질문 # 159
A security engineer is reviewing the SIEM logs after a server crashed. The following list of events represents the timeline of actions collected from the SIEM:
Which of the following TTPs is most likely associated with this SIEM log?
정답:B
질문 # 160
During the course of normal SOC operations, three anomalous events occurred and were flagged as potential IoCs. Evidence for each of these potential IoCs is provided.
INSTRUCTIONS
Review each of the events and select the appropriate analysis and remediation options for each IoC.
정답:
설명:
Analysis and Remediation Options for Each IoC:
IoC 1:
* Evidence:
* Source: Apache_httpd
* Type: DNSQ
* Dest: @10.1.1.1:53, @10.1.2.5
* Data: update.s.domain, CNAME 3a129sk219r9slmfkzzz000.s.domain, 108.158.253.253
* Analysis:
* Analysis: The service is attempting to resolve a malicious domain.
* Reason: The DNS queries and the nature of the CNAME resolution indicate that the service is trying to resolve potentially harmful domains, which is a common tactic used by malware to connect to command-and-control servers.
* Remediation:
* Remediation: Implement a blocklist for known malicious ports.
* Reason: Blocking known malicious domains at the DNS level prevents the resolution of harmful domains, thereby protecting the network from potential connections to malicious servers.
IoC 2:
* Evidence:
* Src: 10.0.5.5
* Dst: 10.1.2.1, 10.1.2.2, 10.1.2.3, 10.1.2.4, 10.1.2.5
* Proto: IP_ICMP
* Data: ECHO
* Action: Drop
* Analysis:
* Analysis: Someone is footprinting a network subnet.
* Reason: The repeated ICMP ECHO requests to different addresses within a subnet indicate that someone is scanning the network to discover active hosts, a common reconnaissance technique used by attackers.
* Remediation:
* Remediation: Block ping requests across the WAN interface.
* Reason: Blocking ICMP ECHO requests on the WAN interface can prevent attackers from using ping sweeps to gather information about the network topology and active devices.
IoC 3:
* Evidence:
* Proxylog:
* GET /announce?info_hash=%01dff%27f%21%10%c5%wp%4e%1d%6f%63%3c%49%
6d&peer_id%3dxJFS
* Uploaded=0&downloaded=0&left=3767869&compact=1&ip=10.5.1.26&event=started
* User-Agent: RAZA 2.1.0.0
* Host: localhost
* Connection: Keep-Alive
* HTTP 200 OK
* Analysis:
* Analysis: An employee is using P2P services to download files.
* Reason: The HTTP GET request with parameters related to a BitTorrent client indicates that the employee is using peer-to-peer (P2P) services, which can lead to unauthorized data transfer and potential security risks.
* Remediation:
* Remediation: Enforce endpoint controls on third-party software installations.
* Reason: By enforcing strict endpoint controls, you can prevent the installation and use of unauthorized software, such as P2P clients, thereby mitigating the risk of data leaks and other security threats associated with such applications.
References:
* CompTIA Security+ Study Guide: This guide offers detailed explanations on identifying and mitigating various types of Indicators of Compromise (IoCs) and the corresponding analysis and remediation strategies.
* CompTIA Security+ Exam Objectives: These objectives cover key concepts in network security monitoring and incident response, providing guidelines on how to handle different types of security events.
* Security Operations Center (SOC) Best Practices: This resource outlines effective strategies for analyzing and responding to anomalous events within a SOC, including the use of blocklists, endpoint controls, and network configuration changes.
By accurately analyzing the nature of each IoC and applying the appropriate remediation measures, the organization can effectively mitigate potential security threats and maintain a robust security posture.
질문 # 161
After several companies in the financial industry were affected by a similar incident, they shared information about threat intelligence and the malware used for exploitation. Which of the following should the companies do to best indicate whether the attacks are being conducted by the same actor?
정답:D
설명:
Comprehensive and Detailed
Determining if attacks are from the same actor requires unique attribution. Let's analyze:
A . Code stylometry: Analyzes coding style to identify authorship, the best method for linking malware to a specific actor per CAS-005's threat intelligence focus.
B . Common IOCs: Indicates similar attacks but not necessarily the same actor.
C . IOC extractions: Similar to B, lacks specificity for attribution.
D . Malware detonation: Tests behavior, not authorship.
질문 # 162
A user submits a help desk ticket stating then account does not authenticate sometimes. An analyst reviews the following logs for the user:
Which of the following best explains the reason the user's access is being denied?
정답:B
설명:
The logs reviewed for the user indicate that access is being denied due to time-based access restrictions. These restrictions are commonly implemented to limit access to systems during specific hours to enhance security. If a user attempts to authenticate outside of the allowed time window, access will be denied. This measure helps prevent unauthorized access during non-business hours, reducing the risk of security incidents.
References:
* CompTIA SecurityX Study Guide: Covers various access control methods, including time-based restrictions, as a means of enhancing security.
* NIST Special Publication 800-53, "Security and Privacy Controls for Information Systems and Organizations": Recommends the use of time-based access restrictions as part of access control policies.
* "Access Control and Identity Management" by Mike Chapple and Aaron French: Discusses the implementation and benefits of time-based access restrictions.
질문 # 163
A software company deployed a new application based on its internal code repository Several customers are reporting anti-malware alerts on workstations used to test the application Which of the following is the most likely cause of the alerts?
정답:B
설명:
The most likely cause of the anti-malware alerts on customer workstations is unsecure bundled libraries. When developing and deploying new applications, it is common for developers to use third-party libraries. If these libraries are not properly vetted for security, they can introduce vulnerabilities or malicious code.
Why Unsecure Bundled Libraries?
Third-Party Risks: Using libraries that are not secure can lead to malware infections if the libraries contain malicious code or vulnerabilities.
Code Dependencies: Libraries may have dependencies that are not secure, leading to potential security risks.
Common Issue: This is a frequent issue in software development where libraries are used for convenience but not properly vetted for security.
Other options, while relevant, are less likely to cause widespread anti-malware alerts:
A . Misconfigured code commit: Could lead to issues but less likely to trigger anti-malware alerts.
C . Invalid code signing certificate: Would lead to trust issues but not typically anti-malware alerts.
D . Data leakage: Relevant for privacy concerns but not directly related to anti-malware alerts.
