A massive increase in the number of employees working remotely, a growing number of ecosystem partners, and the adoption of public cloud, has reignited the need for a zero trust model.<\/p>\n
Close to 80% of organisations have a zero trust strategy today.<\/p>\n
This is because every user, device, and application are now connected over an external network \u2014 the Internet.<\/p>\n
To protect their business, IT leaders must ensure that, prior to enabling access to critical business resources, all traffic is inspected, each entity is validated based on identity and policy, and that applications are obfuscated from the open internet.<\/p>\n
This is where zero trust network access becomes vital to the business.<\/p>\n
Zero trust network access (ZTNA) is a strategy that embraces least-privilege secure access, which is the notion that users and applications should never inherently be trusted, and should only have access to the specific resources they need, and nothing else.<\/p>\n
Instead of allowing for remote network connections through technologies like VPN or VDI, or allowing in-office users to go directly to business resources simply because they are on the corporate network, trust is only granted once traffic is inspected, the entity is properly validated, and policy is met.<\/p>\n
Connections are then established only through outbound connections from the app to the zero trust service.<\/p>\n
API integrations between technologies like zero trust network access (ZTNA), identity, endpoint security and SIEM ensures that policies are automatically updated based on context.<\/p>\n
A zero trust security model should:<\/p>\n
Created in April 2019 by Gartner, the term Zero Trust Network Access (ZTNA) represents a set of new technologies designed for secure access to private applications.<\/p>\n
Also referred to as Software-defined perimeter (SDP), ZTNA technologies use granular access policies to connect authorised users to specific applications, without the need for access to the corporate network, establish least-privileged app-level segmentation as a replacement for network segmentation, and without exposing the applications location to the public internet, unlike a VPN concentrator.<\/p>\n
Unlike VPNs or firewalls. ZTNA services are designed to securely connect specific entities to each other, without the need for network access.<\/p>\n
In most cases these are employees and third-party users connecting from home, on the road, or in the office.<\/p>\n
ZTNA is not limited to just users, it\u2019s important to understand that ZTNA can also apply to application-to-application traffic as well in the form of microsegmentation.<\/p>\n
Some key concepts about ZTNA include:<\/p>\n
Andre Kannemeyer, CTO at Duxbury Networking says: \u201cWe see a lot of customers with security concerns associated with digital business enablement, remote work, and cloud transition. As PaaS, SaaS, and IaaS use increases, there is more data outside of the data centre, more users are working remotely, and VPNs are typically sluggish and exploitable. Using outdated network topologies, it is impossible to protect all of this.<\/p>\n
Benefits provided by a ZTNA include:<\/p>\n
\u201cZTNA has been one of the buzzwords floating around for the last couple of years, and a lot of our clients have considered it. We see a large adoption rate in the large enterprise space and expect the same adoption rate to grow in the small and medium business markets,\u201d says Kannemeyer.<\/p>\n
