The major strategic goal of cyber security in the digital age is to combat and mitigate data breaches. A company's data is its most valuable asset to protect. This blog post will explain to you the components of a Zero Trust Model.
Zero Trust Model is a cybersecurity model which maintains strict access control for any user or device. It works by verifying and authorising every connection they make.
The Zero Trust model is based on the principle "never trust, always verify". No distinction is made between outside and inside. It is also known as Zero Trust Architecture, or just as a ZTA.
This model is different from traditional ideas. It takes an equal approach to all devices, services, and users. It also assumes that they cannot be trusted. This is a significant change, known as a paradigm shift.
The Zero-Trust model for more effective security is based on the following pillars
Zero Trust Networks
The ability to segment, isolate, and control the network remains an important success factor for Zero Trust Model. It must be ensured that only certain units (users, applications or devices) with specific requirements may access sensitive network segments or micro perimeters.
Zero Trust Workloads
The workload is a generic term that refers to the entire application stack, which is the sum of all applications. In the broadest sense, it is about monitoring applications and their controlled execution across the enterprise network and in the cloud. As with any other area of zero trust, these connections, applications, and components must be treated as a potential attack vector and equipped with zero-trust control mechanisms and technologies.
Zero Trust Devices
IoT and network-based device technologies have created enormous potential for network and enterprise endangerment. Security professionals must take steps to implement a zero-trust strategy. This requires the ability to isolate, secure and control every device and computer on the network at all times.
Zero Trust Data
One of the pillars of a zero-trust strategy is data security. The key components of this approach are for example: securing and managing data, categorising and developing data classification schemes.
Zero Trust People
Companies must also consider the user in the zero trust strategy so that they do not become the gateway to attacks. Most companies today do not know how much power and trust they give users. The authority of any strategy is to restrict user access. This includes securing login and protecting users while interacting with the company network.
This includes all the technologies required to authenticate users (e.g. multi-factor authentication) and continuous monitoring and controlling of their access and permissions.
“Users, employees, business partners and even customers often do not know what role their actions play in a holistic security strategy.“
Visibility and Analytics
Visibility is the key factor in defending valuable assets of the business, e.g. data, knowledge, or corporate secrets. But you cannot protect the invisible and you cannot fight a threat that you do not see or understand.
Zero Trust Model requires security teams to maintain visibility and control over their entire digital business environment, regardless of location, device, user count, or hosting model.
Tools such as security information management (SIM) systems or advanced security analytics platforms, security user behavioural analytics (SUBA) and other analytic systems, provide visibility into user activity on the network and the endpoints.
Automation and Orchestration
A zero trust platform uses technologies that enable automation and orchestration.
Analytics demonstrate the value of automation and orchestration tools and technologies for businesses and security teams. These tools and technologies enable companies and security teams to streamline their operations across the enterprise. It must be possible for leading providers of these platforms to be able to integrate into other systems to use complementary security information or pass on useful data. Conversely, companies must be able to automate their business processes.
