Open Wi-Fi or unencrypted Internet access may sound enticing, but there are thousands of threats that come with it. BRENDAN MCARAVEY, Country Manager at Citrix South Africa, believes it is imperative for users to protect their devices before taking any chances.
“Open”, Wi-Fi is available almost everywhere, different cities have their own implementation strategies. While cities like Cape Town have implemented a strategy where the city owns and manages WiFi points to the value of R10 million. Tshwane on the other hand has relied on their private sector partner, the NGO Project Isizwe for their roll out. And, City of Johannesburg in January 2017 rolled out 1 000 WiFi hotspots in public areas.
Open Wi-Fi is generally defined as wireless networks that provides free, unencrypted access without the need to identify yourself, or for the Wi-Fi access point to identify itself (authentication). Providing open Wi-Fi is considered a value-added service or feature of many consumer-oriented businesses today. Combined with sometimes unacceptable cellular bandwidth or signal strength, and data plan limits, it is difficult to resist the lure of open, free Wi-Fi.
But in life, cause and effect is a reality virtually everyone acknowledges. The convenience of open Wi-Fi (cause) introduces security threats (effect), and places the responsibility of safely utilising these services on the end user (effect). The principal threat impacting users of open Wi-Fi is traffic sniffing, or eavesdropping, whereby an attacker “listens” in on wireless traffic that is not encrypted, potentially providing access to sensitive data. Probably the best public display of the consequences surrounding the use of unencrypted, open Wi-Fi is the “Wall of Sheep”, a staple at the DefCon security conference in Las Vegas for more than fifteen years.
The Wall of Sheep tracks people (sheep) at the conference that use open, unencrypted Wi-Fi to send email, login to websites, message their friends, etc. These sheeple (Riverside’s term, not ours) are publicly shamed by posting redacted login details for each of their infractions on the “wall of sheep”. In virtually every case, these conference attendees connected to either DefCon-Open, the purpose-built open Wi-Fi network hosted at DefCon for catching unsafe Internet users, or a researcher or attacker’s “rogue” open Wi-Fi. DefCon attendees can connect securely to the official, encrypted DefCon Wi-Fi network by downloading their certificate.
The above mentioned dangers of using ‘Open Wi-Fi’ are fast becoming a reality in South Africa as well. The high cost of data often forces people to use these hotspots, most often, for job searches, banking and other essential activities which are also be data intensive. This highlights that there is a growing need to create awareness among South Africans that; security of personal information is at high-risk when using these hotspots.
Citrix has educated customers about wireless security since at least 2010. Today, customers have several options available to help secure end users’ Wi-Fi use when outside the office. One of the easiest and best-known solutions is utilising NetScaler Gateway, which provides network protection via Full VPN access to its users. In addition to encrypting traffic from the remote device to the NetScaler, access profiles can be configured to forward (proxy) traffic to a content filtering system or other security infrastructure for inspection.
After all, there is more to networking than HTTP and HTTPS (“HTTP/S”). In fact, some mobile applications don’t use HTTP/S at all. Organisations may never know all of the apps a user has installed unless a full device management solution is deployed, encrypting all traffic with Full VPN is a more sensible choice. And with NetScaler Gateway, organisations can keep track of these remote users effectively.
We do not live in a perfect world, and cyber-attacks are now more frequent than ever before. It is essential for people to know that getting access to open WiFi does make life easier, but it can soon turn into a problematic situation as well. It is imperative that people become aware of the dangers and protect themselves accordingly.
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
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.
