Firewall Audit Tools to Ease PCI Compliance

If you are already working on hundreds of rules across multiple firewalls, you may need firewall audit software. Firewall audit tools automate analyzing complex and bloated rule sets to validate and demonstrate enterprise access controls and configuration change management processes.

Firewall compliance tools help meet PCI DSS requirements and take on tasks to help organizations improve network performance, reduce downtime, improve security, and support personnel eliminate firewall issues and analyze configurations.

Firewall management issues are experienced by organizations of all sizes, from inefficient firewalls to large, distributed organizations with many or hundreds of firewalls managed by many business units.

Not long ago, the use of 200 rules in firewalls was considered excessive. However, it is not uncommon for firewalls to have hundreds or even thousands of rules, many of which are overridden when IT operations add new rules and neglect to remove old ones to meet business demands. Analyzing the configurations of a few firewalls, much alone hundreds, has outpaced human computational capabilities.

What are the Key Benefits and Usage Examples of Firewall Audit Tools?

Firewall Audit Tools may be used to meet business efficiency, security, or PCI compliance requirements. You should review firewall and router configurations every six months to ensure PCI DSS compliance. Firewall audits are also often subject to scrutiny during internal, public, and other regulatory audits.

Organizations spend countless man-hours analyzing firewall and router configurations to produce audit reports but realize they don’t have a solid grasp of network access controls and the change management processes that enable them.

For example, manually proving that a firewall ruleset with 1000 rules is robust and secure is difficult and time-consuming.

Firewall rule analyzer tools use sophisticated algorithms that evaluate actual rules against corporate policies and best practices to identify gaps, verify changes, and generate audit reports.

Firewall audit tools enable organizations to validate and document the entire configuration management lifecycle to demonstrate to auditors that they follow policy and that changes have been authoritatively completed and granted the intended access.

While compliance automation is sufficient justification for their implementation, firewall auditing tools also offer tangible business benefits beyond the audit ordeal.

Performance and Optimization: In fact, performance and optimization are the main functions of all automated tools. Firewall performance suffers because excessive rules consume CPU cycles, and critical access rules are placed far down the hierarchy. Because when adding rules to the firewall, the focus is often on implementation speed rather than optimizing configuration. Firewall auditing tools remove redundant firewall rules and service requests that have previously been enabled, as well as rules that apply to objects that are no longer in use or don’t exist at all.

Optimizing firewalls and network devices can improve companies’ hardware refresh requirements and performance issues. Firewall optimization benefits will become even more apparent as traffic increases.

Security: Complex configurations in firewalls make security analysis very difficult. Outdated or misconfigured rules can be exploited to allow attackers to access sensitive data. Firewall administrators under pressure to fulfill business requests are likely to make the mistake of giving too much access instead of too little. Firewall configuration audit tools increase security by identifying optimal rules and detecting unused and misconfigured rules.

Business Continuity: Performance and optimization issues can seriously slow down or even disrupt critical business processes. Interruption or slowdown of business continuity costs the business loss of revenue and man-hours it must spend dealing with problems.

Change Management: Change management policies and processes may be inadequate when the policies do not make changes. Failure to follow procedures for changes usually occurs when there is an urgent need to enable or restore service for critical business processes. Some vendors have complementary workflow products that automatically document all configuration changes and reconcile them with their ticketing system.

Firewall Upgrade and Migration: Upgrading and consolidating firewalls across fewer platforms creates excellent opportunities for organizations to use an audit tool. Firewall audit tools can be used to make configuration cleanup and firewall optimization cost-effective, rather than migrating old infrastructure issues to the new environment. Firewall configuration audit tools are well suited for consolidation because they support multiple firewall platforms. It streamlines each platform configuration and transfers them to the new platform.

Firewall Policy Audit Tools

The hundreds or even thousands of rules that run on a firewall device determine how effective it is. Firewalls might fail to perform their vital functions due to misconfigurations, underused rules, and conflicting rules. Firewall security management products can help security administrators monitor compliance, edit device policies, optimize rules, and manage firewall changes.

When choosing firewall security management software, the most important criteria to consider are visibility, scalability, and guaranteed security and compliance for network devices.

One of the most challenging components of corporate network security is firewall management. The main problem is that many enterprise networks are complex, containing a mix of many different vendors and technologies, making it time-consuming and challenging to maintain and support.

Major firewall vendors such as Cisco, Checkpoint, Fortinet, or Palo Alto offer their firewall management software for centralized control of configurations, updates, and policy management.

This is because it is incredibly time-consuming and inefficient to go through each of your firewall devices individually to configure and manage them.

However, there are also networks with a mix of different firewall vendors, making it difficult to manage from a single central console. This is precisely where custom firewall management and editing tools come into play.

If you’re struggling with firewall management, you can find our list of firewall management solutions and firewall audit tools below.
