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 the system and the network(s) and use the information to potentially compromise the integrity of the system or network(s). The product must be configured to alert administrators when events occur that may impact system operation or security. The alerting mechanism must support secured options and configurations that can be audited. Satisfies: SRG-OS-000046-GPOS-00022, SRG-OS-000480-GPOS-00227, SRG-OS-000344-GPOS-00135
Verify a SNMPv3 user account is configured. Run the following command: cli% showsnmpuser Username | AuthProtocol | PrivProtocol 3parsnmpuser | HMAC SHA 96 | CFB128 AES 128 If the output is not displayed in the above format, this is a finding. Identify the SNMP trap recipient and report SNMP configuration with the following command: cli% showsnmpmgr HostIP | Port | SNMPVersion | User <snmp trap recipient IP> | 162 | 3 | 3parsnmpuser If the SNMP trap recipient IP address is incorrect, this is a finding. If the SNMP port is not "162", this is a finding. If the SNMP version is not "3", this is a finding. If the SNMP user ID is incorrect, this is a finding. Generate a test trap: cli% checksnmp Trap sent to the following managers: < IP address of trap recipient> If the response does not indicate a trap was successfully sent, this is a finding.
To configure SNMPv3 alert notifications, use this sequence of operations to create and enable an SNMPv3 user, and create associated keys for authentication and privacy: First, create the "3parsnmpuser" on the host with the following command: cli% createuser 3parsnmpuser all browse Enter the password and retype the password to confirm. Next, create the snmp user and associate that with the "3parsnmpuser" account on the host. cli% createsnmpuser 3parsnmpuser Enter the password and retype the password to confirm. Finally, add the IP address of the SNMPv3 trap recipient, where the permissions of the account are used: cli% addsnmpmgr -pw <password> -version 3 -snmpuser 3parsnmpuser <ip address>
