How does Network Security Monitoring work?
The network traffic is monitored and analyzed in two primary ways:
- DIR's full-time staff of security analysts monitor network traffic utilizing a suite of security tools to identify anomalous traffic.
- DIR utilizes a Security Information Management (SIM) system application to monitor the same suite of security tools.

What are Network Security Alerts?
DIR network security analysts provide timely and actionable alerts if any suspicious traffic is identified using our in-house monitoring tools or via an outside intelligence source. Network security alerts are sent to your Information Security Officer (ISO) and any other team members so designated by our ISO. If you would like additional staff to receive these alerts, please have your ISO or designee contact the
NSOC Help Desk.

How does the Network Security Monitoring occur?
A connection is made from your agency firewall/IPS device that allows security information (such as via syslog) to be sent to DIR, where a team of full-time security analysts monitor and analyze the information.
How do I receive Network Security Alerts?
DIR will notify you via email if any anomalous activity indicates your network is under attack or if you request assistance in analyzing or documenting security events.
Would DIR have to "punch" a hole into my network's primary defense in order to perform Network Security Monitoring?
No. The only connection made is from your firewall/IPS device(s), which allows DIR to monitor syslog information.
Does DIR look at client data during Network Security Monitoring?
No, DIR only examines the organization's external network during monitoring and does not look at client data. The client (the agency customer) is responsible for monitoring its internal network.
Does Network Security Monitoring consume much of my network's bandwidth?
Very little bandwidth is used during network security monitoring. You should notice very little change, if any, in the bandwidth being used.
