Security architecture: principles and controls

The 4 pillars of operable security

Useful security covers: prevention (reduce risk), detection (see early), recovery (restore fast), and auditability (prove and understand). Without tested recovery and usable logs, security stays theoretical.

Design principles

Least privilege, segmentation, defense in depth, encryption by default, monitoring, traceable change management, and careful automation. The goal is to limit blast radius and shorten time-to-recovery.

Practical controls we deploy

MFA where possible, password manager, system hardening, managed patching, EDR/antivirus when relevant, firewalling and filtering, separated networks, encrypted offline or immutable backups, restore testing, centralized logging, alerting, access reviews.

Ransomware: what actually makes the difference

You cannot always block ransomware in time. What matters is restoring cleanly, fast, without paying. That requires encrypted backups, privilege separation, backup storage that is not reachable like a simple network drive, and regular restore tests.

Law-firm case: common requirements

Access traceability, case-based sharing, retention and archiving, role separation, contractual confidentiality, and emergency procedures. Security architecture must support the work, not slow it down.
