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.

Amazon Simple Queue Service (Amazon SQS) supports server-side encryption (SSE) to protect the contents of messages in queues using SQS-managed encryption keys or keys managed in the AWS Key Management Service (AWS KMS).

Enable SSE on Amazon SQS: When you create a new queue or update an existing queue, you can enable SSE by selecting the option for server-side encryption.

Choose Encryption Keys: You can choose to use the default SQS-managed keys (SSE-SQS) or select a custom customer-managed key in AWS KMS (SSE-KMS).

Secure Data Transmission: With SSE enabled, messages are encrypted as soon as Amazon SQS receives them and are stored in encrypted form.

Decryption for Authorized Consumers: Amazon SQS decrypts messages only when they are sent to an authorized consumer, ensuring the security of the message contents during transit.

References:Amazon SQS provides server-side encryption to protect sensitive data in queues, using either SQS-managed encryption keys or customer-managed keys in AWS KMS1. This feature helps in meeting strict encryption compliance and regulatory requirements, making it suitable for scenarios where secure message transmission is critical12.

To disable password-based remote logins for the root account on an EC2 instance running Amazon Linux AMI, Kevin should modify the SSH configuration as follows:

Open SSH Configuration: Using a text editor, open the /etc/ssh/sshd_config file.

Find PermitRootLogin Directive: Locate the line #PermitRootLogin yes. The # indicates that the line is commented out.

Modify the Directive: Change the line to PermitRootLogin without-password. This setting allows root login using authentication methods other than passwords, such as SSH keys, while disabling password-based root logins.

Save and Close: Save the changes to the sshd_config file and exit the text editor.

Restart SSH Service: To apply the changes, restart the SSH service by running sudo service sshd restart or sudo systemctl restart sshd, depending on the system’s init system.

References:The PermitRootLogin without-password directive in the SSH configuration file is used to enhance security by preventing password-based authentication for the root user, which is a common target for brute force attacks. Instead, it requires more secure methods like SSH key pairs for authentication. This change is part of best practices for securing SSH access to Linux servers.

Chris Noth is looking to manage user identities and automate the provisioning and de-provisioning of users in cloud-based services and applications. The IAM standard that supports this functionality is SCIM (System for Cross-domain Identity Management).

SCIM Overview: SCIM is an open standard designed to manage user identity information across different domains. It simplifies user management in cloud-based applications and services by allowing for automated user provisioning and de-provisioning1.

Automated Provisioning: With SCIM, when new users are added to an organization’s system, their identities can be automatically provisioned across various cloud services without manual intervention1.

Automated De-provisioning: Similarly, when users leave the organization or their roles change, SCIM can ensure that their access is automatically revoked or adjusted across all connected services. This reduces the risk of former employees retaining access to sensitive systems and data1.

Why Not the Others?:

XACML (eXtensible Access Control Markup Language) is used for defining access control policies, not for identity provisioning.

OpenID is an authentication standard that allows users to be authenticated by certain co-operating sites using a third-party service, without the need for passwords.

OAuth is an open standard for access delegation, commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords.

Aidan McGraw’s requirements to protect sensitive information shared outside the organization can be satisfied by Information Rights Management (IRM).

IRM Overview: IRM is a form of IT security technology used to protect documents containing sensitive information from unauthorized access. It does this by encrypting the data and embedding user permissions directly into the file1.

Encryption and Permissions: IRM allows for the encryption of the actual data within the file and includes access permissions that dictate who can view, edit, print, forward, or take other actions with the data. These permissions are enforced regardless of where the file is located, making it ideal for sharing outside the organization1.

Protection Against Attacks: By using IRM, Aidan ensures that even if attackers were to gain access to the file, they would not be able to decrypt the information without the appropriate permissions. This protects against unauthorized intruders and hackers1.
