|Issue||Cannot login to the RSA NetWitness Informer UI and the error "Unable to Validate Data" is displayed.|
When navigating to the Informer web interface, the following error is produced:
Unable to validate data.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
The reason it happens is because FIPS compliance templates have been applied to the Informer appliance. ASP.NET 2.0 uses the RijndaelManaged implementation of the AES algorithm when it processes view state data. The RijndaelManaged implementation has not been certified by the National Institute of Standards and Technology (NIST) as compliant with the Federal Information Processing Standard (FIPS). Therefore, the AES algorithm is not part of the Windows Platform FIPS validated cryptographic algorithms and web pages are not served correctly.
Due to AES being uncertified, the Informer Web which uses SHA1/AES, must be adjusted to use TripleDES for this encryption/decryption of state information. Follow the below steps to fix this situation.
1. Login to the Informer appliance via Remote Desktop
Enabled = 1
3. Next open the web.config file in Notepad.
C:\inetpub\wwwroot\NwReporterWeb\web.config or D:\inetpub\wwwroot\NwReporterWeb\web.config
4. Find <system.web> and add the following lines.
<machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="3DES" decryption="3DES" />
5. Save the web.config file and restart IIS. Open a command prompt and type:
Start -> All Programs -> Administrative Tools -> Internet Information Services Mananger
9. Close IIS Manager and restart the Informer Service via the desktop icons.
10. Once the Informer Service restarts browse to the Informer web site and login as normal.
