Juniper Networks is betting that device-fingerprinting is a better way of dealing identifying and repulsing security attacks compared to the traditional method of blocking based on Internet protocol (IP) addresses.

The company has updated it line of Web applications protection, anti-DDoS (distributed denial of services) attack and the SRX Series Services Gateways products identify attacks using the device-device fingerprinting method, which according to Juniper is more accurate.

Upon detection of an attack, the Juniper tools will collect data about the attacking device in order to fingerprint it and block the attack at that instant and in the future. The captured information about the device will also be passed along to other Juniper equipment via Junos Spotlight Seucre, a cloud service which Juniper customer can subscribe to.

-Junos DDoS Secure for automated protection against DDoS attacks of up to 40 Gbps and low-and-slow application attacks
