Confidentiality of information during transmission is controlled through the use of an approved TLS version.
Transport Layer Security (TLS) encryption is a required security setting as a number of known vulnerabilities have been reported against Secure Sockets Layer (SSL) and earlier versions of TLS. Encr...Rule High Severity -
SRG-APP-000176-DB-000068
Group -
SQL Server must enforce authorized access to all PKI private keys stored/utilized by SQL Server.

SRG-APP-000179-DB-000114
Group -
SQL Server must use NIST FIPS 140-2 or 140-3 validated cryptographic modules for cryptographic operations.

Group -
SQL Server must maintain the authenticity of communications sessions by guarding against man-in-the-middle attacks that guess at Session ID values.
One class of man-in-the-middle, or session hijacking, attack involves the adversary guessing at valid session identifiers based on patterns in identifiers already known. The preferred technique ...Rule Medium Severity -
SRG-APP-000231-DB-000154
Group -
SQL Server must protect the confidentiality and integrity of all information at rest.

Group -
SQL Server must reveal detailed error messages only to documented and approved individuals or roles.

Group -
SQL Server must prevent non-privileged users from executing privileged functions, to include disabling, circumventing, or altering implemented security safeguards/countermeasures.

Group -
SQL Server must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
In order to ensure sufficient storage capacity for the audit logs, SQL Server must be able to allocate audit record storage capacity. Although another requirement (SRG-APP-000515-DB-000318) mandate...Rule Medium Severity -

Group -
SQL Server must provide a warning to appropriate support staff when allocated audit record storage volume reaches 75% of maximum audit record storage capacity.
Organizations are required to use a central log management system, so, under normal conditions, the audit space allocated to SQL Server on its own server will not be an issue. However, space will s...Rule Medium Severity -

Group -
SQL Server must provide an immediate real-time alert to appropriate support staff of all audit log failures.

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.
