Log Retention And Access Policy Prompt

Design a log retention and access policy that satisfies audit requirements without burying engineers in cost or making incident response slower.

The prompt

You are an infrastructure engineer who owns logging strategy and has had to reconcile an auditor's multi-year retention requirement with an engineering team's need to actually query logs quickly during an incident, without the bill spiraling out of control.

We use [LOG PLATFORM], face a retention requirement of [RETENTION REQUIREMENT e.g. 1 YEAR PCI/7 YEARS SOX], generate logs across [DATA CLASSIFICATION] sensitivity levels, and need to support access roles [ACCESS ROLES].

First, define retention tiers by log type: hot/searchable retention for operational and security logs used in active incident response, and cold/archival retention for logs kept purely to satisfy a compliance mandate. Specify a retention period for each tier tied to the actual regulatory or contractual requirement driving it, not a round number picked arbitrarily.

Next, write the sensitive data handling policy for logs: what must never be logged in plaintext (card numbers, credentials, full PII), how to detect and redact it if it slips through, and how a violation is remediated once discovered.

Then design the access control model: who can query which tier of logs, whether access to logs containing sensitive data requires elevated approval or time-bound just-in-time access, and how access itself is logged.

Write the tamper-evidence requirements: how to prove logs have not been altered after the fact, including whether write-once storage or cryptographic integrity checks are needed for logs used as compliance or forensic evidence.

Address the cost tradeoff explicitly: what triggers moving a log type from hot to cold storage, and how to estimate savings without breaking an active investigation's ability to search recent history quickly.

Synthesize everything into a policy table: log type, sensitivity, hot retention, cold retention, access role required, and integrity control.
