Ensuring mobile payment security is of utmost importance in today’s app-based commerce landscape. That’s because there are six billion smartphone users around the world, and more than 2 billion of them make mobile payments.
Statistics also show that less than half of financial mobile apps use proper security measures, and 77% of these apps have at least one critical security vulnerability. These numbers not only underscore the significance of prioritizing security while making payments through smartphones but also emphasize the urgent need for robust mobile e-commerce implementation and security measures.
In this article, we’ll discuss the best practices for both developers and end-users to ensure safe transactions in app-based commerce.
Common Security Risks Facing Mobile Payments
Before getting into further details on how to ensure mobile payment security, let’s discuss the common security risks that can jeopardize these transactions.
Malware, short for “malicious software,” refers to harmful programs that cybercriminals design to compromise your device’s security. They can infiltrate your mobile device through infected apps, suspicious downloads, or compromised websites.
Once on your device, they can steal sensitive information, such as your payment details, passwords, and personal data. Additionally, they can also monitor your actions and intercept your communications, which can lead to unauthorized transactions and data breaches.
2. Phishing Attacks
In simple words, phishing attacks are online scams. Cybercriminals impersonate trusted entities, such as banks or payment services, to gain your trust. They send you fake emails and messages (or even make phone calls) that appear to be from authentic sources.
However, these messages contain deceitful links or attachments, and when you click on them, they lead to malware installation or trick you into revealing confidential information.
Important Note: In the year 2022, over 50% of personal smartphones fell victim to phishing attacks. So, you need to be very careful while opening links through emails and messages.
3. Data Breaches
Hackers and cybercriminals use different tactics to breach databases of companies containing valuable user data, including payment information. Through these breaches, your payment card details, personal information, and transaction history could be exposed to hackers.
Once they have this data, they can impersonate you and make unauthorized transactions, leading to financial loss.
4. Lost or Stolen Device
If you lose your smartphone or it’s stolen, any payment information stored on the device could be accessed by whoever has it. Even if your device is locked with a PIN or password, hackers can find ways to break in. This can also lead to unauthorized payments or misuse of your payment methods.
5. Weak Passwords
Weak passwords are simple combinations of characters that are easily guessable or can be cracked with minimal effort. For instance, using “123456”, “password”, or even your name as your password falls under this category.
If your mobile payment account relies on such weak passwords, hackers can easily break them and gain access to your account. It can allow them to exploit your payment settings, initiate unauthorized transactions, or even gain entry to your interconnected financial accounts. That’s why it’s important to use strong passwords and store them securely.
6. Using Public Wi-Fi
Public Wi-Fi networks are convenient but come with risks. Cybercriminals can hack Wi-Fi hotspots by exploiting vulnerabilities in them to intercept data transmitted between your device and the network.
Best Practices to Ensure Mobile Payment Security
Here’s a list of the best practices that you can use to ensure safe mobile transactions in app-based commerce.
Secure Payment Gateways
To ensure the security of these transactions, make sure that you partner up with secure and trusted providers who also comply with strict industry standards and security regulations.
It’ll allow you to make sure that each mobile transaction on your app is executed safely.
Data protection regulations like CCPA (California Consumer Privacy Act), PSD2 (Payment Services Directive 2), and GDPR (General Data Protection Regulation) exist to safeguard user privacy. It’s essential to ensure compliance with the data protection and privacy regulations applicable to your app and region.
Not only will it improve your app’s security posture to carry out transactions safely but it’ll also allow you to manage user data responsibly and maintain legal standards for mobile payment operations.
Secure Development Practices
Incorporating secure coding practices means that your app is built with security in mind from the ground up. This involves employing techniques to prevent common vulnerabilities such as SQL injection or cross-site scripting.
You should also perform regular security audits and penetration testing, which includes reviewing the app’s code and infrastructure to identify any potential weaknesses.
This way, you’ll be able to address security issues to reduce the chances of attackers exploiting vulnerabilities.
End-to-end encryption is like a secure tunnel that protects user information as it travels between the user’s device and your server. It ensures data protection even if it’s intercepted because it’ll appear as random characters to unauthorized individuals.
The best ways to implement encryption include using HTTPS for data transmission and storing data in encrypted form using any of the modern encryption protocols.
Authentication and Authorization
Using strong authentication methods is critically important to make sure that only authorized users access payment features. You can use the following methods in your app for this purpose.
- Biometric Methods: Fingerprints or facial recognition are good examples of biometric methods. They can improve the security of your app, as they’re unique to each individual.
- Multi-factor Authentication: It requires users to provide two or more forms of verification, adding an extra layer of protection.
- Tokenization: It is a technique where sensitive data is replaced with random tokens. Even if an attacker gains access, the stolen tokens are essentially useless without the specific tokenization process used.
You can utilize the power of machine learning algorithms to identify unusual activities within your app that might indicate fraud. These automated systems learn from patterns of legitimate and fraudulent behavior and can flag potentially suspicious transactions.
Additionally, you can also place transaction limits and velocity checks and put a cap on the number of transactions that can be made within a certain timeframe. It’ll minimize the risk of large-scale fraudulent activities, as they usually involve a high volume of transactions in a short period.
Providing users with privacy controls empowers them to customize their experience according to their comfort level. So, you should allow them to choose the type of information they share with your app, the frequency of notifications, or the level of data retention.
Not only will it minimize the risk of security incidents, but it’ll also allow you to build trust and a stronger relationship with your user base.
Educate the End Users
Educating end users is essential to protect mobile payments from cyberattacks. It’ll help them make informed decisions and adopt responsible behaviors when conducting transactions through app-based commerce.
Therefore, we have created a list of best practices, which are basically for the end users to follow in order to ensure security while performing mobile app transactions.
1. Use Strong Authentication Protocols
One of the fundamental steps in securing your mobile payments is to protect your account from cybercriminals, and the best way to achieve that is to use strong and unique passwords.
A strong password typically includes a mix of uppercase and lowercase letters, numbers, and special characters. This complexity makes it difficult for attackers to guess or crack your password.
Additionally, it’s also important to use MFA (Multi-Factor Authentication) to add an extra layer of security. It asks you to enter your password and then provides a second piece of information, typically a code sent to you via text message or email.
This additional verification step reduces the risk of unauthorized access, as even if someone guesses your password, they won’t have the second factor needed to gain entry.
Lastly, you can use biometric verification as well, which involves using your unique physical features, such as fingerprints and facial recognition. It’ll help you ensure that only you can authorize transactions.
2. Avoid Public Wi-Fi Networks
As mentioned already, you should avoid using public Wi-Fi networks, as they increase the risk of falling victim to a cyberattack. Always use a secure private network to access the internet, especially when you need to make mobile payments.
However, if you don’t have access to a private network and it’s important to perform a transaction, make sure that you do it with an active VPN (Virtual Private Network) on your mobile. It’ll encrypt your data, making it almost impossible for hackers to intercept it.
3. Use Mobile Security Software
You can also install antivirus/anti-malware tools on your mobile to protect it from cyberattacks. They’ll scan your device, identify threats, and alert you in real-time to ensure your mobile payment data protection.
4. Turn off Bluetooth
Disabling Bluetooth when it’s not needed reduces your device’s attack surface. That’s because Bluetooth connections can be exploited by hackers to gain unauthorized access to your device. So, turning it off will limit the chances of unwanted access to your phone’s data.
5. Keep Apps and OS Updated
It’s important to keep your mobile’s OS and apps updated. That’s because updates usually come with security patches that address vulnerabilities discovered by developers or security researchers. It’ll also help you reduce the risk of exploitation by hackers.
6. Monitor and Review Transactions
You should make a habit of reviewing your payment history and statements regularly. It’ll allow you to find out if there are any signs of unusual or unauthorized activity. It’s also important to set up transaction alerts so that you can receive notifications about your mobile payments.
Cyberattacks on mobile apps and devices are on the rise. Therefore, it has become more important than ever for both developers and end users to take proactive measures to protect their sensitive information, financial transactions, and personal privacy.
We hope this guide has helped you understand how to perform safe transactions in app-based commerce and ensure mobile payment security. Lastly, don’t forget to stay up to date with the latest trends to protect yourself against evolving security threats.
