In today's world, data is spread across an infinite number of services, devices applications, and people. Zero trust is a Network and Security model that requires identity verification for every person and device trying to access resources on a private network. As well as, it is one of the emerging trends in security. It requires organizations that do not trust anything inside or outside in network infrastructure. Instead, it should be auditing, monitoring, and tracking on every aspect of IT infrastructure. The three elements in Zero Trust security such as verify every user, validate every device and intelligently limit access. Zero trust is data centric, so network access is granted to packets, not to people, devices or locations. It requires three ingredients such as next generation firewalls, network orchestration solutions and virtual network infrastructure. One of the main benefits of zero trust is adaptability of any environment.
This model of information security basically kicks to the curb the old castle and moat mentality that had organizations focus on perimeter while assuming everything already and therefore it is cleared for access. It approach relies on existing technologies and governance process to accomplish its mission of securing an enterprise IT environment.
To mitigate gaps in security and the vulnerabilities they create, multilayered approach to security is vital for prevention, detection and response. In simple words, protect your data and trust no one. It has solutions include
Data loss prevention
Encryption
Validation and ID Prevention
Centric Tagging
Information Centric Security
Centric Analytics
Threats come from everywhere that the attackers use more sophisticated technology such as hiding in encrypted traffic to evade detection. The technology such as security analytics, encrypted traffics management, endpoint detection and response etc.
