Firewalls are devices used for segmentation of networks and it is a basic cyber security product that every entity has in their infrastructure. For this post we have asked ChatGPT what additional tasks that must be done on a firewall apart from rule creation. See how it has responded to this question.

Here are some common tasks that are typically performed on a firewall:
- Configuration and management: Setting up the firewall, configuring network settings, and managing the firewall through a graphical user interface or command line interface.
- Monitoring and logging: Keeping track of network traffic, identifying security threats, and generating logs to help diagnose issues and track activity.
- Updating software and firmware: Ensuring that the firewall has the latest security updates, bug fixes, and new features.
- Performance tuning: Adjusting settings to optimize firewall performance and minimize latency.
- Network segmentation: Segmenting the network into different zones to limit the spread of security threats and enhance network security.
- VPN support: Configuring and managing Virtual Private Network (VPN) connections for secure remote access to the network.
- Authentication: Implementing authentication mechanisms, such as user and device authentication, to ensure that only authorized users can access the network.
- Disaster recovery: Having a plan in place to recover from a firewall failure or security breach.
- Compliance: Ensuring that the firewall configuration and usage meet regulatory requirements and industry standards
- Intrusion detection and prevention: Monitoring network traffic for signs of malicious activity and taking action to prevent security breaches.
- Traffic shaping: Managing network traffic to ensure optimal use of network resources and prevent network congestion.
- URL filtering: Blocking access to specified websites or categories of websites, such as those containing malicious or inappropriate content.
- Application control: Controlling access to specific applications and protocols based on business needs and security policies.
- Content filtering: Screening incoming traffic for inappropriate or malicious content, such as viruses, malware, or phishing attempts.
- Data protection: Encrypting sensitive data transmitted over the network to protect it from theft or unauthorized access.
- High availability: Implementing failover mechanisms to ensure that the firewall remains operational in the event of a failure or outage.
- Reporting and analysis: Generating reports and analyzing logs to identify trends and potential security threats, and to track firewall performance.
- Training and documentation: Providing training and documentation for firewall administrators and users to ensure proper usage and maintenance of the firewall

So, it is clear that there are several important tasks to be done on firewalls. If you have a chance to automate policy change activity or any similar activity that is repeatitive that certainly makes sense. Otherwise, you need to have a larger team that would handle that much activity.
