Report: Using flow data to improve network security
Dartmouth College reduced threats to its network by 90 percent and cut back incident analysis process time to mere minutes from weeks by using flow data. This is just one use case described in a report from Lancope called "The State of NetFlow: Advancing Security and Performance through Network Visibility."
As networks become increasingly complex with expanded mobility options and the consumerization of IT, flow data can give IT departments better visibility and control in a cost-effective way, according to the report. Lancope spells out best practices for using flow data and enumerates some of the benefits, including:
- More comprehensive, in-depth monitoring and protection
- Faster, more streamlined troubleshooting
- Vast savings of time, cost and resources
- Protection from APTs and other internal & external threats
- Support for forensic investigations
- Better compliance with industry regulations
- Visibility into next-generation architecture including 10G, MPLS, IPv6 and virtualized networks
Other organizations discussed in the report include the Puget Sound Blood Center, which has been able to reduce downtime, saving $22,680 for each hour it used to lose, and the Grafisch Lyceum Rotterdam, which is enjoying a 75 percent cost savings on hardware, software and maintenance for internal monitoring.
