Security considerations for TrueSight Capacity Optimization
TrueSight Capacity Optimization can securely transfer data between internal components and from TrueSight Capacity Optimization components to external components.
Browser to Application Server
When HTTPS option is chosen
Application Server to Database
When transport layer security is chosen
ETL to data source
Where the data source supports secure transfers
ETL to Data Hub (control)
When HTTPS option is chosen
ETL to Data Hub (data)
When HTTPS option is chosen
SMTP send for email
When SMTP is configured over TLS
LDAP connection for authentication
When LDAP is configured for encryption
The ETL Engine Server and the Data Hub on the Application Server, which communicate with each other over REST APIs, by default use basic authentication to identify themselves. This traffic can optionally be encrypted by configuring them to use HTTPS as mentioned in the preceding table.
For information about the secure protocols TrueSight Capacity Optimization uses for data transfer, see Communication ports and protocols.
User authentication and authorization
TrueSight Presentation Server and Remedy Single Sign-On (SSO) are the key components in the user authentication and authorization flow for accessing TrueSight Capacity Optimization. For information on how these components communicate with each other and the required ports, see Communication ports and protocols.
|TrueSight Presentation Server hosts the web-based TrueSight console and performs functions such as role-based access control and data management functions such as storage and persistence.||TrueSight Presentation Server overview|
|TrueSight Presentation Server and TrueSight Capacity Optimization supports integration with Remedy Single Sign-On (SSO), which enables users to present credentials once for seamless access to all BMC products integrated into the system.|
Users assigned an administrator role can configure user authentication (provided through Remedy SSO) and role-based access control from the TrueSight Capacity Optimization console.
|User authorization is defined by access control policies that allow granular control over functions and data access for TrueSight Capacity Optimization users.||Managing access control|
You can access the TrueSight Capacity Optimization console only if the following conditions are met:
- You have configured the same Remedy SSO server that is configured with the TrueSight Presentation Server
- Both Remedy SSO server and the Presentation Server are up and running as Remedy SSO provides user authentication and Presentation Server provides the authorization details.
The following types of credentials are stored in an encrypted form:
- TrueSight Capacity Optimization user credentials
- All credentials used by connectors (for example, to access data sources such as databases), which are saved in the TrueSight Capacity Optimization database configuration tables
- SMTP email credentials
For credentials used by connectors, these are extracted by the ETL Engine server from the database in encrypted form. If the ETL Engine is configured as a "remote" ETL Engine, then these credentials are extracted by the Data Hub and transferred to the ETL Engine in encrypted form. Thus, in either case, these keys are never transferred in plaintext.
The encryption and decryption keys are pre-configured in all TrueSight Capacity Optimization ETL Engine servers. These keys are not visible to the administrator.
User credentials for ETL modules
The ETL Engine uses a new version of the Java runtime, JRE 1.8, and can connect securely to external data sources, such as VMware vCenter module. This version of JRE requires high security connections and disables RSA keys less than 1024 bits. However, if you have data sources (for example, vCenter) that still have an SSL key and do not respect this security constraint, old SSL keys may have been created with a key of less than 1024 bits.
In this case, the TrueSight Capacity Optimization connector running in the ETL Engine will not be able to create a secure connection and will fail. The correct way to fix this error is to change the SSL key of the data source and restart the scheduler for the ETL task. You will need to refer to the documentation of the data source in your setup for details.
As a workaround (not recommended) the TrueSight Capacity Optimization administrator can follow the steps given below to lower the security policy of the ETL Engine’s JRE.
- Navigate to the file
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024with
- Save the file.
Example for vCenter Extractor Service - An error code (
BCO_ETL_FAIL113) is displayed when the ETL is unable to connect to the vCenter because the server certificate does not conform to expected JVM security constraints. Change the vCenter SSL key to use a self-signed certificate and restart the scheduler for the ETL task. For more information, refer to the
If it is not possible for the TrueSight Capacity administrator to change the SSL certificate of the vCenter, use the general workaround described above.
Important actions are audited in an audit log for the administrator to view. For example, user logins, executions of background tasks, and so on. For more information about the auditing feature, see Auditing.
Web access security
TrueSight Capacity Optimization is designed to be used in an enterprise network, not on the public Internet. Web access vulnerabilities are mitigated by the following steps:
- Cookies: Only session cookies are used; no persistent cookies are left on browser machines.
- Hidden fields: These are used for user data submission, but not for storing data.
