What You Can Read in the Current Catalog
FolioVista Books is a focused catalog for readers who want technical digital books, practical guides, manuals, and free sample chapters without generic filler. The current books page brings together two main reading paths. One path starts with Operational Bug Bounty Fieldwork and introduces the discipline required for authorized testing. The other path starts with Practical Layered Security for Small Platforms and walks through the realities of security ownership, from host hardening through browser and domain trust. Both paths are practical, but they solve different reader needs.
Operational Bug Bounty Fieldwork
Operational Bug Bounty Fieldwork is useful for readers who want a better foundation before they move deeper into reconnaissance or reporting habits. The public sample makes one core point very clear: scope is a contract, not a suggestion. That matters because a target can look public, interesting, or technically exposed and still be out of scope. A bug bounty learner often needs this kind of framing early, because technical curiosity alone is not enough. The sample pushes readers to think about permissions, reportability, and testing boundaries before they treat a finding as valid work.
Practical Layered Security for Small Platforms
Practical Layered Security for Small Platforms covers a different but related problem space. Small platform owners often assume that managed hosting removes most of their security burden. The sample chapters challenge that assumption directly. Faster deployment and easier hosting are helpful, but they do not remove the need for direct security ownership, host review, and recovery planning. The Linux VPS hardening material shows how platform security still depends on operational choices, the SSH timeout recovery chapter shows how troubleshooting should move in a fixed order instead of guessing at one symptom, and the two closing chapters carry that same discipline into the browser and the domain layer -- the hardening headers that control how browsers enforce trust, and the rendering and DNS-level protections that close out the book's public sample.
That fixed order is one of the strongest practical ideas on this page. The SSH timeout recovery sample explains that one visible problem can have several causes, so readers should check interface and IP state first, then the route or gateway, then the SSH service, and only after that verify firewall rules, explicit SSH allowance, and Fail2ban status. This approach reduces confusion because a route issue can look like a firewall issue, a ban can look like a service failure, and a daemon problem can look like total network loss. Readers who prefer calm, structured troubleshooting will see that pattern immediately in the sample chapters.
