CISM Exam Dumps - Certified Information Security Manager

Redirecting the attacker’s traffic is a viable containment strategy for a distributed denial of service (DDoS) attack because it helps to divert the malicious traffic away from the target server and reduce the impact of the attack. A DDoS attack is an attempt by attackers to overwhelm a server or a network with a large volume of requests or packets, preventing legitimate users from accessing the service or resource. Redirecting the attacker’s traffic is a technique that involves changing the DNS settings or routing tables to send the attacker’s traffic to another destination, such as a sinkhole, a honeypot, or a scrubbing center. A sinkhole is a server that absorbs and discards the malicious traffic. A honeypot is a decoy server that mimics the target server and collects information about the attacker’s behavior and techniques. A scrubbing center is a service that filters out the malicious traffic and forwards only the legitimate traffic to the target server. Redirecting the attacker’s traffic helps to contain the DDoS attack by reducing the load on the target server and preserving its availability and performance. Therefore, redirecting the attacker’s traffic is the correct answer.

The business data owner is accountable for data loss in the event of an information security incident at a third-party provider because they are ultimately responsible for the protection and use of their data, regardless of where it is stored or processed. The information security manager is not accountable for data loss at a third-party provider, but rather responsible for implementing and enforcing the security policies and standards that govern the relationship with the provider. The service provider that hosts the data is not accountable for data loss at their site, but rather liable for any breach of contract or service level agreement that may result from such an incident. The incident response team is not accountable for data loss at a third-party provider, but rather responsible for responding to and managing the incident according to the incident response plan.

The fundamental purpose of establishing security metrics is to provide feedback on the effectiveness of the information security controls and processes. Security metrics are quantitative or qualitative measures that indicate how well the organization is achieving its security objectives and goals. Security metrics can help the information security manager to monitor, evaluate, and improve the performance of the information security program, as well as to identify gaps, weaknesses, and areas for improvement. Security metrics can also help the organization to demonstrate compliance with internal and external standards, regulations, and best practices. Increasing return on investment (ROI), adopting security best practices, and establishing security benchmarks are possible outcomes or benefits of using security metrics, but they are not the fundamental purpose of establishing them. References = CISM Review Manual, 16th Edition, pages 46-471; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 642

Security metrics are used to measure the effectiveness of controls and evaluate the overall security posture of an organization. This feedback provides an understanding of the progress made towards achieving security objectives and allows organizations to make necessary adjustments.

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.

The greatest challenge with assessing emerging risk in an organization is the incomplete identification of threats, as emerging risks are often new, unknown, or unfamiliar, and may not be fully understood or assessed. Incomplete identification of threats can lead to gaps in risk analysis and management, and expose the organization to unexpected or unprepared scenarios. The other options, such as lack of a risk framework, ineffective security controls, or presence of known vulnerabilities, are not specific to emerging risks, and may apply to any type of risk assessment.

The most effective way to prevent information security incidents is to implement a security awareness training program for employees. Security awareness training provides employees with the knowledge and skills they need to identify potential security threats and protect their systems from unauthorized access and malicious activity. Security awareness training also helps to ensure that employees understand their roles and responsibilities when it comes to information security, and can help to reduce the risk of information security incidents by making employees more aware of potential risks. Additionally, implementing a security information and event management (SIEM) tool, deploying a consistent incident response approach, and deploying intrusion detection tools in the network environment can also help to reduce the risk of security incidents
