In the present day and age, the use of cloud powered solutions is rapidly on the rise. The flexibility that is inherently available within cloud solutions also poses a threat vector in the form of un-authorized access.
So, a great security solution to this threat comes in the form of Zero Trust Security. This model entails that each end user that accesses the cloud infrastructure will first be authenticated. Further, this policy will apply across the board and at every instance.
The zero trust model revolves around a primary concept that no end user is above the laid down security policies of an enterprise. Now, how to go about zero trust. Well, it starts with removing all access related privileges.
Secondly, you can further enhance the efficacy of this model by micro segmenting your network on the basis of parameters such as job roles or functional areas. This will create an additional tier of security within the cloud network of an enterprise.
Lastly, the way to implement zero trust is to add a dynamic layer of user authentication, in addition to the static layer that is generally user passwords. This dynamic tier should be based on extremely personal, unique and constantly changing parameters.
Examples of such dynamic attributes can be the user’s fingerprint, a time barred One Time Password (OTP) or any similar parameter. Access to the cloud infrastructure will be awarded only upon successful authentication of both layers of security.
In today’s hostile cyber environment, which has been further complicated by the remote work scenario, zero trust seems to be the only viable security policy. Enterprises need to adopt a proactive approach in implementing this policy, before its too late.
