Today we live in a flood of web sites and access numerous websites through the Internet to obtain various information. However, unless the security of the Web site is secured, Web site security can not be secured from various malicious attacks. Hacking attacks, which exploit Web site security vulnerabilities for various reasons, such as financial and political purposes, are increasing. Various attack techniques such as SQL-injection, Cross-Site Scripting(XSS), and Drive-By-Download are being used, and the technology is also evolving. In order to defend against these various hacking attacks, it is necessary to remove the vulnerabilities from the development stage of the website, but it is not possible due to various problems such as time and cost. In order to compensate for this, it is important to identify vulnerabilities in Web sites through web vulnerability checking and take action. In this paper, we investigate web vulnerabilities and diagnostic techniques and try to understand the priorities of vulnerabilities in the development stage according to the actual status of each case through cases of actual web vulnerability diagnosis.

The most important technology in the electronic commerce based on Internet is to guarantee the security of trading information exchange. Many technologies are proposed as a standard to support this security problem. One of them is an XML (eXtensible Markup Language). This is used in various applications as the document standard for electronic commerce system. The XML security has become very important topic. In this paper an XML security model for web services based electronic commerce system to guarantee the secure exchange of trading information. To accomplish the security of XML, the differences of XML signature, XML encryption and XML key management scheme respect to the conventional system should be provided. The new architecture is proposed based on unique characteristics of XML. Especially the method to integrate the process management system need to the electronic commerce is proposed.

Web-based health information provides a lot of conveniences, however the security vulnerabilities that appear in the network environment without the risk of exposure in the use of information are growing. Web-based medical information security issues when accessing only the technology advances, without attempting to seek a safe methodology are to increase the threat element. So it is required. to take advantage of web-based information security measures as a web-based access control security mechanism-based design. This paper is based on software architecture, design, ideas and health information systems were designed based on access control security mechanism. The methodologies are to derive a new design procedure, to design architecture and algorithms that make the mechanism functio n. To accomplish this goal, web-based access control for multiple patient information architecture infrastructures is needed. For this software framework to derive features that make the mechanism was derived based on the structure. The proposed system utilizes medical information, medical information when designing an application user retrieves data in real time, while ensuring integration of encrypted information under the access control algorithms, ensuring the safety management system design.

World Wide Web(WWW) has a lot of useful charaters. Easiness of use, multi-media data supporting and interactive communication capability are typical reasons why people want to use WWW. But because WWW is based on Internet, it has some security problems which originate in plain format data transmission on physical transmission line. The unique solution fer this problems is data encryption. Since theoritically proved encryption algorithms ensure data confidentiality, a unauthorized user can not know what is transmitted on network. In this paper, we propose a cryptography system which uses public key system. In detail, our public key based web security mechanism is using PGP module. PGP is a e-mail security system implemented by Phil Zimmermann. The basic idea of our propose is data encryption and integrity checking for all data which is transmitted on Web. To implement these facilities, we. use netscape browser extension technology, plug-in. Through these technology, security mechanisms are added on netscape browser.

This paper suggested a web based error manager for societal security service. This is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share error applications. Our a web based error manager for societal security service enables user to share error objects through interaction awareness. This method has a file sharing, a window copy, a window overlay, or a window sharing. We implemented the web based error manager for societal security service so that the users participated in collaborative work may refer shared error objects as the same view to others.

In this paper, we propose a "Safe Web Using Scrapable Headless Browse" Because in a network separation environment for security, It does not allow the Internet. The reason is to physically block malicious code. Many accidents occurred, including the 3.20 hacking incident, personal information leakage at credit card companies, and the leakage of personal information at "Interpark"(Internet shopping mall). As a result, the separation of the network separate the Internet network from the internal network, that was made mandatory for public institutions, and the policy-introduction institution for network separation was expanded to the government, local governments and the financial sector. In terms of information security, network separation is an effective defense system. Because building a network that is not attacked from the outside, internal information can be kept safe. therefore, "the separation of the network" is inefficient. because it is important to use the Internet's information to search for it and to use it as data directly inside. Using a capture method using a Headless Web browser can solve these conflicting problems. We would like to suggest a way to protect both safety and efficiency.

The multi-tenancy and high scalability of the cloud have inspired businesses and organizations across various sectors to adopt and deploy cloud computing. Cloud computing provides cost-effective, reliable, and convenient access to pooled resources, including storage, servers, and networking. Cloud service models, SaaS, PaaS, and IaaS, enable organizations, developers, and end users to access resources, develop and deploy applications, and provide access to pooled computing infrastructure. Despite the benefits, cloud service models are vulnerable to multiple security and privacy attacks and threats. The SaaS layer is on top of the PaaS, and the IaaS is the bottom layer of the model. The software is hosted by a platform offered as a service through an infrastructure provided by a cloud computing provider. The Hypertext Transfer Protocol (HTTP) delivers cloud-based apps through a web browser. The stateless nature of HTTP facilitates session hijacking and related attacks. The Open Web Applications Security Project identifies web apps' most critical security risks as SQL injections, cross-site scripting, sensitive data leakage, lack of functional access control, and broken authentication. The systematic literature review reveals that data security, application-level security, and authentication are the primary security threats in the SaaS model. The recommended solutions to enhance security in SaaS include Elliptic-curve cryptography and Identity-based encryption. Integration and security challenges in PaaS and IaaS can be effectively addressed using well-defined APIs, implementing Service Level Agreements (SLAs), and standard syntax for cloud provisioning.
