2. Inter-Firewall Analytics
• Inter-firewall analytics involve the examination and monitoring of
network traffic that moves between different segments of a
network, each protected by its own firewall or security perimeter.
• This analysis focuses on understanding the communication
patterns and potential threats that emerge when data crosses
these security boundaries.
• It aims to detect anomalies, unauthorized access, or malicious
activities that might occur during data transfer between different
zones.

3. Inter-Firewall Analytics
• Key aspects of inter-firewall analytics include:
1. Traffic Monitoring: Monitoring and analyzing data flows
between different security zones or segments of a network.
2. Anomaly Detection: Detecting unusual or suspicious traffic
patterns that might indicate unauthorized access or malicious
activity.
3. Access Control Verification: Ensuring that access controls and
security policies are consistently enforced across different zones.
4. Intrusion Detection and Prevention: Identifying and
mitigating potential intrusion attempts or security breaches that
occur when data crosses firewall boundaries.

5. Trans-Firewall Analytics
• Trans-firewall analytics extend the analysis to include data that
moves between different networks or security domains,
potentially involving external entities.
• This type of analysis focuses on understanding the behavior and
risks associated with data flows that traverse not only internal
network boundaries but also external connections.

6. Trans-Firewall Analytics
• Key aspects of trans-firewall analytics include:
1. External Threat Detection: Identifying and mitigating threats that
might arise when data enters or leaves the organization's network,
interacting with external entities.
2. Data Leakage Prevention: Ensuring sensitive or confidential
information is not inadvertently exposed when crossing network
boundaries.
3. Third-Party Risk Management: Assessing the security of
connections and interactions with external partners, vendors, or
service providers.
4. Malware and Threat Detection: Detecting potential malware,
viruses, or other malicious content that might be introduced from
external sources.
