Mobile security, or mobile device security, is the protection of smartphones, tablets, and laptops from threats associated with wireless computing. More people than ever access the internet using mobile devices, such as laptops, tablets and smartphones with desktop-computer capabilities. With this explosive growth in the use of mobile devices and applications comes an increasing number of threats to mobile security.

In a nutshell, mobile security involves protecting smartphones, tablets, and laptops from cyber threats such as data loss, credential theft, account compromise, and so forth.

Why Is It Important?

With the increasing number of people using mobile devices either for work or daily use, mobile internet traffic has become the dominant form of web browsing over desktops. Mobile devices have a much bigger attack surface than desktops, making them a more significant threat to corporate security. The malware targeting these operating systems has also increased.

In this article, we are going to dive deeper into different aspects of mobile security.

Authentication and Onboarding

Authentication is the process of verifying a user’s identity, while onboarding is the process of registering a new user and providing them with access to your app or service. Strong authentication is essential for protecting your mobile app from unauthorized access. There are a number of different authentication methods for app developers to use, including:

  • Passwords: Passwords are still the most common form of authentication, but they are also the weakest. Passwords should be at least 8 characters long and contain a mix of uppercase and lowercase letters, numbers, and symbols.
  • Multi-factor authentication (MFA): MFA adds an additional layer of security to your authentication process by requiring users to enter a code from their phone or another device in addition to their password.
  • Biometrics: Biometrics, such as fingerprints, facial recognition, and voiceprints, can be used to provide a more secure and convenient authentication method.

Onboarding is also an important aspect in that you ensure that correct information is collected such as the user’s name, email address, phone number, address, date of birth and perhaps a government-issued ID. This information can be used to verify the user’s identity and to prevent fraudulent accounts from being created. By implementing strong authentication and onboarding practices, you can help to protect your mobile app from unauthorized access and fraud.

In addition, use a variety of authentication methods. Don’t rely on passwords alone. Use a combination of passwords, MFA, and biometrics to provide a more secure authentication process. Also encourage user’s to change their passwords regularly, perhaps implement a policy of every 90 days.

Users should also be educated on strong security practices. Make sure that users know how to create strong passwords, how to use MFA, and how to protect their personal information.

For organizations with a security team, ensure that you monitor your authentication logs for suspicious activity. If you see any suspicious activity, such as multiple failed login attempts from different IP addresses, investigate immediately.

Rogue Access Point Detection

Rogue access points (APs) are unauthorized Wi-Fi access points that are installed on a network without the knowledge or permission of the network administrator. Rogue APs can be used to steal data, inject malware, or launch denial-of-service attacks. There are a number of ways to detect rogue access points:

  • Rogue APs often have a weaker signal strength than legitimate APs. This is because they are often not connected to a wired network and are therefore relying on the power of their own batteries.
  • They may be using a SSID that is similar to the SSID of a legitimate AP. This can be done to trick users into connecting to the rogue AP.
  • They may not be using any security settings, or they may be using weak security settings. This makes it easier for attackers to gain access to the network.
  • Rogue APs are often located in areas where there are a lot of people, such as airports, coffee shops, and hotels. This is because they are more likely to be successful in luring users into connecting to them.

To protect your mobile device from rogue APs, using a rogue AP detection app might prove useful. Users should only connect to Wi-Fi networks they trust. In addition, using a strong Wi-Fi password will make it more difficult for attackers to gain access to your network.

Wireless Secure Protocols

Wireless secure protocols are used to protect data that is transmitted over wireless networks, such as Wi-Fi. These protocols use encryption to scramble the data so that it cannot be read by unauthorized parties. Let’s take a look at some protocols used in wireless security:

  • WEP (Wired Equivalent Privacy): WEP is the oldest and least secure wireless security protocol. It is vulnerable to a number of attacks and should not be used.
  • WPA (Wi-Fi Protected Access): WPA is a more secure wireless security protocol than WEP. It uses a stronger encryption algorithm and is less vulnerable to attacks.
  • WPA2 (Wi-Fi Protected Access 2): WPA2 is the most secure wireless security protocol available. It uses the strongest encryption algorithm and is the most resistant to attacks.
  • WPA3: WPA3 is the latest wireless security protocol. It offers even more security features than WPA2, such as improved protection against brute-force attacks and denial-of-service attacks.

Mobile App Automated Scanning

This is a security practice that uses automated tools to scan mobile apps for security vulnerabilities. However, it is important to note that automated scanning tools are not perfect. They can miss some vulnerabilities, and they can also generate false positives. It is important to use automated scanning tools in conjunction with other security practices, such as manual code review, to get the best results.

This security practice can help to identify security vulnerabilities in mobile apps early in the development lifecycle, when they are easier and less expensive to fix, while improving the overall security posture of apps.

Dynamic Mobile App Analysis

Dynamic mobile app analysis is a security testing method that involves executing the app in a real or simulated environment to identify security vulnerabilities. This type of analysis can be used to find vulnerabilities that are not visible in static analysis such as vulnerabilities in memory corruption, code execution and API abuse.

This type of analysis can be performed manually or using automated tools. Manual analysis involves executing the app and manually inspecting the code and behavior for vulnerabilities. Automated analysis uses tools to automate the process of executing the app and inspecting the code and behavior for vulnerabilities. However, it is important to note that dynamic analysis is not perfect. It can miss some vulnerabilities, and it can also generate false positives. It is important to use dynamic analysis in conjunction with other security practices, such as static analysis and manual code review, to get the best results.

Secure Coding Practices

This refers to set of guidelines that developers can follow to write secure code. These practices help to prevent security vulnerabilities from being introduced into the code.

Some of the key secure coding practices that developers should adhere to include input validation, data encryption, session management, code quality and code review.

Mobile Penetration Testing

This is a security assessment that aims to identify and exploit security vulnerabilities in mobile apps. This type of testing is performed by security experts who use a variety of techniques to gain unauthorized access to the app, steal data, or disrupt its functionality. Mobile penetration testing can be performed on both native and hybrid apps.

This technique coupled with both static and dynamic analysis, can also be done using, fuzz testing(A technique that involves feeding the app with invalid or unexpected input), reverse engineering(The process of decompiling the app’s binary code into its source code) or even social engineering.

Secure Code Review

Secure code review is a security practice that involves having another developer review the code for errors and security vulnerabilities. This helps to find and fix vulnerabilities before they are released into production. By identifying and fixing security vulnerabilities, secure code review can help to protect mobile apps from attack.

OWASP Mobile Top 10

The OWASP Mobile Top 10 is a list of the most critical security risks to mobile applications. The list is updated regularly to reflect the latest threats and vulnerabilities.


Mobile security is a complex topic, but it is important to take steps to protect mobile devices from unauthorized access, use, or disclosure of data. By following the best practices outlined in this blog post, you can help to keep your mobile devices safe.

In addition to the topics mentioned above, there are a number of other considerations for mobile security, such as:

  • Using a secure development lifecycle (SDLC). The SDLC should include security practices such as secure coding, code review, and penetration testing.
  • Using a mobile security testing framework. A mobile security testing framework can help to automate the process of identifying and fixing security vulnerabilities.
  • Keeping mobile apps up to date. Mobile app vendors often release security updates to fix vulnerabilities. It is important to keep mobile apps up to date to protect against known vulnerabilities.
  • Educating users about mobile security. Users should be educated about the risks of mobile security and how to protect themselves.

By taking a comprehensive approach to mobile security, you can help to protect your organization or yourself from data breaches and other security incidents.
