Cisco web agent download
The following are some examples:. This toast enables the users to know that they have been logged out and that they need to login again to get network access.
You can optionally force logout at machine shutdown default is for users to remain logged in at machine shutdown. You can configure auto-upgrade to be mandatory or optional.
With mandatory auto-upgrade and a newer version of the Agent available from the CAM, existing Agent users will see the following auto-upgrade prompts at login Figure If the upgrade is optional and a newer version of the is Agent available from the CAM, users can choose to Cancel the upgrade and continue with the login process Figure After Agent upgrade and user login, requirement checking proceeds.
After the user submits his or her credentials, the Cisco NAC Agent automatically checks whether the client system meets the requirements configured for the user role Figure If required software is determined to be missing, the Temporary Network Access dialog appears Figure The user is assigned to the Agent Temporary role for the session timeout indicated in the dialog.
The Temporary role session timeout is set by default to 4 minutes and should be configured to allow enough time for users to access web resources and download the installation package for the required software.
When the user clicks Repair , the Cisco NAC Agent dialog for the requirement with the highest priority configured for the user role appears prompting the user to take appropriate action to address the requirement type. For an AS Definition Update requirement Figure , the user clicks the Update button to update the definition files for the Anti-Spyware software on the client system.
For a Windows Update requirement Figure , the user clicks the Update button to set the Windows Update and force updates on the client system if "Automatically Download and Install" is configured for the requirement. Figure Windows Update Requirement Example. For a Launch Program requirement Figure , the user clicks the Launch button to automatically launch the qualified program for remediation if the requirement is not met. Signature verification is done regardless of the setting in the config file for non-Admin.
Figure Launch Program Requirement Example. When the user clicks download, the Save file to dialog appears. The user needs to save the installation file to a local folder, and run the executable file from there. The maximum file size you can make available to users via File Distribution is MB. Figure File Distribution Requirement Example. For a Link Distribution requirement Figure , the user can access the website for the required software installation file by clicking Go To Link.
This opens a browser for the URL specified in the Location field. Figure Link Distribution Requirement Example. Clicking Cancel at this stage stops the login process. For each requirement, the user needs to click Skip to proceed after completing the action required Update, Go To Link, Download.
If met, the Agent proceeds to the next requirement configured for the role. Note If a requirement is Optional , when the user clicks Skip in the Cisco NAC Agent for the optional requirement, the next requirement dialog appears or the login success dialog appears Figure if all other requirements are met.
If a Network Policy page was configured for the role, the following dialog will appear Figure after requirements are met. The user must click the Accept button to successfully log in. When all requirements are met and Network Policy accepted, if configured , the user is transferred from the Temporary role to the normal login role and the login success dialog appears Figure The user is free to access the network as allowed for the normal login role.
Note The administrator can configure the Login and Logout success dialogs to close automatically after a specified number of seconds, or not to appear at all. Once the user clicks the Get Restricted Network Access button, they log into the Cisco NAC Appliance system using a "restricted" user role instead of a more generous standard network access role and are presented with a login confirmation dialog like the one in Figure For more information on enabling restricted network access, see Agent Login.
Figure Restricted Network Access. The logout screen appears Figure If the administrator removes the user from the network, the Login dialog will reappear instead if Popup Login Window is set. If a required software installation requires users to restart their computers, the user should log out of the network before restarting.
Otherwise, the user is still considered to be in the Temporary role until the session times out. The session timeout and heartbeat check can be set to disconnect users who fail to logout of the network manually. This additional interaction is due to the user authentication profile on the RADIUS server, itself, and does not require any additional configuration on the Clean Access Manager.
For example, the RADIUS server profile configuration may feature an additional authentication challenge like verifying a token-generated PIN or other user-specific credentials in addition to the standard user ID and password. In this case, one or more additional login dialog screens may appear as part of the login session. The remote user logs in normally and provides their username and password as shown in Figure Figure Windows Agent Login Dialog.
If the associated RADIUS server has been configured to authenticate users with additional credentials, the user is presented with one or more additional challenge-response dialogs like the password renewal scenario shown in Figure for which they must provide additional credentials to authenticate and connect. Once the additional challenge-response s are validated, the RADIUS server notifies the Clean Access Manager that the user has successfully authenticated and should be granted remote access.
This chapter describes how to configure the Cisco NAC Web Agent to allow users to log in to the network without requiring a permanent, dedicated network access application on the client machine.
When the user terminates the Web Agent session, the Web Agent logs the user off of the network and their user ID disappears from the Online Users list. If requirements are not met, the Web Agent presents a dialog to the user for each unmet requirement. This chapter describes how to configure these requirements.
If users are logging in via the Web Agent in a Windows 7 environment and have proxy connections configured on Internet Explorer, they must enable "Protected Mode" in the browser's security settings to enable Web Agent download on the client machine.
ActiveX runs successfully under these conditions. Note Security restrictions for the "Guest" user profile in Windows Vista operating systems prevent ActiveX controls and Java applets from running properly. By default, Windows Vista checks the server certificate revocation list and prevents the Web Agent from launching on the client machine.
To disable this functionality:. Step 2 Click the Advanced tab. Step 3 Under Security, uncheck disable the Check for server certificate revocation option. Step 4 Click OK. After you have accounted for the above topics, users can log in and gain network access via the Cisco NAC Appliance system according to the parameters and requirements you have defined in your system configuration.
For example, the user may need to acknowledge the installation process redirecting the user to a particular URL destination or approve the Web Agent executable launch following client scanning. Note If the existing CAS certificate is not trusted on the client, the user must accept the optional certificate in the Security Alert dialog that appears before Web Agent launch can successfully proceed.
Otherwise, the user will not be able to use the Cisco NAC Web Agent for login and will either have to contact the Cisco NAC Appliance network administrator to try and help troubleshoot issues with the installation process, or accept "Restricted" network access for the time being until they can fix the Web Agent installation problem.
If both the ActiveX and Java applet Web Agent download and install methods fail, the user sees a notification screen like the one in Figure and is presented with a Windows dialog informing the user that Cisco NAC Web Agent login failed Figure The downloading step in the process can take anywhere from just a few seconds to several minutes, depending on your connection speed. Once the executable files have been downloaded to the client machine's local temporary file directory, the self-extracting installer automatically begins launching the Web Agent on the client machine and the user sees a status window similar to Figure See Figure If the Web Agent scan determines that a required application, process, or critical update is missing, the user receives a "Host is not compliant with network security policy" message Figure through Figure provide a range of examples , is assigned to the Cisco NAC Web Agent Temporary role for the session timeout indicated in the dialog typically 4 minutes by default.
The user can choose to do one or more of the following:. Note The Temporary role session timeout is set to 4 minutes by default, but Cisco recommends you configure the duration to allow enough time for users to access web resources, download installation packages for the required software, and possibly perform other required remediation tasks before attempting to Re-Scan the client machine for compliance.
If the Web Agent scan determines that an optional application, process, or update is missing, the user receives a "Host is compliant with network security policy" message Figure , is assigned to the Cisco NAC Web Agent Temporary role for the session timeout indicated in the dialog typically 4 minutes by default. The user can choose to do one the following:. The reports are available in the following formats:.
Figure Optional Requirement Not Met. If the Web Agent scan determines that the client machine is compliant with the Agent requirements you have configured for the user's role, the user receives a "Host is compliant with network security policy" message within a green banner Figure If the user does not accept the Network Usage Policy, the installation process halts and the user must choose to either restart the install and launch process or accept "restricted" network access.
Note The first time users launch the Cisco NAC Web Agent on a client machine, they will likely see a pop-up blocker message at the top of the browser window after clicking "Accept" to continue past the Network Usage Policy.
Once the user has performed manual remediation and successfully "re-scanned" the client machine, accepted any optional Network Usage Policy, identified and noted optional requirement items, or has chosen to accept "restricted" access for this user login session, the user receives a "Successfully logged on to the network" dialog Figure followed by a Clean Access Authentication browser window Figure featuring Web Agent session status information and a Logout button the user can click to terminate the user session.
It is possible that, even after the Cisco NAC Web Agent launched, installed, and initiated a login session without any issues, or that following manual remediation, the user was able to bring the client machine into compliance and successfully "re-scan" the client, another issue might keep the Cisco NAC Web Agent from logging the user into the network, resulting in a "You will not be allowed to access the network A couple of examples of known causes for this situation is a previous Web Agent session for the same user that did not "tear down" properly, on the CAM or if the user is currently logged into an active Cisco NAC Agent session.
