CASBs offer a centralized approach to managing security, helping organizations mitigate risks associated with cloud adoption.

Data leaks refer to unauthorized exposure of sensitive information. When viewed through a SaaS setting, these are data exposures emanating from a SaaS application. Data leaks can result in the compromise of personal, financial, or business-critical information. While some define data leaks as unintentional, the term is used interchangeably with data breaches.

The European Union’s Digital Operational Resilience Act (DORA) came into force on 16 January 2023, but organizations have until 17 January 2025 to become compliant. Financial institutions, including banks, insurance companies, and investment firms, must comply with the legislation’s strict rules for cybersecurity protection, detection, containment, recovery, and repair capabilities or face penalties. DORA was created by the EU to strengthen the operational resilience of its financial entities. The EU recognized that the digital transformation taking place in the financial services industry placed an unprecedented reliance on technology. Financial services would be impacted if that technology were compromised by a cyber attack. DORA covers Information and Communications Technology (ICT), which includes cloud-based SaaS applications.

Guest access to SaaS applications enables organizations to invite external parties to use their app environment. Guests can be clients, partners, vendors, freelancers, agencies, or outside firms who are invited to collaborate with an organization. SaaS applications used widely by enterprises for business-critical needs that enable guest access include Slack, Microsoft Teams, Google Workspace, Salesforce, GitHub, and Zoom.

An Identity Provider (IdP) is a trusted service that manages and verifies user identities within a system or across multiple applications. It serves as a central authority for authenticating users and granting them access to authorized resources. In other words, the IdP acts as a gatekeeper, ensuring that only authenticated and authorized users can access protected data and services.

Identity Threat Detection and Response (ITDR) is a set of security measures designed to detect and respond to identity-related security threats. ITDR adds a new layer to the identity fabric, enabling organizations to secure data even after their perimeter has been breached.

SaaS Identity Security refers to the set of processes and technologies used to manage and secure user identities and access to SaaS applications. It encompasses a range of activities, such as user provisioning, authentication, access control, and user lifecycle management, specifically tailored for cloud-based software services. The primary objective of SaaS Identity Security is to ensure that the right individuals have appropriate access to the right resources while maintaining security and compliance standards.

Identity Security Posture Management (ISPM) is the practice of securing an organization’s digital identities to prevent bad actors from accessing enterprise SaaS applications to carry out identity-related threats.

ISO compliance in SaaS security refers to adherence to the standards and requirements set forth by the International Organization for Standardization (ISO) for information security management systems. ISO has developed various standards, but the most relevant one for SaaS security is ISO 27001.

Companies rely on a multitude of SaaS applications for data storage, communication, project management, and customer experience, with these apps constituting 70% of total company software usage. As this reliance grows, ensuring their security becomes increasingly vital. However, the diverse nature of these applications, their dynamic environment, and various departmental management make securing them a challenging task. This article will look at the challenges of SaaS security and its rising importance among CISOs. It will offer practical advice on establishing a robust SaaS security strategy that strikes a balance between safeguarding applications and facilitating efficient user operations. The Challenges of SaaS Security Misconfigurations in SaaS applications are a major cause of breaches, as the complex and evolving nature of these settings, often with unique terminologies, makes it challenging to maintain security. Monitoring these configurations manually across numerous applications is practically impossible, leaving sensitive data exposed until the next audit. To mitigate this, organizations should establish a thick identity fabric with tools like Single Sign-On (SSO) and Multi-Factor Authentication (MFA) to enhance access security and detect threats even after a breach occurs, using Identity Security Posture Management. Users frequently integrate third-party apps into their SaaS stack without security team awareness, potentially granting intrusive permissions. Detecting and assessing these integrations is crucial for maintaining security. Moreover, the accessibility of SaaS applications from unmanaged and compromised devices poses significant risks, especially when high-privileged users are involved. Therefore, a robust SaaS security program should review device posture, associate devices with users, and manage these risks effectively. Identity-centric threats, such as identity-based hacking techniques, are increasingly common in SaaS environments. To prevent these threats from escalating into breaches, organizations must implement a sophisticated Identity Threat Detection & Response (ITDR) approach, which includes monitoring Tactics, Techniques, and Procedures (TTPs), detecting indications of compromise (IoCs), and identifying unusual User and Entity Behavior Analytics (UEBA) patterns. SaaS Security’s Rising Importance to CISOs The use of SaaS applications offers businesses various operational advantages, such as increased efficiency and cost reduction, but it also introduces a range of security risks that need to be addressed. Firstly, data protection is a paramount concern as SaaS apps handle sensitive customer, strategic, and financial data, and a security breach can lead to substantial financial losses, reputational damage, and loss of trust from customers and partners. Additionally, regulatory compliance, particularly with data protection regulations like GDPR and CCPA, is a compelling reason for implementing a robust SaaS security program, as non-compliance can result in significant financial penalties, especially in highly regulated industries like financial services. Collaboration within SaaS applications introduces third-party risks, making it crucial for businesses to establish a consistent security policy across all applications to monitor third-party vendors effectively. Many SaaS apps also enhance their functionality by integrating third-party applications, which may request high-risk permissions. This potentially opens the door to supply-chain attacks, necessitating careful monitoring. Moreover, ensuring strict access control measures within SaaS security is essential to manage the risks associated with anytime, anywhere access. While many of these threats existed in on-premises solutions, they have now evolved to target SaaS applications. A recent report indicates that SaaS incidents have become increasingly prevalent, with 55% of respondents having experienced a SaaS incident in the past 18 months. The most common incident types include data leaks, malicious applications, data breaches, SaaS ransomware, and corporate espionage or insider attacks. Moreover, many instances of SaaS applications contain files with malware waiting to be downloaded onto users’ computers, underscoring the importance of robust SaaS security measures. As a result, SaaS security now has the attention of the CISO. They are looking into best practices for securing their SaaS stack, evaluating existing tools, and looking at SSPMs as a potential answer to their SaaS security challenges. Kickstarting a SaaS Security Program Implementing a SaaS security program isn’t as simple as buying monitoring software and turning it on. SaaS is completely decentralized across organizations, to the point that many security teams aren’t aware of all the applications being run by their organization. It takes careful planning for a successful deployment. These are the main steps you need to take to get started. Mapping and Planning Map your Apps and Security Requirements Prior to establishing a robust SaaS security program, it’s crucial to begin by mapping your application landscape and understanding your specific security needs. While some widely-used SaaS apps like Salesforce or Microsoft 365 may have more critical data to safeguard, most smaller, task-specific applications used by smaller teams contain sensitive information, necessitating their inclusion in your security considerations. Furthermore, identifying relevant regulatory and compliance requirements, such as SOX for public companies and HIPAA for medical data, is essential. Addressing user access and data privacy requirements is vital, involving the assignment of user roles and adherence to the principle of least privilege to minimize potential attack vectors, data breaches, and unauthorized access. Additionally, if your applications handle personally identifiable information (PII), ensuring your SaaS security program protects this data and complies with privacy laws is imperative. Map Your Security Ecosystem A robust SaaS security program should be integrated tightly into the existing infrastructure for maximum effectiveness. This integration involves connecting with the organization’s Identity Provider (IdP) and single sign-on (SSO) provider to bolster user governance and restrict unauthorized access to the SaaS stack. These integrations not only enhance application protection but also facilitate the work of security professionals. Additionally, it’s crucial to integrate SaaS security tools with the existing SOC, SIEM, and SOAR tools to enable efficient analysis of alerts, event management, and automation of remediations and user deprovisioning, streamlining the efforts required to secure the SaaS environment. Identify Your Stakeholders Identifying stakeholders in SaaS security is a complex process, as business units primarily responsible for productivity and efficiency often prioritize workflow and collaboration over security. In contrast, security teams aim to secure company data but often lack insight into and access to new applications. The situation is further complicated by the unique language each SaaS application uses for its settings, making it challenging for security teams to provide user-friendly guidance for business teams. With numerous applications, each with multiple configurations and users, managing security settings becomes a formidable task. An effective SaaS security program necessitates collaborative efforts and compromises between these two groups to strike a balance between risk reduction and productivity enhancement. Onboard Stakeholders and Define Responsibilities Securing SaaS applications involves several key teams. The primary stakeholders are the app owners and the security team, but Central IT also plays a crucial role in SaaS security, managing elements like SSO, infrastructure, and hardware, which indirectly impact security through the management of Active Directory, IdP, and servers. Governance and Compliance (GRC) are responsible for enforcing organization-wide compliance, including within the SaaS stack, ensuring that application configurations align with company policy and industry-specific regulatory requirements, making them a vital stakeholder in SaaS security.

SaaS (Software as a Service) misconfigurations refer to the incorrect or insecure configurations of SaaS applications and services. These misconfigurations can expose sensitive data, compromise security, and lead to various vulnerabilities that attackers can exploit.

Multi-Factor Authentication (MFA), formerly known as Two-Factor Authentication (2FA) or Two-Step Verification, is a security mechanism that adds an extra layer of protection to the authentication process. Unlike traditional single-factor authentication (username and password), MFA requires users to provide multiple pieces of evidence to verify their identities.

NIST compliance refers to adherence to the standards and guidelines set forth by the National Institute of Standards and Technology (NIST), which is a non-regulatory agency of the United States Department of Commerce. NIST provides guidance, best practices, and standards for various areas, including information security, cybersecurity, and privacy.

The principle of least privilege (PoLP) is a widely recognized cybersecurity strategy that limits authorized access for each user entity to the minimum necessary to perform assigned tasks. A best practice for both human and non-human identities, adhering to the principle of least privilege helps protect corporate data and assets from threats by bad actors such as unauthorized access, data leakage, data breaches, and malicious malware attacks.

Risk management in SaaS refers to the process of identifying, assessing, and mitigating potential risks that could impact the security, compliance, and operational aspects of SaaS applications. It involves implementing strategies and controls to minimize the likelihood and impact of adverse events, ensuring the continuity and integrity of business operations in the cloud environment.

User authentication is the process of verifying the identity of a user attempting to access a system or application. It typically involves the user providing credentials, such as a username and password, which are then validated against stored records. Once authenticated, the user is granted access to the system or application, allowing them to perform authorized actions based on their level of permissions or privileges.

Understanding the concept of a Zero-Trust approach is essential to a holistic SaaS security program. Unlike traditional perimeter-based security models, Zero-Trust assumes that no user or device should be automatically trusted, regardless of their location or network environment. Instead, access to resources is continuously verified and authorized based on various factors, such as user authentication, device health, and contextual data. This approach minimizes the attack surface and ensures a higher level of security.
