Cybersecurity has become one of the CEO’s biggest worries, according to several surveys. Companies are investing billions in protecting their systems and training their employees. The worldwide cybersecurity market has been estimated at $77 billion in 2015 and will be $170 billion by 2020. However, the field has mostly focused on protecting systems from vulnerabilities in software and hardware. Today’s threats are no longer confined to those two places. As organizations have come to rely more and more on data-driven algorithms, risks are increasingly present in the data itself.
The pattern classification systems that machine-learning algorithms rely on may themselves exhibit vulnerabilities that can be exploited by hackers or other malefactors. One such common vulnerability is that an attacker estimates what data was used to train the machine-learning algorithm and thus is able to manipulate the input data to the algorithm itself.
