Exclusions

Enterprise Inspector provides the ability to match incoming events against rules. Rules are defined using an xml-based language able to predicate condition over events property (such as module name, hash, signer, popularity).

Rules can be edited/enabled/disabled in the UI and upon events reception are provided to the RuleEngine component to be compiled and matched against the events, eventually raising an detection.

This way, you can describe and identify problematic events in the agent's network.

Unlike Endpoint Protection, EEI is targeted to security analysts. Therefore, false positives are tolerable; though on a big network the number of detections raised by some rules can be overwhelming.

For this reason, the possibility to filter/exclude some detections is needed.

As most of the filtering is going to be based on exactly the same property used in the rules, exclusions are defined using the same language used by the rules. This has the notable advantage of allowing for fair reuse of much of the existing machinery.

Unlike rules, users does not have to edit exclusions manually, but this guide provides an editing tool/wizard, as exclusions are usually strictly related to some existing rule. This wizard, starting from an existing detection, will provide some initial values for the exclusion rule conditions.

ESET is providing a set of predefined exclusions, which are disabled by default and user can enable them as he wish.

 

Right-click exclusion name or left click anywhere else on the row to bring up a context menu with the following options:

Edit—redirect to exclusion edit tab. It is the same like Create rule exclusion, but with Update exclusion heading

Edit (New Tab)—redirect to exclusion edit in a new tab. It is the same like Create rule exclusion, but with Update exclusion heading

Enable—enables the exclusion

Disable—disables the exclusion

Delete—deletes the exclusion

Display Absolute/Relative Time—Absolute time will show the time in format DD/MM/YYYY HH:MM:SS. Relative time will show the time in the format minutes/hours/months in relation to present time, like "15 minutes ago" or "6 days ago"

Filter—you can find these quick filters, depending on the column:

oShow only this—Shows only records, based on this particular value

oHide this—Hides all records based on this particular value

oShow before—shows only records that are before this value (for example, time)

oShow after—shows only records that are after this value (for example, time)

oShow lower—Shows only records, which value is lower than this particular one

oShow higher—Shows only records, which value is higher than this particular one

Tags

Tagging is an additional form of filtering that can connect multiple objects through multiple views (computer, executable, event filter, etc.). If available, the tag icon Tag_Panel is on the left side, next to the name of the view. In the Computers view, the tag panel can be accessed by clicking the Three_dots icon. In the opened tag panel, all created tags are listed and ready to use. If the list of tags is already too long, you can use the magnifying glass to search for a specific tag. At the top of the screen, the TAGS selector can be used to select the desired tags. If available, the user can use also TAGS button located at the bottom of the screen among action buttons.

Additional filters

The additional filters are accessible by clicking the ADD FILTER button or clicking on a space next to the add filter button, where the list of available filters shows. The user can search filter by typing its name or selecting from the list. For the definitions of the additional filters, follow here.

Some of the filters have a funnel icon next to them with two or four possible predefined options:

Unknown—the value in the filtered column is not available (probably not a known value at the time of occurrence)

Known—the value is available

None—value is an empty string

Any—the value is not empty. The negation of None filter

If present on the screen you, can refresh the table by clicking the refresh iconAlarms_Refresh. If available, the export icon Export_CSV can be used to export the table grid to CSV format and use it in other applications to work with the list.

If present, click the PRESETS button to manage filter sets. These options are available:

Save filters—allows you to save the actual filter set. Select the check box Include the visible columns and sorting to save also this setting of your selection, otherwise when loading saved filter without this option selected will end up by showing you the default column setting

Reset filters—resets active filter and return to default filter setting with default column setting

Reset view—resets the active view without resetting the filter set

Manage—allows you to manage your filter sets

Save Filters as Rule—if available, allows you to save the filter as a rule. You can find it then in the list of rules under the Detection rules sub-tab of the admin tab

Columns

Columns can be reorganized by using the Columns_Move icon that appears on the right side of the column name when you hover the mouse over the column name.

The width of the column can be re-sized by the Column_Resize icon that appears on the left side of the column name when you hover the mouse over the column name.

The order of the columns can be organized by clicking the name of the column:

Default (No icon)

Ascending Column_Ascending

Descending Column_Descending

You can change which columns are displayed after clicking the gear icon and selecting the Select column option, or you can reset the view to default by clicking the Reset columns option. You can use Enter quick search pattern—here, you can search for the column by typing its name or a couple of letters from it. Useful if the list of columns is long. For the definitions of the columns follow here.

You can select all exclusions by selecting the check box on the left side of the Name column header, or you can select each exclusion individually by clicking its corresponding check box.
