Not signed correctly : The secure. After initially signing a zone, the zone must periodically be re-signed with new keys before the signing key validity period expires, in order to maintain a secure DNSSEC operational status.

The validity period for DNSSEC signing keys should be short enough to maintain security, but long enough to enable easy administration. Validation status : A recursive DNS server with a valid trust anchor public cryptographic key for the secure. Can validate : If the recursive DNS server supports all cryptographic algorithms used to sign the secure.

Similarly, a DNS server that does not currently have a valid trust anchor for the secure. Trust anchors must be updated when a zone is re-signed, for example, during key rollover. If the validation succeeds, it will return the query results to the client.

In this scenario, if the zone is not signed, no validation is attempted and the response is returned normally to the client. If the DNS client is directly querying an authoritative DNS server, the response will always appear to be validated, even if the zone is not signed.

This is because authoritative DNS servers always return authentic responses. This is true even if the zone is not signed. Note : This only applies to queries against a recursive, non-authoritative DNS server. However, if the recursive DNS server is DNSSEC-aware and validation fails, it will return a server failover to the client even if the client does not require validation.

The DNS socket pool makes cache-tampering attacks more difficult because a malicious user must correctly guess both the source port of a DNS query and a random transaction ID to successfully run the attack.

DNS is often subject to various attacks, such as spoofing and cache-tampering. The TrustAnchors zone stores preconfigured public keys that are associated with a specific zone. Note that the current size is 2, When you configure the DNS socket pool, you can choose a size value from 0 to 10, The larger the value, the greater the protection you will have against DNS spoofing attacks.
