The pandas I/O API is a set of top level reader functions accessed likepandas.read_csv() that generally return a pandas object. The correspondingwriter functions are object methods that are accessed likeDataFrame.to_csv(). Below is a table containing available readers andwriters.
If a filepath is provided for filepath_or_buffer, map the file objectdirectly onto memory and access the data directly from there. Using thisoption can improve performance because there is no longer any I/O overhead.
When dealing with remote storage systems, you might needextra configuration with environment variables or config files inspecial locations. For example, to access data in your S3 bucket,you will need to define credentials in one of the several ways listed inthe S3Fs documentation. The same is truefor several of the storage backends, and you should follow the linksat fsimpl1 for implementations built into fsspec and fsimpl2for those not included in the main fsspecdistribution.
Today, if you navigate from an alert to Threat Explorer, it opens a filtered view within the Explorer, with the view filtered by Alert policy ID (policy ID being a unique identifier for an Alert policy).We are making this integration more relevant by introducing the alert ID (see an example of alert ID below) in Threat Explorer and Real-time detections so that you see messages which are relevant to the specific alert, as well as a count of emails. You will also be able to see if a message was part of an alert, as well as navigate from that message to the specific alert.
As part of this change, you will be able to search for, and filter email data across 30 days (an increase from the previous 7 days) in Threat Explorer/Real-time detections for both Defender for Office P1 and P2 trial tenants.This does not impact any production tenants for both P1 and P2/E5 customers, which already have the 30 day data retention and search capabilities.
As part of this update, the number of rows for Email records that can be exported from Threat Explorer is increased from 9990 to 200,000 records. The set of columns that can be exported currently will remain the same, but the number of rows will increase from the current limit.
To view the individual tags for sender and recipient, select the subject to open the message details flyout. On the Summary tab, the sender and recipient tags are shown separately, if they're present for an email.The information about individual tags for sender and recipient also extends to exported CSV data, where you can see these details in two separate columns.
Tags information is also shown in the URL clicks flyout. To view it, go to Phish or All Email view and then to the URLs or URL Clicks tab. Select an individual URL flyout to view additional details about clicks for that URL, including tags associated with that click.
We've focused on platform and data-quality improvements to increase data accuracy and consistency for email records. Improvements include consolidation of pre-delivery and post-delivery information, such as actions executed on an email as part of the ZAP process, into a single record. Additional details like spam verdict, entity-level threats (for example, which URL was malicious), and latest delivery locations are also included.
In addition to showing malware and phishing threats, you see the spam verdict associated with an email. Within the email, see all the threats associated with the email along with the corresponding detection technologies. An email can have zero, one, or multiple threats. You'll see the current threats in the Details section of the email flyout. For multiple threats (such as malware and phishing), the Detection tech field shows the threat-detection mapping, which is the detection technology that identified the threat.
The set of detection technologies now includes new detection methods, as well as spam-detection technologies. You can use the same set of detection technologies to filter the results across the different email views (Malware, Phish, All Email).
Verdict analysis might not necessarily be tied to entities. As an example, an email might be classified as phish or spam, but there are no URLs that are stamped with a phish/spam verdict. This is because the filters also evaluate content and other details for an email before assigning a verdict.
Currently, we surface delivery location in the email grid and email flyout. The Delivery location field is getting renamed Original delivery location. And we're introducing another field, Latest delivery location.
Original delivery location will give more information about where an email was delivered initially. Latest delivery location will state where an email landed after system actions like ZAP or admin actions like Move to deleted items. Latest delivery location is intended to tell admins the message's last-known location post-delivery or any system/admin actions. It doesn't include any end-user actions on the email. For example, if a user deleted a message or moved the message to archive/pst, the message \"delivery\" location won't be updated. But if a system action updated the location (for example, ZAP resulting in an email moving to quarantine), Latest delivery location would show as \"quarantine.\"
You might see Delivery location as \"delivered\" and Delivery location as \"unknown\" if the message was delivered, but an Inbox rule moved the message to a default folder (such as Draft or Archive) instead of to the Inbox or Junk Email folder.
Additional actions were applied after delivery of the email. They can include ZAP, manual remediation (action taken by an Admin such as soft delete), Dynamic Delivery, and reprocessed (for an email that was retroactively detected as good).
As part of the pending changes, the \"Removed by ZAP\" value currently surfaced in the Delivery Action filter is going away. You'll have a way to search for all email with the ZAP attempt through Additional actions.
Allowed by org policy: The organization's security teams set policies or Exchange mail flow rules (also known as transport rules) to allow senders and domains for users in their organization. This can be for a set of users or the entire organization.
Blocked by org policy: The organization's security teams set policies or mail flow rules to block senders, domains, message languages, or source IPs for users in their organization. This can be applied to a set of users or the entire organization.
File extension blocked by org policy: An organization's security team blocks a file name extension through the anti-malware policy settings. These values will now be displayed in email details to help with investigations. Secops teams can also use the rich-filtering capability to filter on blocked file extensions.
Phish confidence level helps identify the degree of confidence with which an email was categorized as \"phish.\" The two possible values are High and Normal. In the initial stages, this filter will be available only in the Phish view of Threat Explorer.
The ZAP URL signal is typically used for ZAP Phish alert scenarios where an email was identified as Phish and removed after delivery. This signal connects the alert with the corresponding results in Explorer. It's one of the IOCs for the alert.
You'll see the time zone for the email records in the Portal as well as for Exported data. It will be visible across experiences like Email Grid, Details flyout, Email Timeline, and Similar Emails, so the time zone for the result set is clear.
Today we expose the list of the top targeted users in the Malware view for emails, in the Top Malware Families section. We'll be extending this view in the Phish and All Email views as well. You'll be able to see the top-five targeted users, along with the number of attempts for each user for the corresponding view. For example, for Phish view, you'll see the number of Phish attempts.
You'll be able to export the list of targeted users, up to a limit of 3,000, along with the number of attempts for offline analysis for each email view. In addition, selecting the number of attempts (for example, 13 attempts in the image below) will open a filtered view in Threat Explorer, so you can see more details across emails and threats for that user.
As part of data enrichment, you'll be able to see all the different Exchange transport rules (ETR) that were applied to a message. This information will be available in the Email grid view. To view it, select Column options in the grid and then Add Exchange Transport Rule from the column options. It will also be visible on the Details flyout in the email.
ETR search and name availability depend on the specific role that's assigned to you. You need to have one of the following roles/permissions to view the ETR names and search. If you don't have any of these roles assigned to you, you can't see the names of the transport rules or search for messages by using ETR names. However, you could see the ETR label and GUID information in the Email Details. Other record-viewing experiences in Email Grids, Email flyouts, Filters, and Export are not affected.
Connectors are a collection of instructions that customize how your email flows to and from your Microsoft 365 or Office 365 organization. They enable you to apply any security restrictions or controls. Within Threat Explorer, you can now view the connectors that are related to an email and search for emails by using connector names.
For best results, use full email addresses to search protected users. You will find your protected user quicker and more successfully if you search for firstname.lastname@contoso.com, for example, when investigating user impersonation. When searching for a protected domain the search will take the root domain (contoso.com, for example), and the domain name (contoso). Searching for the root domain contoso.com will return both impersonations of contoso.com and the domain name contoso. 781b155fdc
