Network Traffic Analysis

The SC//AcuVigilâ„¢ Network Traffic Analysis application, listed in the App Catalog as Traffic Analysis and known in earlier documentation as Firewall Logger, logs information about every connection made across segments or out through the WAN or backup interfaces. It doesn't log traffic that stays within a segment or that goes across VPN tunnels.

Where to find it

  • For all your sites: from the Apps menu, select Traffic Analysis. The Network Traffic Analysis page holds the company-wide default settings. The page says these values "will appear as the default values when initially configuring the app at a specific location."
  • For one site: on the site's Network tab, the Network Traffic Analysis block shows Logging Mode (for example, FCL), Logs Sent, Logs Failed, Daily Limit, User Dashboard Access, and a Last 24 Hours link, with an Update Configuration link in its header.

Company-wide settings

Setting Description
Enabled Whether logging is turned on by default when the application is set up at a site.

Scale Computing manages these company-wide settings as part of the managed service. To request a change, contact Scale Computing Support.

Levels of service

Level What you get
Basic Logs 50,000 connections each day, starting at midnight local time, and keeps the past seven days of records for analysis. Includes near real-time alerts for anonymous proxy connections.
ESS Raises the connection logging limit and adds Managed Detection and Response (MDR) services.
ESS Plus Adds intrusion detection (IDS) with threat feeds.
ESS PCI Adds intrusion detection (IDS) with threat feeds, for PCI DSS environments.

Viewing connection logs

Connection logs are sent to Sematext or Elastic, depending on the Log Sync setting, and can be viewed in Kibana dashboards. On a site's Network tab, the Network Traffic Analysis block has a Last 24 Hours link and shows whether User Dashboard Access is enabled.

Tips for searching logs

  • New traffic is marked with the log type LN when it enters the firewall. Blocked traffic is also marked LB when it leaves the firewall without matching an allow rule.
  • Every blocked connection has two log entries, one LN and one LB. Because of this, filtering out LB entries doesn't show you only allowed traffic.
  • In Kibana searches, the period (.) and asterisk (*) are both wildcards, but you can use only one wildcard in each search term. For example, id_orig_n:back*PC. returns an error, but id_orig_n:backofficePC. and id_orig_n:back*PC1 return results.

Setting up Network Traffic Analysis

Scale Computing sets up Network Traffic Analysis for you as part of the managed service, matched to your level of Enhanced Security Service (ESS):

  • The Traffic Analysis application and the ESS application for your level of service (ESS Standard, ESS Plus, or ESS PCI) are installed at the site.
  • Logging is enabled in the Network Traffic Analysis block on the site's Network tab, with the daily connection limit for your level of service.
  • ESS Standard uses the ciarmy threat feed. ESS Plus and ESS PCI use IDS mode with every threat feed (ciarmy, et_ips, mandiant, and tor).
