At a restaurant the place the waiters, cooks and cooks communicate the identical language however use totally different phrases for what’s on the menu, you would possibly order lobster bisque and wind up with steak frites. The same Tower of Babel challenge exists in cybersecurity, particularly given growing threats in 2023 — totally different safety distributors don’t typically use the identical JavaScript strings to outline occasions and even such parameters as dates and endpoints.

A consortium led by Splunk and AWS are hoping to repair this by standardizing how occasions are famous in logs, lowering the burden on safety groups to decipher alerts they obtain from a number of instruments and distributors.

Open Cybersecurity Schema Framework is mostly out there

Final week at Black Hat, a steering committee comprising Splunk, AWS and IBM introduced the final availability of the Open Cybersecurity Schema Framework. It’s an open-sourced venture hosted on GitHub that’s designed to take away safety knowledge silos and standardize occasion codecs throughout distributors and purposes.

When OCSF was first introduced at Black Hat 2022, 18 organizations had been on board. Now, OCSF includes 145 safety firms together with AWS and IBM and 435 particular person contributors. Splunk describes OCSF as an open and extensible framework that organizations can combine into any surroundings, software or resolution to enrich present safety requirements and processes.

A rose by some other title, besides in JSON

At its coronary heart, OCSF is a JavaScript object notation schema. In JavaScript, knowledge is represented with a collection of code strings with quotes and brackets. Whereas there may be an open normal notation for JavaScript logs referred to as JSON, JSON names for various occasions will not be standardized — that is the problem OCSF is supposed to deal with.

Mark Ryland, director, Workplace of the CISO at AWS, mentioned, “An incredible instance is Greenwich imply time, GMT. Each instrument would possibly encode it, however not in the identical method, so if I’m making an attempt to do a date comparability, I could also be seeing many representations of a given GMT date. Each instrument is describing the fact it sees with a barely totally different variation based mostly on how it’s sharing that data.”

He mentioned that, due to this, analysts find yourself taking a look at a number of screens and in impact chopping and pasting to current knowledge in a denormalized method.

“Working with Splunk and different distributors, we realized if we may lower the period of time spent on knowledge cleaning, munging and transformation, we may enhance productiveness of safety groups, as a result of the issue can be solved in widespread codecs throughout all telemetry,” he mentioned.

Patrick Coughlin, VP, Technical GTM at Splunk, famous that safety groups at organizations typically use as much as 100 instruments, every with totally different constructions, codecs and methods of displaying alerts.

“It’s an enormous drawback after we speak about alert fatigue,” he mentioned. “If I’ve to speak to totally different techniques that speak about alerts in numerous methods, it’s that a lot worse. OCSF brings all of it collectively in a method that makes it far simpler to know, but in addition to automate.”

Ryan Kovar, distinguished safety strategist at Splunk and director of the agency’s SURGe risk intelligence and evaluation unit, mentioned that if, for instance, a ransomware attacker encrypts a file system, the best way this ransomware encryption occasion is acknowledged in an occasion log by one vendor could also be very totally different from how it’s acknowledged by one other.

“If there are a number of proprietary taxonomies for alerts — one for every of your safety distributors — you may now not inform if they’re alerting for a similar occasion or not. In contrast, the safety options that make the most of the OCSF schema produce knowledge in the identical constant format, so safety groups can save effort and time on normalizing the information and get to analyzing it sooner, accelerating time-to-detection.”

How OCSF builds on prior schemas

Constructing upon the ICD Schema work finished at Symantec, OCSF contains contributions from 15 further preliminary members together with: Cloudflare, CrowdStrike, DTEX, IronNet, JupiterOne, Okta, Palo Alto Networks, Rapid7, Salesforce, Securonix, Sumo Logic, Tanium, Development Micro and Zscaler.

Couphlin defined that, whereas there have been a number of requirements and initiatives round knowledge and cyber over the course of the previous decade together with STIX (Structured risk Data eXpressioin, a standardized XML programming language for cyber threats) and TAXII (for Trusted Automated eXchange of Indicator Data, a transport protocol for sharing of risk information throughout organizations), he’s shocked by the uptake price for OCSF.

“We have now seen a big acceleration of adoption of OCSF,” he mentioned. “For those who had requested me 12 months in the past after we had been right here, I’d have mentioned it’ll be a gradual, lengthy highway to traction as a result of requirements are robust and corporations are territorial. I simply realized that Barracuda, for instance, has already launched its first product that natively integrates with OCSF, so it has grown by orders of magnitude up to now yr. The massive elementary distinction over the previous 12 months is we will now level to merchandise and capabilities available in the market which can be OCSF compliant, which we didn’t have final yr.”
