Cisco Secure Access - Web

Overview

The Cisco Secure Access Web logs show your organization's traffic through the Secure Access proxy.

  • Vendor: Cisco
  • Supported environment: Cloud
  • Detection based on: Telemetry

Warning

Important note - This format is currently in beta. We highly value your feedback to improve its performance.

Configure

This section will guide you through configuring Cisco Secure Access to forward logs to Sekoia.io using a Cisco-managed Amazon S3 bucket.

Prerequisites

  • Full Admin user role in Cisco Secure Access. For more information, see the Manage Accounts documentation.
  • Access to Sekoia.io Intakes and Playbook pages with write permissions.

Step 1 — Configure the Cisco-Managed S3 Bucket

Cisco Secure Access can export your logs to a Cisco-managed Amazon S3 bucket. Cisco configures all managed buckets to use Amazon Server-Side Encryption with S3-Managed Keys (SSE-S3, AES-256). Access is provided via AWS IAM credentials.

  1. In the Cisco Secure Access dashboard, navigate to Admin > Log Management.
  2. Click Set up cloud storage and select Cisco.

  3. Select a Region — choose the region closest to you to minimize latency when downloading logs.

    Warning

    The selected region cannot be changed later without deleting your current settings and starting over. Not all AWS regions are available.

  4. Select a Retention Duration — choose 7, 14, or 30 days.

    Note

    Beyond the selected time period, all data is purged and cannot be retrieved. A shorter duration is recommended if your ingestion cycle is frequent.

  5. Click Save. Cisco Secure Access activates log export to the S3 bucket. When activation is complete, the Amazon S3 Summary page appears.

  6. Copy the Access Key and Secret Key and store them in a safe place.

    Warning

    The Access Key and Secret Key are displayed only once. If you lose them, you must regenerate them by rotating the keys in Cisco Secure Access.

  7. Click Done.

Step 2 — Create the Intake

Configure Your Intake

This section will guide you through creating the intake object in Sekoia, which provides a unique identifier called the "Intake key." The Intake key is essential for later configuration, as it references the Community, Entity, and Parser (Intake Format) used when receiving raw events on Sekoia.

  1. Go to the Sekoia Intake page.
  2. Click on the + New Intake button at the top right of the page.
  3. Search for your Intake by the product name in the search bar.
  4. Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
  5. Click on Create.

Note

For more details on how to use the Intake page and to find the Intake key you just created, refer to this documentation.

Step 3 — Configure the Connector

Configure Your Playbook

This section will assist you in pulling remote logs from Sekoia and sending them to the intake you previously created.

  1. Go to the Sekoia playbook page.
  2. Click on the + New playbook button at the top right of the page.
  3. Select Create a playbook from scratch, and click Next.
  4. Give it a Name and a Description, and click Next.
  5. Choose a trigger from the list by searching for the name of the product, and click Create.
  6. A new Playbook page will be displayed. Click on the module in the center of the page, then click on the Configure icon.
  7. On the right panel, click on the Configuration tab.
  8. Select an existing Trigger Configuration (from the account menu) or create a new one by clicking on + Create new configuration.
  9. Configure the Trigger based on the Actions Library (for instance, see here for AWS modules), then click Save.
  10. Click on Save at the top right of the playbook page.
  11. Activate the playbook by clicking on the "On / Off" toggle button at the top right corner of the page.

When selecting the trigger, choose Fetch new logs on S3 (without SQS).

Before configuring the connector, retrieve the Data path from the Cisco Secure Access Amazon S3 Summary page. It looks like this:

s3://cisco-managed-eu-central-1/1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0

From this path:

  • the bucket name is the first segment after s3:// — here, cisco-managed-eu-central-1.
  • the base prefix is the second segment — here, 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0. Cisco stores each log type in a dedicated subfolder under this prefix.

In the connector configuration, set the following fields:

  • AWS Region (aws_region_name): the region you selected when configuring the S3 bucket in Cisco Secure Access (for example, eu-central-1).
  • AWS Access Key (aws_access_key): the Access Key copied from the Cisco Secure Access Amazon S3 Summary page.
  • AWS Secret Access Key (aws_secret_access_key): the Secret Key copied from the Cisco Secure Access Amazon S3 Summary page.
  • Bucket (bucket): the bucket name extracted from the Data path (for example, cisco-managed-eu-central-1).
  • Prefix filter (prefix_filter): the base prefix followed by the subfolder matching the log type you want to collect. Since the bucket holds several log types, this filter ensures the connector only ingests the logs for this intake.
  • Intake key (intake_key): the intake key generated when you created the intake in Step 2.

Cisco Secure Access stores each log type in a dedicated subfolder under the base prefix. Set the Prefix filter to <base_prefix>/<subfolder>, using the subfolder that matches the intake you are configuring:

Intake Subfolder Example prefix filter
Cisco Secure Access - DNS dnslogs 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0/dnslogs
Cisco Secure Access - Web proxylogs 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0/proxylogs
Cisco Secure Access - Cloud Firewall firewalllogs 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0/firewalllogs
Cisco Secure Access - IPS intrusionlogs 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0/intrusionlogs
Cisco Secure Access - File Events fileeventlogs 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0/fileeventlogs

Note

Replace 1234567_a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0 with the base prefix extracted from your own Cisco Secure Access Data path.

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.

No related built-in rules was found. This message is automatically generated.
