Security used to be easy. Anything within a network could be trusted. However, in the era of cloud platforms, telework, and shared systems, it is hard to assume that such an approach is valid. Organisations operate amid various dangers that can be exploited to gain unauthorised access. Usually, companies recognise the necessity of using security measures only after encountering some sort of problem. If this situation describes you, you are not alone. In the era of digitalisation, securing a company’s data has become harder than ever.
If you were wondering why conventional measures no longer work, we will explain how Zero Trust Security revolutionises the way businesses protect their systems and data.
What is Zero Trust Security?
Zero Trust Security operates on one principle. Never trust by default but always verify.
Every access request is checked in order to verify the user’s identity, device state, location, and behaviour patterns. As a result, access is provided only if it is really necessary.
Such an approach minimises risks related to unauthorised access and potential hazards.
Why Old School Security Models Do Not Work Anymore?
Conventional security models were aimed at providing protection to the outer boundary of a network. Users were given broad access once they entered it.
Nevertheless, the modern environment makes it hard to set the boundary and determine users who operate inside the organisation’s network.
As a result, attackers have a chance to use any compromised account in order to infiltrate across systems. In this regard, Zero Trust prevents such situations by limiting access each time.
How Zero Trust Security Works?
Unlike certain products, Zero Trust Security is not about the application. It is about using various security practices in combination.
Main elements of such security model include managing users’ identity, multi-factor authentication, and least-privilege access. The user gets minimum access that he or she needs to fulfil his or her duties.
Moreover, the status of devices is checked and abnormal behaviour is detected in order to minimise risks and identify potential threats.
Advantages of Zero Trust Security Model
First of all, Zero Trust reduces risks significantly. Attackers are restricted and cannot access other parts of the network even if one part is compromised.
Furthermore, visibility is improved since organisations get information about who accessed what and why. As a result, it becomes easier to comply with requirements.
How to Adopt Zero Trust Security Model?
The process of adopting the Zero Trust Security Model does not involve any major changes in systems. Organisations should focus on gradual improvement of existing security architecture.
In this regard, it is possible to start with reinforcing identity verification, setting up multi-factor authentication and restricting users’ access permissions.
Conclusion
Zero Trust Security provides a solution to protect systems in the era of digitalisation by verifying each access request and minimising unnecessary access permissions.
For companies that need to create a reliable and strong security framework, The Node IT provides consulting services and assistance in adopting Zero Trust Security strategies.
