Network Security Monitoring Tool

In order to be truly effective, a network security monitoring tool should have complete visibility over all network activity and all devices connected to the network. With anything less than complete visibility, you are seeing only part of the picture and possibly allowing threats to go undetected. You will never know until after the event.

Some tools to monitor network security lack the necessary mechanisms to provide complete visibility. Flow-based tools, for example, provide statistical data about the flow of network traffic, but do not let you drill down into the data to see what is contained within network packets. They also fail to provide meaningful data about applications using non-standard network ports.

Agent-based tools to monitor network security also have their failings. If, for example, you manage a large network, the maintenance overhead of installing and maintaining agents on each device is substantial. An agent-based network security monitoring tool is also an inappropriate solution for organizations with BYOD policies or that provide public access to a wireless network. Administrators cannot install agents on users´ personal devices and therefore these devices are not monitored.

Tools to Monitor Network Security with Deep Packet Inspection

In order to achieve complete visibility over all network and all devices connected to the network, a network security monitoring tool should be capable of deep packet inspection and content-based application recognition. Tools to monitor network security with deep packet inspection capture metadata from network packets and analyze their contents to see what payloads they contain.

The process is similar to a postal worker opening every letter to read its content – rather than counting letters, seeing where they have come from, and looking at their destination as flow-based tools do. With this deep level of visibility, tools to monitor network security perform a continuous network security health check – quickly detecting intrusions and threats from both outside and within the organization.

Tools to monitor network security with deep packet inspection provide further benefits in addition to elevating network security to the highest level. Administrators can monitor network performance and troubleshoot network issues. They can analyze bandwidth and resource consumption to identify high areas of demand and redundant resources. They can also monitor user activity and web activity – including http activity from a CDN network – to ensure acceptable use policies are being adhered to.

The Benefits of an Agent-Free Network Security Monitoring Tool

The two primary benefits of an agent-free network security monitoring tool are a low maintenance overhead and visibility over all devices connected to the network. These are achieved due to the way in which a network security monitory tool connects to the network via the core switch and sends the captured metadata to a central management portal via a SPAN or mirror port.

Details of all network and user activity is displayed on the central management portal in context. Administrators can drill down into the data to conduct forensic analysis in the minutest detail. Administrators can also configure the network security monitoring tool to send them security alerts if anomalies or suspicious activities are detected within network packets.

For organizations operating a WAN over multiple locations, sensors can be deployed on the remote platforms. Metadata is captured by the sensors in each of the remote locations and sent back to the central management portal for analysis and reporting. This provides administrators with complete WAN visibility over all network activity and all devices connected to the network with the same depth of details as if the network packets had travelled through the local network.
