💡 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.
💡 Subdomain Takeover Vulnerabilities
Subdomain takeover occurs when DNS records point to decommissioned services. Attackers claim the abandoned resource and serve content under the trusted domain, enabling cookie theft, phishing, and reputation damage.
