Logs may contain personal and other sensitive information, or the data may contain information regarding the application's code and logic.\n\nIn addition, the collected information in the logs may itself have business value (to competitors, gossip-mongers, journalists and activists) such as allowing the estimate of revenues, or providing performance information about employees.\n\nThis data may be held on end devices, at intermediate points, in centralized repositories and in archives and backups.\n\nConsider whether parts of the data may need to be excluded, masked, sanitized, hashed, or encrypted during examination or extraction.\n\nBuild in tamper detection so you know if a record has been modified or deleted Store or copy log data to read-only media as soon as possible All access to the logs must be recorded and monitored (and may need prior approval) The privileges to read log data should be restricted and reviewed periodically\n\nIf log data is sent over untrusted networks (e.g. for collection, for dispatch elsewhere, for analysis, for reporting), use a secure transmission protocol Consider whether the origin of the event data needs to be verified Perform due diligence checks (regulatory and security) before sending event data to third parties\n\nSee NIST SP 800-92 Guide to Computer Security Log Management for more guidance.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
