5 Essential Mobile Phone Security Practices for Businesses

Understanding the Mobile Threat Landscape

The landscape of mobile security threats is vast and dynamic, posing significant risks to businesses. Malware and phishing attacks, device theft and loss, and unsecured Wi-Fi networks are among the prevalent threats.

Malicious attacks, particularly phishing attempts, have become common. According to Cyber Security Breaches Survey 2022, of the 39% of UK businesses who identified an attack, the most common threat was phishing attempts (83%). Of the 39%, around one in five (21%) identified a more sophisticated attack type such as a denial of service, malware, or ransomware attack.

Device theft and loss are also prevalent, with over 196,000 reported cases of personal mobile device theft in England and Wales from April 2022 to March 2023. The Prey Project's Mobile Theft and Loss Report indicates that over 60% of incidents involve misplaced devices, highlighting the need for robust security measures to mitigate any unforeseen circumstances.

Unsecured Wi-Fi networks present another significant risk. With 35% of people accessing public Wi-Fi three to four times a month, the exposure to potential threats is substantial, where hackers can intercept and retrieve important data. Recognizing and addressing these specific threats is paramount for businesses operating in mobile environments.

Best Mobile Security Practices for Businesses

Use Mobile Device Management (MDM) features to your advantage

Implementing an MDM solution is fundamental for securing mobile devices within a business. These platforms offer centralized control and extensive capabilities, including provisioning, configuration, and monitoring. Security is also a crucial element for MDM where key features include:

• device encryption, a vital feature where sensitive data is secure
• complex password settings and enforcement
• network access controls, to regulate end–users from falling into malicious traps via unprotected internet access
• remote locate and wipe functionalities, ensuring that if anything goes wrong, there’s swift immediate action to reduce repercussions

Enforce Strong Password Policies

IT administrators should also encourage and enforce the use of complex passwords, avoiding easily guessable combinations. MDM tools can enforce regular password updates and provide options for using password managers. Implementing multi-factor authentication also reduces the risk of unauthorized access. MFA comes in multiple ways, including:

• Time based One-Time Passwords (OTP)
• Biometric authentication including fingerprint & face identification
• Traditional MFA, where a user receives a code from a secondary device to include with their password.

Regularly Deploy Software Updates and Security Patches

Timely updates are crucial for a business to stand against the latest virus and malware threats. Google, Apple, and other OEMs provide their own security patches to their supported devices; however, each company has their own level of frequency of patches deployed within a certain time period. This can lead to vulnerabilities in a business’s fleet being exposed to immediate threats. With over 450,000 new malicious programs registered daily, businesses must ensure their devices receive the latest security patches.

Automation of update processes via MDM tools enhances efficiency and helps in maintaining a robust security posture.

Train employees on the latest preventive measures

Educating employees on the best practices for security is crucial. Regular training events can empower employees, contributing to an overall security-conscious workplace. Employees should be trained on:

• recognizing phishing attacks by email and SMS messages, including ways to identify a verified & authentic sender
• being cautious in sending passwords and account details through unencrypted communication channels
• implementing an extra layer of protection with MFA procedures
• avoiding personal details being given over the phone from suspected scam calls
• reporting any suspicious incidents

Proper Wi-Fi usage in public

Discourage the use of public and unsecured Wi-Fi networks, as they pose significant risks. Statistics show that four in 10 individuals have had their information compromised while using public Wi-Fi, with airports and restaurants being common locations for such incidents. End users should:

• Avoid using Wi-Fi access points that aren’t password protected
• Control your actions; if you believe that sensitive data should be sent, find alternative options that don’t leave you vulnerable
• Implement virtual private network (VPN) solutions that enhance the security of network connections. For more on VPN, please read the official Device Security Guidance from the UK’s National Cyber Security Centre

Conclusion

In conclusion, the evolving mobile threat landscape necessitates a proactive approach to security. The outlined practices—MDM implementation, strong password policies, regular software updates, employee training, and safe Wi-Fi usage—lay the foundation for a robust mobile security strategy. Ongoing vigilance and adaptation to emerging threats are crucial for maintaining a resilient cyber defense posture.
