    9 open recommendations
    Recommendation: The Secretary of Homeland Security should direct Network Security Deployment (NSD) to determine the feasibility of enhancing NCPS's current intrusion detection approach to include functionality that would detect deviations from normal network behavior baselines.

    Agency: Department of Homeland Security
    Status: Open

    Comments: April 2017 Update: In Feb. 2017, DHS officials stated that they have continued pilot activities that will enable DHS to identify suspicious network activity based on anomalous behavior and reputation and have collected lessons learned that are being tracked by the NCPS Program Management Office. Officials added that DHS had identified a contractor to support the transition of the pilot, including drafting an implementation plan; however, it had yet to award a contract due to lack of resources. As such, the agency did not have an estimated date on the completion of a draft plan for how the transition would be implemented. We requested that DHS provide a copy of the draft implementation plan for our review, when it became available. We will continue to monitor DHS's progress in addressing this recommendation.
    Recommendation: The Secretary of Homeland Security should direct NSD to determine the feasibility of developing enhancements to current intrusion detection capabilities to facilitate the scanning of traffic not currently scanned by NCPS.

    Agency: Department of Homeland Security
    Status: Open

    Comments: April 2017 update: In Feb. 2017, DHS officials stated that the NCPS Program Management Office is working with participating Internet Service Providers (ISP) to develop plans to support IPv6 for Traffic Aggregation, DNS redirection, and SMTP quarantining capabilities. Officials stated that an implementation plan that would include all ISP schedules for all planned intrusion prevention services would be available in the third quarter of fiscal year 2017. Additionally, regarding encrypted traffic, officials stated that it is conducting an analysis of Security on Encrypted Traffic (SonET) to better understand options for addressing the challenges, viability of options, and how the issue is being addressed at a broader industry level. The study is scheduled to continue through the fourth quarter of fiscal year 2017. We asked DHS to provide the ISP implementation plans (when finalized) and any findings from the ongoing SCADA and Encrypted traffic studies. We will continue to monitor DHS's progress in addressing this recommendation.
    Recommendation: The Secretary of Homeland Security should direct United States Computer Emergency Readiness Team (US-CERT) to update the tool it uses to manage and deploy intrusion detection signatures to include the ability to more clearly link signatures to publicly available, open-source data repositories.

    Comments: April 2017 update: In Feb. 2017, DHS stated that the NCPS PMO is working with participating Internet Service Providers (ISP) to develop plans to support IPv6 for Traffic Aggregation, DNS redirection, and SMTP quarantining capabilities. Officials stated that an implementation plan that would include all ISP schedules for all planned intrusion prevention services would be available in the third quarter of fiscal year 17. Additionally, officials stated that NSD is conducting an analysis on Security on Encrypted Traffic (SonET) to better understand options for addressing the challenges, viability of options, how the issue is being addressed at a broader industry level. The study will continue through the fourth quarter of fiscal year 2017. We asked DHS to provide the ISP implementation plans (when finalized) and any output/results (findings) from the ongoing studies DHS has related to SCADA and Encrypted traffic. We will continue to monitor DHS's progress in addressing this recommendation.
    Recommendation: The Secretary of Homeland Security should direct US-CERT to consider the viability of using vulnerability information, such as data from the Continuous Diagnostics and Mitigation program as it becomes available, as an input into the development and management of intrusion detection signatures.

    Agency: Department of Homeland Security
    Status: Open

    Comments: April 2017 update: In Feb. 2017, DHS officials stated that enhancements were made so that Continuous Diagnostics and Mitigation program (CDM) data can be viewed with the Cyber Indicators Analysis Program (CIAP). Officials stated that the CDM data now may be combined with known vulnerability findings from NCATS and known threats collected from the CIAP system to further prioritize signature development as necessary. We have requested a meeting with DHS to observe the described enhancements. We believe that we will be able to close this recommendation, once we observe the claimed enhancements.
    Recommendation: The Secretary of Homeland Security should direct US-CERT to develop a timetable for finalizing the incident notification process, to ensure that customer agencies are being sent notifications of potential incidents, which clearly solicit feedback on the usefulness and timeliness of the notification.

    Agency: Department of Homeland Security
    Status: Open

    Comments: April 2017 Update: In Feb. 2017, DHS stated that US-CERT is in the process of developing a targeted survey of EINSTEIN customers (based off of a prior survey). Additionally, US-CERT has updated the Incident Reporting Guidelines to address previously mentioned process concerns. We have requested a copy of these guidelines and will review the modifications made within. Additionally, DHS stated that modifications to the Remedy ticketing system are underway that would allow for the inclusion of user feedback. These changes are anticipated to be implemented by October 2017. We likely would not be able to close this recommendation until we could review the results of the modifications.
    Recommendation: The Secretary of Homeland Security should direct the Office of Cybersecurity and Communications to develop metrics that clearly measure the effectiveness of NCPS's efforts, including the quality, efficiency, and accuracy of supporting actions related to detecting and preventing intrusions, providing analytic services, and sharing cyber-related information.

    Agency: Department of Homeland Security
    Status: Open

    Comments: April 2017 update: In Feb. 2017, DHS officials stated that the Office of Cyber Security and Communications (CS&C) had developed, refined, and were baselining a first set of measures that relate to the Einstein 3A program. Further, they are considering adding one of these measures as an addition to the measures tracked in support of the yearly Government Performance and Results Act (GPRA) required reporting in FY 2018. Additionally, DHS officials stated they are developing information sharing related measures, including exploring how its public and private sector recipients of information measure the value cyber threat indicators and defensive measures. In March 2017, we requested a copy of the developed measures, when they became available. This recommendation will remain open until we are able to review the developed metrics and the subsequent data they are to measure.
    Recommendation: The Secretary of Homeland Security should direct the Office of Cybersecurity and Communications to develop clearly defined requirements for detecting threats on agency internal networks and at cloud service providers to help better ensure effective support of information security activities.

    Comments: April 2017 update: In Feb. 2017, DHS provided memos that gave an overview of the planned enhancements to the Continuous Diagnostics and Mitigation (CDM) program that included references to cloud providers. However, DHS did not provide any specific requirements for us to review. We have requested a follow-up meeting to review the specific requirements developed in support of the planned enhancements described in the provided memos. We will not be able to close this recommendation until we can review the developed requirements and determine that cloud providers are appropriately covered.
    Recommendation: The Secretary of Homeland Security should direct NSD to develop processes and procedures for using vulnerability information, such as data from the Continuous Diagnostics and Mitigation program as it becomes available, to help ensure DHS is using a risk-based approach for the selection/development of future NCPS intrusion prevention capabilities.

    Agency: Department of Homeland Security
    Status: Open

    Comments: April 2017 update: In Feb. 2017, DHS stated that the NCPS Program Management Office has made enhancements to the Continuous Diagnostics and Mitigation (CDM) dashboard, but had yet to fully develop the CDM/NCPS data correlation. In March 2017, we asked for update on the status of data correlation, once available. In order to close this recommendation, we would need to review this model and determine how, if at all, the vulnerability information was used as part of a risk-based approach to intrusion prevention.
    Recommendation: The Secretary of Homeland Security should direct NSD to work with their customer agencies and the Internet service providers to document secure routing requirements in order to better ensure the complete, safe, and effective routing of information to NCPS sensors.

    Status: Open

    Comments: April 2017 update: In Feb. 2017, DHS officials stated that the agency worked with the Office of Management and Budget to develop a draft Trusted Internet Connections Reference Architecture. This architecture is to serve as the new guidance for agencies on perimeter security capabilities as well as alternative routing strategies. In March 2017, we requested a copy of the guidance to review the alternative routing guidance. This recommendation will remain open until we have been able to review the information above.
