Features
<div align="center"> <br> <img src="assets/matano_athena.png" width="650"> </div> <br>- Security Data Lake: Normalize unstructured security logs into a structured realtime data lake in your AWS account.
- Collect All Your Logs: Integrates out of the box with 50+ sources for security logs and can easily be extended with custom sources.
- Detection-as-Code: Use Python to build realtime detections as code. Support for automatic import of Sigma detections to Matano.
- Log Transformation Pipeline: Supports custom VRL (Vector Remap Language) scripting to parse, enrich, normalize and transform your logs as they are ingested without managing any servers.
- No Vendor Lock-In: Uses an open table format (Apache Iceberg) and open schema standards (ECS), to give you full ownership of your security data in a vendor-neutral format.
- Bring Your Own Analytics: Query your security lake directly from any Iceberg-compatible engine (AWS Athena, Snowflake, Spark, Trino etc.) without having to copy data around.
- Serverless: Fully serverless and designed specifically for AWS and focuses on enabling high scale, low cost, and zero-ops.
Architecture
<div align="center"> <br> <img src="assets/diagram.png" width="600"> </div>👀 Use cases
- Reduce SIEM costs.
- Augment your SIEM with a security data lake for additional context during investigations.

Quick start
View the complete installation instructions
Installation
Install the matano CLI to deploy Matano into your AWS account, and manage your deployment.
Linux
curl -OL https://github.com/matanolabs/matano/releases/download/nightly/matano-linux-x64.sh
chmod +x matano-linux-x64.sh
sudo ./matano-linux-x64.sh
macOS
curl -OL https://github.com/matanolabs/matano/releases/download/nightly/matano-macos-x64.sh
chmod +x matano-macos-x64.sh
sudo ./matano-macos-x64.sh
Deployment
Read the complete docs on getting started
To get started, run the matano init
command.
- Make sure you have AWS credentials in your environment (or in an AWS CLI profile).
- The interactive CLI wizard will walk you through getting started by generating an initial Matano directory for you, initializing your AWS account, and deploying into your AWS account.
- Initial deployment takes a few minutes.
Directory structure
Once initialized, your Matano directory is used to control & manage all resources in your project e.g. log sources, detections, and other configuration. It is structured as follows:
➜ example-matano-dir git:(main) tree
├── detections
│ └── aws_root_credentials
│ ├── detect.py
│ └── detection.yml
├── log_sources
│ ├── cloudtrail
│ │ ├── log_source.yml
│ │ └── tables
│ │ └── default.yml
│ └── zeek
│ ├── log_source.yml
│ └── tables
│ └── dns.yml
├── matano.config.yml
└── matano.context.json
When onboarding a new log source or authoring a detection, run matano deploy
from anywhere in your project to deploy the changes to your account.
🔧 Log Transformation & Data Normalization
Read the complete docs on configuring custom log sources
Vector Remap Language (VRL), allows you to easily onboard custom log sources and encourages you to normalize fields according to the Elastic Common Schema (ECS) to enable enhanced pivoting and bulk search for IOCs across your security data lake.
Users can define custom VRL programs to parse and transform unstructured logs as they are being ingested through one of the supported mechanisms for a log source (e.g. S3, SQS).
VRL is an expression-oriented language designed for transforming observability data (e.g. logs) in a safe and performant manner. It features a simple syntax and a rich set of built-in functions tailored specifically to observability use cases.
Example: parsing JSON
Let's have a look at a simple example. Imagine that you're working with HTTP log events that look like this:
{
"line": "{\"status\":200,\"srcIpAddress\":\"1.1.1.1\",\"message\":\"SUCCESS\",\"username\":\"ub40fan4life\"}"
}
You want to apply these changes to each event:
- Parse the raw
line
string into JSON, and explode the fields to the top level - Rename
srcIpAddress
to thesource.ip
ECS field - Remove the
username
field - Convert the
message
to lowercase
Adding this VRL program to your log source as a transform
step would accomplish all of that:
log_source.yml
transform: |
. = object!(parse_json!(string!(.json.line)))
.source.ip = del(.srcIpAddress)
del(.username)
.message = downcase(string!(.message))
schema:
ecs_field_names:
- source.ip
- http.status
The resulting event 🎉:
{
"message": "success",
"status": 200,
"source": {
"ip": "1.1.1.1"
}
}
📝 Writing Detections
Read the complete docs on detections
Use detections to define rules that can alert on threats in your security logs. A detection is a Python program that is invoked with data from a log source in realtime and can create an alert.
Examples
Detect failed attempts to export AWS EC2 instance in AWS CloudTrail logs.
def detect(record):
return (
record.deepget("event.action") == "CreateInstanceExportTask"
and record.deepget("event.provider") == "ec2.amazonaws.com"
and record.deepget("event.outcome") == "failure"
)
Detect Brute Force Logins by IP across all configured log sources (e.g. Okta, AWS, GWorkspace)
detect.py
def detect(r):
return (
"authentication" in r.deepget("event.category", [])
and r.deepget("event.outcome") == "failure"
)
def title(r):
return f"Multiple failed logins from {r.deepget('user.full_name')} - {r.deepget('source.ip')}"
def dedupe(r):
return r.deepget("source.ip")
detection.yml
---
tables:
- aws_cloudtrail
- okta_system
- o365_audit
alert:
severity: medium
threshold: 5
deduplication_window_minutes: 15
destinations:
- slack_my_team
Detect Successful Login from never before seen IP for User
from detection import remotecache
# a cache of user -> ip[]
user_to_ips = remotecache("user_ip")
def detect(record):
if (
record.deepget("event.action") == "ConsoleLogin" and
record.deepget("event.outcome") == "success"
):
# A unique key on the user name
user = record.deepget("user.name")
existing_ips = user_to_ips[user] or []
updated_ips = user_to_ips.add_to_string_set(
user,
record.deepget("source.ip")
)
# Alert on new IPs
new_ips = set(updated_ips) - set(existing_ips)
if existing_ips and new_ips:
return True
🚨 Alerting
Read the complete docs on alerting
Alerts table
All alerts are automatically stored in a Matano table named matano_alerts
. The alerts and rule matches are normalized to ECS and contain context about the original event that triggered the rule match, along with the alert and rule data.
Example Queries
Summarize alerts in the last week that are activated (exceeded the threshold)
select
matano.alert.id as alert_id,
matano.alert.rule.name as rule_name,
max(matano.alert.title) as title,
count(*) as match_count,
min(matano.alert.first_matched_at) as first_matched_at,
max(ts) as last_matched_at,
array_distinct(flatten(array_agg(related.ip))) as related_ip,
array_distinct(flatten(array_agg(related.user))) as related_user,
array_distinct(flatten(array_agg(related.hosts))) as related_hosts,
array_distinct(flatten(array_agg(related.hash))) as related_hash
from
matano_alerts
where
matano.alert.first_matched_at > (current_timestamp - interval '7' day)
and matano.alert.activated = true
group by
matano.alert.rule.name,
matano.alert.id
order by
last_matched_at desc
Delivering alerts
You can deliver alerts to external systems. You can use the alerting SNS topic to deliver alerts to Email, Slack, and other services.
