Summary:
This document outlines a detailed examination of several components within a retail environment, specifically focusing on ArcNet Retail Stores. Key points include:
1. **Compliance Dashboard**: Two requirements (req #1 and req #10) are open in the Compliance Dashboard. 2. **Assets**: The navigator is highlighting assets related to ArcNet Retail, particularly brick-and-mortar store locations mapped for each store. 3. **Billing Systems**: - **DMZ (Demilitarized Zone)**: Stores communicate with the billing department to process credit card transactions. - **Backend**: Stores use this system to store actual credit card data. - **Web Presence and Billing System**: The retail environment includes an ecommerce presence managed by a third-party billing system, which must be monitored for PCI (Payment Card Industry) compliance. 4. **Security and Network Monitoring**: Various security measures and network performance indicators are reviewed, including SSL/Heartbeat/Bandwidth Utilization, with continuous monitoring of online communication with third-party billing systems. 5. **Geographical Representation**: Focusing on the West coast, all Bay area stores are brought into view, revealing issues such as non-compliant stores (Store 2 and Store 22) in terms of POS systems not being PCI compliant. 6. **Infrastructure Issues**: Identified problems include terminated user accounts, insecure services like FTP traffic on a Checkpoint Firewall, and telnet service activation on store devices. 7. **Logon Attempts and User Sessions**: Logins by users "JimmyJ" and "Scott" were successful but triggered further investigation due to potential security issues. 8. **PCI Compliance**: An incident response involved reviewing PCI security standards, particularly focusing on contractor access to the building where restricted badge access was detected. 9. **Incident Response**: A case was created for suspicious activities involving file deletions, data exposure, and manipulation of audit logs. 10. **Recommendations**: Suggestions include customizing views, conducting investigations using drill-down tools, showing requirement 1 on the Compliance dashboard, and reviewing PCI reports for further investigation.
The document emphasizes compliance and secure configurations across all aspects of the retail environment, particularly in handling sensitive customer data through billing systems and POS devices.
Details:
The provided text describes a detailed examination of several components within a retail environment, particularly focusing on ArcNet Retail Stores. Here's a summarized breakdown of the key points mentioned:
1. **Compliance Dashboard**: Two specific requirements (req #1 and req #10) are open in the Compliance Dashboard.
2. **Assets**: The navigator is highlighting assets related to ArcNet Retail, specifically brick-and-mortar store locations mapped for each store.
3. **Billing Systems**:
**DMZ (Demilitarized Zone)**: This is where stores communicate with the billing department to process credit card transactions.
**Backend**: Stores use this system to store actual credit card data.
**Web Presence and Billing System**: The retail environment includes an ecommerce presence managed by a third-party billing system, which must be monitored for PCI (Payment Card Industry) compliance.
4. **Security and Network Monitoring**:
**SSL/Heartbeat/Bandwidth Utilization**: Various security measures and network performance indicators are reviewed.
**SOC/NOC (Security Operations Center/Network Operations Center)**: The system continuously monitors online communication with third-party billing systems, including direct communications to the DMZ and stores.
5. **Geographical Representation**:
Drilling down from North America (NA) stores shows a distribution across the region.
Focusing on the West coast, all Bay area stores are brought into view.
Store 2 and Store 22 are identified as non-compliant; detailed analysis of these stores reveals issues such as POS systems not being compliant with PCI standards and local transaction databases.
6. **Infrastructure Issues**:
**Terminated User Accounts**: Logs indicate a failed login attempt by "JimmyJ" (likely due to using an insecure method) on the terminated user active list, which triggered access attempts.
**Insecure Services**:
Checkpoint Firewall allowing FTP traffic to port 21 (clear text protocol), potentially exposing sensitive data.
Windows event detecting telnet service activation, indicating insecure configurations or services running on store devices.
7. **Logon Attempts and User Sessions**:
"JimmyJ" successfully logs in as "fairlane," triggering updates to current user sessions using session correlation due to OS login events.
Another successful logon occurred with the default user "Scott," also indicating a need for standard security practices within the system.
The text concludes by emphasizing the importance of compliance and secure configurations across all aspects of the retail environment, particularly in handling sensitive customer data through billing systems and POS devices.
This document outlines a series of security measures and actions taken in response to an attack involving the user "fairlane." The user fairlane attempted to log on using the shared account "Shared_dba" and accessed CC_Numbers, sending them via email. This action was detected by Snort as an authentication attempt related to credit card information (CC). Two correlations were triggered: insecure services and the exposure of CC numbers in clear text.
Further investigation revealed several suspicious activities including file deletions on transaction records, customer data, and salaries. Additionally, the audit log was cleared and the oracle table "audit$" was manipulated, which also violated auditing rules. A case was created for this incident, and an event graph was generated using fairlane's user name and target zone to map related events. The case can be followed up on a Compliance dashboard to check compliance status.
The investigation also involved reviewing PCI (Payment Card Industry) security standards, specifically focusing on contractor access to the building where restrictions were highlighted by the identity correlation of Bryant. A restricted badge access alert was correlated and mapped using identity correlation as well.
In conclusion, this document details a comprehensive approach to incident response, including technical measures such as monitoring login activities and suspicious deletions, along with procedural steps like creating cases and following up on compliance checks.
The text is discussing an issue with PCI events channel, where there was unusual behavior observed. To address this, the user suggests customizing views, conducting investigations, and using drill-down tools for better understanding. They also mention that it would be wise to show requirement 1 on the Compliance dashboard for clarity. Additionally, they recommend reviewing reports related to PCI, such as archives or arcSight solutions, to further investigate the issue.
