Monitoring your firewall effectively is crucial to maintaining strong network security. Proper management of firewall rules and configurations can help prevent vulnerabilities and optimize network traffic, especially with firewall configuration, security policies, and automation.

Effective firewall monitoring begins with a thorough understanding of your firewall logs and network traffic. Regular audits can identify misconfigurations and vulnerabilities, ensuring that your firewall rules are up-to-date and your network remains secure.

Automating these processes can significantly enhance your ability to manage firewall configurations and respond to security threats promptly.

Network Changes in Days, Not Months

The cybersecurity team at a large U.S. utilities company evaluated options for best managing its firewall environment. Flexible automation, scalability, and breadth of integrations were top of mind.

They needed the ability to check the company's security policy against every rule exception request. Moreover, they wanted a solution that could implement and track changes in a single location for all the firewalls, routers, switches, and F5 and NSX devices in their environment. "Tufin checked all the boxes," commented the Senior Cybersecurity IT Solutions Engineer.

With Tufin network security solutions in place, the network security team has dramatically reduced the time and effort required to manage firewall rules and change requests. "The value becomes apparent," commented the Solutions Engineer, "when a workload that took 40 people, now takes about 5 people."

By implementing the Tufin Orchestration Suite, the team has been able to streamline their processes and reduce potential points of failure. The suite offers flexible automation and scalability, which is essential for maintaining efficient enterprise network security policy.

With this system, changes that once took months can now be executed in a matter of days, significantly boosting the team's ability to respond to security threats and vulnerabilities.

Automated, Streamlined Compliance Efforts

"We save countless hours on rule cleanup and compliance reporting, and we can give management visibility without pulling one of our valuable team members from critical tasks," explained the Cybersecurity Manager.

Tufin automatically identifies shadowed rules. Plus, it automatically reviews and tests every access change against the company's security policy. The company is also planning to leverage its ability to check against security intelligence from third-party solutions, such as the company's vulnerability management tool and its SIEM.

With immediate visibility into partial and fully shadowed rules, the team has reduced its time to identify and remediate these issues by 80%.

Ensure Uninterrupted Business with Path Analysis

With such a large deployment of firewalls in regulated and internal domains, being able to determine the cause for outages that may result from firewall policies or rules is essential for the network security team to provide rapid resolution.

During outages, Tufin's path analysis tool streamlined the process of identifying where the blockage is, reducing time to resolution by 50%. "The value becomes apparent when a workload that took 40 people now takes about 5 people," said the Senior Cybersecurity IT Solutions Engineer.

Tufin also offers solutions like network segmentation to further improve security and operational efficiency. By isolating network segments, the team can minimize the impact of any potential security breaches, ensuring that the rest of the network remains unaffected.

Future Plans: More Workflow Automation for Firewall Rule Changes

Going forward, the network security team plans to take greater advantage of Tufin's market-leading workflow automation, such as automatically permitting firewall rule changes that meet standard policies. "We want to continually reduce our SLAs," explained the Manager.

In addition, the team are also test-driving various Tufin extensions to better leverage intelligence from their vulnerability management platform and to get more advanced in automated rule lifecycle management.

The demands of DevOps processes and the rise of sophisticated cyberattacks have placed a premium on security talent. As a result, organizations are often forced to place increasing demands on security teams or settle for best-effort security in the name of cost and efficiency.

With policy-driven automation, organizations can meet the business need for agility and productivity while addressing the reality of a cybersecurity skills shortage. Automation solutions, for example, can be used to perform time-consuming calculations and analyses or handle mundane tasks that divert security resources from focusing on higher-level tasks and additional training.

With security policy automation, organizations can achieve higher levels of security with the resources they already have today.
