A disaster recovery plan (DRP) is a document that defines the procedures and resources needed to restore normal operations after a major disruption. A DRP typically includes the following elements:

• The scope and objectives of the plan
• The roles and responsibilities of the DR team
• The inventory and location of critical assets and resources
• The recovery strategies and procedures for different scenarios
• The testing and maintenance schedule for the plan
• The communication plan for internal and external stakeholders

One of the key components of a DRP is the recovery sequence, which is the optimal, sequential order in which cloud resources should be recovered in the event of a major failure. The recovery sequence is based on the priority and dependency of the resources, as well as the recovery time objective (RTO) and recovery point objective (RPO) of the business. The recovery sequence helps to minimize the downtime and data loss, and ensure the continuity of the business operations.

A recovery point objective (RPO) is the maximum acceptable amount of data loss measured in time. It indicates how often the data should be backed up and how much data can be restored after a disaster. A recovery time objective (RTO) is the maximum acceptable amount of time that a system or application can be offline after a disaster. It indicates how quickly the system or application should be restored and how much downtime can be tolerated by the business.

An incident response plan (IRP) is a document that defines the procedures and actions to be taken in response to a security breach or cyberattack. An IRP typically includes the following elements:

• The scope and objectives of the plan
• The roles and responsibilities of the incident response team
• The incident identification and classification criteria
• The incident containment, eradication, and recovery steps
• The incident analysis and reporting methods
• The incident prevention and improvement measures

A network topology diagram is a visual representation of the physical and logical layout of a network. It shows the devices, connections, and configurations of the network. A network topology diagram can help to identify the potential points of failure, the impact of a failure, and the recovery options for a network. However, it does not define the optimal, sequential order in which cloud resources should be recovered in the event of a major failure.

Audit and system logs are the best resource to use to start the investigation of an email phishing campaign against a company’s email server. Audit and system logs are records of events and activities that occur on a system or a network, such as user login, file access, configuration changes, or network traffic. Audit and system logs can help an incident response team to identify the source, scope, and impact of the phishing attack, as well as to collect evidence, trace the attack steps, and determine the root cause. Audit and system logs can also help the incident response team to evaluate the security posture and controls of the email server, and to recommend remediation and mitigation actions12

Multifactor authentication is a security method that requires users to provide more than one piece of evidence to verify their identity before accessing a cloud service. For example, users may need to enter a password, a code sent to their phone or email, a biometric scan, or a physical token. Multifactor authentication can enhance the security of a cloud service that can be accessed from anywhere, as it can prevent unauthorized access even if the password is compromised or stolen. Multifactor authentication can also protect the cloud service from phishing, brute force, or replay attacks, as well as comply with regulatory or industry standards.

Multifactor authentication is different from other options, such as replication, single sign-on, or data locality. Replication is the process of copying data or resources across multiple locations, such as regions, zones, or data centers, to improve availability, performance, or backup. Single sign-on is a user authentication method that allows users to access multiple cloud services with one set of credentials, such as username and password. Data locality is the principle of storing data close to where it is used, such as in the same region, country, or jurisdiction, to improve performance, security, or compliance. While these options may also have some benefits for a cloud service that can be accessed from anywhere, they do not directly address the security concern, which is the focus of the question. References: What is MFA? - Multi-Factor Authentication and 2FA Explained - AWS, Multi-Factor Authentication (MFA) for IAM - aws.amazon.com, Multi-Factor Authentication & Single Sign-On | Duo Security
