NEW QUESTION # 27
A mid-sized company uses Azure as its primary cloud provider for its infrastructure. Its cloud security analysts are responsible for monitoring security events across multiple Azure resources (subscriptions, VMs, Storage, and SQL databases) and getting threat intelligence and intelligent security analytics throughout their organization. Which Azure service would the security analysts use to achieve their goal of having a centralized view of all the security events and alerts?
Answer: C
Explanation:
Azure Sentinel is a scalable, cloud-native, security information event management (SIEM) and security orchestration automated response (SOAR) solution. It provides intelligent security analytics and threat intelligence across the enterprise, making it the ideal service for cloud security analysts to have a centralized view of all security events and alerts.
Here's how Azure Sentinel can be utilized:
* Centralized Security Management: Azure Sentinel aggregates data from all Azure resources, including subscriptions, VMs, Storage, and SQL databases.

NEW QUESTION # 28
TeratInfo Pvt. Ltd. is an IT company that develops software products and applications for financial organizations. Owing to the cost-effective storage features and robust services provided by cloud computing, TeratInfo Pvt. Ltd. adopted cloud-based services. Recently, its security team observed a dip in the organizational system performance. Susan, a cloud security engineer, reviewed the list of publicly accessible resources, security groups, routing tables, ACLs, subnets, and IAM policies. What is this process called?
Answer: A
Explanation:
The process that Susan, a cloud security engineer, is performing by reviewing the list of publicly accessible resources, security groups, routing tables, ACLs, subnets, and IAM policies is known as performing cloud reconnaissance.
Cloud Reconnaissance: This term refers to the process of gathering information about the cloud environment to identify potential security issues. It involves examining the configurations and settings of cloud resources to detect any misconfigurations or vulnerabilities that could be exploited by attackers.
Purpose of Cloud Reconnaissance:
Identify Publicly Accessible Resources: Determine if any resources are unintentionally exposed to the public internet.
Review Security Groups and ACLs: Check if the access control lists (ACLs) and security groups are correctly configured to prevent unauthorized access.
Examine Routing Tables and Subnets: Ensure that network traffic is being routed securely and that subnets are configured to segregate resources appropriately.
Assess IAM Policies: Evaluate identity and access management (IAM) policies to ensure that they follow the principle of least privilege and do not grant excessive permissions.
Outcome of Cloud Reconnaissance: The outcome of this process should be a comprehensive understanding of the cloud environment's security posture, which can help in identifying and mitigating potential security risks.

NEW QUESTION # 29
Terry Diab has an experience of 6 years as a cloud security engineer. She recently joined a multinational company as a senior cloud security engineer. Terry learned that there is a high probability that her organizational applications could be hacked and user data such as passwords, usernames, and account information can be exploited by an attacker. The organizational applications have not yet been hacked, but this issue requires urgent action. Therefore, Terry, along with her team, released a software update that is designed to resolve this problem instantly with a quick-release procedure. Terry successfully fixed the problem (bug) in the software product immediately without following the normal quality assurance procedures. Terry's team resolved the problem immediately on the live system with zero downtime for users. Based on the given information, which of the following type of update was implemented by Terry?
Answer: B
Explanation:
A hotfix is a type of update that is used to address a specific issue or bug in a software product. It is typically released quickly and outside of the normal release schedule to resolve problems that are deemed too urgent to wait for the next regular update.
* Urgent Release: Terry's team released a software update urgently, which is characteristic of a hotfix.
* Immediate Fix: The update was designed to resolve the problem instantly, which aligns with the purpose of a hotfix.
* Bypassing Normal Procedures: Hotfixes are often released without following the normal quality assurance procedures due to the urgency of the fix.
* Zero Downtime: The problem was resolved on the live system with zero downtime, which is a critical aspect of hotfix deployment.
References:Hotfixes are used in the software industry to quickly patch issues that could potentially lead to security vulnerabilities or significant disruptions in service. They are applied to live systems, often without requiring a restart, to ensure continuous operation while the issue is being addressed.
NEW QUESTION # 30
Kevin Ryan has been working as a cloud security engineer over the past 2 years in a multinational company, which uses AWS-based cloud services. He launched an EC2 instance with Amazon Linux AMI. By disabling password-based remote logins, Kevin wants to eliminate all possible loopholes through which an attacker can exploit a user account remotely. To disable password-based remote logins, using the text editor, Kevin opened the /etc/ssh/sshd_config file and found the #PermitRootLogin yes line. Which of the following command lines should Kevin use to change the #PermitRootLogin yes line to disable password-based remote logins?
Answer: B
Explanation:
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.
Reference:
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.
NEW QUESTION # 31
An organization wants to detect its hidden cloud infrastructure by auditing its cloud environment and resources such that it shuts down unused/unwanted workloads, saves money, minimizes security risks, and optimizes its cloud inventory. In this scenario, which standard is applicable for cloud security auditing that enables the management of customer data?
Answer: B
Explanation:
ISO 27001 & 27002 standards are applicable for cloud security auditing that enables the management of customer data. These standards provide a framework for information security management practices and controls within the context of the organization's information risk management processes.
ISO 27001: This is an international standard on how to manage information security. It provides requirements for an information security management system (ISMS) and is designed to ensure the selection of adequate and proportionate security controls.
ISO 27002: This standard supplements ISO 27001 by providing a reference set of generic information security controls including best practices in information security.
Auditing and Management: Both standards include guidelines and principles for initiating, implementing, maintaining, and improving information security management within an organization, which is essential for auditing and managing customer data.
Risk Assessment: They emphasize the importance of assessing IT risks as part of the audit process, ensuring that any hidden infrastructure or unused workloads are identified and managed appropriately.
Reference:
ISO 27001 & 27002 standards are recognized globally and are often used as a benchmark for assessing and auditing information security management systems, making them suitable for organizations looking to optimize their cloud inventory and manage customer data securely12.
