An Open Source Approach to Automating Surveillance and Compliance of Automatic Test Systems. 2019 IEEE AUTOTESTCON. :1–8.

2019. With the disconnected nature of some Automatic Test Systems, there is no possibility for a centralized infrastructure of sense and response in Cybersecurity. For scalability, a cost effective onboard approach will be necessary. In smaller companies where connectivity is not a concern, costly commercial solutions will impede the implementation of surveillance and compliance options. In this paper we propose to demonstrate an open source strategy using freely available Security Technical Implementation Guidelines (STIGs), internet resources, and supporting software stacks, such as OpenScap, HubbleStack, and (ElasticSearch, Logstash, and Kibana (ElasticStack)) to deliver an affordable solution to this problem. OpenScap will provide tools for managing system security and standards compliance. HubbleStack will be employed to automate compliance via its components: NOVA (an auditing engine), Nebula (osquery integration), Pulsar (event system) and Quasar (reporting system). Our intention is utilize NOVA in conjunction with OpenScap to CVE (Common Vulnerabilities and Exposures) scan and netstat for open ports and processes. Additionally we will monitor services and status, firewall settings, and use Nebula's integration of Facebook's osquery to detect vulnerabilities by querying the Operating System. Separately we plan to use Pulsar, a fast file integrity manger, to monitor the integrity of critical files such as system, test, and Hardware Abstraction Layer (HAL) software to ensure the system retains its integrity. All of this will be reported by Quasar, HubbleStack's reporting engine. We will provide situational awareness through the use of the open source Elastic Stack. ElasticSearch is a RESTful search and analytics engine. Logstash is an open source data processing pipeline that enables the ingestion of data from multiple sources sending it through extensible interfaces, in this case ElasticSearch. Kibana supports the visualization of data. Essentially Elastic Stack will be the presentation layer, HubbleStack will be the broker of the data to Elastic Stash, with the other HubbleStack components feeding that data. All of the tools involved are open source in nature, reducing the cost to the overhead required to keep configurations up to date, training on use, and analytics required to review the outputs.
