- Security events like dropped connections, access denials, quarantined files, and more.
- System events like device configuration changes, reboots, HA failovers, etc.
- Various alerts and alarms for critical issues.
- Log reports allow for the analysis of historical trends to spot anomalies.
Track Threat Activity
Administrators can monitor in real-time:
- Top sources of threats like malware domains, botnet IPs, geographic hotspots, etc.
- Hacked internal hosts contacting command and control centers.
- Most targeted assets and applications in the environment.
This enables quickly identifying and responding to active attacks against the network.
Configure Alerting for Key Events
Alerts can automatically inform administrators of critical events through email, SMS, and more. These events may include:
- Security policy violations by high-risk applications or events.
- Abnormal traffic spikes that indicate a DDoS attack.
- Hardware failures like power supplies or fans.
- Log storage is reaching full capacity.
Managing Cisco Firewalls Remotely
Centralized management platforms like Cisco Firepower Management Center and Meraki Dashboards provide the basis for remotely handling devices via a single interface. This makes the following management possible:
Firewall Policies and Configurations
Administrators can use management platforms to remotely:
- Add new firewall rules and modify existing rules to improve access controls.
- Adjust VPN parameters as needed for improved performance.
- Update NAT configuration as the network changes.
- Push new firmware versions to maintain up-to-date security.
Security Content Updates
Remote management allows quick installation of newly released:
- Intrusion rule signatures to detect emerging threats.
- URL category and reputation data to block newly identified malicious sites.
- IP and domain blacklists to block malware and spam.
Compliance Reporting and Audits
Centralized management provides reports to confirm compliance with standards like PCI-DSS, HIPAA, etc.
Backup and Recovery
Critical firewall data like configs, logs, and software images can be regularly backed up to remote servers. This enables recovery after failures.
Central Policy Management
Management systems like Firepower MC let you create a single master firewall rule set that propagates to all of the firewalls. This prevents configuration changes across the network.
Best Practices for Remote Management
Some tips for effective remote monitoring and management include the following:
- Define strong admin passwords and use multi-factor authentication for management access.
- Limit read-write access to a small team and use read-only accounts for monitoring to limit exposure.
- Encrypt management channels using HTTPS/SSL and disable insecure protocols.
- Restrict management access to authorized management networks only.
- Regularly backup firewall configurations and software images to external, secure storage.
- Use multiple management servers and firewall power supplies for high availability.
Solid remote monitoring and management capabilities allow security teams to securely configure firewalls, respond to threats faster, and reduce risks. Centralized management platforms are critical for the efficient administration of distributed networks at scale.
