Network Security
Security Best Practices
- Principle of Least Privilege: Only open ports and allow IPs that are necessary
- Default Deny: Start with restrictive firewall and add rules as needed
- Regular Review: Periodically review and audit firewall rules
Common Firewall Rules
Web Traffic
Allow HTTP (80) and HTTPS (443) from any source for public web access.
SSH Access
Restrict SSH (22) to specific IP addresses for security.
Database Access
Allow database ports only from application servers.
