Security Information and Event Management


We are living in the age of the data breach. As of June 30th, 2015, there have been over 400 data breach incidents in 2015, putting us on track to eclipse 2014's record high 783 data breaches.

The average cost of those breaches? $3.79 million, according to research from the Ponemon institute. And, beyond the immediate financial cost, data breaches can cause an unquantifiable loss in customer confidence.

But IT organizations aren't just fighting hackers and malware—they're also battling a torrent of data from their own networks. Information is pouring in. A fortune 500 enterprise's infrastructure can easily generate 10 terabytes of plain-text data per month. Logs, threat intelligence feeds, forensics, IAM– if improperly managed these systems can create such a deluge of data that many enterprises end up underwater while the pertinent security data floats by.

So how can enterprises effectively log, monitor, and correlate that data to obtain actionable insight? Enter the Security Information and Event Management (SIEM) solution.

Coined by Gartner analysts Mark Nicolett and Amrit Williams in 2005, SIEM is, in simple terms, a security solution that combines Security Event Management (SEM), which focuses on log collection and report generation, with Security Information Management (SIM), which focuses on analyzing real-time events using event correlation and event mechanisms.

SIEM solutions help enterprises manage the increasing volumes of logs coming from disparate sources and lessen the damage of sophisticated cyber-attacks by proactively monitoring networks for suspicious activity in real-time.

Traditionally, SIEM is deployed for two use cases: threat management: the real-time monitoring and reporting of activity and access, or Compliance reporting, which helps businesses meet stringent compliance requirements such as HIPAA, PCI DSS, SOX, and more.

However, as information security has evolved, so have SIEM capabilities. Today's SIEM systems are quickly embracing new capabilities such as behavioral analytics, which can help enterprises detect potential threats and eliminate them before they turn into costly breaches.

In 2016, SIEM is seen as a necessary part of any significant enterprise security effort, but choosing the right SIEM solution for your organization isn't easy. SIEM has a reputation as a complex and convoluted product, and implementation is a daunting process that can take weeks or even months to complete. Rush that process and you could end up with massive cost overruns or worse, an expensive, failed deployment.

To complicate things further, SIEM is a mature market full of vendors capable of meeting the basic log management, compliance, and event monitoring requirements of a typical customer, but whose points of differentiation may not be obvious to the untrained eye. However, as similar as they may seem, many SIEM solutions are optimized for drastically different use-cases, and one size almost never fits all.

This guide includes both pure SIEM solutions and more specialized solutions, as a full-blown SIEM may not be the best option for an organization. We've also included the new-guard— Big Data Analytics security platforms such as Splunk.

When evaluating the 24 solutions listed in this guide and others not listed, it's important to consider the tradeoffs that come with each kind of solution. Will you be focused on compliance or threat detection or incident response? Do you want a solution that comes prebuilt for today's threats, or one that, through customization, can adapt to new threats? What kind of solution does your team want? What can they handle? These are the questions you need to ask yourself.

Whatever your decision, one thing is certain: whether you are a publicly traded corporation, a government institution or even a small to medium-sized business, the benefits of SIEM are worth investigating today. In this Buyer's Guide there's a solution for everyone, from small groups to multi-national organizations.

Solutions Review is not in the business of picking winners and losers in a technology solution sector; we'll leave that to others. Our job is to help you get started evaluating providers. In this Buyer's Guide, we've selected 24 SIEM and Security Analytics solutions as a way to narrow things down a bit for potential buyers.

In order to help you start the process of sorting all this out, below are 10 questions, five for yourself, and five for a prospective solutions provider to your SIEM needs. These questions will help you walk through what you want in a solution, what it's supposed to do for you, as well as evaluating the solution's offerings, services and staying power.

Questions You Should Ask Yourself Before Selecting an SIEM Solution


How will we support our SIEM Solution?

SIEM only works if you work it, and a typical SIEM deployment can require a team of up to eight full-time employees to properly manage it. SIEM without a dedicated team of security analysts is like an empty castle: it may seem imposing, but it's not stopping anybody. SIEM is not a substitute for a security department, it's a tool, and it needs a good technical expert and ongoing to work properly and deliver value. Before considering which SIEM is right for you, make sure your organization is prepared to properly manage one. Do you have the resources and personnel to effectively manage SIEM? Can you hire and train the staff necessary to support SIEM? If not, you may be better off considering a managed services offering.


What does my organization want to get out of SIEM?

It may seem obvious, but you must know your requirements when evaluating SIEM or Security Analytics solutions. Before beginning the evaluation process you should rank your needs and your business drivers for adopting SIEM. What data sources do you need to log? Do you need real-time collection? Do you need to collect all security data or just a subset? What do you need to archive? For how long? How will you use data once collected? For Forensics? Detecting threats? Auditing and Compliance?


Do we need a full SIEM solution? Or is log management sufficient?

SIEM systems are highly capable, but they're also costly and complex. If your organization is window shopping for complex SIEM solutions without a complex use case, then you may want to reconsider. For example, many regulatory compliance requirements can be met with traditional log management solutions. If you find yourself more concerned with log management than with correlation, SEM, and SIM, this may the right move for you.


Do we need 'Security Analytics' or traditional SIEM?

"Security Analytics" solutions, which leverage big data technologies and new analytic algorithms, are making a major impact on the SIEM market. They are extremely effective solutions, but they are also quite complicated. Organizations with mature, well-funded and dedicated security operations teams should investigate these kinds of solutions, which can recognize security threats better and reduce the workload on the analysts tasked with monitoring your systems. Be wary, though—if your organization is having trouble with its current SIEM deployment, it's doubtful that you could handle a big data security analytics system. As Gartner Analyst Anton Chuvakin has said, "do not pay for the glamour of big data if there's a low chance of benefiting from the investment."


How much are we willing to spend?

Enterprise SIEM requires a significant budget. There are the initial license costs, often arranged as base price plus user or node, there are database costs for servers, the costs of training personnel, and often additional external storage. Then there's the ongoing cost of the personnel required to operate a SIEM effectively. A full-blown, enterprise-grade SIEM system can cost your business hundreds of thousands of dollars when all is said and done, and while that will give you top-of-the-line capabilities, not all business are capable of spending that kind of money. Some SIEM vendors offer a lightweight version that gives basic log management and reporting capabilities without the advanced analytic capabilities and other features that other SIEMs support. These lightweight SIEMs are considerably less expensive to acquire than other SIEMs, and could be a good alternative for businesses looking to save money.

And 5 Questions You Should Ask Your Potential SIEM Solution Provider


How will your product meet our auditing and regulatory compliance needs?

Compliance management is one of the most frequent use cases for SIEM solutions, and as such, most SIEMs have built-in support for the most common compliance efforts, such as HIPAA, PCI DSS, and SOX. Your organization can save time and resources by using a SIEM to meet its compliance reporting requirements, but before you can do so you need to make sure that a potential solution is compatible to your specific industry regulations.

Ask your potential vendor to demonstrate a clear relationship between your industry compliance needs and their policies and rule sets. What out-of-the-box compliance reports are available?

What level of customization is available for reporting?


Do you offer assistance with deployment? What about training for personnel?

SIEM is a complex technology, and so naturally, SIEM deployment is a complex process. In fact, SIEM is notoriously difficult to deploy-- In a 2014 Report, Gartner analyst Oliver Rochford estimated that somewhere between 20% and 30% of SIEM deployments among his client base fail. Once successfully deployed, a SIEM solution requires a dedicated team of skilled analysts and technicians to manage the software and ensure effective use. Ask prospective vendors what kind of support they will provide during the deployment process, and what, if any, training is available for your team.


Do you support public and private cloud platforms and big data environments? If not, do you have plans to do so?

Whether you're there yet or not, there's a strong chance that Public Cloud Computing and Big Data Solutions will play a prominent role in the future of your organization's IT environment. If you're spending top dollar on an SIEM solution today, you'll want to know that it will integrate with the systems you use tomorrow. Ask prospective vendors how their solutions support cloud and big data platforms that you currently use, or may use in the future.


How well does your SIEM handle the log sources? Is there extensive native support, or will custom development work be required?

Your SIEM isn't worth much if it can't understand the log data from the important log-generating sources in your organization. Make sure your potential SIEM solution supports your organization's security systems, such as firewalls, intrusion prevention systems, VPNs, email gateways, and antimalware products.

Any prospective SIEM solutions should also support log files from the operating system (both type and version) that your organization uses.


What features does your product provide for data analysis?

Aside from the SIEM's alerts and reporting, an SIEM used for incident detection and response should provide features that help your security analysts review and analyze log data.

Even the smartest, best-configured SIEM is worse than the best analyst--a highly accurate SIEM can still misinterpret events, so make sure your team can vet the SIEM's results. Strong search and data visualization capabilities can also help facilitate the investigation of incidents.
