TLS and SSL are the standard protocols used for securing stream-based TCP Internet traffic. DTLS is a protocol based on TLS that is capable of securing the datagram transport. DTLS is well-suited for securing applications and services that are delay-sensitive (and hence use datagram transport), tunneling applications such as VPNs, and applications that tend to […]

DNS servers provide the roadmap to the Internet, and help clients find the servers they are looking for. A DNS query flood uses a network of clients to target a single server with floods of valid requests.

The roadmap to every single computer on the Internet is held in DNS servers. The DNS NXDOMAIN flood attack attempts to make servers disappear from the Internet by making it impossible for clients to access the roadmap.

The DMZ, or demilitarized zone, is a portion of an enterprise network that sits behind a firewall but outside of or segmented from the internal network. The DMZ typically hosts public services, such as Web, mail, and domain servers. Application delivery controllers usually sit in the DMZ, providing application access to the public servers.

A disaster recovery plan covers the data, hardware, and software critical for a business to restart operations in the event of a natural or human-caused disaster, including power failures, computer viruses, legal issues, and worker strikes. It should also include plans for coping with the unexpected or sudden loss of key personnel. The analysis phase […]

A Diameter Routing Agent (DRA) is a functional element in a 3G or 4G (such as LTE) network that provides real-time routing capabilities to ensure that messages are routed among the correct elements in a network. The DRA was introduced by the 3GPP to address the increased Diameter signaling traffic and growing complexity of 4G LTE networks.

A Diameter load balancer distributes signaling traffic across multiple servers in a network. This load balancing capability is essential for service providers (SPs) to achieve high scalability and availability.

Data integrity refers to the need to ensure that data remains valid and accurate, with alterations only through authorized processes. A wide variety of factors can impact data integrity, from security to breaches to hardware failures, causing sensitive data to be lost or compromised. Protecting enterprise data assets across dozens of applications and hundreds of […]
