BYOD Risks and How to Avoid Them


The increasing trend of BYOD (Bring Your Own Device) in today’s corporate landscape is gaining popularity, providing significant benefits in terms of flexibility and efficiency. Yet, this trend brings its own set of challenges.

The ability to access company information on personal devices is unquestionably convenient, but it also presents various security risks associated with BYOD.

“BYOD can be amazing or terrifying. You need to weigh the risk/benefit.” says  Michael Kourkoulakos, CEO of NENS. “It offers flexibility and efficiency on one side, but on the other, it introduces real security risks we can’t ignore.

According to research by Cybersecurity Insiders, the foremost concern regarding BYOD is the potential for data loss.

In this blog, we aim to delve into these issues, offering vital information to help you confidently and securely manage the BYOD environment in your business.


Before We Dive In…What Exactly is BYOD?

BYOD allows employees to use their personal devices, such as smartphones, tablets, or laptops, for work-related tasks. This shift towards BYOD is not just about cutting costs, as often perceived, but is driven by several other factors.

Here are some insights from a study that found:

Boosting Mobility (63%): One of the biggest advantages of BYOD is enhanced mobility. It allows employees to work efficiently from anywhere, offering a level of flexibility that traditional setups can’t match.

Enhancing Employee Satisfaction (56%): Employees tend to be more satisfied when they can use their own devices. They’re already comfortable and familiar with their personal gadgets, which can lead to a more relaxed and efficient work environment.

Increasing Productivity (55%): Familiarity with personal devices can significantly boost productivity. Employees often find it easier and quicker to complete tasks on devices they use regularly.

The preference for personal devices is so strong that 89% of employees would consider a lower salary if it meant they could choose their work device.

BYOD offers some pretty significant perks. It helps save on expenses, ramps up employee performance, and positively impacts employee mobility and morale. That said, there’s a catch: keeping everything secure can be a challenge.


7 Biggest BYOD Security Risks

1. Data Security Concerns

When employees access company data on their personal devices, it might unintentionally create opportunities for cyber threats. Devices that aren’t adequately secured can fall prey to various risks, such as:

Malware Risks: Harmful software aimed at causing damage or unauthorized access can enter through unverified app downloads or accessing unsafe websites.

Phishing Threats: Deceptive emails or links can lure users into divulging sensitive information. The personal usage of BYOD devices might lead to a relaxed attitude towards email and web security, increasing vulnerability to such scams.

2. Handling Device Loss or Theft

It’s a given that mobile devices, BYOD included, are generally less secure physically compared to those that stay within an office environment. Alarmingly, 41% of data breaches happen due to devices being lost or stolen. When phones or laptops with crucial data go missing, they can become a treasure trove for cybercriminals. Here are the main reasons for concern:

Easy Access to Data: If a device isn’t protected with strong passwords or biometric security, it’s all too easy for someone who finds it to access its contents.

Risk of Remote Exploitation: Lost devices are a potential gateway for cybercriminals to get their hands on sensitive company information, leading to significant financial and reputational damage.

3. Challenges With Inconsistent Software Updates

One of the key issues with BYOD is the use of devices with outdated operating systems or applications. These older systems can have vulnerabilities ripe for exploitation:

Security Gaps: When updates lag, devices don’t receive important security patches, leaving known vulnerabilities open. Hackers are quick to exploit these gaps, often before employees or their companies can patch them.

Compatibility Issues: Outdated apps or operating systems can lead to conflicts with company software, affecting employee productivity and putting extra pressure on support staff.

4. Device Incompatibility Complications

The variety of devices and software in BYOD scenarios can overextend corporate IT resources, creating additional risks:

Increased IT Workload: Supporting a wide array of devices can overburden IT teams, diverting their attention from other critical tasks.

5. Risks of Public Wi-Fi Usage

With over 60% of mobile workers regularly using public Wi-Fi, they face several security risks. These networks are often unprotected, making them prime targets for data breaches. Often, the vulnerability of public Wi-Fi stems from the absence of robust security tools typically found in controlled corporate environments. Many public networks lack industry-standard encryption, firewalls, and intrusion detection systems. This makes them susceptible to breaches, as employees connecting to these networks may inadvertently expose company data.

Risk of Data Eavesdropping: Unsecured networks allow cybercriminals to easily monitor data transmission, capturing sensitive company information.

Man-in-the-Middle Attacks: Attackers can intercept and potentially alter the communication between two unknowing parties, posing a serious security threat.

6. Blending Personal and Business Data

The habit of employees storing both personal and business data on their devices presents a unique challenge in BYOD security risks. Ensuring sensitive company information remains protected in such situations is complex. Having a DLP policy and enforcement in place can greatly reduce the risk. The main concerns are:

Data Handling Complications: Monitoring and applying data backup, retention, or deletion policies becomes significantly more difficult when personal and business data are stored together on a single device.

Risk of Data Exposure: If a personal aspect of an employee’s BYOD device, such as their social media, is hacked, it could lead to unauthorized access to both their personal and company data.

7. Risks of Malicious Apps

Some apps have no place on your employees’ devices, especially when they pose a security risk.

Take, for instance, the Pokemon Go craze. Amidst its popularity, a slew of fake and malicious apps emerged. Deceptive apps with names like “Pokémon Go Ultimate,” “Guide & Cheats for Pokémon GO,” and “Install Pokémongo” surfaced to capitalize on the trend.

Device Takeover Risks: Some malicious apps can gain control over a user’s mobile device, potentially leading to surveillance, unexpected charges, or the loss of personal or work-related information.

Importance of Safe Downloads: Employees should be trained on the best practices for app downloads, emphasizing the need to stick to official app stores. Many risky apps are downloaded from websites pretending to be genuine or alternative versions of popular applications.
