Security Intelligence

💡 DDoS Mitigation Approaches

Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.

💡 Content Security Policy Implementation

Content Security Policy headers instruct browsers to restrict resource loading, mitigating XSS and data injection attacks. Properly configured CSP policies prevent inline script execution, restrict iframe embedding, and control which domains can serve content.
