Although Zero Trust service in the Philippines is becoming a standard in today’s security landscape, many organizations are still working out how to incorporate it to their existing IT infrastructure. This need is further amplified when they have to accelerate their adoption of working anywhere. It has overwhelmed many organizations with different security risks to solve and tremendous pressure to keep the business secure.
Users can also compound the security risks your IT team face on a daily basis. Giving them the opportunity to use any device enables them to work flexibly, but lessens visibility for your IT team. There is also no guarantee that they are always following best practices to keep their devices safe. This is where we come in. We work closely with your company so you can safely integrate a successful Zero Trust Service. We do this by applying our service framework found below.
Zero Trust Service Framework
Defining the protect surfaces (Customer’s expectation and Best Practices)
The threat landscape is always evolving, it is hard to determine where attacks will come from as attack surfaces are always expanding. However, you can determine what surface to protect within your system, such as important data and applications. CT Link works with your IT team to find what you need to protect as our first step and give you inputs based on industry best practices.
Map the flow of data
Once your protect surface has been defined, we will need to learn how your data move within your network. This contextual insight will help us better protect your data without hindering your user’s experience while they work. CT Link will work closely with your IT to ensure that we correctly map the flow of data and how it interacts within the network so that the measures used in Zero Trust is always for the protection of your data rather than hindering business operations.
Designing the Zero Trust Network
To increase the security of the protection surface, micro-perimeters will be placed around the defined critical areas so that a more granular security can be used. This is done by integrating a segmentation gateway (SWG) or a next-generation firewall (NGFW) into the design. By requiring users to go through software-defined barriers to verify their identities you decrease the likelihood of a breach. This is known as “microsegmentation”.
Creating the Zero Trust Policies
Policies are then created based on the level of protection your team defines for the protection surface. These are enforced through the integrated SWG or NGFW.
These policies are based on these key questions:
- Who should be accessing a resource?
- What application is being used to access a resource inside the protect surface?
- When is the resource being accessed?
These are important in zero trust because you need to doubt all access and allow only those who fit each criteria while also limiting their access to ensure no outsider can access your network with no restriction.
Monitor and maintain the network
CT Link’s Zero Trust service doesn’t end once the architecture has been built, we also monitor the network alongside your team to ensure that the solution is running smoothly. We keep all events and actions documented for further analysis whenever you need it. This is to maintain the standard of Zero Trust Security that you expect.
