SaaS Security Checklist: 9 Best Practices to Try

How to expose shadow IT, eliminate SaaS sprawl, and take control of your supply chain.

What is SaaS security, and why does it matter?

SaaS (Software as a Service) security is all about protecting your organization from cyber threats that can sneak in through SaaS applications. Companies are increasingly relying on SaaS tools to streamline operations, so robust security practices have never been more important.

‍

As cybersecurity threats evolve and become more sophisticated, organizations need to keep pace with the ways they protect their systems from these advanced threats.

‍

That’s why SaaS security is so important. It is a critical part of the overall security strategy for modern organizations that want to keep their application data safe from malicious attackers, yet still allowing users access at the same time.

‍

Following best practices, such as implementing a cloud security architecture framework along with adhering to SaaS industry standards, can help ensure that an organization’s application data remains secure.

‍

What are the best practices for strong SaaS Security?

To protect your application data, following the latest SaaS security best practices is always a great strategy. But a solid security strategy needs to go beyond the basics, incorporating risk assessments for third-party vendors, real-time user activity monitoring, strong authentication protocols, and routine vulnerability scans.

‍

When drawing up your SaaS security plan, think about both external (customers) and internal (employees) access to your systems. Controlling access privileges, enforcing strong passwords, and implementing multi-factor authentication (MFA) are just a few of the ways to improve your security posture.

‍

Don’t forget to follow industry standards, which provide a framework for reducing risks and ensuring compliance. 

‍

Here is a list of best practices to get you started. 

  1. Use SaaS Security Posture Management (SSPM). SSPM tools help monitor and manage misconfigurations, compliance gaps, and risks across your SaaS apps, giving you real-time visibility into your overall posture.
  2. Apply strong IAM policies. Go beyond MFA by implementing role-based access and regularly reviewing permissions to prevent over-privileged accounts.
  3. Add AI-Powered threat detection. AI and machine learning can help flag anomalies faster than humans, catching unusual behavior before it becomes a full-blown incident.
  4. Audit data sharing activity. Monitor how data is shared inside and outside your organization. Look for overly permissive sharing links or access granted to personal email accounts.
  5. Keep a usage inventory. Track which apps are in use, who’s using them, and whether they’re still needed. Get rid of redundant or risky tools to reduce your attack surface.
  6. Ensure data protections are in place. Know where your data is stored, how it’s encrypted, and whether your providers have strong controls in place. Ask hard questions and verify their answers.
  7. Monitor user access continuously. Implement real-time alerting for suspicious activity and adopt anomaly detection systems to flag behavior that deviates from the norm.
  8. Secure SaaS integrations. Third-party connections can be an overlooked risk. Audit integrations, enforce least-privilege access, and use SSO or SAML where possible.
  9. Add app discovery. Uncover unauthorized tools and shadow IT before they become a problem. Continuous discovery helps you stay ahead of unmanaged risk.

How to create an effective SaaS security checklist

The right SaaS security checklist for each organization is dependent on the specific circumstances of the business and the types of SaaS applications it uses. While every organization is unique, there are key components that every successful SaaS security plan should include.

‍

Here’s a sample checklist to get you started:

  • Proactive SaaS Discovery and Risk Assessment: Continuously monitor and evaluate all SaaS applications in use across your organization. Identifying potential vulnerabilities early on is crucial to minimizing risks. This helps organizations identify potential security vulnerabilities or compliance issues quickly.
  • Multi-Factor Authentication (MFA): Require MFA for all users to reduce the risk of unauthorized access and boost overall security.
  • Single Sign-On (SSO) Integration: Simplify access management by implementing SSO, which allows users to securely access multiple apps with just one set of credentials.
  • Shared Account Monitoring: Keep a close eye on accounts shared by multiple users to ensure that only authorized personnel are able to access sensitive data or make changes within the application.
  • Dormant Account Cleanup: Regularly review and deactivate dormant accounts—especially those of former employees—to eliminate potential security gaps. Forgotten dormant accounts can be especially vulnerable to malicious activity if left active without proper oversight.‍
  • Password Policy Enforcement: Implement strict password policies that follow NIST’s most recent Password Guidelines to defend against brute-force attacks.

‍

What is SaaS security posture management?

SaaS security posture management is the practice of overseeing and optimizing the security measures that protect your SaaS applications. It involves a comprehensive approach, with the goal of making sure that all SaaS tools and protocols work together to protect your organization from threats.

‍

SaaS security posture refers to the strength of an organization’s SaaS security measures, including the SaaS security tools and protocols that are in place to prevent and protect against threats introduced via SaaS application usage.

‍

SaaS security posture management refers to the effectiveness of the measures an organization uses to oversee and control the SaaS security tools and protocols that are in place.

‍

To manage your SaaS security posture effectively, start with a clear security policy that sets expectations for employees and establishes guidelines for secure SaaS usage. Your policy should cover everything from password protocols to incident response procedures, ensuring that all potential risks are addressed proactively.

‍

Organizations should also evaluate their existing SaaS solutions to identify any areas where additional security measures may be needed. For example, suppose sensitive data is stored in cloud storage solutions like Google Drive or Dropbox. In that case, organizations should ensure these services are configured with appropriate permissions to protect against unauthorized access or manipulation of data.

‍

Organizations should then work to implement additional protections, such as encryption or tokenization, depending on their specific requirements.

‍

Developing a SaaS security framework

A SaaS security framework is a set of guidelines and best practices that businesses can use to ensure the security of their SaaS applications. It is important for businesses that use many different SaaS applications to have an effective SaaS security framework in place, as it helps them protect their data, systems, and networks from potential threats.

‍

A modern SaaS security framework should include a comprehensive set of security best practices, a security policy template, and various SaaS security controls and tools.

‍

How to strengthen your SaaS security framework

A strong SaaS security framework is essential for any organization that uses multiple SaaS applications. This framework should include best practices for access control, user authentication, and data protection. Additionally, it should come with a detailed security policy template that outlines the steps employees must follow to keep SaaS use secure.

‍

Once you’ve got the policies in place, it’s time to implement technical controls such as firewalls, antivirus software, and intrusion detection systems. Monitoring tools like vulnerability scanners can further help you detect suspicious activity and respond quickly.

‍

Training is another key element of your framework. Regular sessions on SaaS security practices will go a long way in getting your employees to understand the importance of following security protocols and can act as the first line of defense against potential threats. Like any security awareness training, the sessions should be frequent, engaging, and empowering.

‍

Taking all these steps into consideration, you can ensure you are properly protecting sensitive data, upholding safety and privacy standards, and still allowing employees to make full use of all available SaaS resources.
