A cold site is a backup facility that provides minimal infrastructure and requires significant time to become operational after a disaster. It typically includes only basic physical space, utilities, and possibly some hardware.

Definition of Backup Sites:

Cold Site: Minimal or no IT infrastructure; requires setting up systems, installing software, and restoring data, leading to the longest recovery time.

Hot Site: Fully equipped with operational IT infrastructure; minimal setup time required for recovery.

Warm Site: Partially equipped with essential systems but requires additional setup and restoration before becoming fully operational.

Mobile Backup Site: Portable and flexible backup sites with quicker setup times but still slower than hot sites.

Recovery Time Comparison:

Cold sites are cost-effective but slowest for recovery.

They are suitable for organizations with lower criticality needs or budget constraints.

Use Cases:

Best for non-critical applications or organizations willing to tolerate extended downtime.

Disaster Recovery Planning: EC-Council outlines the use of backup sites as part of a comprehensive disaster recovery plan, emphasizing the trade-offs between cost and recovery time.

Risk Management Framework: The importance of selecting backup sites based on organizational risk tolerance and business continuity needs is stressed.

 Explanation:

Deep-packet inspection (DPI) involves analyzing the content of packets in real-time as they traverse a network.

DPI can examine both headers and payloads of packets without introducing noticeable latency, making it suitable for real-time traffic monitoring.

 Why Other Options Are Incorrect:

A. Traffic analysis: Focuses on metadata such as packet sizes, timing, and flow but does not inspect content.

C. Packet sampling: Involves analyzing only a subset of packets, potentially missing key information.

D. Heuristic analysis: Used for identifying patterns but does not specifically describe real-time deep inspection of packets.

 EC-Council CISO Reference:

DPI is a critical technology discussed in advanced network security for monitoring and identifying malicious activity without impacting performance.

The Simple Network Management Protocol (SNMP) uses "community strings" as a form of authentication. The default read-only string for SNMP is often set to "Public".

SNMP Overview:

SNMP is used for monitoring and managing network devices such as routers, switches, and servers.

Default Community Strings:

Default strings like "Public" (read-only) and "Private" (read-write) are well-known and often targeted by attackers if not changed.

Penetration Test Findings:

Discovering devices through SNMP indicates improper security practices where default settings haven’t been updated, making devices vulnerable.

Mitigation:

Change SNMP community strings to strong, unique values.

Restrict SNMP access to trusted IP ranges.

Configuration Management: Emphasizes updating default settings as a baseline security measure.

Penetration Testing Insights: Findings like this are critical for improving network security posture, aligning with EC-Council’s penetration testing methodologies.

 Investigative Support for Open Guest Networks:

IP and MAC addresses associated with network activity provide crucial identifiers for tracing a user's activity. This is especially helpful for law enforcement when investigating illegal activities.

 Why IP and MAC Address Are Critical:

IP Address: Helps identify network traffic origin during a specific time frame.

MAC Address: Provides device-specific identification.

 Why Not Other Options:

A. Configure logging on each access point: While useful, it does not directly assist without extracting IP and MAC addresses.

B. Install firewall software: Does not help track user activity retroactively.

D. Disable SSID broadcast and enable MAC filtering: Prevents unauthorized access but doesn’t support investigations.

 EC-Council CISO Alignment:

Proper logging and identification practices ensure legal compliance and effective support during investigations.
