The Basics of Web Application Security

Web security is one of the most important components of any web-based business. Your website may be attacked from different locations at various levels of complexity and scale. Web application security tries to address this pressing issue. They can be used in web applications, websites, and web-based services like API.

Common web app security vulnerabilities

Your website can be attacked across multiple domains. Let us discuss some of them:

  • Cross-site scripting (XSS): In XSS the attacker can insert client-side script on your webpage to access some important information directly.

  • SQL Injection (SQL): In SQL the attacker attacks the working of a database. They can manipulate the queries and gain access to sensitive information.

  • Denial of services (DoS): In this, the attacker attacks the server and makes it overloaded. So the infected server cannot accept incoming services.

  • Cross-site request forgery (CSRF): In this type of attack, the attacker can trick you to enter a system through your authorization or authentication. He or she will be able to manipulate a system in your name.

  • Memory Corruption: In this case, a location in the memory is corrupted and modified. This results in unexpected behavior of the system.

  • Data Breach: Data breach is a collective term that refers to the release of confidential data.

How to protect your application?

There are various ways to protect your application from outside attackers. Although no protection is 100% secure, it can reduce the chances of the above-stated vulnerabilities. Your task is to remain up-to-date with the latest vulnerabilities and their cure.

You can use up-to-date encryption, proper authentication, regularly try to find new vulnerabilities and have a good software development team. Unfortunately, clever attackers can find vulnerabilities in the most secure web application. Your task is to make it as secure as possible.

Web application security deals with protection against application layers, DDoS and DNS Attack.

WAF – Web Application Security Firewall

A web application firewall can help you to protect your web application from application-layer attacks. In simple terms, it can help mitigate the risk of suspected HTTP traffic. It can protect you from attacks like SQL injection, cross-platform forgery, and cross-platform scripting.

DDoS Mitigation

One of the most common attacks on your web application can be a denial of services. In this case, your server is suspiciously loaded and it cannot accept any further requests. To mitigate this issue you will need a tool that can filter out legitimate requests from suspicious requests. If the request is suspicious it should not be allowed to reach the server.

DNS Security

DNS stands for Domain Name System. It is a personal database of the internet where the web browser can find its perfect web server. It is one of the most important tools for the entire web. Attackers can try to interfere with the working of the DNS.

So this was all about the basics of web application security. In this world of globalization, you should be careful with your web application security.
