Defining information security requirements and processes is the FIRST thing that the information security manager should do to support the initiative of utilizing Software as a Service (SaaS) and selecting a vendor. This is because information security requirements and processes provide the basis for evaluating and comparing the SaaS vendors and solutions, as well as for ensuring the alignment of the SaaS services with the organization’s security objectives, policies, and standards. Information security requirements and processes should include aspects such as data protection, access control, encryption, authentication, authorization, audit, compliance, incident response, disaster recovery, and service level agreements12. Reviewing independent security assessment reports for each vendor (A) is a useful thing to do to support the initiative of utilizing SaaS and selecting a vendor, but it is not the FIRST thing to do. Independent security assessment reports can provide valuable information about the security posture, practices, and performance of the SaaS vendors and solutions, such as their compliance with industry standards, frameworks, and regulations, their vulnerability and risk management, and their security testing and auditing results. However, reviewing independent security assessment reports should be done after defining the information security requirements and processes, which can help to determine the scope, criteria, and expectations for the security assessment12. Benchmarking each vendor’s services with industry best practices (B) is also a useful thing to do to support the initiative of utilizing SaaS and selecting a vendor, but it is not the FIRST thing to do. Benchmarking each vendor’s services with industry best practices can help to measure and compare the quality, performance, and value of the SaaS vendors and solutions, as well as to identify the gaps, strengths, and weaknesses of the SaaS services. However, benchmarking each vendor’s services with industry best practices should be done after defining the information security requirements and processes, which can help to select the relevant and appropriate industry best practices for the SaaS services12. Analyzing the risks and proposing mitigating controls © is also a useful thing to do to support the initiative of utilizing SaaS and selecting a vendor, but it is not the FIRST thing to do. Analyzing the risks and proposing mitigating controls can help to identify and evaluate the potential threats, vulnerabilities, and impacts that may affect the security, availability, and reliability of the SaaS vendors and solutions, as well as to recommend and implement the necessary measures to reduce or eliminate the risks. However, analyzing the risks and proposing mitigating controls should be done after defining the information security requirements and processes, which can help to establish the risk appetite, tolerance, and criteria for the SaaS services12.
