How to protect rugged handhelds from cyber attacks

In an increasingly interconnected world, rugged mobile devices have become an indispensable tool in many sectors and industries. From field service technicians to military personnel, the devices offer unsurpassed durability and functionality in demanding environments. Despite their durability, they are just as vulnerable as any other device to the rise of cyber threats, so it’s vital to keep up to date with the latest security measures.

Rugged handhelds, like all other digital devices, can be the target of malicious cyber-attacks. Data breaches, malware and phishing attempts pose a high risk. To keep these devices secure, it is vital to understand their vulnerabilities.

This article will give you some practical tips on how to protect your rugged handhelds from cyber intrusions and attacks, and ensure the security of your sensitive data.

5 simple security measures for rugged handhelds

Most people think that antivirus software helps prevent cyber threats, but it is not always enough. Here are five other things your company can do to keep your rugged handhelds safe.

• Use two-factor authentication: using two-factor authentication adds a second layer of protection to your password. Using simple text message verification or an authentication app, you can more than double your security.
• Software updates: keep your operating system and the software on your devices and the apps you’ve installed up to date. Updates often fix security vulnerabilities and allow you to take advantage of the latest security features.
• Wi-Fi and VPN security: use secure, trusted Wi-Fi and avoid open or unsecured networks. If your rugged handheld needs to be connected to a public network, make sure you are using a secure VPN (virtual private network). Passwords and personal data must be secured.
• Data backups: regularly back up data on rugged handhelds to protect them from data loss. Securely store backups offline or in the cloud, away from potential cyber threats.
• Implement Mobile Device Management or MDM: Using MDM is a great solution to improve security and streamline device management. MDM solutions allow centralised control, enabling features such as remote device tracking, configuration and policy enforcement.

5 things you need to add to your device management policy

It is important to establish and enforce comprehensive device management policies, including access control, password requirements and a list of allowed applications, as well as cyber security. Make sure all employees are aware of how to use the device wisely. Keep them educated and trained on the latest cyber security threats and best practices.

• Strong passwords: implement strong, unique passwords for each device. Yes, that means no names, no birthdates and the use of hard-to-remember combinations of upper and lower case letters, numbers and symbols.
• Safe browsing: educate users on safe browsing practices, stressing the importance of avoiding suspicious sites or clicking on unfamiliar links.
• Phishing awareness: train users to identify phishing attempts, including email and text message scams. Advise them to refrain from sharing personal or sensitive information through untrusted sources.
• Labelling apps: have a strict policy on which apps users are allowed to download, and make sure they come from trusted sources such as official app stores. Warn employees against downloading apps from third-party sources and avoid granting excessive permissions that could compromise the security of the device.
• Bluetooth security: disable the Bluetooth connection when the device is not in use and never pair it with unknown or untrusted devices. Edit the settings of your devices so that they cannot be detected to prevent unauthorised connection attempts.
