SRG-NET-000362-ALG-000120
Group -
The Sentry must implement load balancing to limit the effects of known and unknown types of Denial-of-Service (DoS) attacks.
If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Load balancing provides service redundancy; which service redundancy reduces the susc...Rule Low Severity -
SRG-NET-000364-ALG-000122
Group -
The Sentry must only allow incoming communications from organization-defined authorized sources routed to organization-defined authorized destinations.
Unrestricted traffic may contain malicious traffic which poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth ...Rule Medium Severity -
SRG-NET-000402-ALG-000130
Group -
The Sentry must reveal error messages only to the ISSO, ISSM, and SCA.
Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can give configuration details about the...Rule Low Severity -
SRG-NET-000510-ALG-000025
Group -
The Sentry providing encryption intermediary services must implement NIST FIPS-validated cryptography to generate cryptographic hashes.
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The network element must implement cryptographic modules adhering to the higher standa...Rule Medium Severity -
SRG-NET-000510-ALG-000040
Group -
The Sentry providing encryption intermediary services must implement NIST FIPS-validated cryptography for digital signatures.
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The network element must implement cryptographic modules adhering to the higher standa...Rule Medium Severity -
SRG-NET-000510-ALG-000111
Group -
The Sentry providing encryption intermediary services must use NIST FIPS-validated cryptography to implement encryption services.
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The network element must implement cryptographic modules adhering to the higher standa...Rule Medium Severity -
SRG-NET-000511-ALG-000051
Group -
The Sentry must offload audit records onto a centralized log server in real time.
Offloading ensures audit information does not get overwritten if the limited audit storage capacity is reached and also protects the audit record in case the system/component being audited is compr...Rule Low Severity
Node 2
The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
