5 Essential Hacks to Safeguard Your Mobile Apps

Building a secure mobile app is not just a task; it’s a necessity in today’s digital-first world. A small vulnerability can open doors for hackers, putting your users and business at risk. So, if you’re serious about keeping your mobile apps safe, it’s time to take action. Here are 5 essential hacks, practical and effective ways to secure your application.

5 Essential Hacks Understanding Mobile App Security Threats

Common threats in the digital space before one starts considering solutions include mobile app security flaws that occur when important areas are not paid much attention during development.

• Data breaches: Users’ sensitive information gets leaked.
• Insecure Servers: An attacker can easily hack an insecure server.
• Malicious Code Injection: Hackers inject malicious code into the app’s code.
• Weak Authentication: Users are vulnerable to account takeover with no multi-factor authentication.
• Unsecure Data Storage: The stored data remains unencrypted and can thus easily accessed.

These can be known risks, but the way in which you defend your app from those risks is quite another issue.

1. Encrypt the Data on External Storage

Some applications even store their users’ data in external storage, but with the proviso that external storage may not always be safe. In case it is unsecured, any user having access to the device will easily retrieve it.

To avoid this, the protocol to be used should be the Advanced Encryption Standard (AES). It encrypts the data such that even if accessed by some person, they cannot read it or misuse it. This is similar to putting your data in a vault; without the key, it is useless to intruders.

The use of encryption is a must, especially when keeping private, financial, or health data. Spending a minute in encrypting might save you from big breaches of your data.

2. Internal Storage is Your Best Bet

Internal storage is much safer, especially when it comes to storage of sensitive information. Data placed inside internal directories cannot be reached by other apps; it’s safe because, unlike external storage, its data is safeguarded by the system.

In case of Android, data will be private to the application in case the MODE_PRIVATE is specified. Hence, no other application installed on the device can sneak into this data and steal it. For iOS, secure directories such as Keychain handle sensitive credentials safely.

The idea here is to make it virtually impossible for the malcontents to find, or alter any of your data.

3. Switch to HTTPS for Secure Communication

Still on HTTP? Well, time to let go. HTTP allows an attacker to intercept the communication between the app and the server because your data are left open and unencrypted.

Switching to HTTPS, therefore encrypts all the data transfers keeping the details of the users safe from pry eyes. It’s almost like sending your data in a locked briefcase instead of that wide-open envelope.

In today’s world, with public Wi-Fi networks found on nearly every corner, HTTPS is a no-compromise issue-it protects your app from man-in-the-middle attacks and helps ensure users feel safe interacting with your platform.

4. Use Keychain to Store Sensitive Credentials

Passwords and sensitive credentials can be pretty tricky to handle. If not stored properly, they are the easiest targets for hackers. This is where Keychain comes in: a secure storage system managed by the operating system of the device.

Especially, keychain is useful to store:

• User passwords
• API keys
• Authentications tokens

It is special because of encryption and isolation in that no other app is permitted to access the data so it reduces the security risk. Sensitive information also can be kept in Caches if it is not often accessed for data.

5. Ask Not for What You Do Not Need

Excessive data collection is annoying to the user, and also increases security risks. Hackers can’t steal what does not exist, so reduce the data you collect.

If your app collects sensitive information, ensure that access is controlled through native frameworks. This way, using secure authentication and authorization systems will make it much harder for attackers to duplicate or steal data. In other words, the less data you gather, the safer your app becomes.

Final Thoughts

These 5 essential hacks are practical solutions that can make your mobile application much safer. Mobile app security is not something you do once and never touch again. It’s always a process of determining risks, getting rid of vulnerabilities, and always keeping ahead of cybercrooks. You’ll be more effective at not having a breach if you implement encryption, secure storage, and HTTPS.

If designing a hack-proof app seems too overwhelming, do not worry. Experts can be of help when designing secure apps for the trust of your users. In fact, a safe app is not only good for your users but also for your business.
