What is a SIEM, and why does
my organization need a SIEM?

SIEM stands for Security Information and Event Management. A SIEM is a hardware, software, or cloud-based tool that Information Security professionals use to log and store data, detect threats, gain security visibility, and meet various compliances in their IT environment. Gartner originally coined the term in 2005 to help organizations improve IT security visibility and vulnerability management.

"The goal of SIEM is to aggregate log data from various sources, correlate that data, and provide visibility, alarms, reports, and dashboards to the end-user."

Castra + SIEM Technology

Castra has a deep understanding of SIEM technology, and we've seen their evolution since the early 2000s before the term was coined. We've deployed SIEM in over 2,500 organizations worldwide, ranging from small organizations to global enterprises.

All of our deployments had two reasons they purchased SIEM:

Meet compliance
Improve Security Visibility

All 2,500 SIEM deployments revolved around those two reasons, with compliance being the main driver. Taking a trip down memory lane of Gartner's Magic Quadrant for SIEM over the past decade tells an exciting story… Mainly a tale of fragmentation and failure.

We bend platforms to work in your environment.

The reality is most
SIEM deployments
and vendors fail.

Building a SIEM product is very challenging. The level of complexity is deep and constantly evolving. First-time SIEM buyers and even experienced SIEM users have a tough time keeping up with the market due to the incredibly dynamic nature of cyber-attacks and new detection capabilities.

If you have not been using a SIEM for the past 20 years - and have not tested almost every SIEM platform on the market - you will be at a disadvantage trying to navigate the saturated SIEM market.

The majority of SIEM deployments that fail are not 100% due to the vendor. Most organizations have minimal resources or expertise when choosing, buying, deploying, or managing a SIEM. If you also purchased a SIEM without an experienced team odds are your SIEM deployment will be a failure.

SIEM technology is only as valuable as the practitioner using it.

As a result of SIEM failure, Managed Security Service Provider (MSSP), Managed Detection and Response (MDR), and Security Operation Center as a Service (SOCaaS) emerged and have grown at an aggressive rate for the past decade. However, not all MDR's are equal!

MSP's pretending to be a MSSP/MDR...

They run it the same way they run their NOC.
They treat it as a swivel chair.

When an alarm comes in to the Castra SOC:

In-Depth Analysis

We go through the timeline of events to understand "is there anything malicious?" or was this a simple user error?
In many cases, many of these other companies' work is as simple as forwarding an alarm. The notification can be accomplished with an email stating, "We have something. We're going to look at it, study it, then decide how to escalate."

Tuning

If another MSSP “tunes” it could just mean they are learning to auto close repetitive alarms.
We tune granularly, excluding the specific scenarios that are causing false positives without blinding ourselves to similar attacks.
We're not just going to turn it off because it makes noise.
We know how best to use rules/models, and we keep a record of it for all customers and situations.
All incidents and alerts are not equal.
We improve the accuracy and scoring of individual vendor data source feeds.

Customization/Content

An ever growing library of custom "Best Practices" rules and content.
100+ visualizations, searches, and dashboards BEYOND what vendors provide out of the box.
Custom roles prevent people from accidentally making mistakes, including our staff (follows the security best practice of "least privilege.")

Threat Hunting

Castra uses advanced Threat Intelligence used for investigations.
Improving Threat Intelligence lookups in the SIEM via curated feeds from Anomali Threatstream.
Analyst use of Anomali suite of tools to assist with Incident Triage and verification.
If we learn something from any environment, we apply it to all other platforms.
