Why is Security Testing for E-Commerce websites important?

E-commerce stores don’t have the luxury of being a small business 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.

Security testing is the most crucial element 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. 

If a website is not secured with the latest security measures, then the website is vulnerable to malware and spyware, unauthorized access, data theft, and many more security threats. 

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:

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

Security testing for e-commerce websites is an important task. Let’s understand some of the 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 is a good practice that should be followed in 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 attacks to sophisticated malware that can steal data and send it back to a hacker. Firewalls are one of the most important pieces of technology in the field of information security, and the best way to find out how effective your firewall is to put it to the test.
