Companion learning set

Use the resources together.

Move between the free audio course, structured reading, and active recall instead of treating each resource as a separate product.

Certification study plan

Use the audio course and companion books as one learning system.

Use the flashcards after each listening and reading block so recall—not recognition—drives the review.

Five-step cycle

  1. Plan the week

    Choose the lessons for the week, scan the matching book headings, and identify the concepts you expect to learn.

  2. Listen for structure

    Complete the assigned audio lessons and mark terms, examples, or decisions that need a second pass.

  3. Read for depth

    Use the study guide to clarify the lesson, annotate key ideas, and connect related objectives.

  4. Recall without prompts

    Use the flashcards or your own questions before looking at the answer. Separate strong topics from weak ones.

  5. Close the loop

    Open the linked Cyber Wiki articles, revisit missed lessons, and repeat difficult cards until you can explain the concept clearly.

The schedule is Bare Metal Cyber editorial guidance. Adjust the pace for your exam date, prior experience, and practice-test results.

Kernel Module Security

Kernel module security governs which code may extend the operating-system kernel, when modules may load, and how unsupported or unnecessary drivers are prevented from expanding privilege.

Linux Capabilities and Privilege Delegation

Linux capabilities and controlled privilege delegation split broad superuser power into narrower rights so services and administrators receive only the authority required for a task.

systemd Service Hardening

systemd service hardening uses unit-level sandboxing, identity, filesystem, capability, namespace, and resource controls to reduce what a Linux service can do if it fails or is compromised.

Filesystem Mount Hardening

Filesystem mount hardening uses mount boundaries and options to reduce executable content, device access, privilege transitions, and unsafe write behavior on selected filesystems.

Linux Account Lifecycle

Linux account lifecycle management governs creation, modification, suspension, deletion, home directories, shells, group membership, service identities, and residual access from onboarding through deprovisioning.

PAM Authentication Policy

Pluggable Authentication Modules centralize Linux authentication decisions through ordered policy stacks that can combine passwords, lockouts, multifactor methods, directories, and session controls.

Python Dependency Isolation

Python dependency isolation separates project packages and interpreters from system components so version conflicts, unreviewed libraries, and installation side effects do not spread across workloads.

SELinux Policy Enforcement

SELinux policy enforcement uses labels, types, roles, and policy rules to confine processes and data even when conventional ownership and mode bits would permit access.

Shell Script Security

Shell script security reduces command injection, unsafe expansion, silent failure, secret exposure, and destructive mistakes through disciplined quoting, input handling, error checks, permissions, and review.

Access Control Lists on Hosts

Host access control lists extend basic owner-group-other permissions with named user and group entries, default inheritance, and more precise authorization for shared files and directories.

Cloud Configuration Drift

Cloud configuration drift occurs when deployed resources no longer match approved definitions, baselines, or intended architecture.

Cloud Container Security

Cloud container security protects images, registries, orchestrators, nodes, runtime configuration, network policy, secrets, identities, and workloads throughout the container lifecycle.
