Web developers implement several key measures to ensure website security:
SSL Certificates: By using Secure Socket Layer (SSL), data transferred between the user's browser and the server is encrypted.
Regular Updates: Keeping software, plugins, and third-party tools updated helps patch known vulnerabilities.
Firewalls: Web application firewalls filter and monitor HTTP traffic between a web application and the internet.
SQL Injection Protection: Using parameterized queries ensures that malicious input isn’t executed in the database.
Cross-Site Scripting (XSS) Protection: Validating and sanitizing user input prevents scripts from running in the user's browser.
Password Protocols: Employing strong password policies and using hashing algorithms protects user credentials.
Regular Backups: Periodic backups ensure that in the event of a cyber-attack, data can be restored.
By employing these methods, web developers build a robust defense against potential cyber threats.
