📊 Threat Analysis
The address 72.56.157.3 originates from Moscow, Russia, operating on the network of WS Telecom Inc. It was identified through automated analysis of incoming network traffic across monitored endpoints. During its 17-day observation window, we recorded 343 hostile requests from this IP — roughly 20.2 per day on average. The dual attack vectors of Request Flooding combined with Path Enumeration indicate a coordinated assault rather than opportunistic scanning. Russia currently accounts for 101 blocked IPs in our database, making it a significant source of malicious traffic. At 255/100, this is an extremely high-risk address. All traffic should be considered hostile.

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.
