Hands-on Linux Host Security for SysAdmins [Video]: Gain critical familiarity with the best security tools (AIDE, Rootkit Hunter (rkhunter), and chroot) and access-limiting, auditing tools on host Linux systems

Gaining access to a local user is the first thing a system intruder attempts. Indeed, local users themselves can also cause havoc with your system, especially because they are real people who can exploit your personal data with minimal human engineering. This course will take you through how to lock up your host more securely.

In this course, you will learn the skills you need to lock your Linux server down and protect your data and other resources by tuning the Linux kernel using various commands, practical ports, and service monitoring. You will learn how to perform operations that change the apparent root directory to jail (mis)users. You will learn about Linux Auditing System tools and associated traceability issues, and then work hands-on with malware detection tools, rootkits, and more. You will also learn to limit user access to resources and how to deal with processing and statistics.

  • Examine the Linux procfs filesystem, use systcl to read and write to procfs files, and work hands-on with ASLR
  • Perform port scanning and network service detection to reduce exposure to the outside world
  • Make use of chroot to lock users into jails to restrict their access and secure environments
  • Perform security practicals without the Linux auditing system installed
  • Monitor system changes with AIDE (Advanced Intrusion Detection Environment)
  • Use rootkit hunter to find changes in binaries or additional files monitoring the Linux Server
  • Implement limits and display enforced limits using the command shell built limit, adjust limits, then persist them via the limits.conf file

By the end of this course, you will have gained the skills and knowledge you need to make sure that your local security is tight and secure. You’ll be confident about hardening your Linux servers so intruders have more hurdles to cross.
