Impact analysis
Utilize AI-driven analytics to assess the potential impact of security incidents, offering insights into affected systems and data to prioritize response efforts effectively.
Reverse engineering of scripts
Eliminate the need to manually reverse engineer malware and enable every analyst to understand the actions executed by attackers. Analyze complex command line scripts and translate them into natural language with clear explanations of actions. Efficiently extract and link indicators found in the script to their respective entities in your environment.
Guided response
Receive actionable step-by-step guidance for incident response, including directions for triage, investigation, containment, and remediation. Relevant deep links to recommended actions allow for quicker response.
How does Copilot for Security work?
Microsoft Copilot for Security capabilities can be accessed through an immersive standalone experience and through intuitive embedded experiences available in other Microsoft security products. The foundation language model and proprietary Microsoft technologies work together in an underlying system that helps increase the efficiency and capabilities of defenders.
Microsoft security solutions such as Microsoft Defender XDR, Microsoft Sentinel, Microsoft Intune integrate seamlessly with Copilot for Security. There are some embedded experiences available in Microsoft security solutions that give access to Copilot for Security and prompting capabilities in the context of their work within those solutions.
Plugins from Microsoft and third-party security products are a means to extend and integrate services with Copilot for Security. Plugins bring more context from event logs, alerts, incidents, and policies from both Microsoft security products and supported third-party solutions such as ServiceNow.
Copilot for Security also has access to threat intelligence and authoritative content through plugins. These plugins can search across Microsoft Defender Threat Intelligence articles and intel profiles, Microsoft Defender XDR threat analytics reports, and vulnerability disclosure publications, among others.
Here's an explanation of how Microsoft Copilot for Security works:
User prompts from security products are sent to Copilot for Security.
Copilot for Security then preprocesses the input prompt through an approach called grounding, which improves the specificity of the prompt to help you get answers that are relevant and actionable to your prompt. Copilot for Security accesses plugins for preprocessing, then sends the modified prompt to the language model.
Copilot for Security takes the response from the language model and post-processes it. This post-processing includes accessing plugins to gain contextualized information.
Copilot for Security returns the response, where the user can review and assess the response.
Copilot for Security iteratively processes and orchestrates these sophisticated services to help produce results that are relevant to your organization because they're contextually based on your organizational data.
