This assignment consists of a report worth 30 marks. Delays caused by student's own computer downtime cannot be accepted as a valid reason for late submission without penalty. Students must plan their work to allow for both scheduled and unscheduled downtime.
Submission instructions: You must submit an electronic copy of all your assignment files via VU Collaborate Dropbox. You must include both your report, source codes and necessary data files. Assignments will not be accepted through any other manner of submission. Students should note that email and paper-based submissions will ordinarily be rejected.
Late submissions: Submissions received after the due date are penalized at a rate of 30% (out of the full mark) per day, no exceptions. Late submission after 3 days would not be accepted, and mark would be recorded as zero (0).

Machine learning methods use effectively to detect malicious websites. In this assignment, you are required to classify malicious websites by using provided datasets. The features have been extracted and clearly structured in CSV format, as summarized in Table 1.
Table 1: features description of malicious and benign websites dataset
COLUMN NAME description
URL the anonymous identification of the URL analyzed in the study
URL_LENGTH the number of characters in the URL
NUMBER_SPECIAL_CHARACTERS the number of special characters identified in the URL, such as /, %, #, &, =
CHARSET the character encoding standard (also known as the character set)
SERVER the operating system of the server obtained from the packet response.
CONTENT_LENGTH the content size of the HTTP header
WHOIS_COUNTRY the country of the server
WHOIS_STATEPRO the state of the country of the server (if known)
WHOIS_REGDATE the server date and time
WHOIS_UPDATED_DATE the last update of the server
TCP_CONVERSATION_EXCHANGE the number of TCP packets exchanged between the server and our
honeypot client
DIST_REMOTE_TCP_PORT the number of the ports detected and different to TCP
REMOTE_IPS the total number of IPs connected to the honeypot
APP_BYTES the number of bytes transferred
SOURCE_APP_PACKETS packets sent from the honeypot to the server
REMOTE_APP_PACKETS packets received from the server
APP_PACKETS the total number of IP packets generated during the communication between the honeypot and the server
DNS_QUERY_TIMES the number of DNS packets generated during the communication between the honeypot and the server
TYPE 1 is for malicious websites and 0 is for benign websites
Problem Statement
This is an individual assessment task. Each student is required to submit a report of approximately 1000 words along with exhibits to support findings with respect to the provided malicious and benign websites. This report should consist of:
• Literature review in malicious websites detection
• Construction of datasets, data pre-processing and features
• Workflow of malicious website detection that describes the process of conducting malicious website detection
• Technical findings of classification results
• Justified discussion of the performance evaluation outcomes for different classifiers
To demonstrate your achievement of these goals, you must write a report of at least 1,000 words (1,500 words maximum and excluding references). Your report should consist of the following chapters:
1. A proper title which matches the contents of your report. (1 points)
2. Your name and student number in the author line. (1 points)
3. An executive summary which summarizes your findings. (You may find hints on writing good executive summaries from (2 points)
4. An introduction chapter which lists the classification algorithms of your choice (at least 3 algorithms), the data used for classification, the performance evaluation metrics (at least 3 evaluation metrics), the summary of your findings, and the organization of the rest of your report. (2 points)
5. A literature review chapter which surveys the latest techniques from academic research papers regarding the malicious website detection. Besides machine learning techniques, you need to include at least another two approaches to detect malicious websites. You are advised to identify and cite at least one paper published by ACM and IEEE journals or conference proceedings. In addition, the aim of this part of the report is to demonstrate deep and thorough understanding of the existing body of knowledge encompassing multiple classification techniques for security data analytics, specifically, your argument should explain why machine learning algorithms should be used rather than human readers. (Please read through the hints on this web page before writing this chapter (4 points)
6. A chapter describes the dataset that you used for malicious website detection, which includes the construction of datasets, data pre-processing, and the features identified for classification. (4 points)
7. A methodology chapter that depicts the workflow of malicious website detection that describes the process of conducting malicious website detection. Figure 1 gives the example of Twitter Spam Detection workflow. (4 points)
Figure 1: Twitter Spam Detection workflow
8. A technical demonstration chapter which consists of fully explained screenshots when your experiments were conducted in R. That is, you should explain each step of the procedure of classification, and the performance results for your classifiers. You should use at least 3 machine learning algorithms. (4 points)
9. A performance evaluation chapter which evaluates the performance of classifiers. You should analyse each classifier’s performance with respect to the performance metrics of your choice. In addition, you should compare the performance results in terms of evaluation metrics, e.g., accuracy, false positive, recall, F-measure, speed and so on, for the selected classifiers and datasets. (4 points)
10. A conclusions chapter which summarizes major findings of the study (You should use at least 3 evaluation metrics to evaluate the performance of classifiers and compare the performance of different classifiers. You can demonstrate your experiment results in the form of table and plots), discusses whether the results match your hypotheses prior to the experiments and recommends the best performing classification algorithm. (2 points)
11. A bibliography list of all cited papers and other resources. You must use in-text citations in Harvard style and each citation must correspond to a bibliography entry. There must be no bibliography entries that are not cited in the report. (You should know the contents from this page (2 points)
