Endpoint security or endpoint protection is an approach to the protection of computer networks that are remotely bridged to client devices. The connection of laptops, tablets, mobile phones and other wireless devices to corporate networks creates attack paths for security threats. Endpoint security attempts to ensure that such devices follow a definite level of compliance to standard.
A computer network is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections (data links) between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi.
Network computer devices that originate, route and terminate the data are called network nodes. Nodes are generally identified by network addresses, and can include hosts such as personal computers, phones, and servers, as well as networking hardware such as routers and switches. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols. This formidable collection of information technology requires skilled network management to keep it all running reliably.
Endpoint security management is a software approach which helps to identify and manage the users’ computers access over a corporate network. This allows the network administrator to restrict certain website access to specific users in order to maintain and comply with the organization’s policies and standards. The components involved in aligning the endpoint security management systems include a virtual private network (VPN) client, an operating system and an updated antivirus software. Computer devices that are not in compliance with the organization’s policy are provisioned with limited access, to a virtual LAN.
A virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). LAN is the abbreviation for local area network and in this context virtual refers to a physical object recreated and altered by additional logic. VLANs work by applying tags to network frames and handling these tags in networking systems – creating the appearance and functionality of network traffic that is physically on a single network but acts as if it is split between separate networks. In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed.
Endpoint security systems operate on a client–server model with the security program controlled by a centrally managed host server pinned with a client program which is installed on all the network drives. There is yet another model called the software-as-a-service (SaaS), the security programs and the host server are maintained remotely by the merchant. In the payment card industry, the contribution from both the delivery models is that the server program verifies and authenticates the user login credentials and performs a device scan to check if it complies with a designated corporate security standards prior to permit network access.
Corporate security identifies and effectively mitigates or manages, at an early stage, any developments that may threaten the resilience and continued survival of a corporation. It is a corporate function that oversees and manages the close coordination of all functions within the company that are concerned with security, continuity and safety.
