One is not to be too careful! As developers, a large part of our job is to ensure that the sites and plug-ins we are building are secure. Enterprises need faster solutions with increasingly complex functions. This is a good development, but building complex projects also requires appropriate security settings. WordPress security is one of the most important aspects of website development. As functional complexity increases, many developers miss the basic web site and web application development security principles. As a result, a flawed website will be created that is exposed to cyber attacks and other risks.
Therefore, when building the project, several basic website and web application development security protocols must be implemented. Here are 16 security tips for web developers to help keep your site safe and healthy. 1. Understand the data that needs to be protected. One of the most important website development security principles is to store only the necessary data. When developing a project, you need to ask three questions: What data should companies store? What sensitive data does the company need to encrypt? If the data is damaged for any reason, how much loss will it bring to the company? Storing more sensitive data increases exposure risk. If sensitive data needs to be stored, it must be encrypted to make it difficult to access.
2. When designing websites, plug-ins or topics that implement role management and access control, it is very important to grant users as low permissions as possible. You must restrict permissions so that users only get the content they need and cannot access other areas. For example, contributors can create new posts and pages, but they must be limited to not publishing. Editors must be able to create and post new posts, but not change the design or plug-in. Similarly, when developing specific features to be restricted in plug-ins or themes, you must create a new word press user role during installation. If you report these conditions to the administrator, each user who uses the plug-in or theme being developed will be assigned the correct role.
The following is a quick illustration of the structure. This method can limit the possible harm caused by intruders, so the problem is minimized. You can also limit the damage caused by errors or errors that disrupt the site area where curious users should not actually exist. In addition, access rights in the development team must be restricted according to different roles. 3. Website authentication of application authentication is a security process. Users can confirm their identity to access the limited area of the website. When developing themes or plug-ins, some data needs to be limited when users see it. Therefore, it is important to add checks to the code to ensure that users accessing restricted data are authenticated and have the correct user roles.
Similarly, when building a website, you can protect user data by implementing effective account management methods, such as mandatory passwords and multi-level authentication. Dual authentication is one of the most commonly used methods to implement authentication. 2fa (secondary authentication) is a secondary process. In addition to the website password, additional code or OTP (one-time password) is required to log in to the website. The OTP is usually sent to other devices through identified 2fa applications (such as SMS, phone or Google authenticator, authy, duo security, etc.). By implementing 2fa, you can safely protect yourself from indiscriminate intrusion attacks.
If you build a website on WordPress, check out the amazing tools to protect your website. Login attempt limit: This tool protects users from malicious intrusion by limiting the number of login attempts. Anti spam and automatic
It also includes logging off disabled users. Wp2fa: using the wp2fa plug-in, you can immediately add two levels of authentication to the website. It also supports multiple 2fa applications, such as Google authenticator, authy, freeotp, duo security, etc. Shield Security: the plug-in does not support 2fa applications, such as Google authenticator and SMS 2fa, but it is very useful for people using yubikey. Wpassword: use this plug-in to apply strong password to WordPress website, prevent too many users who fail to log in, etc. Seamless integration with woocommerce and other third-party plug-ins. 4. Verify before publishing the theme or plug-in. Before the theme or plug-in is released, make sure that the code is as error free as possible. Specific compositor dependencies can be used to detect code vulnerabilities.
Some of the dependencies recommended by WordPress include: Wpthemereview WP coding standards these coding standards have strict coding rules that help protect code, including always escaping data before printing data, using nonce for all requests, deleting data before using requested data, providing appropriate user permissions, etc. These tools are useful when developing your own themes or plug-ins. You also need to check the wpscan security scanner. This is an excellent online website security scanner, which can check whether there are loopholes in the website.
5. Avoid specific PHP functions such as eval() and uninstall(), which can expose system data, expose server data, shut down the server or access all server information of hackers. Here are some PHP functions to avoid as much as possible: Eval (): Eval can execute arbitrary PHP code. If used improperly, the code may be exposed to injection attacks. Serialize() or unserialize(): do not use serialize() or unserialize() while the user provides input. Attackers may exploit these functions maliciously. Arbitrary code can be executed by passing a string with a serialized arbitrary object.
MD5 (): the Internet is full of comments on MD5 () encryption vulnerabilities. Male 1 is considered unsafe. Use better hashing functions such as SHA-2. Sha1(): sha1() is another hash function that cannot be used because of the fast nature of the hash algorithm. It is recommended to use SHA-2 hash algorithm instead of MD5 () in all the latest frameworks. 6. Use the printer to find problems in the code. The printing tool is the default static code analyzer to check the programming and stylistic errors in the source code. Linter’s voice output tone must be friendly in order to continue the project.
Lint code is a good way to find potential vulnerabilities and reduce errors when developing websites or applications. PHP, JS, and HTML development can use specific secure printing. Here are some noteworthy tools for PHP code static analysis: PHP parallel printing Sona lint hymn PHP printing HTML and JavaScript printing can also use sonarlent. Other noteworthy JS printers include: JS lint 7. As unused code and plug-in removal software become more and more complex, the possibility of code vulnerabilities increases. WordPress Themes and plug-ins are no different. Through the increasing functions of HTML 5, CSS and JavaScript, developers can build rich web applications.
But application complexity increases
Blade sword. While helping users provide the expected functions, expand the attack surface of the application. One way to address these vulnerabilities is to remove unused code. Other users may not need all the functions of the website or web application. In each deployment, unnecessary functions are deleted according to user needs, so as to reduce the attack surface and related risks. If you like developing websites in WordPress, it is recommended to use lightweight themes and plug-ins in code. It can not only protect the website security, but also optimize the search engine. The following are the lightest and fastest word press themes available: 8. Use server-side and client-side authentication. If you prefer to write custom code, you must use both client-side and server-side authentication. Client side validation checks help prevent common errors, such as users entering data incorrectly or forgetting fields. These validations can be captured before invalid data reaches the server, saving time and cost. If client-side authentication occurs only after a round-trip server failure, you may face a delay because the user is not allowed to modify the error immediately, but to tell the user what was wrong. However, client-side authentication alone is not safe enough. You must also use server-side authentication checks. Server side authentication checks protect users from malicious input and other attack vectors. 9. Delete all user input and request data delete user input sanitization is a network security measure used to audit, clean and filter user and API data to prevent harmful code from being inserted into the system. Hackers can insert specific commands and perform operations that may compromise the security of the website. Deleting input helps maintain data integrity and improve system security. 10. When performing security checks for permanently modified applications, you may find some vulnerabilities that sometimes persist. You should understand the root cause of the new vulnerability in order to permanently eradicate the vulnerability, rather than adding some patches. For example, SQL \/ XSS problems are often encountered in the development of topics or plug-ins. In this case, instead of building a hygiene check for each input, you can build a function \/ class and create a policy through which all data must be passed every time there is user input. 11. Wrong security configuration and anti default security settings occur when the security settings are not defined and implemented and the default values are retained. If security controls are not implemented or errors are implemented at the same time, the built theme, plug-in or website is likely to have vulnerabilities. Incorrect configuration often leads to the failure of system, database administrator or developer to correctly configure the application framework, resulting in hackers entering the dangerous open path. Make sure your preferences are secure and do not automatically set your password if necessary. For example, if the plug-in uses a directory where users can upload files, always ask the user to set a password and directory path. 12. Maintaining network security with the latest information and the latest information is an evolving field. Only by understanding the latest security updates and new risks can we understand the development situation and mitigate new code threats. As a developer, what are the best practices to help you understand news information, write safer code, protect code, better organize code, and better handle user input.
