A generative model produces text. An agentic system&nbsp;<em>does things<\/em>&nbsp;it reads email, books travel, pushes code to production, and triggers downstream automations at machine speed.&nbsp;<\/p>\n\n\n\n<p><strong>Section&nbsp;2<\/strong>&nbsp;<br><strong>What Is Agentic AI? Examples &amp; How It Works<\/strong>&nbsp;<\/p>\n\n\n\n<p>An&nbsp;<strong>AI agent<\/strong>&nbsp;is an autonomous or semi-autonomous software system that uses one or more LLMs as its reasoning engine and combines that with tools, memory, and a feedback loop to achieve goals across multi-step workflows.&nbsp;<\/p>\n\n\n\n<p><strong>Core components<\/strong>&nbsp;<br>Every agentic system is built around four pillars: (1) a&nbsp;<strong>Planner<\/strong>&nbsp;the LLM that receives a goal and decomposes it into steps; (2)&nbsp;<strong>Tools<\/strong>&nbsp;APIs, code executors, browsers, and databases the agent can invoke; (3)&nbsp;<strong>Memory<\/strong> short-term session context and long-term vector stores that persist knowledge across sessions; (4) a&nbsp;<strong>Feedback loop<\/strong> observation of action results, plan updates, and iteration toward the goal.&nbsp;<\/p>\n\n\n\n<p>i.e.&nbsp;Microsoft 365 Copilot \/ Studio, GitHub Copilot Workspace, Salesforce&nbsp;Agentforce&nbsp;<\/p>\n\n\n\n<p><strong>How the loop executes<\/strong>&nbsp;<\/p>\n\n\n\n<p>Given a goal, the agent enters a&nbsp;<em>plan \u2192 act \u2192&nbsp;observe&nbsp;\u2192 replan<\/em>&nbsp;loop. It breaks the goal into tasks, selects a tool for each, formulates and makes the call, receives results, updates its internal context, and moves to the next task. In multi-agent architectures the orchestrator&nbsp;spawns&nbsp;specialist sub-agents, introducing inter-agent communication channels that expand the attack surface dramatically.&nbsp;<\/p>\n\n\n\n<p><strong>Section&nbsp;3<\/strong>&nbsp;<br><strong>The Application-to-Risk Bridge<\/strong>&nbsp;<\/p>\n\n\n\n<p>Traditional application security was designed around a clear boundary: untrusted input flows in, validated output flows out. The application is passive it responds; it does not&nbsp;initiate. Agentic AI obliterates this model in three fundamental ways.&nbsp;<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong><em>The blast-radius problem.<\/em><\/strong><em>&nbsp;A compromised AI agent is not a data breach it is a rogue insider with programmatic speed and access to every tool the organisation gave it. An exploited agent can exfiltrate data, manipulate financial records, inject malicious code into repositories, or cascade failures across connected systems all at machine speed, often without a human reviewer in the loop.<\/em>&nbsp;<\/p>\n<\/blockquote>\n\n\n\n<p>First, agents are&nbsp;<strong>proactive actors<\/strong> they&nbsp;initiate&nbsp;API calls, send emails, write to databases, and trigger automations without waiting to be called. This inverts the threat model entirely. Second, the&nbsp;<strong>instruction surface is unbounded<\/strong> an agent processes not just user prompts but tool outputs, file contents, emails, web pages, and RAG retrievals, any of which can carry&nbsp;adversarial&nbsp;crafted instructions. Third, in multi-agent architectures, agents&nbsp;<strong>inherit and delegate trust<\/strong>&nbsp;a single compromised node can poison the entire workflow.&nbsp;<\/p>\n\n\n\n<p><strong>Section&nbsp;4<\/strong>&nbsp;<br><strong>Agentic AI Security Stack<\/strong>&nbsp;<\/p>\n\n\n\n<p>Securing agentic systems requires a layered, lifecycle-aligned defence model. The stack below is organised into five phases that mirror how an agent\u00a0operates from identity provisioning before the first action, through input screening, tool governance, and runtime monitoring, to post-execution observability and governance.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"821\" src=\"https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack-1024x821.jpg\" alt=\"\" class=\"wp-image-316\" srcset=\"https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack-1024x821.jpg 1024w, https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack-300x241.jpg 300w, https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack-768x616.jpg 768w, https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack-600x481.jpg 600w, https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack-945x758.jpg 945w, https:\/\/musikaar.com\/blog\/wp-content\/uploads\/2026\/04\/Agentic_AI_Security_Stack.jpg 1152w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><br><strong>Phase -1: Identity &amp; Access Governance&nbsp;<em>(before the agent acts)<\/em><\/strong>&nbsp;<br>Every agent must be registered as a Non-Human Identity (NHI) before it is granted access to any resource. Just-in-time, short-lived credentials scoped to the specific task&nbsp;eliminate&nbsp;standing privilege and dramatically reduce the blast radius of any compromise. Without this foundation, all other controls are built on sand.&nbsp;<\/p>\n\n\n\n<p><strong>Phase-2: Input Protection &amp; Goal Security&nbsp;<\/strong><strong><em>(before the agent executes)<\/em><\/strong>&nbsp;<br>Every input to an agent including tool outputs, web pages, email content, and RAG retrievals must be treated as untrusted and screened for adversarial instruction payloads. Indirect prompt injection is the most prevalent real-world exploit class today. PII scrubbing before execution prevents sensitive data exfiltration through agent-generated outputs.&nbsp;<\/p>\n\n\n\n<p><strong>Phase-3:&nbsp;Tool &amp; Supply Chain Security&nbsp;<\/strong><strong><em>(what the agent can touch)<\/em><\/strong>&nbsp;<br>Agentic supply chains are dynamic agents discover and load tools at runtime. Explicitly allowlisting MCP servers with signed manifests,&nbsp;maintaining&nbsp;an AI Bill of Materials (AIBOM), and enforcing argument validation before every tool call are non-negotiable. Real-world incident: a malicious Postmark MCP server&nbsp;BCC&#8217;d&nbsp;every agent-sent email to an attacker with no visible&nbsp;indication&nbsp;in the email thread.&nbsp;<\/p>\n\n\n\n<p><strong>Phase-4:&nbsp;Runtime,&nbsp;Behaviour&nbsp;&amp; Monitoring&nbsp;<\/strong><strong><em>(while the agent runs)<\/em><\/strong>&nbsp;<br>Code generated by an agent must execute only in network-isolated sandboxes. Behavioural baselines define what &#8220;normal&#8221; looks like per agent role deviations trigger alerts or automatic&nbsp;suspension. Inter-agent communication must be authenticated and integrity-verified to prevent message spoofing and cascading failure propagation across the agent graph.&nbsp;<\/p>\n\n\n\n<p><strong>Phase-5:&nbsp;Observability, Red Teaming &amp; Governance&nbsp;<\/strong><strong><em>(after the agent acts)<\/em><\/strong>&nbsp;<br>Every agent action, tool call, and inter-agent message must be logged with enough fidelity to support forensic replay. AI red teaming exercises including adversarial prompt injection and multi-agent chain attacks must be run regularly. Governance frameworks (NIST AI RMF, EU AI Act, ISO 42001) provide the compliance scaffolding that ties the full stack together at the organisational level.&nbsp;<\/p>\n\n\n\n<p><strong>Section&nbsp;5<\/strong>&nbsp;<br><strong>Top Agentic AI Security Threats<\/strong>&nbsp;<\/p>\n\n\n\n<p>Traditional LLM risks focus on prompts, data exposure, and output handling. Agentic AI introduces risks in planning, execution, identity, memory, and communication &#8211; meaning the attack surface is no longer the response, it is the entire workflow.&nbsp;<\/p>\n\n\n\n<p><strong>Where threats occur in the agent execution loop<\/strong>&nbsp;<\/p>\n\n\n\n<p>Agentic AI security works by understanding how autonomous agents&nbsp;operate&nbsp;and then securing the parts of the system that drive their behaviour.
