The first step to securing your server is to understand who has access to it. This includes both authorized users, such as employees or contractors, and unauthorized users, such as hackers.
Authorized Users
Authorized users are those who have been granted permission to access your server. This permission can be granted explicitly, such as by creating a user account for an employee, or implicitly, such as by allowing access to a public website.
Unauthorized Users
Unauthorized users are those who have not been granted permission to access your server. This includes hackers, who may try to gain access to your server through vulnerabilities in your software or network configuration.
How to Protect Yourself from Unauthorized Access
There are several things you can do to protect your server from unauthorized access, including:
- Use strong passwords. Your passwords should be at least 12 characters long and contain a mix of uppercase and lowercase letters, numbers, and symbols.
- Enable two-factor authentication. Two-factor authentication requires users to enter two pieces of information, such as a password and a code sent to their phone, before they can log in.
- Keep your software up to date. Software updates often include security patches that fix vulnerabilities that could be exploited by hackers.
- Use a firewall. A firewall is a network security device that can block unauthorized access to your server.
- Monitor your server activity. Regularly monitor your server logs to look for any suspicious activity, such as failed login attempts or attempts to access sensitive files.
