## Attack Tree Path: [1. Data Exfiltration](./attack_tree_paths/1__data_exfiltration.md)
* **1.1 Unauthorized Access [HR]**
* Description: Gaining access to the InfluxDB instance without proper authorization.
* **1.1.1 Weak Authentication [CN] [HR]**
* Description: Exploiting weak, default, or easily guessable passwords.
* Likelihood: Medium
* Impact: High
* Effort: Low
* Skill Level: Script Kiddie / Beginner
* Detection Difficulty: Medium
* Mitigation:
* Enforce strong password policies.
* Use multi-factor authentication (MFA).
* Regularly audit user accounts and permissions.
* Change default credentials immediately after installation.
* **1.1.2 Guessing/Brute-Force [HR]**
* Description: Attempting to guess credentials through repeated login attempts.
* Likelihood: Medium
* Impact: High
* Effort: Medium
* Skill Level: Beginner / Intermediate
* Detection Difficulty: Medium
* Mitigation:
* Implement account lockout policies.
* Monitor authentication logs.
* Use a Web Application Firewall (WAF) for rate limiting.
* **1.2 Exploiting Vulnerabilities**
* **1.2.1 CVE-XXXX (Known Vulnerability) [HR]**
* Description: Leveraging a publicly known vulnerability (CVE) in InfluxDB to gain unauthorized access.
* Likelihood: Medium
* Impact: High to Very High
* Effort: Low to Medium
* Skill Level: Beginner to Advanced
* Detection Difficulty: Medium to Hard
* Mitigation:
* Regularly update InfluxDB to the latest version.
* Subscribe to security advisories.
* Perform vulnerability scanning.
## Attack Tree Path: [2. Denial of Service (DoS)](./attack_tree_paths/2__denial_of_service__dos_.md)
* **2.1 Resource Exhaustion [HR]**
* Description: Overwhelming the InfluxDB instance with requests, causing it to become unavailable.
* **2.1.1 Query Flood [CN] [HR]**
* Description: Sending a large number of complex or resource-intensive queries.
* Likelihood: High
* Impact: Medium to High
* Effort: Low
* Skill Level: Script Kiddie / Beginner
* Detection Difficulty: Easy
* Mitigation:
* Implement query rate limiting.
* Monitor query performance.
* Optimize database schema and queries.
* Use a WAF to mitigate DDoS attacks.
## Attack Tree Path: [3. Privilege Escalation](./attack_tree_paths/3__privilege_escalation.md)
* **3.2 Configuration Errors [HR]**
* Description: Exploiting misconfigurations in the InfluxDB setup to gain higher privileges.
* **3.2.1 Weak Admin Credentials [CN] [HR]**
* Description: Using weak or default administrator credentials to gain full control.
* Likelihood: Medium
* Impact: Very High
* Effort: Low
* Skill Level: Script Kiddie / Beginner
* Detection Difficulty: Medium
* Mitigation:
* Change default credentials immediately.
* Enforce strong password policies for administrators.
* **3.2.2 Exposed Admin Interface [HR]**
* Description: Accessing the InfluxDB administrative interface that is exposed to untrusted networks.
* Likelihood: Low to Medium
* Impact: Very High
* Effort: Low
* Skill Level: Beginner
* Detection Difficulty: Easy
* Mitigation:
* Restrict access to the administrative interface to trusted networks.
* Use a firewall to block external access.
* Consider using a VPN or SSH tunnel for remote administration.
