Android READ_LOGS is a permission that allows an app to read system and application logs on the device. Logs can expose debugging details, activity traces, and sometimes sensitive data, so access to them is tightly restricted in modern Android builds.
What this permission means in Android
READ_LOGS is an Android permission that controls access to device logs, which can contain debugging output, activity traces, and incidental secrets. Modern Android versions restrict this permission tightly because logs often reveal more than developers expect, including application behaviour, system state, and user or session details.
The key issue is not just visibility, but data density. Logs are designed for troubleshooting, so they often capture the very information defenders rely on to understand failures, while also creating a high-value target for anyone seeking sensitive operational context.
Why log access is sensitive
Device logs can expose authentication tokens, request parameters, URLs, file paths, stack traces, and other operational details that should not be broadly readable. Even when a log line is not obviously secret on its own, repeated lines can be correlated into a fuller picture of application flow, user behaviour, or security controls.
That makes log access a confidentiality boundary as well as a diagnostics feature. If an application can read logs without a strong business need, it may be able to observe information emitted by other apps or system components and use that visibility for reconnaissance or abuse.
For application hardening, this is part of the broader Kotlin and Android Secure Coding Guide perspective: reduce what is written to logs, and treat log output as potentially sensitive data rather than harmless debug text.
How READ_LOGS is handled in practice
Android has progressively narrowed who can obtain log access, because broad log visibility undermines app isolation and can leak data across process boundaries. In practical terms, this means developers should assume that logs are not a safe place for secrets, and operators should assume that any permissive logging configuration expands the attack surface.
Organisations should also distinguish between developer debugging, production telemetry, and on-device log access. The same message that is useful in a test build may become a security liability if it persists in release builds or if a privileged app can harvest it from the device.
Where logging is unavoidable, minimise sensitive fields at the source, keep retention short, and review whether an app truly needs log-reading capability at all. The permission should be treated as exceptional, not routine.
What to look for during review and incident response
If READ_LOGS is present in a manifest or package review, the question is not only whether the permission is declared, but why the app needs it and what information it could observe. A legitimate support or diagnostics tool may justify some access, but the same permission in an unrelated consumer app is a red flag.
In incident response, logs deserve the same scrutiny as other sensitive artefacts. If an app or device is suspected of compromise, review whether logs may have exposed credentials, tokens, identifiers, API activity, or operational details that could support follow-on abuse.
Where log exposure is part of a wider device or application compromise, the response should include rotating any exposed secrets, invalidating affected sessions where possible, and correcting the logging behaviour that created the exposure in the first place.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP ASVS, NIST SP 800-53 Rev 5 and CIS Controls v8 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP ASVS | V16 — Security Logging and Error Handling | READ_LOGS is directly about log exposure and log handling. |
| Recommendation — Review logging so sensitive data is not written or exposed to unintended readers. | ||
| NIST SP 800-53 Rev 5 | AU-3 — Content of Audit Records | Audit log content must be controlled because logs can reveal sensitive operational data. |
| AU-9 — Protection of Audit Information | READ_LOGS concerns who can read and protect audit and system log information. | |
| Recommendation — Limit audit record content to what is needed and avoid sensitive detail leakage. Restrict access to logs and protect them from unauthorized disclosure. | ||
| CIS Controls v8 | CIS-8 — Audit Log Management | The term centers on managing and protecting log data from misuse or exposure. |
| Recommendation — Centralise, protect, and review logs so access is limited to authorised use. | ||
| ISO/IEC 27001:2022 | A.8.15 — Logging | Android log access is a logging-control issue with confidentiality implications. |
| Recommendation — Define what is logged, who may access it, and how log data is protected. | ||
