Word of the Day: Daily updates on the latest technology terms

Word of the Day Daily updates on the latest technology terms | June 29, 2020 deperimeterization In network security, deperimeterization is a strategy for protecting a company's data by using encryption and authentication at the data-level. In the past, most security efforts were focused on protecting company data at the perimeter of the network. With the advent of ubiquitous connectivity and a mobile workforce, however, network administrators began to question whether the traditional border model of IT security was practical or cost-effective. According to a survey from Netrounds, a network monitoring software provider, monetary damage from unplanned drops in network quality averages about $600,000 per organization. These costs can be avoided (or at least reduced) with the help of effective network management best practices that go beyond perimeter defense. The concept of deperimeterization was recognized early on by Paul Simmonds of the Jericho Forum, a non-profit group dedicated to "the development of open standards to enable secure, boundaryless information flows across organizations." As early as 2004, Simmonds foresaw that a hardened perimeter security strategy would be impossible to sustain and was fundamentally at odds with an agile business model. Today, the concept of deperimeterization is closely aligned with the zero trust model. Continue reading about deperimeterization...
