Which practices constitute common logging best practice?

Explanation:
The main idea is that solid logging practices create visibility, integrity, and accountability across the environment, which is essential for monitoring, incident response, and forensics. Centralized logging brings logs from many systems into one place, making it possible to search efficiently, correlate events, and retain data long enough to investigate incidents or meet compliance. Time-synchronization with a reliable NTP service ensures all devices stamp events with a consistent clock, so the order of actions across many hosts can be accurately reconstructed during investigations. Integrity protection, such as signing, tamper-evident or append-only storage, and protected transmission channels, helps ensure logs remain authentic and inviolate, which is crucial for reliable evidence. Secure storage adds access controls and encryption at rest to prevent unauthorized access or modification, safeguarding the logs from insider or external threats. Regular review means logs aren’t collected and forgotten; they are actively analyzed, with alerts tuned and investigations initiated when anomalies appear, supporting proactive defense and compliance oversight. Log practices that decentralize logs, skip integrity checks, or rely on local retention only undermine visibility and trust. Without centralization, correlating events across systems becomes nearly impossible, and tampering can go undetected. Relying on local retention increases the risk of data loss if a host is compromised. Focusing only on failed logins or avoiding reviews leaves many relevant events unseen, and storing logs on user desktops removes central control and makes protection and collection difficult.
