Products collecting baselines for anomaly-based detection must have their baselines rebuilt based on changes to mission requirements such as Information Operations Conditions (INFOCON) levels and when the traffic patterns are expected to change significantly.
Administrators should ensure that any products collecting baselines for anomaly-based detection have their baselines rebuilt periodically as needed to support accurate detection. The ISSM is requ...Rule Low Severity -
If a Secure File Transfer Protocol (SFTP) server is used to provide updates to the sensors, the server must be configured to allow read-only access to the files within the directory on which the signature packs are placed.
In a large scale IDPS deployment, it is common to have an automated update process implemented. This is accomplished by having the updates downloaded on a dedicated SFTP server within the managemen...Rule Medium Severity -
Tunneling of classified traffic across an unclassified IP transport network or service provider backbone must be documented in the enclaves security authorization package and an Approval to Connect (ATC), or an Interim ATC must be issued by DISA prior to implementation.
CJCSI 6211.02D instruction establishes policy and responsibilities for the connection of any information systems to the Defense Information Systems Network (DISN) provided transport. Enclosure E ma...Rule High Severity -
Tunneling of classified traffic across an unclassified IP transport network must employ cryptographic algorithms in accordance with CNSS Policy No. 15.
When transporting classified data over an unclassified IP network, it is imperative that traffic from the classified enclave or community of interest is encrypted prior reaching the point of presen...Rule High Severity -
All external connections must be validated and approved by the Authorizing Official (AO) and the Connection Approval Office (CAO) and meeting Connection Approval Process (CAP) requirements.
Every site must have a security policy to address filtering of the traffic to and from those connections. This documentation along with diagrams of the network topology is required to be submitted...Rule Medium Severity
