Your on-premises network contains multiple devices that provide logs in Comment Event Format (CEF).
You have an Azure subscription and a MS Sentinel workspace named Workspace1.
You need to ingest the logs from the devices into Workspace1.

What should you do first?

Deploy a computer that runs Linux

-To ingest Syslog and CEF logs into MS Sentinel, particularly from devices and appliance onto which you cannot install the Log Analytics agent directly, you must designate and configure a Linux machine that will collect the logs from your devices and forward them to your MS Sentinel workspace. This machine can be a physical or VM in your on-premises environment, an Azure VM, or a VM in another cloud.

-A livestream is always based on a query. Typically, you use the query to narrow down streaming log events, so only the events that are related to your threat hunting efforts appear. You can use a livestream to:
—Test new queries against live events
—Generate notifications for threats
—Launch investigations

-In KQL, the render keyword renders results as a graphical output.
-Other keywords do not provide graphical result and have the following functions:
Print: outputs a single row with one or more scalar expressions
Project: selects the columns to include in the order specified
Extend: creates a calculated column and adds it to the result set
Summarize: groups the rows according to the by group columns and calculates aggregations over each group

Study These Flashcards

Security operations efficiency

-You can use the Security Operations efficiency workbook template to monitor SOC operations. The workbook contains many metrics, including incidents created over time and mean time to triage. These metrics are unavailable in other workbook templates, so you will minimize administrative effort if you use the Security Operations efficiency workbook template.

You need to create a Defender for Cloud Apps policy that will generate alerts based on a trainable classifier.

Which type of policy should you create?

Study These Flashcards

File Policy

-allow you to enforce a wide range of automated processes by using the cloud provider’s APIs. Policies can be set to provide continuous compliance scans, legal eDiscovery tasks, DLP for sensitive content shared publicly, and many more use cases. Defender for Cloud Apps can monitor any file type based on more than 20 metadata filters, such as access level, file type, and trainable classifiers.

You have a M365 E5 subscription that uses MS Defender for Endpoint. You deploy an app named App1. App1 clears logs from an application server. When App1 runs, it triggers a MS Defender alert.

You have a MS Sentinel workspace that contains the following rules: 1) a near-real-time (NRT) rule named Rule1 2) a fusion rule named Rule2 3) a scheduled rule named Rule3 4) a machine learning (ML) behavior analytics rule named Rule4 Which rules can you review?

Rule1 and Rule3 only -Fusion rules use a correlation engine based on scalable ML algorithms to automatically detect multistage attacks. -Because they are based on proprietary ML algorithms, you cannot see their logic. -NRT rules are designed to run once every minute and capture events ingested in the preceding minute, to supply you with information that is as up-to-the-minute as possible. -ML Behavior analytics are based on proprietary MS ML algorithms, so you cannot see or change the query logic. -Rule1 and Rule3 are not based on ML.

You have a MS Sentinel workspace that has a MS Defender for Cloud data connector. You create a MS incident creation rule named Rule1. You need to ensure that Rule1 creates incidents based on Defender for Cloud alerts. What should you configure in Rule1?

Analytics rule logic

You have a MS Sentinel workspace that contains the following query: OfficeActivity | where TimeGenerated > ago(7h) | where Operation !contains “Mail” | project TimeGenerated, UserId, Operation, OfficeWorkload, RecordType, _ResourceId | sort by TimeGenerated desc nulls last The query filters the office activity table to remove results that refer to email, and project selected information from the table in descending order. You need to create a custom parser named Parser1 that will run the query. What should you do first?

Remove | where TimeGenerated > ago(7h) -A parser should not include a filter by time. The query that uses the parser will apply the required time range.
