Security - NEC SL2100 Quick Install Manual

Security

10 – Security
You should ensure that the customer's system is secure from Toll Fraud.
The Health Check feature within the InGuard Application can be used to check the system for
weaknesses.
The InGuard on-board application can also be used to give the customer ongoing protection from Toll
Fraud.
Refer to the InGuard Toll Fraud Guard Installation and User manuals for details.
Additional licenses are required to run On-board applications.
Use the Toll Restriction section of this guide to setup outgoing call restriction of numbers the customer does not
want to dial.
There is also a separate Quick Install Guide for Toll Restriction.
Voicemail and Toll Fraud Security

Do not allow outgoing trunk access for the voicemail ports unless the customer wants the voicemail
system to do place outgoing calls.

Do not allow trunk to trunk connection for the voicemail ports unless the customer wants incoming
callers to be transferred to another trunk

If the voicemail does have access to outgoing trunk then ensure you have Toll Restriction setup to
prevent dialling of unwanted numbers.
It is strongly recommended that the customer has visibility of outgoing calls made by the voicemail
system, for example InGuard or a call logger.

If a user has message notification enabled then it is strongly recommended that the user sets a security
code for their mailbox. Security code must then be entered before the called party can retrieve your
messages via the notification call.
Voicemail mailbox Security

Remove mailboxes from any un-used extensions on the system.

Do not set Logon unless required by the customer. Logon to voicemail allows incoming callers to access
the user's mailbox, ensure the mailbox has a security code.
Security code is set by the user: Select soft key Setup – Code and enter a 4 digit code.

Do not set the Routing Mailbox option for subscriber mailboxes unless the user wishes to press # during
their greeting to logon to their mailbox i.e. for remote access to the user's mailbox messages.
Auto Attendant Dial Actions
Make sure the outside callers that are answered by the VRS can only dial known digits.
Call Management
Consider the use of a call management system or call logger to give the customer visibility of calls, InReports
can be used for this.
Trunk to Trunk Transfer / Call Forward External
Do not allow these unless the customer requests the feature, ensure you setup adequate toll restriction to
prevent toll fraud.
