Zero Trust is a security notion that demands users to be verified, authorized, and to frequently validate security configurations before being conferred entry to applications and data. Some pros and cons associated with zero-trust models, as they relate to network visibility and monitoring providers, have been provided below.
PROS OF ZERO-TRUST MODELS
- Zero trust models reduce time to breach detection and gain visibility into enterprise traffic. The concept succeeds in the policy of ‘trust but verify’ as opposed to ‘always verify and never trust.’ It offers security experts visibility into the exact individual accessing the network, the location, type of application, and the time. Security administrators and systems can observe the internal and external actions of all users, devices, and data.
- It reduces the complexity of the security stack. It is very complex and costly to implement security with legacy technologies, and that is why zero trust models make the process less expensive and complicated.
- Zero trust models also help in solving the security skills shortage. “The evolving cybercrime landscape is stretching security experts to the limit.”
- It decreases scope and the cost of compliance. Zero trust networks are essentially divided into parts, hence lessening the reach of laws and compliance audits.
- Zero trust models facilitate the move to the cloud. Cloud-based zero trust solutions serve a new safety criterion specifically devised to secure applications in the cloud and data center.
CONS OF ZERO-TRUST MODELS
- Technical debt is one of the cons associated with zero trust models. Multiple systems and architectures “have not taken into account the least privilege or PAM, and to retrofit such a model would be a significant project.”
- Legacy system challenge. Zero trust models require multiple levels of authorization as it demands all participants to get verified for access.
- Numerous systems utilize peer-to-peer models, such as windows operating systems and wireless mesh networks. “P2P breaks the zero-trust model as systems communicate in a decentralized manner, which breaks the micro-segmentation model.”
- The zero trust segmentation model also gets affected when public and private cloud services work together and unite to offer a service that is not unique.
- Moving from silos to data-centric is also a challenge. A large number of systems are silos of data, including both delicate and less sensitive data, which would need to experience segmentation based on the data.
