As more companies shift their IT infrastructure, data, and applications to the cloud, the need for reliable cloud security has become more acute. Fact is, the cloud has increasingly become a target for cyberattacks, as criminals follow the data from on-premises servers to cloud platforms.
This paper addresses the security of Sennheiser DECT Contact Center and Office (CC&O) headsets. It describes the DECT security chain comprised of “Pairing”, “Per Call Authentication” and “Encryption”, which are all part of the standard DECT protocol.
Change is the one constant in the IT world, and the way companies purchase and consume technology continues to transform and evolve. As customers continue to disrupt the IT value chain, a successful transition to cloud and hybrid models requires managed service providers (MSPs) to evolve their people, operations, and processes and employ advanced technology to secure their customers’ environments.
One of the biggest security takeaways from the first half of 2018 is that we can never make our computer systems perfectly secure, and the underlying hardware can be just as susceptible to exploitable flaws as the software that runs on it. Two new vulnerabilities—Meltdown and Spectre—affected nearly every device with a CPU, making this one perhaps the worst first half ever in terms of computer security. While not the most severe we’ve ever seen, these vulnerabilities hit the entire ecosystem of computers due to flaws in how modern processors isolate private memory
Networking refers to the range of hardware, software, processes, regulations, and protocols that make up computer and other networks. A network is a telecommunications system that allows connected devices to exchange data via cables or wirelessly (Wi-Fi). Networks provide shared access to systems, services, applications, and devices such as the World Wide Web, servers, printers, storage devices, email, messaging, and many more.
Security on networks is controlled by a network administrator through a set of provisions and policies that prevent unauthorized access to the network and network-accessible resources. Access to secured networks requires authentication usually via username and password (one-factor authentication), but can be augmented to include additional steps based on something a user 'has' such as generating a code via a security token, card, or mobile phone (two-factor authentication), and further augmented to include something a user 'is' such as a retinal or fingerprint scan. Firewalls enforce access policies on the network and anti-virus software or intrusion prevention systems (IPS) help to detect and inhibit malware and other potential threats.
Networks can be connected by electrical cable, radio waves, and optical fiber which are defined as layers 1 (physical layer) and 2 (data link layer) in the OSI model. Types of wired technologies include twisted pair wire, coaxial cable, ITU-T G.hn, and optical fiber. Wireless technologies include terrestrial microwave, satellite, cellular and PCS, radio and spread spectrum, and infrared. The basic hardware components of a network include network interface controllers (NIC), repeaters and hubs, network bridges, network switches, routers, and firewalls.
Ethernet is the most widely-adopted and used family of communications media used in local area networks (LAN), encompassing both wired and wireless network communications. IEEE 802 defines the standards and protocols that enable networked device communications. Networks can be classified by physical capacity or purpose such as personal area networks (PAN), local area network (LAN), storage area network (SAN), wide area network (WAN), virtual private network (VPN), and others.
