It is safe to say that everyone in the world has become a potential customer of an online business or website. This is a great thing, but it is not all roses. Because of this, hackers are also targeting more e-commerce businesses.

E-commerce businesses have to be very much careful about the security of their websites because if they get hacked then they can lose their reputation and they can lose their customers which is why it’s important to perform security testing. In this blog post, what security testing for e-commerce websites is and why it is important.

What is Security Testing for E-Commerce websites?

Security testing is the process of testing a system or application to discover vulnerabilities that an attacker may exploit. Security testing is often conducted by a special team of security testers who are independent of the development process. 

The main aim of security testing is to identify areas where there are vulnerabilities in the system or application and fix them. The art of security testing is to find vulnerabilities without breaking the system or application. 

Security Testing for E-Commerce Websites is a process of testing the security of an E-Commerce website and its components like shopping cart, payment gateway, etc. which are usually attacked by hackers and malicious users.

Why is Security Testing for E-Commerce websites important?

E-commerce stores don’t have the luxury of being small businesses with a limited number of users. When it comes to online shopping, the sky’s the limit. With the convenience of online shopping, the appeal of e-commerce sites is undeniable and it’s a booming industry. But with the boom comes more vulnerabilities that need to be considered. 

With the many new features, however, come new security risks that need to be accounted for, especially when you’re dealing with private data like credit card information and customer addresses.

Security testing is one of the most crucial elements in e-commerce websites because of the confidential data and sensitive information that is handled. An e-commerce website is bound to face security threats with its high profile, data, and information. 

E-commerce scams are a real thing that’s being dealt with. These scams are very harmful and are costing a lot of money to online stores. There are a lot of different ways that e-commerce websites can be hacked: 

  • Hacking directly into the database
  • Exploiting coupon code vulnerabilities

Why do hackers target E-Commerce businesses?

Over the last few years, a large number of e-commerce businesses have been hacked. This is because of the data that they store on their website. E-commerce businesses store a lot of sensitive user data such as:

  • User information
  • Credit card data 
  • Passwords
  • Order details 
  • Address details and much more. 

When this data falls into the wrong hands, it can be used for identity theft. This leaves you with a ton of problems and you may also be liable to pay for any damage that is caused by the stolen information. 

Aside from the monetary value of the data, there are other reasons why e-commerce businesses are targeted. Sometimes, hackers target e-commerce businesses to vandalize them.

4 Best Practices to avoid security vulnerabilities

E-Commerce websites must be tested for vulnerabilities regularly as they are under the constant threat of attacks and breaches. Besides this, the implementation of certain measures can greatly help avoid certain vulnerabilities. 

Let’s understand some of these important practices to avoid security vulnerabilities: 

1. Use Secure Protocols

The most common security vulnerabilities are caused by the use of insecure protocols. Most of the time, it’s because the developers don’t pay attention to the security of the connection and they don’t know how to check if the connection has been encrypted. The use of secure protocols (such as TLS 1.3) is a good practice that should be followed on all e-commerce websites. 

2. Use Strong Passwords and Encryption 

The next common security vulnerability is caused by the use of weak passwords. It’s a good practice to use strong passwords and to ensure they are encrypted. The use of strong passwords and encryption technology is something that should be on the checklist of every e-commerce website. 

3. Securing Payment Gateway

The payment gateway is the heart of the e-commerce website. It is the most crucial component of the e-commerce business. If your payment gateway is down or if someone gains access to it then it is the same as letting the thieves into your house. 

You wouldn’t want that to happen, would you? It is one of the most sensitive parts of the e-commerce website and it should be secured at all costs. As it is the gateway that handles the transaction between the customer and the store owner.

4. Deploying Firewall

Firewalls are a standard in the field of information security, and they’re a great way to protect your network from a whole host of threats. But what exactly is a firewall? A firewall is a piece of software that sits between your network and the Internet, that stops unauthorized traffic from entering your network. 

Firewalls can stop everything from simple DoS or an SQL injection attack to sophisticated malware that can steal data and send it back to a hacker.
