Is Network Security Slowing you Down?
Measuring the Latency impact Created by Next Gen Security Solutions
As an IT professional, you are well aware of the challenges posed by network latency. Applications like audio and video delivery, bandwidth sensitive mobile applications, cloud computing and storage services are extremely sensitive to network latency.
What you may not realize, however, is the amount of latency created by your Next Generation Intrusion Prevention Systems (NG-IPS) and Next Generation Firewalls (NG-FW). While they are critical to protecting your network, these security tools and others that perform deep packet inspection can increase latency, significantly impacting your overall application performance.
Recently we worked with a large health care services provider trying to figure out why it was taking so long to send MRI data between locations. This was causing significant frustration for patients, doctors and medical staff. Having been aware of Aukua’s nanosecond precision capture and analysis tools, they asked for our help. The company suspected one of more of their NG-IPS devices was causing the delays, but they did not have a way to confirm this. Since these security tools do not treat all packets the same, they were unable to detect or measure the application latency issue with artificial traffic such as ICMP. And since some applications were being adversely delayed and others were not, they could not rely on the NG-IPS vendor’s generic latency specs for various packet sizes. In addition, compliance rules prohibited them from introducing new traffic into their live network.
