File names for monitoring must
In reality, there might be multiple events for a single handle, logging smaller operations that make up the overall action. For example, a rename involves a read, delete, and a write operation. The following table provides more information about each event:. Unfortunately, this is not a one-to-one mapping. Each file action includes many smaller operations that Windows performs, and those smaller operations are the ones logged.
Consider this only as a starting point. The analysis above is extremely simplified, and real-world implementation will require more research.
Some areas for further research are:. You may want to review this PowerShell Script which reads Windows events and generates from them meaningful file activity report to get a somewhat less simplified analysis.
Pro tip: Varonis has been auditing Windows file servers at petabyte scale for over a decade, with numerous patents related to normalization and analysis. Give it a try to save yourself time figuring out how to parse raw logs. While the Windows file activity events seem comprehensive, there are things that cannot be determined using only the event log.
A few examples are:. If you are going to use the native Windows file auditing, you need to be aware of how much data you are going to collect. Collecting Windows file activity is a massive event flow and the Microsoft event structure, generating many events for a single file action, does not help. The name of the file copied to the local file system. A file with the same name must not exist in the destination directory in the local file system.
This procedure reads a local file or ASM and contacts a remote database to create a copy of the file in the remote file system. The directory object from which the file is copied at the local source site. The name of the file that is copied from the local file system.
This file must exist in the local file system in the directory associated with the source directory object. This directory object must exist in the remote file system. The name of the file placed in the remote file system. A file with the same name must not exist in the destination directory in the remote file system.

You should therefore be careful in copying or transferring a file that is being modified by the database because this can result in an inconsistent file, and require recovery. If you disable or do not configure this setting, virus security intelligence will be considered out of date after the default number of days have passed without an update.
This policy setting allows you to configure UNC file share sources for downloading security intelligence updates. Sources will be contacted in the order specified. The value of this setting should be entered as a pipe-separated string enumerating the security intelligence update sources. The list is empty by default. If you enable this setting, the specified sources will be contacted for security intelligence updates.
Once security intelligence updates have been successfully downloaded from one specified source, the remaining sources in the list will not be contacted. If you disable or do not configure this setting, the list will remain empty by default and no sources will be contacted. This policy setting allows you to configure the automatic scan which starts after a security intelligence update has occurred.
If you enable or do not configure this setting, a scan will start following a security intelligence update. This policy setting allows you to configure security intelligence updates when the computer is running on battery power.
If you enable or do not configure this setting, security intelligence updates will occur as usual regardless of power state. If you disable this setting, security intelligence updates will be turned off while the computer is running on battery power. This policy setting allows you to configure security intelligence updates on startup when there is no antimalware engine present.
If you enable or do not configure this setting, security intelligence updates will be initiated on startup when there is no antimalware engine present. If you disable this setting, security intelligence updates will not be initiated on startup when there is no antimalware engine present. This policy setting allows you to define the order in which different security intelligence update sources should be contacted.
The value of this setting should be entered as a pipe-separated string enumerating the security intelligence update sources in order. If you enable this setting, security intelligence update sources will be contacted in the order specified. If you disable or do not configure this setting, security intelligence update sources will be contacted in a default order. This policy setting allows you to enable download of security intelligence updates from Microsoft Update even if the Automatic Updates default server is configured to another download source such as Windows Update.
If you enable this setting, security intelligence updates will be downloaded from Microsoft Update. If you disable or do not configure this setting, security intelligence updates will be downloaded from the configured download source.
This policy setting allows you to enable real-time security intelligence updates in response to reports sent to Microsoft MAPS. If the service reports a file as an unknown and Microsoft MAPS finds that the latest security intelligence update has security intelligence for a threat involving that file, the service will receive all of the latest security intelligence for that threat immediately.
If you enable or do not configure this setting, real-time security intelligence updates will be enabled. This policy setting allows you to specify the day of the week on which to check for security intelligence updates. The check can also be configured to run every day or to never run at all.
If you enable this setting, the check for security intelligence updates will occur at the frequency specified. If you disable or do not configure this setting, the check for security intelligence updates will occur at a default frequency. This policy setting allows you to specify the time of day at which to check for security intelligence updates. By default this setting is configured to check for security intelligence updates 15 minutes before the scheduled scan time.
The schedule is based on local time on the computer where the check is occurring. If you enable this setting, the check for security intelligence updates will occur at the time of day specified. If you disable or do not configure this setting, the check for security intelligence updates will occur at the default time.
This policy setting allows you to define the security intelligence location for VDI-configured computers. If you disable or do not configure this setting, security intelligence will be referred from the default local source. This policy setting allows you to configure the antimalware service to receive notifications to disable individual security intelligence in response to reports it sends to Microsoft MAPS. Microsoft MAPS uses these notifications to disable security intelligence that are causing false positive reports.
If you enable this setting or do not configure, the antimalware service will receive notifications to disable security intelligence. If you disable this setting, the antimalware service will not receive notifications to disable security intelligence.
This policy setting allows you to define the number of days after which a catch-up security intelligence update will be required. By default, the value of this setting is 1 day.
If you enable this setting, a catch-up security intelligence update will occur after the specified number of days. If you disable or do not configure this setting, a catch-up security intelligence update will be required after the default number of days. This policy setting allows you to manage whether a check for new virus and spyware security intelligence will occur immediately after service startup. If you enable this setting, a check for new security intelligence will occur after service startup.
If you disable this setting or do not configure this setting, a check for new security intelligence will not occur after service startup.
Microsoft MAPS is the online community that helps you choose how to respond to potential threats. The community also helps stop the spread of new malicious software infections. You can choose to send basic or additional information about detected software. Additional information helps Microsoft create new security intelligence and help it to protect your computer. This information can include things like location of detected items on your computer if harmful software was removed. The information will be automatically collected and sent.
In some instances, personal information might unintentionally be sent to Microsoft. However, Microsoft will not use this information to identify you or contact you. Basic membership will send basic information to Microsoft about software that has been detected, including where the software came from, the actions that you apply or that are applied automatically, and whether the actions were successful.
Advanced membership, in addition to basic information, will send more information to Microsoft about malicious software, spyware, and potentially unwanted software, including the location of the software, file names, how the software operates, and how it has impacted your computer.
In Windows 10, Basic membership is no longer available, so setting the value to 1 or 2 enrolls the device into Advanced membership.
This policy setting customize which remediation action will be taken for each listed Threat ID when it is detected during a scan. Threats should be added under the Options for this setting. Each entry must be listed as a name value pair. The name defines a valid Threat ID, while the value contains the action ID for the remediation action that should be taken. This policy setting allows you to configure whether or not to display additional text to clients when they need to perform an action. The text displayed is a custom administrator-defined string.
For example, the phone number to call the company help desk. The client interface will only display a maximum of characters. Longer strings will be truncated before display. Use this policy setting to specify if you want Microsoft Defender Antivirus notifications to display on clients.
If you disable or do not configure this setting, Microsoft Defender Antivirus notifications will display on clients. NET Framework. Error calling Path.
