Mobile device security best practices

11th August 2024

In today’s digital-first world, mobile devices are an integral part of both personal and professional life. With businesses increasingly relying on smartphones and tablets for communication, collaboration, and remote work, securing these devices is more critical than ever. Unfortunately, cyber criminals are well aware of this shift and actively exploit vulnerabilities in mobile devices to gain unauthorised access to sensitive data.

We specialise in providing managed IT and cyber security services that help businesses protect their mobile infrastructure. In this blog, we’ll outline the best practices for mobile device security and how we can help safeguard your business from mobile threats.

 

Keep software and operating systems updated

One of the simplest yet most effective ways to secure mobile devices is by keeping software up to date. Operating system (OS) updates frequently include security patches that address vulnerabilities exploited by hackers. Failing to update your device can leave you exposed to known threats.

Best practices:

  • Enable automatic updates to ensure the latest security patches are applied.
  • Regularly check for software updates on both the OS and installed apps.
  • Ensure that security updates are applied promptly across all company-owned devices.

Implement strong authentication methods

Passwords alone are no longer enough to secure mobile devices. Weak or reused passwords are a common entry point for cyber criminals. Implementing stronger user authentication mechanisms is essential.

Best practices:

  • Use multi-factor authentication (MFA) wherever possible.
  • Enable biometric authentication, such as fingerprint scanning or facial recognition.
  • Require strong, unique passwords and implement password management policies.

 

Encrypt your data

Encryption ensures that data stored on a mobile device remains secure even if the device is lost or stolen. Modern mobile operating systems provide built-in encryption features that should be enabled.

Best practices:

  • Ensure full-disk encryption is enabled on all business mobile devices.
  • Use encrypted messaging apps for sensitive communications.
  • Encourage employees to store business data in secure, encrypted cloud environments rather than on local devices.

 

Be wary of public Wi-Fi networks

Public Wi-Fi networks are notorious for being insecure. Cyber criminals can use techniques like “man-in-the-middle” attacks to intercept data transmitted over these networks.

Best practices:

  • Avoid connecting to public Wi-Fi when handling sensitive business information.
  • Use a Virtual Private Network (VPN) to encrypt data transmissions.
  • Educate employees on the risks of public Wi-Fi and encourage the use of personal or company-provided mobile hotspots.
  • Keep mobile devices secure by enabling security features like strong passwords, biometric authentication, and automatic updates.
  • Implement a remote lock feature to protect company data in case a device is lost or stolen.

 

Disable unused features and connections

Many mobile devices have built-in connectivity features that, when left enabled, can become potential attack vectors.

Best practices:

  • Disable Bluetooth, Wi-Fi, and NFC when not in use.
  • Turn off location services for apps that do not require them.
  • Configure devices to “forget” known Wi-Fi networks to prevent automatic reconnections to unsecured networks.

 

Carefully manage app permissions

Carefully managing app permissions is an essential step in protecting your private data and ensuring robust security measures on your devices. Apps often request permissions that go beyond their necessary functionality, and granting excessive permissions can increase the risk of data breaches.

By following the practices below, you can maintain control over your private data and reduce potential vulnerabilities in mobile application management.

Best practices:

  • Only download apps from trusted sources such as the Apple App Store or Google Play Store to minimise the risk of installing malicious software.
  • Review app permissions before installation and deny unnecessary access to sensitive information, such as location, contacts, or camera, unless essential for the app’s function.
  • Use Mobile Device Management (MDM) solutions to control app installations on company devices, ensuring only approved apps are installed and enforcing security measures.

Utilise remote tracking and wiping features

Mobile devices are frequently lost or stolen, making remote tracking and wiping features essential for securing business data.

Best practices:

  • Enable “Find My Device” features on iOS and Android devices.
  • Ensure business-critical data is backed up to a secure cloud environment.
  • Configure MDM solutions to remotely wipe devices in case of loss or theft.

 

Protect against SIM swapping attacks

SIM swapping is a tactic used by cyber criminals to hijack phone numbers and gain unauthorised access to online accounts.

Best Practices:

  • Set up a SIM lock PIN with your mobile carrier.
  • Use app-based authentication (like Google Authenticator) instead of SMS-based 2FA.
  • Be cautious of phishing attempts designed to steal personal information.

 

Conduct regular security training for employees

Human error is one of the biggest security vulnerabilities in any organisation. Regular training ensures that employees are aware of common mobile security risks and how to mitigate them.

Best practices:

  • Educate employees on phishing scams and how to recognise suspicious emails or messages.
  • Encourage employees to report lost or stolen devices immediately.
  • Conduct regular security awareness training sessions.

 

Implement a Mobile Device Management (MDM) solution

A robust MDM solution allows businesses to enforce security policies and manage mobile devices remotely.

Best Practices:

  • Use MDM software to enforce device encryption, password policies, and app management.
  • Enable remote device wiping for lost or stolen company devices.
  • Monitor mobile device activity for potential security threats.
