What is Shadow IT?

Any IT technology that workers use without the approval of the IT security department is called Shadow IT.

The largest organizations today are using, on average, 976 SaaS applications. These are all apps that IT security is aware of and controls. Here’s another stat. 80% of employees admit to using SaaS applications at work without securing approval from the IT department.

What are the key drivers of Shadow IT growth?

Rapid cloud adoption

93% of enterprises are embracing hybrid cloud environments or migrating completely to the cloud within the next 5 years. Already nearly 40% of enterprises operate entirely on SaaS.

While organizations were hesitant to trust cloud platforms 8-10 years ago, that perception has largely changed. Most organizations have come to trust cloud environments and what they offer. Cloud service providers have matured, and the platforms have grown and expanded to include many robust applications.
In addition, business-critical applications on-premises might require purchasing a new server and network infrastructure, configuring the architecture, and deploying the applications in the data center, which might take weeks or months. With cloud SaaS applications, deploying new mission-critical applications for the entire organization takes only a few clicks.

This tremendous shift to cloud SaaS and the ease with which businesses can install third-party cloud SaaS applications has led to the explosion of cloud SaaS apps in the enterprise. However, despite the many advantages that come from this paradigm shift to cloud SaaS, it also opens organizations to a myriad of cybersecurity threats, one of which is Shadow IT

Lack of knowledge about security risks

There are two main reasons why employees do not understand the risks of Shadow IT. First and foremost, the company doesn’t conduct regular cybersecurity awareness trainings.

Second, 80% of global population have the optimism bias. This percentage is consistent across race, nationality, gender, and age. Optimism bias makes people believe that they are invincible. Bad things like ransomware attacks or sensitive data leak happen daily but not with them. Danger is far and they are beyond its reach. Until they aren’t.

Chase for comfort

58% of employees aren’t completely satisfied with their company’s technologies – and bend the rules to accommodate.

With the tremendous number of cloud Software-as-a-Service (SaaS) applications available to organizations today, businesses have access to an infinite number of capabilities in the cloud. In addition, if there is a feature or function in the cloud that does not exist natively, there is a third-party app that can add it to a company’s cloud SaaS environment.

Hybrid work models and BYOD

In the US, 87% of employees prefer the flexibility of the remote/hybrid setup. Though having many benefits, this model of work undermines corporate IT security. Employees no longer work in safe networks. As a result, the enterprise has little to no control over the applications they use.

The same is true for BYOD practice. Meanwhile, over 80% of enterprises encourage employees to use their personal devices for work.

What are the main risks of Shadow IT?

In this section, we’re discussing the main shadow IT risks and discuss how they impact your business.

Data breach

The key danger of allowing unmanaged apps to get installed in your cloud SaaS environment is that it opens your organization up to the possibility of malicious applications. Attackers realize that most businesses today are storing large quantities of their production data in cloud environments. Using phishing attacks coupled with OAuth abuse, an attacker can masquerade a malicious app as a legitimate application and entice an unsuspecting end-user into granting access (OAuth token) to a malicious application.

OAuth tokens granted to a third-party cloud application allow the application to access the cloud SaaS environment without a password. By its very nature, OAuth is a token-based authorization mechanism that, when used properly, is a secure, cloud-native authorization protocol. However, its weakest link is the end-user. Unless a user scrutinizes the permissions requested by an application, they may be granting high levels of access to an unknown application and third party.

Data loss and Leak

Shadow IT operations can lead to specific data getting leaked unintentionally or exposed to third parties that should not have access to the data. The fallout from leaked data can be tremendous, leading to fines, damaged business reputation, legal action, and financial repercussions that can last for years. Some businesses may never fully recover from a data leak incident.

Cloud SaaS applications may include storage services not sanctioned by IT that end-users may use to store work data. Essentially, this is data exfiltration from the sanctioned cloud environment and can lead to data leaks.

Additionally,  certain cloud apps may not protect data in-flight and at rest with proper encryption, increasing the likelihood of an attacker being able to compromise business-critical data.

Lack of visibility and control

One of key problems of Shadow IT is that it’s invisible for IT security teams. This makes the control of risky applications impossible. Shadow IT creates substantial security gaps that hackers exploit to attack companies.

More than 40% of file-sharing traffic was routed to unsanctioned apps and services. And 34% of IT teams say the lack of visibility into SaaS security settings is one of the leading causes of SaaS misconfigurations.

Non-compliance

Even if a third-party application is not malicious in nature and is a legitimate tool or extension of the cloud SaaS environment, it may go against compliance requirements or other data access restrictions. Due to specific compliance regulations, organizations may need to expressly limit who or what applications have access to certain data types. When users begin installing third-party applications that have not had a proper risk analysis performed, it can lead to compliance violations.

IT overspending

Up to 50% of IT spending is estimated to go to Shadow IT in large organizations. In many cases, these applications duplicate the functionality of the available and approved solutions. As a result, companies can spend substantial budget on similar applications many of which pose serious danger to their data integrity.

Overcoming Shadow IT: 4 Strategies

1. Regular employee training

As mentioned earlier, many employees engage in Shadow IT operations without even knowing it. They may simply be trying to accomplish day-to-day tasks as efficiently as possible, and installing a third-party cloud SaaS app may seem like the best approach.

Employee cybersecurity training, including training around what constitutes shadow IT operations and how users can avoid using unsanctioned apps, can go a long way in helping to curb their use. Most users want to meet the expectations of the business and align with corporate policies regarding the use of technology and other resources.

Good communication with users from both the business and technology side can help users understand the impact of Shadow IT and how they can avoid becoming involved in using unsanctioned technologies that can compromise business-critical data. In addition, ensure employees have an opportunity to review this information periodically to have the most up-to-date information on corporate technology policies.

2. Providing sanctioned tools

If employees are restricted from using unsanctioned third-party cloud SaaS apps, make sure they have an approved app that allows them to be equally productive. The first step to providing what end-users need is understanding their cloud technology needs. Asking the right questions helps to understand the needs and the proper steps forward:

• What functionality and capabilities do they need to carry out business-critical tasks?
• Is the functionality already included natively in the cloud SaaS environment?
• Have the proper risk assessments been performed on the apps requested? What compliance requirements apply?

Users who feel the business is doing their best to understand their needs and facilitate those with sanctioned applications that align with compliance and governance requirements will be more likely to work in harmony with these requirements.

3. Inventory of cloud SaaS apps

Shadow IT is a tremendous problem in the enterprise because businesses often lack the visibility needed to know which apps are installed and used. Additionally, legacy monitoring and security tools cannot provide the visibility and insights needed in cloud SaaS environments as organizations move to the cloud.

Companies need modern cloud-native cybersecurity tools to understand cloud SaaS application usage, which employees are using them, and which data the apps are accessing. Without visibility and understanding of this aspect of technology usage in your cloud SaaS organization, it will undoubtedly lead to Shadow IT.

Apart from inventory, it’s also important to carry out continuous Shadow IT Monitoring. It will help you detect the applications that users add without the knowledge of IT security team.

4. Enforcing policies for cloud SaaS apps

In addition to employee training, providing sanctioned tools, and having visibility to cloud SaaS apps used in the cloud SaaS environment, businesses must have the technology tools to enforce governance of cloud SaaS apps and their usage. Without the right policies in place, there can still be users who inadvertently use unsanctioned third-party apps. It also helps enforce corporate boundaries for unscrupulous users who may knowingly attempt to use unsanctioned apps.

In addition, many compliance frameworks require appropriate policies and governance guardrails in place to have the correct cybersecurity posture dealing with in-scope or sensitive data. Technology policies help complete the various layers of compliance and security for cloud SaaS environments.

How to Make Shadow IT applications visible

Many organizations may have small or limited IT teams wearing many “hats” of responsibility. Even larger organizations with a security operations center (SOC) can be taxed to perform risk analyses on the thousands of apps available in cloud SaaS marketplaces. In addition to performing risk analyses on cloud SaaS apps, knowing employee behaviors, what they are installing, and which apps they are granting access to would be next to impossible to control using only manual means.

By leveraging next-generation artificial intelligence (AI) and machine learning (ML), organizations can have the technology tools needed to help provide visibility and automated actions required in today’s cloud environments. In addition, AI/ML tools help monitor cloud SaaS environments, detecting anomalies and risks that may be undetected by using manual, human-driven processes.
