Ensure Appropriate Core Dump Limits Are Set

DüşükDüzey 2Manuel incelemetdsql

Açıklama

Core dumps of TDSQL processes may contain sensitive data (encryption keys, passwords, query data). Core dump generation should be restricted in production. Note: TDSQL's start.sh sets ulimit -c unlimited by default.

Nasıl denetlenir

Denetim yöntemi: Manuel inceleme

Bu öneri otomatik olarak denetlenemez. --include-manual parametresini verdiğinizde tarama bunu bu talimatlarla birlikte listeler.

Run ulimit -c for the TDSQL service account, cat /proc/sys/kernel/core_pattern and grep -r 'ulimit.*-c' <tdsql>/bin/start.sh (TDSQL start.sh sets unlimited). Core dumps must either be disabled or written only to a restricted directory (e.g. /var/core/tdsql, mode 700, owned by tdsql) with a size limit set by policy.

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

# Create a restricted core dump directory mkdir -p /var/core/tdsql chmod 700 /var/core/tdsql chown tdsql:tdsql /var/core/tdsql echo 'kernel.core_pattern = /var/core/tdsql/core.%e.%p.%t' >> /etc/sysctl.conf sysctl -p # Modify start.sh for production: # From: ulimit -c unlimited # To: ulimit -c 0 (or a reasonable limit)
