Technology is essential to mitigate the risk of exposure to cyberattack. Note that mitigate means to reduce or lessen in severity, not preclude. It’s often difficult for IT service providers (ITSPs) to convince business owners that no one can guarantee complete elimination of cyberattack risk. Anyone with a computer connected to the internet is under attack. Your best option is preparation for the inevitable.
The last several years have seen a dramatic evolution in the sophistication of phishing attacks. While antiquated phishing tactics consisted of crudely constructed mass emails trying to snare as many victims as possible, today’s attacks are highly targeted, difficult to detect, and just as difficult to evade. Even more important, they’re pervasive.
The market is undeniably moving faster than ever. Driven by customer demand and enabled by innovative technology, the accelerating pace at which businesses are operating is exhilarating. At the heart of this is mobility. Wireless connectivity is delivering cost efficiencies and productivity increases while enabling enhanced customer experiences and insights. With the rapid expansion of the Internet of Things (IoT) and 5G on the horizon, the competitive advantages of mobility will only flourish more.
The Internet of Things is dramatically changing the market and opening up vast opportunities for solution providers to grow their businesses and expertise. IoT is no longer a concept of theory and proposition but a revolutionary wave of innovation driving real impact and opportunity.
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.
