Inform the management and legal teams about the data breach: Incident response best practices and legal/regulatory requirements (like GDPR) mandate that management and legal teams are informed promptly following a data breach. This allows the organization to initiate appropriate communication plans, understand legal obligations, and coordinate the overall response.
Modify the firewall rules to block the IP addresses and update the ports: This is a critical containment step in the incident response process. Blocking the malicious IP addresses and closing the exploited ports helps to prevent further unauthorized access and stop the spread of the ransomware or data exfiltration, thus limiting the impact of the incident.

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Adopting PaaS can significantly reduce the management overhead of servers and networks.

Cryptojacking occurs when an attacker exploits cloud resources to mine cryptocurrency without the owner's consent. This typically results in high CPU utilization across multiple VMs while keeping network usage relatively low, as mining operations are CPU/GPU-intensive but do not require significant network bandwidth. The cloud engineer should investigate running processes and check for unauthorized mining activities.

TLSv1.3 is a newer version of the Transport Layer Security (TLS) protocol that is not supported by all operating systems. If the customers are using an unsupported OS, they will not be able to connect to the website because their browsers will not be able to negotiate a TLSv1.3 connection.

Configuring automatic elasticity is the best approach to manage an e-commerce website that experiences random performance drops due to variable traffic. Automatic elasticity enables the cloud resources to scale up or down automatically based on the current load, ensuring consistent performance even during unexpected traffic surges.
