Software is increasingly becoming an integral part of modern businesses. Growing demand for software means developers have to work incredibly hard to keep pace. Businesses need faster application delivery as web development becomes more and more complicated. For example, with tight deadlines, web developers need to build apps that can scale to any device, integrate with other services, and be ported to any platform. On top of that, they need to build applications that can withstand increasingly complex attacks.
The problem is, with increasing demand and changing requirements, web developers often struggle to keep pace. Some aspects of development tend to be overlooked, and security is a major culprit. As security becomes more and more an important part of development, there are some basic rules that most web developers do not follow. security principles. Therefore, there are many applications with serious security holes. This article aims to outline important safety guidelines that every web developer should follow.
1. Implement security tests
As hackers invent new techniques every day, security testing is necessary to improve the security of your web application. The goal of web application security testing is to determine how vulnerable an application can be and whether its resources and data are protected from potential attacks.

2. Know what you need to protect
An important security principle that every web developer should follow is to store only the data they need. To determine what data you should store, consider how badly it could harm the business or the customer if the data were compromised. There is really no need to store sensitive customer data like their credit card numbers and addresses.
3. Encrypt sensitive user data
If you need to store sensitive information in your database, make sure it is encrypted. Storing unencrypted data in your database can easily put you and your business in hot water. You don’t want to lose sensitive customer data because you’ve kept it in plain text in your database. Encryption of sensitive data is even more crucial in shared hosting or large enterprise environments because not everyone with access to the data can be trusted not to exploit it.
4. Use a VPN
A reliable VPN connection can help protect your customers’ data as well as your assets. If a hacker gets hold of your IP address, they can easily hack your device or install malware. This is a big risk for web developers because they have a lot of assets to protect, including custom designs, applications, and frameworks among others. If they fall into the wrong hands, they can compromise the integrity of the application you create. A good VPN provides advanced encryption protocols to protect against this.
Additionally, depending on the website you are working on, you may gain access to critical customer data, which can be devastating if compromised. Diagrams, financials, patent information, and more can fall into the wrong hands if you’re not careful about your safety. Hiding your IP using a VPN eliminates the risk that this data faces.
5. Keep your software up to date
When trying to access your database, a cybercriminal will always try to exploit the path with the least resistance. In most cases, the path of least resistance is in insecurity and outdated software. To minimize the risk of being hacked, be sure to properly patch and update your app.
Another important thing that you need to do is deactivate unused software. It is common to find companies with software related to their systems that are not in use. Left unchecked, unused software provides an easy path for hackers.
6. Apply the principle of least privilege
Sometimes the external attackers aren’t the biggest threat to your data. This could be an uninformed end user with multiple system privileges. By reducing user privileges, you minimize the risk of security errors from inexperienced end users.
In every computer system or web application, it is prudent to give users only the privileges that they really need, rather than giving all users the same level of access. The principle of least privilege keeps your system more secure by eliminating the risk of abuse by unqualified users. It also removes non-privileged users from liability for breaches.
7. Use server-side and client-side validation
For added security, be sure to perform both server-side and client-side validation. Server-side validation helps prevent malicious input, such as someone implanting their code into your database. Client-side validation helps prevent user errors such as forgetting a field or entering data incorrectly.
8. Clean up user input
There should never be direct communication between user input and the database. It should be cleaned up and validated to improve data integrity and prevent common attacks such as SQL injection.
The massive expansion of the Internet depends heavily on web development and design. Web developers and designers manage a lot of sensitive customer data, and these are major targets for cybercriminals. The above security tips can prevent your web application from being an easy target for hackers.
