The website you built on your own for your business or personal use can also be hacked. So be aware of the threat that hackers posses.
Some advice tips to protect your website from hacking disasters.

Software Updates

Make sure you keep all your software and plugins up to date. If you use some third-party plugins on your site make sure you update the plugins. Keep track of their updates and ensure they are updated on time because software update avoids your computer from being hacked.

Use HTTPS

Hyper Text Transfer Protocol Secure (HTTPS) is a protected communication which transfers sensitive information between the web server and website. The website is usually on HTTP in most cases, but HTTPS is a necessity for all online transactions.

Use Strong Password

It is crucial to use a complex password always on your server and your website. Do not use the same credentials for all of your different website logins. Change the password frequently to keep your site secure, make sure your password is a combination of alphanumeric, symbols, lower and upper case with at least 12 characters long.

Use Web Application Firewall (WAF)

The web application firewall (WAF) securely transfers every bit of data from your website server and your computer to protect from harmful threats. Most of the WAF is cloud-based on a monthly subscription fee, once the firewall is installed it blocks all hacking attempts and filters unwanted traffic.

Hide Admin Page

You must hide the admin page so it won’t be indexed by search engine instead, you can use “Robots_txt” file. It will be harder for the hackers to find the admin page.

Database Server

Only Use Trusted Devices

For those who have a habit to log in to any public device should avoid it for security purpose. You must use only trusted devices such as a Personal computer in order to avoid being hacked.

Use SSL

Use an encrypted SSL protocol to transfer users personal information between the website and your database. This will prevent the information from being read in transit and accessed without the proper authority.

Back-up frequently

Anything can happen anytime, take a backup in order to avoid losing data. Every time a user saves a file it should automatically back up to multiple locations. Backing up once a day means that you lose that day’s data when your hard drive fails.
