Suspicious TOR Gateway

Detects suspicious TOR gateways. Gateways are often used by the victim to pay and decrypt the encrypted files without installing TOR. Tor intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult.

Go to the intake page and create a new intake from the Zscaler ZIAformat.

Forward events with NSS Servers

Prerequisites

You must have an internal log concentrator to forward events with NSS servers.

Configure the forwarding

In the Zscaler ZIA console:

  1. Go to Administration > Cloud Configuration > Nanolog Streaming Service menu
  2. Select the NSS Feeds tab nanolog
  3. Select Add NSS Feed for each log type you want to forward
  4. In the modal, type a name for the feed, select the NSS Server, and then select the Enabledstatus
  5. In the SIEM IP Address field, enter the IP address of the log concentrator
  6. In the SIEM TCP Port field, enter the port of the log concentrator
  7. Select the desired log type
  8. Select Custom as the Feed Output Type. When possible, fill the Feed Escape Character input with the characters ,\"

  9. For Feed Output Format, paste the following format according to the log type:
