Today, most of the applications are being developed based on the SaaS (Software-as-a-Service) accessed via the cloud. Some apps like Google-Suite, Salesforce, and Basecamp have been developed to secure the data being transmitted by many people every day. Covid-19 has changed the world where work from home became a mandate, and thus SaaS applications’ demand increased. SaaS developers should make sure of security features to provide their customers with a trustworthy application.
What is SaaS?
Numerous definitions are there to describe SaaS. SaaS (Software-as-a-Service) is a cloud-based application with access to the application through internet browser rather than downloading it on your desktop or business networks to utilize and update. A software application can be office software or unified communication among other business apps available.
SaaS is not a buzzword, it’s a technology that came into existence bringing about change in the global digitalization trend and the software we use. Thus, the SaaS software developed where vendors can utilize the software remotely and deliver by subscribing through the internet. This software has many advantages like
- Can set up quickly with less loading speed
- Can update easily
- Enhanced flexibility
- Cost reduction
- Enhanced security
Best Practices for SaaS security?
Now, that we understood what SaaS is and why it is implemented, here are the best practices for SaaS security which developers need to remember.
A Detailed guide about SaaS security:
The guide should include your security strategies and how to formulate it? The method it has is listed below.
How to know and calculate the software environment and how to detect security vulnerabilities and risks? The guide will be useful to have the security knowledge framework by OWASP.
- The process to define and eliminate the risks.
- There will be a checklist of internal controls and security standards for SaaS applications. A suggestion here, don’t forget that SaaS security checklist needs to include a security-friendly culture.
- Should include an on-boarding and off-boarding checklist which describes security-related issues. For instance, they relate to the manager’s password utilization, computers, and employer’s necessary information.
- Should specify user management on how it controls the data flow in your application.
- Should include public and internal security policies and inform your users about how you collect the data and how you process it.
Create a secure and safe software development life cycle (SDLC): Develop secure SDLC which informs about security activities it implies throughout the development lifecycle. Make sure it consists of safe coding methodologies, vulnerability analyses, threat modelling, and penetration tests. This process helps to detect the SaaS security risks in each development so that problems can rectify before production.
Ensure your users have secure deployment:
SaaS security guide should also include the concerns of deployment safety. Here, two main options are available for security deployment.
- Cloud deployment: Developers should give assurance for the SaaS data security, data segregation, and infrastructure hardening.
- Self-hosted deployment: Users should pay attention to prevent DoS (denial-of-service) and network penetration attacks. Best practices for users to solve the problem are continuous integration, delivery, and deployment. Also, users need to automate the deployment process for a long time.
Generate automated backups:
It’s essential to generate automated backups, and it is a crucial part of the SaaS security checklist because it is an unobtrusive safety measure. More time and efforts are not required if appropriately configured. There will be a data backup option to recover the system if any security attack occurs and if data gets destroyed or deleted.
Make sure to implement security controls:
Ensure SaaS application security controls to detect avoid and reduce security risks from different assets. Do you know what the security controls that the provider needs to implement are? Below is the SaaS security checklist.
- Data encryption and tokenization implementation
- Should implement malware prevention
- Data loss prevention
- Should detect proxy-based real-time
- Offline repository inspection
- Companies should identify and access the management like creating password policies, using two-factor authentication, enforcing access controls, and securing access management.
- Should include Logging controls
SaaS technology ensures cost reduction, agile performance in financial and regulatory departments in the banking industry. Implement this application to manage the customer sensitive information, regulatory compliance, and help other areas of the business. Choose the right technology and best practices for SaaS security can be more reliable and secure than on-premise applications. Banks have an advantage for retaining control over the security infrastructure like encrypting the customer data.
