In addition to Linux, Jason has experience supporting proprietary Unix operating systems including AIX, HP-UX, and Solaris. Ways to prevent attackers from breaking into your systems, even when they have physical access to your machine. Jason Cannon I help IT professionals level-up their careers by teaching them practical Linux skills.
- By seeing the system from the inside out, it can provide more specific details than the average vulnerability scanner.
- Red Hat does not endorse any of these materials as preparation guides for exams.
- By learning the purpose of each daemon, students will learn how to greatly decrease a hosts’ network presence.
- If this isn’t suitable in a specific situation, remote logins as root should be disabled.
They also act as assignments to help you prepare for the scenarios you will encounter on the Linux Hardening and Security Lessons Server Hardening exam. Get unparalleled visibility into identities, accounts, and privileged access — all in one interface. The course also investigates platform security features such as secure boot and trusted execution environments using a QEMU emulator. This cookie collects personal information such as your name, which pages you visit on our website, your history on our website, your purchases from IAPP, and the like.
The most important part of BIOS security is the easiest and most obvious – a secured BIOS should require password authentication for access. Use a secure password that follows the same policy that the rest of your operating-system-level passwords use. Pick a password that is different than any of the other passwords that you use for your system.

Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding. Use Red Hat Satellite server to implement an OpenSCAP policy. Configure system auditing Write rules to log auditable events.
Nixarmor is a set of shell scripts to harden Linux systems and help with security automation. JShielder is a security tool for Linux systems to make them more secure by adding system hardening measures. A general rule for a strong password would be one that is at least 8 characters long and has at least one letter, one number, and one special character.
The privileged account attack surface is not just humans and employees, but also increasingly involves machines and vendors. In cloud environments, privileged access and accounts may be dynamic and ephemeral, further complicating efforts to gain visibility and control over this massive risk. Learning how to effectively navigate and interact with Linux can be an important part of your learning journey in cybersecurity.
How to do security hardening in Linux?
- Create a new sudo user.
- Set up a Firewall.
- Install and configure Fail2ban firewall.
- Configure SSH.

Thank you for your interest in Linux Foundation training and certification. We think we can better serve you from our China Training site. Stay up to date with the newest courses, certifications, and promotions from the LF training team. The instructor provides thorough details of almost all security essentials for the Linux systems.
Linux is also a rich environment for adversaries who are likely to invest time to compromise an embedded Linux target, in order to establish a versatile and persistent presence. To this end the course will also help teams identify and manage common vulnerabilities and exposures through the use of well-known testing and vulnerability assessment tools. The Yocto build system is used to illustrate how security choices (compiler options, container settings, access control models, etc.) can be implemented at a distribution level.
