Dirty secret of network traffic

Published

on

Sophos recently announced the findings of its global survey, The Dirty Secrets of Network Firewalls, which revealed that IT managers cannot identify 45 percent of their organisation’s network traffic.

In fact, nearly one-in-four cannot identify 70 percent of their network traffic. The lack of visibility creates significant security challenges for today’s businesses and impacts effective network management. The survey polled more than 2,700 IT decision makers from mid-sized businesses in 10 countries including the US, Canada, Mexico, France, Germany, UK, Australia, Japan, India, and South Africa.

Considering the debilitating impact cyber-attacks can have on a business, it’s unsurprising that 84 percent of respondents agree that a lack of application visibility is a serious security concern. Without the ability to identify what’s running on their network, IT managers are blind to ransomware, unknown malware, data breaches and other advanced threats, as well as potentially malicious applications and rogue users. Network firewalls with signature-based detection are unable to provide adequate visibility into application traffic due to a variety of factors such as the increasing use of encryption, browser emulation, and advanced evasion techniques.

“If you can’t see everything on your network, you can’t ever be confident that your organisation is protected from threats. IT professionals have been ‘flying blind’ for too long and cybercriminals take advantage of this,” said Dan Schiappa, senior vice president and general manager of products at Sophos. “With governments worldwide introducing stiffer penalties for data breach and loss, knowing who and what is on your network is becoming increasingly important. This dirty secret can’t be ignored any longer.”

On average, organisations spend seven working days remediating 16 infected machines per month. Smaller organisations (100-1,000 users) spend on average five working days remediating 13 machines, while larger organisations (1,001-5,000 users) spend on average 10 working days remediating 20 machines per month, according to the survey.

“A single network breach often leads to the compromise of multiple computers, so the faster you can stop the infection from spreading the more you limit the damage and time needed to clean it up,” said Schiappa. “Companies are looking for the kind of next-generation, integrated network and endpoint protection that can stop advanced threats and prevent an isolated incident from turning into a widespread outbreak. Sophisticated exploits such as MimiKatz and EternalBlue reminded everyone that network protection is critical to endpoint security and vice versa. Only direct intelligence sharing between these two can reveal the true nature of who and what is operating on your network.”

IT managers are very aware that firewalls need an upgrade in protection. In fact, the survey revealed that 79 percent of IT managers polled want better protection from their current firewall. 99 percent want firewall technology that can automatically isolate infected computers, and 97 percent want endpoint and firewall protection from the same vendor which allows for direct sharing of security status information.

Security is Not the Only Risk to Businesses

Following security risks, lost productivity was cited as a concern for 52 percent of respondents when it comes to a lack of network visibility. Business productivity can be negatively impacted if IT is unable to prioritise bandwidth for critical applications.

For industries that rely on custom software to meet specific business needs, an inability to prioritise these mission critical applications over less important traffic could be costly. 50 percent of IT professionals who had invested in custom applications admitted that their firewall could not identify the traffic and therefore were unable to maximise their return on investment. Lack of visibility also creates a blind spot for the potential transfer of illegal or inappropriate content on corporate networks, making companies vulnerable to litigation and compliance issues.

“Organisations need a firewall that protects their investment in business-critical and custom applications by allowing employees to have prioritized access to the applications they need,” said Schiappa. “Increasing network visibility requires a radically different approach. By enabling the firewall to receive information directly from the endpoint security, it can now positively identify all applications – even obscure or custom applications.”

The Dirty Secrets of Network Firewalls survey was conducted by Vanson Bourne, an independent specialist in market research, in October and November 2017. This survey interviewed 2,700 IT decision makers in 10 countries and across five continents, including the US, Canada, Mexico, France, Germany, UK, Australia, Japan, India, and South Africa. All respondents were from organisations of between 100 and 5,000 users.

Sophos can deliver higher levels of network visibility with the XG Firewall and Sophos Endpoint Protection or Intercept X. For information about Sophos XG Firewall, please visit: https://www.sophos.com/en-us/products/next-gen-firewall.aspx

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.

Published

on

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 Amazon.com, 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.”
