AI Ethics
- AI Ethics Server Configuration
This article details the server configuration specifically designed to support the "AI Ethics" project on our MediaWiki platform. This setup focuses on providing sufficient computational resources and a secure environment for discussions, documentation, and research related to the ethical implications of Artificial Intelligence. This guide is intended for newcomers to the server administration side of the wiki.
Overview
The AI Ethics project requires significant server capacity due to the potential for large datasets, complex discussions, and the need for robust security measures. This configuration prioritizes stability, scalability, and data integrity. It leverages a dedicated server cluster with specialized hardware and software components. We will cover hardware specifications, software stack, security considerations, and ongoing maintenance procedures. This configuration builds upon our existing Server Infrastructure Overview and is integrated with the Data Backup Procedures.
Hardware Specifications
The AI Ethics project utilizes a dedicated cluster of three servers, each with the following specifications:
| Component | Specification | |
|---|---|---|
| CPU | 2 x Intel Xeon Gold 6248R (24 cores per CPU, 3.0 GHz) | |
| RAM | 256 GB DDR4 ECC Registered RAM | |
| Storage | 4 x 4TB NVMe SSD (RAID 10) for OS and application data | 8 x 16TB SAS HDD (RAID 6) for long-term data storage and backups |
| Network Interface | 2 x 10 Gigabit Ethernet | |
| Power Supply | Redundant 1600W Platinum Power Supplies |
These specifications ensure sufficient processing power, memory, and storage capacity to handle the demands of the AI Ethics project. The RAID configurations provide data redundancy and fault tolerance. Refer to Hardware Procurement Policy for details on equipment selection.
Software Stack
The software stack is configured to optimize performance and security for the AI Ethics project.
| Software | Version | Purpose |
|---|---|---|
| Operating System | Ubuntu Server 22.04 LTS | Provides a stable and secure base operating system. |
| Web Server | Apache 2.4 | Handles HTTP requests and serves wiki content. Configured according to Apache Configuration Standards. |
| Database Server | MariaDB 10.6 | Stores wiki content and metadata. Optimized for performance (see Database Optimization Guide). |
| PHP | 8.1 | Executes wiki code and interacts with the database. Configured with appropriate extensions (see PHP Extension Management). |
| MediaWiki | 1.40 | The core wiki software. Configured with custom extensions for AI Ethics project features. |
| Fail2Ban | 0.11 | Intrusion prevention framework. |
The use of LTS versions ensures long-term support and stability. Regular software updates are applied according to the Security Patching Schedule.
Security Considerations
Security is paramount for the AI Ethics project, given the sensitive nature of the discussions and data involved. We employ a multi-layered security approach:
- Firewall Configuration: A robust firewall (ufw) is configured to restrict network access to essential ports only. See Firewall Management Protocol.
- Intrusion Detection System (IDS): Fail2Ban is used to monitor for and block malicious activity.
- Regular Security Audits: Periodic security audits are conducted to identify and address vulnerabilities. Follow Security Audit Checklist.
- Data Encryption: All sensitive data is encrypted both in transit (HTTPS) and at rest.
- Access Control: Strict access control policies are enforced to limit access to sensitive data and system resources.
- User Authentication: Strong password policies and two-factor authentication are enforced for all users. Refer to User Account Security.
- MediaWiki Security Extensions: We utilize several MediaWiki security extensions such as AbuseFilter and TitleBlacklist.
Monitoring and Maintenance
Continuous monitoring and proactive maintenance are essential for ensuring the long-term stability and performance of the AI Ethics server cluster.
| Monitoring Tool | Metrics Monitored |
|---|---|
| Nagios | CPU Usage, Memory Usage, Disk Space, Network Traffic, Database Performance |
| Prometheus | System Resource Utilization, Application Performance, Custom Metrics |
| Logwatch | System Logs, Application Logs, Security Logs |
We perform regular backups of the wiki database and files according to the Data Backup Procedures. Scheduled maintenance windows are used to apply software updates, perform hardware maintenance, and optimize system performance. See Scheduled Maintenance Calendar. The Incident Response Plan outlines procedures for handling security incidents and system failures. The team regularly reviews Server Performance Metrics.
Integration with Other Systems
This server cluster is integrated with other systems on our network, including:
- Central Authentication System : For user authentication.
- Content Delivery Network (CDN) : For improved content delivery.
- Logging and Monitoring Infrastructure : For centralized log management and monitoring.
