Manage Credentials

This dashboard lists the available lockboxes, the credentials associated with them, and the related information. It allows you to add new and edit existing credentials. Credentials are stored in lockboxes. Lockboxes can be created beforehand, or during the process of creating credentials.

Credential information consists of a name, type, policies, and resource mappings. The credential name uniquely identifies the credential. A range of different types allows you to choose a credential type that suits your organization’s security requirements. A credential type can consist of a user name, password, Windows domain, no input, or the available combinations of these parameters.

A credential can have none, one, or multiple policies. A credential policy defines the number of times a credential can be used, the number of allowed authentication failures, the time range during which the credential is valid, or the length of time the credential data can be cached on the client.

Resource mappings identify secured resources. The mappings typically contain a combination of literal expressions, regular expressions, or an IP address range.

By default, the following columns are displayed:

Edit: Click to edit a credential’s name, properties, resource mappings, or policies.
Lockbox: The name of the lockbox where the credential is defined.
Name: The name of the credential.
Alarms: The total counts of outstanding credential alarms, broken down by alarm types (Fatal, Critical, and Warning).
Valid Until: The date and time at which the credential expires.
Relative Order: The order in which credentials are returned to credential clients.
Type: Shows the credential type. The following credential types are available:
Challenge Response: Uses one or more challenge and response pairs to grant access without requiring any interaction in the browser interface. The answers are sent by the agent and are part of the agent configuration. Use this type for SSH keyboard-interactive credentials.
Domain, User Name, and Password (Windows): Requires a user name and password to access a monitored resource. The domain name is optional.
DSA Key: Uses the Digital Signature Algorithm (DSA) Key for authentication.
RSA Key: Uses the RSA (Rivest, Shamir and Adleman) Key for authentication.
Use Client’s Login At Connection Time: Uses the currently logged in user’s account to access secured resources. This is not the user currently logged into the Management Server, but the user under which the credential client is running. For example, a credential provided to a Foglight Agent Manager instance launched by a user on a remote machine, causes the connection to the secured resource to be made using this user’s identity.
User Name: Requires a user name to access a monitored resource.
User Name and Password: Requires a user name and password to access a monitored resource.
Resource Mappings: Lists one or more resource mapping expressions associated with the credential.
Policies: Lists the policies associated with the credential. Hovering over this column displays a dwell that shows you this information in tabular form.

Credentials are stored in lockboxes. Lockboxes can be created beforehand, or during the process of creating credentials.

Credentials are released to credential clients unencrypted. If the agent uses a standard connection mechanism supported by the Foglight Agent Manager such as WinShell, WMI, or SSH, when a lockbox is released to the Agent Manager, the Agent Manager establishes a connection with the monitored resource, and passes the connection to the agent. If the agent uses a different connection mechanism, the client passes the credential information to the agent. The agent uses this information to establish a connection with secured resources.

When creating a new credential you have an option to start from a blank credential or copy an existing credential. Credential type, policies, and resource mappings are all preserved and copied over to the new credential. Unlike credential name, policies, and resource mappings, once defined, credential types cannot be changed. Copying an existing credential is useful in situations when you need to quickly create a slightly modified version of the existing credential. For example, if your organization enforces periodic password changes, when this happens, simply copy the credential and change its password.

Credentials that are no longer in use can be deleted.

Challenge Response: Uses one or more challenge and response pairs to grant access without requiring any interaction in the browser interface. The answers are sent by the agent and are part of the agent configuration.
Domain, User Name, and Password (Windows): Requires a user name and password to access a monitored resource. The domain name is optional.
DSA Key: Uses the Digital Signature Algorithm (DSA) Key for authentication.
RSA Key: Uses the RSA (Rivest, Shamir and Adleman) Key for authentication.
Use Client’s Login At Connection Time: Uses the currently logged in user’s account to access secured resources. This is not the user currently logged into the Management Server, but the user under which the credential client is running. For example, a credential provided to a Foglight Agent Manager instance launched by a user on a remote machine, causes the connection to the secured resource to be made using this user’s identity.
User Name: Requires a user name to access a monitored resource.
User Name and Password: Requires a user name and password to access a monitored resource.
The credential type depends on the agent that will use the credential to access the monitored resource. For example, some agents support the use of the Use Client’s Login At Connection Time and User Name and Password credential types, while others can only accept the Challenge Response or User Name types. A selected credential type dictates the type and structure of resource mappings associated with a credential. Resource mappings identify the parts of the monitored system that selected agents can access based on their credentials. For example, the User Name and Password credential type, that requires a valid user name and password pair to access a monitored system, can have one or more resource mappings for accessing Unix-based targets based on a condition that evaluates the target port number. Similarly, a credential of the Use Client’s Login At Connection Time type does not require any authentication information, and can have a resource mapping that selects a group of hosts based on their user name. For details about credential types required by specific agents, see the respective cartridge documentation.
For most credential types, the workflow starts with the Credential Properties page open. For other credential types, the workflow can start with a different page.

Resource mappings identify the parts of the monitored system that can be accessed using the credentials in which they are defined. A credential can have one or more resource mappings that include or exclude specific sets of targets. Resource mappings are combined using the logical OR operator. A resource mapping can have one or more conditions, combined using the logical AND operator. Each resource mapping uses a set of predefined building blocks to identify the monitored targets. For example, you can have a credential with multiple resource mappings (one for each usage, for example, if multiple usages exist in the credential type), and each resource mapping can have one or more resource mapping conditions to select secured resources. You can further refine the mapping, if required.

The type and structure of resource mappings depend on the selected credential type, which in turn depends on the range of installed cartridges. Some cartridges, for example, support the Use Client’s Login At Connection Time and User Name and Password credential types, while others can only accept the Challenge Response or User Name types. A Domain, User Name, and Password (Windows) credential type, for example, that requires a valid domain name, user name, and password to access a monitored system, can have one or more resource mappings for accessing Windows-based systems based on a condition that evaluates the target host name.

Usage: Defines the type of the system that is mapped. For example: OS Monitoring by WMI.
Access Resources Using: Identifies the resource component that is evaluated by the resource mapping. For example: Target Host Name, Target Host Address, Target Port, or Is Local Host. Other options may be available.
Equal or Not Equal: Indicates if the targets selected by the matching expression should be included or excluded from the mapping. For example, you can create one resource mapping to select a group of hosts and another to exclude a different set of hosts.
Matching Type: Specifies the condition type. For example, conditions can contain regular expressions or domain names.
TIP: Regular expressions support case insensitive matching when the (?i) flag is used. For example, (?i)host1.example.* returns Host1.example and host1.example.com as matches. Regular expressions run through the JRE Pattern class that supports case insensitivity. For syntax information and usage tips, visit http://rd-www.prod.quest.corp/static/sun_docs/jdk-1_6_0/docs/api/java/util/regex/Pattern.html.
Evaluate This Condition: Indicates if the condition is used during the credential matching.
Matching Values: One or more expressions that are used to scope on the target resource. For example, you can create an expression that defines a host name. Multiple matched values are combined with the logical OR operator, meaning that if one expression evaluates to True, the resource is mapped even though another expression may evaluate to False.

The selections available with each building block in a resource mapping depend on the resource mapping’s Usage type, which in turn depends on the selected credential type and the range of installed cartridges. The selections mentioned above do not reflect the values available with all of the cartridges that support credentials. For information about the available credential types supported by a specific cartridge and the related resource mappings and their building blocks, refer to the cartridge documentation.

When using IPv6 addresses in Credential Mappings it is preferable to use IP Range or CIDR matchers. Since an IPv6 address can have more than one textual representation using String or RegEx matches may lead to confusing server behavior.

When a credential client retrieves a set credentials, the credentials are listed in their relative order. For example, a credential with the order of 100 has operator-level privileges, while another one with the order of 200 has administrative privileges that grants access to a far wider range of resources. Given the order values, any queries that return both credentials retrieve the operator-level credentials first. If you need to retrieve the credential with administrative access first, you can do so by simply changing the relative order of both credentials.

The Reorder Credentials dialog box opens.
To move one credential up or down, use the or buttons in the Move Up and Move Down columns, as required.
3
Click Confirm to close the Reorder Credentials dialog box.

Credential queries help you retrieve credentials using different criteria, such as the target host, a host on which a monitoring agent is running, a credential type, lockboxes to which the credentials belong, and custom properties. You can quickly find out if you can associate existing credentials with monitoring agents rather than create new ones.

The Query Credential dialog box opens.
2
In the Query Credential dialog box, specify the criteria as required.
For example, to look for a credential that can be used to access a specific host using a Domain, User Name, and Password (Windows) credential, in the Query Credential dialog box, type the target host name under Target Host. In the Credential Types table, select Domain, User Name, and Password (Windows).
3
Click Execute.
The Query Credentials dialog box closes and the query results are displayed.

Monitor Alarms

Credential clients generate alarms when certain pre-defined conditions are met. These errors typically happen when a client attempts to access a resource and encounters a policy-related problem. The Monitor Credential Alarms dashboard lists all alarms generated by the existing credential clients and provides additional information about each event. The list includes any alarms generated by the Catalyst Credential Check rule and Credential events generated by the Foglight Agent Manager.

Credential alarms also appear on the main Alarms dashboard, together with other Foglight alarms, while the Monitor Credential Alarms dashboard only lists the alarm generated due to a credential-related condition. Use it to quickly review and manage credential alarms.

For complete information about alarms in Foglight, see the Foglight User Help.

By default, the Monitor Credential Alarms dashboard displays the following columns:

Sev: The alarm severity: Warning , Critical , or Fatal .
Time: The date and time at which the alarm is generated.
Ack’ed: Indicates whether the alarm was acknowledged by the operator: Yes or No.
TIP: Use the Select All or Unselect All buttons to quickly select all alarms, or to clear your selection, as required:
Cleared: Indicates whether the alarm was cleared: Yes or No.
Selecting one or more alarms in the list and clicking Clear allows you to clear the selected alarms.
Instance: The topology object instance against which the alarm is raised.
Message: The alarm message.
Origin: The event that caused the alarm to fire.

To filter the list of alarms, click Alarm Filter in the top right and provide the desired settings.

To view the Credential Alarm dialog box, click any column.

Use this dialog box to find out more about the problem that caused the alarm. From here, click the Diagnostic link to access the part of the browser interface that you can use to further investigate the problem.

Credential queries help you retrieve credentials using different criteria, such as the target host, a host on which a monitoring agent is running, a credential type, lockboxes to which the credentials belong, and custom properties. You can quickly find out if you can associate existing credentials with monitoring agents rather than create new ones.

In a federated environment, Federated Child alarms can be viewed on the Federated Child servers using the above approach. While credentials cannot be administered from the Federation Master, it is possible to view Federated Child alarms from the Alarms dashboard on the Federation Master.

The Credential Alarm dialog box that appears shows a smaller subset of information, containing only the alarm message and the name of the Federated Child server. To retrieve complete information about this alarm, log in to the Federated Child server, navigate to the Monitor Credential Alarms dashboard, and drill down on the alarm to display the common version of the Credential Alarm dialog box.

For complete information about alarms in Foglight, see the Foglight User Help.

Foglight Agent Manager generates credential events based on actions that occur during the processing of credential requests. These events result in the creation of credential alarms of the appropriate severity. The following principles apply:

A connection to the remote host is established.

connection.success

Information

The Agent Manager attempts to establish a connection, but no credentials were retrieved by the credential query.

connection.nocredentials

Warning

Attempt is made to authenticate a connection through the CleartextCredentialService with a credential that is not granted direct access rights.

direct.access.not.assigned

Warning

A lockbox that is associated with a credential is not granted to the Agent Manager Host.

lockbox.not.granted

Warning

The credential used to establish a connection fails to authenticate access to the remote resource.

authentication.failure

Error

A connection to the remote host cannot be established using the retrieved credential.

connection.failure

Error

The Agent Manager cannot process the retrieved credential.

creation.failed

Error

The request to delete an assigned lockbox failed.

lockbox.not.deleted

Error

A credential cannot be used due to a policy violation.

policy.violation

Error

Acknowledging a credential alarm informs other users looking at credential alarms that the alarm is raised due to a known situation. When an alarm is acknowledged, this setting cannot be reverted.

2
Click Acknowledge.
The Acknowledging Alarms progress box appears, indicating that the alarm is being acknowledged.
The Acknowledging Alarms progress box closes, and the Monitor Credential Alarms dashboard refreshes, showing Yes in the Ack’ed column.

In most cases, Foglight clears alarms when the condition that triggered them changes. You can delete certain types of alarms that do not clear themselves if they are no longer relevant.

If the condition that triggered a credential alarm changes, you can manually clear the alarm. For example, a credential alarm fires when an agent fails to connect to a monitored host due to a wrong password. Creating a new credential with the correct password and releasing the new credential to the appropriate credential client remedies the problem, and you can choose to delete the alarm because it is no longer relevant.

When an alarm is cleared, this setting cannot be reverted. You can see a list of cleared alarms using the alarm filter.

2
Click Clear.
The Clearing Alarms progress box appears, indicating that the alarm is being acknowledged.
After a few moments, the Clearing Alarms progress box closes, and the Monitor Credential Alarms dashboard refreshes, no longer showing the newly cleared alarm.

View Clients

The View Clients dashboard lists all credential clients that are registered with the Management Server and provides additional information about each client.

By default, the following columns are displayed:

Alarms: The numbers of Fatal, Critical, and Warning alarms generated against each client, color-coded to indicate the severity.
Name: The name of the credential client.
Client Type: The credential client type. For example, FglAM (Foglight Agent Manager).
Assigned Lockboxes: The name of the lockbox released to the credential client.
Host: The name of the monitored host on which the client is running.

Selecting the check box Show lockboxes currently assigned to each client causes the Credential Client column on the Manage Lockboxes dashboard to be populated. For more information about the Manage Lockboxes dashboard, see Explore the Manage Lockboxes dashboard .
