Zero Trust Security had become the most efficient model of security strategy in IT network security. Zero Trust Security is an IT security model that carries the slogan “Never trust, always verify”, which in elaboration, it is a model that request for strict identity verification to every individual and device attempting to access resources on a private network, either within or outside the network parameters. Additionally, Zero Trust Security is based on number of principles for it to deliver efficient cybersecurity strategy. What are the Zero Trust Security principles for successful cybersecurity strategy?
Zero Trust Security principles include:
1. Multi-factor Authentication (MFA)
Multi-factor authentication (MFA) is the core essence of Zero Trust security. With Zero Security being based on the concept of viewing every access attempt as a threat, MFA requires users to input code from different devices. This implementation can be seen in certain online shopping platform or social media platform where in order to access the platform, in addition to the password, specific code is send to another device and need to be entered as well as a way to verify the true identity of the user.
2. Microsegmentation
Zero Trust security applies Microsegmentation. Microsegmentation in Zero Trust security increases security as it involves the practice of dividing the security perimeters into small zones. Simply put, microsegmentation breaks the network into parts where authentication are needed in order to access any particular part of the network. Additionally, with microsegmentation, lateral movement (a condition where attacker moves in the network after gaining access) can be contained as they are unable to moves to another segment without authorisation.
3. Least-privilege access
Least-privilege access of Zero Trust security only allows access when necessary. With this principle, the number of users or devices having access to the network can be minimised thus reduces the exposure of the sensitive parts of the network to unauthorised users.
4. Continuous monitoring and authentication
One of the most important Zero Trust Security philosophy is that always assume that cyber attack may occur from both within and outside of the network. Hence, it is crucial for continuous monitoring and authentication to ensure users and devices are continuously verified thus identifies malicious activities in the network.
