- Implement strong authentication- Two-factor authentication (2FA) is probably the most important web security protocol. It is an excellent solution for securing your private information. It is one of the most popular means of authentication. Two-factor authentication generates codes by using a valid user’s cell phone number or a token generated by an application for a smartphone or a mobile device. This means that if a hacker steals your password, they are not able to log in unless you provide your cell phone number or the token generated by the application. Everybody knows that passwords are a vulnerable target to theft. Relatively simple passwords can be quickly hacked.
- Avoid errors that reveal too much- Make sure that your website shows all of its code as clearly as possible. If it’s difficult to decipher a piece of code, the chances of it being exploited are higher. For example, using commas or brackets for error messages and what-ifs. Be aware of too many warnings that show things you do not want to be exposed to, like whitespace, padding, etc. Make sure that your error messages are unreadable by evil code, or coded with images, like the error message from the Google Chrome browser. If you have more than one view for code, you may write a custom error message for every view. As well, the whitespace in them often hides otherwise unwanted code in those cases. The best way to hide un-needed lines of code is by placing them into the Comments, or Comments block.
- Run automatic vulnerability scanning- The first step in defending against security vulnerabilities is to take an automated approach. Various companies perform this type of security scanning of their website. Moreover, when you choose one of these companies to perform your vulnerability scans, make sure that you understand the severity of the issues. There is always the right approach for each situation. Therefore, it is always recommended to assess the security risk you face. Based on this assessment, you can decide which security measures will be enough for the expected level of risk. When a flaw is found in the source code of a plugin or web page, you must check the plugin or web page for the presence of the vulnerability.
