Incident Response and Computer Forensics

Jason T. Luttgens, Matthew Pepe, Kevin Mandia

Luttgens, Pepe, and Mandia's working playbook for running an enterprise IR engagement: pre-engagement readiness, evidence acquisition, network and host forensics, and the project-management discipline that separates a controlled response from a panic.

Practical Linux Forensics

A Guide for Digital Investigators

Bruce Nikkel

Bruce Nikkel's reference for forensic analysts working post-mortem on Linux images: filesystems, journaling, logs, persistence locations, and the chain of custody discipline around them.

Read this if

Junior-to-senior incident responders, SOC leads, and CISOs who need the canonical cross-discipline reference for what a real IR program looks like end to end. Strongest as a structural primer — the maturity model implicit in the book is still the field's de facto baseline.

Incident responders and forensic analysts working modern Linux systems. Nikkel covers ext4 / XFS / Btrfs internals, systemd journaling, persistence locations, and the chain-of-custody discipline that distinguishes evidence from notes. The post-systemd reference the field needed.

Skip this if

Readers wanting current tradecraft on identity-attack response (AAD, OAuth abuse, golden SAML), cloud-IR specifically, or modern EDR-driven hunting; the book is largely on-prem 2014. Pair with cloud-IR-specific resources (Mandiant blog, AWS / Azure incident-response runbooks) for the missing layer.

Windows-only forensic analysts, or beginners without IR experience. The book assumes filesystem fluency and command-line forensics comfort.

Key takeaways

Readiness is the engagement: most of what determines the outcome of an IR is decided before the call comes in.
The acquire-then-analyze discipline still holds; cutting that corner is what produces the bad-headline retrospectives.
The book's project-management chapters are the underrated half — most failed responses are management failures, not technical ones.

Modern Linux forensics is not just "parse syslog"; systemd, journald, and the move to overlay-based containers each created new artifact classes.
The book's chapter on persistence enumeration is the cleanest in print; cron, systemd timers, init.d, profile files, all named.
Most cloud workloads are Linux, which means most cloud-incident forensics is Linux forensics; the book is the right starting reference.

How they compare

Incident Response and Computer Forensics and Practical Linux Forensics are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Both books target intermediate-level readers, so the choice is about topic, not difficulty.

Incident Response and Computer Forensics and Practical Linux Forensics both cover Forensics, Defensive, so reading them in sequence reinforces the same material from different angles.
