Consider the data flow “octopus,” as shown in Figure 8.1. How can the analysis system gather data from all these sources that, presumably, are protected themselves?

Introduction

As an analyst, I often find myself wondering how to gather data from various sources that are protected by a firewall. In this post, I’ll show you how to use SQL Server and Azure SQL Database together as a proxy for your data sources, allowing you to connect to them securely and then direct all access through the analysis system.

Data from the data sources can be streamed to the analysis system.

Data from the data sources can be streamed to the analysis system. This is a good way to get data from a variety of sources, as well as make it available in real time or near real time.

Streaming can be done over a network (i.e., via an open internet connection) or over local connections between devices such as USB sticks or wireless networks.

The analysis system can use an API to gather data from each of the various sources.

An API is a set of routines, protocols, and tools for building software applications. It’s also a standardized way to communicate between systems. For example, you might use an API to gather data from one system and send it to another.

This kind of communication would be useful in our case because we want the analysis system itself (the “octopus”) to be able to collect data from all these sources that presumably are protected themselves—that is, each source has its own security mechanisms in place that prevent unauthorized accesses or changes from occurring within their boundaries.

The analysis system can serve as a proxy for the various data sources, getting information that each source provides and then relaying it to all other components.

The analysis system can serve as a proxy for the various data sources, getting information that each source provides and then relaying it to all other components. The analysis system gathers data from multiple sources and then relays it to all other components. As shown in Figure 8.1, it allows you to aggregate data from different sources into a single repository where you can access it more easily than if each source were required to provide its own information directly.

For privilege escalation to occur, a user must be able to gain access to a data source that they would not normally have access to.

To gain access to the data source, a user must be able to gain access to a resource that they would not normally have access to. The data source must also be protected in such a way that it is inaccessible by normal users.

For privilege escalation to occur, a user must be able to gain access to a resource they would not normally have access too. They can do this by compromising or manipulating another system or process with similar characteristics (e.g., running as root on Linux).

Conclusion

The octopus, as described in this chapter, is a great example of how data flow analysis can be used to protect sensitive data from privilege escalation. By using an API, the analysis system can gather information from all of its components that are protected by physical security measures, such as firewalls and authentication systems. This allows the analysis system to act as a proxy for these sources and collect information about them before relaying it on down to other components (such as databases) that need access to that data. Allowing only authorized access is a common way of protecting sensitive information within organizations because it not only prevents outsider hackers from getting into your network but also helps limit any damage they might cause by gaining access through an authorized user account (that’s good news if you’re using Windows or Mac OSX).
