Data layer security describes the inspection of data packets to detect attempts to compromise network applications. In this context, data layer security and application layer security are synonymous.

Delivery networking describes a system of computers networked together across the Internet that cooperate transparently to deliver content (commonly referred to as a Content Delivery Network). Requests for content are intelligently directed to nodes that are optimized for performance to ensure that applications are readily available. Also see Application Delivery Networking.

Denial of service (DoS) usually refers to an attack that attempts to make a computer resource unavailable to its intended users by flooding a network or server with requests and data. It can also simply refer to a resource, such as e-mail or a Web site, that is not functioning as usual. Often, the denial […]

A Diameter Edge Agent provides the extra security service providers require to connect securely with third-party partners when needed and share resources, such as in roaming and billing use cases. It does this by enabling Diameter signaling messages to flow smoothly among networks while also adequately disguising the topology of both networks.

Diameter interfaces provide connections among Diameter nodes to enable essential service provider network functions such as authentication, online and offline billing, and policy and charging.

Caching is the local storage of network data for re-use, to cut down on transfer time for future requests. With Web pages, static caching simply serves objects — typically images, JavaScript, stylesheets — as long as they haven’t passed their expiration date. But static caching can generally only be used for about 30 percent of […]

A content delivery network (CDN) is an infrastructure that helps organizations deliver static Web content, rich digital media, and everything in between, to employees, vendors, partners, and customers worldwide, in the fastest amount of time at the lowest possible cost.

CIFS (common Internet file system) is a protocol that lets programs make requests for files and services on remote computers across the Internet. Developed by Microsoft®, CIFS is a public or open variation of the older SMB protocol. It uses the client/server programming model.

Clientless remote access is remote network access obtained without the installation of software on a user’s device.

One of the oldest and most common type of DDoS attack, a connection flood, is also known as a “TCP connection flood” since it attempts to occupy all possible TCP connections on a server. By flooding the server with requests for new connections, it prevents legitimate requests from being established and served.
