"Firewall Management"

The Firewall Management system allows you to create and configure network security rules to protect your virtual machines. Maximum limit: 25 firewalls per account.

The Firewall page displays your existing firewalls with detailed information (6 firewalls per page):

Firewall Information Display

Detailed Firewall Information

Each firewall displays comprehensive details:

Basic Information

Configuration Summary

Operational Metrics

Essential Details

Name: User-defined firewall identifier

Description: Optional purpose description

Region: Geographic deployment location

Status: Current operational state

Creation Date: When firewall was created

Security Rules Timing

Rule Application Process

Rule Creation

New rules are validated and saved to firewall configuration

Configuration Propagation

Rules are distributed to network infrastructure (up to 10 minutes)

Traffic Filtering

Rules become active and begin filtering network traffic

Monitoring and Validation

Test connectivity and validate rule effectiveness

Firewall Management Best Practices

Security Design Principles

Defense in Depth

Principle of Least Privilege

Documentation and Compliance

Operational Best Practices

Planning and Design

Map application network requirements before creating rules

Design firewall architecture for scalability

Plan for different environments and use cases

Consider compliance and regulatory requirements

Implementation

Start with restrictive rules and open access gradually

Test rules in development environment first

Document all rules with clear descriptions

Implement changes during maintenance windows

Monitoring and Maintenance

Monitor firewall effectiveness and performance

Regular security audits and rule reviews

Update rules based on changing requirements

Remove obsolete or unused rules promptly

Incident Response

Plan for security incident response procedures

Maintain emergency access procedures

Document escalation and communication procedures

Regular disaster recovery testing

Firewall Integration

Integration with VM Workflow

VM Deployment

Deployment Integration

Attach firewalls during VM creation

Configure security rules before going live

Test connectivity after deployment

Monitor security effectiveness

Application Deployment

Application Integration

Configure rules for specific applications

Plan for application update requirements

Test application functionality with firewall rules

Monitor application performance impact

Automation and Scaling

Scaling Considerations

Common Firewall Scenarios

Web Application

Database Server

Development Environment

Production Environment

Web Server Firewall

Purpose: Protect web servers and applications

Common Rules: HTTP (80), HTTPS (443), SSH (22)

Considerations: Load balancer integration, CDN compatibility

Monitoring: Web application performance and security metrics
