THANK YOU FOR SUBSCRIBING
Zero trust security strategy, a model that promises to draw a line in the sand of high profile data contraventions caused by threat actors who bypass perimeter-focused security protection.
FREMONT, CA: Joe Biden’s signing of an Executive Order calling for federal agencies to execute a zero-trust architecture by 2024 makes it evident that this security proposition is the new standard to strive for. Here are the five key principles of zero-trust security:
1. Verify before Trust
Verification before trusting must be followed religiously and this is what zero trust security stands for. The increasing cyber-attacks have revealed the breach of default trust given to traffic, users and devices once they are inside a network. It becomes an easy catch for spiteful actors to log in and exfiltrate sensitive information. Zero trust is capable of alleviating such possibilities by considering all network traffic as untrustworthy.
2. Data-centric security
There is an urgent need to protect data as data breaches continue to be an issue every passing day. The existing approaches are not enough in protecting business assets. Hence, a proper re-evaluation of data security points towards the zero trust model.
3. Authentication must be vigorous
Verification of authenticity is a basic principle of maintaining security. Authentication must be done at every step when a user tries to access files, applications or cloud storage services. In the present day work culture, using IP addresses, usernames and passwords are time-consuming, and no longer convenient, especially in IT firms. Zero trust security comes out as the best possible way of authentication in the present day.
4. Least Privilege Strategy
The least privilege strategy plays a vital role in zero-trust security as it limits the user device access permission to only that’s essentially necessary. Least privilege access diminishes the attack probabilities, limits lateral movement and lessens the chances of spiteful actors getting to your company’s most sensitive data.
5. Monitoring and Logging
Logging and monitoring appear to be the critical precepts of the zero trust model. It implies logging and monitoring that is happening on the network. Regular supervision helps to identify and remediate threats much earlier before the attack.
