    • 1.3.1. Identify Misconfigured Supervisor:

      • Description: Attacker scans for and identifies Supervisors deployed with weak security settings. This could include:
        • Exposed Supervisor API without proper authentication or authorization.
        • Usage of default or weak credentials for Supervisor access.
        • Insecure communication protocols (e.g., unencrypted HTTP instead of HTTPS).
      • Likelihood: Medium to High (Misconfigurations are common, especially in initial deployments or rapid setups).
      • Impact: Medium to High (Unauthorized access to Supervisor control plane, potentially leading to control over managed services).
      • Mitigation:
        • Follow Habitat's security best practices for Supervisor configuration.
        • Enforce strong authentication and authorization for Supervisor API access.
        • Disable or restrict access to the Supervisor API from untrusted networks.
        • Use HTTPS for all Supervisor API communication.
        • Regularly audit Supervisor configurations for security weaknesses.

    • 1.3.2. Leverage Misconfiguration for Unauthorized Access/Control:

        • Configuration data transmitted over unencrypted channels (e.g., HTTP).
        • Lack of access controls on configuration storage locations.
      • Likelihood: Medium to High (Insecure practices are common, especially in development environments or quick deployments).
      • Impact: Medium (Exposure of sensitive configuration data, potentially including secrets).
      • Mitigation:
        • Encrypt sensitive configuration data at rest and in transit.
        • Store configuration files in secure locations with appropriate access controls (e.g., restricted file system permissions).
        • Use HTTPS or other secure protocols for transmitting configuration data to Supervisors.
        • Regularly audit configuration storage and transmission practices for security weaknesses.

    • 3.2.2. Intercept or Access Configuration Data:

      • Description: Attacker intercepts configuration data during transmission or gains unauthorized access to configuration storage locations. This could involve:
        • Network sniffing to intercept unencrypted configuration data.
        • Exploiting file system vulnerabilities or misconfigurations to access configuration files.
        • Using compromised credentials to access configuration storage.
      • Likelihood: High (If insecure storage/transmission exists, access/interception is likely).
      • Impact: N/A (Step towards data exposure).
      • Mitigation:
        • Secure configuration storage and transmission as described in 3.2.1 mitigation.
        • Implement network segmentation to limit exposure of configuration traffic.
        • Monitor access to configuration storage locations for unauthorized activity.

    • 3.2.3. Extract Sensitive Information or Modify Configuration for Malicious Purposes:

      • Description: Once configuration data is accessed, the attacker extracts sensitive information (e.g., secrets, credentials) or modifies the configuration for malicious purposes. This could include:
        • Stealing credentials to gain unauthorized access to other systems.
        • Modifying application settings to inject backdoors or malicious code.
        • Disrupting application functionality by altering configuration parameters.
      • Likelihood: High (If configuration data is accessed, extraction/modification is likely).
      • Impact: Medium to High (Credential theft, application compromise, data breach, service disruption).
      • Mitigation:
        • Secure configuration data and access as described in 3.2.1 and 3.2.2 mitigations.
        • Implement secrets management solutions to avoid storing secrets directly in configuration files.
        • Monitor configuration changes for unauthorized modifications.

Attack Tree Path: 3.3. Exposed Secrets in Habitat Configuration [HIGH-RISK PATH] [CRITICAL NODE]:

Attack Vector: Secrets (e.g., passwords, API keys) are directly embedded in Habitat configuration files.

  • Breakdown:

    • 3.3.1. Secrets are Stored Directly in Habitat Configuration:

      • Description: Developers or operators mistakenly store sensitive secrets directly within Habitat configuration files, often in plain text. This is a common anti-pattern.
      • Likelihood: Medium to High (Common mistake, especially in development or quick setups, or due to lack of security awareness).
      • Impact: Medium to High (Exposure of sensitive credentials, leading to unauthorized access).
      • Mitigation:
        • Never store secrets directly in configuration files.
        • Use dedicated secrets management solutions (e.g., HashiCorp Vault, Kubernetes Secrets) to store and manage secrets securely.
        • Utilize environment variables to pass secrets to applications at runtime, instead of embedding them in configuration.
        • Implement code reviews and security audits to identify and remove any hardcoded secrets.

    • 3.3.2. Access Habitat Configuration:

      • Description: Attacker gains access to Habitat configuration files where secrets are stored. This could be through:
        • Exploiting Supervisor API vulnerabilities or misconfigurations.
        • Gaining unauthorized file system access to Supervisor hosts.
        • Compromising accounts with access to configuration repositories.
      • Likelihood: Medium to High (Depending on Supervisor API security, file system permissions, and access control practices).
      • Impact: N/A (Step towards secret exposure).
      • Mitigation:
        • Secure Supervisor API and file system access as described in previous sections.
        • Implement robust access controls for configuration repositories.
        • Encrypt configuration data at rest.

    • 3.3.3. Extract and Abuse Exposed Secrets:

      • Likelihood: High (If secrets are exposed and accessible, abuse is likely).
      • Impact: Medium to High (Unauthorized access to critical systems, data breaches, depending on the nature of the exposed secrets).
      • Mitigation:
        • Prevent secrets from being stored in configuration files as described in 3.3.1 mitigation.
        • If secrets are accidentally exposed, immediately revoke and rotate them.
        • Implement monitoring and alerting for suspicious account usage and API access that might indicate compromised credentials.
