Mobile security officers and professionals work in unique environments and have defined roles. In this article, we look at some questions that you should expect in a mobile security interview if your application goes through.

Remember, you will also be assessed on other areas other than your experience and skills. You, therefore, need to prepare well before appearing before the interview panel. Let us take a look at these questions:

1.    What Is Your Understanding of Mobile Security?

Mobile security entails protecting devices such as mobile phones, computers, and tablets and the networks they are connected to from any threat or vulnerability brought about by wireless computing. 

2.      How Does Mobile Security Work?

Mobile security is a comprehensive concept that includes device security and end-user practices. Organizations may require devices to have a password/biometric authentication or use mobile device security software. Some end-user practices can include connecting to corporate resources via VPN.

3.      Why Are You Interested in This Role?

I am passionate about device and data protection. This is my fifth year in this field, and I enjoy every bit of it. I believe that I have all it takes to perform exceptionally well, given that my efforts have always been noticed and rewarded in my former workplaces.

Your company can therefore benefit from my services as I also continue learning and bettering myself.

4.      How Would You Know That an Application Is Secure?

There are several qualities that a secure mobile application has. It should require encryption to keep off attackers from reading any wireless communication. It must have expiry sessions to lock out hackers from making malicious requests to the application’s server. It should also have shared secrets only known by the client and server to be used by the client to sign requests.

Lastly, a secure application limits the duration of validity of a request and blocks repeat requests.

5.      You Must Have Interacted With Mobile Security for Android Devices at One Point. What Are the Minimum System Requirements to Look Out for?

Even though both carry their levels of risk, developing software for mobile devices is riskier. This is because mobile applications are usually susceptible to external attacks and can even be bypassed or jailbroken easily, which is common for Android and Apple devices. Once a device has been jailbroken, any experienced hacker will easily access the source code and change or restructure the mobile application.

7.      What Would You Advise Application Developers to Do To Ensure Better Mobile Security for Their Clients?

The mobile industry has rapidly grown in the past few years. As a result, developers have been coming up with applications that users find helpful. However, they should ensure that these applications are secure for end-users. To boost app security, developers should write secure codes and ensure that all the data is encrypted.

They must also use authorized APIs only and exercise caution with libraries. Other measures include using the principle of least privilege, ensuring that session handling is done well, and making use of tamper detection technologies.

8.      What Do You Understand by a System Tuner?

A system tuner is a feature that was introduced to help in optimizing the performance of devices, extend their battery life, and end background applications to free device memory. In Android devices, it first came up in Android Marshmallow, allowing people to hide status icons and show the battery percentage among many other functions.

9.      Do You Prefer Working Alone or In a Team?

In my years in this field, I have come to appreciate more the role of teamwork. I have been in several teams tasked with different projects in mobile security and experienced just how efficient teaming up is. I am, therefore, a good team worker who can get along with diverse people.

However, I also understand that this job may call for independent work at times. I consider myself versatile and would not have problems working alone.

10. Why Should One Have an Alternate Email Address?

An alternative email address plays an important role when one’s phone gets locked. They will need it for the unlock key, which is usually sent in such a case. This does not have to be complicated as your Gmail account will be used as an alternative email address.

Setting up an alternative email address is pretty straightforward. One just needs to go to Settings and select Set Up alternate email address, and it will be up.

11. Why Would You Advise a Client or Mobile User to Have a Trend Micro Account?

A trend micro account has several features that make it highly important. It has parental controls, which will make your device settings secure and also lost device protection. The latter helps you securely locate your mobile device if you lose it, delete its data, or even ring an alarm from a web portal.

12. In Your Experience, What Do You Consider the Role of Activation?

Activating mobile security allows device owners to access several premium features. These include app manager, pre-installation scan, lost device protection, data theft scanner, and parental control. Other features include safe surfing, call blocker, and text blocker.

13. What Do You Understand by Lost Device Protection in Mobile Security?

Lost device protection is a feature that helps protect mobile devices and the data contained in them in case of loss or misplacement. One can remotely trigger an alert, locate the device or wipe any data if it is enabled.

To enable this feature, you will have to activate mobile security in device administrators, which permits remote wipe and uninstall protection. You will be informed that activating the feature allows your mobile security application to wipe all data without warning through a factory reset.

14. What Are Some of The Things That Are Needed to Ensure That Lost Device Protection Work?

Even with this feature activated, one still needs an active GPS and Data/ WIFI connection. These will help trigger a remote alarm and locate the device in case of loss. They will also enable you to erase all the data in your device in cases of theft.

15. In Your experience, Do Mobile Applications Constantly Interact with Internal Servers?

Yes. Most mobile applications maintain their connection to the internal servers all the time, giving the end-user an easy time and high levels of convenience. However, it also comes with one huge disadvantage, which explains why more secure apps have expire sessions. An experienced attacker or hacker can easily access the internal server and jailbreaking it. Limiting such chances fall squarely on the developers, who are often required to think of how their heir mobile applications interact with internal servers.

16. Why Do You Think You Are the Best Candidate for This Position?

I believe that my experience and expertise qualifies me for this job. I have been in mobile security for the last ten years, and therefore, first-hand witnessed some of the changes in mobile security that people enjoy.

I am a team worker who can get well with people of different personalities, a devoted employee, and a person of high integrity. I am sure that I can help your company better.

17. How Can You Protect a Client’s Private Data on Their Smartphones?

The best way of protecting a client’s sensitive data is to write a secure code. Ensure that the given code wipes out the private data from the device once the browsing session expires. If not, your client’s data will remain on the device, making it accessible to hackers.

Therefore, manufacturers and app developers must make sure that they constantly monitor their systems and applications for errors to prevent as many security threats as possible.

18. How Do You Ensure That You Are Updated on Issues Touching on Mobile Security?

Even though mobile security is a relatively new industry, it has one of the highest growth rates I have ever witnessed. As many devices and operating systems modifications emerge, the need for mobile and general device security increases. Therefore, there is a lot of things that one needs to learn about mobile apps dynamics and hacking.

19. What Are the Main Benefits of Mobile Security?

Mobile security benefits both users and administrators. Users can enable mobile security settings in their devices which offers them additional protection of the general device whenever they access applications from their devices.

For administrators, they can view all account activities thanks to the box mobile application management features. They can also manage the sharing and access of content within and outside the company and monitor different users and their files.

20. Having Majored in Mobile Security for Long, I Believe That You Are Conversant with Mobile Security Testing. Could You Please Tell Us What It Entails?

Mobile security testing includes checking for multi-user support while leaving the data between them unscathed. It also consists of the detection/ encryption method for communication of sensitive data, checking for any stored files by unintended users, and detecting sensitive areas in the tested applications to avoid receipt of any harmful content.

21. How Can One Know If an Application Is Safe?

The main way of knowing whether an application is safe or not is by checking its source. You need to download applications from official app stores such as the App Store of the Google Play Store. You also need to check the user reviews before downloading and installing an application and check out the developer of the application. You can also have a mobile security application that will tell you which app is safe and not.

22. What Are Some of The Most Common Threats to Mobile Security?

Some of the most common threats that I have witnessed are potential data leakage by malicious applications, gaps in end-to-end encryption, spyware, viruses, Outdated operating systems, and social engineering. Other threats include unsecure public WIFIs and Internet of Things devices such as wearable tech.

23. How Often Should a Developer Test a Mobile Application

Mobile application testing should be done as frequently as possible. This should happen during development, after the development, before the application is launched, and afterward. The after tests should be as many as possible to help identify upgrades.

24. What Are Some of The Things That One Can Do If Their Device Is Stolen?

Mobile security allows device owners to perform three functions in cases of theft or device loss. One can choose to track the device, wipe out all data from the device or trigger a remote alarm.
