Many organizations operate a diverse range of applications, spanning various generations. These applications differ in age, ranging from recently developed ones to those that have been in use for several decades. Some have been procured from external suppliers, while others have been internally developed. 

These applications rely on a variety of underlying technologies, including databases and middleware. Over the past decade, organizations have increasingly shifted the responsibility of running and day-to-day management of their applications to hosting providers. More recently, they have extended this outsourcing to cloud service providers.

In this blog post, we will explore the advantages of opting for well-established Software as a Service (SaaS) applications when they are available. With this approach, cloud service providers take on the majority of the DevOps tasks, including security management and compliance with various international frameworks. 

Naturally, the organization will still retain many of its existing applications. This hybrid approach reduces the burden of IT management and mitigates associated risks.

Furthermore, organizations often need to adhere to standards such as ISO 20001, PCIDSS, and FedRAMP, necessitating the continuous collection of audit evidence.
Within an on-premise environment, the breadth and complexity of these security controls and compliance requirements can be daunting for many businesses to implement and maintain in a scalable and reliable manner.

What does handling internal security include

Handling the internal security of on-premise applications presents a significant challenge. Managing security requires a broad and deep expertise, encompassing a wide array of security controls that must be deployed and constantly monitored to ensure their proper functioning.

These controls include:

  • Network security configuration: Network security configuration is the process of setting up and maintaining a secure network infrastructure. This includes tasks such as configuring firewalls, intrusion detection/prevention systems (IDS/IPS), and virtual private networks (VPNs). The goal of network security configuration is to protect the network from unauthorized access, data breaches, and other security threats.
  • User authentication: User authentication is the process of verifying the identity of a user before granting them access to a system or resource. This is typically done by requiring the user to enter a username and password. Strong authentication methods, such as two-factor authentication, can help to prevent unauthorized access.
  • Entitlement management based on the principle of least privilege: Entitlement management is the process of assigning users the permissions they need to do their jobs. The principle of least privilege states that users should only be given the permissions they need to do their jobs, and no more. This helps to prevent unauthorized access to sensitive data and systems.
  • Management of privileged users: Privileged users are users who have been granted elevated permissions, such as the ability to install software or make changes to system configurations. Privileged users are a major security risk, as they can use their permissions to compromise a system. It is important to carefully manage privileged user accounts and to only grant them the permissions they need.
  • Malware detection: Malware is software that is designed to harm a computer system. Malware can be used to steal data, install other malware, or disrupt computer operations. Malware detection is the process of identifying and removing malware from a system. There are a number of different malware detection tools available, including antivirus software and anti-malware sandboxes.
  • Endpoint protection: Endpoint protection is the process of protecting endpoints, such as laptops and desktops, from security threats. This includes tasks such as installing antivirus software, configuring firewalls, and patching vulnerabilities. Endpoint protection is important because endpoints are often the target of malware attacks.
  • Intrusion detection and prevention: Intrusion detection (IDS) and intrusion prevention (IPS) systems are used to detect and prevent unauthorized access to a network or system. IDS systems monitor network traffic for suspicious activity, and IPS systems can block suspicious traffic.
  • Security event logging and analysis: Security event logging is the process of recording security-related events, such as login attempts and file access. Security event analysis is the process of analyzing security event logs to identify security threats. Security event logging and analysis can help to identify and respond to security incidents.
  • Incident detection and response: Incident detection is the process of identifying security incidents. Incident response is the process of responding to security incidents. Incident detection and response is an important part of any security program.
  • Business continuity management and disaster recovery: Business continuity management (BCM) is the process of ensuring that a business can continue to operate in the event of a disaster. Disaster recovery (DR) is the process of restoring a business to normal operations after a disaster. BCM and DR are important for any business that wants to protect itself from the financial impact of a disaster.

Understanding the need for SaaS security

Understanding the need for SaaS security

Numerous Software as a Service (SaaS) providers offer a comprehensive package of hosting, SaaS solutions, security, and maintenance services to their users. SaaS security, at its core, encompasses cloud-based measures designed to safeguard all software and data within the service. It involves a set of best practices that organizations, which store their data in the cloud, employ to fortify the protection of their information. 

While the SaaS provider shoulders the primary responsibility for securing the platform, network, applications, operating system, and the entire infrastructure, both the customer and the service provider share equal obligations. 

They are mandated to adhere to the SaaS security directives outlined by organizations like the National Cyber Security Center (NCSC) in the UK.

Given the wealth of sensitive data they contain, SaaS environments often become prime targets for cybercriminals. A security breach can compromise data safety and integrity, potentially resulting in substantial financial losses. The repercussions of such breaches are well-documented and severe, leaving no room for underestimation. 

Any successful intrusion into a SaaS environment can lead to catastrophic consequences.

Therefore, if SaaS vendors fail to consistently deliver top-notch services, service disruptions and security breaches may become recurring issues. Consequently, before engaging with any SaaS service, one must thoroughly review the Service Level Agreement (SLA) and pose pertinent questions to the provider.

Businesses must prioritize the implementation of best practices to avoid failure, not to mention the legal ramifications that could ensue. In essence, organizations utilizing the SaaS model must place a strong emphasis on SaaS security. 

This entails not only the practical aspects of securing the environment but also ensuring the necessary certifications are in place.

What are the SaaS security challenges in 2023

In 2023, the landscape of SaaS security is evolving, driven by increasingly sophisticated cyber threats and a growing reliance on cloud-based applications. 

Here are some of the primary challenges that organizations are currently grappling with:

  • Insufficient Authentication and Authorization: Weak authentication methods and improper authorization procedures can grant unauthorized users access to SaaS applications, putting sensitive data in jeopardy. Robust implementation of multi-factor authentication (MFA) and enforcement of least privilege access controls are essential to thwart unauthorized access.
  • Data Loss and Leakage: Data breaches and accidental data deletion continue to pose significant risks in SaaS environments. To mitigate these threats, organizations should adopt data loss prevention (DLP) solutions, encrypt sensitive data, and educate employees on data security best practices.
  • Vulnerable Third-party Integrations: Third-party integrations can introduce security vulnerabilities when not properly assessed and managed. Organizations must rigorously evaluate the security posture of third-party vendors and establish access controls and monitoring mechanisms for these integrations.
  • Insecure APIs: APIs are fundamental to SaaS applications, and vulnerabilities in APIs can serve as backdoors to sensitive data for attackers. Robust API security practices, including proper authentication, authorization, and input validation, are essential.
  • Shadow IT: The usage of unauthorized SaaS applications, commonly referred to as "shadow IT," can create security blind spots and expose organizations to unnecessary risks. Implementing policies and tools to identify and manage shadow IT usage is crucial.
  • Lack of Visibility and Control: Many organizations struggle with limited visibility into their SaaS usage, making it challenging to identify and manage security risks. To address this, deploying cloud access security brokers (CASBs) and cloud security posture management (CSPM) tools can offer greater control and insight into SaaS environments.
  • Regulatory Compliance: Navigating the intricate landscape of data privacy regulations and compliance requirements can be a daunting task for organizations using SaaS applications. Understanding and adhering to applicable regulations is vital to mitigate legal and reputational risks.
  • Training and Awareness: Employees often represent the weakest link in cybersecurity due to their lack of awareness and training. Thus, organizations should provide regular security awareness training to employees and foster a culture of cybersecurity.
  • Continuous Monitoring: SaaS environments are in a constant state of evolution, with new security threats continually emerging. Consequently, organizations must implement continuous monitoring and threat detection capabilities to promptly identify and respond to security incidents.
  • Managed Security Services: Many organizations may lack the internal resources and expertise required to effectively manage SaaS security. Engaging managed security service providers (MSSPs) can serve as a valuable complement to in-house capabilities.

What are the 4 SaaS best practices

Transitioning your systems and processes to SaaS can be a beneficial step. However, it's crucial to carefully assess your organization's current needs and the specific security demands of SaaS before proceeding.

To facilitate this transition, here are some recommended best practices for cloud security:

1.Build multi-tenant applications

Multi-tenant architecture enables the efficient sharing of computing resources among multiple customers, optimizing resource utilization and reducing instances of resource underutilization when compared to a single-tenant setup.

There are two primary methods for implementing a multi-tenant architecture:

  • Single Application Instance with Multiple Databases: This approach allows all users to access distinct databases concurrently, preventing any single database from becoming overwhelmed. It offers improved scalability, more resources for concurrent users, and a more responsive application. However, it necessitates a substantial initial investment due to the requirement for additional resources.
  • Single Application Instance with One Database: In this approach, all users access the same database until it reaches its capacity, at which point they are directed to a new database. While this approach is faster and more cost-effective to deploy, it may limit scalability, potentially impacting application performance and the user experience.

If your user base includes individuals with resource-intensive workloads that disproportionately consume resources, it may be necessary to consider a single-tenant approach. Such users could potentially degrade the user experience of other tenants in a multi-tenant environment.

2. Scalability as a part of your SaaS architecture from the start

 As your SaaS application gains traction and experiences growth in user demand, the ability to scale becomes paramount. A thriving business naturally generates a greater volume of transactions, queries, and metadata.

To address this, it's imperative to design your SaaS architecture in a way that allows for effortless scalability, ensuring it can adapt to the growing workload without sacrificing performance. 
This can be accomplished by ensuring that your SaaS architecture supports both horizontal and vertical scaling seamlessly.

  • Horizontal scaling: involves adding more instances or resources to distribute the increasing load across a greater number of servers or virtual machines. Amazon Web Services (AWS) offers services like Amazon EC2 Auto Scaling, which automatically adjusts the number of instances to handle changes in demand.
  • Vertical scaling: entails increasing the capacity of individual resources, such as upgrading a server's CPU, memory, or storage. AWS provides options to vertically scale instances when needed, like Amazon EC2 instances that can be resized to meet higher performance requirements.

By leveraging AWS services and infrastructure, your SaaS application can effectively and efficiently scale to meet the demands of your growing user base and workload, ensuring a seamless and high-performing experience.

3.Cost monitoring into your SaaS applications 

Cost monitoring for SaaS (Software as a Service) applications is crucial to ensure that you are managing your expenses effectively and optimizing your spending. 

Here are some best practices and ways to implement cost monitoring into your SaaS applications:

  • Identify Key Metrics: Start by identifying the key cost-related metrics you want to monitor, such as subscription fees, usage charges, and any additional costs like data storage or user licenses. Clearly define what you consider to be your baseline costs.
  • Budgeting: Establish a budget for your SaaS expenses. This budget should be based on your projected usage and the costs associated with your SaaS subscriptions. Regularly review and adjust this budget as your needs change.
  • Centralized Dashboard: Create a centralized dashboard or use SaaS management tools that provide a consolidated view of your SaaS expenses. This dashboard should display real-time data on costs and usage for each application.
  • Categorize Expenses: Categorize your SaaS expenses by application, department, or usage type. This helps you understand which teams or functions are responsible for different costs and can aid in allocation and optimization.
  • Automated Alerts: Set up automated alerts for cost thresholds. When your SaaS spending approaches or exceeds predefined limits, you and relevant team members should receive notifications. This allows for proactive cost management.
  • Usage Analysis: Analyze the usage patterns of your SaaS applications. Determine whether you are paying for unused licenses or if you can optimize usage by adjusting the number of licenses or the subscription plan.
  • Contract Reviews: Regularly review your SaaS contracts and subscription plans. Ensure that you are not overpaying for features or capacity that you do not need. Negotiate with vendors when necessary to get the best rates.
  • Rightsizing: Optimize your SaaS subscriptions by "rightsizing." If you find that your actual usage is significantly lower than what you're paying for, consider downgrading your subscription to a more cost-effective plan.
  • User Access Control: Manage user access and permissions. Revoke access for users who no longer require it, reducing unnecessary costs. Implement role-based access control to avoid over-provisioning.
  • Data Archiving and Cleanup: If your SaaS applications involve data storage, regularly clean up and archive data that is no longer needed. This can help reduce storage costs.
  • Benchmarking: Compare your SaaS costs to industry benchmarks to see if you are spending more than you should be. This can highlight areas where you might need to cut costs.
  • Cost Allocation: Implement cost allocation practices to distribute SaaS expenses accurately across different departments or cost centers. This helps with accountability and can lead to better decision-making.
  • Regular Reviews: Schedule regular reviews of your SaaS expenses and usage. This could be monthly, quarterly, or annually, depending on your organization's needs. Use these reviews to make informed decisions about your SaaS portfolio.
  • Training and Awareness: Educate your team members about the cost implications of their SaaS usage. Encourage them to be mindful of their actions, such as not installing unnecessary applications or choosing expensive features.
  • Third-Party Tools: Consider using third-party SaaS management and cost optimization tools that can automate many of these monitoring and management tasks.

By implementing these best practices, you can effectively monitor and manage the costs of your SaaS applications, ensuring that you are getting value for your investment and avoiding unnecessary expenses.

4.Focus on data security in mind 

Many organizations prefer a monolithic or on-premises architecture due to perceived data security benefits. However, with heightened cybersecurity concerns and the rising costs of data breaches, organizations are increasingly investing in robust cybersecurity measures.

Implementing Role-Based Access Control (RBAC) as a fundamental component of your SaaS architecture can significantly enhance data security. RBAC is a data access control mechanism that restricts user access to data directly relevant to their job responsibilities.

RBAC allows for the designation of administrators, vendors, end-users, contractors, and other user types. Roles can be assigned based on job competency or authorization levels.

SaaS security benefits?

Enhanced authentication is a critical component of SaaS security best practices. It involves strengthening the process of verifying the identity of users accessing SaaS applications. This approach goes beyond basic username and password combinations to provide an additional layer of security. Here are some of the benefits of enhanced authentication in the context of SaaS security:

  • Improved Security: Enhanced authentication methods, such as multi-factor authentication (MFA) or biometric authentication, significantly enhance security by requiring users to provide multiple forms of verification. This makes it much more difficult for unauthorized users to gain access to sensitive data and systems.
  • Reduced Risk of Unauthorized Access: Enhanced authentication helps mitigate the risk of unauthorized access to SaaS applications. Even if a user's password is compromised, additional authentication factors like a fingerprint, token, or SMS code are still required to gain access.
  • Protection of Sensitive Data: SaaS applications often store sensitive and confidential data. Enhanced authentication helps protect this data by ensuring that only authorized users can access it, reducing the risk of data breaches and leaks.
  • Compliance with Regulations: Many industries and regions have strict regulatory requirements for data security and privacy. Implementing enhanced authentication can help organizations comply with these regulations, reducing the risk of fines and legal consequences.
  • User-Friendly Experience: While security is paramount, enhanced authentication can also improve the user experience. It allows for flexibility in choosing authentication methods, such as using a fingerprint scanner on a mobile device, making it more convenient for users.
  • Adaptability: Enhanced authentication can be tailored to fit the specific needs of an organization. Depending on the level of security required for different users or applications, you can implement various authentication methods, ensuring that resources are adequately protected.
  • Mitigation of Phishing and Credential Theft: Phishing attacks and credential theft are common methods used by cybercriminals. Enhanced authentication makes it much more challenging for attackers to use stolen credentials since they would also need access to the second authentication factor.
  • Remote Work Enablement: With the rise of remote work, securing access to SaaS applications from various locations and devices is crucial. Enhanced authentication ensures that remote users can access resources securely, even outside the traditional office environment.
  • Cost Savings: While there may be an initial cost associated with implementing enhanced authentication, the long-term benefits in terms of reduced security incidents and potential data breaches can lead to cost savings by preventing costly incidents and their associated expenses.

In conclusion, enhanced authentication is a fundamental component of SaaS security best practices. It offers a robust defense against unauthorized access and helps protect sensitive data, making it an essential measure for any organization relying on SaaS applications to safeguard their digital assets and maintain compliance with security regulations.

Wrapping up 

The advantages of SaaS security are numerous and can shield a company from severe repercussions in the wake of cyber-attacks and data breaches. 

This is why any business that depends on SaaS applications should implement suitable security measures to safeguard their data, assets, and reputation.

With the assistance of SaaS management and automated tools, the enforcement of SaaS security best practices is not overly complex and can be achieved by adhering to well-established techniques. 

Nevertheless, it is crucial to remember that once these security measures are in place, they require consistent monitoring and updates, akin to each individual SaaS application.
