Why is Mobile App Security a Top Priority for Developers

The current pandemic forced us to stay home due to social distancing measures and such shifts in behaviour increased the demand for mobile apps, both Android and iOS.

Such wide usage comes with security risks although not all users understand the importance — such lack of knowledge can be exploited by cyber attackers.

Mobile apps without security protocols put forth extreme risks to both users and developers as unprotected vulnerabilities may become targets to hackers for malware attacks or data breach.

There are over 4.8 billion mobile phone users and if any virus goes viral, it can be harmful to the global digital community.

Mobile app security must be the top concern as any unsecured mobile app is at high risk level.

What is Mobile App Security?

Mobile app security is the measures of defending a mobile app from fraudulent attacks like malware, hacking or other criminal manipulations.

Different technologies used in mobile app protection target different sorts of cyber threats that a mobile device can pose due to the apps installed in them.

Mobile app security represents the amount of protection an app has from malware, phishing and other harmful hacker crimes.

Android is a good example — being an open framework, it is more vulnerable to MITM attacks (man-in-the-middle), data breaches, or malware assaults as opposed to iOS platform which is exclusive to Apple users.

Reasons to Secure Your Mobile App

Most of the world’s workforce is working remotely nowadays while some companies hire freelance workers that use their own laptop or computer to do the company’s work — such an approach carries risks of attacks.

A single breach is enough to invade the privacy of the company’s system and customers. Hackers’ usual targets are high ranked officers in the company as they hold more valuable data thus it is crucial for developers to inspect the app security — developers have to provide the latest security features to protect user privacy and data.

Mobile app security, if done properly, enables users to protect confidential and private data, protect themselves from data loss, malware and virus attacks as well as from lawsuits of unprotected systems.

Important Steps in Mobile App Security

Important steps in securing a mobile app include:

Secure Database

In order to secure a database, your storage must be fully encrypted and backed up with well defined data access to prevent any data breach.

Developers have to store user databases, credentials and other critical data in a secured place, no matter if it is a device or a cloud-based server.

Secure Source Code

Developers must provide a high level of security so that hackers cannot access your app’s code or decipher it with diverse methods like obfuscation or conceal code.

For example, Android has a Pro-Guard, a built-in feature making codes into confusing characters. Since Android is an open-source platform, it is more prone to cyber attacks and due to that reason, developers must ensure safe source code to prevent any possibility of alterations by cyber threats.

Secure Data Transmission

Developers must encrypt data in order to secure data transmission as it is extremely important for apps that transfer data like users’ private information or banking details. You should use secure channels via VPN tunnels, SSL, TLS or HTTPS communication.

If you do not encrypt data, the data transmission will be unsafe. If encryption-decryption algorithms are weak, they can be easily decoded by hackers leaving the app data in the open.

You should use strong cryptography to prevent snoopers, packet-sniffers and MITM attacks:

  • Input validation tests — they prevent malformed data from entering the app database. Such validations are already available in most mobile frameworks where you can customize it for an additional security layer to your app.
  • Data portability is the data that can be accessed across different platforms or services like the most popular one being ‘Social Login’ being a process of login to apps or sites with your Google, Facebook, Instagram or other login info.

These actions help developers to complete a thorough data protection and to add user-privacy and authentication from square one.

Sign-up procedures also become more user-friendly while improving user experience and satisfaction.

Perform Penetration Testing

Penetration testing is a process where a malware is imitated on your device to be able to search for any defects that can be exploited. Such testing is commonly used to improve web application firewalls (WAF).

Make sure to test your code for any sensitivity to injection attacks. Adapt and modify your WAF security policies and patch the bugs before launching your mobile app. Pen testing is independent from standard software testing but both of those are crucial to boost your app’s security.

Make it a custom to review and test the previously written code to test flaws and implement improvements.

Use Tokens for High-level Authentication

A token is a unit that securely transmits information about a user identity between the applications and websites. A security token authenticates a person’s identity electronically by storing some sort of personal information.

Mobile apps developers use tokens to monitor their user sessions efficiently and the same tokens can be either approved or withdrawn.

Usage of complex passwords should be applied — apps should be designed to accept only medium to strong passwords with alphanumeric characters and it must be renewed regularly, e.g. on each six months or so.

OTP (one-time PIN/password) is valid only for one login session on a computer or other devices. You can add it to make sign-ups more secure while adding a two-factor verifications also adds an additional layer or encryption making your app even more secure.

Other authentication methods can include fingerprint or retina scan — in the future, biometric access systems will probably get introduced to level up the security measures. Biometric testing can also be used for other purposes, like in workplace wellness system to set a standard of reference for employee health.

Tips for a Better Mobile App Security

Here are some of the common ways to build a safe and secure mobile app:

Write a Secure Code

The code is the most susceptible element of any mobile application and it can be exploited by hackers. Developers should write highly secured code for the apps and also perform code hardening and signing as a practice for developing the best quality code.

Encrypt the Data

Encryption is a process of taking plain text (message or email) and translating it into an unreadable format called ‘cipher text’. Encryption helps to protect confidentiality of digital data which is either stored on the computer or transmitted through the Internet. Once the intended recipient accesses the message, the information is translated back to its original format.

Encryption is said to be one of the most effective ways to save your data from being exploited in a malicious way. Even if your data gets stolen, the hackers will not be able to decipher it and will be useless to them, too.

Be Careful with Libraries

Usually, mobile apps need third-party libraries for code building. You should not trust the library your app is using as most of those are not so safe.

If you use diverse libraries, you should ALWAYS test the code as the flaws existing in the library can affect your code and allow hackers to use malicious code and crash the system.

Source: http://zesium.com/top-10-libraries-for-android-developers-in-2021/

Use Authorized API

You should ALWAYS use authorized API in your app code as it is recommended to have central authorization for the entire API to obtain maximum security in a mobile app development system.

API calls are usually protected by a simple API key and user credentials (often as an access token). Mobile apps are often less secure and since installed on a device, hackers can also install an app on a device they control in order to manipulate the app and find weaknesses.

That is why each API should require app-level authentication.

Use High-Level Authentication

Authentication mechanism is the most important part of mobile app security. Weak authentication processes are the top vulnerability in mobile apps.

User authentication must be considered as highly important from a security point of view. The common way of authentication is via passwords (medium to strong) which cannot be broken by hackers easily.

Conclusion

Having a mobile phone is a large part of our everyday lives and many underestimate the value a phone holds when it comes to the information it stores. Your phone contains much data from social media data to banking information.

When developing a mobile app, ensure that the app does not leave users susceptible to malicious attacks or privacy breaches.

Mobile app security protects the app and the data within — although users may install antivirus or anti malware software and use VPNs, if the app gets invaded by hackers or infected, users will still be open to cyber threats.

As a mobile app developer, always prioritize a robust level of protection and data privacy in the app for your users.

How Immersive Technology Can Boost Customer Experience

Immersive technology has been redefining the way businesses deliver their services and products to consumers. This revolution greatly enhanced customer experience in a way that no other technologies have been able to provide. Now, consumers can have realistic experiences by plunging into the virtual space before they actually buy a product or service.

How does this improve customer experience?

As you know, a good customer experience is all about making a customer happy while shopping for a product or service. This includes every step from inquiry to checking the products or services they want to avail, purchasing, and after service. All these aspects are touched by immersive technology while making the experience more interesting, accurate and effective thus helping customers to make the most of their hard-earned cash.

Immersive technologies are no longer a stranger to businesses today. In fact, Facebook recognized their power, which led them to the bold decision of buying the Oculus VR. In addition, Facebook and its acquired photo and video-sharing network, Instagram, have been using simple AR tricks using funny stickers in their camera apps. Lately, they incorporated simple Virtual Reality in their filter selections.

Source: virtualengineeringcentre.com

The result?

More and more people are getting hooked on both social media platforms. The FB and IG Stories, as well as their messaging apps, are gaining more traction among users because of all the fun filters and backgrounds incorporated in them. 

Businesses have also begun using the Stories feature to add a twist to their Instagram ads and engage their customers by adding interactive stickers. This only shows that FB and IG are putting immersive technologies into good use that’s bringing the platforms more and more profits.

But what is immersive technology?

Fully Immersive Virtual, Augmented, and Mixed Realities

Immersive technology can be classified into the following types:

  • Augmented reality (AR) adds computer-generated objects to the real world
  • Virtual reality (VR) changes what users see and experience by overlaying a computer-generated environment to the real world
  • Mixed Reality (MR) combines AR and VR in one experience

Immersive experiences can be built on these digital technologies.

Now that we’ve defined these immersive techniques, let’s find out about the current issues in managing customer experience that can be resolved using AR, VR, or a combination of both.

Source: elearningindustry.com

Current Challenges Faced by Businesses in Managing Customer Experience

The biggest issue faced by businesses worldwide is the limitation brought by the Covid pandemic. 

The effect is especially grim for those selling products compared to those that are offering services. The elimination of physical shopping as a way to preserve the health of both sellers and buyers has made skeptical shoppers more hesitant to buy. These shoppers are those who want to see and test products first before they give away their money. 

Meanwhile, this limitation lessened the opportunity for sellers to apply their “sales talks” to convince shoppers to buy from them.

How Immersive Technology can Resolve the Issue

Immersive technology is breaking the barriers and lifting the limitations brought by the lingering Covid pandemic. As people are advised to stay at home, businesses can use the different reality technologies to reach out to their customers and bring their offers virtually right in front of them, giving them a level of customer experience that’s similar to when they are shopping physically.

The use of Augmented Reality and Virtual Reality started a long time ago.

Nike has its Nike Fit app that leverages AR strategies to get the foot measurement of shoppers and give them a 360 view of what a shoe will look like on them even without physically visiting the Nike stores.  

IKEA has its IKEA Place that lets you place true-to-scale digital models of their furniture in real space. This allowed homeowners to check whether a couch or dining set will fit into their rooms without the tiring and time-consuming task of buying furniture and having it delivered only to find out that they don’t fit in their spaces.

The tourism and hospitality industries, before Covid happened, have been using VR to give travelers a realistic preview of hotel rooms as well as a virtual tour to the whole resort. This did not only help travelers decide on the right resort and room to book but also helped businesses convince more people to choose them over the others.

Now, all of these reality technologies are being improved as Covid’s likely here to stay. More and more businesses are realizing the importance of investing in AR and VR to give their customers the same shopping experience as pre-Covid.

People want to be safe at home but they also want to make sure that they are putting their money on the right product as they shop online. VR and AR give consumers a realistic way to check items online and feel confident about their purchase, like Sephora did with their Visual Artist. And when they do receive the exact product condition that they tested through VR and AR, customers will naturally feel happy and they’d return to the same shop for the other items they need.

Overall, Immersive technology is a creative way to deliver a spectacular shopping experience to consumers whether they are buying online or from a physical shop. Targeting the imagination of consumers gives them a unique experience that makes them thrilled and, later, convinced to purchase. So, the adoption of AR, VR, and MR in your business can open new opportunities to enhance customer experience and increase sales.

Implementing Immersive Technology in Your Business

Now that we’ve seen the impact of immersive technology on customer experience, let’s look into some ways on how you can use AR, VR, or MR to your company’s advantage.

1. Define the areas where you can integrate reality technologies

Before releasing any immersive technology efforts, businesses should first assess how AR, VR, or MR can be applied in their system. 

Check your products and how you can deliver them digitally to your customers. If you are selling food, you definitely cannot use AR and VR for your customers to have a free taste. But you can use these technologies to capture their interest, for instance, by using AR to show them how each food was prepared neatly in your kitchen or VR to tour them in your kitchen to touch their emotions and influence their decision.

2. Decide on how they can be shared with your customers

Now that you know how to use immersive technology to promote your product and make your customers happier when shopping, it’s time to decide on how people can access your AR or VR efforts.

Most businesses are now using apps that can be easily downloaded by customers on their smart devices to share the immersive experience. Like we cited above, Nike and IKEA are using apps based on AR to help their customers make a more informed decision even without visiting their stores.

Other ways can be through 360 tours and the use of AR or VR glasses, which may be more costly and impractical for both the seller and the consumer.

3. Collect data and convert it to Digital Data

All objects used in AR and VR are in their digital format. 

Finding a way to turn them into digital data and storing them in your app is the way to successfully impart an immersive experience to your customers. Nike has probably done 3D models of all their shoes in their different colors and sizes and those data are stored in the memory of the app. Businesses that want to use immersive technology will probably have to do the same.

4. Test the app and launch it

There’s nothing more frustrating than using an app that doesn’t work properly. 

Make sure that before launching it to the public, your app must be tested in real-life situations to know whether it is effective and to determine areas that should be improved. 

If you don’t, you are more likely to annoy your customers than make them happy.

Conclusion

Immersive technology has a big potential to help businesses improve their customer service so that their consumers can feel more satisfied with their shopping. With their power to connect businesses and consumers virtually, customer experience can be greatly improved. It may even serve as an interesting way for consumers and businesses to communicate like they are together in a single space when they are miles apart.

AR, VR, and MR are here to stay. Although they still cannot replace the experience that consumers can have in a brick-and-mortar store, they can at least do more than simply showing photos or videos to the consumers. 

Technology has also greatly revolutionized smartphones to transform ordinary photos of people and objects into seemingly flawless ones, which can also be done by the best photo editing software by manipulating and creating vectors in Illustrator or Corel. 

While their transformative capabilities are of great use to businesses, some buyers can be doubtful of the true quality of the product that they cannot decide on through photos. And this is just another aspect that immersive technology can resolve.

6 Reasons Why Application Maintenance is Essential for Your Product

Application maintenance is quite necessary for every product regardless of the business type. The developers sometimes avoid conducting application maintenance after the product release however, such maintenance is a major factor that comes in every place for the product. It particularly includes different processes from updating to stabilizing and securing the product’s application. 

Each product is necessarily required to go through the secured application maintenance process. If this is not initiated seriously, clients and companies could face a huge level of financial penalty while also suffering consequences of different maintenance problems. That is the reason why proper application maintenance is extremely important to rectify any issues that may be arising during the course of product functioning.

Bug Fixes

Many website entrepreneurs, businesses, or developers face bugs, so it is wise to regularly test and retest your product for defects or glitches. Both the application maintenance and development process encounter bugs in many ways but these bugs can occur due to several reasons, making the application maintenance process a difficult one. 

The bugs enter code during the application maintenance for the product – these specifically include last-minute changes, buggy third-party tools, and lack of version controls. Other areas of bug coding are unrealistic release schedules, miscommunications, and human mistakes.

Source: pinterest.com

The bugs usually occur in different varieties – some of them are seriously causing hindrance to application functionality while others frequently cause improper operating or unnoticed functions. Any kind of bugs can cause a huge problem for the entire product, so their elimination is quite necessary before raising a critical issue. 

App bugs can cause great disappointment and annoyance with users. The users’ inconvenience can be better avoided by eliminating different types of bugs on time, considering that most projects face bug elimination issues up to 5% to 10%. 

Security Patches/Updates

The application maintenance process involves an automatic update of the product system however, both apps and software are required to support updates through the manual process as well. The initiation of the update process can somewhat be a frustrating one, but clients and developers can still work on updates through an easy and simple process. 

The process of updating the product and its app enables acquiring more users while gaining ‘out-of-the-box’ features and an impressive brand at the same time. It is the main reason that the web application maintenance benefits provide routine service to the clients with the development of error-free applications and the development of the appealing product. These benefits further preserve usability, app data, progressive outcome and effective solutions. 

The important changes come during the course of the update although it mostly consists of security stability and web application performance. The systemic functioning of updates’ installation necessitates an effective working on the web application maintenance and its product review. It is good to know that the process of patching and updating software and apps is automatically resolved with the latest security problems.  

Third-Party API Updates

The application maintenance process involves a direct link with the third-party service and it mostly comprises Twitter, Facebook, and other social media sites. 

The API continues changing from the third-party service, meaning that it requires a timely update of the application maintenance. The newly developed service-based APIs should be used to update the entire product.

Source: pinterest.com

A slow working of the product occurs if the application maintenance is not carefully and timely updated with the right API system. This kind of maintenance is not regularly overseen where both old and newly developed APIs are continuously supported with the latest web application services. 

Most commonly, programmers initiate 8-16 hours to update the product with the application maintenance process and it is usually done to support a new development of third-party API making the overall product functions and systems functional, quicker and more accurate. 

Application Maintenance Scaling

A leading factor for the product’s application maintenance is its top-most scaling. It is similar to developing an MVP of the product where the app becomes highly popular with great expectations. The userbase of the product expands regularly, increasing the challenges for maintenance and support. However, there are many actions to introduce in order to resolve such maintenance issues. 

Facilitating New Functionality

Another aspect of application maintenance is facilitating a new functionality of the product and it is quite common, involving various features. It includes value-added work while facing tough rivals in terms of applications and products. It provides better product functioning due to the addition of new features during the application maintenance process. 

Amidst the course of application maintenance, development of new features comes as a leading factor. The clients and businesses are required to focus on the specific problems encountered during the product development process. The users’ feedback should be used for improving the overall functionality of the software or application. 

Monitoring:

The final step of the application maintenance of the product is its overall monitoring. Bugs cause a great issue for the product, making its functionality a serious issue. Bugs can crash apps and alter the API, forcing developers to focus attention on the application maintenance daily. 

A wise strategy to ensure robust monitoring of the product and its application maintenance is to hire an IT company that has experience in monitoring the product’s app. It can help developers to save time from everyday app maintenance issues while receiving direct alerts regarding the product’s development. Moreover, IT companies can develop the products in terms of updates, constant changes, web app development, and timely resolution of the app issues. 

The timely updates enable the users to enjoy stable functioning with the latest app or software versions. It finally saves companies from a financial penalty caused by poor application maintenance, thereby improving your brand with the latest app development trends. 

Conclusion

Maintaining the application requires the same amount of time as developing one – once you implement measures to maintain your product, you will be able to grow your application and acquire more users. 

Further and regular monitoring will enable you to upgrade your application easily and efficiently.
