1. SSL Certificate and HTTPS Protocol
It is very important nowadays that your website has an SSL certificate with the HTTPS protocol.
Without HTTPS, a cybercriminal can change the information on your page for malicious purposes, for example, to steal information from your site visitors, such as login credentials (passwords). By using HTTPS, you are telling your visitors that they are interacting with a secure server, and it is also important to note that if you care about SEO, HTTPS is now a major ranking factor.
In fact, Google will tell visitors that a website is not secure and will even show them a warning if you are using regular HTTP instead of HTTPS.
SSL can be a low cost deal nowadays, as for unlimited subdomains pointing to the main domain requires cheap wildcard SSL. It provides single certificate management at a low price coupled with strong security. Without proper SSL, users will be faced with a security warning on the website.
SSL certificates, on the other hand, encrypt the communication between your web server and the user’s browser. While it won’t 100% protect your site against all malware attacks and infections, SSL is very important for protecting the data contained on your website and web server.
2. Update everything regularly
Don’t underestimate the importance of regularly updating your software and operating system. This applies to your web server’s operating system and any software running on your website, including forum software and CMS.
It is important to understand that no software is 100% perfect and secure, and that is why trusted software companies regularly update their software with security patches. Cybercriminals are quick to abuse security vulnerabilities that can be found in your software, and you don’t want to be compromised just because you forgot to update your operating system with a week-old security patch.

3. Use strong and unique passwords
Be sure to use a strong and unique password to authenticate your website and the administrator account of the web server and CMS.
We all know that complex and long passwords are recommended, but not everyone follows this advice.
Your password must be at least eight to ten characters long and include a mix of uppercase, lowercase, numbers, symbols, and spaces if allowed by the system. Also, make sure that the password is stored as encrypted values, and a one-way hashing algorithm is preferable.
Another important thing is to use a only password that you had not used in another account. M In the case of a credential stuffing attack, when one of your accounts is compromised, all your other accounts will also be compromised if you use the same password and username.
Last but not least, change your password regularly every 6 months to a year.
4. Back up your site regularly
Always be prepared for the worst. While we certainly don’t want to experience a situation where your website is compromised, in the worst case scenario we can minimize losses by making sure your website content is fully backed up.

Unless absolutely necessary, it is always best to restrict visitors from uploading files.
Any file could potentially contain a script that can exploit vulnerabilities in your website when it runs on your web server.
However, if a file needs to be uploaded, for example if you want your visitors to upload a photo of themselves and your product, then you need to ensure that the uploaded files are stored in a separate directory/database from the files. from your website. don’t forget about limit file types that can be uploaded to your site.

6. Set up your default CMS settings
Today, many cybercriminals rely on a botnet to launch automated attacks targeting websites with default CMS configurations.
Therefore, make sure to configure at least the following settings on your CMS to prevent these automated attacks:
- File/Folder Permissions
- Information Visibility
- user controls
- Comment Settings
Changing these should be pretty straightforward, so don’t forget to set them up as soon as possible and don’t make it easy for attackers to attack your site.
7. Use the right monitoring and protection solutions
Today, there are various tools and solutions that can help monitor the security of your website and even protect it from automated botnet attacks.
If your site is built with WordPress, there are several security plugins that you can use out of the box for this purpose. If not, check to see if your site’s CMS or website builder offers plugins, features, and security plugins, and there’s always the option of using third-party solutions like this.
