Digital technology is booming in the post-pandemic world. However, with the growing use of technology, the threat landscape is evolving simultaneously. Traditional security measures are no longer sufficient to keep critical data safe from cyber threats.
In today’s time when workplaces are changing and with the increasing use of cloud computing, mobile apps, etc, organisations need a paradigm shift in their security measures to cope with the evolving threats. Zero-trust is the perfect answer to all the security needs of your organisation.
As the name suggests, Zero-trust means trusting no one and verifying everyone irrespective of their source. Earlier, organisations relied on on-premise resources like firewalls and VPNs (Virtual Private Networks) to protect their network access assuming that everything within the network was safe.
However, with cloud computing and other technological innovations, such a security model was not feasible. Instead, a comprehensive and holistic approach was needed to identify the threats and eliminate them. The zero-trust security solution assumes that no user, device or connection can be trusted until and unless properly verified.
Zero-trust assumes that threats can come from both inside and outside the network. It operates on the principle of “never trust, always verify”. Every user, connection or device, whether inside or outside the network, must authenticate before being granted access. With this strict policy, the zero-trust model provides security not just to a single network but also helps secure remote access, personal devices and third-party apps.
Zero-trust is not a product or service but is a security architecture following a set of security guidelines.
MICROSOFT ZERO TRUSTThe zero-trust model is based on three core principles. These three principles can be applied across your digital estate, namely devices, apps, IT infrastructure, data and network. The core principles of the zero-trust model are:
As stated previously, the thrust of the zero-trust model is extended across the digital estate. The zero-trust model is applied in the following functional areas of the business to serve as an integrated security infrastructure:
Verifying and authenticating identity before granting access. Identities can include anything from human to non-human entities to users, computers or IoT devices.
Ensuring devices that access your network are secure and compliant so that risks can be minimized significantly.
Using telemetry to detect attacks and anomalies and automatically blocking and flagging for risky behaviour.
Moving towards data-driven protection measures to keep data safe even in case of access outside the organisation network. Classifying, encrypting and restricting access to data based on organisational policies.
Applying appropriate controls and technology to discover shadow IT, ensuring appropriate in-app permission and monitoring user access for enhanced protection against threats.
Segmenting the network into small isolated compartments so that lateral entry to other compartments can be minimised. Also encrypting the internal communications and continuously monitoring for real-time threat detection.
● All the functional areas, namely Apps, Data, Infrastructure, Devices, Networks, and Identities are represented.
● Each functional area is integrated and protected through security policy enforcement and optimization.
● Threat protection unifies all the signals across the organisation in real-time thus enhancing threat visibility and streamlining the incident response tracking for better coordination.
Modern IT environments need modern solutions. With multiple devices and users accessing data, both inside and outside the network, traditional security approaches are not enough to plug the loopholes.
With a zero-trust security solution, the primary benefit is that it limits the area of attack. This is done by segmenting the threat in a particular area, which minimizes its impact. Also, the zero-trust model supports modern work environments like distributed teams or hybrid or remote workplaces thus making it a flexible and scalable solution for the organisations.
Most importantly, the zero-trust approach verifies every access request, protecting precious data from falling into the wrong hands. It reduces the risks posed by vulnerable devices and implements multiple authentication factions that otherwise are bypassed in traditional perimeter-oriented security protections.
With the immense benefit of the zero-trust model, it is rapidly gaining popularity. However, implementing it may be a tricky affair without proper expertise.
