Cyber security is the science behind protecting the company's infrastructure, including employees' computers, their network, the servers where they host the web application, and the database of users' information or any sensitive information. They use some tools to assess the security of their infrastructure and to discover new vulnerabilities. Everyone can share his classes, even amateurs who know using the tools but do not understand the concepts behind these vulnerabilities and how they get exploited. Still, I’ve found a course created by experts in this domain from the University of Maryland called Cybersecurity Specialization offered on the Coursera platform. Is Cybersecurity Specialization on Coursera worth it? Now, let's review this awesome CyberSecurity course and specialization on three main parameters. Instructor quality, which mean how experienced and expert instructor are teaching these courses, second and most important course structure and content quality, which mean which topics are covered and how well they are covered, and there and most important what peoples are saying about these courses, particularly those who have joined and completed this course. This first section of cyber security will focus on building secure systems. You will learn about Human-Computer Interaction, the science that studies the use of computer technology and the usability, tasks, and cognitive models. Then move to the design methodology of securing systems, SSL warning, qualitative evaluation, and running controlled experiments. Next, you will learn about some strategies for securing interaction design and understand the usable security guidelines, authority guidelines, authorization & communication guidelines. You will also learn about usable authentication, two-factor authentication that adds an extra layer of security for users, biometric authentication. Finally, understand the functional privacy basics and privacy policies.

This specification defines an API for storing data in databases that can be queried using a variant of SQL. Beware. This specification is no longer in active maintenance and the Web Applications Working Group does not intend to maintain it further. This section describes the status of this document at the time of its publication. Other documents may supersede this document. This document is the 18 November 2010 Working Group Note of Web SQL Database. Publication as a Working Group Note does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress. The W3C Web Applications Working Group is the W3C working group responsible for this document.

This document was on the W3C Recommendation track but specification work has stopped. The specification reached an impasse: all interested implementors have used the same SQL backend (Sqlite), but we need multiple independent implementations to proceed along a standardisation path. The Web Applications Working Group continues work on two other storage-related specifications: Web Storage and Indexed Database API. Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways. Vendors interested in implementing this specification should join the aforementioned mailing lists and take part in the discussions. All feedback is welcome. The latest stable version of the editor's draft of this specification is always available on the W3C CVS server. This specification is automatically generated from the corresponding section in the HTML5 specification's source document, as hosted in the WHATWG Subversion repository.

This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. First, a function prepareDatabase() is defined. This function returns a handle to the database, first creating the database if necessary. Sometimes, there might be an arbitrary number of variables to substitute in. All diagrams, examples, and notes in this specification are non-normative, as are all sections explicitly marked non-normative. Everything else in this specification is normative.The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in the normative parts of this document are to be interpreted as described in RFC2119. For readability, these words do not appear in all uppercase letters in this specification. Requirements phrased in the imperative as part of algorithms (such as "strip any leading space characters" or "return false and abort these steps") are to be interpreted with the meaning of the key word ("must", "should", "may", etc) used in introducing the algorithm.Some conformance requirements are phrased as requirements on attributes, methods or objects.
