicious or unauthorized network activity in real-time. This may involve configuring intrusion detection signatures, threat intelligence feeds, and anomaly detection mechanisms to detect and mitigate security threats.

Monitoring network traffic passing through the firewall for suspicious or anomalous patterns, security events, and policy violations. Analyzing firewall logs and traffic data to identify potential security incidents, performance issues, and areas for improvement.

Performing routine administrative tasks such as firewall software updates, patches, and firmware upgrades to ensure the firewall is running the latest security patches and features. This also includes managing firewall licenses, certificates, and other configuration settings.

Enforcing security policies and compliance requirements through the firewall, such as regulatory standards (e.g., PCI DSS, GDPR), industry best practices, and organizational security policies. This may involve implementing content filtering, application control, and URL filtering to enforce acceptable use policies and prevent access to malicious or inappropriate content.

Responding to security incidents and conducting forensic analysis of firewall logs and traffic data to investigate security breaches, unauthorized access attempts, and other security events. This includes documenting incident details, identifying root causes, and implementing remediation measures to prevent recurrence.

Providing training and awareness programs for network administrators, IT staff, and end-users to educate them about firewall security principles, best practices, and common threats. Empowering users to recognize and report suspicious activity and adhere to security policies helps strengthen the overall security posture of the organization.
