The mobile ecosystem is rich in features, with apps that can control everything in real-time, including your home’s heating and lighting. Mobile apps are continuously growing, and it’s critical that developers not just look for ways to create feature-rich apps, but also secure ones.
As data stored within the app might pave the route for attackers, mobile app security has swiftly become one of the top worries for many enterprises. They can use the information to get unauthorised access to sensitive data and possibly penetrate an organisation network.
To build secure apps, developers must be extra cautious and follow mobile app security best practices. Clearing the cache, employing encryption methods and tamper-detection mechanisms, and safeguarding local data are just a few examples.
At a Glance: Mobile App Security Issues
Improper session handling, flawed cryptography, inadvertent data leaking, and bad authorisation are all common difficulties with mobile app security. The most prevalent of these vulnerabilities is data leakage caused by the storing of app data in insecure areas.
The main issue is that data is stored in a location where other programmes can access it. When it comes to improper session management, this is a prevalent problem with e-commerce platforms. Long sessions are allowed by the makers of such apps in order to eliminate delays in the purchasing process.
7 Best Security Optimization Techniques In Mobile App Development
It is possible to protect your mobile application against such security dangers with the correct combination of tactics. In the next sections, we’ll go over all of the key ways of doing this.
The following is a list of some of the most important mobile app security best practices that developers should follow when creating and maintaining a mobile app:
Certificate pinning is a great approach to ensure that extremely sensitive data including credentials, users’ personally identifiable information (PII), mobile application logic code, confidential business data, and more are securely transmitted over the network.
Certificate pinning is a tried-and-true method of protecting against security flaws like compromised CAs and man-in-the-middle (MITM) attacks. Attackers can persuade consumers to install malicious material or a self-signed certificate on a mobile device, for example.
Traditional certificate validation (without certificate pinning) protects mobile apps from some types of MITM attacks, but not all of them.
Certificate pinning ensures that your mobile app only communicates with a known and trusted server using its own certificate. If a user instals a bad certificate, the mobile application can protect its network communication from being intercepted. This will prevent the attacker from accessing the user’s info.
Data Encryption/Secure Storage Options
Encryption is the process of transforming your data into an unreadable format for anyone who does not have access to the decryption key. It is an effective method of preventing data from being stolen or misused.
To keep data on your mobile app safe, make sure it’s protected from things like accidental deletion, unwanted access, and malware or infection.
What happens if the data you’ve saved in your app isn’t safe?
Using the file manager or various addresses in the mobile app, attackers can run an automated script or inject malicious malware to enter the local memory. They have access to private information, bank account information, credentials, social security numbers, and much more.
As a result, it’s critical that your data is securely safeguarded. You can encrypt your files so that they can only be read after a corresponding key has been deciphered.
Also, make sure that not only data storage is secured, but that all sensitive transactions within the mobile app are as well.
Libraries are one of the most regular targets for cyber-attacks. The danger increases in direct proportion to the length of your code.
To avoid security breaches, only utilise the most recent version of libraries with all available upgrades and modifications while developing your mobile app. This applies to proprietary, open-source, or a combination of the two types of code.
Keep Your API Keys Safe.
When retrieving data from various sources, API keys are frequently required. For example, they can be utilised for services like Google Maps navigation and the Google search engine.
API keys basically allow the system to determine whether or not a user is an authorised user of a specific service. It’s critical to keep these API keys safe from unwanted users who might try to get access to a mobile app’s internal systems and networks.
How can APIs be safely stored?
API keys should have a higher level of security and protection in this case, which is achievable because they are held on the server.
These keys can be securely maintained within the mobile app if the app does not have a server-side. In these circumstances, the keys are coded and encrypted, and only a restricted number of people have access to them.
Protect Your APIs
Unauthorized or poorly written APIs can accidentally allow an attacker access privileges, resulting in a data breach or loss. Make sure that all of your APIs require authentication and that authorization is strictly enforced.
How do you keep your APIs safe?
Implement the principle of least privilege (POLP) to ensure that only the data required to fulfil their duties is accessible to authorised users.
Experts also advise that validating all input data coming from the mobile device and the outside network is the best strategy to secure your mobile app from rogue users. Assume that anything could potentially be malicious code or cause harm to the mobile app.
Use Tamper-Detection Software
If someone tries to tamper with your mobile app’s code or insert dangerous data into it, you should employ tamper-detection tools that can instantly identify and set off alarms.
To help detect tampering in your mobile app, use digital signatures, checksums, and other validation methods. If an attacker attempted to modify the mobile app, the checksum would be validated, allowing the app to detect and block unauthorised execution.
While these solutions aren’t failsafe, they do significantly reduce the amount of time and effort required by an attacker to compromise the app.
Furthermore, administrators might be notified by mobile applications that identify tampering.
What can you do if you suspect tampering?
This is a highly subjective question that differs from one mobile app to the next. It’s a good idea to report these circumstances to the server so you can analyse the severity and scope of the problem and take appropriate action.
Manage Your Dependencies’ Vulnerabilities
Several security issues exist in mobile applications. If you don’t keep track of your components, attackers and other bad individuals can simply exploit them.
To mitigate app risks, the best method to defend your mobile app is to manage vulnerabilities in your dependencies and follow solid security rules and procedures.
The following are some of the most often used vulnerability databases:
- CVEDetails is a database of security concerns and vulnerabilities collected from a variety of sources. The severity and effect of each vulnerability are determined by the CVE score.
- The National Vulnerability Database (NVD) is the U. S. govt’s repository for numerous standards-based vulnerability management data.

Make sure you have adequate mitigation procedures in place to address any application security risks or vulnerabilities that may arise in your mobile app.
Create Safe Code
One of the most susceptible aspects of any mobile app is the code. Developers are frequently required to follow stringent and rapid deployment protocols, which can compromise a mobile app’s security.
Building a secure mobile app necessitates the use of secure code. In today’s market, speedy deployments are key, but it’s also critical to address security concerns early in the development process.
What is the best way to build secure code for a mobile app?
Regularly holding training for mobile developers to teach them precisely about secure code development is one of the greatest strategies to adopt mobile app security.
Furthermore, a secure software development lifecycle (SDLC), in which software is tested for multiple security vulnerabilities from the beginning of the development process, aids in the prompt identification and mitigation of security threats.
These are some of the best practices for mobile app security that developers should follow in order to provide vital endpoint protection to their apps. Mobile app security has been increasingly important in recent years, and with increased competition, businesses must not only focus on creating a user-friendly UI but also on ensuring that the mobile app is secure.
Regardless of who your mobile app is intended for, whether it’s an internal app for internal tasks or a customer-facing app, it must be created in a safe manner to avoid unscrupulous users from conducting cybersecurity attacks.
