SM Agent Authentication Test

This test tracks every critical step in the request authorization cycle of a Web agent, beginning with the Web agent's attempt to login to the Policy server, through the request validation process, and finally, authorization. In the process, it indicates if any serious errors/failures have occurred at any stage.

Target of the test : A SiteMinder Policy server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Web agent that reports measurements to the OneView Monitor on the Policy server.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the Policy server for which this test is to be configured.

Port

Refers to the port at which the Policy server listens to.

SNMPPort

The port at which the monitored target exposes its SNMP MIB; The default value is 161.

SNMPVersion

By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the SNMPversion list is v1. However, if a different SNMP framework is in use in your environment, say SNMP v2 or v3, then select the corresponding option from this list.

SNMPCommunity

The SNMP community name that the test uses to communicate with the firewall. This parameter is specific to SNMP v1 and v2 only. Therefore, if the SNMPVersion chosen is v3, then this parameter will not appear.

UserName

This parameter appears only when v3 is selected as the SNMPVersion. SNMP version 3 (SNMPv3) is an extensible SNMP Framework which supplements the SNMPv2 Framework, by additionally supporting message security, access control, and remote SNMP configuration capabilities. To extract performance statistics from the MIB using the highly secure SNMP v3 protocol, the eG agent has to be configured with the required access privileges – in other words, the eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB. Therefore, specify the name of such a user against this parameter. 

Context

This parameter appears only when v3 is selected as the SNMPVersion. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the SNMPEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName). If the Username provided is associated with a context name, then the eG agent will be able to poll the MIB and collect metrics only if it is configured with the context name as well. In such cases therefore, specify the context name of the Username in the Context text box.  By default, this parameter is set to none.

AuthPass

Specify the password that corresponds to the above-mentioned Username. This parameter once again appears only if the SNMPversion selected is v3.

Confirm Password

Confirm the AuthPass by retyping it here.

AuthType

This parameter too appears only if v3 is selected as the SNMPversion. From the Authtype list box, choose the authentication algorithm using which SNMP v3 converts the specified username and password into a 32-bit format to ensure security of SNMP transactions. You can choose between the following options:

  • MD5 – Message Digest Algorithm
  • SHA – Secure Hash Algorithm

EncryptFlag

This flag appears only when v3 is selected as the SNMPversion. By default, the eG agent does not encrypt SNMP requests. Accordingly, the this flag is set to No by default. To ensure that SNMP requests sent by the eG agent are encrypted, select the Yes option. 

EncryptType

If this EncryptFlag is set to Yes, then you will have to mention the encryption type by selecting an option from the EncryptType list. SNMP v3 supports the following encryption types:

  • DES – Data Encryption Standard
  • AES – Advanced Encryption Standard

EncryptPassword

Specify the encryption password here.

Confirm Password

Confirm the encryption password by retyping it here.

Timeout

Specify the duration (in seconds) within which the SNMP query executed by this test should time out in this text box. The default is 10 seconds.

Data Over TCP

By default, in an IT environment, all data transmission occurs over UDP. Some environments however, may be specifically configured to offload a fraction of the data traffic – for instance, certain types of data traffic or traffic pertaining to specific components – to other protocols like TCP, so as to prevent UDP overloads. In such environments, you can instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP). For this, set this flag to Yes. By default, this flag is set to No.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Login calls

Indicates the number of login attempts made by this Web agent during the last measurement period.

Number

 

Login errors

Indicates the number of errors that occurred during the login attempts made in the last measurement period.

Number

An error indicates a communication failure between the Web agent and the Policy server. Therefore, a very high value of this measure could indicate a problem condition requiring investigation.

 

Login failures

Indicates the number of failed login attempts during the last measurement period.

Number

A login attempt can fail if users are not authorized or authenticated by the Policy server.

Login time

Indicates the time taken by the user to log into a resource.

Secs

Ideally, this value should be low.

Validation calls

Indicates the number of times, in the last measurement period, this Web agent attempted to validate a session cookie against the Policy server to authenticate a user, instead of matching the user's credentials to a user directory entry.

Number

The Web Agent creates a session cookie on the user’s browser when a user is successfully authenticated, and uses that cookie to authenticate the user on subsequent requests for new resources.

The following conditions affect this measure:

  • User Session Cache size - If a Web Agent’s user session cache is set to a value greater than 0, the user’s session information is stored in the cache. The Web agent validates the session against the session cache instead of the Policy server, so the value of this measure does not increase. If the user session cache is set to 0, this measure increases each time a user requests a protected resource because the Web agent must validate the session against the Policy Server.
  • Multi-thread vs. Multi-process cache - Web agents that use multi-threaded cache, such as IIS Web Agents, iPlanet 4.x and 6.0 Web Agents (on Windows operating systems, and Domino Web Agents (on Windows and UNIX operating systems), add a session to the session cache (if the session cache size is greater than 0) when a user is successfully authenticated. If that user requests additional resources from the same realm, the Web agent validates the user against the session cache, so the Validation_calls measure does not increase. Apache and iPlanet 4.x and 6.0 Web Agents running on UNIX operating systems, which use multi-process cache, do not add the session cookie to the session cache until the user presents the cookie to the Web agent during a request for another resource in the realm where she was authenticated. The Web agent validates the first request made with a session cookie against the Policy Server, which increases the ValidationCount. Subsequent requests are validated against the cache.

Validation errors

Indicates the number of errors that occurred when this Web agent attempted to validate a user session during the last measurement period.

Number

Errors indicate a communication failure between the Web agent and the Policy server. A high value of this measure therefore, is indicative of a problem.

Validation failures

Indicates the number of times, in the last measurement period, this Web Agent has failed to validate a user session because of an invalid session cookie.

Number

Ideally, this value should be low.

Validation success percent

Indicates the percentage of validation attempts that were successful, currently.

Percent

A high success percentage is an indicator of good health.

Validation time

Indicates the time this Web agent takes to validate a cookie used to authenticate a user.

Secs

Ideally, this value should be low.

Authorization calls

Indicates the number of authorization attempts made by this Web Agent during the last measurement period.

Number

An authorization attempt occurs when a user supplies credentials to the Policy Server in order to access a protected resource.

 

Authorization errors

Indicates the number of errors that occurred during authorization attempts made by this Web Agent during the last measurement period.

Number

An error indicates a communication failure between the Web Agent and Policy Server during an authorization call.

 

Authorization failures

Indicates the failed authorization attempts during the last measurement period.

Number

An authorization attempt fails when a user enters invalid credentials.

 

Authorization success percent

Indicates the percentage of authorization attempts that were currently successful.

Percent

 

Authorization time

Indicates the average time it takes to authorize a user.

Secs

Ideally, this value should be low.
