The Power of Vectors and Embedding in Bolstering Cybersecurity

In the face of ever-evolving cybersecurity threats, a constant influx of information demands innovative tools and methods for sifting through vast datasets. The challenge becomes particularly daunting when determining the nuances and intentions behind the text.

For instance, as phishing attacks are becoming increasingly sophisticated, how can we identify what is malicious from what is benign, especially when they seem so alike? Enter Elastic Learned Sparse EncodeR (ELSER): a potent tool designed to understand text at a semantic level and discern the patterns and intents underneath the surface.

This chapter dives deep into ELSER, a pre-trained model provided by Elastic that has harnessed the power of vectors without burdening the user with its intricacies. We will address the following key topics:

• Overview of ELSER, where we will delve into its essence and role in semantic search
• Handling data with ELSER...
