Navigating the SaaS Security Landscape: Defender for Cloud Apps Takes Center Stage
In the dynamic world of cloud computing, software as a service (SaaS) applications have become ubiquitous across hybrid work environments. Protecting these SaaS apps and the critical data they store has emerged as a significant challenge for organizations. The surge in app usage, coupled with employees accessing company resources outside the traditional corporate perimeter, has introduced new attack vectors that demand a comprehensive security approach.
Microsoft Defender for Cloud Apps, formerly known as Cloud App Security, has evolved to address these evolving security concerns. As a leading cloud access security broker (CASB) solution, Defender for Cloud Apps now delivers full protection for SaaS applications, empowering security teams to monitor and safeguard cloud app data across a range of advanced features.
Foundational CASB Capabilities: Visibility, Governance, and Compliance
At its core, Defender for Cloud Apps provides the fundamental CASB functionality that organizations have come to rely on. This includes:
- Shadow IT Discovery: Identifying all the cloud services being used across the organization, including those that may have been deployed without IT’s knowledge.
- Cloud App Usage Visibility: Gaining detailed insights into which apps are being used, by whom, and how they are being accessed.
- App-Based Threat Protection: Safeguarding against threats that originate from within cloud apps, such as malware or compromised user accounts.
- Information Protection and Compliance Assessments: Ensuring that sensitive data stored in cloud apps is properly classified and protected, and that the organization’s cloud usage aligns with regulatory and industry standards.
Elevating Security Posture with SaaS Security Posture Management (SSPM)
While foundational CASB capabilities are essential, security teams face the challenge of needing to research best practices for securing each individual SaaS application. Defender for Cloud Apps addresses this pain point by incorporating SaaS Security Posture Management (SSPM) features, enabling security teams to improve the organization’s overall security posture.
Streamlining Posture Assessments
Defender for Cloud Apps evaluates discovered apps against more than 90 risk indicators, allowing security teams to efficiently sort through the identified applications and assess the organization’s security and compliance posture. This comprehensive assessment process provides visibility into potential misconfigurations or vulnerabilities, and delivers tailored recommendations to strengthen the security posture of each connected app.
Automating Posture Improvements
Defender for Cloud Apps automatically surfaces misconfigurations and suggests specific actions to enhance the security settings for each SaaS application. These recommendations are based on industry standards, such as the Center for Internet Security, as well as best practices defined by the app providers themselves. By automating this process, security teams can quickly and effectively improve the organization’s overall security posture across its SaaS ecosystem.
Integrating with Microsoft Secure Score
The SSPM data generated by Defender for Cloud Apps is seamlessly integrated into Microsoft Secure Score, providing a holistic view of the organization’s security posture across both cloud and on-premises environments. This integration empowers security teams to prioritize and address the most critical security issues, optimizing their overall security posture.
Advancing Threat Protection with Extended Detection and Response (XDR)
While cloud apps continue to be a prime target for adversaries seeking to exfiltrate corporate data, sophisticated attacks often involve a multi-modal approach. Attackers may start with email as the initial entry point, then move laterally to compromise endpoints and identities before ultimately gaining access to in-app data.
Defender for Cloud Apps addresses this challenge by integrating directly with Microsoft Defender XDR, the company’s comprehensive extended detection and response solution. This integration enables powerful correlation of signals across the Microsoft Defender suite, including endpoints, identities, email, and SaaS apps.
Achieving Full Kill Chain Visibility
By integrating SaaS security into the Microsoft Defender XDR experience, security operations center (SOC) teams gain full visibility across the entire attack kill chain. This enhanced visibility allows them to prioritize investigations, streamline response efforts, and ultimately protect the organization more effectively.
Improving Operational Efficiency
The integration of Defender for Cloud Apps into the Microsoft Defender XDR solution improves operational efficiency for SOC teams. By leveraging the correlated signals and incident-level detection, investigation, and response capabilities, teams can respond to threats more quickly and effectively, ultimately enhancing the overall security of the organization.
Safeguarding OAuth-Enabled Apps: Closing the Gap on App-to-App Security
The rise of OAuth-enabled applications has introduced a new attack vector that often goes unnoticed. These apps can have extensive permissions to access data in other applications on behalf of an employee, making them susceptible to compromise.
Defender for Cloud Apps addresses this gap in OAuth app security by introducing new capabilities to help organizations govern the apps used within their environment and maintain app hygiene.
Gaining Visibility into Unused Apps and Expired Credentials
Defender for Cloud Apps leverages Azure Active Directory to provide security teams with visibility into unused apps and expired credentials. This enables teams to identify potential vulnerabilities and take immediate action to resolve these risks, reducing the organization’s attack surface.
Automating App Governance and Credential Management
Defender for Cloud Apps allows security teams to set predefined policies to automatically monitor and manage unused apps and expired credentials. This streamlines the process of maintaining app hygiene, ensuring that only authorized and actively used apps have access to sensitive data and resources.
Integrating Microsoft Purview for Comprehensive Data Protection
Defender for Cloud Apps seamlessly integrates with Microsoft Purview, the company’s comprehensive information protection and compliance solution. This integration enables security teams to leverage out-of-the-box data classification types in their information protection policies, ensuring that sensitive data stored in cloud apps is properly identified and protected.
Enhancing Data Loss Prevention (DLP) Capabilities
Defender for Cloud Apps leverages Microsoft’s expansive suite of data loss prevention (DLP) capabilities to safeguard sensitive information, regardless of where it is accessed or stored. By connecting to SaaS apps and scanning for files containing sensitive data, organizations can implement robust controls to prevent unauthorized access or exfiltration.
Aligning with Regulatory and Industry Standards
The integration of Defender for Cloud Apps with Microsoft Purview enables security teams to align their cloud app data protection efforts with relevant regulatory and industry standards. This helps organizations maintain compliance and mitigate the risk of data breaches or unauthorized access.
