What are the principles of zero trust security and how can it secure small businesses in New Jersey
Traditional cybersecurity measures are no longer an ideal option for the security of business organizations. A flexible architecture focusing on users, devices, and services is imperative. The concept of zero trust security was developed by considering these considerations.
Principles Of Zero Trust Security
- Zero trust security structure was designed to take on the present and future IT security threats. It is built to trust no person, device, or service, whether inside or outside the corporate network. The five zero-trust principles allow organizations to take full advantage of this security model.
The following principles of zero trust security ensure the successful adoption of this security model into IT strategy.
Analyze Protect Surface
- Identification of the attack surface is one of the foremost principles of the zero-trust security model. In addition to users, devices, data, and services, the protection surface must also include network pathways. Management domains and end-points extending beyond the corporate LAN can be revealed by a protect surface analysis.
Network traffic that extends across geographically dispersed LANs cannot be handled by traditional cybersecurity technologies working within LAN. On the other hand, the protective surface of zero trust architectures extends far beyond the protection of a corporate LAN. This is what makes zero-trust architectures more popular among organizations.
Analyze The Existing Cybersecurity Controls
- After mapping the protection surface, the following principle of zero trust security focuses on the evaluation of the existing cybersecurity tools in the organization. When implementing a zero-trust security model, the existing tools can be utilized without investing in newer technologies.
Many of the existing toolsets of the organization are likely to be helpful in these instances. However, these tools may be deployed in the wrong location. Therefore, it is essential to analyze ways to extend the capabilities of existing cybersecurity controls. This helps IT and security teams redeploy the existing tools to reach the expanded areas, including cloud data centers and remote locations.
Incorporate Modern Tooling And Architecture
- In most cases, existing cybersecurity tools may not be able to justify an end-to-end zero-trust architecture model. Additional tools will need to be procured to add extra layers of protection where security gaps are identified during zero-trust implementation. Fortunately, modern security tools can pick up the slack that traditional tools fail to reach.
These tools have built-in support for Zero Trust Security model architecture, and they support Zero Trust techniques like Single Sign-On, Multi-Factor Authentication, etc. Additionally, advanced threat protection tools can be used to identify emerging threats. They enable the implementation of security policies precisely where needed.
Apply Zero Trust Policy
- Once all the principles of zero-trust security are followed, and the necessary tools are in place, the zero-trust policy security framework can be readily implemented. Based on a strict set of standards, zero trust policies are rules that allow access to various resources when absolutely necessary.
These policies should clearly describe access levels, permissions, resources, user accounts, etc. Once these high-level policies are implemented, the security devices that adhere to the allow list can be configured while denying everything else.
Conduct Monitoring And Management
- When a zero-trust architecture has been implemented, the final step is to conduct necessary monitoring and management. Even a modern security structure like zero trust architecture can be exploited by hackers if there are deficiencies in the implementation. Therefore, it is crucial to regularly monitor, measure, improve, and adapt these security policies.
