Machine Learning vs Spam

In the past spam was combated by setting up rules, but that worked to a point. Now machine learning is taking over, which if properly implemented can catch around 95% of unwanted mail.

Spam: the bane of the user’s existence and the cyber criminal’s friend. We’ve all, at some stage, received these unwanted emails advertising products and services we most certainly have no interest in.

Early attempts at blocking spam in the early 2000s produced a limited result. By creating antispam signatures – effectively manually created rules – the spam tide was only minimally stemmed with 50% of billions of spam mails being blocked while others still slipped through the net.

The solution was found in machine learning, which analyses immense amounts of data and works out particular patterns. What resulted was the overall enhancement of defence and a catch of around 95% of spam.

“In 2005, Trend Micro employed machine learning to discover and block spam using the Trend Micro Anti-Spam Engine (TMASE) and Hosted Email Security (HES) solutions. Spam, like everything else, evolves and we turned again to machine learning backed by quality datasets,” explains Indi Siriniwasa, Vice President of Trend Micro, Sub-Saharan Africa.

When spam floods a network, it slows it down, and there is also a chance that unwitting users may click on the spam and inadvertently download malware or viruses. Catching spam is vital to network security and it should be part of any organisation’s cyber defence. Machine learning is, however, only as effective as its capacity to examine large amounts of data accurately.

Spam may seem like an old cyber threat that appears to be outdated, but it is evolving. It looks like machine learning will be used now and in the future in order to mitigate threats – and spam.

“The consequences of not securing your network are clear: financial loss, reputational damage, disruption of operation. The best solution is to use more than one form of cyber security and take a multi-layered approach. The damage caused by a security breach is not something that any organisation can afford to neglect,” says Siriniwasa.

Queues and cash-only frustrate SA’s commuters

A new study by Visa reveals the success factors for improving travel and creating smarter cities

Published

The use of cash-only payments was a frustration for 38% of Johannesburg commuters and 37% of Cape Town-based commuters, according to a new global study by Visa. Another commuter frustration when paying for public transport has been long queues – 67% of Johannesburg commuters and 64% of Cape Town commuters.

Visa, in collaboration with Stanford University, came up with these findings in one of the largest global studies examining the growing demand for public and private transportation, and the important role digital commerce plays in driving sustainable growth.

According to the UN[i], by 2050, 68 percent of the world’s population will live in urban centres – and the number of “megacities” with populations greater than 10 million people will rise from 43 today to 51 within that same period. South Africa is no different, with the majority of the country relying heavily on the public transport system. In fact, according to the General Household Survey (GHS) for 2018, a total of 54 209 000 minibus/taxi trips take place in South African per month. 

Building on Visa’s experience working with transit operators, automotive companies and technology start-ups, Visa commissioned a global study, “The Future of Transportation: Mobility in the Age of the Megacity” to better understand the challenges commuters face today and in the future. The key findings were combined with a view of existing and near horizon innovations provided by experts at Stanford University, to better understand the technology gaps in addressing their pain points.

The South African Perspective

Payments lie at the heart of every form of travel, and will continue to become more integral as more cities move to contactless public transportation, digital payments for parking and rental services such as bikes or scooters.  Malijeng Ngqaleni, Deputy Director-General of the South African Inter-governmental Relations, states that a high as 60% of South African households spend on average of 20% of their monthly income on transport, while in rural areas this number can be as high as 31%.

Aside from cash-only payments, another commuter frustration when paying for public transport has been long queues – 67% of Johannesburg commuters and 64% of Cape Town commuters. Over the last few years, a number of mobile-driven taxi-hailing apps have been launched in the South African market to counteract these concerns and commuters are open to the possibilities presented by mobile apps. The Visa study echoed this by showing that 77% of Johannesburg commuters and 76% of Cape Town commuters would be willing to try a consolidated app to make payments for public transport.

 Mike Lemberger, SVP, Product Solutions Europe, Visa says: “The future success of our cities is intertwined with – and reliant on – the future of transportation and mobility. Visa and our partners have an important role to play, both in streamlining the payment experience for millions of commuters around the globe, and supporting public transportation authorities in their quest to build sustainable and convenient transportation solutions that improve the lives of the people who use it.”

Herman Donner, PhD and Postdoctoral Researcher from Stanford University co-authored the report and summarised: “When looking across the technology landscape, there already exist many products that could easily address people’s daily frustrations with travel.  However, none of these solutions should be developed in isolation. A major challenge therefore lies in first identifying relevant technologies that provide suitable products for the market then managing implementation in conjunction with  a broad set of stakeholder including  mobility providers, technology companies, infrastructure owners and public transport agencies.  From our research, we think that many of these small, incremental changes have the potential to make a significant difference in people’s daily travel,  whether it’s to help find parking, get the best price to refuel their car or plan their journey on public transportation.”

Women take to tech, but more needed

Published

By HAIDI NOSSAIR, Marketing Director META, Dell Technologies

$12 trillion – that is the value in additional global GDP that remains locked behind the gender gap. This is according to the latest Women Matter report from McKinsey, which also reveals startling disparities in the workplace. Even though women make up more than half of the human population, only 37% contribute to GDP on average – and in some countries that proportion is significantly lower.

The reasons for this can be put in three areas. Fewer women – 650 million fewer than men – participate in the global labour force. Women are also more likely to be in part-time employment and thus work fewer hours. Finally, female employees are more common in lower-productivity sectors than in higher-productivity areas.  Are women not being offered the opportunity or are they holding themselves back?

Among STEM careers this ratio is particularly dismal: only 24% of engineering professionals are women, and as few as 19% of careers in ICT are filled by women.

What is the cause of this? Studies have found that women pursuing STEM careers are higher in countries with more oppressive policies towards women, because those careers hold the promise for financial freedom and more social autonomy. In contrast, countries with progressive attitudes towards women tend to produce fewer female STEM graduates. Then how can we encourage women from early ages to take the path of STEM education?  And how can organizations ensure women have equal opportunity at the hiring stages.

Certainly addressing gender inequality is crucial and must not stop.. Where women are increasingly more part of the workforce, there are often still barriers preventing them from assuming higher management roles. Female entrepreneurs often struggle more to gain investment capital. Corporate cultures are rarely aligned with the pressures of balancing work and family obligations. Decision makers may simply lack exposure to the potential of female candidates. Female pioneers have also argued that women are too risk-averse when compared to men. 

Whether these assertions are true is a matter for debate – and that’s exactly why every professional man and woman should be talking about them and identify action to change the status-quo. This is not just about female rights, but about social upliftment: companies with a mixture of male and female leaders perform better across the board and companies in the top-quartile for gender diversity are 21% more likely to outperform on profitability.

The digital economy we live in today represent a golden opportunity for increased women contribution to the workforce as technology breaks the boundaries of location and time for the workplace and where labor intensive jobs may today be performed by data scientists. 

For two days in March, top professionals will gather to talk and exchange ideas around creating more roles for women, larger appreciation for female professionals, as well as counter the attitudes among women holding them back from greater career success and autonomy.
