What is Mobile App Security? Mobile App Security Best Practices

Mobile App Security

Mobile app security refers to the processes used to defend a mobile app against fraudulent attacks like virus, hacking, or other criminal manipulations. In order to protect mobile apps from the numerous cyber dangers that a mobile device could offer as a result of the loaded apps, various technologies are deployed. Mobile app security measures how well an app is guarded against malware, phishing, and other serious hacker activities. An ideal illustration is Android, which is more prone to malware assaults, data breaches, and MITM attacks than the iOS platform, which is solely accessible to users of Apple products, because of its open foundation.

Mobile App Security Best Practices

Secure Code

Writing software that many users love demonstrates your skill, but protecting it from illegal and unwanted access is crucial and CANNOT be overlooked. Attackers can access a program through vulnerabilities, defects, and faults and threaten the company or the relevant authority. The study finds that over 11.6 M mobile devices are compromised due to malicious programs. According to the survey, 60% of Android devices swiftly contract an infection that occasionally transforms apps downloaded from phishing websites or unreliable third-party marketplaces. However, Windows laptops are the source of 40% of mobile malware.

Professional mobile app development company must design their products with mobile app security requirements in mind. Run a rigorous testing approach on each development stage and before deployment to avoid security threats and shield the application from attackers/fraudsters. Make your code adaptable and agile for simple patching, updating, and modification.

Secure Back-end

The back end is the software that runs on your server and houses the app’s database. Your back end needs to be equipped with security safeguards to prevent data exposure. The user data you’re keeping will be open to unauthorized access without the right security measures, such as firewalls and authentication requirements. Check your security settings frequently to ensure that your data is still protected and baking security directly into your code.

Data Encryption

Numerous consumers use numerous applications across various devices and operating systems. Therefore, you must ensure that no OS or device vulnerability exposes the data transferred over the application. Encrypting the data between applications is one way to accomplish this. Data is scrambled through encryption so that hackers are unable to decipher it. Data encryption can be done in two ways:

  • Symmetric encryption
  • Asymmetric encryption

Deta is encrypted and decrypted using the same security key in symmetric encryptions. Asymmetric encryption uses separate security keys for encryption and decryption at the same time. Secure coding is another recommended best practice for mobile app security.

Use Authorized APIs Unauthorized, poorly written APIs may unwittingly provide hackers access to systems that they could abuse severely. When performing API requests, for instance, programmers can reuse permission information by caching it locally. Additionally, making it simpler to access APIs makes life easier for coders. However, it also provides an opening for privilege escalation for attackers. For best security, experts advise central authorization of APIs.

Use Cryptographic Techniques

Even the most well-liked cryptographic algorithms, such as MD5 and SHA1, frequently fail to match the rising security standards. As a result, it’s critical to stay current on security algorithms and employ cutting-edge encryption techniques like AES with 512-bit encryption, 256-bit encryption, and SHA-256 for hashing wherever practical. To ensure impenetrable protection, you should also undertake manual penetration testing and threat modeling on your applications before they go online.

Use High-Level Authentication

Using passwords and other unique personal identifiers is referred to as authentication. Surprisingly, inadequate authentication is the cause of some of the largest security flaws. Use strong multifactor authentication to give your mobile devices and apps the best possible defense against security threats. You can use several methods for creating passwords advised by security professionals to maintain mobile app security, such as Dual-factor authentication; contemporary authentication techniques like fingerprint or retina scans.

Secure HTTPS

An HTTPS connection should be used for all communications between the app and the server. When using HTTP instead of HTTPS, the device is more susceptible to numerous rogue hotspots that can easily change the contents of HTTP traffic and cause the device’s apps to behave unpredictably. Many Android users frequently connect to multiple open WiFi networks in public places.

Use pen-testing

Even if automated tests can find the majority of security flaws before they are made public, there may still be openings that have gone undetected. It is worthwhile to hire a skilled pentester to test the application to reduce this risk. In order to identify weaknesses and potential attack vectors and safeguard the system from a genuine attack, this kind of ethical hacker tries to access the application. The pentester must be an outside specialist who is unrelated to the project.

Why secure your mobile apps?

Today, the majority of workers around the globe work from home, and some businesses engage independent contractors who use their laptops or computers to complete the company’s tasks. However, this strategy increases the risk of cyberattacks. The security of the company’s system and its clients’ privacy can be compromised with just one incident. In order to secure user privacy and data, developers must ensure that their apps have the newest security features available. Hackers typically target high-ranking corporate officers since they possess more valuable data.If done correctly, mobile app security enables users to safeguard sensitive information, safeguard themselves against data loss, malware, and virus attacks. And safeguard themselves from claims of vulnerable systems.


Today, mobile app security is a primary responsibility for professional mobile app development company to empower consumers by safeguarding sensitive information, malware, data loss, and other threats. Combined with the basic practices outlined in this blog. The market’s vast array of solutions for app security testing can help create a secure online environment for everyone.
