Mastering Security Automations

Understanding the Types of Security Automations

As a follow up on our blog posts around SADLC and Unified IR, Detection Eng and Automation process we wanted to share some insights on the next step, so let’s say you got your SOAR or Hyperautomation platform, you have all processes and integrations in place and now you are at the moment ok we start building automations , how do we organise them so we don’t end up with 200+ automations from which 50% are doing same or similar processing.

You might be thinking about automation playbooks for SecOps, DevOps, or security engineering (IAM, guardrails, cloud posture), but there are broader categories as following:

• Context Enhancement Automations

• Supportive Task Automations

• Orchestration Automations

Let’s explore what each type means and how they can enhance your security operations.

1. Context Enhancement Automations

Definition: Context Enhancement Automations involve enriching raw security data with additional context. This context, sourced from both internal and external sources, is essential for making informed decisions and improving the overall accuracy of threat detection and response efforts.

Examples:

• Threat Intelligence Integration: Automatically enriching security alerts with data from threat intelligence feeds. This provides context on indicators of compromise (IoCs), such as known malicious IP addresses, URLs, or file hashes, enabling more accurate threat identification and prioritization.

• Geo-IP Data Enrichment: Adding geographical information to IP addresses. This helps identify potential threats from specific regions, providing critical insights into the origin of attacks and helping to tailor defensive strategies based on regional threat profiles.

• User and Entity Behavior Analytics (UEBA): Enhancing logs with user behavior insights. By analyzing normal and anomalous behavior patterns, UEBA helps detect unusual activities that may indicate a security breach, such as unusual login times or access to sensitive data.

• Host Context Building: Augmenting logs with additional data points that provide context to alerts or specific behaviors. This can include information like user roles, device types, or historical activity patterns, helping analysts quickly understand the potential impact and severity of an alert.

• Incident History: Enriching alerts with historical context based on similar data points observed in past incidents. This helps in identifying recurring threats and understanding the effectiveness of previous responses, guiding more informed decision-making.

Benefits:

• Improved Accuracy in Threat Detection: By adding relevant context to raw data, these automations enhance the precision of threat detection mechanisms, reducing the likelihood of false positives and false negatives.

• Enhanced Context for Faster Decision-Making: With enriched data, security analysts have access to comprehensive information that enables quicker and more accurate assessments of potential threats, leading to faster response times.

• Reduction of False Positives: Providing additional data points helps differentiate between benign and malicious activities, significantly reducing the number of false positives that analysts need to investigate.

• Leaner Analytic Rules: Automation allows for simpler and more efficient analytic rules. For example, some query languages may not support complex operations directly, necessitating multiple data iterations. By applying context-enhancement automations, these rules can be simplified, reducing complexity and potential execution errors.

2. Supportive Task Automations

Definition: Supportive Task Automations, also known as Utility Automations or Sub-Playbooks, are essential helpers that support more complex automation workflows. These automations handle routine and repetitive tasks, ensuring that foundational processes run smoothly and efficiently. While they might not be used often as standalone solutions, their true power is realized when combined with enrichment playbooks to build comprehensive end-to-end automation workflows.

Examples:

• Automated Ticketing: Automatically creating and updating incident tickets in response to security alerts. This ensures that incidents are logged promptly and accurately, facilitating efficient tracking and management of security events. Automated ticketing also helps in maintaining consistent documentation, which is crucial for compliance and auditing purposes.

• Isolating or Quarantining Suspicious Files: Grabbing suspicious files from endpoints detected by Endpoint Detection and Response (EDR) systems or from email mailboxes. This step is vital in preventing the spread of malware and enabling further analysis in a controlled environment. Automation here reduces the time taken to isolate threats, minimizing potential damage.

• Malware Sandbox Submissions: Automating the submission of suspicious files to various malware analysis sandboxes and retrieving the analysis results. This allows for quick and thorough examination of potential threats using multiple analysis engines, enhancing the accuracy of threat detection and response.

• Isolating Cloud Hosts: Automatically isolating specific cloud hosts for analysis and retrieving related configurations or additional logs. This process is crucial when a cloud resource is suspected of being compromised, ensuring that it is contained while further investigation and remediation actions are taken.

• Updating Block Lists: One of the most common response actions is to update block lists on email protection solutions or firewalls. Automated updates ensure that identified threats are promptly blocked across the network, reducing the risk of repeated attacks from the same sources. This automation also maintains consistency and reduces the likelihood of human error in manual updates.

• Generating Reports: Automating the generation of recurring reports for managers and various teams. These reports might include security metrics, incident summaries, or compliance status updates. Automated reporting ensures that stakeholders receive timely and accurate information, supporting informed decision-making and strategic planning. It also frees up significant time for security analysts who would otherwise spend hours compiling these reports manually.

Benefits:

• Increased Efficiency and Productivity: By automating repetitive and time-consuming tasks, security teams can allocate their time and resources to more critical and complex issues.

• Reduced Risk of Human Error: Automation ensures consistent execution of tasks, minimizing the chances of mistakes that could occur with manual processes.

• Consistent Execution of Routine Tasks: Automated processes follow predefined protocols, ensuring that tasks are performed the same way every time, leading to reliable and predictable outcomes.

• Reduction of Tedious Tasks: Offloading mundane tasks to automation tools reduces the operational burden on security teams, improving job satisfaction and allowing analysts to focus on higher-value activities.

• Reliable and Repeatable Flows for Reporting: Automation ensures that reports are generated consistently and accurately, enhancing the reliability of metrics and supporting better management decisions.

3. Orchestration

Definition: Orchestration Automations involve coordinating and integrating various enrichment and supportive task automations to create comprehensive, end-to-end processes for responding to security incidents. This approach aligns with the principles of the Security Automation Development Lifecycle (SADLC), ensuring that Incident Response (IR) procedures are both efficient and scalable. By orchestrating multiple processes and systems, these automations provide a holistic and integrated response to security threats.

Examples:

• Phishing Email Handling: Orchestrating the entire lifecycle of a phishing email incident by combining enrichment and supportive task automations:

  • Detection and Reporting: Automating the detection of phishing emails and streamlining the user reporting process.

  • Data Gathering: Automatically gathering Indicators of Compromise (IoCs) and malware samples from reported emails.

  • Analysis: Submitting samples to sandbox environments and cross-checking with threat intelligence feeds to ascertain the threat level.

  • Response: Responding to the reporting user, quarantining the email to prevent further spread, and updating block lists to prevent future occurrences.

  • Remediation: Blocking the IoCs across various security controls and logging all actions for compliance and auditing purposes.

• Vulnerability Management for Product Teams: Orchestrating an end-to-end automated workflow for vulnerability management by integrating enrichment and supportive tasks:

  • Data Parsing: Automatically parsing scanning data according to team-defined standards.

  • Notification: Sending detailed vulnerability reports to the Vulnerability Management (VM) team.
