Introduction to HTTP and HTTPS protocols

HTTP protocol stands for HyperText Transfer Protocol is responsible for transferring web information from servers to clients. Similar to HTTP is HTTPS protocol. S in the name of HTTPS stands for secure. Online checkout needs to use HTTPS protocol, you don’t want others to see transactions or intercept credit card information. If a website is poorly designed then it will use HTTP protocol in checkout rather than HTTPS, you should not use such a service, because your credit card number will be transferred in clear. Encryption and decryption of the information requires more system resources. Some companies decide to use HTTPS everywhere to simplify the infrastructure and to ensure that your credit card information is encrypted. If an Internet shop is not using HTTPS in checkout pages then you should not enter your credit card information. HTTPS is represented with a green color if your are using Chrome browser, or a lock if you are using Edge.

Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information.
