= After a ransomware incident, the most important concern for the information security manager is to identify the root cause of the incident and prevent it from happening again. The root cause analysis (RCA) is a systematic process of finding and eliminating the underlying factors that led to the incident, such as vulnerabilities, misconfigurations, human errors, or malicious actions. Without performing a RCA, the organization may not be able to address the root cause and may face the same or similar incidents in the future, which could result in more damage, costs, and reputational loss. Therefore, the information security manager should prioritize the RCA over other concerns, such as meeting the SLA, RTO, or notification requirements, which are important but secondary to the RCA.

Proactive monitoring (e.g., threat hunting, real-time log analysis, anomaly detection) is the most effective defense against Advanced Persistent Threats (APTs), which are stealthy, well-resourced, and long-term attacks.

APT actors:

Use zero-day exploits

Maintain long-term unauthorized access

Avoid detection

Traditional controls often fail. Proactive monitoring detects anomalies early, allowing for faster mitigation.

“Ongoing monitoring and detection programs are essential for identifying and responding to persistent and evolving threats.”

 = An identity and access management (IAM) system is a set of processes, policies, and technologies that enable an organization to manage the identities and access rights of its users across different systems and applications1. An IAM system can help an organization to comply with the government regulation by automating the provisioning and deprovisioning of user accounts, enforcing consistent access policies, and integrating different user directories2. An IAM system can also provide audit trails and reports to demonstrate compliance with the regulation3. A multi-factor authentication (MFA) system is a method of verifying the identity of a user by requiring two or more factors, such as something the user knows, has, or is4. An MFA system can enhance the security of user authentication, but it does not address the issue of removing user privileges from different systems within three days of termination. A privileged access management (PAM) system is a solution that manages and monitors the access of privileged users, such as administrators, to critical systems and resources. A PAM system can reduce the risk of unauthorized or malicious use of privileged accounts, but it does not solve the problem of managing the access of regular users across different systems. A governance, risk, and compliance (GRC) system is a software platform that integrates the functions of governance, risk management, and compliance management. A GRC system can help an organization to align its objectives, policies, and processes with the relevant regulations, standards, and best practices, but it does not directly enable the removal of user privileges from different systems within three days of termination. References = 1: CISM Review Manual (Digital Version), page 24 2: 1 3: 2 4: CISM Review Manual (Digital Version), page 25 : CISM Review Manual (Digital Version), page 26 : CISM Review Manual (Digital Version), page 27

Changes to the risk landscape are the most likely events to require an organization to revisit its information security framework, because they may affect the organization’s risk appetite, risk tolerance, risk profile, and risk treatment strategies. The information security framework should be aligned with the organization’s business objectives and risk management approach, and should be reviewed and updated regularly to reflect the changing internal and external environment.
