7 Security Risks of BYOD and How to Avoid Them


The allure of Bring Your Own Device (BYOD) policies is undeniable. They promise cost savings, employee satisfaction, and increased productivity.

However, beneath this veneer of convenience lies a complex web of BYOD risks, including data breaches and social engineering attacks. According to Verizon’s Data Breach Investigations Report, 74% of breaches are caused by human elements, such as errors and misuse of devices.

“Ignoring the BYOD security risks is like leaving your house doors unlocked in a storm and hoping for the best,” notes Julio, Vice President of Operations for Tenecom.

“If your business is going to allow people to use their personal devices for work, you need to ensure you follow best practices for BYOD security to ensure that your company data is never at risk.”

In this article, we’ll take a closer look at some of the BYOD risks, and what you can do to avoid becoming the next victim of a data breach.

Understanding BYOD: More Than Just a Trend

BYOD has evolved from a trend to a standard practice in many workplaces. It involves employees using their personal devices, such as smartphones, tablets, and laptops, for work purposes.

Research from Statistics Canada indicates that just over two-thirds, or 66.4%, of Canadian enterprises have at least one employee using their personal mobile device for work purposes.

This shift has been driven by the increasing ubiquity of personal technology and the demand for workplace flexibility. However, the diversity of devices and operating systems can pose significant challenges to maintaining consistent security measures and ensuring compatibility with corporate networks.


The 7 Security Risks of BYOD: A Closer Look

BYOD introduces several security risks. The most prominent is the increased likelihood of a data breach. Personal devices often lack the robust security measures of company-issued hardware, making them more vulnerable to attacks.


1. The Dangers of Public Wi-Fi Connections

The use of public Wi-Fi networks by employees can expose sensitive company data to interception. Malware infections, often more common on personal devices, can spread to the corporate network, while lost or stolen devices can lead to unauthorized access to company data.

A Forbes study showed that 40% of respondents had their data compromised while on a public Wi-Fi connection. The majority of these individuals experienced this issue while they were using public Wi-Fi at an airport or restaurant.


2. Compliance and Legal Issues

BYOD policies can inadvertently lead to non-compliance with data protection laws like GDPR and PIPEDA. When employees use their personal devices for work purposes, it becomes challenging to enforce data protection policies uniformly.

This situation can result in legal issues, especially if a security breach occurs. Companies must navigate these legal waters carefully to avoid hefty fines and reputational damage.


3. BYOD Management: A Technical Tightrope

Managing various personal devices within a corporate network is a highly complex task. IT departments must ensure that all devices, regardless of their operating systems or models, comply with the company’s security policies.

This requirement often means implementing Mobile Device Management (MDM) and Mobile Application Management (MAM) solutions, which can be both costly and time-consuming.

Additionally, ensuring software and hardware compatibility across different devices adds another layer of complexity.


4. The Burden on IT Support

BYOD policies can significantly increase the workload of IT departments. They must provide support for a wide range of devices and troubleshoot issues specific to various operating systems and hardware configurations.

This increase in workload can strain resources and divert attention from other critical IT functions.


5. Weak Passwords: A Gateway to Security Breaches

One of the most overlooked yet critical BYOD risks is the use of weak passwords. Personal devices often lack stringent password policies, making them vulnerable to brute-force attacks.

Employees might use easily guessable passwords or reuse passwords across multiple accounts, including their work-related ones. In fact, a Google poll found that one in eight adults used the same password for all of their online accounts.

This practice significantly increases the risk of a security breach, as a compromised password on a personal device can lead to unauthorized access to sensitive company data.

6. Outdated Software: Leaving the Door Open

Another significant risk in a BYOD environment is the use of outdated software on personal devices. Employees may neglect to update their operating systems or applications, leaving known vulnerabilities unpatched.

These security gaps can be easily exploited by cybercriminals to gain access to the corporate network. Ensuring that all BYOD devices are regularly updated is crucial for maintaining device security and protecting against malware and other cyber threats.


7. Mixing Work and Personal Data: A Recipe for Disaster

The blending of work and personal data on the same device poses a unique challenge in BYOD scenarios. This mix can lead to accidental data leaks, where personal activities compromise company data.

For instance, an employee might inadvertently share sensitive information through a personal email or cloud storage service.

Additionally, this entanglement can complicate data management and legal compliance, especially when dealing with a data breach or a security breach involving personal data.


Mitigating BYOD Risks: Practical Steps to Follow

To mitigate the risks of BYOD, companies should implement comprehensive BYOD policies that clearly define acceptable use and security protocols.

Regular training and awareness programs can educate employees about the importance of device security and the proper handling of company data.

Implementing security solutions like encryption, VPNs, and password-protected access can further secure data on personal devices. Regular audits and updates of security measures are also crucial to keep pace with evolving threats.
