Nowadays, computers which connect to the web are highly vulnerable to attackers. While it's not possible to make your machine immune, you can make it difficult for such intruders to compromise your system. Through there's no golden rule, security is something that needs attention. With open-source based software, it takes just a bit of effort to secure your machine. Here are some tips on how to secure your Linux-based system.
Physical security is the most important prerequisite in keeping your machine safe. Limiting access to your computer is vital to curb the risk of data theft and compromise. If it's not possible to lock your computer in a safe location, protect it using a hard-to-decipher BIOS password. This will help you prevent unauthorized access to your system.
You should also restrict root access in order to ensure that admin's tasks are isolated from ordinary users. When executing a task requiring super user privileges, one should be prompted for a password. The usage of specific commands should also be limited to the system administrators. Though some may find this to be irritating, it goes a long way in averting potentially harmful alterations to the system.
Firewalls are also essential in protecting individual computers within a network. These are configured to filter out unauthorized traffic into and out of a computer. Some knowledge in networking is required for one to work with firewalls. Most Linux distributions ship with an enabled firewall, though some may require one to create manual regulations to allow additional functionality.
Avoid auto-mounting devices onto your machine. You can use the available customization feature to disallow auto-mounting of CDs and USB drives when they're inserted. Here, you can also disable file-sharing across networks and prompt users to enter a password before they can access such devices. This prevents a situation where an unauthorized person accessing and copying data stored within the machine.
As part of system administration, it's good to check the integrity of installed software. The RPM package provides a quick means of assessing the system files in the computer. There are also other open-source file integrity checking tools that you could use.
Linux based systems are largely immune to worms and viruses tailored for other operating systems. However, attackers have developed clever ways of accessing data in such computers. In addition, most users are connected to the internet for long periods. This creates loopholes which hackers can exploit. It's therefore good to have Linux security software installed to reduce such vulnerabilities.
