Web Application Security Principles

Introduction to Web Application Security Principles

The CIA triad is a security model that organizations follow. It stands for confidentiality, integrity, and availability. These three forms the pillar of information security. The CIA triad also serves as the foundation for web application security principles.

Confidentiality is the primary core security principle that regulates access to information. This means that access to data is only for users which have permissions to it.

Integrity is the second core security principle. This ensures data is reliable, accurate, and consistent. There should be some restrictions on the modification of sensitive data.

Availability is the third core security principle. This one ensures data is available to all users with authority who need it.

The CIA triad has been the basis for the creation of web application security principles. When designing and creating applications, various security principles apply. If you’re looking for reference like a security design principles pdf, you can read one here.

You’ll know the importance of web application security principles later. You will also see the benefits of using SecureBox along the way.

Web Application Security Principles And Its Importance

OWASP is an international community that focuses on software security. OWASP stands for Open Web Application Security Project. They offer free tools, documentation, and guides on how to secure applications. Below are the web application security principles from OWASP:

Web Application Security Principles: Reduce The Attack Surface Area

If you add a feature to your application, it also adds up to the amount of security risk. This security principle is all about reducing these security risks. A real-world scenario would be the addition of a search field on your application.

This will provide the user with the ability to search for online help content. But this is also a chance for an attacker to inject malicious SQL commands on the search field. This would let them gain access to your system later.

Using a validation system is important to prevent this kind of threat. SecureBox watches over your application and network for any suspicious activity 24/7. You’ll get an alert when someone tries to input malicious commands on your application.

Web Application Security Principles: Establish Secure Defaults

There is a common security feature present in many applications. This is the login screen. Programmers call this an authentication system. The login screen is an important way of proving user identity. Once authentication is successful, the user gains access to your application. They can do things within their permission level or usage rights. SecureBox can alert you for login failures. This will protect your application from brute force cracking attacks.

Web Application Security Principles: Principle Of Least Privilege

It’s important to follow this principle if your application supports account creation. This means that accounts by default should have the least amount of user privileges. This includes user rights and permission to network resources.


Joe is a regular employee and thus would have default read and write permissions to files only. To gain a higher level of permission or usage right, Joe must ask permission from the IT people.

Access control is another term for this scenario. SecureBox can help you by alerting you with application usage reports. This contains a log of user activities about your application.

Web Application Security Principles: Principle Of Defense In Depth

An attacker has a little chance of being successful if there are a lot of security controls in place. It is important to note that SecureBox offers three layers of defense:

1. Prevention - SecureBox prevents threats from happening. It watches over your application, system, and network 24/7.

2. Detection - SecureBox detects known and unknown threats.

3. Removal and recovery - SecureBox will remove the threat. It also helps in the recovery of your application from the damage.

Every layer of defense that SecureBox offers has its own security controls as well. This makes it more difficult for cybercriminals to compromise your application.

Which design principle provides multiple layers of protection in SDLC? This principle of defense in depth is the answer to this question. This is one of the best web application security principles.

Web Application Security Principles: Fail In A Secure Manner

This is one of the many web application security principles where programmers fail. Handling application errors in a secure way is part of secure coding best practices. The error message should not disclose any system info to the attacker.

It’s important that programmers follow secure coding best practices. Following this makes their source code free from bugs, glitches, and vulnerabilities. This is one of the web application security principles a programmer must follow.

Web Application Security Principles: Don’t Trust Services

This principle tells that you shouldn’t trust third-party partners in an implicit way. You can never be too sure about their own sense of security. Using SecureBox will clear all your doubts. It’s important to know that SecureBox is an award-winning product. Many have tried and tested it already. It is a cloud-based program, so all the hardware and software are on the server side. You don’t have to do any technical stuff on your side. This is a very cost-effective security solution as well.

Web Application Security Principles: Separation Of Duties Or Roles

This security principle is about the separation of duties or roles. An administrator can install, uninstall or change application settings. But they aren’t allowed to use the application themselves. The normal user can use the application but can’t do the tasks of an administrator. SecureBox can provide you with different reports. It’s important to check if someone is acting outside their role or duty already.

Web Application Security Principles: Avoid Security Through Obscurity

Concealing your files or data is a weak security measure. Relying on a single form of security is not advisable as well. You should be implementing layers of security. It’s important to apply the principle of defense in depth in this scenario.

Verify user input to avoid the injection of harmful commands into your application. Always use an authentication system to verify user identities. Control the access each user has on your application. These are the most common web application security principles to keep in mind. You’ve seen what SecureBox can do for you in the previous principles.

Web Application Security Principles: Keep Your Code Simple

Programmers should write their code with security and simplicity in mind. It’s important to avoid writing “spaghetti code” or complex code. Writing source code that is simple is a good coding practice. This eliminates the difficulty when debugging it as well.

Web Application Security Principles: Fix Security Issues In A Right Way

A programmer writes a patch if they encounter a bug or glitch in their code. But their patch is one-sided most of the time. A programmer must be creating a solution to all other affected programs as well.

Any piece of info in the hands of an attacker is very dangerous. It’s important to be one step ahead of them. SecureBox doesn’t have a patch management system. But it can help you by generating application upgrade reports.
