Secret Store

Using industry best practices, NetMon has been updated to use a secret store to help better protect internal keys and passwords used by the NetMon platform, greatly enhancing the security of the product.

When upgrading to NetMon 5.0.3, the SSL certificate for the web UI is replaced with a new self-signed certificate (SSL). If you customize this SSL, be sure to backup your SSL certificate. For more information, refer to Utilize a Custom SSL Certificate.

DPA rules are disabled during NetMon upgrades. Be sure to take a note of what is enabled before upgrading. For more information, refer to Manage Deep Packet Analytics Rules.
