From my Gartner Blog - Our SIEM Assessment paper update is out!

The results of our “summer of SIEM” are starting to come up; our assessment document on SIEM (basically, a “what” and “why” paper, that sits besides our big “how” doc on the same topic) has been updated. It has some quite cool new stuff aligned to some of our most recent research on security analytics, UEBA, SOC and other things that often touch or is directly related to SIEM.

Some cool bits from the doc:

“Organizations considering SIEM should realize that using an SIEM tool is not about procuring an appliance or software, but about tying an SIEM product to an organization’s security operations. Such an operation may be a distinct SOC or simply a team (for smaller organizations, a team of one) involved with using the tool. Purchasing the tool will also be affected by the structure and size of an organization security operation: While some SIEM tools excel in a full enterprise SOC, others enable a smaller team to do security monitoring better.”

“While some question SIEM threat detection value, Gartner views SIEM as the best compromise technology for a broad set of threat detection use cases. Definitely, EDR works better for detecting threats on the endpoints, while NTA promises superior detection performance on network traffic metadata. However, network- and endpoint-heavy approaches (compared to logs) suffer from major weaknesses and are inadequate unless you also do log monitoring. For example, many organizations dislike endpoint agents (hence making EDR unpalatable), and growing use of Secure Sockets Layer and other network encryption generally ruins Layer 7 traffic analysis.”

“UEBA vendors have been frequently mentioned as interesting alternatives due to their different license models. While most SIEM vendors base their price on data volumes (such as by events per second or gigabytes of data indexed), these solutions focus on the number of users being monitored irrespective of the amount of data processed. This model has been seen as a more attractive model for organizations trying to expand their data collection without necessarily changing the number of users currently being monitored. (Note that UEBA vendors offer user-based pricing even for tools addressing traditional SIEM use cases.) UEBA products have also been offered as solutions with lower content development and tuning requirements due to their promised use of analytics instead of expert-written rules. This makes them attractive to organizations looking for an SIEM tool but concerned with the resource requirements associated with its operation. The delivery of that promise will, however, strongly depend on the use cases to be deployed.”

As usual, please don’t forget to provide us feedback about the papers!

 

 

Next wave of research: SOAR, MSS and Security Monitoring use cases! Here we go :-)

From my Gartner Blog - SOAR research is coming!

As Anton anticipated on this post, we’ll be writing about SOAR – Security Orchestration, Automation and Response – tools. Of course many people, seeing this coming from Gartner, will think: “oh great, here are those guys creating new fancy acronyms for silly markets with a bunch of VC powered startups”. Yes, I agree that usually that’s the feeling. But let’s consider a few FACTS:

  • Some of these new vendors have already been acquired by big players such as FireEye (Invotas), Microsoft (Hexadite) and Rapid7 (Kommand). So, it seems that what they are offering is interesting enough to be integrated into other security technologies out there.
  • We often complain about the lack of skilled manpower in security. It is a very common issue to put together SOC teams. And whenever lack of manpower becomes an issue, AUTOMATION is a potential solution.
  • We also like to complain about the ever growing number of security tools being used by organizations. How can you properly integrate them so you can actually get the full value from them? You have tools to detect threats on the network, but you need to investigate those alerts on the affected endpoints using your EDR tool; with so many moving parts in place, some ORCHESTRATION is definitely required.
  • Finally, we also keep saying organizations are not reacting fast enough to incidents. Again, one of the most common ways to do things faster is streamlining processes (WORKFLOW) and leveraging AUTOMATION.

So, the need for the capabilities is there. We may argue that they should be embedded in current tools or that they are not complex enough to require a new product, just a bunch of Python or Powershell scripts. For the first point yes, this could definitely help the integration, but if you use the automation capabilities from each tool individually you may end up with “automated spaghetti workflows”, what would become a nightmare to support, troubleshoot and maintain. A hub and spoke approach can help keeping the complexity manageable. What is that hub? SOAR! Can it be done purely with scripts? Well, I bet you can replicate a lot of these products capabilities with some clever scripting, but how many organizations have people to do that and want to have more code to support, troubleshoot and maintain?

There are other interesting things related to SOAR that we want to explore: is this the new “single pane of glass” for the SOC? Does it make sense to leverage Machine Learning on these use cases? Are organizations looking for the glue only or for content (playbooks)? Some of the things we have in our minds for this upcoming and exciting research project.

So, of you are a SOAR vendor, don’t forget to schedule a Vendor Briefing with us! You can find more details here.

From my Gartner Blog - Our new Vulnerability Assessment Tools Comparison is out!

Vulnerability assessment is usually seen as a boring topic and most people think the scanners are all equal – reaching the “commodity” status. Well, for basic scanning capabilities, that’s certainly true. But vulnerability scanners need to stay current with the evolution of IT environments; think all the changes in corporate networks in the past 20 years due to virtualization, mobility, cloud, containers and others. Those things certainly affect vulnerability management programs and how we scan for vulnerabilities. These IT changes force scanners to adapt, and we end up seeing some interesting differences at the fringes. Our new document, “A Comparison of Vulnerability and Security Configuration Assessment Solutions”, compares the 5 leaders of this space (BeyondTrust, Qualys, Rapid7, Tenable and Tripwire) and show how and where they differ.

Some of the capabilities where we found interesting differences are:

  • Agent based scan
  • Integration with virtualization platforms
  • Integration with IaaS cloud providers
  • Mobile devices vulnerability assessment capabilities
  • VA on containers
  • Delivery models (on-prem, SaaS)

 

As we’ve been doing, please consider providing feedback on the paper; this helps us improve our research :-)

From my Gartner Blog - SIEM, Detection & Response: Build or Buy?

As Anton already blogged (many times) and twitted about, we are working to refresh some of our SIEM research and also on a new document about SaaS SIEM. This specific one has triggered some interesting conversations about who buy services and who buy products, and how that decision is usually made.

There are usually some shortcuts to find out if the organization should look, for example, for a MDR service or for a SIEM (and related processes and team to manage/use it). They are usually related to the organization’s preference for relying on external parties or doing things internally, the availability of resources to manage and operate technology or some weird accounting strategy that moves the needle towards capital investments or operational expenses. But what if there’s no shortcut? What if there’s really no preference for either path, how should an organization decide if it should rely on services for threat detection and response, or if it should build those capabilities internally? Making things more complicated, what if the answer is a bit of each, how to define the right mix?

Initially I can see a few factors as key points for that decision:

  • Cost – What option would be cheaper?
  • Flexibility – Which option would give me more freedom to change direction, put less restrictions on how things could/should be done?
  • Control – Which option gives me more control over the outcome and results?
  • Effectiveness – Which option will provide me, for lack of a better word, “better” threat detection / response capabilities?
  • Time to value – Which option can be implemented and provide value faster?

(Yes, there are other factors, including the security of your own data, but many times those factors end up in the “shortcuts” category above. Stuff like “we don’t put our stuff in the cloud”; makes the decision really easy, but that’s not the point here.)

Some of these factors have clear winners: time to value is almost always better with services, while doing everything yourself will obviously give you more control than any type of service.

Flexibility is more contentious. Services will be less flexible as no service provider (apart from pure staff augmentation) will give you the option to define how every piece of the puzzle should work. However, building things and hiring people will often freeze your resources more than just paying a services monthly bill. If you build everything in a certain way and then decide to change everything, you’ll probably have to pay some things twice. Moving from one service provider to another can be easier when contracts are made for flexibility.

And what about the last point, which model will provide the best results? If you are a Fortune 100 company, you’ll probably be in a position, in terms of resources, context and requirements, to build something that will be better than any service provider will be able to do for you. But if you’re not in that category, the best service providers will probably be able to give you better capabilities that you would be able to build AND maintain; just think about the challenge of keeping a very good and motivated team for more than a few months!

A simple framework for deciding between outsourcing or building in house could just look at those 5 factors, but you didn’t think the problem was that easy, right? Because the decision IS NOT BINARY! Today you can fully outsource your security operations, outsource some processes or even keep processes and people and rely on tools provided in a SaaS model. The number of questions to ask yourself and factors to consider grows exponentially.

For now we are just looking at a very specific outsourcing point, the SIEM as a tool. We hope to build some type of decision framework as one of the outcomes of our current research, but I’d like to revisit the broader problem in the future. And you, how did you decide between build or buy your detection and response capabilities?

From my Gartner Blog - Apresentando no Gartner Security Summit Brasil 2017

(excuse me for the post in Portuguese…)

O Gartner Security & Risk Management Summit de São paulo está chegando! Já estou no Brasil para o evento, que acontece entre os dias 8 e 9 de Agosto. Tenho algumas apresentações durante os dois dias de evento, incluindo o keynote de abertura, junto com meus colegas Claudio Neiva e Felix Gaehtgens. São estas:

Gerencie Riscos, Construa Confiança e Abrace a Mudança Tornando-se Adaptável em Todos os Lugares
08/08/2017 – 09:15AM

Augusto Barros , Claudio Neiva , Felix Gaehtgens

Neste keynote de abertura, o Gartner vai introduzir um novo capítulo para a segurança da informação, que irá transformar todas as áreas de segurança da informação a partir de então. Com base na visão de arquitetura de segurança adaptativa do Gartner, este keynote ampliará a capacidade e a necessidade de ser continuamente adaptável a todas as disciplinas de segurança da informação. Esta abordagem será a única maneira em que a segurança da informação será capaz de equilibrar as exigências em rápida mudança dos negócios digitais com a necessidade de proteger a organização de ataques avançados, mantendo níveis aceitáveis de risco e conformidade. Exploraremos essa visão futura e usaremos exemplos do mundo real sobre como essa mentalidade se aplicará à sua organização de segurança da informação e risco, processos e infraestrutura.

Mesa-redonda: Compartilhando Experiências com serviços MSS e MDR
08/08/2017 – 13:45

Muitas organizações estão confiando em Serviços Gerenciados de Segurança (Managed Security Services) e Gestão de Detecção e Resposta (Managed Detection and Response) para melhorar sua postura de segurança. O valor desses serviços, no entanto, está diretamente relacionado ao modo como a relação com o fornecedor é gerenciada. Esta discussão irá focar nas melhores práticas e eventuais armadilhas na contratação e utilização dos serviços MSS e MDR. Questões-chave:

• Quando faz sentido confiar nos provedores de serviços de segurança para detecção e resposta de ameaças?
• Como decidir entre MS SP e in house?
• Quais são os cenários de falha comuns para cada modelo?
• Quais são as melhores práticas para gerenciar o relacionamento com o provedor de serviços?

Aplicando Deception para a Detecção e Resposta a Ameaças
08/08/2017 – 16:00

Deception está surgindo como uma opção viável para melhorar recursos de detecção e resposta a ameaças. Esta apresentação tem como foco o uso de deception como um método de “baixo atrito” para detectar movimentos de ameaças laterais e como uma alternativa ou um complemento a outras tecnologias de detecção.

Workshop: Desenvolvimento, Implementação e Otimização dos Casos de Uso de Monitoramento da Segurança
09/08/2017 – 09:15

Esse workshop terá como foco, por meio da colaboração com pares, a implementação e a otimização dos casos de uso de monitoramento da segurança. Os participantes serão orientados pela estrutura do Gartner para identificar e refinar os seus requisitos a fim de produzir os seus próprios casos de uso de monitoramento da segurança com base em seus desafios e prioridades atuais.

Mesa-redonda: Lições Aprendidas Sobre Aventuras de Analytics de Segurança
09/08/2017 – 13:45

Muitas organizações se aventuraram além do SIEM e aplicaram técnicas e abordagens de análise avançada à segurança. Esta mesa redonda é uma oportunidade para as organizações com iniciativas de análise de segurança compartilhar suas descobertas e expor seus desafios atuais sobre como torná-lo efetivo.
Quais são seus casos de uso atuais?
Que ferramentas estão sendo usadas?
Quais são as habilidades envolvidas (e necessárias)?

From my Gartner Blog - Update to our Vulnerability Management Guidance Doc

Our updated Vulnerability Management Guidance document has just been published. It is a refinement to the guidance framework we created a couple of years ago. The focus on this one was to include additional information on the scope of VM programs, prioritization of vulnerabilities and use of mitigation actions when remediation cannot be applied. It is very pertinent considering the whole WannaCry thing that happened a few weeks ago.

Some interesting bits from the paper:

  • Scoping:

New technologies with a high number of devices being left out of the traditional VM processes may suggest that those processes are obsolete and about to be replaced by other approaches, such as mitigation and patch-independent controls (e.g., application whitelisting or isolation). It’s important to remember, however, that legacy IT and legacy approaches are here to stay. While cloud adoption, DevOps and other IT delivery disrupters are happening, IT inertia is a powerful force, and in many regards a large chunk of the future will look just like the past. Similarly, the “scan and patch” cycle is here to stay for a diminishing but still very large share of IT.

  • Prioritization:

The definition of a prioritization method for your organization depends on a few factors: from the size and complexity of the environment to the context data available. Prioritization must allow an organization to maximize the use of the available remediation and mitigation capacity and achieve maximum possible risk reduction. For example, if 1,000 vulnerabilities are found during the latest scan and there is IT operations bandwidth to fix 100 to 150 of them (depending on the specifics of the vulnerable systems), the main reason for prioritization would be to identify the set to be acted on to reduce the risk by aiming for reduced incident likelihood and reduced potential incident cost.

  • Mitigation actions:

Given that organizations today face multiple challenges with patching vulnerabilities in software and code running on various devices (ranging from printers to mobile phones to IoT devices), mitigation measures (also sometimes called “shielding”) are growing in importance.

[…]

 Mitigation measures are often defined as temporary solutions to be used until the vulnerability is remediated, but for some scenarios, they might end up being permanent solutions. For example, a web application developed by a contractor may have vulnerabilities that simply cannot be fixed by the organization, since the original contractor may not be available anymore. In this case, a web application firewall (WAF) may become a permanent mitigation measure. Some vendors even call this “virtual patching” to hint at a permanent nature for such “fixes” at some organizations.

 

And as we’ve been doing for all our papers, please provide feedback with your thoughts/suggestions here.
