ISO/IEC 27035-1:2016 Principles of Incident ManagementThe incident management process is described in five phases: Plan and prepare: establish an information security incident management policy, forman Incident Response Team, etc. Detection and reporting: someone has to spot and report “events” that might be or turninto incidents. Assessment and decision: someone must assess the situation to determine whether itis in fact an incident. Responses: contain, eradicate, recover from and forensically analyze the incident,where appropriate. Lessons learned: make systematic improvements to the organization’s management ofinformation risks as a consequence of incidents experienced.Source: undations of Incident Management (FIM) 2021 Carnegie M ellon University[DISTRIBUTION STATEMENT A] Approved for public releaseand unlimited distribution.12

Regional InitiativesVarious areas have set up regional CSIRT initiatives. TF-CSIRT in Europe APCERT in the Asia Pacific areaThese initiatives involve creating an organizational entity for participation by CSIRTs withina geographic area.These organizational entities are usually voluntary in nature can provide services or support to participating CSIRTs allow teams sharing similar legislative, cultural, and time zone issues to collaborate andcoordinate incident handling activitiesFoundations of Incident Management (FIM) 2021 Carnegie M ellon University[DISTRIBUTION STATEMENT A] Approved for public releaseand unlimited distribution.51

Impact on CSIRTsToday’s dynamic and integrated environment means less time for CSIRTs to react and theneed for more interaction, communication, and data sharing.Therefore, teams require a method for quick notification established and understood policies and procedures automation of incident handling tasks methods to collaborate and share information with others easy and efficient ways to sort through and correlate all incoming information tools to display real-time network and system status assistance in preventing attacks from occurringFoundations of Incident Management (FIM) 2021 Carnegie M ellon University[DISTRIBUTION STATEMENT A] Approved for public releaseand unlimited distribution.54

Needed Tools, Techniques, and SkillsUnderstanding network concepts and fundamentals defense-in-depth strategies intruder exploits and attacks mitigation and containment strategies new tools such as- Data Execution Prevention (DEP)- Address Space Layout Randomization (ASLR)Being able to perform packet capture analysis netflow analysis surface and runtime analysis forensics evidence collection and analysis signature development data analysis, correlation, and visualization incident containment, response, and coordinationFoundations of Incident Management (FIM) 2021 Carnegie M ellon UniversityAlong with understanding risk management concepts and techniques enterprise and mission focus policy impact project management concepts andtechniquesBeing able to perform business and operational impact analysis trend analysis situational awareness data collectionAnd being a team player good communicator and collaborator[DISTRIBUTION STATEMENT A] Approved for public releaseand unlimited distribution.57

CSIRTs Are Customer-service FocusedCSIRTs still need to continue focusing on communicating with stakeholders and collaborators developing trusted relationships coordinating detection, analysis, and response efforts finding ways to share meaningful and actionable information in a secure and timelymanner finding better faster methods of detection and response helping others find better ways for developing secure software and methods ofprevention providing awareness and training obtaining practical experience through coordinated cyber exercisesFoundations of Incident Management (FIM) 2021 Carnegie M ellon University[DISTRIBUTION STATEMENT A] Approved for public releaseand unlimited distribution.58

Management Issues ReviewAs an incident handler you may focus on technical analysis and solutions, but to beeffective you have to understand some organizational and management issues. What are the critical services and data that need to be protected in your organizationor constituency? What is your mission? What role do you play in the organization or constituency? How does your work interface with other parts of your organization or constituency?Foundations of Incident Management (FIM) 2021 Carnegie M ellon University[DISTRIBUTION STATEMENT A] Approved for public releaseand unlimited distribution.59

Novice vs. Mature TeamsOur experiences have shown that generally new teams need time to establish relationships with constituents, stakeholders, and collaborators end up focusing on more reactive versus proactive services have less well defined interfaces and procedur
