Do More With Your SOAR

Running any Security Operations Center (SOC) is complex — and running without the best tools to automate as much as possible makes it even more difficult. File enrichment is one of the best ways to augment your hard-working SOC operators, and improve your success rate in identifying malicious malware before it becomes ransomware.

What Is File Enrichment?

File enrichment adds information to raw data to enhance its value, accuracy, and context. This process is critical in cybersecurity to improve threat detection and response. Here are some essential aspects of file enrichment.

Contextual Information

Metadata: Adding details such as file creation date, author, and modification history.
Behavioral Analysis: Insights into the file’s behavior, including any suspicious activities or patterns.

Reputation Scores

Trustworthiness: Assigning scores based on the file’s history and known associations with malicious activities.
Classification: Categorizing files as benign, suspicious, or malicious based on aggregated data.

Threat Intelligence Integration

Correlated Indicators: Linking file hashes with known indicators of compromise (IoCs) from threat intelligence feeds.
Historical Data: Providing information on past occurrences and behaviors of similar files.

Automated Analysis

Malware Detection: Using automated tools to scan and analyze files for malware signatures and anomalies.
Behavioral Profiling: Automatically profiling the file’s behavior to detect deviations from standard patterns.

By enriching file data, organizations can better understand potential threats, improve incident response times, and enhance security posture.

Why Invest In File Enrichment?

• Contextualization: File hashes without context are almost useless. Enrichment helps identify a threat’s origin, nature, and potential impact. For example, if you detect a suspicious IP address, enrichment can provide details about its geographic location, associated domains, and known malicious activities. Your SOC can automate many tasks, improving incident response time and accuracy.

• Reduction of False Positives: By adding context, enrichment helps to filter out irrelevant alerts, allowing security teams to focus on genuine threats. This is crucial for reducing alert fatigue and improving the efficiency of security operations. Your operators won’t spend all day doing repetitive, time-consuming tasks.

• Enhanced Incident Response: Enriched threat intelligence provides actionable insights to accelerate the investigation and mitigation of security incidents. For instance, knowing that a detected threat is linked to a known malware campaign can guide the response strategy. Your operators can respond to an incident consistently, regardless of skill level.

• Integration with Security Tools: Many security platforms, such as SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response) systems, use threat intelligence enrichment to enhance their detection and response capabilities. Your operators do not have to jump from tool to tool, cutting and pasting all day.

What Is Rich Context?

Rich context refers to the additional information and insights that help security analysts better understand and respond to threats. Here are some key aspects:

Attribution: Information about who is behind the threat, such as specific threat actors or groups and their known tactics, techniques, and procedures (TTPs).

Geolocation: Data about the threat’s geographic origin can help understand regional threat landscapes and targeting patterns.

Historical Data: Past occurrences of similar threats, including timelines and activity patterns, can indicate whether a threat is part of a more extensive campaign.

Associated Indicators: Related threat indicators, such as IP addresses, domains, file hashes, and URLs, can help identify the scope and scale of the threat.

Behavioral Analysis: provides insights into how the threat behaves, including its propagation methods, payloads, and potential impact on systems and networks.

Reputation Scores: Ratings or scores that indicate the trustworthiness or maliciousness of an entity based on aggregated data from various sources.

Reducing Human Error

Consistent formatting is a crucial feature of file enrichment. For example, malware is highlighted in red, good files are in green, and suspicious files are in yellow. While color marketing may seem obvious if your operators must go through several decision processes to make formatting consistent, human error and stress will cause them to make mistakes.

Automating most incident reporting in a consistent format will significantly reduce human error, speed up mitigation, and reduce operator fatigue.

ReversingLabs Integration

ReversingLabs has two main methods of connecting file enrichment API’s to your SOAR. Spectra Detect is our cloud-based solution. Spectra Analyze has the same capability but is an instance-based solution, either cloud-based but isolated or using an on-premise solution for the highest privacy and data protection level.

For further information, technical details, and documentation on the ReversingLabs integrations, see https://www.reversinglabs.com/integrations.
