Problem: Data and cloud costs are consuming security budgets

The rapid growth of data in cybersecurity operations, combined with the expanding reliance on cloud computing, has resulted in SIEM, data, and cloud costs consuming a sizable portion of security budgets. This financial burden not only limits organizations' ability to invest in essential security measures but also impedes their ability to proactively defend against ever-evolving threats.

Cyber attacks have become progressively more sophisticated and diverse, and threat actors are constantly adapting and improving their tactics, techniques and procedures (TTPs). Defenders must chase a moving target to keep up and be able to detect and respond to potential eventualities across a porous and expanding attack surface. Many security operations teams today manage a dizzying array of security and general-purpose data solutions to achieve the visibility they require, and especially to manage and make sense of the resulting flood of alerts. As organizations struggle to scale their infrastructure and processes to accommodate the growing data demands, they face the following additional challenges.

Limited resources

Data engineering teams are often assigned to help security operations with their data needs but are a scarce resource. Without a breach, security projects are often not the most critical business priority, leaving little time to consider efficiency or optimization.

Most security professionals have foundational knowledge of data technology and processes, but they are rarely proficient at data engineering, or even both. More importantly, any time they spend on wrangling data is time in which they are not hunting threats and actively protecting the business.

In addition, there is an ongoing and acute shortage of skilled security and data engineers and analysts, placing constraints on placing additional work on either security or data teams.

Compliance and privacy risks

Compliance and privacy risks are increasingly important concerns for organizations managing large volumes of sensitive data in their cybersecurity operations. Threat detection telemetry and other data that is relevant to security operations is often distributed across different solutions, technologies, cloud services and even physical locations, making it difficult to keep track of everything.

Businesses must navigate diverse regulations, and actively prevent data breaches, which means applying adequate data protection measures, such as pseudonymization, encryption, as well as managing the data lifecycle—from acquisition, through retention, and to disposal.

Increased data storage and management costs

Data computation and storage costs start small but can quickly snowball over time. Users often only recognize the Faustian bargain they made too late, when their data is already locked in, and difficult and expensive to export.

When data costs grow faster than the available security budget, security teams face a stark choice: What data can we afford to collect - and what can’t we afford to lose?

Costs also quickly spiral out of control if a need arises to collect and retain data over longer time frames, especially if data needs to be available on-demand for live searching or is frequently replayed into MLOps pipelines.

It is not unusual for security teams to run SIEM for event correlation and alert management, a security data lake for long-term historical investigation and hunting, and various cloud data storage and micro services for cheap data retention and special purpose analytics workloads. To gain a complete picture and respond to threats effectively, data must be moved between all these technologies, resulting in quickly mounting costs, especially without a coherent security data strategy.

Existing approaches fall short

Traditional security solutions are not designed to be data efficient, and generic data engineering tools, while powerful, require extensive customization and entail a steep learning curve to be repurposed for reuse in security operations.

These factors further strain budgets and divert funds from other critical security initiatives like improving incident response or deriving threat intelligence.

Considering these challenges, addressing the escalating costs and overheads associated with SIEM, data, and especially cloud computing has become a top priority for businesses seeking to maintain a robust cybersecurity posture. By finding innovative ways to optimize data management and reduce costs, organizations can not only alleviate financial pressure but also strengthen their security operations and better protect themselves against the ever-present threat landscape.

Security teams need innovative strategies and cost-effective technologies that can efficiently manage, process, and analyze vast amounts of data, while minimizing the associated expenses and overheads.

What about XDR?

Many organizations are adopting Extended Detection and Response (XDR) solutions to consolidate the number of technologies they need to operate and try to eliminate some of the complexity involved inherent in security operations.

Depending on the specific XDR offering, several security capabilities are usually consolidated. Endpoint detection and response (EDR), network detection and response (NDR), cloud detection and response (CDR), incident management, and threat intelligence are especially common.

XDR streamlines some security data needs, but most security teams will still need to run additional technologies and integrate with other systems. XDR is typically delivered as a cloud-hosted SaaS solution, with similar cost dynamics as cloud SIEM and data lakes.

Solution: SecDataOps and Tenzir Pipelines

Effective threat detection, investigation, and response increasingly means mastering data. Security teams require a new strategic approach that considers cost management and Financial Operations (FinOps) as primary outcomes: Security Data Operations (SecDataOps).

SecDataOps seeks to minimize data costs, whether computational or storage, while maximizing data utility and utilization. Controlling SIEM, cloud, and other data costs means being strategic and aggressive about what data is sent onwards, and in what shape.

Data Reshaping and reduction

A lot of information contained in security events is erroneous, repetitive, or otherwise data-sparse and easily compressed. By filtering, deduplicating, and compacting data at the edge before it reaches expensive consumption-based services and solutions, it is possible to achieve anywhere between 30% and 80% cost reduction. Moving the right data at the right time to the right place can drastically lower SIEM, Cloud and data costs.

Data compaction

Data retention policies are often based on simply aging out older data. Distinct types of data have different business and lifetime values. Instead of just deleting the oldest data, Tenzir's unique compaction algorithm applies aging based on the relative importance of the data.

We can also deploy aggregation pipelines to shrink data by choosing context over fidelity. For example, by converting flow records into an aggregate matrix of who communicated with whom, the data may shrink 10x in size but it's still possible to answer questions like "have we had communication with this entity?". This gracefully degrades the data fidelity and limits the utility, instead of abruptly throwing data away.

Data pre-processing and enrichment

Enriching alert, event, and telemetry data with user, asset, and threat intelligence context is often done on several occasions across different solutions. Similarly, executing detection content, such as Sigma rules, is also often repeated in many instances. Pushing enrichment and detection content execution down to the network edge eliminates duplicate effort, processes data where it’s most cost-effective and ensures that the same enriched data is available consistently for any workloads.

Conclusion

Tenzir's innovative SecDataOps approach and Security Data Pipelines offer an innovative approach for organizations seeking to balance their cybersecurity needs with financial constraints. By optimizing data management, reducing SIEM, cloud, and data costs, and streamlining operations, businesses can allocate more resources to proactive threat hunting and incident response.
