Ensure Operating System Patches Are Up to Date

HighLevel 1Automatedtdsql

Description

The operating system hosting TDSQL should have the latest security patches installed. Counts pending security updates (dnf/yum updateinfo list security, or apt list --upgradable entries from security pockets). Uses the locally cached repository metadata; refresh it (yum makecache / apt update) before scanning.

How it is checked

Audit method: Shell command

shell

if command -v dnf >/dev/null 2>&1 || command -v yum >/dev/null 2>&1; then pm=$(command -v dnf || command -v yum); out=$($pm -q updateinfo list security 2>/dev/null) || exit 1; printf '%s\n' "$out" | grep -c '[^[:space:]]' || true; elif command -v apt >/dev/null 2>&1; then out=$(apt list --upgradable 2>/dev/null) || exit 1; printf '%s\n' "$out" | grep -ci security || true; else exit 1; fi

Expected output: 0

How it is fixed

Fix method: Guidance or infrastructure patch

Apply security updates during a maintenance window: yum update --security (RHEL/CentOS) or apt update && apt upgrade (Debian/Ubuntu), restarting TDSQL components one node at a time.
