In 2019, an employee at a major U.S. financial firm mistakenly connected their work phone to an unsecured public Wi-Fi network. Within hours, a cybercriminal accessed sensitive customer data, resulting in a costly data breach and severe reputation damage for the company. This incident highlights a critical vulnerability facing modern businesses: mobile device security.

As businesses increasingly rely on mobile devices for work, the potential risks multiply. Smartphones, tablets, and laptops are essential for communication, data access, and collaboration but are equally attractive targets for cyberattacks.

Securing mobile devices has become imperative for businesses of all sizes, especially in a world where remote work and bring-your-own-device (BYOD) policies are the norm. A breach can lead to loss of sensitive data, legal complications, and financial losses. This article presents ten best practices for enhancing mobile device security within your organization, ensuring that your business and customer data remain safe.

Top 10 Mobile Device Security Practices

1. User Authentication
Strong user authentication is a foundational security measure. Implementing multifactor authentication (MFA) significantly reduces unauthorized access to corporate data on mobile devices. MFA requires users to verify their identity with a second factor, such as a fingerprint, PIN, or a one-time code sent to their phone, alongside their password. Simple password protections are often inadequate, as they can be easily guessed or breached through phishing. By adding MFA, businesses can dramatically lower the risk of unauthorized access.

2. App Management
App management involves controlling the applications that can be installed or accessed on company-owned or BYOD devices. Allowing only trusted and necessary apps reduces the likelihood of malware infiltrating the device. It's also essential to keep apps updated, as developers frequently release patches to fix vulnerabilities. Mobile device management (MDM) solutions can enforce app policies remotely, blocking access to unauthorized apps and managing updates to prevent potential exploits. App management is a proactive way to reduce vulnerabilities and maintain control over mobile devices in the workplace.

3. Data Backup
Regular data backups ensure that critical business information is never lost, even if a device is compromised. Backups should be automated and stored in a secure, encrypted format. Data loss can occur through device theft, hardware failure, or accidental deletion, so backups provide a safety net that allows data recovery without significant downtime. Cloud storage is commonly used for backup, but local secure servers or external drives can also serve as additional layers of redundancy. Routine data backups help maintain business continuity and protect against loss of valuable information.

4. BYOD - Data Wipe
Bring-your-own-device (BYOD) policies are popular among businesses, but they introduce unique security challenges. A critical security measure is the ability to remotely wipe data from a device if it's lost, stolen, or when an employee leaves the company. BYOD data wipe capabilities prevent unauthorized access to sensitive company data on personal devices. This feature, often included in MDM solutions, ensures that employees' personal data remains untouched while corporate data is wiped, allowing companies to maintain privacy and security simultaneously.

5. Use Encryption
Encryption is essential to mobile device security as it protects data both in transit and at rest. By encrypting sensitive data, businesses can ensure that even if a device is accessed by unauthorized users, the information remains unreadable. Most modern mobile devices offer encryption settings that are easy to enable. Businesses should enforce encryption policies for all work devices and ensure that any file-sharing or messaging apps used are encrypted as well. Without encryption, business data is vulnerable to theft and unauthorized access.

6. Disable Wi-Fi and Bluetooth When Not in Use
Wireless connections like Wi-Fi and Bluetooth are common entry points for cyber threats, as hackers often exploit these connections to intercept data or install malware. Educating employees to disable Wi-Fi and Bluetooth when not in use minimizes exposure to attacks such as “man-in-the-middle” (MitM) attacks, where hackers intercept data sent between devices and networks. Additionally, corporate policy can enforce the use of secure networks and ban the use of public Wi-Fi for work-related tasks to mitigate risks further.

7. Use Password Managers
A password manager allows employees to generate, store, and manage complex, unique passwords for every application and device. Strong passwords are crucial for security, but remembering them can be challenging, often leading users to reuse weak passwords. Password managers simplify secure password practices by securely storing all login credentials. Many password managers also support two-factor authentication, adding an extra layer of protection. Ensuring that employees use password managers helps prevent unauthorized access and strengthens overall security.

8. Avoid Public Wi-Fi
Public Wi-Fi networks, often unsecured, are breeding grounds for cyberattacks. To prevent threats, employees should be instructed to avoid connecting to public Wi-Fi networks whenever possible. If employees must use public Wi-Fi, they should use a virtual private network (VPN) to secure the connection. VPNs encrypt data traveling between the device and the network, making it difficult for hackers to intercept or manipulate it. Avoiding public Wi-Fi protects sensitive data from the risks associated with unsecured networks.

9. Keep Corporate and BYOD Devices Updated
Software updates are essential for security, as they often contain patches for vulnerabilities discovered after a product's release. Both corporate-owned and BYOD devices should be kept up-to-date with the latest operating system and app updates. Companies can enforce this through MDM solutions that schedule updates and ensure compliance. Delaying updates leaves devices exposed to exploits that hackers are quick to leverage. Keeping devices updated is a straightforward yet powerful defense against cyber threats.

10. Educate the End Users
User education is one of the most effective ways to enhance security. Employees should be aware of the latest cybersecurity threats and trained to recognize phishing attempts, suspicious links, and signs of malware. Conduct regular training sessions to refresh employees on security practices, covering topics like secure browsing, app permissions, and social engineering attacks. When end-users are informed and vigilant, they act as an essential line of defense, reducing the likelihood of accidental data breaches.

Implement Mobile Device Management (MDM) Solutions

Implementing a Mobile Device Management (MDM) solution is crucial for overseeing and securing mobile devices within a business. MDM solutions provide IT administrators with centralized control over device security settings, app permissions, and data management, which is especially important in managing company-owned or BYOD devices.

Benefits of MDM Solutions

MDM solutions enable businesses to enforce security policies, such as app restrictions, remote data wipes, and device encryption, across all devices. They also streamline app management, allowing IT teams to control which applications are accessible on devices, thus reducing the risk of malware. An MDM solution is essential for managing the lifecycle of mobile devices, from initial deployment to secure decommissioning.

Key Features to Look For in MDM Software

When selecting an MDM solution, businesses should consider features that align with the security practices outlined above:

App Management: Control and restrict app usage, ensure app updates, and block unauthorized applications to prevent malware risks.

Device Policy Enforcement: Enforce policies like disabling Bluetooth or Wi-Fi, requiring password managers, and enforcing screen locks.

Data Wipe and Encryption: Remotely wipe data from lost or compromised devices and enforce encryption policies to protect sensitive information.

Kiosk Mode and Policy Controls: Lock devices into specific applications or functions, ensuring employees use devices strictly for approved business tasks.
