Cloudflare Audit Logs
Overview
Cloudflare is a global network designed to make everything you connect to the Internet secure, private, fast, and reliable. In this documentation, you will learn how to collect and send Cloudflare Audit logs to Sekoia.io.
- Vendor: Cloudflare
- Supported environment: SaaS
- Detection based on: Telemetry
- Supported application or feature: Web application firewall logs
Configuration
Create the intake on Sekoia.io
Go to the intake page and create a new intake from the format Cloudflare.
Configure events forwarding on Cloudflare
Retrieve necessary information
First, you will have to retrieve configuration information. Connect to Cloudflare Console to collect the following :
-
Cloudflare API Token
- Go to
My Profile, then on the left panel, click onAPI Tokens. - Click on the
Create Tokenbutton and select theCreate Custom Tokenentry. - Give a name to your token and set the following permissions:
Scope Group Level Account Account Analytics Read Account Logs Read Account Logs Edit Zone Logs Read Zone Logs Edit - If you want zerotrust logs you should also add:
Scope Group Level Account Zero Trust Read - Go to
-
Cloudflare Zone ID :
- This information is specific to a Website.
- On the left panel, click on
Websitesand select the Website you want. - On the right panel, there is an
APIsection where you can retrieve theZone ID.
Create a Logpush job
Configure a Logpush job with the following destination:
https://intake.sekoia.io/plain/batch?header_X-SEKOIAIO-INTAKE-KEY=<YOUR_INTAKE_KEY>
To do so, you can manage Logpush with cURL:
$ curl -X POST 'https://api.cloudflare.com/client/v4/accounts/<CLOUDFLARE_ACCOUNT_ID>/logpush/jobs' \
-H 'Authorization: Bearer <CLOUDFLARE_API_TOKEN>' \
-H "Content-Type: application/json" \
-d '{
"dataset": "audit_logs",

"max_upload_records": 1000,
"logpull_options":"fields=ActionResult,ActionType,ActorEmail,ActorID,ActorIP,ActorType,ID,Interface,Metadata,NewValue,OldValue,OwnerID,ResourceID,ResourceType,When×tamps=rfc3339",
"destination_conf": "https://intake.sekoia.io/plain/batch?header_X-SEKOIAIO-INTAKE-KEY=<YOUR_INTAKE_KEY>"
}' # (1)
- will return

Important
Replace :
<YOUR_INTAKE_KEY>with the Intake key you generated in the Create the intake on Sekoia.io step.<CLOUDFLARE_ACCOUNT_ID>with the ACCOUNT_ID found on the overview page<CLOUDFLARE_API_TOKEN>with the API Token you generated
Useful Cloudflare API endpoints
On their documentation, Cloudflare provides a list API endpoints you can use. Find below some useful endpoints:
https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/logpush/jobs/<JOB_ID>to verify the job you previously created is correct (you need to specify theJOB_ID)https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/logpush/datasets/<DATASET>/jobsto get all the jobs for a specific dataset (dns_log,firewalls_eventsorhttp_requestsin our case)https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/logpush/jobs/<JOB_ID>to update a job if you noticed a mistake after the creation of the job (wrong fields, wrong SEKOIA API Key...)
Raw Events Samples
In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

Detection section
The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.
Related Built-in Rules
The following Sekoia.io built-in rules match the intake Cloudflare Audit logs. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.
SEKOIA.IO x Cloudflare Audit logs on ATT&CK Navigator
Cryptomining
Detection of domain names potentially related to cryptomining activities.
- Effort: master
Dynamic DNS Contacted
Detect communication with dynamic dns domain. This kind of domain is often used by attackers. This rule can trigger false positive in non-controlled environment because dynamic dns is not always malicious.
- Effort: master
Exfiltration Domain
Detects traffic toward a domain flagged as a possible exfiltration vector.
- Effort: master
Remote Access Tool Domain
Detects traffic toward a domain flagged as a Remote Administration Tool (RAT).
- Effort: master
SEKOIA.IO Intelligence Feed
Detect threats based on indicators of compromise (IOCs) collected by SEKOIA's Threat and Detection Research team.
- Effort: elementary
Sekoia.io EICAR Detection
Detects observables in Sekoia.io CTI tagged as EICAR, which are fake samples meant to test detection.
- Effort: master
TOR Usage Generic Rule
Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works. TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.
- Effort: master
Event Categories
The following table lists the data source offered by this integration.
| Data Source | Description |
|---|---|
Authentication logs |
Cloudflare Access logs an authentication event whenever a user or service attempts to log in to an application, whether the attempt succeeds or not. |
In details, the following table denotes the type of events produced by this integration.
| Name | Values |
|---|---|
| Kind | `` |
| Category | network |
| Type | access |
Transformed Events Samples after Ingestion
This section demonstrates how the raw logs will be transformed by our parsers. It shows the extracted fields that will be available for use in the built-in detection rules and hunting activities in the events page. Understanding these transformations is essential for analysts to create effective detection mechanisms with custom detection rules and to leverage the full potential of the collected data.
