Security is a primary surface in Sencho. The **Security** page in the top navigation brings the
capabilities that power [vulnerability scanning](/features/vulnerability-scanning) into one command
center, so you can answer "what should I look at first?" without hunting through other pages. It is
scoped to the active node: the findings and scanner status you see reflect whichever node is selected.

The page is organized into tabs.

## Overview

The overview opens with a status masthead that reads your worst active severity at a glance,
**Secure**, **At risk**, or **Critical**, alongside the critical and high counts and the time of the
last successful scan. Below it, a signal rail summarizes the supporting numbers: scanned images,
fixable findings, secrets, Compose misconfigurations, stale scans, and failed scans. A status strip
shows scanner health (installed source and version, auto-update) and the active node's deploy
enforcement posture.

If a node does not report an overview (for example an older remote node), the page falls back to a
clear "overview unavailable" state and the other tabs keep working.

## Images

Image findings list every scanned image on the active node with its highest severity. Selecting an
image opens the full scan report, where you can review vulnerabilities, suppress a CVE, and export an
SBOM.

## Compose risks

Compose risks surface misconfigurations in your stack definitions rather than image CVEs: privileged
containers, Docker socket mounts, host networking, broad host bind mounts, missing healthchecks, public
database ports, containers running as root, unpinned image tags, and missing restart policies. Each
entry opens its scan report with the specific findings and how to fix them. The [Policy packs](#policy-packs)
tab explains each category in depth.

## Secrets

The secrets tab lists images where Trivy detected exposed credentials or keys, and opens straight to
the secret findings for a scan.

## Policy packs

Policy packs are curated bundles of security expectations for a deployment posture. Sencho ships five
defaults:

- **Homelab baseline**: gentle defaults for a single-operator homelab.
- **Production hardening**: sensible hardening for services that face real traffic.
- **Strict production**: a zero-tolerance posture for critical workloads.
- **Public edge service**: focused on services exposed to the public internet.
- **Internal service**: least-privilege defaults for east-west internal services.

Each pack lists its rules with the severity, what the rule checks, why it matters, and how to fix it.
Every rule is marked **warning** or **enforceable**. In Community, packs are advisory: they explain
what good looks like. Block-on-deploy enforcement is an Admiral capability, configured under
[scan policies](/features/vulnerability-scanning#scan-policies).

## Suppressions

CVE suppressions and misconfiguration acknowledgements are managed here, the same controls available
in Settings. These are governed by the local instance, so this tab is shown when you are on the local
node; switch to the local node to manage them.

## History

The History tab opens the scan history sheet, listing completed scans grouped by image with search and
two-scan comparison. Closing the sheet leaves the tab in place so you can reopen it. The **Scan
history** button in the [Resources Hub](/features/resources) is a shortcut to the same place.

## Scanner setup

Scanner setup manages the Trivy binary for the active node: install the managed binary, update it when
a new release is available, and toggle automatic updates. Trivy is installed independently on each
node. See [Installing Trivy](/operations/trivy-setup) for the full setup options.

## What stays where

Resources keeps its per-image severity badges and scan actions, so you can still scan and inspect an
image from your inventory. Security is the place to review the whole picture; the deeper scanning
workflow (on-demand scans, scheduled fleet scans, scan policies, SBOM and SARIF export) is documented
under [Vulnerability scanning](/features/vulnerability-scanning).
