What it does

Elasticsearch Audit is an agent skill from aspectrr/deer. Enable, configure, and query Elasticsearch security audit logs. Use when the task involves audit logging setup, event filtering, or investigating security incidents like failed logins.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Search implementation, Security review and Security operations. It works with Elasticsearch. The repository describes itself as: 🦌 The AI Elasticsearch Engineer. The licence is MIT.

When your agent uses it

The task involves audit logging setup
Event filtering

Example prompts

“/elasticsearch-audit”

What it can do on your machine

Read from SKILL.md and the folder at commit e4f9845. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Elasticsearch Audit loads about 1.7k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 401 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~51
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Elasticsearch Audit Logging

Enable and configure security audit logging for Elasticsearch via the cluster settings API. Audit logs record security events such as authentication attempts, access grants and denials, role changes, and API key operations.

For detailed API endpoints and event types, see references/api-reference.md.

Jobs to Be Done

Enable or disable security audit logging on a cluster
Select which security events to record (authentication, access, config changes)
Create filter policies to reduce audit log noise
Query audit logs for failed authentication attempts
Investigate unauthorized access or privilege escalation incidents
Set up compliance-focused audit configuration
Detect brute-force login patterns from audit data
Configure audit output to an index for programmatic querying

Prerequisites

Item	Description
Elasticsearch URL	Cluster endpoint (e.g. `https://localhost:9200` or a Cloud deployment URL)
Authentication	Valid credentials (see the elasticsearch-authn skill)
Cluster privileges	`manage` cluster privilege to update cluster settings
License	Audit logging requires a gold, platinum, enterprise, or trial license

Enable Audit Logging

bash

curl -X PUT "${ELASTICSEARCH_URL}/_cluster/settings" \
  <auth_flags> \
  -H "Content-Type: application/json" \
  -d '{
    "persistent": {
      "xpack.security.audit.enabled": true
    }
  }'

Audit Output

Output	Setting value	Description
logfile	`logfile`	Written to `<ES_HOME>/logs/<cluster>_audit.json`. Default.
index	`index`	Written to `.security-audit-*` indices. Queryable via the API.

bash

curl -X PUT "${ELASTICSEARCH_URL}/_cluster/settings" \
  <auth_flags> \
  -H "Content-Type: application/json" \
  -d '{
    "persistent": {
      "xpack.security.audit.enabled": true,
      "xpack.security.audit.outputs": ["index", "logfile"]
    }
  }'

Select Events to Record

Include specific events only

bash

curl -X PUT "${ELASTICSEARCH_URL}/_cluster/settings" \
  <auth_flags> \
  -H "Content-Type: application/json" \
  -d '{
    "persistent": {
      "xpack.security.audit.logfile.events.include": [
        "authentication_failed",
        "access_denied",
        "access_granted",
        "anonymous_access_denied",
        "tampered_request",
        "run_as_denied",
        "connection_denied"
      ]
    }
  }'

Event types reference

Event	Fires when
`authentication_failed`	Credentials were rejected
`authentication_success`	User authenticated successfully
`access_granted`	An authorized action was performed
`access_denied`	An action was denied due to insufficient privileges
`anonymous_access_denied`	An unauthenticated request was rejected
`tampered_request`	A request was detected as tampered with
`connection_granted`	A node joined the cluster (transport layer)
`connection_denied`	A node connection was rejected
`security_config_change`	A security setting was changed (role, user, API key, etc.)

Filter Policies

Filter policies suppress specific audit events by user, realm, role, or index.

bash

curl -X PUT "${ELASTICSEARCH_URL}/_cluster/settings" \
  <auth_flags> \
  -H "Content-Type: application/json" \
  -d '{
    "persistent": {
      "xpack.security.audit.logfile.events.ignore_filters": {
        "system_users": {
          "users": ["_xpack_security", "_xpack", "elastic/fleet-server"],
          "realms": ["_service_account"]
        }
      }
    }
  }'

Query Audit Events

Search for failed authentication attempts

bash

curl -X POST "${ELASTICSEARCH_URL}/.security-audit-*/_search" \
  <auth_flags> \
  -H "Content-Type: application/json" \
  -d '{
    "query": {
      "bool": {
        "filter": [
          { "term": { "event.action": "authentication_failed" } },
          { "range": { "@timestamp": { "gte": "now-24h" } } }
        ]
      }
    },
    "sort": [{ "@timestamp": { "order": "desc" } }],
    "size": 50
  }'

Search for access denied events

bash

curl -X POST "${ELASTICSEARCH_URL}/.security-audit-*/_search" \
  <auth_flags> \
  -H "Content-Type: application/json" \
  -d '{
    "query": {
      "bool": {
        "filter": [
          { "term": { "event.action": "access_denied" } },
          { "range": { "@timestamp": { "gte": "now-7d" } } }
        ]
      }
    },
    "sort": [{ "@timestamp": { "order": "desc" } }],
    "size": 20
  }'

Deployment Compatibility

Capability	Self-managed	ECH	Serverless
ES audit via cluster settings	Yes	Yes	Not available
ES logfile output	Yes	Via Cloud UI	Not available
ES index output	Yes	Yes	Not available
Filter policies via cluster settings	Yes	Yes	Not available

Guidelines

Prefer index output for programmatic access

Enable the index output to make audit events queryable. The logfile output is better for shipping to external SIEM tools via Filebeat but cannot be queried through the Elasticsearch API.

Start restrictive, then widen

Begin with failure events only (authentication_failed, access_denied, security_config_change). Add success events only when needed — they generate high volume.

Monitor audit index size

Set up an ILM policy to roll over and delete old .security-audit-* indices. A 30-90 day retention is typical.
