You can do a lot of things using your smartphone. One of which would be to buy stuff online. Doing so would require users to input sensitive information and an unsecured app can compromise this data and it would fall on the wrongs hands.

With that being said, here are some of the biggest risks to android app development app  security:

Lack or Unsecured Server Side Controls

Whenever a user does some online banking, for example, they would have to use an application for that. The communication between the user’s phone and the server that is responsible for the online capabilities of the application would have to be secure. Otherwise, the data could be intercepted by the malicious attackers and can be used for personal gain.

The reason why this is still prevalent in this day and age is due mostly to budget constraints. Since security is now a major concern, you have to hire a dedicated person that will handle such tasks for you. Never skimp on your app security.

Not Using Encryption

App developers who are lazy usually depend on the client side to store data. In other words, the information that is deemed to be sensitive is just placed inside the user’s phone.

There is no problem with it, per se. However, it does become a problem if the data is not encrypted. Once the phone gets stolen or lost, the person who can get a hold of it would be able to extract that information and can be used for identity theft and other nefarious purposes.

Therefore, it would be wise to implement an encryption mechanism so that the data that is stored on the client’s side would be somewhat secure.

Data Leakage

The term refers to sensitive data that is placed in an unsecured location in the person’s phone. When there is a loophole in the operating system, an attacker could exploit this to gain access to the sensitive data that is put inside the phone. Therefore, it is a must that you, at least, put the data in a secure location that is not readily accessible by anyone.

Poor Authentication Procedures

When it comes to security, one way to make your data secure is to have an authorization or authentication protocol so that the data can only be accessed by the owner. Thankfully, it can be done now by using the fingerprint scanner and the newly implemented facial recognition features of the smartphone itself.

You must always implement a solid authentication procedure so that sensitive data will not fall on the wrong hands.

Broken Cryptography

The term just refers to a common security vulnerability in which a hacker can exploit a vulnerability to gain access to information that is stored from within the client’s device. This is mostly due to complete dependence on only one security protocol.

It is mandatory that you implement two or more security protocols to ensure that if one vulnerability gets exploited, there are other measures to counter the hacker’s advances.

Client Side Injection

This is where a malicious code is executed on the client’s mobile phone. Once that is done, a code will then be released and it could do a lot of bad things like steal your information, among many others.

The easiest way to combat this would be to prevent application vulnerability by identifying the sources of input; making sure that the supplied data (by the user) is subject to input validation, thus not allowing any code injection to take place
