Group -
The storage system must implement cryptographic mechanisms to prevent unauthorized modification or disclosure of all information at rest on all storage system components.
Operating systems handling data requiring “data at rest” protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. Selection ...Rule Low Severity -
SRG-OS-000046-GPOS-00022
Group -
SNMP must be changed from default settings and must be configured on the storage system to provide alerts of critical events that impact system security.
Whether active or not, default SNMP passwords, users, and passphrases must be changed to maintain security. If the service is running with the default authenticators, anyone can gather data about t...Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
The SNMP service on the storage system must use only SNMPv3 or its successors.
SNMP Versions 1 and 2 are not considered secure. Without the strong authentication and privacy provided by the SNMP Version 3 User-based Security Model (USM), an attacker or other unauthorized user...Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
The SNMP service on the storage system must require the use of a FIPS 140-2 approved cryptographic hash algorithm as part of its authentication and integrity methods.
The SNMP service must use AES or a FIPS 140-2 approved successor algorithm for protecting the privacy of communications.Rule Medium Severity -
SRG-OS-000355-GPOS-00143
Group -
The storage system must, for networked systems, compare internal information system clocks at least every 24 hours with a server which is synchronized to one of the redundant United States Naval Observatory (USNO) time servers, or a time server designated for the appropriate DoD network (NIPRNet/SIPRNet), and/or the Global Positioning System (GPS).
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...Rule Low Severity

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.
