As a result, mobile devices have become an easy target for hackers to access sensitive business data. Hence, device security has become a top priority for businesses. So, it is the business owner’s responsibility to make sure his/her devices are secure. This means taking measures such as updating software, implementing firewalls, and enforcing strong passwords.

Mobile device security best practices

1. Use strong passwords and two-factor authentication

One of the simplest and most effective ways to secure mobile devices is by using strong passwords and two-factor authentication (2FA). Passwords and 2FA secures access to devices and data, making it difficult for unauthorized personnel to gain access to sensitive information.

To create a strong password, one should use a combination of upper- and lower-case letters, numbers, and symbols. Moreover, passwords should not be the same for multiple accounts and should be changed frequently. Implementing Identity and Access Management (IAM) can also be beneficial to control access to data. There are different types of 2FA, such as text message verification, push notifications, and hardware tokens. Companies can choose the type of 2FA that suits their business needs.

2. Keep apps and software up-to-date

Keeping mobile apps and software up-to-date is essential to ensure the latest security patches and fixes are installed. It helps prevent hackers from exploiting vulnerabilities in outdated software and applications. Also, users can check for updates manually or set automatic updates to keep their devices secure.

3. Implement Firewall protection

Firewalls are network security devices that help prevent unauthorized access to a network. Implementing firewalls on mobile devices can protect them from network-based threats, such as malware and viruses.

Types of firewall

Network Firewall

A network firewall is a security system designed to prevent unauthorized access to a computer network. It is typically placed at the boundary between an internal network and the Internet. Network firewalls use a set of rules to filter traffic coming into and out of the network.

Host – based firewall

A host-based firewall is a type of firewall that is installed on a single host or device, such as a laptop, desktop, or server. Unlike network firewalls, which control access to an entire network, host-based firewalls control access to a single device. Host-based firewalls can be particularly useful for laptops and mobile devices that frequently move between different networks.

Application firewall

An application firewall is a type of firewall that monitors and controls incoming and outgoing traffic based on the specific application or service. It is designed to protect against attacks that target specific vulnerabilities in applications, such as web-based attacks. Application firewalls can be software-based, and they work by inspecting the data that is sent and received by an application to determine if it is malicious or not. Application firewalls are typically deployed alongside network and host-based firewalls for layered security.

4. Install antivirus and anti-malware software

Installing antivirus and anti-malware software is crucial in preventing malicious software from infecting mobile devices. Antivirus software detects and removes viruses, while anti-malware software helps detect and remove malware. There are different types of antiviruses and anti-malware software available in the market, and businesses should choose the one that suits their needs.

5. Use a device management solution

A device management solution (MDMs or UEMs) can be an effective step to secure your business data. This type of solution allows you to manage and control the devices that are accessing your business data, which can help to minimize the risk of data breaches and other security incidents. Furthermore, with a device management solution, you can enforce security policies across all the devices that are accessing your business data. This can include policies around password requirements, device encryption, remote wipe capabilities, etc.

6. Encrypt sensitive data

Data encryption is a method of securing data-at-rest by converting it into an unreadable format. Thus, implementing data encryption is essential for businesses that deal with sensitive information. There are different types of data encryption, such as symmetric encryption and asymmetric encryption. Users can encrypt data using different software, such as BitLocker and VeraCrypt.

7. Use Virtual Private Networks (VPNs)

VPNs are a secure way of accessing company networks remotely. VPNs create an encrypted connection between the user’s device and the company’s network, making it difficult for hackers to intercept the data. There are different types of VPNs, such as SSL VPNs, remote access VPNs, IPsec VPNs, etc.

8. Remote lock and data wipe

Remote lock and data wipe are crucial features that help prevent data breaches in case of lost or stolen devices. IT administrators can remotely lock or wipe devices to prevent unauthorized access to sensitive business data. Remote lock and data wipe features are available in UEM solutions, and businesses can also use mobile device management software to remotely manage devices.

9. Conduct regular security audits

Regular security audits can help businesses identify vulnerabilities in their mobile devices and take necessary actions to address them. Security audits can be conducted using different tools, such as vulnerability scanners and penetration testing. Businesses should also ensure that their security policies are up-to-date and comply with industry standards and regulations.

10. Educating employees

Educating employees on mobile device security best practices is essential in preventing data breaches. Furthermore, employees should be trained on how to use mobile devices securely, such as avoiding using public Wi-Fi and not sharing passwords. They should also be educated on the importance of data security and how to report security incidents to the IT department.


The mobile device security best practices mentioned in this blog are not exhaustive, and businesses should conduct a risk assessment to identify their specific security needs. Moreover, businesses should regularly update their security policies and procedures to keep up with the latest security threats and trends.

UEMs: A one-stop solution

Features of UEM that help in data loss prevention

Password policy

A password policy helps in data loss prevention by requiring users to create strong and unique passwords, which are difficult for hackers to guess or crack. This reduces the likelihood of unauthorized access to sensitive data and systems. Furthermore, password policies also enforce regular password changes and prohibit the use of commonly used or easily guessable passwords. UEM solutions enable IT administrators to set the password policies, such as password length and complexity, to prevent unauthorized access to mobile devices.

App updates

App updates help in preventing data loss by fixing security vulnerabilities, bugs, and glitches in the app. This reduces the risk of data loss or unauthorized access caused by the exploitation of these vulnerabilities. Furthermore, app updates also improve the app’s functionality and performance, which helps to prevent data loss due to app crashes or errors.
