Key Components of the Integration

The two advanced cybersecurity solutions are combined together in this app, each bringing its own unique strengths:

1. CloudSEK’s AI-Driven Risk Management and Threat Intelligence
   • ‍Utilizes 21+ specialized monitors through XVigil (Digital Risk Protection) and BeVigil Enterprise (External Attack Surface Management).
   • Provides deep, contextualized threat insights across diverse digital landscapes.
   • Offers early detection of emerging threats and vulnerabilities.
2. Splunk's Advanced SIEM Capabilities‍
   • Delivers industry-leading data ingestion, correlation, and analysis.
   • Enables rapid threat detection and response
   • Presents comprehensive security information through a unified interface

‍

By integrating these technologies, organizations can:

• Correlate external threat intelligence with internal log data for more accurate threat detection
• Automate response workflows based on high-fidelity threat indicators
• Gain a more comprehensive view of their security posture across multiple digital domains

‍

The 360-Degree Threat Protection Model

The CloudSEK x Splunk integration offers comprehensive protection across some of the key security domains:

• Web and Application Security: Real-time vulnerability detection in web applications, APIs, and mobile apps.
• Infrastructure and Network Security: Continuous monitoring of network, cloud, and DNS infrastructure for threats.
• Dark Web and Social Media Intelligence: Early warning system for planned attacks or data leaks.
• Code and Data Leak Prevention: Detection of sensitive data exposure in public repositories, open buckets, and cloud storage.
• Fraud and Impersonation Prevention: Rapid detection of phishing campaigns and brand impersonation attempts.
• Vulnerability and Exploit Intelligence: Real-time tracking of new CVEs and compromised assets.
• Banking and Financial Security: Monitoring for leaked financial information (credit/debit cards) and potential fraud attempts.

Let’s look at some of the use cases

‍

Scenario 1

A sophisticated fraud ring launches a coordinated impersonation attack against BigBank, a major financial institution, utilizing multiple channels to maximize their chances of success.‍

Attack Vectors Detected

• Fake mobile apps impersonating BigBank's official banking app.
• Phishing websites mimicking BigBank's login portal.
• Social media accounts impersonating BigBank's customer service.
• Fraudulent call centre operations claiming to be BigBank support.‍

Integration in Action

• CloudSEK XVigil Alerts:
  • Fake Mobile Apps Monitor identifies 3 counterfeit Android apps and 2 iOS apps in various third-party app stores and download sites, all impersonating BigBank's official app.
  • The Fake URLs and Phishing Monitor detects a network of 25+ phishing domains using slight variations of BigBank's official domain, all hosting convincing replicas of the bank's login page.
  • Fake Social Media Handles Monitor flags 12 Twitter accounts and 8 Facebook pages impersonating BigBank's official customer service channels.
  • Fake Call Center Monitor identifies a cluster of new VoIP or phone numbers that suddenly appeared in online advertisements and social media posts, claiming to be BigBank's official customer support lines.
• Splunk's correlation and analysis:
  • Observes a 200% increase in customer reports of suspicious calls, emails, and text messages in the last 48 hours. This correlation suggests a potential phishing scam targeting BigBank customers.
  • Detects an unusual pattern of password reset requests and new device registrations across genuine customer accounts.
  • Identifies a spike in failed login attempts on the real BigBank platform, suggesting credential stuffing using harvested information.
• CloudSEK-Splunk Integration projected response:
  • Generates a high-priority fraud alert correlating all detected impersonation attempts across channels.
  • Triggers a coordinated response playbook:
    • Automatically submits takedown requests for fake apps to respective app stores.
    • It initiates rapid domain blacklisting of phishing URLs across major ISPs and corporate networks.
    • Reports impersonating social media accounts for immediate suspension. 
    • Temporarily elevates authentication requirements for high-risk actions (e.g., large transfers, adding new payees) on genuine BigBank platforms.
  • Deploys targeted warning messages on BigBank's official app, website, and social media channels, alerting customers about the impersonation attempts and to stay vigilant against potential frauds.

‍

Scenario 2

CloudSEK’s BeVigil Enterprise Helps a Retail Company Prevent Customer Data Leakage from Their Cloud Environment.

Vulnerabilities Detected

• Cloud Storage Misconfiguration: BeVigil discovers a publicly accessible Amazon S3 bucket containing sensitive customer information, including personal identification data and transaction records.
• API Vulnerability: An API endpoint used for retrieving customer orders is misconfigured, allowing unauthorised access without proper authentication controls (CVSS Score: 9.1 - Critical).

Integration in Action

• CloudSEK BeVigil Alerts:
  • Flags the S3 Bucket: Identifies the publicly accessible S3 bucket as a critical misconfiguration exposing confidential customer data.
  • Historical Vulnerability Insight: Reveals that the misconfiguration has been exploitable for the past 45 days, potentially impacting thousands of customers.
  • API Vulnerability Detection: Highlights the insecure API endpoint lacking authentication, classifying it as a high-severity vulnerability due to the risk of unauthorized data access.

• Splunk’s Correlation and Analysis:
  • Anomalous API Traffic: Detects a sudden spike in API requests originating from suspicious IP addresses, indicating potential exploitation attempts of the vulnerable endpoint.
  • Threat Intelligence Correlation: Associates these IP addresses with known malicious actors and patterns identified by CloudSEK's threat intelligence, suggesting a coordinated attack.
  • Data Exfiltration Indicators: Monitors unusual download activities from the S3 bucket, signaling possible data exfiltration efforts.

• CloudSEK-Splunk Integration’s Response:
  • Comprehensive Security Alert: Generates a critical alert combining detailed information on the cloud misconfigurations and observed malicious activities.
  • Triggers a coordinated response playbook:
    • Restricts S3 Bucket Access: Immediately revokes public access permissions and applies proper access control lists (ACLs) to secure the bucket.
    • Secures API Endpoint: Disables the vulnerable API and implements robust authentication mechanisms, such as OAuth 2.0.
    • Initiates Security Audit: Notifies the security team and cloud administrators to conduct a thorough review of all cloud storage permissions and API configurations.
  • Remediation Guidance:
    • Credential Rotation: Advises rotating all access keys and credentials associated with the compromised services.
    • Data Encryption: Recommends implementing server-side encryption for sensitive data stored in S3 buckets.
    • Enhanced Monitoring: Suggests setting up advanced logging and continuous monitoring for cloud resources to detect future anomalies.
    • Customer Impact Report: Generates a detailed list of potentially affected customers for proactive notification, allowing the company to comply with regulatory requirements and maintain customer trust.
