An organization, PARADIGM PlayStation, moved its infrastructure to a cloud as a security practice. It established an incident response team to monitor the hosted websites for security issues. While examining network access logs using SIEM, the incident response team came across some incidents that suggested that one of their websites was targeted by attackers and they successfully performed an SQL injection attack.
Subsequently, the incident response team made the website and database server offline. In which of the following steps of the incident response lifecycle, the incident team determined to make that decision?
- A. Analysis
- B. Containment
- C. Coordination and information sharing
- D. Post-mortem
Answer: B
Explanation:
The decision to take the website and database server offline falls under the Containment phase of the incident response lifecycle. Here's how the process typically unfolds:
* Detection: The incident response team detects a potential security breach, such as an SQL injection attack, through network access logs using SIEM.
* Analysis: The team analyzes the incident to confirm the breach and understand its scope and impact.
* Containment: Once confirmed, the team moves to contain the incident to prevent further damage. This includes making the affected website and database server offline to stop the attack from spreading or causing more harm1.
* Eradication and Recovery: After containment, the team works on eradicating the threat and recovering the systems to normal operation.
* Post-Incident Activity: Finally, the team conducts a post-mortem analysis to learn from the incident and improve future response efforts.

* Google Cloud VPC Service Controls Overview
VPC Service Controls enable clients to define a security perimeter around Google Cloud Platform resources to control communication to and from those resources. By using VPC Service Controls, the client can restrict access to GCP resources to a specified IP range.
* Create a Service Perimeter: The client can create a service perimeter that includes the GCP resources they want to protect.
* Define Access Levels: Within the service perimeter, the client can define access levels based on attributes such as IP address ranges.
* Enforce Access Policies: Access policies are enforced, which restrict access to the resources within the service perimeter to only those requests that come from the specified IP range.
* Grant Access to Auditors: The client can grant access to company auditors by including their IP addresses in the allowed range.
References:VPC Service Controls provide a way to secure sensitive data and enforce a perimeter around GCP resources. It is designed to prevent data exfiltration and manage access to services within the perimeter based on defined criteria, such as source IP address12. This makes it the appropriate service for the client's requirement to restrict access to a specified IP range.
NEW QUESTION # 97
Karen Gillan has recently joined an IT company as a cloud security engineer. Her organization would like to adopt cloud-based services to provide 24 x 7 customer support to its clients. It wants to transfer its customer database and transaction details along with the applications used for managing and supporting its customers.
Before migrating to cloud, which of the following analyses should be performed by Karen on the security capabilities and services provided by cloud service providers to understand the security requirements of the organization and those provided by the cloud service provider?
- A. Domain Analysis
- B. Gap Analysis
- C. Artificial Intelligence Analysis
- D. Business Impact Analysis
Answer: D
Explanation:
Before migrating to cloud services, Karen Gillan should perform a Gap Analysis to understand the security requirements of her organization and compare them with the security capabilities and services provided by cloud service providers.
Gap Analysis Purpose: A Gap Analysis is used to compare the current state of an organization's security posture against a desired future state or standard. This analysis helps identify the gaps in security that need to be addressed before moving to the cloud1.
Conducting Gap Analysis:
Assess Current Security Posture: Karen should evaluate the existing security measures, including data security practices, access controls, and incident response plans.
Identify Security Requirements: Determine the security requirements for the customer database and transaction details, as well as the applications used for managing and supporting customers.
Compare with Cloud Provider's Offerings: Review the security capabilities and services offered by the cloud service providers to see if they meet the organization's security requirements.
Identify Gaps: Highlight any discrepancies between the organization's security needs and the cloud provider's offerings.
Outcome of Gap Analysis: The outcome will be a clear understanding of what security measures are in place, what is lacking, and what the cloud provider can offer. This will guide Karen in making informed decisions about additional security controls or changes needed for a secure cloud migration.
