How Tufin Ensures Hybrid Cloud Security: A Technical Overview

Tufin Orchestration Suite consists of several key components that together provide comprehensive hybrid cloud protection:

Tufin SecureTrack: Visibility and Analysis

Tufin SecureTrack provides full network visibility across the entire hybrid cloud infrastructure. It collects data from various sources, including firewalls, cloud platforms (AWS, Azure, GCP). Integration with intrusion detection systems (IDS) is usually done through SIEM, not directly. Tufin SecureTrack is primarily focused on the configuration of network devices and cloud services. Tufin SecureTrack also performs risk analysis, identifying potential vulnerabilities and providing recommendations for remediation. It is important to note that risk analysis is limited to configuration analysis and does not include vulnerability scanning at the application or OS level. Tufin Network Security Visibility and Control – this is what allows you to see the whole picture.

Tufin SecureTrack Features:

• Network visualization: Displaying network topology and traffic in real-time.
• Risk analysis: Identifying vulnerabilities and weaknesses in network configuration.
• Compliance auditing: Automatically checking compliance with PCI DSS, HIPAA, GDPR, and other standards.
• Reporting: Creating customizable reports on the state of network security.

Tufin SecureChange: Automation and Change Management

Tufin SecureChange automates change management in security policies. It allows organizations to automate the process of requesting, approving, and implementing changes to security policies, reducing the risk of errors and speeding up response times to new threats. Tufin SecureChange also integrates with various IT Service Management (ITSM) systems, providing seamless integration with existing processes. Full automation requires integration with ITSM and other systems. Tufin network change management – this is a way to avoid routine and errors when changing security rules.

Tufin SecureChange Features:

• Workflow automation: Configuring automated workflows for requesting, approving, and implementing changes to security policies.
• Change impact analysis: Assessing the potential impact of changes to security policies on network security and availability.
• Automated compliance checking: Automatically checking that changes to security policies comply with PCI DSS, HIPAA, GDPR, and other standards.
• Integration with ITSM: Integration with ServiceNow, Remedy, and other ITSM systems.

Tufin SecureApp: Application Security

Tufin SecureApp provides application security in the hybrid cloud. It allows organizations to define and enforce security policies at the application level, providing microsegmentation and protection against application attacks. Tufin SecureApp also integrates with various application development and deployment tools (CI/CD), ensuring security throughout the application lifecycle. Microsegmentation with Tufin allows you to protect each application individually.

Tufin SecureApp Features:

• Microsegmentation: Defining and enforcing security policies at the application level, limiting access between applications and networks.
• Application lifecycle management: Automatically discovering and protecting new applications as they are deployed.
• Integration with CI/CD: Integration with Jenkins, GitLab, and other CI/CD tools.
• Vulnerability analysis: Identifying vulnerabilities in applications and recommendations for remediation.

Practical application of Tufin in the cloud: use cases and examples

Let’s consider several use cases of Tufin to solve specific security problems in the hybrid cloud:

Scenario 1: Automating Firewall Rule Changes in AWS

Imagine that your organization uses AWS to host web applications. Each time developers make changes to applications, it is necessary to manually update the firewall rules in AWS Security Groups. This process is time-consuming, prone to errors, and can lead to delays in application deployment.

With Tufin SecureChange, you can automate this process. Developers can request changes to firewall rules directly from their CI/CD tools. Tufin SecureChange automatically analyzes the request, checks it for compliance with security policies, and, if necessary, approves and implements the change. This type of security task automation significantly speeds up development.

Scenario 2: Ensuring PCI DSS Compliance in Azure

If your organization processes payment cards, it must comply with the PCI DSS standard. This means that you must regularly check your systems for compliance and provide evidence of compliance to auditors.

Tufin SecureTrack can help you ensure PCI DSS compliance in Azure. It automatically checks the configuration of your network and systems for compliance with PCI DSS and generates detailed compliance reports. This greatly simplifies the audit process and reduces the risk of non-compliance.

Scenario 3: Microsegmentation of Applications in GCP

To protect your applications from attacks, you need to microsegment your network, limiting access between applications and networks. Tufin SecureApp allows you to easily create and enforce microsegmentation policies in GCP. You can define access rules at the application level, limiting traffic to only the necessary ports and protocols. This significantly reduces the risk of attacks and increases the overall security of your infrastructure.

Tufin integration with cloud platforms allows you to effectively solve problems of varying complexity.

Integration of Tufin with Other Security Solutions

Tufin integrates with a wide range of other security solutions, extending the security capabilities of your hybrid cloud infrastructure.
