It enables threat detection, hunting, monitoring, and incident response.<\/p>\n<pre><code class=\"mono\"># Elastic Security runs inside Kibana\r\n# Requires Elasticsearch backend<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-green\">\n<h3>2) Why Elastic Security?<\/h3>\n<p>Strengths: scalable search, flexible ingestion, powerful detection engine, free &#038; open tier. Tradeoffs: operational overhead, tuning required for detection rules, scaling Elasticsearch clusters is non-trivial.<\/p>\n<pre><code class=\"mono\"># Enable Elastic Security app from Kibana\r\nstack_features:\r\n  security_solution: true<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-amber\">\n<h3>3) Elastic Security Architecture<\/h3>\n<p>Data Sources \u2192 Ingestion (Beats, Logstash) \u2192 Elasticsearch \u2192 Detection Engine &#038; Machine Learning \u2192 Kibana Security App (Dashboards, Alerts, Cases).<\/p>\n<pre><code class=\"mono\"># Filebeat ships logs\r\nfilebeat modules enable system\r\nfilebeat -e<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-violet\">\n<h3>4) Core Components<\/h3>\n<p>1) Data Ingestion (Beats, Logstash, Elastic Agent). 2) Data Store (Elasticsearch). 3) Analytics &#038; Detection (rules, ML jobs). 4) Visualisation (Kibana). 5) Response (cases, connectors).<\/p>\n<pre><code class=\"mono\"># Example rule (KQL)\r\nevent.category: process and event.type: start<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-rose\">\n<h3>5) Elastic vs Traditional SIEM<\/h3>\n<p>Elastic: built on Elasticsearch, near real-time search, open APIs, integrated ML. Traditional SIEM: vendor-locked, slower ingestion, costly licenses. Elastic suits cloud-native and hybrid workloads.<\/p>\n<pre><code class=\"mono\"># SIEM Query (KQL)\r\nsource.ip: \"10.0.0.1\"<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-cyan\">\n<h3>6) Elastic Common Schema (ECS)<\/h3>\n<p>Defines a unified schema for log fields (e.g., <code>event.category<\/code>, <code>host.ip<\/code>). ECS standardises data to enable correlation across sources.<\/p>\n<pre><code class=\"mono\">event.action: \"login\"\r\nuser.name: \"alice\"<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-lime\">\n<h3>7) Detection Engine<\/h3>\n<p>Runs rules continuously to detect suspicious behaviour. Rule types: KQL, EQL (event correlation), ML jobs, custom scripts. Alerts can trigger cases, webhooks, or SOAR workflows.<\/p>\n<pre><code class=\"mono\"># Example EQL\r\nprocess where process.name == \"mimikatz.exe\"<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-orange\">\n<h3>8) Timeline &#038; Investigations<\/h3>\n<p>Timeline is the interactive investigation UI: query events, drag &#038; drop observables, visualise sequences, and attach findings to cases.<\/p>\n<pre><code class=\"mono\"># Timeline queries use KQL\/EQL\r\nevent.category: network and destination.port: 443<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-indigo\">\n<h3>9) Case Management<\/h3>\n<p>Analysts can open cases directly from alerts or investigations, assign them to teams, and push to external systems (Jira, ServiceNow, Slack).<\/p>\n<pre><code class=\"mono\"># Create case in Kibana UI \u2192 Security \u2192 Cases<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-emerald\">\n<h3>10) Q&amp;A \u2014 \u201cElastic vs Splunk for Security?\u201d<\/h3>\n<p><span class=\"q\">Answer:<\/span> Elastic offers free\/open, schema flexibility, and integrated ML. Splunk provides mature ecosystem and support but is costlier. Elastic is ideal for cloud-native, Splunk for enterprises with budget and legacy integration needs.<\/p>\n<\/p><\/div>\n<p>      <!-- ===================== SECTION 2 ===================== --><\/p>\n<div class=\"section-title\">Section 2 \u2014 Data Ingestion &#038; Normalisation<\/div>\n<div class=\"card bg-blue\">\n<h3>11) Beats<\/h3>\n<p>Lightweight shippers: Filebeat (logs), Winlogbeat (Windows events), Packetbeat (network), Auditbeat (audit logs), Metricbeat (metrics). Send directly to Elasticsearch or Logstash.<\/p>\n<pre><code class=\"mono\">filebeat modules enable auditd\r\nfilebeat setup<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-green\">\n<h3>12) Logstash<\/h3>\n<p>Pipeline for ingest \u2192 transform \u2192 ship. Parse, enrich, normalise logs to ECS before indexing. Use Grok filters, dissect, or JSON codec.<\/p>\n<pre><code class=\"mono\">filter {\r\n  grok { match =&gt; { \"message\" =&gt; \"%{COMBINEDAPACHELOG}\" } }\r\n}<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-amber\">\n<h3>13) Elastic Agent &#038; Fleet<\/h3>\n<p>Unified agent to collect logs, metrics, and endpoint security data. Managed via Fleet in Kibana. Simplifies deployment compared to multiple Beats.<\/p>\n<pre><code class=\"mono\">sudo elastic-agent install --url=https:\/\/fleet-server:8220 --enrollment-token &lt;token&gt;<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-violet\">\n<h3>14) Integrations<\/h3>\n<p>Elastic has 100+ prebuilt integrations (AWS, Azure, GCP, Okta, Cisco, CrowdStrike). Normalise incoming logs into ECS automatically.<\/p>\n<pre><code class=\"mono\"># Enable AWS CloudTrail integration from Kibana Integrations<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-rose\">\n<h3>15) Threat Intelligence Feeds<\/h3>\n<p>Ingest TI feeds (MISP, OpenCTI, AlienVault OTX) into Elasticsearch. Correlate indicators (IP, domain, hash) with logs to enrich detections.<\/p>\n<pre><code class=\"mono\">indicator.type: \"ip\" and source.ip: 185.*<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-cyan\">\n<h3>16) ECS Normalisation<\/h3>\n<p>Always map fields to ECS before detection. This ensures correlation across sources. Example: map <code>src_ip<\/code> to <code>source.ip<\/code>.<\/p>\n<pre><code class=\"mono\">mutate { rename =&gt; { \"src_ip\" =&gt; \"[source][ip]\" } }<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-lime\">\n<h3>17) Parsing Unstructured Logs<\/h3>\n<p>Use Grok or regex patterns to extract fields. Map to ECS. Avoid leaving logs as raw strings.<\/p>\n<pre><code class=\"mono\">%{IP:source.ip} %{WORD:http.method} %{URIPATHPARAM:http.url}<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-orange\">\n<h3>18) Enrichment<\/h3>\n<p>Enrich logs with GeoIP, ASN, threat intel, or user context. Store enrichments in ECS fields (e.g., <code>geo.*<\/code>, <code>threat.*<\/code>).<\/p>\n<pre><code class=\"mono\">geoip { source =&gt; \"source.ip\" target =&gt; \"source.geo\" }<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-indigo\">\n<h3>19) Pipelines<\/h3>\n<p>Ingest pipelines in Elasticsearch perform transforms before indexing: rename, drop, enrich. Useful for lightweight parsing without Logstash.<\/p>\n<pre><code class=\"mono\">PUT _ingest\/pipeline\/geoip\r\n{ \"processors\":[{ \"geoip\":{ \"field\":\"ip\" } }] }<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-emerald\">\n<h3>20) Q&amp;A \u2014 \u201cWhen use Beats vs Elastic Agent?\u201d<\/h3>\n<p><span class=\"q\">Answer:<\/span> Beats are lightweight and modular but require separate installs. Elastic Agent unifies data + endpoint protection, easier at scale. Use Agent for new deployments, Beats for legacy\/simple needs.<\/p>\n<\/p><\/div>\n<p>      <!-- ===================== SECTION 3 ===================== --><\/p>\n<div class=\"section-title\">Section 3 \u2014 Detection &#038; Response<\/div>\n<div class=\"card bg-blue\">\n<h3>21) Rule Types<\/h3>\n<p>KQL queries, EQL sequences, ML anomaly jobs, and threshold rules. Combine with actions (case, Slack, webhook).<\/p>\n<pre><code class=\"mono\">event.category: authentication and event.outcome: failure<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-green\">\n<h3>22) Prebuilt Rules<\/h3>\n<p>Elastic ships 700+ prebuilt rules (MITRE ATT&#038;CK mapped). Enable, tune thresholds, add exceptions. Update via Detection Rule Repository.<\/p>\n<pre><code class=\"mono\"># Kibana Security \u2192 Detections \u2192 Prebuilt Rules<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-amber\">\n<h3>23) Machine Learning Jobs<\/h3>\n<p>Unsupervised ML jobs detect anomalies (rare processes, unusual logins). Train on baseline and flag deviations. Requires Elastic Platinum license.<\/p>\n<pre><code class=\"mono\"># Example ML detector\r\n\"detector_description\": \"rare process by user\"<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-violet\">\n<h3>24) Alerting &#038; Connectors<\/h3>\n<p>Alerts route to cases, Slack, Jira, ServiceNow, PagerDuty. Connectors define integration endpoints. Manage via Kibana \u2192 Stack Management \u2192 Connectors.<\/p>\n<pre><code class=\"mono\"># Example webhook payload for alert\r\n{ \"alert\":\"High CPU\", \"host\":\"srv1\" }<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-rose\">\n<h3>25) Endpoint Security<\/h3>\n<p>Elastic Agent provides EDR: malware prevention, behaviour monitoring, ransomware protection. Events flow into Security app for analysis.<\/p>\n<pre><code class=\"mono\">elastic-agent install --endpoint-security<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-cyan\">\n<h3>26) Threat Hunting<\/h3>\n<p>Use Timeline to hunt across large datasets. Pivot on IPs, hashes, users. Combine EQL sequences to spot attack chains.<\/p>\n<pre><code class=\"mono\">sequence by user.name\r\n  [authentication where event.outcome == \"failure\"]\r\n  [process where process.name == \"cmd.exe\"]<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-lime\">\n<h3>27) SOAR Workflows<\/h3>\n<p>Automate response with cases + connectors. Example: auto-open Jira ticket on detection, auto-isolate endpoint with Elastic Agent.<\/p>\n<pre><code class=\"mono\">action: isolate endpoint on detection rule trigger<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-orange\">\n<h3>28) MITRE ATT&amp;CK Integration<\/h3>\n<p>Each rule maps to ATT&amp;CK tactics\/techniques. Provides common language for detection coverage. Use dashboards to assess gaps.<\/p>\n<pre><code class=\"mono\">threat.tactic.name: \"Credential Access\"<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-indigo\">\n<h3>29) Case Workflow<\/h3>\n<p>Each case tracks investigation, evidence, notes. Push\/pull to Jira\/ServiceNow. Analysts collaborate and resolve with audit trail.<\/p>\n<pre><code class=\"mono\"># Kibana Security \u2192 Cases \u2192 New Case<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-emerald\">\n<h3>30) Q&amp;A \u2014 \u201cElastic Agent vs EDR vendors?\u201d<\/h3>\n<p><span class=\"q\">Answer:<\/span> Elastic Agent provides EDR integrated with SIEM, reducing vendor sprawl. Dedicated EDR vendors (CrowdStrike, SentinelOne) may offer richer telemetry but cost more.<\/p>\n<\/p><\/div>\n<p>      <!-- ===================== SECTION 4 ===================== --><\/p>\n<div class=\"section-title\">Section 4 \u2014 Operations &#038; Scaling<\/div>\n<div class=\"card bg-blue\">\n<h3>31) Cluster Sizing<\/h3>\n<p>Elastic Security relies on Elasticsearch cluster health. Size for daily ingest (GB\/day), retention, query load. Scale horizontally; use hot-warm-cold tiers.<\/p>\n<pre><code class=\"mono\"># Example sizing: 3 master, N data nodes, 1+ ingest nodes<\/code><\/pre>\n<\/p><\/div>\n<div class=\"card bg-green\">\n<h3>32) Retention &#038; ILM<\/h3>\n<p>Use Index Lifecycle Management (ILM) to roll indices, move to warm\/cold, delete after N days.
