Shadow IT: Examples, Risks, and Mitigation Strategies

Introduction to Shadow IT

Shadow IT refers to the use of unauthorized hardware, software, or cloud services within an organization. While employees often turn to these tools to enhance productivity or bypass perceived bureaucratic hurdles, Shadow IT introduces significant security risks and operational challenges. Cybersecurity professionals must recognize and address these risks to protect their organizations effectively.

In this blog post, we’ll delve into Shadow IT by exploring its various forms, the associated risks, and how leveraging solutions like Microsoft Defender, Intune, and Purview can help manage and mitigate these threats. We’ll provide practical examples, discuss the implications for cybersecurity, and offer strategies to develop a comprehensive approach to Shadow IT.

What is Shadow IT?

Definition of Shadow IT

Shadow IT refers to the practice of employees using unapproved applications, devices, or cloud services without the knowledge or consent of the IT department. This phenomenon has grown significantly with the rise of cloud computing and the proliferation of SaaS (Software as a Service) applications. While these tools can enhance productivity, they operate outside the secure oversight of the IT department, creating blind spots in an organization’s security posture.

The Prevalence of Shadow IT in Organizations

The prevalence of Shadow IT is startling. According to Gartner, Shadow IT can account for 30% to 40% of IT spending in large enterprises. This indicates a significant portion of IT budgets is allocated to resources outside the official IT management purview​ (Quickbase & Workato Elite Service Partner)​​ (Gartner)​. Additionally, a 2023 survey by BetterCloud found that 59% of IT professionals struggle with SaaS sprawl, with 65% of SaaS applications being adopted without IT’s approval​ (Quickbase & Workato Elite Service Partner)​.

How Organizations Are Impacted by Shadow IT

1. Financial Services Sector: A large financial institution discovered that employees were using personal cloud storage services to share sensitive financial documents. This practice exposed the organization to potential data breaches and regulatory non-compliance, particularly concerning GDPR.
2. Healthcare Industry: A hospital system faced significant risks when doctors and nurses started using personal messaging apps to share patient information. This not only breached HIPAA regulations but also risked patient privacy.
3. Technology Companies: A tech startup found that developers were using unapproved open-source libraries and tools to speed up their development process. These tools, while useful, introduced vulnerabilities and inconsistencies that were outside the company’s control.

Shadow IT Examples

Common Forms of Shadow IT

Shadow IT can take many forms, each presenting unique challenges and risks. Let’s explore some shadow IT examples in detail:

Personal Cloud Storage:

1. • Overview: Employees use personal cloud storage services like Dropbox, Google Drive, and OneDrive to share and store work-related files. This often happens when official storage solutions are deemed too cumbersome or inaccessible.
   • Risks: These services can bypass corporate security measures, leading to potential data breaches and compliance issues. They also create challenges in tracking data access and usage.
   • Example: In a financial institution, employees using personal cloud storage to share sensitive financial documents can expose the company to regulatory non-compliance, particularly with GDPR and other data protection laws.

1. • Overview: Personal laptops, tablets, and USB drives are used to access and store company data. These devices often lack the security configurations mandated by corporate policies.
   • Risks: They can be vectors for malware and unauthorized access, especially if they are lost or stolen. Additionally, data stored on these devices is often not backed up or encrypted.
   • Example: Employees in a tech startup using personal laptops for development work can introduce inconsistencies and vulnerabilities that are outside the company’s control.

Shadow Networks:

1. • Overview: Employees set up unauthorized Wi-Fi networks or VPNs to access restricted websites or services, often to circumvent corporate internet restrictions or enhance connectivity.
   • Risks: These networks can bypass security controls, making it difficult for IT teams to monitor and secure the organization’s network. They can also be used by malicious actors to gain unauthorized access.
   • Example: In large enterprises, setting up rogue Wi-Fi access points to improve connectivity in certain office areas can create significant security blind spots.

Unsanctioned Development Tools:

1. • Overview: Developers use unapproved code repositories, libraries, or frameworks to expedite their work. This is often driven by the need for faster development cycles and access to the latest technologies.
   • Risks: These tools can introduce security vulnerabilities, legal issues (e.g., licensing compliance), and inconsistencies in the development environment.
   • Example: In a tech company, using unapproved open-source libraries can introduce security vulnerabilities and lead to potential intellectual property disputes.

Real Life Case Study

One example of how Shadow IT can affect an organization is the case of a public school system, which deployed Microsoft Defender for Endpoint and Microsoft Defender for cloud apps as part of a modernization of their infrastructure. The school system wanted to improve the security and performance of their devices and applications, as well as comply with the regulations of the Texas Education Agency.

By using Microsoft Defender for Endpoint, the school system was able to monitor and protect their endpoints from malware, ransomware, and other threats, as well as gain visibility into the health and compliance status of their devices. The school system also used Microsoft Defender for cloud apps to discover and assess the cloud applications used by their staff and students, as well as enforce policies and controls to prevent data leakage and unauthorized access.

One of the benefits of using Microsoft Defender for cloud apps was that the school system was able to identify a staff member who was playing games during working hours on their work PC. This was a form of Shadow IT, as the game was not part of the approved toolset and could pose a risk to the security and productivity of the organization.

Due to policy, the school system was unable to take any action against the employee directly, but they were able to tag the game as unsanctioned to block its use on the network. This way, the school system was able to reduce the impact of Shadow IT and ensure that their resources were used for educational purposes.
