The traditional security approach of building walls and erecting barriers is no longer enough to protect businesses from the ever-evolving threat landscape. In today's world, businesses must adopt a Zero Trust security model to protect their data and systems from constantly evolving cyber threats.
What is Zero Trust Security?
Zero Trust is a security paradigm that assumes that all users, devices, and applications are untrusted and must be verified before being granted access to corporate data and systems. This approach contrasts with the traditional security model, which relies on perimeter defenses to keep threats out, but gave users and devices broad trust and permissions once inside.
The Zero Trust security model has been gaining popularity in recent years as businesses have become more aware of the shortcomings of the traditional, perimeter-based security approach. Once someone is through the perimeter in the old paradigm, they can do whatever they want.
Zero Trust removes the reliance on perimeter defenses by verifying, authenticating, and authorizing all users, devices, and applications before allowing them access to corporate data and systems.
What Does Zero Trust Replace?
The traditional perimeter-based security model is no longer effective in today's world of constantly evolving cyber threats. The Zero Trust model replaces the perimeter-based security approach with a more holistic and comprehensive approach that considers the changing nature of cyber threats.
Zero Trust vs. Least Privilege
Zero Trust and Least Privilege are two security models that share some similarities but have some critical differences. Both models assume that all users, devices, and applications are untrusted and must be verified before granting corporate data and systems access. However, the Zero Trust model goes further than Least Privilege by requiring that all users and devices be authenticated. In a Least Privilege security approach, each user has the least privilege they need to do their job (and nothing else), whereas a Zero Trust model verifies every interaction.
The Advantages of Zero Trust
There are many advantages to adopting a Zero Trust security model, including:
- Increased Security. Businesses can greatly reduce the risk of data breaches and other security incidents by verifying, authenticating, and authorizing all users, devices, and applications before allowing them access to corporate data and systems.
- Reduced Costs.The Zero Trust security model can help businesses reduce their overall security costs by eliminating the need for costly perimeter defenses.
- Improved Efficiency. The Zero Trust security model can help businesses improve their overall security efficiency by reducing the number of false positives and negatives.
- Greater Flexibility. The Zero Trust security model is more flexible than the traditional perimeter-based security model and can be adapted to changing business needs.
- Improved Visibility. The Zero Trust security model gives businesses greater visibility into their overall security posture and allows them to identify and mitigate potential threats easily.
- Greater User and Device Trust. The Zero Trust security model builds trust between users and devices by verifying, authenticating, and authorizing all users and devices before allowing them access to corporate data and systems.
- Improved Compliance. The Zero Trust security model can help businesses improve their compliance with industry regulations and standards.
- Increased ResilienceThe Zero Trust security model can help businesses improve their overall security resilience by reducing the impact of security incidents.
- Improved User Experience. The Zero Trust security model can provide users with a better experience by simplifying and streamlining the process of accessing corporate data and systems.
- Better Data ProtectionThe Zero Trust security model can help businesses better protect their data by encrypting all data in transit and at rest.
Some Drawbacks of Zero Trust Cybersecurity
There are some potential disadvantages to adopting a Zero Trust security model. But rather than true disadvantages, many of these can be seen instead as challenges to be overcome in the process of achieving much better security.
- Increased Complexity. The Zero Trust security model can be more complex than the traditional perimeter-based security model and may require businesses to invest in additional security tools and technologies.
- Limited Support. Vendors and service providers may have limited support for the Zero Trust security model, though this is likely to change as Zero Trust becomes more widely used.
- Implementation Challenges. There may be challenges associated with implementing a Zero Trust security model, such as identifying and authenticating all users and devices.
- Potential Performance Issues. The Zero Trust security model may cause potential performance issues if not implemented properly.
- Lower Security Levels. The Zero Trust security model may result in lower security levels for some users and devices if they are not properly authenticated and authorized, which can impair their ability to do their jobs.
But note that while there are challenges, these challenges do not outweigh the significant advantages of Zero Trust cybersecurity. This simply acknowledges the fact that it can be challenging to transition to Zero Trust cybersecurity. The transition doesn't occur overnight.
Moving Toward Zero Trust Cybersecurity
While there is no silver bullet for implementing Zero Trust cybersecurity, there are several steps that businesses can take to move toward this model.
- Implement Identity and Access Management. The first step is implementing an identity and access management (IAM) solution that can authenticate and authorize all users and devices.
- Enforce Least Privilege. The second step is to enforce the principle of least privilege, which requires that users only have the permissions they need to perform their job tasks.
- Implement Multifactor Authentication. The third step is to implement multifactor authentication (MFA), which requires users to provide multiple forms of authentication, such as a password and a security code.
- Encrypt Data by Default. The fourth step is to encrypt all data in transit and at rest.
- Implement Security Monitoring. The fifth step is implementing security monitoring tools and technologies to help identify and mitigate potential threats.
Of course, some platforms will do all this for you. Zero Trust is both a type of technology and a general business philosophy, frequently requiring consulting or audits to engage with. But once you've established Zero Trust network security, maintaining and operating the system should be simpler, rather than more complex.
