How to setup and run data loss prevention (DLP) scans in Endpoint Manager

Click 'Configuration Templates' > 'Data Loss Prevention'

• Data loss prevention (DLP) rules let you scan Windows devices for files that contain sensitive information.
   
• For example, the scan finds card numbers, social security numbers, bank account numbers, bank routing numbers, and more.
   
• There are two types of DLP rules:
   
• Discovery rules - Define the areas you want to scan, the type of information you want to search for, and the action you want to take on discovered files.
   
  • Discovery rules are added to profiles, which are in turn applied to managed devices. You also have the option to run on-demand discovery scans on devices.
     
  • You can review all files which contain sensitive data from the Endpoint Manager interface. You can then take actions to secure that data where required.
     
• Monitoring rules – Block users from copying files to external storage devices.
   
  • EM monitors attempted data transfers to devices like USB drives and allows/blocks the transfer in real time.
     
  • Monitoring rules are added to profiles which are in-turn applied to managed devices for continuous monitoring.

Overview

•   You first create a discovery scan rule at ‘Configuration Templates' > 'Data Loss Prevention' > 'Create Discovery'.  
   
•   You then add the scan to the DLP section of a profile. The scan will run on all devices on which the profile is active.
   
•   You can view scan results at 'Security Subsystems' > 'Data Loss Prevention' > 'Logs'.
   
•   You can also manually run discovery scans on devices at ‘Security Sub-systems’ > ‘Data Loss Prevention’ >  'Device List'

Create a DLP scan rule

• Click 'Configuration Templates' > 'Data Loss Prevention' >  'Create Discovery'

Scan rules tell the DLP scan exactly what type of data to search for. You will define the following items:

• Location - The folders or drives that you want to scan on target devices. For example, 'C:\Users\'.
   
• File types - The file extensions you want to inspect. For example, .doc, .xls, .txt.
   
• Search pattern - The type of data you want to search for. For example, card numbers, bank account numbers, social security numbers, dates-of-birth, etc.
   
• Action - The response Endpoint Manager should take when the rule conditions are met. The options are ‘ignore’ and ‘quarantine’.

You add the scan rule to a profile, which is in turn applied to target devices or users.

• Click 'Configuration Templates' > 'Data Loss Prevention'
   
• You can see the DLP rule with validity status here whether it is valid or invalid to use. If a rule does not have any of the following criteria, 'Targets',’ Exclusions’,’ Patterns’,’ Documents Types’ and ‘Profiles’ are empty the rule should be invalid, you cannot get expected results in scanning
  
  
  
   
• To create a ‘Discovery Rule’, Click 'Create' > 'Discovery Rule'
   

Complete the following fields:

Name - Enter a label for the rule

Description – Add a short note for your reference

Action - The response Endpoint Manager should take on files which meet the rule conditions. The options are:

•   Ignore – Take no action on the file. You can still review the files at ‘Security Sub-systems’ > ‘Data Loss Prevention’ > ‘Logs’.
   
•   Quarantine – The file is moved from its original location on the endpoint and placed in a secure holding area. Users cannot open quarantined files. You can review quarantined files as follows:
   
  •    Local Endpoint - Open Comodo Client Security > Click ‘Tasks’ > ‘DLP Tasks’ > ‘Data Loss Prevention Quarantine’. You can restore the files to the original location from here if required.
     
  •  Endpoint Manager - Click ‘Security Sub-Systems’ > ‘Data Loss Prevention’ > ‘Quarantined Files’. You can restore the files to original location or delete the files on the local endpoint.

Show match results with first and last symbols in View Logs - If enabled, the log details of a file intercepted by the rule shows the actual data discovered in the file. Only the first and last characters of the record are shown. For example, a ten digit social security number would be shown as 3 - - - - - - - 9. See View scan results for more on the viewing logs and details of files that created a DLP event.

  • See this wiki if you need help to create and manage file groups.
     
• Repeat the process to add more exclusions.

 

Patterns

The patterns tab is where you tell the scan what types of data you want to search for.

•  A 'pattern' is the format used by the type of data you want to find. Each pattern is a combination of a keyword group and information format.
   
• For example, the ‘Name with SSN’ pattern consists of:
   
  • Keyword group = ‘Names’ group.
     
  • Information format =  9 digit number arranged in 3-2-4 formation, like '123-45-6789'.
     
• EM ships with a number of patterns which you can use to search for sensitive data.
   
• You can also create custom patterns as combinations of information formats and keyword groups. See Manage data patterns if you need help with creating custom patterns.

Add patterns

• Click the 'Patterns' tab then 'Edit'
   
• Click 'Add Pattern'

 

• Pattern - Choose the type of information that you want to search for in scanned locations.
   
  • The drop-down shows the pre-defined patterns shipped with EM and the custom patterns added by you. For example, credit card numbers, social security numbers, bank routing numbers, etc.
     
  • Each pattern can contain a single data format or can be a combination of specific data format(s) and keyword(s) or keyword group(s)
     
  •  You can view, create and manage available patterns in the 'Settings' >  'Data Protection Templates' > 'Patterns' interface.
     
  • See Manage data patterns if you need help with this.
     
  • You can customize the selected pattern to narrow down the search only for data containing specific values in certain fields. For example, only search for data containing names and 10 digit bank account number, starting with '4687'.

• Threshold - The number of times that data matching the pattern must be found in a document. Endpoint Manager will flag a document if it contains the threshold quantity of pattern examples.

 

Once you select a pattern the components of the pattern are shown:
 

Narrow down the search (optional):

You can customize the pattern to search only for data containing specified values in certain positions in the sequence. This is optional.

The left pane shows the components in the pattern and the right pane shows an expanded view of the component chosen in left pane.

• Click a component to expand it on the right pane
   
  • For keyword group, the right pane lets you select a keyword group
     
  • For data format (Custom Mask), the right pane shows the arrangement of characters in it.

                   A = any character / symbol

                   D = number

                   L = alphabetical letter

                   S = Special symbol

 

• Select 'Allow to specify Mask'
   
• Enter the specific/constant characters for which you want to limit your search, in the text fields of the respective positions
   
• Click 'Set Mask Configuration'
   
• Click 'OK'

Note - You cannot specify mask characters for pre-defined-standard information types like credit card numbers and social security number that ship with EM. If you want to use mask characters for any of those data, create a similar custom information type with a different name, add it to a custom pattern and use the custom pattern in the rule. See Manage data patterns to know more about adding custom information types to a pattern.

Illustration:

For example, you add 'Name with 10 digit account number' as search pattern but want to narrow down the search to only identify account numbers starting from '1234'.

• Choose 'Name with 10 Digit Account Number' as your pattern

• Click 'Custom Mask' to expand it on the right pane
   
• Select 'Allow to specify Mask'
   
• Enter '1', '2', '3' and '4' in the first four text fields

The values are automatically added to their positions in the data type.

 

• Click 'Set Mask Configuration'
   
• Click 'Ok'

Repeat the process to add more patterns.

 

• Click the pencil icon on the left if you want to edit a pattern
   
• Click 'Save'.

Note – You MUST add keywords to the keyword group used in a pattern, or the search will not work. For example, you must add some names to the ‘Names’ group.

• See Add keywords to keyword groups for help with this.

Document types

• This tab lets you choose which types of file you want to scan for sensitive data.
   
• You can choose PDFs, Word documents, HTML files, text files and/or ZIP files.
   
• The scan will search the content of all files which have a matching file extension in the locations you specified.

Click the 'Document Types' tab then 'Edit':

 

• Use the switches in the status column to choose which types of files you want to scan.
   
• Click 'Save'

• Repeat the process to add more rules.

You can now add the rule to a profile. If your pattern contains the ‘Name’ group, please make sure you have added keywords to the group. 

Manage data patterns

You can view,create and manage available patterns in 'Settings' > 'Data Protection Templates' > 'Patterns'

• Patterns are used by DLP scans to identify sensitive data.
   
• A pattern can just be an ‘information format’ or be a combination of an ‘information format’ and keywords.
   
  • An information format is the notation used by the type of data you want to find. For example, the information format of an SSN is a nine digit number in 3-2-4 formation, like '123-45-6789'.
     
  • Keywords can be indivudual keywords or keyword groups. Each keyword group can contain a set of keywords that belong to a category, like names and network terms
     
• EM ships with a set of pre-defined patterns
   
• You can also create custom patterns to define custom information formats

View data patterns

• Click 'Settings' > 'Data Protection Templates'
   
• Click the 'Patterns' tab

The pattern variables interface shows a list of pre-defined and custom patterns and lets you create new patterns:

The following table shows the information formats and keyword groups contained in each predefined  pattern:
 

Pattern	Description
Turkish Nationality ID Number	Consists of citizen number in Turkey
Name with 5-8 Digit Account Number	Consists of Keyword Group 'Names' and a bank account number
Name with 9 Digit Account Number	Consists of Keyword Group 'Names' and 9 digit bank account number
Name with 10 Digit Account Number	Consists of Keyword Group 'Names' and 10 digit bank account number
Name with SSN	Consists of Social Security Number and Keyword Group 'Names'
ABA Routing number	Consists of American Bankers Association (ABA) routing number. This is the nine digit bank code printed in negotiable instruments in the US.
Date of birth	Consists of Birth Date
Credit Card Number	Consists of Credit Card Number
IP Network	Consists of IPv4 and IPv6 IP Addresses  Examples:  192.0.2.0/24  198.51.100.0  2001:0db8:85a3:0000:0000:8a2e:0370:7334  2001:db8:1234::/48
Network Address	Consists of URLs, and domain names  Examples:  http://domain.name  https://domain.name  www.domain.name  domain.com  local.net
IBAN Code	Bank account number in International Bank Account Number (IBAN) format.
MAC Address	Searches for mac addresses, the unique identifier assigned to network cards.

 

Create a custom pattern

• Click 'Settings' > 'Data Protection Templates'
   
• Click the 'Patterns' tab
   
• Click 'Create Pattern'

 

• Enter a label for the pattern and click 'Create'
   

 

• Click the 'Pattern Elements' tab
   
• Click 'Add Element' and choose a component information type or keyword group to add to the pattern:

 

Keyword	Specify a single keyword as a component of the pattern
Keyword Groups	Add a keyword group to the pattern. You can manage term in a keyword group in 'Settings' > 'Data Protection Templates' > 'Static Keyword' interface. See Add keywords to keyword groups if you need help with this.
Custom Mask	Specify a custom information type. You can define a sequence of different character types like alphabets, numerals and special characters in the order they appear in the data you want to search.   Use: 'A' in place of any character 'D' in place of a numeral 'L' in place of an alphabet letter 'S' in place of a special character For example, to define a 7 character vehicle license plate number, you can specify:                                                          'DLLLDDD' Match All – Enabled – Only the data that match fully with the information type are identified by the rule in which the pattern is used   Disabled – Data that match partially  with the information type are identified by the rule in which the pattern is used You can narrow down the scope of search by specifying constant characters in place of variables, while adding the pattern to a discovery rule. See Patterns for more details.
ABA Routing Number                        Date of Birth SSN Mac Address IP Network Address Network Address         IBAN Bode Credit Card Number Turkish Nationality ID Number	Predefined - standard information types.

 

• Repeat the process to add more elements to the pattern

Edit or delete a pattern

• Click 'Settings' > 'Data Protection Templates'
   
• Click the 'Patterns' tab
   
• Click a custom pattern to edit it.
   
• The process of editing is similar to adding a pattern
   
• Select a pattern and click 'Delete Pattern(s)' to remove it.
   
• Note – You can edit or delete only custom pattern. Pre-defined patterns cannot be edited or deleted.

Add keywords to keyword groups

Click 'Settings' > 'Data Protection Templates' > 'Static Keywords'

• Keyword groups are used by DLP scans to identify sensitive data. Each group is a list of specific items which the scan will search for.
   
• For example, the ‘Names’ group should contain the surnames of the employees/users in your protected network.
   
• The keyword group is paired with an ‘information format’ to form a 'pattern'.
   
  • An information format is a notation used by the type of data you want to find. For example, the information format of an SSN is a nine-digit number in 3-2-4 formation, like '123-45-6789'.
     
  • So a search for the SSN ‘pattern’ will identify all instances of ‘Name + SSN’ in target documents.
     
• You MUST add some names to the ‘Names’ group or the search will not work. Patterns that have an empty keyword group will not produce any results.

Add names to the ‘Names’ keyword group

• Click 'Settings' > 'Data Protection Templates'
   
• Click the 'Static Keywords' tab
   
• Click '+' at the left of a group name

There are two ways you can add keywords:

1    Type them in the field provided. Click ‘Add’ after each keyword.
 

 

• Repeat the process to add more keywords

2    Import them from .csv file. Click the import icon on the right then browse to your .csv file:
 

 

Advice: The scan searches for an exact match on the keywords you add.   Because of this, we advise you add only surnames to the ‘Names’ group at first. This will detect the most variants of the subject’s name.   For example, the keyword ‘Bowman’ will catch the following variants in an SSN pattern search: Robert T Bowman 123-45-6789 Rob Bowman 123-45-6789 Robert Bowman 123-45-6789 R. Bowman 123-45-6789 Bowman Robert 123-45-6789 etc.
