What’s the difference between DNSSEC and SSL/TLS?

DNSSEC and SSL/TLS protect different things:

DNSSEC:

Protects: DNS record authenticity

Question answered: "Is this DNS data genuine?"

Layer: DNS infrastructure

Does not encrypt, only authenticates

SSL/TLS:

Protects: Connection confidentiality and integrity

Question answered: "Is this connection private and to the right server?"

Layer: Application connection

Encrypts data in transit

Complementary:

DNSSEC ensures you get the real IP address

TLS ensures your connection to that IP is secure

Both together provide stronger security

DNSSEC verifies the map is authentic. TLS protects the cargo during transport.
