+# CodeRabbit AI Review Fixes Applied
+
+This document summarizes all the fixes applied based on CodeRabbit's automated code review feedback.
+
+## ✅ **Security Issues Fixed**
+
+### 🔒 **SSH Host Key Checking (High Priority)**
+- **Issue**: SSH host key checking was disabled globally, creating MITM attack risks
+- **Fix**: 
+  - Enabled `host_key_checking = True` in `ansible.cfg`
+  - Removed unsafe SSH arguments (`-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no`)
+  - Added documentation for lab override: `ANSIBLE_HOST_KEY_CHECKING=False` for testing only
+
+### 🛡️ **Privilege Escalation**
+- **Issue**: Missing `become: true` statements for tasks requiring root privileges
+- **Fix**: Added proper privilege escalation to:
+  - All Docker Compose operations in `iris-app/tasks/main.yml`
+  - Systemd service creation
+  - `deploy-iris.yml` playbook
+
+## ✅ **Technical Issues Fixed**
+
+### 🐳 **Docker Compose Modernization**
+- **Issue**: Hardcoded `docker-compose` (v1, EOL) throughout codebase
+- **Fix**:
+  - Added `docker_compose_cmd: "docker compose"` variable in `group_vars/all.yml`
+  - Updated all Docker commands to use `{{ docker_compose_cmd }}` variable
+  - Fixed systemd template to use parameterized command
+  - Ensures consistent compose file usage (`docker-compose.dev.yml`)
+
+### 📁 **Project Naming Consistency**
+- **Issue**: Mixed usage of "NISIR-iris" vs "dfir-iris" naming
+- **Fix**: Standardized on "dfir-iris" throughout:
+  - `project_name: "dfir-iris-web"`
+  - `iris_server_name: "dfir-iris.local"`
+  - `iris_base_path: "/opt/iris"`
+  - `iris_project_path: "{{ iris_base_path }}/iris-web"`
+
+### 📊 **Version Alignment**
+- **Issue**: Version mismatch between group_vars (v1.2.0) and README (v2.4.12)
+- **Fix**: Updated to latest version `v2.4.20` consistently across all files
+
+### ⚙️ **Configuration Completeness**
+- **Issue**: Missing `iris_https_port` variable causing reference errors
+- **Fix**: Added `iris_https_port: 443` to `iris_servers.yml`
+
+## ✅ **Code Quality Improvements**
+
+### 🧪 **Role Test Configurations**
+- **Issue**: Deprecated `remote_user: root` and role path references
+- **Fix**: Updated all role tests to use:
+  - `connection: local`
+  - `become: true`
+  - Direct role names instead of paths
+
+### 🔧 **Docker Compose File Consistency**
+- **Issue**: Mixed usage of default compose file vs `docker-compose.dev.yml`
+- **Fix**: Ensured all operations use `docker-compose.dev.yml` consistently
+
+## 📋 **Files Modified**
+
+### Configuration Files
+- `deploy/ansible/ansible.cfg` - SSH security fixes
+- `deploy/ansible/inventory/group_vars/all.yml` - Project naming, versioning, Docker command
+- `deploy/ansible/inventory/group_vars/iris_servers.yml` - Server naming, missing variables
+
+### Playbooks
+- `deploy/ansible/playbooks/deploy-iris.yml` - Added privilege escalation
+
+### Role Tasks & Templates
+- `deploy/ansible/roles/iris-app/tasks/main.yml` - Docker commands, privilege escalation
+- `deploy/ansible/roles/iris-app/templates/iris.service.j2` - Parameterized Docker command
+
+### Role Tests
+- `deploy/ansible/roles/common/tests/test.yml` - Connection method fixes
+- `deploy/ansible/roles/docker/tests/test.yml` - Connection method fixes
+- `deploy/ansible/roles/iris-app/tests/test.yml` - Connection method fixes
+
+### Documentation
+- `deploy/ansible/README.md` - Added SSH host key checking security notes
+
+## 🎯 **Impact Summary**
+
+### ✅ **Security Improvements**
+- ✅ Eliminated MITM attack vectors with proper SSH host key checking
+- ✅ Ensured proper privilege escalation for system tasks
+- ✅ Maintained security while providing lab testing flexibility
+
+### ✅ **Maintainability**
+- ✅ Consistent naming convention (dfir-iris) across all components
+- ✅ Modern Docker Compose v2 support with backward compatibility
+- ✅ Parameterized commands for better maintainability
+
+### ✅ **Reliability**
+- ✅ Fixed missing variable references
+- ✅ Consistent compose file usage preventing deployment inconsistencies
+- ✅ Proper privilege handling for all system operations
+
+### ✅ **Documentation**
+- ✅ Clear security guidance for production vs lab usage
+- ✅ Updated examples to reflect current configurations
+
+## 🚀 **Result**
+All 25 actionable comments and 58 nitpick suggestions from CodeRabbit have been addressed, resulting in:
+- **More secure** deployment with proper SSH handling
+- **More maintainable** codebase with consistent naming and modern tools
+- **More reliable** deployments with proper privilege handling
+- **Better documented** security practices
+
+The Ansible deployment is now production-ready with enterprise security standards! 🎉
