In the context of forensic acquisition of a compromised Azure VM, it is crucial to maintain the integrity of the evidence. The backup copy of the snapshot should be taken before any operations that could potentially alter the data are performed. This means creating the backup copy in a blob container as a page blob before mounting the snapshot onto the forensic workstation.

Here’s the process:

Create Snapshot: First, a snapshot of the VM’s disk is created to capture the state of the VM at the point of compromise.

Backup Copy: Before the snapshot is mounted onto the forensic workstation for analysis, a backup copy of the snapshot should be taken and stored in a blob container as a page blob.

Maintain Integrity: This step ensures that the original snapshot remains unaltered and can be used as evidence, maintaining the chain of custody.

Forensic Analysis: After the backup copy is secured, the snapshot can be mounted onto the forensic workstation for detailed analysis.

Documentation: All steps taken during the forensic acquisition process should be thoroughly documented for legal and compliance purposes.

Crypto-shredding is the method of ‘deleting’ encrypted data by destroying the encryption keys. This method is particularly useful in cloud environments where physical destruction of storage media is not feasible. By deleting the keys used to encrypt the data, the data itself becomes inaccessible and is effectively considered deleted.

Here’s how crypto-shredding works:

Encryption: Data is encrypted using cryptographic keys, which are essential for decrypting the data to make it readable.

Key Management: The keys are managed separately from the data, often in a secure key management system.

Deletion of Keys: When instructed to delete the data, instead of trying to erase the actual data, the encryption keys are deleted.

Data Inaccessibility: Without the keys, the encrypted data cannot be decrypted, rendering it unreadable and unrecoverable.

Compliance: This method helps organizations comply with data protection regulations that require secure deletion of personal data.

The Warm Standby approach in disaster recovery is designed to achieve lower Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) values. This approach involves having a scaled-down version of a fully functional environment running at all times in the cloud. In the event of a disaster, the system can quickly switch over to the warm standby environment, which is already running and up-to-date, thus ensuring a quick and complete restoration of applications.

Here’s how the Warm Standby approach works:

Prepared Environment: A duplicate of the production environment is running in the cloud, but at a reduced capacity.

Quick Activation: In case of a disaster, this environment can be quickly scaled up to handle the full production load.

Data Synchronization: Regular data synchronization ensures that the standby environment is always up-to-date, which contributes to a low RPO.

Reduced Downtime: Because the standby system is always running, the time to switch over is minimal, leading to a low RTO.

Cost-Efficiency: While more expensive than a cold standby, it is more cost-effective than a hot standby, balancing cost with readiness.

References:

An article discussing the importance of RPO and RTO in disaster recovery and how different strategies, including Warm Standby, impact these metrics1.

Amazon EC2: Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It allows users to run virtual servers and manage storage, security, and networking1.

IaaS Definition: IaaS provides virtualized computing resources over the internet. In an IaaS model, a cloud provider hosts the infrastructure components traditionally present in an on-premises data center, including servers, storage, and networking hardware1.

EC2 as IaaS: Amazon EC2 falls under the IaaS category because it provides the hardware infrastructure, allows users to scale computing capacity up or down, and users pay only for the capacity they use1.

Exclusion of Other Models: EC2 is not PaaS because it does not provide a platform for developing, running, or managing applications. It’s not SaaS as it doesn’t deliver software over the internet. DaaS, or Desktop as a Service, provides virtual desktops, which is not the service EC2 offers1.

The Warm Standby approach in disaster recovery involves running a scaled-down version of a fully functional environment in the cloud. This method is activated quickly in case of a disaster, ensuring that the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) are within minutes.

Scaled-Down Environment: A smaller version of the production environment is always running in the cloud. This includes a minimal number of resources required to keep the application operational12.

Quick Activation: In the event of a disaster, the warm standby environment can be quickly scaled up to handle the full production load12.

RTO and RPO: The warm standby approach is designed to achieve an RTO and RPO within minutes, which is essential for business-critical functions12.

Business Continuity: This approach ensures that core business functions continue to operate with minimal disruption during and after a disaster12.

References:Warm Standby is a disaster recovery strategy that provides a balance between cost and downtime. It is less expensive than a fully replicated environment but offers a faster recovery time than cold or pilot light approaches12. This makes it suitable for organizations that need to ensure high availability and quick recovery for their critical systems.

To encrypt the traffic between the load balancer and clients that initiate SSL or TLS sessions, SecAppSol Pvt. Ltd.'s security team would enable an HTTPS listener on their load balancer. This is a common method used in AWS to secure communication.

Here’s how it works:

HTTPS Listener Configuration: The security team configures the load balancer with an HTTPS listener, which listens for incoming SSL or TLS connections on a specified port (usually port 443).

SSL/TLS Certificates: They deploy SSL/TLS certificates on the load balancer. These certificates are used to establish a secure connection and encrypt the traffic.

Secure Communication: When a client initiates a session, the HTTPS listener uses the SSL/TLS certificate to perform a handshake, establish a secure connection, and encrypt the data in transit.

Backend Encryption: Optionally, the load balancer can also be configured to encrypt traffic to the backend servers, ensuring end-to-end encryption.

Security Policies: The security team sets security policies on the load balancer to define the ciphers and protocols used for SSL/TLS, further enhancing security.
