The most effective way to avoid paying the ransom in a ransomware attack is to have a properly tested offline backup system. A ransomware attack is a type of cyberattack that encrypts the victim’s data or systems and demands a payment for the decryption key. A properly tested offline backup system is a method of storing copies of the data or systems in a separate location that is not connected to the network or the internet. By having a properly tested offline backup system, the hospital can restore its critical server from the backup without paying the ransom or losing any data. The other options are not the most effective way to avoid paying the ransom in a ransomware attack, although they may be some preventive or detective measures. Employee training on ransomware is a preventive measure that can help raise awareness and reduce the likelihood of falling victim to phishing or other social engineering techniques that may deliver ransomware. However, it does not guarantee that employees will always follow best practices or that ransomware will not enter the network through other means. A continual server replication process is a method of creating copies of the server data or systems in real time or near real time. However, it may not be effective against ransomware, as the replication process may also copy the encrypted data or systems, making them unusable. A properly configured firewall is a preventive measure that can help block malicious network traffic and prevent unauthorized access to the server. However, it does not guarantee that ransomware will not bypass the firewall through other channels, such as email attachments or removable media.

 Information security controls should be designed primarily based on business risk scenarios, because they help to identify and prioritize the most relevant and significant threats and vulnerabilities that may affect the organization’s information assets and business objectives. Business risk scenarios are hypothetical situations that describe the possible sources, events, and consequences of a security breach, as well as the likelihood and impact of the occurrence. Business risk scenarios can help to:

Align the information security controls with the business needs and requirements, and ensure that they support the achievement of the strategic goals and the mission and vision of the organization

Assess the effectiveness and efficiency of the existing information security controls, and identify the gaps and weaknesses that need to be addressed or improved

Select and implement the appropriate information security controls that can prevent, detect, or mitigate the risks, and that can provide the optimal level of protection and performance for the information assets

Evaluate and measure the return on investment and the value proposition of the information security controls, and communicate and justify the rationale and benefits of the controls to the stakeholders and management

Information security controls should not be designed primarily based on a business impact analysis (BIA), regulatory requirements, or a vulnerability assessment, because these are secondary or complementary factors that influence the design of the controls, but they do not provide the main basis or criteria for the design. A BIA is a method of estimating and comparing the potential effects of a disruption or a disaster on the critical business functions and processes, in terms of financial, operational, and reputational aspects. A BIA can help to determine the recovery objectives and priorities for the information assets, but it does not identify or address the specific risks and threats that may cause the disruption or the disaster. Regulatory requirements are the legal, contractual, or industry standards and obligations that the organization must comply with regarding information security. Regulatory requirements can help to establish the minimum or baseline level of information security controls that the organization must implement, but they do not reflect the specific or unique needs and challenges of the organization. A vulnerability assessment is a method of identifying and analyzing the weaknesses and flaws in the information systems and assets that may expose them to exploitation or compromise. A vulnerability assessment can help to discover and remediate the existing or potential security issues, but it does not consider the business context or impact of the issues.

Business strategy is the overarching driver for any organizational initiative, including security. Information security policies must align with the strategic goals of the organization to ensure relevance, support, and effectiveness.

Security policies that do not consider the business context may hinder operations or fail to protect key objectives. Business-driven policies are more likely to gain executive support and compliance from stakeholders, creating a strong foundation for governance.

“Information security policies must be aligned with business goals and objectives to ensure that they support the overall mission and are embraced by stakeholders.”

Establishing risk metrics best enables an organization to increase information security control effectiveness because metrics provide measurable insight into whether controls are reducing risk as intended. CISM emphasizes that control effectiveness must be monitored using meaningful measurements aligned with risk appetite, business objectives, and key risk indicators. Reviewing implementation progress only confirms whether controls are being deployed; it does not prove that controls are effective. Performing periodic criticality analysis may help prioritize controls, but it does not continuously measure performance. Reassigning ownership may be appropriate when accountability problems exist, but it is reactive and limited to failing areas. Risk metrics enable management to detect control weaknesses, track trends, prioritize improvements, and make informed decisions. They also support continuous improvement by showing whether residual risk is moving toward acceptable levels. Therefore, risk metrics are the best mechanism to increase effectiveness because they connect control performance directly to risk reduction and management objectives.

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.

Ensuring the business can operate is the primary consideration when responding to a ransomware attack because it helps to minimize the disruption and impact of the attack on the organization’s mission-critical functions and services. Ransomware is a type of malware that encrypts the files or systems of the victims and demands payment for their decryption. Ransomware attacks can cause significant operational, financial, and reputational damage to organizations, especially if they affect their core business processes or customer data. Therefore, ensuring the business can operate is the primary consideration when responding to a ransomware attack.

= The information security manager’s first course of action in this situation should be to conduct a risk assessment, which is a process of identifying, analyzing, and evaluating the information security risks that arise from the violation of the policy prohibiting the use of cameras at the office. The risk assessment can help to determine the likelihood and impact of the unauthorized or inappropriate use of the cameras on the smartphones and tablet computers, such as capturing, transmitting, or disclosing sensitive or confidential information, compromising the privacy or security of the employees, customers, or partners, or violating the legal or regulatory requirements. The risk assessment can also help to identify and prioritize the appropriate risk treatment options, such as implementing technical, administrative, or physical controls to disable, restrict, or monitor the camera usage, enforcing the policy compliance and awareness, or revising the policy to reflect the current business needs and environment. The risk assessment can also help to communicate and report the risk level and status to the senior management and the relevant stakeholders, and to provide feedback and recommendations for improvement and optimization of the policy and the risk management process.

Revising the policy, performing a root cause analysis, and communicating the acceptable use policy are all possible courses of action that the information security manager can take after conducting the risk assessment, but they are not the first ones. Revising the policy is a process of updating and modifying the policy to align with the business objectives and strategy, to address the changes and challenges in the business and threat environment, and to incorporate the feedback and suggestions from the risk assessment and the stakeholders. Performing a root cause analysis is a process of investigating and identifying the underlying causes and factors that led to the violation of the policy, such as the lack of awareness, training, or enforcement, the inconsistency or ambiguity of the policy, or the conflict or gap between the policy and the business requirements or expectations. Communicating the acceptable use policy is a process of informing and educating the employees and the other users of the smartphones and tablet computers about the purpose, scope, and content of the policy, the roles and responsibilities of the users, the benefits and consequences of complying or violating the policy, and the methods and channels of reporting or resolving any policy issues or incidents. References = CISM Review Manual 15th Edition, pages 51-531; CISM Practice Quiz, question 1482
