About Lesson
When installing a new WordPress system, it is important to perform a number of security actions to protect the site from the start.
 
  1. Choose a Complex Password: Use a non-trivial username and a password that includes uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable personal information.
  2. Change the Default Username: It is highly recommended to change the default username from “admin” to a custom username, as mentioned. Using the default username is a common target where attackers may attempt to break in to determine your username.

    When users manually set their username, especially as “admin,” it can create a security vulnerability. This is a known security gap, so it’s important to ensure that all users on the site use usernames other than the risky default.

  3. Emphasize Changing the Default Prefix of Database Tables (wp_): The recommendation to set unique prefixes for tables in the database is definitely an important step to enhance your system’s security. Instead of using a prefix like “wp_” that serves as a maintenance background and is known to potential attackers, you can choose a unique prefix to protect your database.

    For example, you can choose a prefix based on the site’s name or an identifier unrelated to WordPress directly. The prefix should be something you have the right to use and not easily guessable, making it difficult for an attacker to guess the internal structure of the database and approach it.

    For instance, if you install a system named “MyAwesomeSite,” you can choose a prefix like “mas_” instead of “wp_”. This will make it harder for an attacker to guess the database structure and get closer to it.

  4. Set a Complex Password for the Database: During installation, the system will provide you with the option to set a password. You are responsible for ensuring that the password you use meets high criteria such as including uppercase and lowercase letters, numbers, special characters, and is over 8 characters long. Generally, you will receive instructions in the installation guide or the system’s user interface that you are installing.
