What is Web Security?
Web Security is the set of measures, technologies and practices designed to protect web applications, websites and web services from cyber threats, malicious attacks and security vulnerabilities. It is essential for protecting sensitive data, maintaining user trust and complying with data protection regulations.
In today's digital era, where web applications handle personal, financial and critical business information, web security has become an absolute priority. Cyber attacks are increasingly sophisticated and the consequences of a security breach can be devastating for businesses and users.
Web security encompasses multiple layers of protection, from server infrastructure to application code, including protection of data in transit and at rest, robust authentication, granular authorization and continuous threat monitoring.

Frequently Asked Questions about Web Security
Why is web security important?
Protects sensitive data, maintains user trust, meets regulations and prevents financial and reputation losses.
How much does implementing web security cost?
Varies by size and complexity. It's an investment that prevents much higher costs from security breaches.
What is OWASP Top 10?
List of the 10 most critical web vulnerabilities, regularly updated by the security community.
Do I need SSL if my site doesn't handle payments?
Yes, SSL protects any sensitive data and is required by modern browsers and SEO.
How often should I conduct audits?
Minimum annually, but recommended every 6 months or after significant application changes.
What to do if I detect a security breach?
Activate incident response plan, notify authorities if necessary, and communicate to affected users.
