Understanding Application Security

Web-based applications are changing the dynamics of security. Previously, specific applications were associated with specific protocols and ports, making policy enforcement at the host level relatively straightforward. Web applications that can be accessed from anywhere create challenge for network administrators to effectively manage traffic flows and access to data while delivering the security and network services.

An individual can connect to the network using multiple devices simultaneously, making it impractical to identify a user, an application, or a device by a group of statically allocated IP addresses and port numbers.

Applications such as instant messaging, peer-to-peer file sharing, Webmail, social networking, and IP voice/video collaboration evade security mechanisms by changing communications ports and protocols, or by tunneling within other commonly used services (for example, HTTP or HTTPS). Organizations need control over the applications and traffic on their networks to protect their assets against attacks and manage bandwidth.

Juniper Networks’ AppSecure is a suite of application-aware security services for the Juniper Networks’ SRX Series Firewalls and NFX Series devices to deliver security services to provide visibility and control over the types of applications traversing in the networks. AppSecure uses a sophisticated classification engine to accurately identify applications regardless of port or protocol, including nested applications that reside within trusted network services.

AppSecure works with additional content security through integrated Content Security , intrusion prevention systems (IPS), and Juniper Networks Juniper Advanced Threat Prevention Cloud (ATP Cloud) on the security devices for deeper protection against malware, spam, phishing, and application exploits.
