TELEPHONE SYSTEMS SECURITY GUIDANCE NOTES

IntroductionToll fraud and Hacking is a multi-dollar business in the USA, which has now arrived in theUK.

Hackers use various methods to access a PABX, which may be done for many reasons, butprimarily for obtaining free calls. This inevitably results in very large telephone bills for thehacked company.

What is Hacking?When telephone system hacking began, it was achieved by people who used PCs to breakinto the voice mail system. Hackers used mailboxes to spread Information, conduct drug

sales, post stolen credit numbers or simply to record nasty greetings for callers. Nowhowever hackers use telephone systems to obtain outgoing trunks, they then sell thisaccess to a community of people for dialling expensive international calls. If the incomingtrunks are Freephone numbers the fraudsters enjoy the benefit of completely free calls, withthe hacked company paying the bill for both ends of the call.

Why has Hacking Now Become a Problem in the UK?Hacking has become a serious problem in the UK for the following reasons.

The sophistication of telephone systems now available to companies in the UK. OFTEL now allows many features on PABXs such as PSTN trunk to PSTN trunk

transfer to be used. Wide use of Maintenance modems on telephone systems. Sophisticated Voice Mail Systems. Widespread use of the Internet which is used for posting Hacking information. Widespread use of modems in the UK which has resulted in cheap and user friendly

modems being available on the market. The huge demand for free international calls as overseas nations develop their

telephone networks and business requirements. Customers either ignoring or not being aware of the hacking problem thereby leaving

their telephone systems open to fraud. The widespread use of the Freephone numbers 0500 and 0800.

Direct Inward System Access (DISA).

By far the greatest current problem in the UK for PABX owners is toll fraud, aservice that has millions of potential "customers".

What Can Be Done To Prevent The PABX From Being Hacked?Hacker activity may not be completely avoidable but steps can be made to reduce the risks.The principle aim of telephone security is to deter hackers from taking control of acustomers telephone system. Fraudsters after free calls will move on to other PABXs if ittakes too long to break into a system.

Trunk Access Educate everyone about not connecting anyone they do not know to an outgoing trunk. Ensure effective call barring has been carried out barring the following numbers may

reduce the possibility of the system being used for fraudulent calls.

Note: No call barring plan should be limited to the codes listed below.

7 (CIS- former USSR)234 (Nigeria)1809 (Jamaica)86 (China)91 (India)92 (Pakistan)155 (International Operator)

The customer should consider call allow rather than call bar on their system. Theyshould also bar access to countries that they do not require telephone access to.

Do not allow Voice Mail Systems to have trunk access.

System InformationGuard information on the Telephone system:

Network service providers authorisation codes should be kept in a secure location. Do not write authorisation codes in notebooks.

Keep all System Manuals in a secure location and do not write information that may beuseful to hackers in these manuals. Cabinets used to store system manuals must bekept locked.

Customers and engineers should dispose of sensitive information securely and not leaveinformation useful to hackers in waste bins.

Equipment Room AccessAccess to the telephone system should be restricted as much as possible. Customers shouldask for identification before allowing access to the telephone system. Engineers shouldrecord all site visit details in the site logbook.

Monitoring The Telephone SystemFraudulent calls and Hacking attempts can be detected if the Call logging Information isreviewed on a daily basis. Immediate correct action should be taken and the NetworkService Provider should be informed as soon as possible.

Engineering Level MeasuresEngineers must be security conscious at all times when dealing with a customer's PABX.

Change the default passwords/Passcodes to new codes when an installation iscompleted, particularly the engineering Passcodes.

Destroy any customer code that has been written down before leaving site.

Configure systems in accordance with the equipment security guidance information.

DO NOT enable features on the telephone system that allows Dial Through. Unless the customer requests this feature.

Disable any feature on the system which allows or facilitates Dial Throughapplications, unless specifically requested otherwise by the customer.

Advise and configure any PIN digits used by the customer to be the maximum numberof permitted digits. These PIN numbers must not include the customers STD numberor be related to extension numbers.

Hackers are adept at finding the numbers of maintenance modems. If a maintenancemodem is used, the allocated extension number should be different for each site.

Maintenance modems should ideally be configured as dial back modems so that theyring back to the service centre. Under no circumstances should the customer be toldthe passcode for the maintenance modem.

Keep all documentation up to date, accurate and secure. If a telephone system hasbeen successfully hacked and the perpetrator is found and prosecuted, documentssuch as site visit log books and configuration manual may be required as evidence incourt.

DO NOT leave the customer with spare configured Mail box numbers and onlyconfigure the minimum amount of spare extension numbers. Ideally there should beno spare extension numbers.

Educate the customer to ask for security pass from engineers requesting access to theswitch room. Make sure that the customer is aware of who should be allowed entry to

the equipment room and what their security passes would look like.

The combined effect of carrying out these countermeasures will reduce the likelihoodof a telephone system being hacked.
