Alan Adı Güvenliği

All measures protecting domain names from unauthorized access or modification.

Domain Shadowing

Attack creating malicious subdomains under a legitimate domain after compromising its registrar account.

DNS Rebinding

Attack that tricks browsers into accessing internal network resources by rapidly changing a domain's DNS resolution.

Certificate Transparency (CT)

Open standard requiring all TLS certificates to be recorded in public, auditable logs for transparency and abuse detection.

HSTS Preloading

Submission of a domain to browser preload lists ensuring HTTPS-only access from the very first connection.

DANE (DNS Tabanlı Adlandırılmış Varlıkların Kimlik Doğrulaması)

Protocol using DNSSEC-signed TLSA records to bind TLS certificates to domains, bypassing traditional CA trust.

RPZ (Yanıt Politikası Bölgesi)

DNS firewall mechanism allowing resolvers to block or redirect queries for domains on threat intelligence lists.

Alan Adı Yönlendirmesi (Domain Fronting)

Technique hiding traffic's true destination by using a trusted domain's CDN infrastructure to route encrypted requests.

Email standard enabling verified brand logos in inboxes, requiring DMARC enforcement and a Verified Mark Certificate.

Alan Adı İtibarı

Score assigned to a domain based on abuse history, email behavior, and content signals used by filters and security systems.
