Securing a website - how to do it?
Website security is becoming an important issue for all those who have their own website. Unfortunately, this topic is neglected by many website owners.
Few of them realize that a website needs to be secured in exactly the same way as the physical seat of the company. Therefore, mechanisms are needed that will allow both the website user and the owner to feel safe and protected against data leakage to the Internet.
This is especially important when more and more users are aware of the obligation to protect personal data, consumer rights and the rules of breaking website security.
Website security and personal data protection
The protection of personal data of customers and all users of the website is the responsibility of the website owner. The Personal Data Protection Act assumes that persons storing information about other users, such as: name, surname, address, etc., are obliged to protect it against disclosure to unauthorized persons, removal by an unauthorized person, processing contrary to the Act, as well as change, loss, damage. or destruction.
It therefore means that securing a website is one of the most important elements of its management and cannot be overlooked or treated as unnecessary.Adequate security for your website allows you to convince customers that your website is safe and takes your users' concerns seriously.
There are several ways to secure your website and customer data in your store. One of them is an SSL certificate that allows you to protect data sent by customers. Such a certificate encrypts the information sent by the buyer through the application form, for example. However, this is a solution that may unnecessarily burden the website server, so it is worth limiting its presence to such elements as: shopping cart, login, registration and order form.
Having a certificate is visible to the customer in the website's Internet address, where "https" and a padlock sign appear instead of "http". Aware of basic internet security, customers try to make purchases only in a store with such security, which is why having an SSL certificate is the basis.
Another element is the development of safety rules so that they do not fall into the hands of unauthorized persons. There is software that allows you to set up administrator accounts and set their access rights to specific parts of the website. It is worth using, especially if you need several people to operate the website.
Securing websites and company pages
In addition to the above-mentioned SSL certificate, a few other security measures will be useful when it comes to the security of corporate websites. First of all, it is good to bet on password-protected directories. It turns out that many of the commercial hosting companies allow this to happen. You only need to set the appropriate code for the directory created in PHP.
Another way to keep your website secure is to use secure scripts. Compared to CSSs made available on the Internet on the basis of OS, they do not have holes or other weaknesses that could be accessed by unauthorized users. It must be remembered that when we use add-ons downloaded from the network, we run the risk of being hacked, because in most cases their authors did not care about the safety of use. This rule also applies to updating scripts, even those downloaded from official websites. To make sure whether it is worth downloading a given add-on, you can check if it is on the list of "flawed" ones in the OS traffic forums.
You may also be tempted to use the appropriate attributes, and more precisely, define the access to the files. This is controlled via FTP and setting 644 for files and 755- for directories. Some files, the so-called catches need attributes to be read, written, and executed in 777 code.
Finally, you can set the server to newer versions of the PHP language - PHP5 or PHP7, which means that it will interpret files with the .php extension as PHP5 or PHP7.

Is my website vulnerable to attack?
Consider which sites are vulnerable to hackers. The answer is simple: all of them. Their victims can be both a person who rents a server or uses his own, and one who set up his website on the website platform. In this case, it is also irrelevant who made the website, because both clients of large companies and freelancers are equally vulnerable to data theft.
It is important to be aware of what could happen if the website was taken over by hackers. The following scenarios may occur: website traffic may be redirected to spammy sites, the server may be used to send spam, the website may be taken "hostage" and its restart may be dependent on the paid ransom, customer data may be stolen. Therefore, the security of the website used should assume this type of event. It should also be remembered that there have been no attacks related to damaging websites, as such action does not bring any material value to the attackers.
Fortunately, you can reduce the chance of an attack a bit by following a few general rules. It is important to secure your Wi-Fi connection. Otherwise, they are made available to each user, which allows for obtaining passwords and eavesdropping on the connection.
Using strong passwords, i.e. passwords that will be difficult to guess. Failure to do so may quickly hijack this code and make it easier to get the information you want. Difficult and unique passwords should be used to secure entry to such places as: administration panel, server, server administration panel and domain registrar, e-mail address to which the password reminder message is sent.
The same applies to the user's login. It must also be difficult to guess. It cannot be a full name or the word "admin" because they are too obvious. As with passwords, usernames should also be strong.
It's a good idea to protect the computer itself. Especially when there is a risk of infecting the so-called hardware. a keylogger, i.e. a program that reads what is typed on a computer keyboard and sends it to the person concerned. In order to protect the equipment, it is necessary to have a good antivirus program, install a firewall, and try to enter all passwords from the on-screen keyboard. It is also important not to download files from an unknown source.
