In the first part of this blog series, I took a look at how an understanding of digital strategy and digital risk is key to starting a security transformation journey. And in the second, I dug further into how a secure access service edge (SASE) architecture with security service edge (SSE) capabilities and zero trust principles can help mitigate the types of digital risk. In this final part, I will outline a few key use cases to show all of these elements in action:
Creating continuous adaptive trust
An analyst in an organization needs to access various publically avaiable market data websites and SaaS applications. They will use this information to enrich internal data which will then be used to drive decision making.
But, some of these sites and apps have been identified as risky. Rather than blocking access to these sites and apps, SSE capabilities can be used to safely allow the analyst to access the data. Here’s how:
- Threat protection helps identify and neutralize incoming threats
- Remote browser isolation (RBI) can direct the analyst to the sites via RBI and reduce the risk.
- Data loss prevention (DLP) policies allow access as there is no sensitive data being used in this process
- Action Awareness allows the analyst to only download in this process.
As a result, the analyst is not blocked or prevented from accessing the information and services they need, nor, have they been granted access without relevant controls creating excessive risk for the organization.
The analyst can now perform their work, access the data they need, and their role is enabled to create value for the organization, supporting business growth, by the very nature of the business process and function they can safely perform.
Enabling secure collaboration between organizations
Consider two investment bankers from two different banks who are working on a deal and need to share documents. Both organizations use O365 and SharePoint as the standard platform for sharing data with third-parties, with Bank 2 holding the primary records on their SharePoint.
Banker A, from Bank 1, needs to access Bank 2’s SharePoint to collaborate on the documents with Banker B from Bank 2.
Here’s how leveraging SSE capabilities can safely enable this access:
- Threat protection helps identify and neutralize incoming threats (e.g. any malware in documents)
- Instance Awareness allows Banker A to access the O365 instances of both Bank 1 and Bank 2 only, while blocking all other instances of O365.
- Action Awareness allows Banker A to perform only the actions that they need to in order to perform their work. Actions not needed, for example, download, delete, or share, can be restricted, enforcing the principle of least privilege.
This way, Banker A is not blocked from Bank 2’s instance of O365 nor have they been granted an exception that opens up access to all instances of O365 which would result in creating excessive risk for Bank 1.
As a result, value is created for the organization by enabling the normal course of business and risk is managed within appetite allowing the organization to deliver on its strategic agenda.
