Upgrade DPA 9.1.85 to DPA 10.0.352, 9.1.8510.0.352
The upgrade of SolarWinds DPA is actually very simple. Here we will introduce the process of upgrading from DPA 9.1.95 to DPA 10.0.352. Why upgrade? The emails sent by DPA to users have been clearly written (as shown below). DPA 10.0 has started to support MySQL, and it has fixed some bugs, performance improvement.

Use SFTP instead of FTP to transfer filesFTP (file transfer protocol) is a widely used method for transferring files over the network. However, it is also vulnerable to network eavesdropping, because it also transmits user authentication in plaintext
Information. In fact, the SSH software package already contains a Secure file transmission subsystem called SFTP (Secure FTP).

Configuring users to log on to the switch via HTTP Web managedBecause ENSP can't emulate HTTP login, it's just a little bit simpler.The configuration tasks for the entire HTTP login method are as follows:1. Upload and Load Web page files: Before enabling the HTTP service feature, you need to make sure that the Web page file is already loaded on the switch.2. Configure the SSL policy and load the digital certificate: Perform this configuration task only if you need to reload the SSL certificate.3

Spectre Meltdown vulnerability patch repair security tips
Spectre/Meltdown events seem to have entered the second stage-various vendors have released their own repair solutions. However, it does not seem as smooth as imagined. The industrial control system vendor Wonderware said that the Meltdown patch affected the stability of the industrial control system, while the SolarWinds found that the patch caused a soaring CPU usage.
