Web development has been evolving since the invention of the Internet. There was no concept of security and data encryption from hackers on web servers in the initial days. The majority of traffic stayed within the company only. Then came the idea of e-commerce or online shopping, where a user did not have to physically go to a store and buy a product/service. It led to a drastic increase in online users and the amount of data transferred. At this point, web developers realized that security is an essential aspect of web development. 

Several ways to hack into a website or steal user information are discovered. Injections (SQL, script, etc.), zero-day vulnerabilities, and social engineering are the most common methods. If a website is hacked, the hacker might steal all or some of these: 

What can be done to prevent such attacks? Web development security starts with the following techniques:    

1) Authentication and authorization

2) Stored data encryption

3) Proper coding

4) Use of firewalls and intrusion detection systems

5) Logging and monitoring

6) Password storage policy

7) Testing and vulnerability scanning

Security is constantly a work in progress and should be considered an essential part of web development from the very beginning. Using the above techniques can make your website more secure and protect your user data from hackers. 

In short, having security on your web development punch list means taking proactive measures to safeguard your website.
