Learn how to Use Databricks to Increase Your SIEM and Meet the Federal OMB M-21-31 Mandate


On August 29, 2021, the U.S. Workplace of Administration and Finances (OMB) launched a memo in accordance with the Biden Administration’s Govt Order (EO) 12028, Bettering the Nation’s Cybersecurity. Whereas the EO mandates that Federal Companies adapt to in the present day’s cybersecurity menace panorama, it doesn’t outline particular implementation tips. Nevertheless, the memo (M-21-31) describes a four-tiered maturity mannequin for occasion administration with detailed necessities for implementation. M-21-31 requires Federal Companies to satisfy every rising stage of maturity utilizing their present cybersecurity finances.

Early conversations with Federal Companies have proven that their projected log assortment storage necessities will improve by an element of 4-10x. Since many Companies use legacy Safety Info and Occasion Administration (SIEM) platforms to gather and monitor their logs, they’re dealing with a large improve in each the licensing and infrastructure price for these options so as to meet the mandate.

Fortuitously, there’s another structure utilizing the Databricks Lakehouse Platform for cybersecurity that Companies can use to rapidly, simply, and affordably meet M-21-31 necessities with out forklifting operations or filtering the required uncooked logs. On this weblog, we’ll focus on this structure and the way Databricks can be utilized to enhance present SIEM and Safety Orchestration Automation and Response (SOAR) implementations. We can even present an summary of M-21-31, the drawbacks of legacy SIEMs for fulfilling the mandate and the way the Databricks method addresses these points whereas bettering operational effectivity and lowering price.

Bettering investigative and remediation capabilities

Why is M-21-31 being issued now? Latest large-scale cyberattacks together with SolarWinds, log4j, Colonial Pipeline, HAFNIUM and Kaseya, spotlight the sophistication, complexity and growing frequency of cyberattacks. Along with costing the Federal authorities greater than $4 million per incident in 2021, these cyber threats additionally pose a big threat to nationwide safety. The federal government believes steady monitoring of safety information from an Company’s complete assault floor throughout, and after incidents, is required within the detection, investigation and remediation of cyber threats. Company-level safety operations facilities (SOC) additionally require safety information to be democratized to enhance collaboration for more practical incident response.

Maturity mannequin for occasion log administration

The maturity mannequin described in M-21-31 guides Companies via the implementation of necessities throughout 4 occasion logging (EL) tiers: EL0 – EL3:

The maturity model described in M-21-31 guides Agencies through the implementation of requirements across four event logging (EL) tiers: EL0 - EL3.

The expectation is for Companies to right away start to extend efficiency to succeed in full compliance with the necessities of EL3 by August 2023. The primary deadline got here in October 2021 when Companies needed to assess their present maturity towards the mannequin and establish resourcing and implementation gaps. From there, Companies are anticipated to attain tiers one via three each six months. Logging necessities and technical particulars by log class and retention interval are offered for every kind of knowledge within the memo. Virtually throughout the board, retention interval necessities are 12 months for energetic storage and 18 months for chilly information storage.

What’s an company to do?

How does an company go about assembly each the M-21-31 and SOC necessities specified within the memo? Typically talking, M-21-31 is demanding that Chief Info Safety Officers (CISOs) develop log assortment by what many are measuring as 4-10x present ingest ranges. The variety of information sources being collected is increasing together with the retention, or lookback, interval. In an effort to fulfill the mandate, the primary query it is advisable to reply is, what number of terabytes of knowledge does your company ingest every day? From there, you possibly can decide the elevated licensing price of your present SIEM, elevated infrastructure price and associated administration prices. As this Complete Value of Possession (TCO) for legacy SIEMs is instantly associated to information ingest, the price of enlargement for an present structure may very well be important.

Conventional SIEM vs. SIEM augmentation

M-21-31 didn’t include a lot warning and is an unfunded mandate. Companies want an answer that may be carried out with present sources and finances. Some Companies are discovering that the TCO of increasing their present SIEM to extend licensing, storage, compute, and integration sources would price tens of tens of millions of {dollars} per 12 months. This price solely will increase if the legacy structure is on-premises and requires further egress prices for brand new cloud information sources.

SIEM augmentation utilizing a cloud-based datalLakehouse takes the advantages of legacy SIEMs and scales them to help the excessive quantity information sources required by M-21-31. Open platforms that may be built-in with the IT and safety toolchains present alternative and adaptability. A FedRAMP accepted cloud platform permits you to run on the cloud setting you select with stringent safety enforcement for information safety. And integration with a scalable and highly-performant analytics platform, the place compute and storage are decoupled, helps end-to-end streaming and batch processing workloads. No overhauling operations, particular experience or excessive prices. Simply an augmentation of the safety structure you’re already utilizing.
