Group -
The Key Signing Key (KSK) rollover interval must be configured to no less than one year.
The DNS root key is a cryptographic public-private key pair used for DNSSEC signing of the DNS root zone records. The root zone KSK serves as the anchor for the “chain of trust” that enables DNS re...Rule Medium Severity -
SRG-APP-000215-DNS-000003
Group -
The Infoblox system implementation must enforce approved authorizations for controlling the flow of information between DNS servers and between DNS servers and DNS clients based on DNSSEC policies.
A mechanism to detect and prevent unauthorized communication flow must be configured or provided as part of the system design. If information flow is not enforced based on approved authorizations, ...Rule Medium Severity -
SRG-APP-000215-DNS-000026
Group -
A DNS server implementation must provide the means to enable verification of a chain of trust among parent and child domains (if the child supports secure resolution services).
If name server replies are invalid or cannot be validated, many networking functions and communication would be adversely affected. With DNS, the presence of Delegation Signer (DS) records associat...Rule Medium Severity -

Group -
Infoblox DNS servers must protect the authenticity of communications sessions for zone transfers.
DNS is a fundamental network service that is prone to various attacks, such as cache poisoning and man-in-the middle attacks. If communication sessions are not provided appropriate validity prote...Rule Medium Severity -

Group -
Infoblox DNS servers must be configured to protect the authenticity of communications sessions for queries.
The underlying feature in the major threat associated with DNS query/response (i.e., forged response or response failure) is the integrity of DNS data returned in the response. An integral part of ...Rule Medium Severity -

SRG-APP-000246-DNS-000035
Group -
The Infoblox system must be configured to restrict the ability of individuals to use the DNS server to launch Denial of Service (DoS) attacks against other information systems.
A DoS is a condition where a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. Individual...Rule Medium Severity -

Group -
The Infoblox system must be configured to manage excess capacity, bandwidth, or other redundancy to limit the effects of information flooding types of Denial of Service (DoS) attacks.
A DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. In the ca...Rule Medium Severity -
SRG-APP-000268-DNS-000039
Group -
The Infoblox system must be configured to activate a notification to the system administrator when a component failure is detected.
