Enterprise Recon 2.0.31
You can use ER2 to perform an agentless scan on network Targets via a Proxy Agent. Agentless scans allow you to perform a scan on a target system without having to:
- Install a Node Agent on the Target host, and
- Transmit sensitive information over the network to scan it.
Use agentless scans when:
- The Node Agent is installed on a host other than the Target host.
- Data transmitted over the network must be kept to a minimum.
- The Target credential set has the required permissions to read, write and execute on the Target host.
- The Target host security policy has been configured to allow the scanning engine to be executed locally.
For more information, see Agentless Scan Requirements below.
How an Agentless Scan Works
When an agentless scan starts, the Proxy Agent receives instructions from the Master Server to perform a scan on a Target host. Once a secure connection to the Target host has been established, the Proxy Agent copies the latest version of the scanning engine to a temporary location on the Target host.
The scanning engine is then run on the Target host. It scans the local system and sends aggregated results to the Proxy Agent, which in turn sends the results to the Master Server. Data scanned by ER2 is kept within the Target host. Only a summary of found matches is sent back to the Master Server.
Once the scan completes, the Proxy Agent cleans up temporary files created on the Target host during the scan and closes the connection.
Agentless Scan Requirements
Make sure that the Target and Proxy Agent host fulfill the following requirements:
|Target Host||Proxy Agent||TCP Port 1||Requirements|
|Windows host||Windows Proxy Agent||
For Targets running Windows Server 2008 and newer:
For Targets running Windows Server 2003 R2 and older:
WMI can be configured to use static ports instead of dynamic ports.
|Unix or Unix-like host||Windows or Unix Proxy Agent||
1 TCP Port allowed connections.
Before embarking on this approach, Ground Labs recommends consideration of the Agent-based scanning approach which can achieve data discovery with a reduced level of user permission whilst offering other performance benefits.
Start an Agentless Scan
To perform an agentless scan on a Target:
Expand the navigation menu, ENTERPRISE RECON .
- In DASHBOARD, TARGETS, or SCHEDULE MANAGER, click Start Search.
- On the Select Locations page, click + Add Unlisted Target.
- In the Select Target Type window, choose Server and enter the host name of the Target in the Enter New Target Hostname field.
- Click Test. If ER2 can connect to the Target, the button changes to a Commit button.
- In the Select Types dialog box, select Target locations from Local Storage or Local Process Memory and click Next.
- In the Setup Targets page, assign the new Target to a Target Group, and select the operating system for the Target.
- The UI prompts you if there is no usable Agent detected on the Target host. Select Would you like to search this target without installing an agent on it? to continue.
Fill in the following fields and click Next:
Field Description Credential Label Enter a descriptive label for the credential set. Username Enter your Target host user name. Password Enter your Target host user password. (Optional) Private Key Upload the file containing the private key.
Only required for Target hosts that use a public key-based authentication method.
Agent to act as proxy host Select a suitable Proxy Agent.
- On the Select Data Types page, select the Data Type Profiles to be included in your scan and click Next. See Data Type Profiles.
- Set a scan schedule in the Set Schedule section. Click Next.
- Review your scan configuration. Once done, click Start Scan.
