Incident Response in On-Premises Environments
On-premises environments consist of physical servers, local networks, and endpoints managed directly by an organization. These setups are highly customizable but also require proactive measures to handle incidents.
Key Steps:
- Asset Inventory Management: Maintaining a detailed inventory of all hardware and software assets to identify potential vulnerabilities.
- Network Segmentation: Isolating sensitive areas of the network to prevent lateral movement of threats during an incident.
- Log Analysis: Reviewing logs from firewalls, intrusion detection/prevention systems (IDS/IPS), and endpoint devices to identify anomalies.
- Patch Management: Ensuring timely updates to all systems to close known vulnerabilities.
- Backup and Recovery: Storing offline backups to ensure that systems can be restored quickly after an attack, such as ransomware.
Common Challenges:
- Lack of real-time visibility across all devices.
- The need for manual processes in older legacy systems.
