The Importance of Securing The EM12c
Environment
 IT environments are now more complex and dynamic.
 Financial implications and loss of goodwill coupled with stringent
regulatory requirements.
 Challenges due to introduction of distributed system management
applications.
What best practices are in place for system management products?

Focus on Security Groups, Roles and Auditing
 Creating significant roles and then grant roles to users instead of
granting privileges.
 Take advantage of privilege propagation groups and systems to deter
from resource demands
 Treat the Repository as you would any other database. Use common
sense and standard security best practices.
 Enable auditing to retain information about actions in the repository
and export to an external directory to retain limited information.

Enabling Audit Options
 To enable audit for a subset of audited operations, please use the
following EM CLI verb:
>emcli update_audit_settings -
audit_switch="ENABLE/DISABLE" -
operations_to_enable="<insert operation name here or
just say ALL>" -
operations_to_disable="<insert operation name here or
just say ALL>"
18

Updating Audit Settings
 External file systems can be updated from the repository on a regular
basis to externalize the service.
 Tip- Ensure there is enough disk space for this operation, as log files
can consume significant space.
file_prefix=<file_prefix> -
directory_name=<directory_name> -file_size = <file
size> -data_retention_period=<period
in days>
19

Example of audit data to external directory
 We’ll retain the data in the Repository for 31 days
 Data will be exported to the external directory, (dba_directories)
 Each of the audit files will be prefixed with “em12c_audit”
 Files will be max size of 25M each
externalization_switch=ENABLE -
file_prefix=em12c_audit -
directory=AUD_DMP -file_size=25000000 -
data_retention_period=31
20

Best Practices for Auditing
 Plan carefully to ensure that you capture the data that you require to
audit effectively.
 Use and External audit service and secure the files created to retain
audit data outside the repository in case of significant loss.
