2. Customer Problem Discovering Shadow IT
2/16/2019 8:16 AM
Customer Problem
People use potentially risky cloud applications without IT approval or knowledge.
Discovering Shadow IT
IT has limited visibility into how these apps are used.
When a user makes use of a cloud application without notifying or getting approval from their IT department, this is a problem for the IT personnel. This is one example of what we mean when we talk about the end of the perimeter; users being able to use any application they want and most IT departments will never know about it.
The IT folks need to know who is using which applications, and wants to make sure that their users only use secure applications.
Two examples: One, is users installing and using Slack as an instant messaging solution for work related collaboration. This is something that is happening in many organizations, and Cloud App Security can easily identify it. The other example is large file transfer, where people are trying to move large files and start using a cloud storage or file transfer application they choose themselves. Most CISOs and IT professionals understand this scenario. What makes people use a risky application instead of the enterprise-approved application is not that they are evil or want to harm the organization, they find an application that solves their business need easily, and use it. Most, though, are not aware that this exposes their organization to a range of threats.
Assessing the risk of cloud applications requires special knowledge and research. Definitely a challenge for the IT team.

3. Sample Use Case Discovering Shadow IT
IT admin discovers significant cloud app usage, including a risky storage app.
The admin tags the cloud apps as unsanctioned, then generates a blocking script for Blue Coat firewall.
Discovering Shadow IT
Let’s step through this use case to see how Cloud App Security helps organizations discover risky cloud storage applications in their environments.
We are starting after Cloud App Discovery is deployed, you have successfully uploaded the relevant logs, and log data is flowing into the portal.

4. Implementing with Cloud App Security
2/16/2019 8:16 AM
Implementing with Cloud App Security 1
Use the Cloud Discovery dashboard to see current cloud app usage. 2
List the specific cloud storage apps in use, rank them by risk, and review the details of that risk score. 3
List the users who use the identified app. 4
Tag the identified app as unsanctioned so it can be monitored.
For this use case, we will use the Cloud Discovery dashboard to see current cloud app usage. Then we will identify the cloud storage apps in use, rank them by level of risk, and view detailed information to understand why that risk level was assigned. For a risky storage app, we will identify who is using it, mark the app as unsanctioned, and then block the app at the firewall by exporting a configuration script for a Blue Coat firewall appliance.
Then we will review usage by user including which apps are in use, amount of data transferred, and the IP addresses used. 5
Block the app at the firewall by generating a script to import into Blue Coat. 6
Review usage by user including which apps, amount of data transferred, and which IP addresses were used.

This filters the Discovered apps list to show only cloud storage applications and we can sort these by Risk Score to easily see which apps you should focus on first.
MEGA, for example, has a risk score of 4. This score tells us an app is risky, but does not tell us why.
