Policies

System administrators must establish effective data encryption policies. PK Protect policies, defined on this tab, are responsible for controlling the end user experience, configuring and locking program options and most importantly, specifying administrative policy keys for use by Audit, Discovery and Data Loss Prevention (DLP) people, processes and technology.

Each client device's agent application checks in with the PEM Administrator at a standard (configurable) interval. When the client checks in, PEM Administrator applies any policy changes. Policy order on the Policies page is important; the client agent processes the Policies list from the top down. The agent uses the first one that applies to its user. Each policy has a defined scope of users that it applies to. When group policies are applied to a client, those policies always override the site-wide policy. If no policy is defined for a particular user, they will receive the site-wide-default policy.

For example, let's say you want to define a policy that applies to your Admin group, composed of one person from each of your departmental groups (Sales, Executive, Marketing, IT). When you add a new policy, it assumes the top position. For the Admin group policy to be applied to those departmental representatives, you should define the departmental policies first. Otherwise, you can adjust the processing order by dragging policies Up or Down in the Order column. The Site-wide Default policy cannot be re-ordered.

User and Group Policies

Most policy controls will have four drop-down options:

Setting	Description
Allowed (default on)	Option is end user configurable and its default state is on
Allowed (default off)	Option is end user configurable and its default state is off
Required	Option is not end user configurable and has been locked on
Disabled	Option is not end user configurable and has been locked off

When creating a new policy, certain sections have default settings, which are listed in the table below:

Section	Control	Default Setting
Integration	Save changes as soon as possible	Allowed (default off)
Alternate Data Streams	Store Alternate Data Streams	Allowed (default off)
Encryption		Allowed (default on)

Defining a Policy

To define a policy, click Add button and following settings need to be configure.

General Settings

Following settings specify how often clients will connect with the PEM Administrator, for different purposes. The following options are available:

General configurations

Fields	Description
Name	The name of the policy (typically referring to the users or groups it will be assigned to). If you don't name the policy, PEM will describe the Policy with a date and timestamp. *Note: You cannot edit the name of Site-wide Default policy.
Authentication Check Interval (minutes)	This specifies in minutes, how often an agent re-authenticates with the PEM Administrator. By default, value is set to 15 minutes.
Offline File Format	PEM Agents cache encryption keys they have access to, for the system on which they run. If agent loses connection with PEM Administrator (or instance user’s AD account has been disabled and agent can no longer log in), the number in this field specifies the maximum time (in hours) the agent will keep keys before it automatically purges them from the device. By default, the value is set to 24 hours. *Note: Keys will be re-synched when device is successfully re-authenticated.
Mobile Format zip	The drop – down displays the file format that will be used when zip files are created on mobile. Zip and Zipx are the supported formats.
Allow Mobile App Access	This option enables or disables the ability to use PK Protect for iOS or Android platforms for specific set of users defined in policy. By default, this option is enabled.
Authority Information Access Certificate Chain Retrievals	By default, this option is enabled.
Reset Client Defaults	Enabling this option will reset settings in existing policy on any PK Protect client device before applying this new policy. It can be used in combination with mobile file format to set the client device to default settings to use the zipx file format instead of zip.
FIPS Mode	FIPS is an abbreviation for Federal Information Processing Standards, a set of standards for information processing in federal agencies in the United States. In FIPS 140 mode, encryption and decryption are done using only encryption and hashing algorithms that have been validated for compliance with FIPS 140-2 security requirements for cryptographic modules by NIST (National Institute of Standards and Technology), a branch of the US government. Click your preferred FIPS compliance options. Your selection will turn a bright blue; this is the default for clients that this policy applies to. The site-wide policy by default displays all the options, allowing clients to change from the default. To enforce just one selection (such as Use FIPS 140 Mode), delete the remaining options. Note: FIPS mode is not supported for MacOS X platform. The following FIPS settings are avaialable: Prefer fastest available algorithm* – This option uses the fastest version of Advanced Encryption Standard (AES) available on the system. By default, this option is selected. Prefer FIPS-Validated algorithm - Choose FIPS-validated algorithms over others if available but does not require FIPS algorithms to be used. Use FIPS 140 mode – This option will only use FIPS validated algorithms to encrypt or decrypt files, email messages and email attachments. Use FIPS- validated algorithm; allow AE extraction – This option will always choose FIPS validated algorithms to encrypt and decrypt data, but allows unzipping files encrypted with the AE-2 algorithm used by some compression applications.

Integration Settings

Following settings are available to configure the behavior of integrations with other applications:

Settings	Description
Auto Open single-document types	If a user receives a ZIP archive with a single file in it, often they want to open and read the zipped file without having to manually extract (decompress) it first. With the Integration settings, an admin can define a set of file extensions that will automatically open in native application.A default set of extensions, including Microsoft Office files, PDF, and graphics files.
Save changes as soon as possible	By default, when someone opens a single-file ZIP archive, the ZIP container stays open until the file is closed. If the user makes changes to the file, the archive container doesn't record the change until the file is closed and returns to the container. Use the drop-down menu to change the policy to allow users to edit documents and update the archive. If your policy allows this feature, client Office Integration settings will display this option; the user can turn this on or off. If your policy requires the feature, the setting will be checked; the user cannot change this. If your policy Disables the feature, the setting will not display in the client. *Note: if user continues making changes in the file while PK Protect is saving the previous changes, the data in the zip archive can get corrupted. It is always safer to enable the default behavior.
File Collaboration Options	This option allows user to set priorities when single-file ZIP archives are auto-opened and accessible to anyone. Collaboration Mode: Anyone can open and view a document inside a single-file ZIP, but only the first person to save a single-file archive is allowed to edit/change/save the source file. If others attempt to save changes, they are prompted to save a new ZIP, which can be merged into the original document later. Exclusive Mode: Only one user can open and edit a document inside a ZIP. Anyone else attempting to open and read the document in this file will get an announcement that the file is open. They may optionally ask to be notified when the archive is available. Collaboration and Exclusive Mode: If a file is auto-opened, Collaboration Mode applies. All other file types operate in Exclusive Mode. No Collaboration Mode: Anyone can open an archive and view its content. If a second person opens the file (in read-only mode), the first person cannot save changes to the archive. Note: If Save changes as soon as possible* and Collaboration Mode are both enabled, it's possible that two separate versions of the same document may exist. That is, User #1 opens DocumentX.docx, and while that document is being edited, User #2 opens DocumentX.docx, edits the same section. Both users save the document into a ZIP archive. User #3 might not know which wording is correct.
Enable Microsoft Word Plugin	If enabled, then this will show PK Protect menu item in the corresponding MS application.
Enable Microsoft Excel Plugin	If enabled, then this will show PK Protect menu item in the corresponding MS application.
Enable Microsoft Powerpoint Plugin	If enabled, then this will show PK Protect menu item in the corresponding MS application.

Users/Groups

The users and groups entered in this section are those to which the policy applies.

Settings

Description

Users/Groups

This field contains the list of Active Directory (AD) users and groups to which this policy should apply.

*Note: If a user is defined in more than one policy, the first one in the policy list will be applied.

Admins

This field contains the list of Active Directory (AD) users and groups that are allowed to control and modify this policy.

*Note: : If a user is defined who is not a Sys Admin, then this user will be added to the PEM Admins list and configured as a Security Admin.

Zip File Creation

To set encryption and signing policies for creating zip archives, configure the following sections:

Alternate Data Streams

A file is a stream of data stored on a hard drive. When you open a file, the stream takes up space in a computer's memory. On modern Windows computers, using the NTFS file system an individual files can contain multiple data streams. The content of a file is one data stream, but the same file can contain one or more alternate data streams. In the relatively rare instance, an alternate stream is created it usually contains additional information about a file.

For example, when Internet Explorer downloads a file from the Internet, it adds an alternate stream noting that the file originated outside the local network. PK Protect always retains this stream in archives. These streams are not common but can add size to a file.

Settings	Description
Store Alternate Data Streams	This will preserve the alternate data stream of a file during compression. By default, Allowed (default off) is selected.
Restore Alternate Data Streams	This will restore the alternate data stream of a file when extracting. By default, None is selected.

Encryption

Administrators can choose whether to require every zip archive to be encrypted, and whether to allow users to skip encrypting files on a case-by-case basis. By default, Allowed (default on) is selected.

Settings

Description

Algorithms

This field display the list of algorithms that can be used for encryption zip archive. PK Protect supports AES in several key lengths as well as AE2 (256-bit) and 3DES (168-bit).

By default, PK Protect uses the strongest available algorithm and key length (AES-256).

Passphrase

This setting allows you to control whether passphrase-based encryption is allowed. By default, Allowed (default on) is selected.

Smartkeys

By default, Allowed (default on) is selected. In addition to the basic usage settings, the following options are available when Smartkeys are allowed:

Settings	Description
Allow users to create Smartkeys	Users can create and define recipients of Smartkeys. By default, this option is enabled.
Allow users to delete Smartkeys	Users can delete Smartkeys which they have created. By default, this option is disabled.
Allow encryptions with user's private Smartkey	Users can encrypt data with a private Smartkey issued with an account. By default, this option is enabled. *Note: Files encrypted with private Smartkeys cannot be decrypted by contingency keys or contingency group members.
Allow encryption using Smartkeys owned by other individuals (besides community keys)	Users can encrypt data with a Smartkey owned by another user. By default, this option is enabled. *Note: Another User may be a PK Protect user outside of your organization.
Allow users to copy Smartkey passphrase	Smartkeys automatically contain a passphrase. By default, this option is enabled. If users share Smartkey-encrypted files with non-PK Protect users, this option allows those users to access the Smartkey passphrase and allow the recipient to open the encrypted file.

Certificates

By default, Allowed (default on) is selected. If you allow users to employ Public Key Encryption in addition to Smartkeys, check the appropriate settings to configuration these options:

Settings	Description
Allow X.509 certificates	Users can encrypt the data using X.509 personal certificates.
Allow OpenPGP Keys	Users can encrypt the data with the help of OpenPGP keys.
Perform Strict Checking	Strict checking identifies certificates that are valid and designated for encryption. Following options are enabled when you select this option: Check Key Usage - Check the purpose for which the certificate is designated (encryption or signing). Check time validity - Check whether the current date is within the valid range of dates for the certificate. Check time nesting - Check whether the period of validity of the certificate does not extend past the dates when the issuer certificate is valid. For example, if the issuer certificate is valid from February 1, 2015, to January 31, 2018, the date range during which the selected certificate is supposed to be valid does not begin before February 1, 2015, or end after January 31, 2018.
Filter Issue (CN)	If you wish to see only those certificates which are created by a specific certificate authority, type the issuer's name in this field. This information can be found in the Details tab of Certificate Properties. Look for the Issued by section in the Details tab, and type everything after CN=in the field For example, if all your company's certificates are issued by COMODO, type (no quotes) "COMODO Client Authentication and Secure Email CA" in the field.
Filter Issue (OU)	If you wish to see only those certificates which are issued to someone in a specific organization, type the complete Organizational Unit (OU) name in this field. This information can be found in the Details tab of Certificate Properties. Look for the Issued to section in the Details tab, and type everything after OU= in the field. For example, if all your company's certificates have an OU of Corporate Secure Email, type (no quotes) "Corporate Secure Email" in the field.
Check certificate revocation	This option causes PK Protect to warn if a selected certificate’s signature appears on an accessible list of certificates that have been revoked. When Strict Checking option is turned on, PK Protect does not use a revoked certificate. To use this option, you must download a list of revoked certificates from a certificate authority.

Signing

By default, Allowed (default on) is selected in the drop-down. Following settings need to Configure:

Settings	Description
Signature Algorithm	The signature algorithm creates a hash value for the file to be signed. The hash value uniquely represents the file: any change to the file gives it a different hash value. Comparing the hash value of the file when it was signed with the file's current hash value reveals whether the file has been changed. PK Protect uses the SHA2 hash algorithm at 256-bit strength by default. Stronger versions (384- and 512-bit) of SHA2 are also available. Click the button to approve the use of either of these algorithms. *Note: You may allow the use of the MD5 or SHA1 algorithms by clicking in a blank space on this line. These algorithms are deprecated for signing keys, and not recommended.
Perform Strict checking	Strict checking identifies certificates that are valid and designated for encryption. To learn more, refer to Perform Strict Checking.
Filter Issue (CN)	If you wish to see only those certificates which are created by a specific certificate authority, type the complete issuer's name in this field. This information can be found in the Details tab of Certificate Properties. Look for the Issued by section in the Details tab, and type everyting after CN= in the field. For example, if all your company's certificates are issued by COMODO, type (no quotes) "COMODO Client Authentication and Secure Email CA" in the field.
Filter Issue (OU)	If you wish to see only those certificates which are issued to someone in a specific organization, type the complete Organizational Unit (OU) name in this field. This information can be found in the Details tab of Certificate Properties. Look for the Issued to section in the Details tab, and type everything after OU= in the field. For example, if all your company's certificates have an OU of Corporate Secure Email, type (no quotes) "Corporate Secure Email" in the field.
Check certificate revocation	This option causes PK Protect to warn if a selected certificate’s signature appears on an accessible list of certificates that have been revoked. When Strict Checking option is turned on, PK Protect does not use a revoked certificate. To use this option, you must download a list of revoked certificates from a certificate authority.
Check certificates revocation when verifying	This option allows you to check whether an X.509 certificate has been revoked that has been used to sign or encrypt any file in the archive or the archive itself.
Allow Archive Spitting	Enabling this option gives users the ability to take a zip file and spilt it into many zip files which together make the original zip file.

OpenPGP File Creation

If you want to allow client to create OpenPGP files, check Allow OpenPGP File Creation checkbox. Following settings appear:

Settings	Description
ASCII Armor	ASCII Armor (also known as Radix-64) is a character format that creates an ASCII character stream that could be used in transferring OpenPGP files through transport mechanisms that can only handle character data (for example, email body text). By default, Allowed (default on) option is selected.
Encryption	This option allows users to create OpenPGP files and disable encryption. By default, Allowed (default on) option is selected.
Algorithm	PK Protect offers the choice of the algorithms shown below. Different key lengths are supported for the Advanced Encryption Standard (AES) algorithm. In general, the longer the key, the stronger the encryption. Encryption also takes slightly longer in proportion to the length of the key. AES – This is standard algorithm adopted by US federal government and in widespread used in banking and credit card operations. CAST5 – This algorithm is the default algorithm for OpenPGP clients. IDEA – This is an optional algorithm in the OpenPGP standard, used in many OpenPGP clients.
Passphrase	By default, Allowed (default on) option is selected.
OpenPGP Key	By default, Allowed (default on) option is selected. This allows OpenPGP keys to be used
Sign Files	By default, Allowed (default on) option is selected.
Algorithm	By default, Pk Protect uses SHA2 Hash algorithms at 256-bit strength. Stronger versions, SHA2 (384-bit) and SHA2 (512-bit) are also available to be used for encryption. *Note: You can allow the use of MD5 or SHA1 algorithms by clicking in a blank space on this line. However, these algorithms are deprecated for signing keys, and are not recommended.

Passphrase Complexity

To secure passphrase-encrypted files, use passphrases that are long enough, and which are not easy to guess. An administrator can set requirements for both minimum and maximum passphrase lengths. To enable password complexity s, Check Enforce passphrase complexity rules checkbox.

For example, you can require a minimum passphrase length of 15 characters, or even 260 characters, instead of the default minimum of eight. Whenever user encrypts with a passphrase, PK Protect enforces the rules by rejecting any proposed passphrase that does not comply. Following settings are available:

Settings	Description
Minimum Length	The minimum number of characters that a passphrase must contain. Passphrases shorter than this are rejected. You can require a minimum length as large as 260 characters. By default, the length of passphrase is 8 characters.
Maximum Length	The maximum number of characters that a passphrase can contain. Passphrases longer than this are rejected. By default, the maximum length of passphrase is 250 characters. You can assign 260 characters as a maximum length.
Maximum Repeats	Sets the maximum number of adjacent, case-sensitive occurrences of the same character. A setting of 1 allows no repetitions. A setting of 2 allows two adjacent occurrences, and so on. A setting of 0 (the default) turns the option off and allows all repetitions. For example, a setting of 2 disallows a passphrase that contains aaa but allows aAa or a1a2a.
Minimum Lowercase	The minimum number of lower-case alphabetical characters a passphrase requires. The default value is set to 0 (zero).
Minimum Uppercase	The minimum number of upper-case alphabetical characters a passphrase requires. The default value is set to 0 (zero).
Minimum Digits	The minimum number of digits i.e., 0-9, a passphrase requires. By default, the value is set to 0 (zero).
Minimum Symbols	The minimum number of special characters a passphrase requires. By default, a special character is defined as a non-alphanumeric character. The default value is set to 0 (zero). E.g., @, #, $, %,',’, , (,), ,_,-,+,=,{,},&,&,:, ;,<,>,/,\,`,~,!,",,^,[,].

Contingency

Choose from a list of existing contingency keys associated with this installation. To define a contingency key, return to the Policies page and click Add New Contingency Key in Contingency Public Keys (X509/OpenPGP) panel. To learn more, refer to Contingency Public Keys (X509/OpenPGP). This feature is used by companies to ensure that they never experience a situation where a user can encrypt a file, and once they leave organization and there is no one who can decrypt it.

Settings	Description
Contingency Keys	This field allows you to specify the contingency keys that can be used for the decryption of files.
Enable Contingency Users	Enabling this option allows you to specify the contingency users.
Contingency Users	This field allows specific individuals to be defined, who will be able to decrypt information encrypted by the users in this policy. To enable this feature, select the Enable Contingency Users checkbox. If enabled, then this feature will allow selected users to decrypt any files encrypted with any key. If disabled, this feature will disable the contingency public key but will not delete it. After disabling, the members of the policy will not be able to decrypt previously encrypted file, nor they will be able to decrypt newly encrypted file.

Email Settings

The PK Protect application on Windows has a plugin that can run to control encryption operations emails in Outlook. Check Enforce Outlook Integration checkbox to configure email settings in a policy. Following is the settings:

We can leave the existing documentation the way it is, for this section. We are currently replacing it with the new email page, and don’t need to spend time updating documentation for functionality that’s going to be replaced.

Plugin Actions

This allows control on the default and available actions from the PK Protect Outlook Plugin. The default option displays in bright blue, Other allowed actions are displayed in a grayer blue; and admins can prevent certain functionality by not including them in the field. Following actions are taken on emails:

Encrypt message body and attachment – Select this option to allow users to send an email i.e., an encrypted email body. The subject line does not get encrypted into the .zip archive. The recipient can use email mime (.eml) viewer to read the original message. This is the most secure option, but also the most obtrusive to normal email workflow.
Encrypts attachment only - Include this option to allows users to send an email and ignore the body of the email message, and it only encrypt the attachments to the email. The attachments will be gathered and included in single zip archive and then gets encrypted.
Compress attachment only - Include this option to allows users to send an email and ignore the body of the email message, and it only compress the attachments to the email. The attachments will be gathered and included in single zip archive and then compress, but not encrypted.
Skip actions - Include this option to allows users to send an email that bypasses the PK Protect Outlook Plugin. Do not select this option if desired bypass is not required.

Extensions to Include

This field displays the list of file extensions that will be considered by PK Protect Plugin when performing ‘Compress Attachments Only’ and ‘Encrypt Attachments only’. E.g., If the policy is set to exclude ‘.pdf’ extensions and user performs an action by sending an email with PDF attachment. Following action is taken:

PK Protect Outlook Option Selected	Action	Description
Encrypt Message Body and Attachment	Email body and all attachments are encrypted.	Since this outlook option encrypts the body and attachments, the extension filters are ignored, and the body and attachments are encrypted.
Encrypts Attachments only	PDF file is added to encrypted archive.	If there is a match on extension, the attachment is encrypted.
Compress Attachments only	PDF file is added to encrypted archive.	If there is a match on extension, the attachment is compressed.

If user sends a ‘.png’ attachment instead of ‘.pdf’ then in that case following actions are taken:

Auto-Search Recipients	Auto-Search Recipients will look at the Smartkeys that all recipients have access. If a Smartkey is not found, a new key can be created with all recipients included on the email message. By default, the Allowed (default on) option is selected.
Include Unzip Instructions	PK Protect can include a plain text (non-encrypted) document with instructions on how to decrypt the attachment. Default: Allowed (default on).
Instructions	Text added here will be provided in a text file that is sent out automatically when a user sends an encrypted attachment. This text can be plaintext or HTML formatted. *Note: This is not used when email body encryption is activated or when discovery filter override recipient filtering is not checked.

Re-Encrypt Attachments	Users can change the encryption on existing zip archives attached to an email message. This option must be set if you want PK Protect to encrypt existing archives. By default, the Allowed (default on) is selected.
Default Zip Name	Using this option, you can give same generic name to all ZIP file attachments that contain multiple files. You can also define alternate three-character extension of the zip archives. Some networks have security settings that prevent file attachments with the zip extension from being sent or received. Use this feature if this is an issue for you and your recipients. When you zip a single attached file, ordinarily the ZIP file is named after the attached file itself. If the security option to encrypt file names is set, the generic name is always used. For example, if the attached file is employee_data.docx, PK Protect names the zip file employee_data.zip. *Note: This field accommodates for a .zipx entry, as an alternative to zip.
Enable Recent Mode	If this option is checked, users can select ‘Recents’ from PKWARE tray icon in the Windows operating system. It displays the list of all messages that have been recently sent.

Contingency Public Keys (X509/OpenPGP)

Contingency keys enable an organization to decrypt files encrypted by anyone in the organization, whether the files were passphrase-encrypted or were encrypted for specific recipients.

Contingency keys are third-party OpenPGP or X.509 formatted public keys that will be automatically included in every encryption operation performed by PK Protect. These keys are generated outside of the PK Protect ecosystem in accordance with organization's security policy. Whether the files are password-encrypted or encrypted for specific recipient public keys, contingency keys provide a safeguard to be sure that important information belonging to the organization does not become inaccessible because no one in the organization can decrypt it. Contingency keys must use RSA-2048 (or stronger) encryption.

*Note: When you need to open a file encrypted with a contingency key, be sure the private key is accessible.

Adding Contingency Keys

To add a contingency key to PEM Administrator for use in a Policy, follow the below steps:

Click Addbutton in the Contingency Public Keys (X509/OpenPGP) panel. This opens New Contingency Key
Browse system for the public key file by clicking Choose File
Click Upload to upload the key to PEM.
