1 Understanding Oracle Privileged Account Manager

This chapter introduces you to Oracle Privileged Account Manager. The topics in this chapter include

1.1 What is Oracle Privileged Account Manager?

Oracle Privileged Account Manager manages privileged accounts that are not being managed by any other Oracle Identity Management components.

Accounts are considered "privileged," if they can access sensitive data, can grant access to sensitive data, or can both access and grant access to that data. Privileged accounts are your company's most powerful accounts and they are frequently shared.

Accounts come under Oracle Privileged Account Manager's purview if they are associated with elevated privileges, are used by multiple end-users on a task-by-task basis, and must be controlled and audited.

For example, these accounts require security and may fall under compliance regulations:

Administrators determine which accounts are privileged within a particular deployment, and they must configure Oracle Privileged Account Manager to manage those accounts.

While Oracle Privileged Account Manager most commonly manages shared and elevated privileged accounts, administrators can also use it to manage passwords for any type of account. For example, if an employee is on extended leave and you have a business reason for allowing another employee to access the system using that person's email account, Oracle Privileged Account Manager can manage that privilege.

1.2 Why Use Oracle Privileged Account Manager?

Oracle Privileged Account Manager enables you to administer and provide better security for privileged accounts and passwords that are traditionally difficult to manage for several reasons.

First, privileged accounts generally have more access rights than a regular user's account. Because these accounts are not typically associated with one specific employee, they are often difficult to audit with existing tools and processes. Consequently, when employees leave the company, they might retain privileged account passwords that are still in use, which is a very serious compliance and security issue.

Also, changing privileged account passwords on a regular basis is difficult. If many people depend on the account, changing the password and notifying everyone requires a coordinated effort.

Finally, you typically do not want to store passwords in a central or well-known location, such as an external repository (like LDAP) or in application configuration files, because you cannot control access to those passwords.

Oracle Privileged Account Manager delivers a complete solution for securely managing privileged accounts and passwords because it provides

1.2.1 Features

Oracle Privileged Account Manager's key features include:

  • Multiple access points, including the Oracle Privileged Account Manager web-based user interface (called the Console), RESTful APIs, and Oracle Privileged Account Manager's command line tool (CLI)

    Oracle Privileged Account Manager's simple RESTful APIs can access Oracle Privileged Account Manager functionality from applications and scripts.

  • Administrator and Self-Service user interfaces that are accessed from Oracle Privileged Account Manager's web-based user interface

  • Integration with Oracle technologies, including

    • Oracle Platform Security Services (OPSS) Policy Store for storing metadata and authorizing functionality

    • Oracle Platform Security Services (OPSS) Trust Service to authenticate and propagate identities from the Oracle Privileged Account Manager user interface to the Oracle Privileged Account Manager server

    • Credential Store Framework (CSF) to securely store passwords to target systems and privileged accounts, and to enable regular updates to application privileged account passwords for compliance, with no changes to applications running in Oracle WebLogic Server (WLS)

    • Identity Connector Framework (ICF) to connect to targets and to discover, update, or discover and update the passwords for privileged accounts on those systems

    • Oracle Wallet to manage public key security

  • Support for multiple target types; including operating systems, databases, LDAP directories, and Oracle Fusion Middleware applications

    In addition, because ICF is an open standard, you can write your own connectors against other types of targets for which Oracle has not yet created an ICF connector.

    For more information about ICF and about developing your own connector, see "Understanding the Identity Connector Framework" and "Developing Identity Connectors Using Java" or "Developing Identity Connectors Using .Net" in the Oracle Fusion Middleware Developer's Guide for Oracle Identity Manager.

  • Advanced reporting capabilities

    • Oracle Privileged Account Manager's out-of-the box audit reports are integrated with Oracle Business Intelligence Publisher 11g (BI Publisher) so you know who is using your privileged accounts. BI Publisher also enables you to create and manage formatted reports from different data sources.

    • The Oracle Fusion Middleware Audit Framework logs audit events in a centralized database. Oracle Privileged Account Manager uses these events to generate audit reports.

    • Events related to privileged account access roll up into Oracle Identity Manager and Oracle Identity Analytics for audit and attestation.

  • Policy-driven access to privileged accounts

  • Ability to manage attended (a person is present) and unattended (no person is present) accounts

    An unattended account, also called a service account, is an account that Oracle Privileged Account Manager uses when it connects to a target system. For example, this is the account and password you must provide when adding and registering a new target system.

    Oracle Privileged Account Manager uses service accounts to perform all Oracle Privileged Account Manager-related operations (such as discovering accounts, resetting passwords, and so forth) on that system, which is why service accounts must have some special privileges and properties. End users are not expected to ever use service accounts.

1.2.2 Functionality

In addition to the functionality described in Section 1.2, "Why Use Oracle Privileged Account Manager?," Oracle Privileged Account Manager

  • Associates privileged accounts with targets

  • Grants users and roles access to privileged accounts, and removes that access

  • Provides role-based access to passwords maintained in the Oracle Privileged Account Manager password request system

  • Provides password check out and check in to control access to accounts

  • Eliminates the potential of having unmanaged privileged accounts when your unattended applications use client-certificate authentication

  • Resets passwords to a random value on check in and check out by default

    You can configure Oracle Privileged Account Manager to automatically check in privileged accounts after a specified time to protect against users who check out that privileged account and do not bother to explicitly check in the account.

    You can also constrain how long users can check out a privileged account.

  • Manages password resets on supported targets

  • Makes authorization decisions to determine

    • Which targets, privileged accounts, and policies are exposed to an end user or administrator

    • Which operations (add, modify, check-in, and check-out) end users and administrators can perform

  • Associates policies with privileged accounts

  • Performs and supports Create, Read, Update, Delete, and Search (CRUDs) operations on targets, privileged accounts, and policies

    This core functionality is exposed through Oracle Privileged Account Manager's RESTful APIs. Check ins, check outs, and so forth are also supported through the RESTful interface.

  • Uses Oracle's common auditing, logging, and reporting to monitor and report access

  • Oracle Privileged Account Manager offers multiple high availability capabilities

As you examine this figure, it is important to note the following points:

1.2.4 Oracle Privileged Account Manager-Managed CSF Credentials

The Credential Store Framework (CSF) is an OPSS component that primarily provides secure storage for credentials. For example, many applications use CSF as a mechanism for storing application credentials.

Oracle Privileged Account Manager enables administrators to identify account credentials to be secured, shared, audited, and managed. In addition, Oracle Privileged Account Manager supports account lifecycle management activities such as periodic password modification.

Though many application developers use CSF to store application credentials for required targets (such as RDBMS and LDAP), there are certain aspects about how CSF is used that can potentially be improved, including:

  • Applications storing their credentials in CSF do not expect these credentials to be shared. Therefore, a given instance of CSF can have multiple references to the same credential. For example, multiple applications could be relying on the same physical credential and yet have multiple logical references.

  • Periodically modifying application credentials is necessary to satisfy compliance and internal IT policy requirements. However, modifying credentials (on the target and thereafter the CSF reference) remains a manual task, which is further complicated by the fact that there may be multiple references to the same credential in CSF. So, you must change the password or credential on the target and then manually update all references to that password in CSF.

    Oracle Privileged Account Manager can automate this process, but automating the periodic modification of credentials is also complicated by the potential for multiple references that cannot be accurately traced.

Oracle Privileged Account Manager leverages its account lifecycle management feature to empower lifecycle management of application credentials stored in CSF.

1.2.4.1 Provisioning

If you decide that Oracle Privileged Account Manager will manage a particular account credential, then that credential must be provisioned through Oracle Privileged Account Manager. The following figure illustrates this provisioning process.

Figure 1-2 Oracle Privileged Account Manager Provisioning Process

Figure illustrating OPAM's provisioning process

The administrator

  1. Adds an Oracle Privileged Account Manager target (if required).

  2. Adds the Oracle Privileged Account Manager privileged account or credential to the target, which must include the necessary CSF mappings.

    Note:

    CSF mappings are the mechanism by which a specific credential instance is uniquely identified within CSF.

    The Oracle Privileged Account Manager server stores the CSF mappings along with its representation of the Privileged Account. The Oracle Privileged Account Manager server creates instances of the credential in CSF that correspond to the provided mappings.

1.2.4.2 Lifecycle Management

An account provisioned as described in Section 1.2.4.1, "Provisioning" can have an associated Password Policy that governs password construction, periodic modification requirements, and so forth.

Oracle Privileged Account Manager normally honors and performs actions on the policy. However, whenever an administrator modifies an account credential that has associated CSF-mappings, Oracle Privileged Account Manager also updates the credential instances stored in CSF with those mappings. This update ensures that all relevant parties have access to the latest credential and allows the seamless management of password lifecycle events such as periodic modification.

1.2.4.3 Application Consumption

Using Oracle Privileged Account Manager to manage an application's credentials places no additional burden on that application. The only process change that occurs is that the credential must first be provisioned through Oracle Privileged Account Manager into Oracle Privileged Account Manager and CSF.

Oracle Privileged Account Manager pushes the credential to CSF with the administrator-provided mappings. If those mappings remain constant, the application can continue to access the credentials directly through CSF.
