The reliance of systems on computational assets makes them vulnerable to attack. Traditionally, networks and systems are monitored by cyber security operators who rely on intrusion detection systems to provide indicators of compromise via alerts. With the growing number and frequency of alerts and the increasing sophistication of attacks, human operators are incapable of keeping pace. Data-driven and statistical tools, such as algorithms from artificial intelligence (AI), have the potential to assist in this area. These AI technologies enable the collection of synchronized, real-time capabilities to discover, define, analyze, and mitigate cyber threats and vulnerabilities with limited human intervention. Network intrusion detection systems (NIDS) are a primary component of the broader practices in network security monitoring for cyber security operations at enterprise, operational and tactical environments. Today, integrating AI components into NIDS can help identify patterns associated with known threats or detect abnormal behavior. These AI-based NIDS, however, are susceptible to adversarial AI evasion attacks. In this talk, I will discuss how data augmentation techniques can be used to improve the adversarial robustness of AI-based NIDS for network security monitoring. Particularly, I will discuss how meta-heuristics can be used to generate adversarial examples to then be combined as part of a meta-learning adversarial training framework.<\/p>    <\/div>\n<\/div>\n<!-- \/module text -->        <\/div>\n                        <\/div>\n        <\/div>\n        <\/div>\n<!--\/themify_builder_content-->","protected":false},"excerpt":{"rendered":"<p>Nathaniel Bastian Nathaniel D.
