5 tips for using a CASB to safely enable social media in your business

Tools and Tips

From Facebook’s 1.65 billion monthly active users to Twitter’s rise as a mainstream broadcast media outlet, social media continues to experience rapid and wide adoption from users around the globe. For the enterprise, social media presents both opportunities and challenges. The opportunity is primarily centered around leveraging social to make your employees more collaborative and productive at their job, not to mention the many benefits to the business. If you aren’t interacting with your customers via social media, there is a good chance that your competitors are.

Even with all the upside, there are a number of challenges that are impacting the adoption of social media in the enterprise. First, social media promotes transparency and some businesses are not ready to change their culture overnight. The other challenge is the risk associated with sensitive data leaking via social media. What if someone posts or shares something they are not supposed to? What would be the impact to our company if intellectual property was leaked, customer data exposed, or out-of-compliance activities took place? Compliance is a real issue whether it is FINRA compliance for financial firms, PCI for retail, or protected health information (PHI) that is connected to HIPAA compliance. Social media makes it very easy to share anything and that anything could be cause for concern depending on the scope of your business.

The question is, do you embrace social media in your place of business and reap all the benefits or do you block social media altogether? This is the catch-22 as you ultimately need to make the decision between using social or being safe. What if you could enable the use of social media in your business, but do it safely? I want to share with you how a cloud access security broker (CASB) such as Netskope can let you have your cake and eat it too. Here are 5 tips.

Tip #1 Use a scalpel, not a sledgehammer

Your first inclination might be to just outright block social media by using your perimeter security device. Instead, use a CASB that can identify and block risky activities taking place in real-time. A risky activity could be someone from the hospital staff posting PHI to a social media app of their choice. Focusing on the risky activity instead of being forced to block the app outright means that everyone can use the app safely.

Tip #2 Implement a category-level policy

There are the mainstream social media apps like Facebook, Twitter, LinkedIn, and Snapchat and then there are the dozens or potentially hundreds of social media apps that could be in use by users. In fact, a recent Netskope Cloud Report found that an enterprise has 23 social media apps in use on average. Make sure that your CASB supports a category-level policy that can administered to cover all social media apps. The last thing you want to do is create and manage dozens of policies individually.

Tip #3 Don’t be blind. Cover all ways social is being used

There are two primary ways that users interact with social media apps. First is the browser from their Mac to PC and the other way is from an app on their iOS or Android device. Make sure that your CASB can inspect social media usage involving both browsers and mobile apps. If you can’t cover mobile apps then you are leaving yourself vulnerable.

Tip #4 Incorporate advanced DLP into your policy

This is tied to the scalpel approach covered in tip #1. The key here is that you need to be able to inspect not only attachments and text that is part of a social media post or share, but you need to do it in a smart way so you don’t end up with a ton of false positives and end of blocking everything. The example I like to use is a financial services company that wanted to safely enable social media, but at the same time be FINRA compliant. This involved looking for keywords such as “guarantee” or “recommend” combined with public company names and stock symbols. This requires that your CASB have an advanced cloud DLP solution with AND/OR rules, custom keyword dictionaries, proximity, and other key features. You can learn more about this use case by watching this demo video.

Tip #5 Coach users

The final tip is focused on end user experience and behavior modification. A successful enterprise social media strategy involves training users to use their best judgement. This traditionally involves training classes, email reminders, and even getting users to sign agreements. You can take this a step further by using a CASB to implement real-time coaching and have custom messages pop up when the user performs an out-of-compliant action. When they attempt to do something risky, warn them in real-time and coach them to do the right thing.
