Big data to the rescue of water networks

Published

on

Access to clean water is a basic human right, and while Government strives to provide access for all, the reality is that South Africa is currently facing a potential water crisis. But, with big data and advanced analytics software, water utilities and municipalities will be empowered to better manage water networks, writes ECKART ZOLLNER.

A shortage of clean water to areas already serviced by municipalities is becoming a growing challenge, as demand outstrips supply, aging infrastructure becomes unable to cope with volumes, and millions of litres of clean and treated water are lost due to leaks, amongst other problems. More effective management of water networks is key to addressing these and other future challenges. By harnessing the power of technology in the form of big data and advanced analytics software, water utilities and municipalities alike will be empowered to better manage water networks and as a result, improve service delivery. Technology solutions enable them to address previously unidentified issues, become more proactive about maintaining networks, respond more effectively to the growing demand and to tackle the looming water problem before it can become a full-blown crisis.

With the energy crisis being top of mind at the moment, many South Africans are unaware that water is a growing problem and should be on everyone’s radar. In fact, according to an article published in Business Day in February 2015, “The 2014 Global Risk Report conducted by the World Economic Forum rated ‘water crises’ as the third-most significant global risk, two places above that of the failure of climate change mitigation adaption”. This is a significant statement, especially when the vast majority of the South African population are not aware of the current state of water services in our country. In addition, the newspaper reported that “by 2030, it is estimated that water usage in South Africa will have grown to 2.7-billion cubic metres, leaving a 17% gap in supply and demand. Taking into account the current projected population growth and economic development rates, it is unlikely that meeting the projected demand for water resources in SA will be sustainable.”

To add to these alarming statistics, it is estimated that 36.8% of the total municipal water supplied in South Africa is lost before it reaches municipal customers, from industry to households, according to research released by the Water Research Commission (WRC). One of the major reasons for this wastage is due to undetected leaks, which are an issue because the majority of the water network is buried underground, and leaks are often difficult to pinpoint until they cause further damage such as sinkholes or collapsed infrastructure. This wasted water is still undergoing costly treatment to ensure it is clean and potable, however, it cannot be charged for and fails to generate revenue for municipalities. This in addition to the cost of fixing massive infrastructure issues when they occur puts increasing strain on already tight budgets. This in turn takes funding away from Government’s ability to deliver services to more people and provide access to water for all.

The upshot of this situation is that municipalities and water utilities face the challenge not only of having to manage the demand for clean water and ensuring there is sufficient supply when already faced a shortage, but they are also losing money too. However, new technology solutions such as big data analytics have the potential to turn this challenge around.

Water utilities by their very nature generate significant volumes of data, which can be harnessed and analysed to provide insight for improved management and decision-making ability. Utilising intelligent data analytics based on past usage data combined with predictive flow modelling as well as real-time information on water levels, weather reports, water flows, pressure and more, significant events can be detected and alerts sent out to highlight potential issues. This type of data analysis can create alerts for water leaks and loss, burst pipes, loss of water pressure and faulty metres, as well as usage patterns, water quality issues and much more. This helps water utilities and municipalities to generate knowledge about network inefficiencies, water loss and other hazards. In addition, it can help to proactively detect leaks for faster resolution, and can help municipalities to prioritise repairs and maintenance based on the likelihood of problems and failures, as well as perform accurate network planning and optimisation.

This type of end-to-end water network management, delivered as a cloud-based Software-as-a-Service (SAAS), can greatly assist water utilities to avert a water crisis. By providing instant visibility into problematic areas of the water network, many improvements can be made. It provides real-time data and analysis for quicker response to events, allows municipalities to pre-empt issues and deliver improved customer service, amongst other benefits. With a growing population with increasing need for water, both for consumer and industry, improved management and service delivery is essential, and the goal is to reduce non-revenue water losses to between eight and 10%. Technology that assists with early leak detection, proactive maintenance and better management is essential, and ultimately supports the global drive towards the creation of smart cities.

Wannacry still alive

One and a half years after its epidemic, WannaCry ransomware tops the list of the most widespread cryptor families and the ransomware has attacked 74,621 unique users worldwide.

Published

on

These attacks accounted for 28.72% of all users targeted by cryptors in Q3 2018. The percentage has risen over the last year, demonstrating more than two thirds growth against Q3 2017, when its share in cryptor attacks was 16.78%. This is just one of the main findings from Kaspersky Lab’s Q3 IT threat evolution report. 

A series of cyberattacks with WannaCry cryptor occurred in May 2017 and is still considered to be one of the biggest ransomware epidemics in history. Even though Windows released a patch for its operating system to close the vulnerability exploited by EternalBlue 2 months prior to the start of the attacks, WannaCry still affected hundreds of thousands devices around the globe. As cryptors do, WannaCry turned files on victims’ computers into encrypted data and demanded ransom for decryption keys (created by threat actors to decipher the files and transform them back into the original data) making it impossible to operate the infected device.

The consequences of the WannaCry epidemic were devastating: as the victims were mainly organisations with networked systems – the work of businesses, factories and hospitals was paralysed. Even though this case demonstrated the dangers cryptors pose, and most of PCs around the world have been updated to resist the EternalBlue exploit, the statistics show that criminals still try to exploit those computers that weren’t patched and there are still plenty of them around the globe.

Overall, Kaspersky Lab security solution protected 259,867 unique users from cryptors attacks, showing a substantial rise of 39% since Q2 2018, when the figure was 158,921. The growth was rapid yet steady, with a monthly observed increase in the number of users.

The rising share of WannaCry attacks is another reminder that epidemics don’t end as fast as they start – there are always long-running consequences. In the case of cryptors, attacks can be so severe that it is necessary to take preventive measures and patch the device, rather than deal with encrypted files later,” said Fedor Sinitsyn, security researcher at Kaspersky Lab.

 To reduce the risk of infection by WannaCry and other cryptors, users are advised to:

  • Always update your operating system to eliminate recent vulnerabilities and use a robust security solution with updated databases. It is also important to use the security solution that has specialised technologies to protect your data from ransomware, as Kaspersky Lab’s solutions do. Even if the newest yet unknown malware does manage to sneak through, Kaspersky Lab’s System Watcher technology is able to block and roll back all malicious changes made on a device, including the encryption of files.
  • If you have bad luck and all your files are encrypted with cryptomalware, it is not recommended to pay cybercriminals, as it encourages them to continue their dirty business and infect more people’s devices. It is better to find a decryptor on the Internet – some of them are available for free here: https://noransom.kaspersky.com/

·         It is also important to always have fresh backup copies of your files to be able to replace them in case they are lost (e.g. due to malware or a broken device), and store them not only on the physical object but also in cloud storage for greater reliability (don’t forget to protect your cloud storage with strong hack-proof password!)

·         If you’re a business, enhance your preferred third-party security solution with the newest version of the free Kaspersky Anti-Ransomware Tool.

·         To protect the corporate environment, educate your employees and IT teams, keep sensitive data separate, restrict access, and always back up everything.

·         Use a dedicated security solution, such as Kaspersky Endpoint Security for Business that is powered by behaviour detection and able to roll back malicious actions. It should also include Vulnerability and Patch management features that automatically eliminates vulnerabilities and installs updates. This reduces the risk of vulnerabilities in popular software being used by cybercriminals.

·         Last, but not least, remember that ransomware is a criminal offence. You shouldn’t pay. If you become a victim, report it to your local law enforcement agency.
