Modern web development field is competitive, fast growing and it often requires lots of quick decisions, in-depth knowledge and ability to adapt to new environment. Businesses that have software as the source of their profits need faster production.
But as the IT is growing dramatically, development is becoming more complex – now you have to be a universal warrior who can create apps for any devices; they must be able to integrate with other services and withstand hacker attacks. Seems like a task with the star, right?
Unfortunately, when you have so many things to remember about, something would always fall short. Taking into consideration the fact that 99% of apps have significant vulnerabilities, it seems that developers often forget about the security.
We cannot mention each and every step you should take to ensure your app is secure – there is too much to keep in mind here. But read along to discover the most crucial steps for better app security.
One of the most common troubles developers provoke themselves is keeping the sensitive users’ information secure and failing to protect it the right way. How can you fix it? Simple – choose the data wisely.
When it comes to building the app, sit back and select what data you really need to store. Most of the time, you can omit storing credit card information or personal data – when the third party gets this information, you and your customers will be in trouble.
Once you know you absolutely must keep some users data, be sure you are not keeping it as plain text in your database. Encrypt it to ensure no one would make the use of users passwords and personal information.
If the connection uses a cookie, data has to be secured properly. It is way too easy for hackers to steal user’s ID session and get the complete access in no time. This is a common mistake even for experienced developers, so be sure to fix it.
If you don’t want to lose all your data or have SQL injection, filter and sanitize user injection. It should never have direct contact with the database. One missed input in the app, and you will get your company to the news not in the best way possible.
Developers should do two main things with software.
The first one – patch and update all the software you use for development. Hackers can easily get into your files through outdated or insecure programs, so don’t give them a chance.
The second software-related tip is to disable all the programs you don’t need. The more services or pieces of software there are, the more additional paths for hackers exist. If you are not using something on a daily basis, you might forget about updating it and your whole system would become vulnerable.
Experienced developers should never mistake client-side validation for the best security measure. It works to ensure users do not forget to fill out a field or mistype their password. But if you want to keep users from injecting their own codes into your project, be sure to have server-side validation.
Most of the time, the biggest threat for the app is not some mysterious hacker. As they say, eight times out of ten the greatest threat is sitting there staring at the screen. Try not to give end users too many privileges – this will keep your application safe and secure.
The Principle of Least Privilege would both protect users and the system in case any troubles occur.
