Automating Network Changes with Tufin: Enhancing Security and Efficiency

In today’s dynamic world, where network infrastructure is becoming increasingly complex and distributed, manual change management is becoming a source of serious problems. Configuration errors, deployment delays, non-compliance with security requirements – these are just some of the challenges faced by IT professionals. Manually managing network change processes takes a huge amount of time, increases the risk of configuration errors, and negatively affects the overall security of the IT infrastructure, making it difficult to respond promptly to changing business needs and new threats.

Automating network changes is a necessity, not a luxury. Tufin offers a platform that allows organizations to simplify, automate, and orchestrate network security policy management processes throughout the entire change lifecycle, from planning to implementation and rollback. Instead of simply listing Tufin’s capabilities, we will look at the problems it solves and how it does it, providing specific examples and technical details.

Benefits of Network Change Automation

Implementing an automation solution, such as Tufin SecureChange, does not simply optimize individual tasks, but fundamentally changes the approach to network infrastructure management. Here are the key benefits, supported by examples:

• Reduced Change Implementation Time: Faster Time to Market by automating workflow and approval processes.Example: Instead of several days for manual configuration, changes are implemented in minutes thanks to automated workflows and integration with network device APIs.
• Reduced Risk of Errors: Minimizing human error and related errors through automated checks and validation.Example: Automatic rule correctness checks and compliance validation eliminate configuration errors that often occur with manual management.
• Enhanced Security: Improved compliance through process standardization and automatic application of network security policies.Example: Standardization of processes allows you to quickly identify and eliminate deviations from security policies, such as unauthorized port openings.
• Improved Compliance: Compliance with regulatory requirements, thanks to built-in audit reports and automated compliance checks.Example: Automatically generating PCI DSS compliance reports, including a breakdown of the requirements that have been checked automatically, greatly simplifies the audit process.
• Resource Optimization: Reducing manual labor costs and improving the efficiency of DevOps and security teams.Example: Automation can reduce the time to process change requests by 50%, freeing up resources for other tasks.

• SecureChange: Responsible for automating change workflows, analyzing risks, and implementing changes.
• Connectors: Provide integration with various firewalls, routers, and other network devices.Connector Types: API, SSH, CLI. Connectors provide support for various devices, including vendor-specific commands.
• API: Provides the ability to integrate with other systems and tools, such as CI/CD pipelines and monitoring systems.Examples of API Usage: Automating change requests, retrieving network status information (REST, SOAP).

Tufin Integration with Cloud Platforms for Automation

Modern organizations are increasingly using cloud platforms such as AWS, Azure, and GCP to deploy their applications and services. Tufin provides integration with these platforms, allowing organizations to centrally manage network security policies in both on-premises infrastructure and in the cloud.

Benefits of Integration with Cloud Platforms

• Unified Management: A single interface for managing network security policies in hybrid environments.How Tufin Provides Unified Management: Tufin provides unified management using the AWS Security Groups, Azure Network Security Groups, and GCP Firewall Rules APIs. This allows administrators to centrally manage security policies, regardless of where the resources are located.
• Automated Policy Enforcement: Automatically apply network security policies when creating new resources in the cloud.Example: Tufin automatically applies security policies when creating new EC2 instances in AWS, ensuring compliance from the start.
• Enhanced Security: Improved visibility and control over network security policies in cloud infrastructure.How Visibility is Improved: Tufin tools are used to monitor and analyze traffic in the cloud, identify anomalies and unauthorized changes.
• Simplified Compliance: Automate compliance processes in the cloud environment.

Tufin SecureApp: Automating Security Changes at the Application Level

In addition to automating network changes at the network level, Tufin also offers Tufin SecureApp, a solution for automating security changes at the application level. Tufin SecureApp allows organizations to automate security processes for new and existing applications, integrating network security information with the application development lifecycle.
