The vCenter PostgreSQL service must off-load audit data to a separate log management facility.


Overview

Finding ID Version Rule ID IA Controls Severity
V-259185 VCPG-80-000122 SV-259185r961860_rule Medium
Description
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. The database management system (DBMS) may write audit records to database tables, to files in the file system, to other kinds of local repository, or directly to a centralized log management system. Whatever the method used, it must be compatible with off-loading the records to the centralized system.

By default there is a vmware-services-vmware-vpostgres.conf rsyslog and vmware-services-vmware-postgres-archiver.conf configuration file that includes the service logs when syslog is configured on vCenter but it must be verified.

At the command prompt, run the following command:

# cat /etc/vmware-syslog/vmware-services-vmware-vpostgres.conf

Expected result:

# vmware-vpostgres first logs stdout, before loading configuration
input(type="imfile"
File="/var/log/vmware/vpostgres/serverlog.stdout"
Tag="vpostgres-first"
Severity="info"
Facility="local0")
# vmware-vpostgres first logs stderr, before loading configuration
input(type="imfile"
File="/var/log/vmware/vpostgres/serverlog.stderr"
Tag="vpostgres-first"
Severity="info"
Facility="local0")
# vmware-vpostgres logs
input(type="imfile"
File="/var/log/vmware/vpostgres/postgresql-*.log"
Tag="vpostgres"
Severity="info"
Facility="local0")

If the output does not match the expected result, this is a finding.

At the command prompt, run the following command:

# cat /etc/vmware-syslog/vmware-services-vmware-postgres-archiver.conf

Expected result:

# vmware-postgres-archiver stdout log
input(type="imfile"
File="/var/log/vmware/vpostgres/pg_archiver.log.stdout"
Tag="postgres-archiver"
Severity="info"
Facility="local0")
# vmware-postgres-archiver stderr log
input(type="imfile"
File="/var/log/vmware/vpostgres/pg_archiver.log.stderr"
Tag="postgres-archiver"
Severity="info"
Facility="local0")

If the output does not match the expected result, this is a finding.
