You should know that the internet can be vulnerable. The security of a site is not to be taken lightly, it is something very complicated that requires in-depth technical knowledge in order to be able to identify vulnerabilities and put in place the necessary protective measures.
The security of a website is a crucial and essential issue for any administrator system concerned with preserving and protecting its site. Hackers are always looking for new vulnerabilities, but many security solutions are available to you, simpler and more sophisticated which will allow you to fight against hackers and hackers and protect your website.
Here are some simple tips in the form of a list of best practices that a professional must strictly apply to defend against automatic attacks and prevent those who target your website from entering it :
1. Make sure your website is updated
You must first ensure that the web server that hosts the site is correctly updated. If you hire a professional web host, that's their job. On the other hand, if you host your site yourself, it is up to you to make the necessary updates. Next, the site management system should also be up to date, along with any applications that play a role in site administration.
Some content management systems like WordPress make it easy to update automatically. As they also offer a very large amount of plugins, some of which may have glaring flaws. I advise you to find out about the quality and effectiveness of a plugin before installing it.
2. Ensure backup and protection
Never forget toperform regular backup for your website and also for all other information. Its frequency will depend on how often the site is updated, i.e. you will have to put a backup of your site every time you update it. You will realize the great value of this backup the day your site is hacked despite the precautions you have taken.
Finally, you must protect the access to the web server to avoid attempts to attack the site. For example, http authentication is one of the practices you can rely on to protect your web server.
3. Protect sensitive data
When you collect personal data, passwords, financial data, you have to ensure their security better than anything else. This is not only an obligation towards your users but also a legal constraint.
It is essential that you encrypt all data stored on your servers. The connection must also be encrypted (SSL) to prevent data from being intercepted during communication between the user and your site.
You must take special care of passwords to ensure more security, for this they must be encrypted before being stored.
As you also need to "hash" passwords with a suitable algorithm like " bcrypt " or " scrypt Which are difficult to be attacked, and avoid the usual MD5 and SHA1 which are more vulnerable.
4. Check the security of your web host
This is a more general security tip, it is very important that your host offers more recent versions of Apache, MySQL and PHP. Check with your web host or use a PHP file to get this crucial information.
