CISM Exam Dumps - Certified Information Security Manager

 The best way to test for the existence of backdoors in a mission-critical business application that was outsourced to a third-party developer is to perform security code reviews on the entire application. A backdoor is a hidden or undocumented feature or function in a software application that allows unauthorized or remote access, control, or manipulation of the application or the system it runs on. Backdoors can be intentionally or unintentionally introduced by the developers, or maliciously inserted by the attackers, and they can pose serious security risks and threats to the organization and its data. Security code reviews are the process of examining and analyzing the source code of a software application to identify and eliminate any security vulnerabilities, flaws, or weaknesses, such as backdoors, that may compromise the functionality, performance, or integrity of the application or the system. Security code reviews can be performed manually by the security experts, or automatically by the security tools, or both, and they can be done at different stages of the software development life cycle, such as design, coding, testing, or deployment. Security code reviews can help to detect and remove any backdoors in the application before they can be exploited by the attackers, and they can also help to improve the quality, reliability, and security of the application.

The first course of action when the information security manager becomes aware that a third-party provider is not in compliance with the SOW is to assess the extent of the issue, which means determining the nature, scope, and impact of the non-compliance on the security of the enterprise’s data and systems. The assessment should also identify the root cause of the non-compliance and the possible remediation actions. The assessment will help the information security manager to decide the next steps, such as notifying senior management, reporting the issue to legal personnel, initiating contract renegotiation, or terminating the contract.

When security is embedded in organizational culture, it becomes a shared responsibility, increasing adherence and effectiveness.

“A security-aware culture is a key component of an effective security program because it encourages responsible behavior and supports ongoing risk management.”

— CISM Review Manual 15th Edition, Chapter 3: Information Security Program Development and Management, Section: Security Culture

ISACA’s practice questions identify security culture as the foundational element impacting the organization’s entire security posture.

The most important consideration when establishing information security policies for an organization is to ensure that senior management supports the policies. Senior management support is essential for the successful implementation and enforcement of information security policies, as it demonstrates the commitment and accountability of the organization’s leadership to information security. Senior management support also helps to allocate adequate resources, establish clear roles and responsibilities, and promote a security-aware culture within the organization. Without senior management support, information security policies may not be aligned with the organization’s goals and objectives, may not be communicated and disseminated effectively, and may not be followed or enforced consistently.

Job descriptions that include requirements to read security policies are a way of ensuring that employees are aware of their security obligations, but they are not the most important consideration when establishing information security policies. The policies should be relevant and applicable to the employees’ roles and functions, and should be reinforced by regular training and awareness programs.

The policies should be updated periodically to reflect the changes in the organization’s environment, risks, and requirements, but updating them annually may not be sufficient or necessary. The frequency of updating the policies should depend on the nature and impact of the changes, and should be determined by a defined policy review process.

The policies should be aligned with industry best practices, standards, and frameworks, but this is not the most important consideration when establishing information security policies. The policies should also be customized and tailored to the organization’s specific context, needs, and expectations, and should be consistent with the organization’s vision, mission, and values. References =
