Mobiles and employees: Security tips

The more mobile devices a business uses, the The attack surface for cybercriminals is getting biggerAccording to the report published by global cybersecurity company ESET on the  Threats against 1^ο semester of 2024, more and more Android malware is being released that steals financial information, personal data, and is even used for deepfake video scams. At the same time, phishing attacks and other scams are becoming more common.

The best defense is prevention, warns ESET, as it believes it is important to stop threats before they enter a company's network. With this strategy, companies can significantly reduce risk and protect their mobile devices. This way, mobile devices remain valuable tools and not weak links that open the door to attacks.

Mobile threat prevention

The following practices will help businesses protect their employees, and by extension the company itself, from evolving cyberthreats.

1. Implement a powerful Mobile Device Management solution (MDM)

Mobile Device Management (MDM) is critical to securing and controlling corporate devices. It allows you to enforce security policies, monitor usage, and remotely lock or wipe a device if it is lost or stolen. MDM software can also centrally control apps, software updates, and access permissions, ensuring compliance with corporate security protocols.

2. Implement multi-factor authentication (MFA)

Multi-factor authentication (MFA) is a simple but effective security measure. It requires employees to verify their identity with two or more methods, such as a one-time code or fingerprint scan. This ensures that only authorized users have access to sensitive information.

3. Encourage the use of secure networks

Public Wi-Fi networks are notoriously vulnerable and a common target for attacks. Instead, provide your employees with secure alternatives, such as virtual private networks (VPNs), which encrypt their internet traffic and reduce the risk of data being intercepted.

4. Update devices and apps regularly

Outdated software is a major vulnerability. Cybercriminals often exploit known vulnerabilities in outdated operating systems and applications. Make sure your employees regularly update their devices and applications, or better yet, automate the process through MDM.

5. Encrypt sensitive data

Encryption is essential for protecting corporate information. Whether data is stored or transmitted, it must be encrypted so that, even in the event of a device compromise, it remains secure. Most modern devices have built-in encryption capabilities, which can be managed through MDM. This is especially critical in industries such as finance and healthcare.

6. Educate your employees about mobile security threats

No matter how advanced your security systems are, the human factor remains crucial. Regularly train your staff on the latest threats, such as phishing, malware, and social engineering attacks. Training should include practical tips for identifying suspicious messages, as well as instructions on what to do if a device is lost or compromised.

7. Use Mobile Threat Defense (MTD) solutions

Mobile Threat Defense (MTD) solutions offer an additional layer of protection, detecting and mitigating threats such as malware, network attacks and application vulnerabilities in real-time. ESET Mobile Threat Defense provides features such as Anti-malware, Anti-phishing and Anti-theft, while seamlessly integrating with the ESET PROTECT platform, enabling centralized monitoring and management of all mobile devices.

8. Restrict access to sensitive information

Not all employees need access to all company data. Applying the principle of “least privilege” ensures that users only have access to the information they need to do their job. Role-based access controls (RBAC) help enforce these restrictions, adding another layer of protection.

Reducing cyber risks

By implementing these mobile security tips, you can reduce the risk of cyberattacks and protect your company's sensitive data. Cyber ​​threats are constantly evolving. By prioritizing mobile security, you stay one step ahead and maintain a safe digital environment.
