High cost of hackers getting into the PBX

Published

on

Many VoIP customers are surpassed when they receive outrageous phone bills. This is often due to PBX hacking where a fraudster hijacks a telephone system to place premium calls.

Unsuspecting VoIP customers are often surprised when they receive outrageous phone bills, especially when their telephone service providers do not explain the risks of toll fraud, better known as PBX hacking. International fraudsters are constantly hijacking telephone systems and using them to place calls to premium charge-by-the-minute numbers.

SIP trunking is a VoIP service that allows service providers to deliver telephone services to customers equipped with SIP-based IP-PBX. Without the correct preventative measures, SIP trunking often results in huge unforeseen costs that can cripple a small to medium size organisation when their IP-PBX or SIP trunk is hacked.

Euphoria Telecom CEO George Golding says a free SIP trunk doesn’’t necessarily mean cost savings. “Most local VoIP service providers don’t have sophisticated fraud prevention systems in place to prevent hackers from running up charges if a PABX is hacked and they also don’t take liability for the fraudulent charges.”

Businesses often use local service providers that normally lack such antifraud systems, leaving customers to foot the bill. The law is also not much help, because no regulations require carriers or service providers to reimburse customers for fraudulent activity.

“If your VoIP provider doesn’t offer control mechanisms to dramatically reduce or prevent fraudulent use of your SIP account, you may want to look into using a different provider,” says Golding.

Euphoria has introduced a level of security on their SIP trunk and Cloud PBX services to dramatically reduce the risks associated with toll fraud. Its VoIP-based Cloud PBX phone system and SIP trunks restricts international calls on a granular level.

It can restrict specific extensions on its Cloud PBX and also restrict calls to specific countries on a per-extension and per-SIP account basis. Specific extensions can be programmed to allow or prohibit international calls to specific countries.

This way one can allow specific international countries to be called on those extensions by users that require it, but still block all high risk toll fraud countries – even in the event where an account is compromised.

Legion gets a pro makeover

Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER

Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.

The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.

The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme. 

The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.

The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.

The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000

Published

on

By EDWARD CARBUTT, executive director at Marval Africa

The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.

However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.

ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?

ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks. 

ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?

The link to information security compliance

Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.

So, how are these standards different?

Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more

Why ISO 20000?

Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is.  ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does.  ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.

Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
