Your employees may pose the greatest cybersecurity threat to your business, not only due to their tendency to click on phishing emails or reuse passwords but also because they are using applications that your IT department is unaware of.
This phenomenon is known as Shadow IT, and it represents one of the fastest-growing security risks for organizations today. Employees often download and utilize unauthorized applications, software, and cloud services—typically with good intentions—but they inadvertently create significant security vulnerabilities.
What Is Shadow IT?
Shadow IT encompasses any technology utilized within a business that has not been approved, vetted, or secured by the IT department. This can include:
- Employees utilizing personal Google Drive or Dropbox accounts for storing and sharing work documents.
- Teams signing up for unapproved project management tools like Trello, Asana, or Slack without IT oversight.
- Workers installing messaging applications like WhatsApp or Telegram on company devices for communication outside official channels.
- Marketing teams employing AI content generators or automation tools without verifying their security.
Why Is Shadow IT So Dangerous?
The lack of visibility and control over these tools means IT teams cannot secure them, exposing businesses to various threats.
- Unsecured Data Sharing: Employees using personal cloud storage, email accounts, or messaging apps may inadvertently leak sensitive company information, making it easier for cybercriminals to intercept.
- No Security Updates: IT departments regularly update approved software to patch vulnerabilities, but unauthorized applications often go unchecked, leaving systems vulnerable to hackers.
- Compliance Violations: If your business is subject to regulations like HIPAA, GDPR, or PCI-DSS, using unapproved applications can lead to noncompliance, fines, and legal issues.
- Increased Phishing and Malware Risks: Employees may unknowingly download malicious applications that seem legitimate but contain malware or ransomware.
- Account Hijacking: Utilizing unauthorized tools without multifactor authentication (MFA) can expose employee credentials, allowing hackers to access company systems.
Why Do Employees Use Shadow IT?
In most cases, the use of Shadow IT is not malicious. For instance, the "Vapor" app scandal revealed a significant ad fraud scheme where over 300 malicious applications were found on the Google Play Store, collectively downloaded more than 60 million times. These apps masqueraded as utilities and lifestyle tools but were designed to display intrusive ads and, in some cases, phish for user credentials and credit card information. Once installed, they hid their icons and inundated users with full-screen ads, rendering devices nearly unusable. This incident illustrates how unauthorized applications can easily infiltrate devices and compromise security.
Employees may also resort to unauthorized apps for several reasons:
- They find company-approved tools frustrating or outdated.
- They seek to work faster and more efficiently.
- They are unaware of the associated security risks.
- They believe that obtaining IT approval takes too long and opt for shortcuts.
Unfortunately, these shortcuts can result in significant costs for your business in the event of a data breach.
How To Stop Shadow IT Before It Hurts Your Business
Addressing Shadow IT requires a proactive approach since you cannot manage what you cannot see. Here are steps to get started:
1. Create An Approved Software List: Collaborate with your IT team to develop a list of trusted, secure applications for employee use. Ensure this list is regularly updated with new, approved tools.
2. Restrict Unauthorized App Downloads: Implement device policies that prevent employees from installing unapproved software on company devices. Employees should request IT approval for any necessary tools.
3. Educate Employees About The Risks: It is crucial for employees to understand that Shadow IT is not merely a productivity shortcut but a security risk. Regular training should be provided on the dangers of unauthorized applications.
4. Monitor Network Traffic For Unapproved Apps: IT teams should utilize network-monitoring tools to detect unauthorized software use and identify potential security threats before they escalate.
5. Implement Strong Endpoint Security: Deploy endpoint detection and response (EDR) solutions to monitor software usage, prevent unauthorized access, and detect any suspicious activity in real time.
Don't Let Shadow IT Become A Security Nightmare
The most effective way to combat Shadow IT is to address it proactively before it results in a data breach or compliance failure.
