Incident Handlers are typically the first line of defense against cloud security attacks, with their primary role being to respond immediately to any type of security incident. In the context of a cybersecurity attack such as a DDoS (Distributed Denial of Service), incident handlers are responsible for the initial response, which includes identifying, managing, recording, and analyzing security threats or incidents in real-time.

Here’s how Incident Handlers function as the first line of defense:

• Immediate Response: They are trained to respond quickly to security incidents to minimize impact and manage the situation.
• Incident Analysis: Incident Handlers analyze the nature and scope of the incident, including the type of attack and its origin.
• Mitigation Strategies: They implement strategies to mitigate the attack, such as rerouting traffic or isolating affected systems.
• Communication: They communicate with relevant stakeholders, including IT professionals, management, and possibly law enforcement.
• Forensics and Recovery: After an attack, they work on forensics to understand how the breach occurred and on recovery processes to restore services.

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.

• AWS documentation on creating an HTTPS listener for your Application Load Balancer, detailing the process and requirements2.

To update an existing login profile for an IAM user, the correct AWS CLI command syntax is as follows:

aws iam update-login-profile --user-name --password

Here’s the breakdown of the command:

• aws iam update-login-profile: This is the AWS CLI command to update the IAM user’s login profile.
• –user-name : The --user-name flag specifies the IAM username whose login profile Ewan wants to update.
• –password : The --password flag followed by sets the new password for the specified IAM user.

It’s important to replace with the actual username and with the new password Ewan wishes to set.

Azure Application Gateway is a web traffic load balancer that enables Sandra to manage traffic to her web applications. It is designed to distribute traffic to backend virtual machines and services based on various HTTP request attributes.

Here’s how Azure Application Gateway meets the requirements:

• Routing Based on HTTP Attributes: Application Gateway can route traffic based on URL path or host headers.
• SSL Termination: It provides SSL termination at the gateway, reducing the SSL overhead on the web servers.
• Web Application Firewall: Application Gateway includes a Web Application Firewall (WAF) that provides protection to web applications from common web vulnerabilities and exploits.
• Session Affinity: It can maintain session affinity, which is useful when user sessions need to be directed to the same server.
• Scalability and High Availability: Application Gateway supports autoscaling and zone redundancy, ensuring high availability and scalability.

• Azure’s official documentation on Application Gateway, which details its capabilities for routing traffic based on HTTP request attributes1.
