FEATURE: ARTIFICIAL INTELLIGENCE ////////////////////////////////////////////////////////////////////// algorithms, as the data set required can vary based on a range of situational factors. different habits so things that are normal may often look like anomalies. If attacks are unique to an industry, such as on Industrial Control Systems, the AI will need to be fed data specific to that context. However, the algorithm would need to be tweaked when dealing with data sets related to a sector within that industry, for instance in the commercial or HR side of the business. However, the algorithm also needs to be specific if you want to identify strong threat signals, but at the same time this makes the data set narrower. It’s about finding that balance and ensuring AI is fed enough specific data to function at an effective level across any sector. HACKING ONCE TOOK DEDICATION AND EXPERTISE, WITH ZERO-DAY ATTACKS TARGETING MOSTLY UNKNOWN VULNERABILITIES. You can only take a general approach when dealing with generic attacks, like spam filtering, which can be spotted by the AI no matter what context or industry these attacks operate within. AI can be a contradiction in itself sometimes. While it needs to be specific, it only really becomes effective when it’s used to spot anomalies in large data sets. For instance, if you look for an anomaly in a smaller group of people, everyone will have How can AI help overcome the challenges facing CISO on a daily basis? AI’s main value is that it provides CISOs with the opportunity to more effectively deploy their human analysts against potential cyberattacks and data breaches. With this enlarged target surface area and a growing number of active hackers, our experts need to sort through more data than is humanly possible to detect all malicious activity. AI is essentially there to augment the role of human security experts. Machine Learning algorithms are key in helping us pinpoint anomalous data – some of which is bound to be malicious – but the AI is rendered totally useless without a crack team in place to add technical and contextual awareness to the data. CISOs and CTOs need to understand that while AI is here to stay, as data sets become more and more complex, it will not come to replace human experts. Ultimately though, just because an organisation has an AI system in place, this does not mean it is secure. Countering cyberthreats is a constant game of cat and mouse between the cybersecurity experts and hackers. Hackers always want to get the maximum reward from the minimum effort, tweaking known types of attack as soon as these are detected by the AI. CTOs need to, therefore, make sure that the AI system is routinely exercised and fed new data. Think of it like this: If a company has an employee who is trusted across the board, that employee still needs to be regularly evaluated to ensure their performance levels remain high. In the same way as humans, AI needs to be reviewed and trained – and only once we are sure that the AI is performing can we trust it to take swift and decisive action. n Ensuring the success of AI in retail Forward-thinking retailers are using Artificial Intelligence (AI) to ensure they’re sitting at the top of the tree in an often turbulent and unpredictable sector. And as Mylo Portas, Head of Retail, Peak, tells us, those who are taking the market by storm are using the technology to find new ways of driving sales and improving the experience of their increasingly expectant customers. 42 INTELLIGENTCIO www.intelligentcio.com
