SOAR: coordination for cyber security
SOAR (Security Orchestration, Automation and Response) technology helps coordinate, execute and automate activities between people and tools, enabling companies to respond quickly to cyber security attacks. The aim is to improve their overall security position. SOAR tools use playbooks (strategies and procedures) to automate and coordinate workflows which may include security tools and manual tasks.
How does SOAR help in the security field?
1. Combining security orchestration, intelligent automation, incident management and interactive investigations in a single solution.
2. Facilitating team collaboration and enabling security analysts to take automated actions on tools across their security stack.
3. Providing teams with a single centralized console to manage and coordinate all aspects of their company’s security.
4. Optimizing case management, increasing efficiency by opening and closing tickets to investigate and resolve incidents.
Why do companies need a SOAR?
Modern companies regularly face many challenges and obstacles when it comes to fighting cyber threats.
A first challenge is represented by an ever increasing volume of complex security threats. Furthermore, the security tools involved very often struggle to talk to each other, which is in itself a nuisance.
Such a large amount of data and software can only mean a large number of security alerts. In fact, there is too much threat intelligence data to allow teams to manually classify, prioritize, investigate and target threats. Furthermore, the work of security officers involves very specific skills and with increasing demand it is increasingly difficult to find a sufficient number of security officers to carry out the work.
System implementation
SOAR helps companies address and overcome these challenges by enabling them to:
– Unify existing security systems and centralize data collection to achieve full visibility.
– Automate repetitive manual activities and manage all aspects of the accident life cycle.
– Define incident analysis and response procedures, as well as leverage security playbooks to prioritize, standardize and scale response processes in a consistent, transparent and documented way.
– Quickly and accurately identify and assign the severity levels of incidents to safety alarms and support the reduction of alarms.
– Identify and better manage potential vulnerabilities in a proactive and reactive way.
– Direct each security incident to the analyst best suited to respond, while providing features that support easy collaboration and monitoring between teams and their members.
Practical applications
Below I wanted to list some practical examples of how a SOAR comes into action in certain situations.
Alarm management
Enrichment and Phishing Response: Activating a Playbook. Automation and execution of repeatable activities such as triage and involvement of interested users. Apply an extraction and control of indicators to identify false positives, then request activation of the SOC for a standardized response at scale.
Endpoint Malware Infection: Extracting threat feed data from endpoint tools and enriching that data. Cross-reference between recovered files and hashes with a SIEM solution, notify analysts, clean up endpoints, and update the tools database.
Failed User Login: After a predefined number of failed user login attempts, evaluating whether a failed login is genuine or malicious, a SOAR can activate in various ways. First of all by putting into practice a playbook, involving users and then analyzing their answers, then also the expiring passwords and finally closing the process.
Threat hunting
Indicators of Compromise (IOC): Take and extract indicators from files, track indicators through intelligence tools and update databases.
Malware Analysis: Verify data from multiple sources, extract and delete malicious files. A report is then generated and checked for malice.
Cloud Incident Response: This is done through the use of data from cloud-focused threat detection and event logging tools. The data is then unified between the cloud and on-premises security infrastructures, correlated thanks to a SIEM. The indicators are then extracted and enriched, to then check for the presence of malice. A final step of human control to the analysts who review their information update the database and close the case.
The benefits of a SOAR
Basically, a SOAR implements working methods and protocols of action in the system for fighting against cyber threats of a company. This significantly improves operational efficiency and accelerates incident detection as well as response times, which are effectively standardized.
A SOAR increases analysts’ productivity and allows them to focus on improving security instead of performing manual tasks.
By exploiting and coordinating the existing security technology investments in a company, it is possible to make a real difference.
