Docker Cheat Sheet: OSINT

Open Source Intelligence (OSINT) is the practice of gathering and analyzing publicly available information from various sources to support intelligence or security operations. In the context of Docker, OSINT can be used to gather information about a container's environment, network, and other relevant details.

Tools Used in OSINT for Docker

The following tools can be used to perform OSINT on Docker containers:

• Nmap: A network scanning tool that can be used to discover open ports and services running within a container.
• Netcat: A networking utility that can be used to establish connections and transfer data between hosts, including between a host and a container.
• Psutil: A cross-platform Python library for retrieving information on running processes and system utilization in real-time.

OSINT Techniques for Docker

The following OSINT techniques can be used to gather information about a Docker container:

• IP Address Scanning: Use tools like Nmap to scan the IP address range associated with a container's network interface to determine open ports and services.
• Port Scanning: Use tools like Netcat to establish connections to open ports within a container to gather information about running services.
• Process List: Use tools like Psutil to retrieve a list of running processes within a container, which can be used to identify potential vulnerabilities or suspicious activity.

Docker Container Analysis

A Docker container's configuration and runtime environment can provide valuable information for OSINT operations. The following elements can be analyzed:

• Image Inspection: Use tools like Docker inspect to retrieve detailed information about a container's image, including its layers, dependencies, and configuration.
• Network Configuration: Analyze the container's network configuration using tools like Docker network inspect or nmap.
• Process List: Retrieve a list of running processes within the container using tools like Psutil or Docker exec.

Best Practices for OSINT in Docker

The following best practices can be used to ensure effective and efficient OSINT operations with Docker:

• Use authorized tools: Only use tools that are specifically designed for OSINT operations, as unauthorized tool usage can compromise the integrity of your findings.
• Respect privacy: Ensure that you have the necessary permissions and follow relevant laws and regulations when gathering information about individuals or organizations.
• Document and analyze: Document all findings thoroughly and analyze them to identify potential security risks or vulnerabilities.
