Automatic Retrieval of Updated Information Related to COVID-19 from Web Portals 1Prateek Raj, 2Chaman Kumar, 3Dr
European Journal of Molecular & Clinical Medicine ISSN 2515-8260 Volume 07, Issue 3, 2020 Automatic Retrieval of Updated Information Related to COVID-19 from Web Portals 1Prateek Raj, 2Chaman Kumar, 3Dr. Mukesh Rawat 1,2,3 Department of Computer Science and Engineering, Meerut Institute of Engineering and Technology, Meerut 250005, U.P, India Abstract In the world of social media, we are subjected to a constant overload of information. Of all the information we get, not everything is correct. It is advisable to rely on only reliable sources. Even if we stick to only reliable sources, we are unable to understand or make head or tail of all the information we get. Data about the number of people infected, the number of active cases and the number of people dead vary from one source to another. People usually use up a lot of effort and time to navigate through different websites to get better and accurate results. However, it takes lots of time and still leaves people skeptical. This study is based on web- scraping & web-crawlingapproach to get better and accurate results from six COVID-19 data web sources.The scraping script is programmed with Python library & crawlers operate with HTML tags while application architecture is programmed using Cascading style sheet(CSS) &Hypertext markup language(HTML). The scraped data is stored in a PostgreSQL database on Heroku server and the processed data is provided on the dashboard. Keywords:Web-scraping, Web-crawling, HTML, Data collection. I. INTRODUCTION The internet is wildly loaded with data and contents that are informative as well as accessible to anyone around the globe in various shape, size and extension like video, audio, text and image and number etc. -

CSCI 452 (Data Mining) Dr. Schwartz HTML Web Scraping 150 Pts
CSCI 452 (Data Mining) Dr. Schwartz HTML Web Scraping 150 pts Overview For this assignment, you'll be scraping the White House press briefings for President Obama's terms in the White House to see which countries have been mentioned and how often. We will use a mirrored image (originally so that we wouldn’t cause undue load on the White House servers, now because the data is historical). You will use Python 3 with the following libraries: • Beautiful Soup 4 (makes it easier to pull data out of HTML and XML documents) • Requests (for handling HTTP requests from python) • lxml (XML and HTML parser) We will use Wikipedia's list of sovereign states to identify the entities we will be counting, then we will download all of the press briefings and count how many times a country's name has been mentioned in the press briefings during President Obama's terms. Specification There will be a few distinct steps to this assignment. 1. Write a Python program to scrape the data from Wikipedia's list of sovereign states (link above). Note that there are some oddities in the table. In most cases, the title on the href (what comes up when you hover your mouse over the link) should work well. See "Korea, South" for example -- its title is "South Korea". In entries where there are arrows (see "Kosovo"), there is no title, and you will want to use the text from the link. These minor nuisances are very typical in data scraping, and you'll have to deal with them programmatically. -

Security Assessment Methodologies SENSEPOST SERVICES
Security Assessment Methodologies SENSEPOST SERVICES Security Assessment Methodologies 1. Introduction SensePost is an information security consultancy that provides security assessments, consulting, training and managed vulnerability scanning services to medium and large enterprises across the world. Through our labs we provide research and tools on emerging threats. As a result, strict methodologies exist to ensure that we remain at our peak and our reputation is protected. An information security assessment, as performed by anyone in our assessment team, is the process of determining how effective a company’s security posture is. This takes the form of a number of assessments and reviews, namely: - Extended Internet Footprint (ERP) Assessment - Infrastructure Assessment - Application Assessment - Source Code Review - Wi-Fi Assessment - SCADA Assessment 2. Security Testing Methodologies A number of security testing methodologies exist. These methodologies ensure that we are following a strict approach when testing. It prevents common vulnerabilities, or steps, from being overlooked and gives clients the confidence that we look at all aspects of their application/network during the assessment phase. Whilst we understand that new techniques do appear, and some approaches might be different amongst testers, they should form the basis of all assessments. 2.1 Extended Internet Footprint (ERP) Assessment The primary footprinting exercise is only as good as the data that is fed into it. For this purpose we have designed a comprehensive and -
Web Scraping)
שומן ושות ' משרד עורכי דין ונוטריון Schuman & Co. Law Offices Data Scraping On The Internet (Web Scraping) Introduction Web scraping , or data scraping, is an operation used for extracting data from websites. While web scraping can be done manually, the term typically refers to automated processes implemented using a web crawler or bot. It is a form of electronic copying, in which data is gathered and copied from the web for later analysis and use. There are methods that some websites use to prevent web scraping, such as detecting and disallowing bots from crawling their pages. In response, there are web scraping systems that rely on using techniques in DOM parsing, computer vision and natural language processing to simulate human browsing to enable gathering web page content for offline parsing. Potential Legal Violations Of Data Scraping In order to evaluate the risks of a data scraping business model, it is essential to recognize the potential legal violations that might transpire. Computer Fraud and Abuse Act (CFAA) The CFAA is a federal statute that imposes liability on someone who “intentionally accesses a computer without authorization or exceeds authorized access, and thereby obtains…information from any protected computer.” A determination of liability will typically focus on whether the data scraper has knowledge that the terms governing access to the website prohibit the data scraping activity. Breach of Contract If a user is bound by terms of service that clearly prohibit data scraping, and a user violates such terms, such a breach can be the basis for prohibiting the user's access and ability to scrape data. -

Guidelines on Minimum Standards for Developer Verification of Software
Guidelines on Minimum Standards for Developer Verification of Software Paul E. Black Barbara Guttman Vadim Okun Software and Systems Division Information Technology Laboratory July 2021 Abstract Executive Order (EO) 14028, Improving the Nation’s Cybersecurity, 12 May 2021, di- rects the National Institute of Standards and Technology (NIST) to recommend minimum standards for software testing within 60 days. This document describes eleven recommen- dations for software verification techniques as well as providing supplemental information about the techniques and references for further information. It recommends the following techniques: • Threat modeling to look for design-level security issues • Automated testing for consistency and to minimize human effort • Static code scanning to look for top bugs • Heuristic tools to look for possible hardcoded secrets • Use of built-in checks and protections • “Black box” test cases • Code-based structural test cases • Historical test cases • Fuzzing • Web app scanners, if applicable • Address included code (libraries, packages, services) The document does not address the totality of software verification, but instead recom- mends techniques that are broadly applicable and form the minimum standards. The document was developed by NIST in consultation with the National Security Agency. Additionally, we received input from numerous outside organizations through papers sub- mitted to a NIST workshop on the Executive Order held in early June, 2021 and discussion at the workshop as well as follow up with several of the submitters. Keywords software assurance; verification; testing; static analysis; fuzzing; code review; software security.

Advanced Threats: Keeping Cisos on Their Toes
WHITE PAPER Advanced Threats: Keeping CISOs on Their Toes Increasingly Complex Tactics by Adversaries Can Put Security Teams in Reactive Mode Executive Summary CISOs enjoy a greater status within organizations than ever before. But the reason for this new stature is that cybersecurity poses increasing and more direct threats to corporate profitability—and even survival. As if an expanding attack surface and growing security complexity were not enough, the threat landscape is evolving rapidly, requiring a strategic approach on the part of security teams. Advanced threats are steadily increasing in volume, velocity, and sophistication, rendering traditional, manual approaches to security useless. Specifically, reliance on a fragmented security architecture requires manual processes that reduce efficiency, “[A]dversarial automation is being expand risk, and endanger network performance. CISOs who rely on reactive, used to create and launch new tactical security approaches are simply unprepared to keep pace with the speed and attacks at such a rate and volume sophistication of the threat landscape. that every strain of malware must now be considered a zero day, Few executive roles have risen more in visibility and importance in the past decade than and every attack considered an that of the CISO. The job title has existed for a decade or less at many organizations— advanced persistent threat.”8 and the world’s first CISO was appointed just 25 years ago.1 Over the years, the responsibilities of the CISO have grown steadily,2 and CISOs find themselves in a more prominent position than ever before.3 A majority now report directly to the CEO or even to the board of directors,4 making them a peer to the CIO—leading a parallel organization focused solely on security.
