There is a growing increase in interest on zero trust during the COVID-19 pandemic as several companies have accepted that their perimeter based security method creates vulnerabilities, especially when it comes to a remote workforce. In the past few years, applications were pushed into the cloud, however, users suddenly being placed outside the perimeter is a brand new challenge for several IT and cybersecurity teams.
Among these latest obstacles, threats are becoming much more complicated than before with their methods. Along with the others, your company might be moving towards to a zero trust security approach to assist in improving security positions and decreasing the risk to your organization. Based on your business resources, goals, as well as legacy systems, you might come across various barriers and advantages while executing a zero trust security approach.
What are the zero trust principles?
- Assume that all networks cannot be trusted. You need to verify every request that comes.
- Apply the least privilege access, as long as they can carry out the task required.
- Assume a data breach. You can reduce the risk by checking and monitoring everything.
What are the barriers to zero trust?
The implementation of a zero trust architecture needs you to unwind the legacy infrastructure, workflows, as well as processes that make new difficulties. Based on the size and the complexity of your company, you may come across barriers like:
- Resource limitations
- Time investments
- Cohesive and complete execution
- Change with the vendors
- Board level support
- Team buy-in
- Funding and budget
What are the benefits of zero trust?
- Streamline the operating expenses
- Lower overall capital expenditure
- Permit adaptability using digital transformation
- Improved compliance reporting
- Mitigate breaches and prevent threats
- Boost control in the cloud setting
- Enhance the visibility of the network traffic
How to build a zero trust security model?
Setting up a zero trust architecture is a complicated journey is a process that is continual. Each company’s journey to zero trust security model could appear differently and it is important to be very patient and to prioritize your initiatives and projects one step at a time. From small to big firms, you should expect the overall procedure will not be a sprint but a marathon.
MA zero trust security model needs an end to end approach that is based on various elements such as:
- Data – classifying confidential data to guide regulations and controls on what must be protected.
- People – regularly monitor the access of users and to apply the least privileged ideas at each level.
- Workloads – create a cloud governance process as well as management solution, check workload configuration, and perform inventory.
- Devices – apply the network segmentation concepts to set up microperimeters that will isolate the IoT devices.
- Networks – decrease the attack surface as well as the lateral movement through the segmentation of boundaries surrounding your network assets.
- Visibility and analytics – investing in the abilities to correlate events in disparate domains.
- Automation as well as orchestration – add response processes and technologies that could put threats first, enhance the workflow, and cut back on the mean time to respond.
