The 7 phases of Incident Response (IR), popularized by the SANS Institute, are Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned, and Testing, forming a structured cycle to manage cybersecurity threats from initial readiness through post-incident improvement, focusing on detecting, responding to, and preventing future attacks.
What are the 7 steps of incident response?
The 7 phases of incident response provide a structured lifecycle for handling cyber threats, typically including Preparation, Detection/Identification, Containment, Eradication, Recovery, Lessons Learned, and Continuous Improvement, guiding organizations from preventing incidents to enhancing future defenses, with slight variations in naming (like NIST's broader categories) across frameworks like SANS.
What are the 7 steps to incident investigation?
The 7 steps of accident investigation typically involve: Securing the Scene, Gathering Information (photos, documents, witness statements), Analyzing Data (identifying immediate causes), conducting a Cause/Root Cause Analysis, developing Corrective Actions, Reporting Findings, and Implementing Changes to prevent recurrence, focusing on system failures, not blame. While steps can vary slightly by source, these core phases cover the essential process from incident response to prevention.
What are the 7 steps of NIST?
The NIST 7 Steps refer to the Risk Management Framework (RMF) for information systems, a structured process to manage security and privacy risks, which includes: Prepare, Categorize, Select, Implement, Assess, Authorize, and Monitor, guiding organizations from initial setup to continuous oversight.
What are P1, P2, P3, and P4 incidents?
P1 – the task affects customers. P2 – the task affects customers, but there is a non-technical workaround. P3 – the task doesn't affect customers. P4 – unused.

What are the 5 C's of incident command?
The "5 C's of Incident Command" can refer to different models, but commonly describe core principles like Command, Control, Coordination, Communication, and Collaboration, emphasizing leadership, structure, teamwork, and information flow; alternatively, it can describe procedural steps like Confirm, Clear, Cordon, Control, and Communicate, focusing on immediate actions for safety and containment in physical incidents. While some systems use the functional areas of ICS (Command, Operations, Logistics, Planning, Finance/Admin) as the "C's", the key is establishing authority, managing resources, ensuring safety, and keeping everyone informed.
What is sla P1, P2, P3, P4?
P1, P2, P3, P4 in an SLA (Service Level Agreement) represent incident priority levels, determined by Urgency (how fast it needs fixing) and Impact (how many users/systems are affected), dictating response/resolution times: P1 (Critical/Outage) demands immediate action (minutes/hours), P2 (High/Major Functionality Loss) needs rapid resolution (hours), P3 (Medium/Limited Impact) is handled in regular cycles (days), and P4 (Low/Minor/Cosmetic) is low priority (weeks/backlog).
What are the 7 principles of risk management?
The 7 key principles of risk management—a proactive approach, systematic process, informed decisions, integrated framework, resource allocation, transparency and communication, and continuous monitoring and review—provide the blueprint for an effective risk management program.
What are the 6 phases of RMF?
The NIST RMF is a structured and repeatable process outlined by the National Institute of Standards and Technology (NIST) to manage information security and privacy risks for organisations and systems. It comprises six key steps: Prepare, Categorise, Select, Implement, Assess, and Authorise.
What are the 5 pillars of NIST?
The NIST Cybersecurity Framework (CSF) is built around five core functions, often called pillars, that guide an organization's cybersecurity risk management: Identify, Protect, Detect, Respond, and Recover, helping businesses understand, manage, and reduce cybersecurity risks for critical infrastructure and operations. In its newer Version 2.0, a sixth foundational function, Govern, was added to emphasize top-level strategy and policy, making it a more robust framework.
What are the 4 phases of IR?
The NIST incident response process is an ongoing activity helping organizations learn how to protect themselves. It includes four main stages: preparation, detection/analysis, containment/eradication, and recovery.
What are the 8 steps of incident investigation?
The document outlines 8 steps for incident investigation: 1) gather information, 2) establish facts, 3) isolate contributing factors, 4) determine causes and root cause, 5) determine corrective actions, 6) review findings, 7) analyze incidents, 8) implement corrective actions.
What are the 5 main components of ICS?
The five core components (or functional areas) of the Incident Command System (ICS) are Command, Operations, Planning, Logistics, and Finance/Administration, which organize all aspects of emergency response under a single, adaptable framework, with a sixth function, Intelligence, added as needed. These sections work together to define goals, manage tactical efforts, provide resources, plan future actions, and track costs during incidents.
What are the 7 steps of accident investigation?
The 7 steps of accident investigation typically involve: Securing the Scene, Gathering Information (photos, documents, witness statements), Analyzing Data (identifying immediate causes), conducting a Cause/Root Cause Analysis, developing Corrective Actions, Reporting Findings, and Implementing Changes to prevent recurrence, focusing on system failures, not blame. While steps can vary slightly by source, these core phases cover the essential process from incident response to prevention.
What are the phases of incident?
The NIST incident response lifecycle breaks incident response down into four main phases: Preparation; Detection and Analysis; Containment, Eradication, and Recovery; and Post-Event Activity.
What are the steps of the overall IR development process?
What are the steps of the overall IR development process? The overall IR process is made up of four phases: preparation; detection and analysis; containment, eradication, and recovery; and post-incident activity.
What are the 7 steps of risk management?
The 7 steps of the risk management process involve systematically establishing context, identifying potential risks, assessing/analyzing their severity and likelihood, deciding on risk treatments/responses, creating and implementing a plan, and finally reviewing and evaluating the effectiveness of the entire process for continuous improvement.
What does RMF stand for?
RMF most commonly stands for Risk Management Framework, a structured process from NIST, used by U.S. federal agencies and others to manage cybersecurity and information system risks through steps like preparing, categorizing, selecting, implementing, assessing, authorizing, and monitoring. It can also refer to other things, such as the Royal Munster Fusiliers, a historical military regiment, or interpretations like Reckless Manipulated Fool in the context of the film Kinds of Kindness.
What are the NIST phases?
The four components of the NIST incident response cycle in order are: preparation, detection and analysis, containment, eradication, and recovery, and post-incident activity. Each phase has a goal and role in incident response.

What is the 7th principle of management?
Principle 7: Relationship Management
The seventh principle of quality management is relationship management. As we know, relationships are a very important variable for any business.
What is a KPI and SLA?
An SLA (Service Level Agreement) is a formal, contractual promise between a provider and customer defining service quality (like uptime, response time), while a KPI (Key Performance Indicator) is a measurable value showing how well the provider is meeting business objectives, often tracking the SLA's targets and overall strategic goals, with penalties for missing SLAs but KPIs guiding broader success. Essentially, KPIs are the metrics (e.g., 99.9% uptime), and the SLA is the agreement that guarantees meeting those specific KPI targets, often with financial consequences if failed.
