To enhance Linux security, assess vulnerabilities, secure physical access, configure servers for maximum security, stay up-to-date on security issues, create policies for worst-case scenarios, safeguard root password, use strong passwords, and implement security tools like a firewall and antivirus software. Avoid unnecessary software and services, wireless networks, and reporting helpful information to hackers. Keep the system up-to-date with patches and updates.
You can enhance the security of Linux® by assessing vulnerabilities, securing physical access to machines, configuring servers for maximum security, staying up-to-date on security issues, and creating policies to handle worst-case scenarios. It’s also advisable to safeguard the root password, use strong passwords, and perhaps even use a boot loader password. Some of the protections used to enhance the security of Linux® are the same ones used to enhance the security of any operating system.
When assessing vulnerabilities, consider refraining from installing unnecessary software – software cannot be “attacked” if it is not installed. Enabling unnecessary services should also be avoided. For example, if you don’t allow people to upload files, there’s really no need for services like File Transfer Protocol (FTP). If possible, avoid connecting to a wireless network, especially if you’re using a server. Place the servers in a locked room and don’t allow the machines to report information that could be of help to a hacker, such as software names and versions.
It is extremely important that the root password meets generally accepted standards for creating strong passwords and that it is protected on a network or kept in a safe place in the case of a non-networked personal computer (PC). You can also improve Linux® security by implementing a strong boot loader password and completely removing the accounts of anyone who no longer needs network access. All data associated with the account must be backed up before removal.
Linux® security is also enhanced by using Linux® security tools such as a firewall, antivirus software, or Linux® with Advanced Security. Disabling the local firewall simply because you have a firewall at the perimeter does not comply with the Linux® security enhancement. Having only one layer of protection makes things easier for a hacker. Several layers often make a hacker lose his temper or fear that suspicious activity will be discovered and traced back to its source.
Vulnerabilities in open source software are usually discovered very quickly. They are also almost always fixed just as quickly by patches written by the distribution’s international community of programmers. These patches or updates are then released and made available for free via download. That’s why it’s very important to keep your system up to date, which can be an automated process. Following these basic guidelines for enhancing Linux® security will help you avoid data corruption, data loss, and downtime.
