ResponsibilitiesConducting ResearchUses research findings to develop guidance on security issues to inform improvements and resolution. Shares within team. Interacts with industry and research partners on ad hoc or as needed basis.Prioritizes and validates technical indicators. Aggregates threat data into categories and themes that align to intelligence requirements or customer requests. Takes into consideration relative risk factors, history of published vulnerabilities and existing security knowledge into their analysis. Develops tools to assist in automating the analysis of a component or feature area.Performs analysis using multiple data sources to generate insights. Considers common and potential threat scenarios and dependencies in analyses. Attends to and understands connections between identified issues and up- and-down stream processes. Helps to drive resolution to systemic security issues. Aids in the creation of new solutions to mitigate security issues. Makes tradeoffs to balance security and operational needs.Identifies and conducts research into critical security areas, such as competitor products, current attacks, adversary tracking, and academic literature. Aids in the design of solutions to prevent attacks. Designs lead to engineering projects. Investigates the root cause, motivation, and impact of security issues. Incorporates feedback and results from research into future research.Cleans, structures, and standardizes data and data sources. Supports data quality efforts to ensure timely and consistent access to data sources. Curates sources of data and partners to develop and sustain data access. Understands how to find new data sources.Industry LeadershipDemonstrates deep expertise in a defined set of security issues, tools, mitigations, and processes (e.g., architecture, failure modes, attack chain, threat modeling, vulnerabilities).Provides guidance to others in areas of expertise. Maintains current knowledge by investing time and effort. Proactively seeks opportunities to learn. Demonstrates appropriate risk taking and ethical behavior.Learns and understands the current state of the industry, including knowledge of tools, techniques, strategies, and processes that can be utilized to improve security. Maintains knowledge of current trends within the industry.OrchestrationSupports the management of incidents by applying technical knowledge to diagnose and triage issues with a commitment to maintaining the quality of products and services. Takes notes during incidents and participates in postmortem and root-cause analysis processes.Protects tools, techniques, information, and results of security practices. Assesses efficacy of operational security (e.g., red-on-red pen testing). Begins to master techniques.Identifies areas of dependency and overlap with other teams or team members. Provides constructive input so the work is integrated and timely. Communicates status with others to allow for timely resolution and coordination. Helps teams identify risks, dependencies and other blocking issues. Enables others to take action to resolve issues.Creates analysis report. Follows up on the findings and recommendations, escalating blocking issues as needed. Identifies potential security vulnerabilities by reviewing documentation and specifications. Develops facts and libraries of guidance.Solution GenerationDrives end-to-end solution for technical implementation and automation related to specific kinds or classes of security issues (e.g., signature detection, malware, threat analysis, reverse engineering). Develops higher level awareness of other kinds of security issues outside areas of expertise. Works across disciplines to solve specific issues. Uses results from research and experimentation to guide architecture or product direction.Identifies and responds to customer and partner security issues in a timely manner. Spots trends and potential security issues. Advocates for customers and partners. Provides assistance to customers and partners. Leverages partner and customer feedback to improve assistance. Escalates issues as needed. Develops guidance and education that result from resolution of security issues.Identifies and addresses underlying causes of security shortcomings. Develops security guidance and models to address shortcomings and to build best practices. Suggests and drives appropriate guidance, models, response, and remediation for issues.Other ResponsbilitiesInvestigate, analyze, and learn from security researchers, attackers, and real incidents to develop durable protection solution/strategies. Identify and conduct research into critical security areas, such as current attacks, adversary tracking, and academic literature. Aid in the design of solutions to prevent attacks. Work with other internal and external teams to forge new and improve existing partnerships that help mature the product. Provide exemplary leadership in an exceptionally challenging and rewarding environment and influence the organization. Collaborate with other researchers, coordinators, and developers to improve the protection capabilities of the products. | |
