- Basic Concepts
- Ports are numbered addresses for network communication
- There are 65,535 ports, but not all are used daily
- TLS/SSL port is port 443 (HTTPS) for secure connections
- Protocols and Security
- HTTP (port 80) is unsecured protocol for web traffic
- HTTPS is a secure version of HTTP using TLS/SSL certificates
- SSL certificates are now called TLS certificates
- Importance and Benefits
- HTTPS is required for PCI compliance online payments
- SSL ports protect against cybercrime and information theft
- HTTPS pages load faster than HTTP pages
- Implementation
- Default network starts as HTTP
- TLS/SSL certificate installation authenticates organization identity
- Certificate installation enables HTTPS protocol for secure data transfer
