When an IT company suspects that a VM called Ubuntu18 in the Production-group has been compromised, it is essential to perform a forensic investigation. The process of taking a snapshot and ensuring its integrity and accessibility involves several steps:

1.Snapshot Creation: First, create a snapshot of the OS disk of the suspect VM, named ubuntudisksnap. This snapshot is a point-in-time copy of the VM's disk, ensuring that all data at that moment is captured.

1.Snapshot Security: Next, to transfer this snapshot securely to a storage account under the Security-group, a shared access signature (SAS) needs to be generated. A SAS provides delegated access to Azure storage resources without exposing the storage account keys.

1.Data Transfer: With the SAS token, the snapshot can be securely copied to a storage account in the Security-group. This method ensures that only authorized personnel can access the snapshot for further investigation.

1.Further Analysis: After copying the snapshot, it can be mounted onto a forensic workstation for detailed examination. This step involves examining the contents of the snapshot for any malicious activity or artifacts left by the attacker.

Generating a shared access signature is a critical step in ensuring that the snapshot can be securely accessed and transferred without compromising the integrity and security of the data.

In the context of a security incident within the GCP environment of Magnitude IT Solutions, the Google Data Incident Response Team would be organized to address various aspects of the incident effectively. Among the team, the role with the authoritative knowledge of incidents and involvement in different domains such as security, legal, product, and digital forensics is the Incident Commander. Here's why:

1.Authority and Responsibility: The Incident Commander (IC) is typically responsible for the overall management of the incident response. This includes making critical decisions, coordinating the efforts of the entire response team, and ensuring that all aspects of the incident are addressed.

1.Cross-Functional Involvement: The IC has the expertise and authority to interact with various domains such as security (to understand and mitigate threats), legal (to ensure compliance and manage legal risks), product (to understand the impact on services), and digital forensics (to guide the investigation and evidence collection).

1.Leadership and Coordination: The IC leads the response effort, ensuring that all team members, including Subject Matter Experts (SMEs), Operations Leads, and Communications Leads, are working in sync and that the incident response plan is effectively executed.

1.Communication: The IC is the primary point of contact for internal and external stakeholders, ensuring clear and consistent communication about the status and actions being taken in response to the incident.

In summary, the Incident Commander is the central figure with the authoritative knowledge and cross-functional involvement necessary to manage a security incident comprehensively.

Daffod, as an American cloud service provider complying with the cloud computing law that emphasizes the importance of information security for economic and national security interests, adheres to the Federal Information Security Management Act (FISMA). Here's why:

1.FISMA Overview: FISMA is a US law enacted to protect government information, operations, and assets against natural or man-made threats.

1.Importance of Information Security: FISMA requires that all federal agencies develop, document, and implement an information security and protection program.

1.Relevance to Daffod: As Daffod complies with this law, it ensures that its cloud services are secure and adhere to national security standards, making it a trusted provider for secure and cost-effective cloud services.

To disable user account passwords on an Amazon EC2 Linux instance, Simon should use the command passwd -L <USERNAME>. Here's the detailed explanation:

1.passwd Command: The passwd command is used to update a user's authentication tokens (passwords).

1.-L Option: The -L option is used to lock the password of the specified user account, effectively disabling the password without deleting the user account itself.

1.Security Measure: Disabling passwords ensures that the user cannot authenticate using a password, thereby enhancing the security of the instance.

For an organization with resources on Google Cloud that needs to ensure high availability and reduce downtime, the high availability settings of Google Cloud SQL should be checked. Here's the detailed explanation:

1.Google Cloud SQL Overview: Cloud SQL is a fully-managed relational database service for MySQL, PostgreSQL, and SQL Server. It provides high availability configurations and automated backups.

1.High Availability Configuration: Cloud SQL offers high availability through regional instances, which replicate data across multiple zones within a region to ensure redundancy.

1.Testing Backups: Regularly testing backups and their configurations ensures that the high availability settings are functioning correctly and that data recovery is possible in case of an outage.

When Shannon Elizabeth enables Just-In-Time (JIT) VM access on the myprodvm virtual machine from the Azure Security Center dashboard, the following happens:

1.Inbound Traffic Control: JIT VM access locks down the inbound traffic to the virtual machine.

1.Azure Firewall Rule: It creates a rule in the Azure firewall to control this inbound traffic, allowing access only when required and for a specified duration.

1.Enhanced Security: This approach minimizes exposure to potential attacks by reducing the time that the VM ports are open.
