SSL/TLS Encryption

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) encrypt communications between browsers and web servers.

Benefits include:

• Protection against data interception
• Improved user trust
• Better search engine rankings
• Compliance with security standards

Websites should always use HTTPS rather than HTTP.

Secure APIs

Application Programming Interfaces (APIs) must be protected using:

• Authentication tokens
• Encryption
• Access controls
• Rate limiting

API vulnerabilities are increasingly targeted by attackers.

Regular Software Updates and Patch Management

Outdated software is a major source of website vulnerabilities.

Update Core Systems

Regularly update:

• Content Management Systems (CMS)
• Web applications
• Server operating systems
• Database software
