Reduce downtime and move from reactive to proactive monitoring.

The increase in the number and complexity of cybersecurity threats and attacks in the last several years is continuing to heavily influence enterprise security decisions. As well as seeing the growing business need, the significant benefit that Security Orchestration, Automation and Response (SOAR) technology can offer security operations and incident response teams is now truly being realized.
The complexity of cyber attacks has increased the need for organizations to share threat intelligence information within different areas of the business, and today may even include external stakeholders such as law enforcement or government agencies, to enable them to detect, contain and mitigate the constant and diverse cyber attacks that are occurring. Choosing the right SOAR tool can bring significant added value to an organization’s security operations, not only in terms of full incident lifecycle automation, (including triage, notification, context enrichment, hunting and investigation, as well as threat containment), but it can also enable incidents to be detected, responded to and mitigated more efficiently than ever before, ultimately becoming a force multiplier, enabling security teams to do more, respond faster, all with fewer resources.
It is key for any security team to ensure the security tools, technologies and platforms they implement are best suited for their infrastructure, workflows, processes, and procedures. Every setup likely varies from organization to organization. So, what questions should you be asking yourself as a security manager or CISO when it comes to selecting the appropriate SOAR solution? It is important to perform research, evaluate the tools, and request a proof of concept before you invest in any SOAR tool. Here, we will cover 5 fundamental areas that should be considered as part of the process.
Incident response teams are now in constant defense mode as the number of security alerts being generated is hitting an all-time high. In addition to the increasing and advancing threat challenges, many security teams now face a lack of skilled workforce that can efficiently react, investigate and collect the necessary threat intelligence to properly determine the impact of an attack, then contain and remediate it. It is no secret that there is a lack of skilled cybersecurity professionals in the industry, but this fact is also well known by attackers. A skilled analyst will know exactly what information is needed to assess a situation and quickly eliminate the attack by containing and remediating the threat. Humans, even when very skilled, do have limitations on how fast they can react and access, collect, analyze and correlate the information to gather proper threat intelligence.
Therefore, it is important to assess your resources and answer key questions including: Are all your alerts being responded to, or are they falling along the wayside? Are analysts overworked and suffering from alert fatigue? Would it be more effective and efficient for them to be working on higher-level prioritized tasks, as opposed to basic, mundane, repetitive ones that could potentially be automated? If the answer is yes to any of these questions, then some form of automation would make a significant impact on the operational performance of your security team.
When analyzing a SOAR solution, you should also consider one that enables both human actions and automated machine actions to work hand in hand simultaneously. Dual-action will enable you to automate the menial, repetitive tasks, but also ensure those tasks that need human intervention can also easily be actioned.
The average security team uses somewhere between 10 to 15 key security tools from third-party security vendors, including tools such as system information and event management (SIEM), intrusion prevention system (IPS), endpoint detection and response (EDR), malware sandboxes, and threat intelligence. A SOAR tool should easily integrate with these third-party technologies to provide bi-directional support for a number of different actions to expedite the incident response process. The selected SOAR tool should not only support cybersecurity standards and best practices, but also APIs and interfaces to other tools which would be beneficial. The tool should also support queries into databases to facilitate obtaining enrichment information. Widely used communication methods, such as Syslog and email should be supported as they allow the transmission of data from a large number of third-party tools.
It is crucial to evaluate the security tools currently in use and ensure they are capable of being integrated into the SOAR platform, which will ultimately be used to orchestrate and automate these security tools.
SOAR vendors that endeavor to ensure their products and solutions follow industry best practices and standards, such as ISO, NIST, CERT, SOA, COBIT, OWASP, MITRE, OASIS, PCI, HIPAA, offer the best products, factoring these into the planning, architecture, design and build development stages.
Vendors who are able to think ahead of the curve and have the ability to cater for a range of industries and their respective compliance, regulations, and standards across worldwide locations offer the best solutions, as large enterprises need to meet their day to day business needs as well as their security needs. One example is the upcoming Global Data Protection Regulation (GDPR) where breach notification is required within 72 hours. Your SOAR solution needs to be able to cater to this need and ensure it can provide a complete and user-friendly incident report as needed for varying levels of stakeholders.
When choosing a SOAR solution, it is important to make a list of all the regulations, standards, and best practices that you need to meet and ensure the SOAR provider can address these requirements.
The price of a SOAR solution can be a significant consideration. Most SOAR products are charged per number of users per license per year, but you need to ensure there are no extra hidden costs associated, especially for those that are complex and may require professional services to be deployed.
Questions that should be asked include:
One factor that is often overlooked is the price to feature ratio. Remember to evaluate which features will actually be needed versus which would be nice to have or simply won’t be utilized. Select a vendor that can offer affordable tools with no hidden costs and are willing to offer a license and maintenance price that works well for your budget and requirements.
As mentioned above, product support often comes at a price, so it is important to establish what support is included in the base price. Being able to obtain a high level of service and support from the SOAR vendor is an important consideration from the perspective of the success of the rollout, assessing the overall cost and day-to-day maintenance. Some of the questions that should be asked here are:
Support costs can significantly drive up the cost of deployment and should be assessed in the early stages of the procurement process as it is important to establish how much can be achieved directly by the security analysts and engineers internally. Security team managers and CISOs have to ultimately measure the increase in the performance of security operations and justify the return of investment received.
Overall, deciding whether or not to implement a SOAR solution should come down to the pure facts and figures from analyzing your current security operations performance against a number of KPIs and metrics and identifying the business need for it. Will it solve your common pain points and challenges such as a lack of skilled resources, the increasing number of alerts, etc. In most cases, the answer will be yes!
Weighing up the SOAR solutions out there then becomes the harder challenge. It is worth reviewing Gartner’s approach to SOAR, as well as making a list of requirements that you know must be covered to effectively work within your current and future infrastructure, those that are nice to have and those that are not so important to you. Overall though, the solution needs to be easy to implement, scalable, cost-effective and something that will enhance the overall performance of the security operations, improving the efficiency and effectiveness of the way incidents are managed.
