Besides increasing the length, the variety of used characters is important. One trick that is simple and powerful is adding a single character many times to your password (e.g. Tips to enhance your password: use longer passwords to make brute force password guessing much harder. So system hardening should also apply to the strength of your passwords. This is a serious risk as automated tools can perform many guesses per second, often discover weak passwords in just a few seconds. Not during development and especially not for production purposes. Why a strong password matters: weak passwords don’t belong on systems. For this reason, the password should be a strong password.Ī bad start of server hardening. This user will be added to the administrative group, allowing him or her to become root. Use strong passwordsĪfter the first installation steps, the creation of a user account is performed. Consider reinstalling the system, or use the hardening measures as part of a future installation. If you already have a system running, the most likely these steps can’t be easily applied after the fact. The first few hardening improvements can be done during the installation. So while the hardening steps are similar, keep always the role of the system in mind. ![]() These activities are less likely on servers, where typically data integrity and availability are more important. Privacy might be an important focus area. Desktop users are most likely using it for browsing the web or reading emails. The only difference is the purpose of the machine. The process of Ubuntu system hardening is very similar for desktops and servers. Although there are some specific Ubuntu security features, most of the hardening tips can be universally applied to other Linux distributions. This can be done by adding, adjusting, or removing certain components of the Linux system.ĭuring this steps in this guide, we will apply a combination of measures to improve the security of your Ubuntu installation and configuration. Those items that pose the most risk to the system are adjusted by taking specific security measures. System hardening is a technical process of increasing the security of a Linux system by reducing its attack surface. If you are new to system hardening, let’s start with a definition: Ubuntu desktops and servers need to be configured to improve the security defenses to an optimal level. While Ubuntu has secure defaults, it still needs tuning to the type of usage. Firewall installation and configurationĮvery Linux distribution needs to make a compromise between functionality, performance, and security.I'm sure it's something pretty simple that I'm doing wrong!Įrr. ![]() To be frank I am still winging it when it comes to installing software on (L)ubuntu. (see at end)įollowing instructions, thinkingrock (nor thinking nor rock) did not show up in Synaptic search. I can add the software sources (though perhaps wrongly) but installing then gives an error after a long list of activity. ![]() I did not have any luck adding either PPA source that I found to my software sources either via GUI or in the command line.
