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] Note: http://www.ibm.com/support/knowledgecenter/en/SSEPGG_10.5.0/com.ibm.db2.luw.admin.sec.doc/doc/t0025241.html
