Which field is automatically added to search results when assets are properly defined and enabled in Splunk Enterprise Security?
Correct Answer:C
In Splunk Enterprise Security, when assets are properly defined and enabled, the fieldsrc_categoryis automatically added to search results. This field categorizes the source IP addresses according to their asset classification, which helps in analyzing and filtering search results based on the type of assets involved in an event. Proper asset and identity management within Splunk ES enhances the ability to contextualize and prioritize security incidents.
An analyst is looking at Web Server logs, and sees the following entry as the last web request that a server processed before unexpectedly shutting down: 147.186.119.107 - - [28/Jul/2006:10:27:10 -0300] "POST /cgi-bin/shutdown/ HTTP/1.0" 200 3333
What kind of attack is most likely occurring?
Correct Answer:B
The log entry indicates aPOST /cgi-bin/shutdown/request, which suggests that a command was sent to shut down the server via a CGI script. This kind of activity is indicative of aDenial of Service (DoS) attackbecause it involves sending a specific command that causes the server to stop functioning or shut down. This is different from a Distributed Denial of Service (DDoS) attack, which typically involves overwhelming the server with traffic rather than exploiting a specific command.
A successful Continuous Monitoring initiative involves the entire organization. When an analyst discovers the need for more context or additional information, perhaps from additional data sources or altered correlation rules, to what role would this request generally escalate?
Correct Answer:C
In a successful Continuous Monitoring initiative, when an analyst identifies the need for more context or additional information, the request typically escalates to aSecurity Engineer. Security Engineers are responsible for the integration and configuration of additional data sources, and they can alter correlation rules or enhance data ingestion pipelines to provide the necessary context for analysts.
✑ Security Engineer:
✑ Incorrect Options:
✑ Continuous Monitoring Best Practices:Industry standards emphasize the role of Security Engineers in maintaining and enhancing security monitoring systems.
Role
An analyst is attempting to investigate a Notable Event within Enterprise Security. Through the course of their investigation they determined that the logs and artifacts needed to investigate the alert are not available.
What event disposition should the analyst assign to the Notable Event?
Correct Answer:D
In this scenario, the analyst cannot conclude whether the Notable Event is a true positive or a false positive due to the absence of necessary logs and artifacts. The appropriate eventdisposition in this case is "Other," as it indicates that further action is required, such as ingesting the missing logs. The involvement of a security engineer to ensure the necessary data is available for proper investigation is implied, making "Other" the most suitable option.
What is the following step-by-step description an example of?
* 1. The attacker devises a non-default beacon profile with Cobalt Strike and embeds this within a document.
* 2. The attacker creates a unique email with the malicious document based on extensive research about their target.
* 3. When the victim opens this document, a C2 channel is established to the attacker??s temporary infrastructure on a compromised website.
Correct Answer:D
The step-by-step description provided is an example of aTechniqueas defined in the MITRE ATT&CK framework. Techniques are the specific methods adversaries use to achieve their objectives during an attack, such as establishing command and control (C2) channels or delivering payloads via phishing emails. In this scenario, the attacker uses a non-default beacon profile in Cobalt Strike, sends a malicious document via email, and establishes a C2 channel once the victim interacts with the document, all of which are examples of adversary techniques.
