Deploying AI for cyber defence in depth?

As any business grows, data sharing increases in both volume and frequency. Every one of these digital relationships presents an expanding set of cyber risks.

Cyber security has become a major priority for every organisation. The right controls and procedures must be put in place to detect potential attacks and protect against them. However, with the ever increasing risk of a cyber-attack businesses are finding it increasingly difficult to keep up with the rapidly evolving cyber threats?

Budget available for deployment of ‘defence in depth’ is being stretched to the limits and thus security professionals are expected to spend more on tools that use AI and machine learning, which would help with the extra workload caused by the increasing risk of an attack, and improve defences.

Malware is often transferred to ICT Systems within encrypted web traffic, and sensitive data sent through cloud systems. This suggest that the most effective way to manage the concomitant exposures is to deploy the relevant tools which encompass deep learning capability and embedded artificial intelligence to timeously and effectively monitor, detect and prevent the use of encryption for masking malicious activity.

A learning curve

It is often suggested that, over time, artificial intelligence (AI) will be able to learn how to automatically detect unusual patterns in encrypted web traffic and the Internet of Things (IoT) environments.

Neural networks facilitating AI will soon be available for deployment in the struggle to substantially improve network security defences. Businesses, governments and other organisations have not been able to find staff with the necessary skills required for effective control of network and computer security. The deployment of automated system controls which rely on AI and machine learning tools will certainly reduce the demand for skilled network security professional staff / administrators to help overcome these substantial skill gaps.

It is a well-established fact, that …
