Make the vulnerable visible

Dealing with encrypted traffic can be complex, costly, and disruptive. The problem escalates immeasurably if you are operating blind to cyber threats, which is basically what businesses are doing without a comprehensive SSL/TLS strategy in place, writes SIMON MCCOLLOUGH, Major Channel Account Manager, F5 Networks.



Regrettably, too many still misplace their trust in inadequate security solutions, often leaving IT departments with an unenviable choice: let the traffic go uninspected or suffer extreme application performance losses.

In the new age of digital consent and compliance, can you afford to expose vulnerable data to high risk due to operational myopia, which will damage your brand reputation and lose customer trust?

Bypassing traditional security

Encrypting data-in-transit with SSL/TLS is already standard practice. Important security initiatives, such as built-in web browser warnings and the EU General Data Protection Regulation (GDPR), have significantly improved privacy awareness and helped mitigate data breach magnitudes.

While this is all good news, cybercriminals will always find a way to hide threats within encrypted payloads or use encrypted channels to propagate malware and exfiltrate data. Traditional security inspection solutions are becoming an increasingly easy challenge to overcome.

Ostensibly, gaining full visibility into encrypted traffic is never easy. Most organisations typically lack a central control to implement decryption policies across the multiple security inspection devices commonly found in the security chain. Consequently, security teams resort to daisy-chaining devices or tedious manual configurations to support inspection activities, increasing latency, complexity, and risk. All too often, the provisioning of network and security services, such as firewalls and security gateways, can turn into a time-intensive and error-prone process if SSL inspections are in the mix.

At the same time, eavesdropping and man-in-the-middle hijacks will continue to rise due to superannuated transport layer encryption standards still being in use, even though they have been officially retired as “broken”.

Many are also struggling to get the most out of the technology or understand how to best deploy it. Recent research from F5 Labs reveals that while 63% of surveyed business respondents use SSL/TLS encryption for their web applications, only 46% use it for the majority of their applications.

Furthermore, 47% of organisations said they use self-signed certificates, which reduces application trustworthiness. This is unacceptable. Security teams need to ensure all applications are running suitable levels of encryption and have adequate third-party signed certificates in place.

There is far too much confusion and bad practice out there. It’s high time businesses get their heads around growing SSL/TLS complexities, not to mention the associated impacts on data breaches, compliance, and privacy.

Improving your cryptographic posture

Fortunately, it is not all opaque doom and gloom. With the right encryption orchestrator solution, it is now possible to dramatically reduce the risk of encrypted attacks through dynamic service-chaining, which enables automatic insertion of physical or virtual security service appliances.

It is important to note that the best tools always balance app performance and risk mitigation, giving security teams all-encompassing visibility into encrypted traffic. This allows them to effectively manage and quickly respond to previously invisible threats. In addition, improved threat detection and attack remediation capabilities can improve overall operational efficiency across your entire application security infrastructure. As a rule of thumb, your SSL/TLS strategy should be able to:

·        Defend against encrypted threats by scaling SSL across multiple security devices blind to encrypted traffic

·        Prevent data loss and ensure compliance by gaining visibility into all data connection points (inbound and outbound traffic)

·        Have a single point of control across multiple security tools for greater efficiencies

·        Prevent attacks by reducing risks of selective blind spots

·        Reduce latency with high-performance decryption and encryption of inbound and outbound SSL/TLS traffic

·        Leverage policy-based service chaining to drive greater efficiencies within your security stack

·        Load balance between devices to minimise bottlenecks

·        Reduce the administrative burden with centralised key management, saving considerable time and money by offloading SSL instead of terminating on the device itself

Securing tomorrow

The ultimate goal is to simplify the SSL/TLS management process, keeping data secure and gaining full visibility into encrypted traffic without compromising application speed or availability.

To do this, businesses need the ability to properly scan inbound and outbound traffic. Crucially, they have to vividly visualise and analyse the nature of today’s attacks vectors in order to secure their applications, which are by far the most valuable, data-laden assets at stake. Remember, there’s nowhere to hide when it comes to the cybercriminals’ encryption corruption. Now is the time to future-proof yourself against tomorrow’s threats.

Online retail gets real

After decades of experience in selling online, retailers still seek out the secret of reaching the digital consumer, writes ARTHUR GOLDSTUCK.



It’s been 23 years since the first pizza and the first bunch of flowers was sold online. One would think, after all this time, that retailers would know exactly what works, and exactly how the digital consumer thinks.

Yet, in shopping-mad South Africa, only 4% of adults regularly shop online. One could blame high data costs, low levels of tech-savviness, or lack of trust. However, that doesn’t explain why a population where more than a quarter of people have a debit or credit card and almost 40% of people use the Internet is staying away.

The new Online Retail in South Africa 2019 study, conducted by World Wide Worx with the support of Visa and Platinum Seed, reveals that growth is in fact healthy, but is still coming off a low base. This year, the total sale of retail products online is expected to pass the R14-billion mark, making up 1.4% of total retail.

This figure represents 25% growth over 2017, and comes after the same rate of growth was seen in 2017. At this rate, it is clear that online retail is going mainstream, driven by aggressive marketing, and new shopping channels like mobile shopping. 

But it is equally clear that not all retailers are getting it right. According to the study, the unwillingness of business to reinvest revenue in developing their online presence is one of the main barriers to long-term success. Only one in five companies surveyed invested more than 20% of their online turnover back into their online store. Over half invested less than 10% back.

On the surface, the industry looks healthy, as a surprisingly high 71% of online retailers surveyed say they are profitable. But this brings to mind the early days of, in 1996, when founder Jeff Bezos was asked when it would become profitable.

He declared that it would not be profitable for at least another five years. And if it did, he said, it would be in big trouble. He meant that it was so important for long-term sustainability that Amazon reinvest all its revenues in customer systems, that it could not afford to look for short-term profits.

According to the South African study, the single most critical factor in the success of online retail activities is customer service. A vast majority, 98% of respondents, regarded it as important. This positions customer service as the very heart of online retail. For Amazon, investment back into systems that would streamline customer service became the key to the world’s digital wallets.

In South Africa online still make up a small proportion of overall retail, but for the first time we see the promise of a broader range of businesses in terms of category, size, turnover and employee numbers. This is a sign that our local market is beginning to mature. 

Clothing and apparel is the fastest growing sector, but is also the sector with the highest turnover of businesses. It illustrates the dangers of a low barrier to entry: the survival rate of online stores in this sector is probably directly opposite to the ease of setting up an online apparel store.

A fast-growing category that was fairly low on the agenda in the past, alcohol, tobacco and vaping, has benefited from the increased online supply of vapes, juices and accessories. It also suggests that smoking bans, and the change in the legal status of marijuana during the survey, may have boosted demand. 

In the coming weeks, we can expect online retail to fall under the spotlight as never before. Black Friday, a shopping tradition imported “wholesale” from the United States, is expected to become the biggest online shopping day of the year in South Africa, as it is in the USA.

Initially, it was just a gimmick in South Africa, attempting to cash in on what was a purely American tradition of insane sales on the Friday after Thanksgiving Day, which occurs on the third Thursday of November every year. It is followed by Cyber Monday, making the entire weekend one of major promotions and great bargains.

It has grown every year in South Africa since its first introduction about six years ago, and last year it broke into the mainstream, with numerous high profile retailers embracing it, and many consumers experiencing it for the first time. 

It is now positioned as the prime bargain day of the year for consumers, and many wait in anticipation for it, as they do in the USA. Along with Cyber Monday, it provides an excuse for retailers to go all out in their marketing, and for consumers to storm the display shelves or web pages. South African shoppers, clearly, are easily enticed by bargains.

Word of mouth around Black Friday has also grown massively in the past two years, driven by both media and shoppers who have found ridiculous bargains. As news spreads that the most ridiculous of the bargains are to be had online, even those who were reticent of digital shopping will be tempted to convert.

The Online Retail in SA 2019 report has shown over the years that, as people become more experienced in using the Internet, their propensity to shop online increases. This is part of the World Wide Worx model known as the Digital Participation Curve. The key missing factor in the Curve is that most retailers do not know how to convert that propensity into actual online shopping behaviour. Black Friday will be one of the keys to conversion.

Carry on reading to find out about the online retailers of the year.

Reliable satellite Internet?

MzansiSat, a satellite-Internet business, aims to beam Internet connections to places in South Africa which don’t have access to cabled and mobile network infrastructure, writes BRYAN TURNER.



Stellenbosch-based MzansiSat promises to provide cheap wholesale Internet to Internet Service Providers for as little as R25 per Gigabyte. Providers who offer more expensive Internet services could benefit greatly from partnering with MzansiSat, says the company. 

“Using MzansiSat, we hope that we can carry over cost-savings benefits to the consumer,” says Victor Stephanopoli, MzansiSat chief operating officer.

The company, which has been spun off from StellSat, has been looking to increase its investor portfolio while it waits for spectrum approval. The additional investment will allow MzansiSat’s satellite to operate in more regions across Africa.

The MzansiSat satellite is being built by Thales Alenia Space, a French company which is also acting as technical partner to MzansiSat. In addition to building the satellite, Thales Alenia Space will also be assisting MzansiSat in coordinating the launch. The company intends to launch the satellite into the 56°E orbital slot in a geostationary orbit, which enables communication almost anywhere in Africa. The launch is expected to happen in 2022. 

The satellite will have 76 transponders, 48 of which will be Ku-band and 28 C-band. Ku-band is all about high-speed performance, while C-band deals with weather-resistance. The design intention is for customers of MzansiSat to choose between very cheap, reliable data and very fast, power-efficient data. 

C-band is an older technology, which makes bandwidth cheaper and almost never affected by rain but requires bigger dishes and slower bandwidth compared to Ku-band connections. On the other hand, Ku-band is faster, experiences less microwave interference, and requires less power to run – but is less reliable with bad weather conditions.

MzansiSat’s potential military applications are significant, due to the nature of the military being mobile and possibly in remote areas without connectivity.  Connectivity everywhere would be potentially be life-saving.

Consumers in remote areas will benefit, even though satellite is higher in latency than fibre and LTE connections. While this level of latency is high (a fifth of a second in theory), satellite connections are still adequate for browsing the Internet and watching online content. 

The Internet of Things (IoT) may see the benefits of satellite Internet before consumers do. The applications of IoT in agriculture are vast, from hydration sensors to soil nutrient testers, and can be realised with an Internet connection which is available in a remote area.

Stephanopoli says that e-learning in remote areas can also benefit from MzansiSat’s presence, as many school resources are becoming readily available online. 

“Through our network, the learning experience can be beamed into classrooms across the country to substitute or complement local resources within the South African schooling system.”
