Website security is not a one-time setup after launch, but an ongoing process. A website may work for years without visible problems, but an outdated CMS, a vulnerable plugin, a weak password or the lack of backups can at any moment lead to a hack, data loss, email blocking or infected pages containing malicious code.
Why website security is important
Many website owners start thinking about security only after a problem has already happened: the website stops opening, unwanted ads appear on pages, the browser starts showing warnings, email stops being sent or the hosting provider temporarily blocks the website because of malicious activity.
However, a website hack usually does not happen “just because”. In most cases, the reason is an outdated CMS, theme or plugin, weak passwords, an infected administrator’s computer, exposed technical files, incorrect file permissions or lack of control over who accessed the website and when.
If the website is used for sales, inquiries or communication with customers, even one day of downtime can mean lost orders, damaged reputation and reduced trust. That is why security should be handled before a problem appears, not after the website has already been hacked.
Who should be responsible for website maintenance
If a company has its own website, it is important to define who is responsible for its technical condition. This may be an in-house system administrator, a developer, a web studio or an external company that maintains the website after launch.
A business owner does not have to understand every technical detail personally. But there should be a person or contractor who understands what the website runs on, where it is hosted, how backups are created, which versions of PHP, CMS and modules are used, which access credentials are active and what should be done in case of an incident.
Problems often appear when a website was “just created” some time ago, but no one maintains it after launch. The CMS is not updated, plugins remain outdated for years, backups are not checked, and access credentials have been shared with different people without changing passwords later.
A website is not a static picture. It is software that requires maintenance. Just like a computer or a server, it needs to be updated, checked and protected.
CMS, modules and security updates
Many websites run on popular CMS platforms such as WordPress, Joomla, OpenCart, Drupal, MODX or other systems. This is convenient because such systems provide ready-made functionality, templates, plugins and a large community. But popularity also has a downside: attackers actively search for vulnerabilities in widely used CMS platforms, themes and extensions.
If a critical vulnerability is found in a CMS, plugin or theme, developers usually release an update. But it is the website owner or the responsible technical specialist who must install that update. If a website is not updated for years, it gradually becomes an easy target for automated attacks.
It is important to update not only the CMS itself, but also all installed modules, plugins, themes, libraries and the server environment. An outdated PHP version or an unsupported plugin can be just as dangerous as an old version of the CMS itself.
At the same time, updates should be performed carefully: first create a backup, check compatibility and, for important websites, test changes on a copy of the website. However, postponing critical updates for months is also dangerous.
Why choosing a responsible developer matters
The desire to save money on website development is understandable. But an overly cheap solution often has a hidden cost. The website may be assembled from random templates, outdated plugins, poor-quality code or without any documentation. After launch, such a developer may disappear, and another specialist will have to fix the problems.
A responsible developer does more than “make a website”. They explain what the website runs on, which modules are installed, which access credentials are needed, how updates should be performed, where backups are stored and who will be responsible for support after launch.
It is especially important that the developer does not leave unsafe solutions in the code: test scripts, exposed configuration files, temporary passwords, unsafe forms without data validation or hidden user accounts.
If the website is important for the business, future technical support should be planned from the beginning. This may be a maintenance agreement, periodic security audit or an arrangement with the developer for updates and response to critical issues.
Website access, FTP, SFTP and passwords
One of the most common causes of website problems is uncontrolled sharing of access credentials. Passwords are sent through messengers, stored in plain text files, shared with multiple contractors and not changed after the work is finished.
If a developer, administrator or another specialist needs access to the website, it is better to create a separate account with the required level of permissions. After the work is completed, this access should be disabled or the password should be changed.
For working with website files, it is better to use more secure access methods such as SFTP or SSH instead of plain FTP, if they are available on the hosting service. It is also not recommended to use the same password for hosting, email, CMS admin panel and other services.
For admin panels, hosting accounts, email services and other important accounts, two-factor authentication should be enabled wherever possible. This significantly reduces the risk of unauthorized login even if the password is leaked.
Security of computers used to manage the website
It is necessary to protect not only the website itself, but also the computers used to access it. If a developer’s, administrator’s or website owner’s computer is infected with malicious software, it may steal passwords for FTP, hosting, email or the website admin panel.
That is why it is important to use an up-to-date operating system, antivirus protection, an updated browser, a password manager and avoid storing access credentials in random text files or old FTP clients without proper protection.
You should also avoid opening suspicious links from emails, messengers or messages from unknown senders. Phishing pages often imitate login pages for email, hosting or popular services in order to steal usernames and passwords.
Consequences of a website hack
The consequences of a website hack can be different. Sometimes the website simply stops working. In other cases, attackers add unwanted ads, hidden links, phishing pages, malicious scripts or files used for sending spam.
A hacked website may be used for:
- sending spam;
- hosting phishing pages;
- spreading malicious code;
- redirecting visitors to third-party websites;
- creating hidden administrator accounts;
- placing unwanted SEO links;
- stealing user data or form submissions.
As a result, the website may be blocked by the hosting provider, email messages may start going to spam, browsers may show warnings, and search engines may temporarily reduce trust in the website or mark it as unsafe.
Recovering after a hack often takes more time and money than regular prevention: updates, backups, access control and basic monitoring.
Backups and monitoring
Backups are one of the most important elements of website security. Even if the website was hacked, damaged after an update or important files were accidentally deleted, having an up-to-date backup allows the website to be restored much faster.
But it is important not only to create backups, but also to periodically check whether they can actually be restored. A backup that has never been tested may turn out to be incomplete or outdated exactly when it is needed most.
It is also useful to monitor website logs, errors, unusual files, suspicious logins to the admin panel, newly created users and notifications from the hosting provider or search engines.
For popular CMS platforms, additional security tools can be used: login attempt limits, two-factor authentication, a web firewall, file change monitoring and malware scanning.
Short website security checklist
- Update the CMS, plugins, themes and server environment.
- Remove unused plugins, themes, test files and old website copies.
- Use strong unique passwords for every service.
- Enable two-factor authentication wherever possible.
- Do not share main access credentials unless necessary.
- Create separate accounts for developers and contractors.
- After the work is finished, change passwords or revoke access.
- Use SFTP or SSH instead of plain FTP, if available.
- Create regular backups of the website and database.
- Check whether the website can be restored from a backup.
- Pay attention to notifications from the hosting provider and search engines.
- Do not open suspicious links and do not enter passwords on unknown pages.
Frequently asked questions
Do I need to update the website if it already works?
Yes. If the website opens without errors, it does not mean that it is secure. An outdated CMS, theme or plugin may contain known vulnerabilities that are already being used by automated bots for attacks.
Who should be responsible for website security?
Responsibility should be defined in advance. It may be an in-house administrator, a developer, a web studio or a company that maintains the website. The main thing is to clearly understand who performs updates, checks backups and responds to technical issues.
Is an SSL certificate enough for website security?
No. An SSL certificate protects data transfer between the browser and the website, but it does not protect the website from CMS vulnerabilities, weak passwords, infected files or unsafe plugins. SSL is an important part of security, but not the only protection.
What should I do if the website has already been hacked?
You should temporarily restrict access to the website, save logs for analysis, check files and the database, remove malicious code, update the CMS and plugins, change all passwords and restore the website from a clean backup if one is available.
Why should I not share one password with all contractors?
If everyone uses the same password, it is impossible to understand who performed specific actions on the website. In addition, after ending cooperation with one contractor, you would have to change access credentials for everyone. It is better to create separate accounts with the necessary permissions.
Do I need backups if the hosting is stable?
Yes. Backups are needed not only in case of server problems. They help restore the website after a hack, developer mistake, failed update, accidental file deletion or database corruption.
