Writing a Runbook That Holds Up at 3 a.m.

A runbook that requires reading three Confluence pages at 3 a.m. is not a runbook. The structure has to survive sleep deprivation, partial information, and the specific anxiety of not knowing whether the situation matches the playbook.

A Ninety Day AI Security Roadmap for Security Teams Starting from Zero

The hardest part of AI security is not the technology. It is knowing where to start. This ninety day roadmap gives security teams a prioritized sequence of actions that builds a defensible AI security baseline without requiring a large dedicated team or a mature AI security program.

Security Risks of AI Browser Agents in Enterprise Environments

A browser agent that can fill forms, click buttons, and authenticate to services on behalf of a user is an extremely capable tool and an extremely capable attack surface. The enterprise threat model for browser agents is different from any previous web security problem.

Deepfake Defense for Enterprise Security Teams

Deepfake technology has crossed the capability threshold where it is a practical tool for enterprise fraud, impersonation, and social engineering. Detection alone is insufficient. The response framework must assume detection will sometimes fail.

Privacy Engineering for Enterprise AI Systems

Enterprise AI systems are privacy risk multipliers. A single model trained on inadequately governed data, or a logging pipeline that retains inference inputs, can create regulatory exposure that dwarfs the value of the AI capability itself.

Model Extraction via APIs and the Controls that Raise the Cost

Model extraction turns your API into an unintended model distillation service. The goal of your defenses is not perfect prevention but raising the cost of extraction above the cost of training a substitute from scratch.

Training Data Poisoning Defenses for Production ML Pipelines

Unlike prompt injection, training data poisoning corrupts the model itself rather than a single conversation. The blast radius is every user, every session, indefinitely. Defenses must run upstream of the training job.

Protecting Proprietary Models from Theft and Unauthorized Extraction

A finetuned model represents months of compute, curated data, and engineering effort. Adversaries who cannot afford that investment will try to steal it through APIs, insider access, or supply chain compromise. This article maps the threat and the defenses that hold in practice.

Human Approval Gates for Autonomous Agent Actions

The question of when to require a human to approve an agent action is fundamentally a risk acceptance question. The security team's job is to define what constitutes an irreversible or high impact action, and to ensure that no such action proceeds without explicit approval from an authorized person.

Token and Cost Abuse Defense for LLM Platforms

Token abuse does not trigger malware alerts or authentication failures. It shows up in a cloud bill. By the time finance escalates, the damage is already done. The defense requires treating token consumption as a security metric, not just a cost metric.

Enterprise AI Gateways as a Security Control Layer

An AI gateway does for model API calls what a WAF does for HTTP traffic. It is a centralized enforcement point where policy, authentication, logging, and routing decisions are made once and applied consistently across all AI features in an organization.

MCP Server Security Controls for Enterprise AI Deployments

MCP servers are where AI agents meet real tools. A misconfigured MCP server gives an AI agent the ability to act beyond its intended scope, often without any visibility to the security team. The controls that matter are authentication, tool scope enforcement, and audit logging at the MCP layer.

Managing Third Party Model Risk in Enterprise AI Programs

Third party model risk is not a new category of risk. It is vendor risk applied to an AI specific surface. The challenge is that traditional vendor assessments do not ask the right questions for a system where the vendor controls the transformation layer between your data and your users.

Feeding AI Telemetry into Your SIEM Without Drowning Your Analysts

Sending every LLM interaction to a SIEM without a detection strategy will fill the analyst queue with noise and make real AI threats harder to find. The solution is a tiered telemetry model with purpose built detection rules for AI specific threat patterns.

LLM Audit Logging Standards for Enterprise Security Programs

Most teams log LLM responses. Almost none log what is equally important. The full input context, the tool calls made during the session, the tenant identity that drove the request, and the model version that produced the output. Those four fields are what make root cause analysis possible.

AI Incident Response Playbooks for Security Operations Teams

An AI incident does not look like a classic breach alert. It may look like an unusual spending spike, a tool call that went to the wrong tenant, or an agent that completed tasks nobody authorized. Security operations teams need playbooks designed for these patterns.

AI Security Launch Gates for Production Deployments

Shipping AI features without a launch gate is like merging code without a security review. The fix is not a longer checklist. It is a structured gate with pass or fail criteria that every AI feature must clear before it touches production traffic.

AI Red Team Planning for Enterprise AI Systems

AI red teaming is not traditional penetration testing applied to a new target. Model behavior under adversarial conditions is probabilistic, context dependent, and not reproducible through standard scanning. A well run AI red team exercise requires a structured methodology, a diverse operator team, and a reporting format that translates findings into architectural changes.

Multimodal Input Security for Vision, Audio, and Document AI Systems

Multimodal input surfaces extend the prompt injection problem to content that humans cannot easily review. Instructions embedded in image regions, steganographic audio payloads, and PDF metadata fields are all potential injection vectors for multimodal AI systems. Defense requires preprocessing controls and the same structural isolation applied to text based systems.

Secure Model Output Handling for Web and API Applications

Model output is not safe to render, execute, or pass to downstream systems without validation. LLM generated content that is rendered in a browser without sanitization enables XSS. Output used to construct SQL queries enables injection. Output parsed as commands by downstream agents enables privilege escalation. Treating model output as untrusted is a prerequisite for secure AI integration.

Secret Handling in AI Systems Where Credentials Flow Through Prompts

AI systems create new secret exposure pathways that traditional secret scanners do not cover. A credential in a system prompt can be exfiltrated through a prompt injection. A secret in an indexed document can be retrieved by any user with query access. These pathways require specific architectural patterns to close.

Vector Database Security Controls for Production AI Systems

Vector databases holding embedded PII or proprietary content deserve the same security controls as a relational database holding the same data. Authentication, network isolation, access auditing, and embedding inversion protection are the four pillars of vector database security.

RAG Multi Tenant Isolation Patterns That Hold Under Adversarial Conditions

Multi tenant RAG systems fail silently. There is no error when a retrieved chunk belongs to the wrong tenant. The isolation must be enforced at query time through mandatory tenant filters, not through post retrieval output scanning. This article covers the architecture and the testing approach.

Lin Chen

AI & Adversarial ML8 MIN

Agent Tool Permissions and Least Privilege in Agentic AI Systems

Agent tool permissions are the new privileged access problem. They accumulate through feature additions, are rarely reviewed, and when exploited through prompt injection, give attackers the same capabilities the agent has. Applying least privilege to tool grants requires the same discipline as privileged access management.

Lin Chen

AI & Adversarial ML11 MIN

Prompt Injection Architecture Defense at the System Level

Input filters lose to novel injection variants. The defenses that hold are structural. Separating untrusted text processing from tool enabled reasoning, enforcing schema boundaries between those layers, and gating irreversible actions outside the model are the three patterns that reduce prompt injection from a critical risk to a contained one.

AI Threat Modeling for Production Systems

STRIDE still works for AI systems if you extend it with three AI specific threat categories. The real challenge is drawing the data flow diagram correctly when the model itself is a processing node that can be manipulated through its inputs.
