In today’s highly distributed workplace, every employee has the ability to act as their own CIO, adopting new cloud and SaaS technologies whenever and wherever they need. While this has been a critical boon to productivity and innovation in the digital enterprise, it has upended traditional approaches to IT security and governance. Nudge Security is the world’s first and only solution to bring
Analysis Summary
# Tool/Technique: Nudge Security (SaaS Management Security Solution)
## Overview
Nudge Security is described as the world's first and only solution that unifies discovery, security, spend management, third-party risk management, and identity governance for Software as a Service (SaaS) applications adopted within an organization. Its primary purpose is to gain visibility into the full SaaS footprint, secure new accounts, manage identities, and mitigate third-party risk associated with the distributed workplace.
## Technical Details
- Type: Tool (SaaS Security Posture Management / Discovery Platform)
- Platform: Cloud/SaaS Infrastructure (Integrates via read-only API access to Microsoft 365 or Google Workspace)
- Capabilities: SaaS discovery (including shadow IT), OAuth grant security, security posture checks on Identity Providers (IdPs), spend management, and third-party risk assessment.
- First Seen: Based on article date, information is contemporary as of December 11, 2024.
## MITRE ATT&CK Mapping
Since Nudge Security is a defensive/management tool, its relevance to adversarial techniques lies in the areas it monitors and secures. Potential mappings relate to the discovery and credential access that adversaries seek:
- **TA0006 - Credential Access**
- **T1552 - Unsecured Credentials** (Monitoring for unsecured SaaS credentials or overly permissive OAuth tokens)
- **TA0007 - Discovery**
- **T1087 - Account Discovery** (Monitoring for new/unapproved user accounts accessing shadow SaaS apps)
- **TA0005 - Defense Evasion** (Monitoring for configurations that aid evasion, like email forwarding rules)
## Functionality
### Core Capabilities
- **SaaS Discovery:** Identifies all SaaS accounts, including shadow IT, GenAI apps, and duplicates, by analyzing machine-generated email messages (e.g., no-reply emails) via read-only API access to M365/Google Workspace.
- **Security Posture Checks:** Assesses security settings in the primary IdP (M365/Google Workspace) for risks like missing MFA/SSO, unrestricted groups, and problematic email forwarding rules.
- **Spend Management:** Discovers historical SaaS spend (up to two years) to identify unused or redundant paid accounts.
### Advanced Features
- **OAuth Governance:** Uncovers and catalogs all OAuth grants, assigning risk scores to identify overly permissive scopes. Allows for rapid revocation of risky grants.
- **Identity Risk Monitoring:** Flags suspicious email rules, inactive privileged accounts, and delegated inbox access.
- **Third Party Risk:** Provides security profiles for SaaS vendors, including breach history and compliance attestations, and maps the vendor's own SaaS supply chain.
- **Automated Workflows:** Supports orchestration for identity governance tasks, such as nudging users to enable MFA or automating account removals for unused licenses.
## Indicators of Compromise
*Note: As a defensive tool, Nudge Security itself does not generate typical malicious IOCs. Below are IOCs that it aims to detect or govern.*
- File Hashes: N/A (Agentless cloud solution)
- File Names: N/A
- Registry Keys: N/A
- Network Indicators: Focuses on API connections to M365/Google Workspace endpoints; no C2 servers associated with the tool itself.
- Behavioral Indicators: Detection of new SaaS sign-up confirmation emails; network communication indicative of unusual OAuth scope acquisition; creation of forwarding rules in M365/Google Workspace.
## Associated Threat Actors
Nudge Security is a commercial enterprise solution designed to defend against threats actors who exploit poor SaaS governance, including cybercriminals, state-sponsored actors, and insider threats attempting credential theft or data exfiltration via compromised SaaS applications.
## Detection Methods
Detection relies on analyzing API logs and email metadata from the integrated IdP:
- **Signature-based detection:** Not applicable for discovery; efficacy relies on API parsing rules.
- **Behavioral detection:** Monitoring for the creation of new, unapproved SaaS accounts indicated by confirmation emails; sudden changes in OAuth permissions or scopes; and configuration drift in IdP security settings.
- **YARA rules if available:** N/A.
## Mitigation Strategies
- **Prevention:** Implementing mandatory SSO/MFA integration for all SaaS applications.
- **Hardening Recommendations:** Auditing and restricting OAuth scopes, especially those granting high levels of data access (e.g., email or directory read access); immediately revoking grants from inactive users; enforcing data governance policies on permitted SaaS usage.
