Oracle Security & Operations
Hardening, patching, auditing, automation
Security and operations is where Oracle databases quietly accumulate risk: patches deferred because they're scary, audit settings nobody owns, hardening checklists with 200 items and no priority. These guides cut that down to what actually matters — quarterly patching demystified (CPU vs RU vs RUR), a hardening checklist that isn't busywork, auditing that answers real questions, and the automation that makes all of it repeatable instead of heroic.

- The Oracle Hardening Checklist That Actually Matters
Oracle hardening without the busywork: close default-password accounts, tame PUBLIC and ANY grants, lock the listener, encrypt at rest, and audit what matters. - Oracle Patching, Demystified: CPU, RU, RUR — and What Changed in 2026
Oracle patching in 2026: what a Release Update is, why RUR is dead, the new monthly CSPU and MRP, and how to apply it with OPatch and datapatch — no outage.
