Fixing alert on all hostPaths

[amitschendel]

PR Type:

Bug fix

---

PR Description:

This PR is focused on fixing the alert mechanism for all hostPaths in the system. Previously, the alert was only triggered for hostPaths that started with '/etc' or '/var'. Now, the alert will be triggered for any hostPath, enhancing the security of the system.

---

PR Main Files Walkthrough:

-rules/alert-any-hostpath/raw.rego: The function is_dangerous_host_path was renamed to is_dangerous_volume and its logic was simplified. Instead of checking if the hostPath starts with '/etc' or '/var', it now simply returns the hostPath. This change was also reflected in the deny rules, where is_dangerous_host_path was replaced by is_dangerous_volume.

PR Analysis

• 🎯 Main theme: Fixing a rule to alert on all hostPaths, not only on /var and /etc
• 📌 Type of PR: Bug fix
• 🧪 Relevant tests added: No
• ✨ Focused PR: Yes, because all changes are related to the same rule fix
• 🔒 Security concerns: No, because the changes are related to alerting on hostPaths and do not introduce new security vulnerabilities

PR Feedback

• General suggestions: The PR seems to be fixing a bug in the rule, which is a good improvement. However, it would be better if tests were added to ensure the correctness of the fix. Also, it would be beneficial to add error handling in case the hostPath is not found or is null.

• 🤖 Code feedback:

  • relevant file: rules/alert-any-hostpath/raw.rego
    suggestion: Consider adding null check for volume.hostPath.path to avoid potential null pointer exceptions. [important]
    relevant line: volume.hostPath.path

  • relevant file: rules/alert-any-hostpath/raw.rego
    suggestion: Consider adding a comment explaining the purpose of the function 'is_dangerous_volume' and why it checks for all hostPaths now, not only /var and /etc. This will improve code readability. [medium]
    relevant line: is_dangerous_volume(volume, beggining_of_path, i) = path {
