Fortinet has released out-of-band patches for a critical security flaw impacting FortiClient EMS that it said has been exploited in the wild.
The vulnerability, tracked as CVE-2026-35616 (CVSS score: 9.1), has been described as a pre-authentication API access bypass leading to privilege escalation.
“An improper access control vulnerability [CWE-284] in FortiClient EMS may allow an

The security industry has spent the last year talking about models, copilots, and agents, but a quieter shift is happening one layer below all of that: Vendors are lining up around a shared way to describe security data. The Open Cybersecurity Schema Framework (OCSF), is emerging as one of the strongest candidates for that job.

It gives vendors, enterprises, and practitioners a common way to represent security events, findings, objects, and context. That means less time rewriting field names and custom parsers and more time correlating detections, running analytics, and building workflows that can work across products. In a market where every security team is stitching together endpoint, identity, cloud, SaaS, and AI telemetry, a common infrastructure long felt like a pipe dream, and OCSF now puts it within reach.

OCSF in plain language

OCSF is an open-source framework for cybersecurity schemas. It’s vendor neutral by design and deliberately agnostic to storage format, data collection, and ETL choices. In practical terms, it gives application teams and data engineers a shared structure for events so analysts can work with a more consistent language for threat detection and investigation.

That sounds dry until you look at the daily work inside a security operations center (SOC). Security teams have to spend a lot of effort normalizing data from different tools so that they can correlate events. For example, detecting an employee logging in from San Francisco at 10 a.m. on their laptop, then accessing a cloud resource from New York at 10:02 a.m. could reveal a leaked credential.

Setting up a system that can correlate those events, however, is no easy task: Different tools describe the same idea with different fields, nesting structures, and assumptions. OCSF was built to lower this tax. It helps vendors map their own schemas into a common model and helps customers move data through lakes, pipelines, security incident and event management (SIEM) tools without requiring time consuming translation at every hop.

The last two years have been unusually fast

Most of OCSF’s visible acceleration has happened in the last two years. The project was announced in August 2022 by Amazon AWS and Splunk, building on worked contributed by Symantec, Broadcom, and other well known infrastructure giants Cloudflare, CrowdStrike, IBM, Okta, Palo Alto Networks, Rapid7, Salesforce, Securonix, Sumo Logic, Tanium, Trend Micro, and Zscaler.

The OCSF community has kept up a steady cadence of releases over the last two years

The community has grown quickly. AWS said in August 2024 that OCSF had expanded from a 17-company initiative into a community with more than 200 participating organizations and 800 contributors, which expanded to 900 wen OCSF joined the Linux Foundation in November 2024. 

OCSF is showing up across the industry

In the observability and security space, OCSF is everywhere. AWS Security Lake converts natively supported AWS logs and events into OCSF and stores them in Parquet. AWS AppFabric can output OCSF — normalized audit data. AWS Security Hub findings use OCSF, and AWS publishes an extension for cloud-specific resource details. 

Splunk can translate incoming data into OCSF with edge processor and ingest processor. Cribl supports seamless converting streaming data into OCSF and compatible formats.

Palo Alto Networks can forward Strata sogging Service data into Amazon Security Lake in OCSF. CrowdStrike positions itself on both sides of the OCSF pipe, with Falcon data translated into OCSF for Security Lake and Falcon Next-Gen SIEM positioned to ingest and parse OCSF-formatted data. OCSF is one of those rare standards that has crossed the chasm from an abstract standard into standard operational plumbing across the industry.

AI is giving the OCSF story fresh urgency

When enterprises deploy AI infrastructure, large language models (LLMs) sit at the core, surrounded by complex distributed systems such as model gateways, agent runtimes, vector stores, tool calls, retrieval systems, and policy engines. These components generate new forms of telemetry, much of which spans product boundaries. Security teams across the SOC are increasingly focused on capturing and analyzing this data. The central question often becomes what an agentic AI system actually did, rather than only the text it produced, and whether its actions led to any security breaches.

That puts more pressure on the underlying data model. An AI assistant that calls the wrong tool, retrieves the wrong data, or chains together a risky sequence of actions creates a security event that needs to be understood across systems. A shared security schema becomes more valuable in that world, especially when AI is also being used on the analytics side to correlate more data, faster.

For OCSF, 2025 was all about AI

Imagine a company uses an AI assistant to help employees look up internal documents and trigger tools like ticketing systems or code repositories. One day, the assistant starts pulling the wrong files, calling tools it should not use, and exposing sensitive information in its responses.

Updates in OCSF versions 1.5.0, 1.6.0, and 1.7.0 help security teams piece together what happened by flagging unusual behavior, showing who had access to the connected systems, and tracing the assistant’s tool calls step by step. Instead of only seeing the final answer the AI gave, the team can investigate the full chain of actions that led to the problem.

What’s on the horizon

Imagine a company uses an AI customer support bot, and one day the bot begins giving long, detailed answers that include internal troubleshooting guidance meant only for staff. With the kinds of changes being developed for OCSF 1.8.0, the security team could see which model handled the exchange, which provider supplied it, what role each message played, and how the token counts changed across the conversation.

A sudden spike in prompt or completion tokens could signal that the bot was fed an unusually large hidden prompt, pulled in too much background data from a vector database, or generated an overly long response that increased the chance of sensitive information leaking. That gives investigators a practical clue about where the interaction went off course, instead of leaving them with only the final answer.

Why this matters to the broader market

The bigger story is that OCSF has moved quickly from being a community effort to becoming a real standard that security products use every day. Over the past two years, it has gained stronger governance, frequent releases, and practical support across data lakes, ingest pipelines, SIEM workflows, and partner ecosystems.

In a world where AI expands the security landscape through scams, abuse, and new attack paths, security teams rely on OCSF to connect data from many systems without losing context along the way to keep your data safe.
