In this lesson

Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: data at rest with GPG and LUKS2, data in transit with OpenSSL, TLS, and WireGuard, weak algorithms to remove, hashing and HMAC, and certificates, from trusted root stores to ACME, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.

Preview the topics
  • A laptop that holds unreleased films must stay unreadable if it is stolen, whatever the files on it. What fits best?
  • A scan shows that the catalog site still accepts TLS 1.0. What should the admin change?
  • Internal tools at Pinecrest use certificates from the company’s own CA, and every Rocky Linux server must trust them. What should the admin do?
