ARE ZERO TRUST NETWORKS THE FUTURE ENTERPRISE SECURITY ARCHITECTURE MODELS?
Traditional network security models rely on the assumption that a device or an asset is safe once it is on a "trusted" internal network. As today's workforce becomes more cloud-centric and mobile, data is consistently being accessed outside these closed internal networks and as a result, new security gaps and vulnerability to breaches arise.
A zero trust network (ZTN) is an access model that assumes everything is on the open internet and operates under the principle of "trust no one, verify everything". In a ZTN, all user requests are fully authenticated, authorized, and encrypted in real-time.
- In addition to using a password to identify a user, secondary and tertiary factors are used further validation.
- In addition to trusting a user's device because it is on a network, verify that the device itself is healthy and compliant.
- Rather than allowing or denying full access, grant specific access to services, applications, or data required.
The core strategy of a ZTN is to continuously monitor the network for suspicious activity. Network permissions are controlled through intelligent and dynamic parameters to meet the needs a mobile workforce. Microsoft provides a friendly user guide on how to implement a ZTN strategy.
HOW CFOS ARE NAVIGATING THE FINANCIAL IMPACT OF COVID-19

- Focus aimed at initial financial impact: Capital resources and liquidity are among the top concerns as businesses deal with a sharp drop in economic activity, as well as the lasting effect on recovery.
- Recovery times lengthen: Acknowledging the outbreak will not dissipate quickly as only 20% of businesses expect to return to business as usual in one months time,
- Clampdowns on costs continue: Reduction in discretionary spending and processes put in place to tighten approvals.
- Stimulus impact is assessed: Nearly half (49%) of finance leaders have announced their company plans to take advantage of the assistance provided by government relief plans.
