Part 5 : Best Practices for Mobile Device Security

Here are a few recommended methods for enhancing enterprise mobile security that you can apply to minimize the likelihood of your mobile devices being vulnerable to cyber-attacks.

1Enforcing Strong Password Policies and Authentication

One way to make it challenging for unauthorized individuals to access any device is by creating a unique combination of letters, numbers, and symbols. To ensure a strong password, users should be required to choose passwords that are at least eight characters long and include a mix of uppercase and lowercase letters, numbers, and special characters.

In addition to strong passwords, users can add an extra layer of security by using biometric authentication features like fingerprint scanners or facial recognition. While the "remember me" feature on apps may be convenient, it increases the risk of password spoofing and unauthorized access to sensitive information. Therefore, employees should also be educated to avoid using this feature and keep sensitive information secure.

2Device Encryption

If you deal with sensitive information on mobile devices, it's best to keep it secure. Full disk encryption (FDE) is an effective solution for data protection. It encrypts all data on a device's storage, making it unreadable without the correct authentication key. Even if the hard drive is removed and inserted into another machine, the data remains inaccessible without the encryption key.

However, it's important to note that encryption alone isn't enough to guarantee security on smartphones and tablets. Encryption keys can still be stolen, and cold boot attacks can retrieve them. To reduce these risks, it's essential to properly secure encryption keys, implement strong password policies, and limit access to them.

3Remote Wipe

Remote wipe is a security tool that allows a network administrator or device owner to remotely delete data from a computing device. This feature is especially useful when a device is lost or stolen. If the device falls into the wrong hands, remote wipe ensures that sensitive data and information are not compromised.

4Configuring Secure Network Access

Connecting to public Wi-Fi networks can be risky as it exposes your device to potential attacks from hackers and malware. Cybercriminals can easily intercept your traffic and steal sensitive information like passwords, credit card details, and bank account information.

To keep your enterprise mobile security safe while using public Wi-Fi, using a VPN to encrypt your activity is a great approach. However, even with a VPN, risks still exist, making it necessary to configure your devices for secure network access using trusted methods like SSL/TLS encryption. By taking these steps, you can reduce the risk of a breach and keep your sensitive data secure.

5Implementing Device and Data Backup

Planning for unexpected incidents is vital, and creating backups of mobile device data is one such measure. Despite taking all necessary precautions, it's still possible to lose important data, such as cherished memories and contacts, due to accidents. Using automated backup services is a solution to this issue. Several popular cloud storage options such as Google Drive, iCloud, or OneDrive provide secure and convenient ways to store your backup data.
