HTTPS is a protocol used to provide security over the Internet.
HTTPS is a way to encrypt information that you send between a browser and a web server. This protects your website’s users from “man-in-the-middle” attacks, where someone steals the information being sent to a website, like credit card information or logins. HTTPS guarantees to users that they're talking to the server they expect, and that nobody else can intercept or change the content they're seeing in transit.
2) Keep your computer updated
It may seem obvious, but ensuring you keep all software up to date is vital in keeping your site secure. Whether your website was built from scratch by your development team or software you may be running on your website such as a CMS or forum or you chose to create a DIY site on a third party turnkey platform. As a website owner it’s your responsibility to ensure that every piece of software that run in your website are up to date.
If your site uses third party plugins then keep track of their updates and make sure that these are updated on time as well. Often, many sites include plugins that fall into disuse over time. Clean out your website of any unused, old and non-updated plugins — they are sitting ducks for hackers to be used as a gateway to enter your site and wreak havoc on it.
3) Use security programs
Linux and other operating systems are the exceptions for this topic But Windows computer must have Security programs. So, let’s discuss about Windows Security programs for now. Security software has the ability to easily remove malware and also prevent a malware infection. This is one of the Best thing about security software.
For ideal and common security configuration use an Antivirus and an Anti-Malware at the same time. Use of two security programs at the same time is forbidden. But, that only goes for using two Antivirus or two Anti-Malware programs at once. Having only one Antivirus and one Anti-Malware is fine because the two of them detect different kinds of threats and are meant to work with each other. As for which ones to use, it comes down to personal preference. Malware Fox and Avast should make a good pair in general though.
Validation should always do both on the browser and server. The browser catch simple failures like mandatory fields that are empty and when enter text into numbers only field. You should make sure to check for these validation and deeper validation on server side as failing to do so could lead to malicious code or scripting code being inserted into the database or could cause undesirable results in your website.
5) Strong Passwords
Use of strong passwords is an effective way to limit brute force and dictionary attacks which are not completely eliminate. Use strong passwords for website server, admin, database passwords, email and online financial transactions. Make sure your password is a combination of symbols, upper and lower case characters, and alphanumeric characters to prevent brute force attacks make it at least 12 characters long.
To improve security, change your passwords regularly and use different passwords for your different website logins. Store user's password in encrypted form. This ensures that even if there is a security breach, attackers do not get their hands on actual user passwords.
