Abstract
Electronic mail, or email, is a method for com-municating using the internet which is inexpensive, effective, and fast. Spam is a type of email where unwanted messages, usually unwanted commercial messages, are distributed in large quantities by a spammer. The objective of such behavior is to harm email users; these messages need to be detected and prevented from being sent to users in the first place. In order to filter these emails, the developers have used machine learning methods. This paper discusses different methods which are used deep learning methods such as a Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) models with(out) a GloVe model in order to classify spam and non-spam messages. These models are only based on email data, and the extraction set of features is automatic. In addition, our work provides a comparison between traditional machine learning and deep learning algorithms on spam datasets to find out the best way to intrusion detection. The results indicate that deep learning offers improved performance of precision, recall, and accuracy. As far as we are aware, deep learning methods show great promise in being able to filter email spam, therefore we have performed a comparison of various deep learning methods with traditional machine learning methods. Using a benchmark dataset consisting of 5,243 spam and 16,872 not-spam and SMS messages, the highest achieved accuracy score is 96.52% using CNN with the GloVe model.

Summary
Effective, and fast way to exchange messages using the Internet. Spam email can contain malicious content, such as a phishing attack and/or malware. Despite considerable cybersecurity improvements and continuous development, spam email and malware damage caused by spam emails can prevent communication, create increased traffic, and waste users’ time where the spam emails must be manually deleted. It is possible to miss important email messages that are accidentally deleted when manually removing large numbers of spam messages. Cybersecurity is a hot topic in industrial information and operational technologies. The definition of cybersecurity is technologies and processes which are built to protect computer hardware, software, networks, and data from unauthorized access, vulnerabilities, terrorists, and hackers. Cybersecurity is the protection of the internet, information, and networkbased digital equipment from unauthorized access and amendment [5]. Machine learning classifiers have had a prominent role in intelligent system development
