How SOC Teams Benefit From SOAR Automation
Posted on: November 09, 2020
Security operations and incident response teams are often stretched thin, and technology that is designed to support their efforts can at times add more work. Whether an organization has cloud solutions, on-premise, or a hybrid, they should be empowered to be more strategic with their workload and focus on priority initiatives through technology, not hindered by it.
For SOC and IR teams, automation by way of security orchestration, automation, and response (SOAR) solutions are one of the fastest ways to reduce time spent on low priority work and cutting out false positives, leaving attention to be focused on threats to the organization.
What is SOC Automation?
SOC automation or security operation center automation is designed to streamline processes and displace what is considered tedious tasks. These can range from enriching data associated with a case or incident, reviewing numerous false positives, and manually responding to threats. This also includes sending out notifications or reaching out to users, which in itself is a time-consuming task.
SOC Automation Use Cases
Being able to automate processes and workflows for the SOC team has many benefits, and each step of their daily routine can be mapped back to each. Alerts and reported incidents take a lot of manual time, especially when a majority are considered false positives or benign. Even with some technology in place, many SOC teams get alert fatigue. To reduce this, automation is put in place to enrich the data, collect relevant evidence, and follow up with the related user.
Data Enrichment and User Communication
For enrichment, a SOAR solution can compare the details to other known or reported incidents both internally and externally via feeds. The enriched data then automatically moves false positives to a closed state, which already cuts more than half of the necessary time out of the process. SOC automation can also add enrichment by pulling evidence such as the relevant URL and details about the user. Lastly, if a user reported an incident or triggered one, the system can automatically contact them via email or out-of-band communication such as SMS.
Automatically Close Cases or Flag for Review
Phishing threats in particular make up a large number of cases, and SOC automation can tackle the majority of it. If the incident comes up as benign or a false positive, the case is automatically closed. If it contains an executable file, macro, or malicious link, an automated workflow can flag an analyst to review it further.
One of the areas where analysts typically get involved in the SOC automation process is to further investigate an incident. Once SOAR has pulled relevant IOCs, which typically connects to a solution such as a SIEM, further evidence is collected regarding the user. This can range from device in play, recent web history, and other relevant details. And only then does an analyst need to review the information to decide on the necessary response.
Once an analyst determines if an incident is a threat, they can run playbooks to manage the appropriate response. Rather than manually blocking a URL or deleting a malicious email, various SOC automations can handle the process.
Lastly, so other SOC team members or security teams can learn from a case or incident, SOAR can also collect the relevant information and place it into a knowledge base.
Benefit of SOAR Automation for SOC
In addition to streamlining processes and making SOC and IR teams more efficient, SOAR automation results in:
- Time savings and efficiency gains
- Free up analysts for more advanced work
- Increased visibility and decreased time to detect
- Consistent processes and workflows
This is accomplished by a mixture of machine-speed touchpoints such as enriching data to see if a reported incident is benign or confirmed, having a dashboard to quickly see relevant charts and data points such as open tasks, having a system manage the workflow and processes so that human error is removed, and the time to detect a threat doesn’t depend on a person reviewing the information or the time spent investigating it. Ultimately the goal of added automation to SOC processes is to make teams more efficient and reduce burnout.
