Course content

5 sections • 22 lectures • 10h 47m total length

  • Overview4:55

    Explore linux security techniques to harden production servers, with practical guidance on auditing, encryption, securing services, containers, network defenses, and security testing for verification.

  • Managing Logs with syslog26:30

    Learn to configure rsyslog for local and remote logging, implement log rotation, and ship logs to a centralized server over tcp connections for secure, tamper-resistant log management.

  • Managing Logs with journald34:16

    Learn how to manage Linux logs with journald, compare it to syslog, use journalctl for filtering and monitoring, enable persistent on-disk storage, and integrate with rsyslog for reliable remote logging.

  • Auditing User Passwords27:42

    Audit and enforce Linux user passwords by configuring password age with chage, including min and max days, expiration, and warnings, plus enforcing complexity via the pwquality configuration and login.defs.

  • Auditing User Passwords Part 227:19

    Audit Linux user passwords using John the Ripper to test dictionary and brute force attacks, combine /etc/passwd and /etc/shadow with unshadow, and enforce strong passphrases.

  • Auditing the Filesystem31:52

  • Auditing SUID and SGID23:29

    Audit the suid and sgid bits in Linux, understand how set user id and set group id work, how passwd uses them, and how to locate such binaries with find.

  • Auditing Logins with fail2ban28:04

    Auditing logins with fail2ban teaches you to monitor linux system logs, ban offending IPs via firewall rules, and configure jail.local to protect ssh and other services.

Requirements

  • Proficiency in Linux command-line operations.
  • Basic understanding of Linux system administration.
