What is SOAR (Security Orchestration, Automation and Response)?

Staying protected online isn’t a matter of deploying an antivirus and a firewall. Repelling modern threats requires a unified security strategy that can manage and mitigate security events when they emerge. Security Orchestration, Automation, and Response (SOAR) stacks are one of the best tools for managing security events. But what is SOAR exactly?

SOAR Explained

The term SOAR was originally coined by Gartner and is used to refer to tools that combine Security Orchestration and Automation (SOA), Threat Intelligence Platforms (TIP), and Incident Response Platforms (IRP) together to manage security threats. Essentially, a SOAR solution enables the user to take data from lots of disparate sources and view it in one location.

How SOAR Works

SOAR solutions are monitoring platforms that provide the user with a dashboard supplied with security data and metrics that have been compiled from lots of different systems within an organization. Combining data from disparate sources helps develop a more comprehensive view of threats, with automated detection and incident response.

Many of these tools use threat intelligence and AI to improve decision-making and help users respond to threats – automatically in some cases. Automated responses and more detailed diagnostics help reduce the time it takes to resolve security threats. SOAR platforms can be broken down into three main components:

• Orchestration
• Automation
• Response

Orchestration

Orchestration is the process of collecting data from different sources and putting it together inside one platform. Orchestration is useful in the cybersecurity context because it can be used to take data from different tools and technologies to provide a top-down perspective of security threats.

For example, a SOAR tool would use orchestration to generate alerts from many different data sources and put them in one list so that the user can easily manage them. Having security event data in one place makes vulnerability management much easier. Without a security orchestration tool, a security analyst would have to move between different systems to maintain a network.

Automation

The automation component of SOAR tools is designed to reduce the administrative burdens that network administrators and security analysts face when managing security events. Manually detecting and responding to cyberattacks is and ineffective. One person cannot realistically monitor a dozen systems that generate thousands of alarms throughout the day.

SOAR solutions use automated workflows, alerts, and responses to enable the user to automatically respond to security events. There are many solutions that can be configured to automatically shut down a device or user account if anomalous activity is detected.

Response

The response portion of a SOAR tool is concerned with incident management and enabling users to respond to security events effectively. Features like the dashboard are where most incident management and response activity takes place. From here the user can view alerts and threat intelligence to manage threats in real-time.

These tools provide root-cause diagnostics and intelligence to help the user find solutions to security events faster. In other words, SOAR tools have been designed to play a diagnostic function to help guide the user towards the best actions to take during remediation.

Why Is SOAR Important? Automated Threat Detection and Remediation

SOAR solutions have become more important in recent years as cyber threats have become more sophisticated. Cyber attackers are becoming more adept at identifying vulnerabilities and finding entry points to networks. As companies use more services like cloud services and applications there are more entry points to manage.

Managing disparate systems has been a consistent pain point for security analysts who are expected to switch back and forth between collecting data and monitoring security events. Trying to monitor all of these systems manually makes for a hefty workload that few can keep up with.

For example, a security analyst can have to wade through thousands of alarms on different infrastructure monitoring solutions. Manual tasks like managing alarms take time away from other more pressing concerns like monitoring for threats.

SOAR tools eliminate many manual tasks by automating the data collection process. Instead of changing between lots of different solutions the user can view the data compiled from TIPS and intrusion detection systems (IDS) in one location to identify cyber-attacks more efficiently.

Being able to view this data in an accessible format helps with detection and response. It also enables enterprises to become more data-driven and efficient. The depth of data available to support the analysis of attacks leads to a more complete viewpoint than a security analyst could deliver (and at a lower cost!).

SOAR vs SIEM: What’s the Difference and Which is Better?

As far security tools go SOAR and security information event management (SIEM) solutions share a couple of similarities. Both are hybrid solutions that collect data from a number of sources and play an important role in cybersecurity. However, they each have distinct roles to play.

A SIEM tool collects and aggregates log data from different systems within a network, including applications and devices. The SIEM then analyses the data obtained for anomalous activity and sends an alert to the user if it recognizes anything of risk to the network.

SIEM tools combine the capabilities of security event management (SEM) tools, which analyze log data in real-time and combine it with security information management (SIM), which collects and reports on security events.

The core difference between SOAR and SIEM solutions is that the former can respond to security threats whereas a SIEM can only detect them. SOAR solutions have automated responses ready to follow up whereas SIEM solutions can only issue alerts once a problem has been detected.

SOAR solutions are superior for automatic incident response and require less manual actions than a SIEM tool. While SIEM solutions are good at detecting cyber attacks, it can be challenging to keep up to date with the large volume of alerts that are generated (particularly when taking into account false positives).

Even though SOAR has better automation capabilities it can be useful to combine SOAR and SIEM solutions together. Whenever a SIEM solution creates an alert a SOAR solution can import that data so that it can easily be seen by an analyst. The analyst can then use the data provided by the SIEM solution to take a closer look.

SOAR Software

As with all cybersecurity solutions, SOAR platforms come in different shapes and sizes. Although the tools are built on the same foundations the experience provided by each varies tremendously. In this section we’re going to look at some of the top SOAR solutions on the market:

• Siemplify
• LogRhythm

Siemplify

Siemplify is a SOAR solution that pulls all your performance data from your SIEM and EDR tools in one place. The software can create a prioritized list of alerts from other software by using machine learning. The list shows you the alerts that are most threatening to your business operations. To speed up remediation you can then assign or escape cases so that they can be dealt with efficiently.

The user experience is also very high quality. You can easily view real-time metrics and KPIs in a variety of visual displays. For example, you can view an Alert Distribution pie chart, which breaks down what threats generated what alerts. Having this information makes it easy to see what your biggest security vulnerabilities are.

The software also enables the user to find the root cause of a security incident in a matter of seconds. You can view a visualization of the threat storyline to see exactly what triggered a security event. You can also collaborate with other employees and send messages inside the platform. Interactions are recorded so that you can easily use them in audits later on.

If you’re looking for a SOAR tool designed specifically to improve your response time then Siemplify is suitable for that purpose. To view a quote for Siemplify you will have to contact the company directly. You can sign up for the demo.

LogRhythm

LogRhythm is one of the most well-known SOAR solutions in the world. LogRhythm uses SmartReponse automation to automatically respond to security events after an alert. For instance, you can use an automated endpoint quarantine feature to identify network ports with suspicious devices and then remotely disable them.

Other automated responses include the option to suspend user accounts that are acting suspiciously or kill abnormal processes on critical devices. Having automatic threat response is useful because it means that your security analysts don’t have to resolve issues manually every time.

The visibility offered by LogRhythm is also second to none. You can create custom dashboards and view investigation and response activity in real-time. This perspective provides you with enough clarity to detect significant security events. If you see something suspicious you can click to view additional threat intelligence.

The Challenges of SOAR Implementation

While onboarding a SOAR solution is worth it, the challenges of implementation can be steep. A key challenge is finding a tool with a level of complexity that meshes with the experience of your employees. Some platforms are aimed at non-technical users and others are more advanced that require the expertise of an analyst to use.

It isn’t uncommon for some programs to require the user to have knowledge of programming languages like Perl or Python to integrate external data sources. Trying to deploy a technical solution in an environment without an experienced analyst would be a waste of time and money.

To adopt a new solution smoothly it is critical that you choose a platform that matches the technical abilities of your employees. Look for a tool that has a graphical user interface (GUI) and an integrated development environment (IDE). The former will allow non-technical users to interact with the platform and the IDE will allow analysts to write their own scripts.

Another massive challenge that companies run into is trying to automate everything at once. You can’t automate every manual task that your security analysts do. Trying to automate everything will complicate your entire threat resolution process. A much more effective strategy is to start automating smaller tasks that would usually be done by your analyst.

You should also be aware you will need to create a new incident response process from scratch. Onboarding a new monitoring tool drastically changes the incident response process.

When onboarding a SOAR platform the incident response process has to be redesigned so that employees can respond to security breaches quickly. The incident response process will need to be periodically revised so it stands up to the latest threats.

What is SOAR? An Automated Approach to Cybersecurity

Automation has become a must-have for larger organizations with large workloads. Modern networks are becoming too diverse and complex for security analysts to keep up with while relying on manual solutions. SOAR and other automation solutions are making network monitoring more efficient so that companies can stay protected.

Even companies using traditional network monitoring tools are struggling to manage the alerts they generate. When one missed alert could be the difference between a normal day at the office or a DDoS attack a serious update is needed. Switching to a SOAR solution can help to improve your incident response process and free up your security analysts!
