Join Shawn Powers as he teaches you how to prepare your Linux system with a security-focused mindset.

Gain an understanding of various authentication methods, such as RADIUS, TACACS+, LDAP, and Kerberos; encryption methods, such as using SSL to encrypt web traffic or LUKS to encrypt hard drive data; alternatives to using USB drives; and disk partitioning.

Learn how to secure your Linux system at boot by using the BIOS, UEFI, or boot loader; how to configure multi-factor authentication (MFA), such as 2FA; how to manage users in order to prevent the sharing of IDs and disable root login via SSH; how to disable hosts and unused or unsecure services; how to enable SSL/TLS and auditd; and more.
