Today’s companies operate in a complex security environment. On the one hand, the threat landscape is growing. Bad actors are becoming more and more refined as they get access to new tools (like AI) and offerings (like hacking-as-a-service). On the other hand, companies are dealing with more sensitive data than ever before. This has prompted consumers and regulators alike to demand for better security practices.

To top it all off, companies are operating in an increasingly decentralized digital model. Gone are the days of firewalls. Employees want to be able to access work from anywhere, and on their own networks and devices. This has heightened the prevalence of insider threats, making it much easier for employees to inadvertently (or intentionally) share corporate data with others.

One way that insider threats have become particularly problematic is through social media. In this article, we’re taking a closer look at how social media can compromise data security for organizations — and what they can do to address this concern.

The challenge with social media

Depending on the platform, social media encourages users to share information about their life and experiences in varying degrees. When it comes to employees, social media can easily be a channel to discuss work-related topics, whether that’s sharing excitement about an upcoming product feature, posting a photo of a company event, or even sharing sensitive information with a colleague via private chat features. This degree of sharing — both of personal and corporate information — can pose a number of challenges for businesses.

For starters, there’s a risk of accidentally sharing information. An employee could post a picture of their desk on Instagram to show off their lunch for the day or the view from their office and forget to blur the sensitive information on their computer screen. Alternatively, a software developer might seek out peers on a Reddit forum to try and solve a particular issue with their code, and inadvertently share proprietary code when asking for help.

Some social media channels also allow for a certain degree of anonymity. A disgruntled employee could take to Twitter or Reddit and make corporate secrets widely available to competitors or regulators.

On the other side of the equation, cybercriminals use social media platforms as resources for their attacks. These bad actors understand that people are prone to sharing information, so they access public profiles to try and glean useful information that can then be used for sophisticated social engineering attacks. In addition, they can use the likes of LinkedIn to map out an organizational structure, get access to corporate email addresses, and even identify when core individuals are on vacation. They can also review an individual’s follower or contact list, create a fake account for someone at the company that’s not on the list, and encourage the employee to share sensitive information.

All of these challenges can put a business at risk of sophisticated threats including phishing and other forms of social engineering, brand impersonation aimed at tricking customers, data theft, and even large-scale data breaches. Despite the potential impact of a social media leak, it’s notoriously difficult for companies to control the egress of data through these platforms. That said, below are some of the things companies can proactively do to mitigate these threats.

Staying ahead of social media threats

Businesses can’t dictate what their employees say on their personal social media accounts — that’s a given. That said, they can educate their users on the dangers of disclosing too much information and the best ways to protect their data, credentials, and corporate details. This can be done through onboarding training, gamified security weeks where employees are given challenges to identify and act out security best practices, as well as lunch and learns dedicated to security.

For companies that provide their employees with mobile devices, there’s also an opportunity to set clear expectations around what can be posted from a corporate device or not. They can also encourage individuals to change their phone passwords often, and to use a password manager for their social accounts.

There are also services and technologies that can help here. For example, companies can hire social media scanning services to identify fraudulent accounts and flag them to employees. In addition, a comprehensive data loss prevention tool can also be instrumental in identifying when sensitive data has been exposed and kickstarting an immediate response.

Evolving with the times

When it comes to maintaining robust security measures, companies have a responsibility to keep up with cultural shifts and the adoption of new platforms. Security practitioners need to be continually aware of any new threat vectors, incorporating new measures and policies as needed and keeping up with best practices. This is why having a robust, comprehensive, and iterative cybersecurity strategy — one that accounts for both insider and external threats — is more important than ever.
