Because of their convenience, phones and tablets have become a universal presence in the modern business world. As usage soars, it becomes increasingly important to take steps to protect your company from mobile threats, both new and old.

The need for proper phone security is no different from the need for a well-protected computer network. According to computer security software company McAfee, cyber attacks on mobile devices increased by almost 600 per cent from 2011 to 2012—and experts expect that number to continue to increase.

Gone are the days when the most sensitive information on an employee’s phone was contact names and phone numbers. Now a smartphone or tablet can be used to gain access to anything from emails to stored passwords to proprietary company data. Depending on how your organization uses such devices, unauthorized access to the information on a smartphone or tablet could be just as damaging as a data breach involving a traditional computer system.

Lost or Stolen Mobile Devices

Because of their size and the nature of their use, mobile devices are particularly susceptible to being lost or stolen. According to CIRA, 3 in 10 organizations have seen a spike in the volume of cyber attacks during the Covid-19 pandemic.

Since most devices automatically store passwords in their memory to keep users logged in to email and other applications, gaining physical possession of the device is one of the easiest ways for unauthorized users to access private information.

To prevent someone from accessing information on a lost or stolen device, the phone or tablet should be locked with a password or PIN. The password should be time sensitive, automatically locking the phone out after a short period of inactivity.

Most devices come with such security features built in. Depending on your mobile provider, there are also services that allow you to remotely erase or lock down a device if it is lost or stolen. Similarly, it is possible to program a mobile device to erase all of its stored data after a certain number of login failures.

Malicious Attacks

Mobile devices are just as susceptible to malware and viruses as computers, yet many businesses don’t consider instituting the same type of safeguards.

Furthermore, it doesn’t matter what operating system the devices have, whether it be Android, Apple’s iOS, Blackberry or Windows Mobile—all are vulnerable to attacks.

As reliance on these devices continues to grow, so will their attractiveness as potential targets. Third-party applications (apps) are especially threatening as a way for malware to install itself onto a device. These apps can purchase and install additional apps onto the phone without the user’s permission. Employees should never install unauthorized apps to their company devices. Apps should only be installed directly from trusted sources.

Hackers can use “ransomware” to restrict a user’s access to their device’s data, contacts, etc, and then demand a ransom to get it back. Even if the user pays the ransom, there is no guarantee that he or she will get the data back. Employees should know to never pay the ransom if this type of software finds its way onto a company device.

A big difference between mobile devices and laptops and other computers is the ability to accept open Wi-Fi and Bluetooth signals without the user knowing. Hackers can take advantage of this by luring devices to accept connections to a nearby malicious device. Once the device is connected, the hacker can steal information at will. To prevent this, make sure all mobile devices are set to reject open connections without user permission.

Mobile Device Security Tips

While the current mobile device security landscape may seem lacking, there are plenty of ways to be proactive about keeping company devices safe from threats.

  1. Establish a mobile device policy
  2. Establish a bring your own device (BYOD) policy
  3. Keep the devices updated with the most current software and antivirus programs
  4. Back up device content regularly
  5. Choose passwords carefully

Establish a mobile device policy

Before issuing mobile phones or tablets to your employees, establish a device usage policy. Provide clear rules about what constitutes acceptable use as well as what actions will be taken if employees violate the policy. Employees must understand the mobile security risks and how they can mitigate those risks. Well-informed, responsible users are your first line of defence against cyber attacks.

Establish a bring your own device (BYOD) policy

If you allow employees to use their personal devices for company business, make sure you have a formal BYOD policy in place. Your BYOD security plan should also include the following practices:

  • Installing remote wiping software on any personal device used to store or access company data.
  • Educating and training employees on how to safeguard company data when they access it from their own devices.
  • Informing employees about the exact protocol they must follow if their device is lost or stolen.

Keep mobile devices updated with the most current software and anti-virus program

Software updates to devices often include patches for various mobile security holes, so it’s best practice to install the updates as soon as they’re available.

There are many options to choose from when it comes to anti-virus software for mobile devices, so it comes down to preference. Some are free to use, while others charge a monthly or annual fee and often come with better support.

In addition to antivirus support, many of these programs will monitor SMS, MMS and call logs for suspicious activity and use blacklists to prevent users from installing known malware to the device.

Back up device content regularly

Just like your computer data should be backed up regularly, so should the data on your company’s mobile devices. If a device is lost or stolen, you’ll have peace of mind knowing your valuable data is safe.

Protect against lost and stolen devices

Because of their size and nature of use, mobile devices are at an increased risk of being lost or stolen. Since most devices automatically store passwords in their memory to keep users logged in to email and other applications, having physical possession of the device is one of the easiest ways for unauthorized users to access private information.

To prevent someone from accessing a lost or stolen device, the phone or tablet should be locked with a password. The password should be time sensitive, automatically locking the phone out after a short period of inactivity. Most devices come with such security features built in, which is something you should consider before purchasing. Depending on your cell phone provider, there are also services that allow you to remotely lockdown or erase a device in the event that it is lost or stolen.

Because of their convenience, smartphones and tablet devices have become a universal presence in the modern business world. As usage soars, it becomes increasingly important to take steps to protect your company from mobile threats, both new and old.
