Verify integrity of downloaded files by GPG signature verification
Verify that a Linux RPM package file is signed by Dell Technologies and has not changed since the signing.
Prerequisites Ensure that you have access to Linux system.
About this task Linux RPM uses GPG to sign packages. GPG does not rely on a network of Certificate Authorities (CA), but on individual signatures and peer trust. To verify the signature of an RPM, you must first import the Dell OpenManage Enterprise Power Manager public key into the GPG keyring, and then verify the RPM.
Steps 1. Download the Power Manager artifacts to a Linux server from the following location: Artifacts. 2. Open a terminal window or shell session. 3. Change the directory to the location where the files are downloaded. 4. Extract the files using the following command:
tar -xf ome_powermanager_1.(3.3.0).tar.gz
The RPM files are displayed. 5. Verify the signature of each RPM package by running the following command:
rpm --checksig -v package
Where the package is the package file name. For example,
rpm --checksig -v dell-pmp-business-powermgrgrpext-3.3.0.82-1.x86_64.rpm

If the Dell OpenManage Enterprise Power Manager public key is not added to the keyring of the system, the following output
is displayed:
Header V4 RSA/SHA1 Signature, key ID 19b55d20: NOKEY Header SHA1 digest: OK V4 RSA/SHA1 Signature, key ID 19b55d20: NOKEY MD5 digest: OK
The NOKEY messages indicate that the Linux system does not recognize the signing key.
6. Save the following Dell OpenManage Enterprise Power Manager public key in a text file on Linux system. Ensure that no
additional characters are added to or removed from the key.

7. Import the public key using the following command: rpm --import keyfile
Where keyfile is the text file which has the public key. 8. After importing the key, verify the RPM package files for a valid signature by running the following command:
rpm --checksig -v package
Where the package is the package file name. For example,
rpm --checksig -v dell-pmp-business-powermgrgrpext-3.3.0.82-1.x86_64.rpm
. The following response confirms that the files are signed by Dell Technologies and not tampered.
Header V4 RSA/SHA1 Signature, key ID 19b55d20: OK Header SHA1 digest: OK V4 RSA/SHA1 Signature, key ID 19b55d20: OK MD5 digest: OK
The OK messages indicate that the Linux server recognizes that the package is signed by a trusted key. 9. Run the following command to verify all the RPM package files in a directory:
find rpmFileLocation -type f -name \*.rpm -exec rpm --checksig -v {} ';'
where rpmFileLocation is the path where all RPM files exist. For example,
find . -type f -name \*.rpm -exec rpm --checksig -v {} ';'
Security controls map
Power Manager uses fine-grained instrumentation to provide increased visibility to power consumption, anomalies, and utilization. Power Manager alerts and reports about power and thermal events in servers, chassis, and custom groups consisting of servers and chassis. This reporting enables increased control, faster response times, greater accuracy, and broader decisionmaking intelligence than is otherwise possible.
Figure 1. Security control map for Power Manager plug-in
Authentication
Access control settings provide protection of resources against unauthorized access. Only Administrators, Device Managers, and Viewers have access to Power Manager plug-in features with appropriate roles and privileges that are configured. For feature-based access details, see the OpenManage Enterprise Power Manager and OpenManage Enterprise User's Guide.

Rest API security
For the rest API security-related information, see the Security section in OpenManage Enterprise Power Manager RESTful API Guide.
Login security settings
There are various security configurations available in OpenManage Enterprise which when applied in OpenManage Enterprise gets automatically applied to the Power Manager plug-in. For example, you can provide an IP range where only the devices that are specified in the IP range can access OpenManage Enterprise, block a user by specifying the username or an IP address, or lock a user for a specific duration after multiple failed attempts. For more details, see the Set the login security properties topic in the OpenManage Enterprise User's Guide.
User and credential management
Each user is assigned certain privileges that determine their access level in OpenManage Enterprise. For information about the user roles and feature-based access privileges for OpenManage Enterprise and Power Manager, see the OpenManage Enterprise User's Guide and OpenManage Enterprise Power Manager User's Guide.
Role and scope-based access
Role-Based Access Control (RBAC) defines the user privileges into three categories: Administrator, Device Manager, and Viewer. Scope-Based Access Control (SBAC) enables administrators to limit the device groups that a device manager can access. The following topics further explain the RBAC and SBAC features.
Role-based access control (RBAC) privileges
Users are assigned roles that determine their level of access to the appliance settings and device management features. This feature is termed as Role-Based Access Control (RBAC). The console enforces the privilege that is required for a certain action before allowing the action.
The privileges for the custom roles created by an administrator are assigned at the time the role is created.
The table below lists the privileges of each role.
