Management decisions concerning information security investments will be most effective when they are based on the reporting of consistent and periodic assessments of risks. This will help management to understand the current and emerging threats, vulnerabilities, and impacts that affect the organization’s information assets and business processes. It will also help management to prioritize the allocation of resources and funding for the most critical and cost-effective security controls and solutions. The reporting of consistent and periodic assessments of risks will also enable management to monitor the performance and effectiveness of the information security program, and to adjust the security strategy and objectives as needed. References = CISM Review Manual 15th Edition, page 28.

Email software packages that provide native encryption of messages use proprietary algorithms and formats that are not compatible with other email software packages. This means that the encryption cannot interoperate across product domains, and the recipients of encrypted messages must use the same email software package as the sender to decrypt and read the messages. This limits the usability and scalability of native encryption, and may also pose security risks if the encryption algorithms or formats are not well-tested or widely accepted. A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains1234. References = CISM Review Manual 15th Edition, page 206. The Top 10 Email Encryption Solutions In 2023 - Expert Insights2, The Best Email Encryption Services for 2023 | PCMag3, The Top 12 Email Encryption Services for 2023 - Right Inbox4.

A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains. This means that emails sent from one product cannot be read by another product, as the encryption keys used are not compatible. This can be a problem when sending emails to people who use different software packages, as the encrypted emails cannot be read.

 = Penetration testing is most appropriate when a new system is about to go live, because it is a method of evaluating the security of a system by simulating an attack from a malicious source. Penetration testing can help to identify and exploit vulnerabilities, assess the impact and risk of a breach, and provide recommendations for remediation and improvement. Penetration testing can also help to validate the effectiveness of the security controls and policies implemented for the new system, and ensure compliance with relevant standards and regulations. Penetration testing is usually performed after the system has undergone other types of testing, such as functional, performance, and usability testing, and before the system is deployed to the production environment. Penetration testing is not as appropriate when a new system is being designed, because the system is still in the early stages of development and may not have all the features and functionalities implemented. Penetration testing at this stage may not provide a realistic or comprehensive assessment of the system’s security, and may cause delays or disruptions in the development process. Penetration testing is also not as appropriate when a security policy is being developed, because the policy is a high-level document that defines the goals, objectives, and principles of information security for the organization. Penetration testing is a technical and operational activity that tests the implementation and enforcement of the policy, not the policy itself. Penetration testing is also not as appropriate when a security incident has occurred, because the incident may have already compromised the system and caused damage or loss. Penetration testing at this stage may not be able to prevent or mitigate the incident, and may interfere with the incident response and recovery efforts. Penetration testing after an incident may be useful for forensic analysis and lessons learned, but it is not the primary or immediate response to an incident. References = CISM Review Manual, 16th Edition, ISACA, 2021, pages 229-230, 233-234.
