NEW QUESTION # 106
You are the cybersecurity lead for an International financial institution. Your organization offers online banking services to millions of customers globally, and you have recently migrated your core banking system to a hybrid cloud environment to enhance scalability and cost efficiencies.
One evening, after a routine system patch, there is a surge in server-side request forgery (SSRF) alerts from your web application firewall(WAF). Simultaneously, your intrusion detection system (IDS) flags possible attempts to interact with cloud metadata services from your application layer, which could expose sensitive cloud configuration details and API keys. This Is a clear Indication that attackers might be trying to leverage the SSRF vulnerability to breach your cloud infrastructure. Considering the critical nature of your services and the high stakes involved, how should you proceed to tackle this imminent threat while ensuring minimal disruption to your banking customers?
- A. Notify all banking customers about the potential security incident, urging them to change their passwords and monitor their accounts for any unauthorized activity.
- B. Isolate the affected cloud servers and redirect traffic to backup servers, ensuring continuous service while initiating a deep-dive analysis of the suspicious activities using cloud-native security tools.
- C. Engage with a third-party cybersecurity firm specializing in cloud security to conduct an emergency audit, relying on its expertise to identify the root cause and potential breaches.
- D. Rollback the recent patch immediately and inform the cloud service provider about potential unauthorized access to gauge the extent of vulnerability and coordinate a joint response.
Answer: B
Explanation:
In response to the SSRF alerts and potential breach attempts flagged by your IDS, the immediate priority is to contain the threat while maintaining the integrity of your services. Here's a step-by-step approach:
* Isolation and Containment:
* Isolate Affected Servers: Disconnect the affected cloud servers from the network to prevent further unauthorized access or data exfiltration.
* Redirect Traffic: Redirect incoming traffic to backup servers that are not compromised to ensure that online banking services remain available to customers.
* Deep-Dive Analysis:
* Cloud-Native Security Tools: Utilize cloud-native security tools provided by your cloud service provider (such as AWS GuardDuty, Azure Security Center, or Google Cloud Security Command Center) to conduct a thorough investigation of the suspicious activities.
* Examine Network Logs: Analyze network logs to identify the attack vectors and understand the scope of the attack.
* Coordinate with Cloud Provider:
* Joint Response: Inform your cloud service provider about the incident to collaborate on identifying and mitigating the vulnerability. Cloud providers often have additional tools and expertise that can be leveraged during a security incident.
* Remediation:
* Patch and Harden Systems: Once the root cause is identified, apply necessary patches and harden the security posture of your cloud infrastructure to prevent similar attacks in the future.
* Communication:
* Internal Stakeholders: Keep internal stakeholders, including the executive team and legal department, informed about the incident and the steps being taken to address it.

NEW QUESTION # 111
SecuraCorp, a leading financial institution, is worried about zero-day vulnerabilities. With a sprawling network infrastructure and multiple transaction points, it needs a system that does not solely rely on signatures but can effectively identify suspicious patterns based on the behavior in the network. Which type of IDS/IPS should SecuraCorp primarily deploy for its needs?
- A. Anomaly-based IDS
- B. Signature-based IDS
- C. Network-based IDS
- D. Host-based IDS
Answer: A
Explanation:
SecuraCorp needs an Intrusion Detection System (IDS) that can identify suspicious patterns based on behavior rather than relying solely on known signatures. Here's why an Anomaly-based IDS is the best fit:
* Anomaly-based IDS:
* Behavior Analysis: Detects deviations from normal network behavior, which is crucial for identifying zero-day vulnerabilities.
* Pattern Recognition: Uses machine learning and statistical methods to identify unusual patterns that might indicate malicious activity.
* Advantages: Effective against unknown threats and zero-day exploits because it does not rely on predefined signatures.
* Network-based IDS: Primarily monitors network traffic but often relies on signatures, making it less effective against unknown threats.
* Signature-based IDS: Relies on a database of known attack signatures, which is not sufficient for detecting new or unknown threats.
* Host-based IDS: Monitors individual systems but might not provide a comprehensive view of the network.

* EC-Council Certified Security Analyst (ECSA) materials.
NEW QUESTION # 112
Ruben, a crime investigator, wants to retrieve all the deleted files and folders in the suspected media without affecting the original files. For this purpose, he uses a method that involves the creation of a cloned copy of the entire media and prevents the contamination of the original media.
Identify the method utilized by Ruben in the above scenario.
- A. Bit-stream imaging
- B. Sparse acquisition
- C. Logical acquisition
- D. Drive decryption
Answer: A
Explanation:
Bit-stream imaging is the method utilized by Ruben in the above scenario. Bit-stream imaging is a method that involves creating a cloned copy of the entire media and prevents the contamination of the original media.
Bit-stream imaging copies all the data on the media, including deleted files and folders, hidden partitions, slack space, etc., at a bit level. Bit-stream imaging preserves the integrity and authenticity of the digital evidence and allows further analysis without affecting the original media. Sparse acquisition is a method that involves creating a partial copy of the media by skipping empty sectors or blocks. Drive decryption is a method that involves decrypting an encrypted drive or partition using a password or a key. Logical acquisition is a method that involves creating a copy of the logical files and folders on the media using file system commands.
