DB2 must disable network functions, ports, protocols, and services deemed by the organization to be nonsecure, in accord with the Ports, Protocols, and Services Management (PPSM) guidance.
Severity | Group ID | Group Title | Version | Rule ID | Date | STIG Version |
|---|---|---|---|---|---|---|
| medium | V-213726 | SRG-APP-000383-DB-000364 | DB2X-00-008300 | SV-213726r879756_rule | 2023-06-11 | 2 |
Description
Use of nonsecure network functions, ports, protocols, and services exposes the system to avoidable threats.
ℹ️ Check
Run the following command to find the value of the network service:
$db2 get dbm cfg
TCP/IP Service name (SVCENAME)
SSL service name (SSL_SVCENAME)
If the port numbers are not specified, look for the port numbers in services file and find the port numbers defined for the TCP/IP service name and SSL service name (SVCENAME, SSL_SVCENAME) above.
Default Location for services file:
Windows Service File: %SystemRoot%\system32\drivers\etc\services
UNIX Services File: /etc/services
If the network protocols and ports found in previous step are not in as per PPSM guidance, this is a finding.
✔️ Fix
Use the following commands to set the protocol and ports as per PPSM guidance:
$db2 update dbm cfg using svcename [service_name | port_number]
$db2 update dbm cfg using ssl_svcename [ssl_service_name | port_number]
