Empower Your Business with Secure SaaS: Best Practices For Enhanced Security
Applications that provide Software-as-a-Service (SaaS) have become important to many enterprises in today's digital environment. They offer a plethora of advantages, including scalability, affordability, and ease of use. However, the very nature of cloud-based solutions introduces inherent security concerns. That is why, in this article, we discuss SaaS security best practices, empowering you to leverage the benefits of SaaS while minimizing risks.
How to Make SaaS More Secure? A Multi-Layered Approach
Building a secure SaaS environment requires a collaborative effort from both the SaaS provider and the user organization. Therefore, the following is a complete breakdown of what security measures to look for in a SaaS company that fosters a holistic approach:
Secure Infrastructure & Data Centers
Physical Security: The provider should have robust physical security measures in place for their data centers, including access control systems, surveillance cameras, and environmental controls to prevent unauthorized access and mitigate physical threats like fire or flooding.
Network Security: The provider's network infrastructure should be secure, utilizing firewalls, intrusion detection and prevention systems (IDS/IPS), as well as data encryption protocols to safeguard data in transit between users and servers.
Secure Application Development
Secure Coding Practices: Developers should adhere to secure coding practices to minimize vulnerabilities within the SaaS application. This includes using well-established coding libraries, regularly conducting code reviews, and implementing automated vulnerability scanning tools.

Bug bounty programs can also be valuable, incentivizing security researchers to discover and report vulnerabilities.
Strong Identity & Access Management (IAM)
Multi-Factor Authentication (MFA): All user accounts should be subject to MFA enforcement by the provider. MFA requires a second factor in addition to a password when logging in. This can include one-time codes given by SMS or authenticator applications, security tokens, and fingerprint scanners.
Single Sign-On (SSO): By enabling users to authenticate for several SaaS apps using a single set of credentials, SSO may simplify user access. This enhances general security and lowers the possibility of password fatigue.
User Activity Monitoring: The provider should monitor user activity within the SaaS application to detect suspicious behavior. This can help identify unauthorized access attempts, data exfiltration attempts, or potential insider threats.
Robust Data Security Measures
Data Encryption: Data requires encryption when in the provider's servers and transit between users and the SaaS platform. Additionally, industry-standard encryption algorithms like AES-256 can render data unreadable in case of a security breach.
Data Loss Prevention (DLP): The supplier should have DLP capabilities to prevent sensitive data from being unintentionally or purposely released outside the company. DLP rules can restrict unauthorized data transfers via email, file-sharing platforms, or USB drives.
Data Residency: For certain data types with regulatory compliance requirements, consider choosing a SaaS provider that stores data within a specific geographic region to comply with data residency laws.
Transparency and Communication
Security Certifications: Seek suppliers with industry-accredited security certifications such as SOC 2, ISO 27001, or PCI DSS. These accreditations show how dedicated the supplier is to using strong security procedures.
Security Incident Response: The provider should have an incident response strategy that details what to do in the event of a security breach. This plan should be transparently communicated to users, outlining communication protocols and recovery procedures.
Regular Security Updates: The provider should be proactive in patching vulnerabilities within the SaaS application. Look for providers with a well-defined patch management process and clear communication regarding security updates.
All in all, by implementing these multi-layered security measures, both SaaS providers and user organizations can create a more secure environment for cloud-based applications. However, it's crucial to remember that security is a shared responsibility, requiring ongoing collaboration and a commitment to continuous improvement.
Building a SaaS Security Checklist: Internal Safeguards
Once you've chosen a secure SaaS provider, the onus falls on your organization to implement internal security measures. The SaaS security checklist should include the following:
Strong Authentication & Access Control (IAM): To increase protection beyond passwords, all user accounts should be subject to multi-factor authentication (MFA). Granular access restrictions should also be implemented to guarantee that users only have access to the information and features necessary for their job functions.
Regular User Activity Monitoring: Monitor user activity within the SaaS application to identify suspicious behavior. Look for anomalies like unusual login times, access attempts from unfamiliar locations, or excessive data downloads.
Data Loss Prevention (DLP): Implement DLP solutions to prevent sensitive data from being accidentally or intentionally leaked outside the organization. Furthermore, configure DLP rules to restrict unauthorized data transfers via email, file-sharing platforms, or USB drives.
SaaS Security Awareness Training: Train your employees on best practices for secure SaaS usage. Additionally, educate them on phishing scams, social engineering tactics, and password hygiene practices.
