Table 4. Certificate Authority
System Property Description
edge.certificate.renewal.window This optional system property allows the Operator to define one or more maintenance windows during which the Edge certificate renewal is enabled. Certificates scheduled for renewal outside of the windows will be deferred until the current time falls within one of the enabled windows.

Enable System Property:

To enable this system property, type "true" for "enabled" in the first part of the Value text area in the Modify System Property dialog box. An example of the first part of this system property when it is enabled is shown below.

Operators can define multiple windows to restrict the days and hours of the day during which Edge renewals are enabled. Each window can be defined by a day, or a list of days (separated by a comma), and a start and end time. Start and end times can be specified relative to an Edge's local time zone, or relative to UTC. See image below for an example.

edge.certificate.renewal.window system property. Select True to enable.

Note: If attributes are not present, the default is enabled "false."
When defining window attributes, adhere to the following:
  • Use IANA time zones, not PDT or PST (e.g. America/Los_Angeles) See https://en.wikipedia.org/wiki/List_of_tz_database_time_zones for more information.
  • Use UTC for days (e.g. SAT, SUN).
    • Separated by comma.
    • Days in three letters in English.
    • Not case sensitive.
  • Use Military 24 hour time format only (HH:MM) for start times (e.g. 01:30) and end times (e.g. 05:30).

If the above-mentioned values are missing, the attribute defaults in each window definition are as follow:

  • If enabled is missing, the default value = false.
  • If timezone is missing, the default = 'local.'
  • If one of either 'days' or end and start times are missing, the defaults are as follows:
    • If 'days' is missing, the start/end is applied to each day of the week (Mon, Tue, Wed, Thur, Fri, Sat, Sun).
    • If end and start times are missing, then any time in the specified day will match (start = 00:00 and end = 23:59 ).
    • NOTE: One of either 'days' or end and start times must be present. However, if they are missing, the defaults will be as indicated above.

Deactivate System Property:

This system property is deactivated by default, which means the certificate will automatically renew after it expires.

Table 15. Password Reset and Lockout
System Property Description
vco.enterprise.resetPassword.token.expirySeconds Duration of time, after which the password reset link for an enterprise user expires.
vco.enterprise.authentication.passwordPolicy

Defines the password strength, history, and expiration policy for customer users.

Edit the JSON template in the Value field to define the following:

strength

  • minlength: Minimum password character length. The default minimum password length is 8 characters.
  • maxlength: Maximum password character length. The default maximum password length is 32 characters.
  • requireNumber: The password must contain at least one numeric character. Numeric requirement is enabled by default.
  • requireLower: The password must contain at least one lowercase character. Lowercase requirement is enabled by default.
  • requireUpper: The password must contain at least one uppercase character. Uppercase requirement is not enabled by default.
  • requireSpecial: The password must contain at least one special character (for example, _@!). The special character requirement is not enabled by default.
  • excludeTop: Password must not match a list of the most used passwords. Default value is 1000, representing the top 1000 most used passwords, and is configurable to a maximum of 10,000 of the most used passwords.
  • maxRepeatingCharacters: Password must not include a configurable number of repeated characters. For example, if maxRepeatingCharacters is set to ‘2’ then the Orchestrator would reject any password with 3 or more repetitive characters, like “Passwordaaa”. The default value of -1 signifies that this feature is not enabled.
  • maxSequenceCharacters: Password must not include a configurable number of sequential characters. For example, if maxSequenceCharacters is set to ‘3’ then the Orchestrator would reject any password where 4 or more characters which are sequential, like “Password1234”. The default value of -1 signifies that this feature is not enabled.
  • disallowUsernameCharacters: Password must not match a configurable portion of the user's ID. For example, if disallowUsernameCharacters is set to 5, if a user with username [email protected] attempts to configure a new password that includes ‘usern’ or ‘serna’, or any five-character string that matches a section of the user’s username, that new password would be rejected by the Orchestrator. The default value of -1 signifies that this feature is not enabled.
  • variationValidationCharacters: New password must vary from the old password by a configurable number of characters. The Orchestrator uses the Levenshtein distance between two words to determine the variation between the new and old password. The Levenshtein distance is the minimum number of single-character edits (insertions, deletions, or substitutions) required to change one word into another. 
  • If variationValidationCharacters is set to 4, then the Levenshtein distance between the new and old password must be 4 or greater. In other words, the new password must have 4 or more variations from the old password. For example, if the old password used was "kitten" and the new password is "sitting", the Levenshtein distance for these is 3, since it requires only three edits to change kitten into sitting:
    • kitten → sitten (substitution of "s" for "k")
    • sitten → sittin (substitution of "i" for "e")
    • sittin → sitting (insertion of "g" at the end).

Since the new password only varies by 3 characters from the old, “sitting” would be rejected as a new password to replace “kitten”. The default value of -1 signifies that this feature is not enabled.

expiry:
  • enable: Set this to true to enable automatic expiry of customer user passwords.
  • days: Enter the number of days that an customer password may be used before forced expiration.
history:
  • enable: Set this to true to enable recording of customer users' previous Passwords.
  • count: Enter the number of previous Passwords to be saved in the history. When a customer user tries to change the password, the system does not allow the user to enter a password that is already saved in the history.
enterprise.user.lockout.defaultAttempts Number of times the enterprise user can attempt to login. If the login fails for the specified number of times, the account is locked.
enterprise.user.lockout.defaultDurationSeconds Duration of time, in seconds, in which the Enterprise user account is locked.

For example, if set to 300, the Enterprise user account will get locked if four incorrect login attempts are made within 300 seconds. If set to 60, the Enterprise user account will get locked if four incorrect attempts are made within one minute.

Note: The number of attempts is configurable via the enterprise.user.lockout.defaultAttempts system property.
enterprise.user.lockout.enabled Activates or deactivates the lockout option for the enterprise login failures.
vco.operator.resetPassword.token.expirySeconds Duration of time, after which the password reset link for an Operator user expires.
vco.operator.authentication.passwordPolicy

Defines the password strength, history, and expiration policy for Operator users.

Edit the JSON template in the Value field to define the following:

strength

  • minlength: Minimum password character length. The default minimum password length is 8 characters.
  • maxlength: Maximum password character length. The default maximum password length is 32 characters.
  • requireNumber: The password must contain at least one numeric character. Numeric requirement is enabled by default.
  • requireLower: The password must contain at least one lowercase character. Lowercase requirement is enabled by default.
  • requireUpper: The password must contain at least one uppercase character. Uppercase requirement is not enabled by default.
  • requireSpecial: The password must contain at least one special character (for example, _@!). The special character requirement is not enabled by default.
    Note: Starting from the 4.5 release, the use of the special character "<" in the password is no longer supported. In cases where users have already used "<" in their passwords in previous releases, they must remove it to save any changes on the page.
  • excludeTop: Password must not match a list of the most used passwords. Default value is 1000, representing the top 1000 most used passwords, and is configurable to a maximum of 10,000 of the most used passwords.
  • maxRepeatingCharacters: Password must not include a configurable number of repeated characters. For example, if maxRepeatingCharacters is set to ‘2’ then the Orchestrator would reject any password with 3 or more repetitive characters, like “Passwordaaa”. The default value of -1 signifies that this feature is not enabled.
  • maxSequenceCharacters: Password must not include a configurable number of sequential characters. For example, if maxSequenceCharacters is set to ‘3’ then the Orchestrator would reject any password where 4 or more characters which are sequential, like “Password1234”. The default value of -1 signifies that this feature is not enabled.
  • disallowUsernameCharacters: Password must not match a configurable portion of the user's ID. For example, if disallowUsernameCharacters is set to 5, if a user with username [email protected] attempts to configure a new password that includes ‘usern’ or ‘serna’, or any five-character string that matches a section of the user’s username, that new password would be rejected by the Orchestrator. The default value of -1 signifies that this feature is not enabled.
  • variationValidationCharacters: New password must vary from the old password by a configurable number of characters. The Orchestrator uses the Levenshtein distance between two words to determine the variation between the new and old password. The Levenshtein distance is the minimum number of single-character edits (insertions, deletions, or substitutions) required to change one word into another. 
  • If variationValidationCharacters is set to 4, then the Levenshtein distance between the new and old password must be 4 or greater. In other words, the new password must have 4 or more variations from the old password. For example, if the old password used was "kitten" and the new password is "sitting", the Levenshtein distance for these is 3, since it requires only three edits to change kitten into sitting:
    • kitten → sitten (substitution of "s" for "k")
    • sitten → sittin (substitution of "i" for "e")
    • sittin → sitting (insertion of "g" at the end).

Since the new password only varies by 3 characters from the old, “sitting” would be rejected as a new password to replace “kitten”. The default value of -1 signifies that this feature is not enabled.

expiry:
  • enable: Set this to true to enable automatic expiry of Operator user passwords.
  • days: Enter the number of days that an Operator password may be used before forced expiration.
history:
  • enable: Set this to true to enable recording of Operator users' previous Passwords.
  • count: Enter the number of previous Passwords to be saved in the history. When a Operator user tries to change the password, the system does not allow the user to enter a password that is already saved in the history.
operator.user.lockout.defaultAttempts Number of times the Operator user can attempt to login. If the login fails for the specified number of times, the account is locked.
operator.user.lockout.defaultDurationSeconds Duration of time, in seconds, in which an Operator user account is locked.

For example, if set to 300, the Operator user account will get locked if four incorrect login attempts are made within 300 seconds. If set to 60, the Operator user account will get locked if four incorrect attempts are made within one minute.

Note: The number of attempts is configurable via the operator.user.lockout.defaultAttempts system property.
operator.user.lockout.enabled Activates or deactivates the lockout option for the Operator login failures.
Table 16. Rate Limiting APIs
System Property Description
vco.api.rateLimit.enabled Allows Operator Super users activate or deactivate the rate limiting feature at the system level. By default, the value is False.
Note: The rate-limiter is not enabled in earnest, that is, it will not reject API requests that exceed the configured limits, unless the vco.api.rateLimit.mode.logOnly setting is deactivated.
vco.api.rateLimit.mode.logOnly

Allows Operator Super user to use rate limit in a LOG_ONLY mode. When the value is set as True and if a rate limit exceeds, this option logs only the error and fires respective metrics allowing clients to make requests without rate limiting.

When the value is set to False, the request API is restricted with defined policies and HTTP 429 is returned.
vco.api.rateLimit.rules.global

Allows to define a set of globally applicable policies used by the rate-limiter, in a JSON array. By default, the value is an empty array.

Each type of user (Operator, Partner, and Customer) can make up to 500 requests for every 5 seconds. The number of requests is subject to change based on the behavior pattern of the rate limited requests.

The JSON array consists of the following parameters:

Types: The type objects represent different contexts in which the rate limits are applied. The following are the different type objects that are available:
  • SYSTEM: Specifies a global limit shared by all the users.
  • OPERATOR_USER: A limit that can be set in general for all the Operator users.
  • ENTERPRISE_USER: A limit that can be set in general for all the Enterprise users.
  • MSP_USER: A limit that can be set in general for all the MSP users.
  • ENTERPRISE: A limit that can be shared between all users of an Enterprise and is applicable to all the Enterprises in the network.
  • PROXY: A limit that can be shared between all users of a Proxy and is applicable to all proxies.
Policies: Add rules to the policies to apply the requests that match the rule, by configuring the following parameters:
  • Match: Enter the type of requests to be matched:
    • All: Rate-limit all requests matching one of the type objects.
    • METHOD: Rate-limit all requests matching the specified method name.
    • METHOD_PREFIX: Rate-limit all requests matching the specified method group.
  • Rules: Enter the values for the following parameters:
    • maxConcurrent: Number of jobs that can be performed at the same time.
    • reservoir: Number of jobs that can be performed before the limiter stops performing jobs.
    • reservoirRefreshAmount: Value to set the reservoir to when reservoirRefreshInterval is in use.
    • reservoirRefreshInterval: For every millisecond of reservoirRefreshInterval, the reservoir value will be automatically updated to the value of reservoirRefreshAmount. The reservoirRefreshInterval value should be a multiple of 250 (5000 for Clustering).

Enabled: Each type limit can be activated or deactivated by including the enabled key in APIRateLimiterTypeObject. By default, the value of enabled is True, even if the key is not included. You need to include "enabled": false key to deactivate the individual type limits.

The following example shows a sample JSON file with default values:
