Web Applications Security Maintenance

The Manager's Guide to Web Application Security is a concise, information-packed guide to application security risks every organization faces, written in plain language, with guidance on how to deal with those issues quickly and effectively. Often, security vulnerabilities are difficult to understand and quantify because they are the result of intricate programming deficiencies and highly technical issues. Author and noted industry expert Ron Lepofsky breaks down the technical barrier and identifies many real-world examples of security vulnerabilities commonly found by IT security auditors, translates them into business risks with identifiable consequences, and provides practical guidance about mitigating them. The Manager's Guide to Web Application Security describes how to fix and prevent these vulnerabilities in easy-to-understand discussions of vulnerability classes and their remediation. For easy reference, the information is also presented schematically in Excel spreadsheets available to readers for free download from the publisher’s digital annex. The book is current, concise, and to the point—which is to help managers cut through the technical jargon and make the business decisions required to find, fix, and prevent serious vulnerabilities.

While many resources for network and IT security are available, detailed knowledge regarding modern web application security has been lacking—until now. This practical guide provides both offensive and defensive security concepts that software engineers can easily learn and apply. Andrew Hoffman, a senior security engineer at Salesforce, introduces three pillars of web application security: recon, offense, and defense. You’ll learn methods for effectively researching and analyzing modern web applications—including those you don’t have direct access to. You’ll also learn how to break into web applications using the latest hacking techniques. Finally, you’ll learn how to develop mitigations for use in your own web applications to protect against hackers. Explore common vulnerabilities plaguing today's web applications Learn essential hacking techniques attackers use to exploit applications Map and document web applications for which you don’t have direct access Develop and deploy customized exploits that can bypass common defenses Develop and deploy mitigations to protect your applications against hackers Integrate secure coding best practices into your development lifecycle Get practical tips to help you improve the overall security of your web applications

This expert guide describes a systematic, task-based approach to security that can be applied to both new and existing applications. It addresses security considerations at the network, host, and application layers for each physical tier—Web server, remote application server, and database server—detailing the security configurations and countermeasures that can help mitigate risks. The information is organized into sections that correspond to both the product life cycle and the roles involved, making it easy for architects, designers, and developers to find the answers they need. All PATTERNS & PRACTICES guides are reviewed and approved by Microsoft engineering teams, consultants, partners, and customers—delivering accurate, real-world information that’s been technically validated and tested.

Essay from the year 2011 in the subject Information Management, grade: B, The University of Chicago, language: English, abstract: As the world continues to enjoy the reliability of web-based applications, security of such applications is becoming an increasingly vital concern. Currently, virtually all sectors are implementing some form of internet-based programs. The World Wide Web has significantly led to desirable expansion in business, healthcare, government and social services (Lee, Shieh & Tygar, 2005, p.184). However, the number of internet attacks has equally increased in the recent past. Hackers have become more adept in writing malicious codes to counter the conventional software codes developed by software vendors. The emergence of various types of vulnerabilities and generation of malicious codes on the internet platform has affected service provision in many sectors. The healthcare field is a particularly sensitive area where privacy and confidentiality of information are immensely important. Storage, transmission and implementation of health-related data and information are some of the processes which require secure online platforms. As such, it is very important to provide security in web applications used in the health sector. This paper explores the impacts of web application security in e-health. Provision of integral healthcare in the modern medical profession has taken a new direction with regards to storage of clinical data and patients’ records (Chryssanthou & Apostolakis & Varlamis, 2010, p.3). In order to achieve a shared healthcare paradigm, implementation of web-based applications has become inevitable. Electronic health records (EHRs) have become a common buzzword in healthcare issues and facilities. The advent of EHRs has reliably replaced paperwork in medical informatics (Chryssanthou & Apostolakis & Varlamis, 2010, p.3). The EHR can be designed as an online-hosted platform in which medical information, patients’ health records and clinical data are stored. Security policies and programs must be integrated during the structuring of the EHRs, due to a number of reasons which are related to availability, confidentiality, privacy and authenticity of data and information. Security in e-health services requires safe transmission of data to and from the EHRs (Chryssanthou & Apostolakis & Varlamis, 2010, p.3).

IIS provides the core services for hosting Web servers, Web applications, and Microsoft Windows SharePoint services. To learn how to manage Web applications running on IIS and perform advanced administration tasks, you need practical hands-on advice from an expert who has years of experience working with IIS. William Stanek is such an expert. By reading this book and working step by step through the essential tasks discussed, you can learn to: Manage ISAPI and CGI applications, Configure ASP, ASP.NET, and .NET, Framework settings, Create and configure custom IIS applications, Customize settings for application pools, Start, stop, and recycle worker processes, Maintain application health and performance, Enhance Web server security and permissions, Configure handler mappings and authentication, Install and use Active Directory Certificate Services, Monitor and optimize IIS performance, Manage IIS backups and metabase configurations. This book is designed for anyone who wants to learn how to manage Web applications and perform advanced administration of IIS 7.0 and IIS 7.5. Inside, you'll find comprehensive overviews, step-by-step procedures, frequently used tasks, documented examples, and much more. One of the goals is to keep the content so concise that the book remains compact and easy to navigate while at the same time ensuring that the book is packed with as much information as possible--making it a valuable resource.

Academic Paper from the year 2018 in the subject Computer Science - IT-Security, grade: 10, , course: Master thesis, language: English, abstract: Modern web applications have higher user expectations and greater demands than ever before. The security of these applications is no longer optional; it has become an absolute necessity. Web applications contain vulnerabilities, which may lead to serious security flaws such as stealing of confidential information. To protect against security flaws, it is important to understand the detailed steps of attacks and the pros and cons of existing possible solutions. The goal of this paper is to research modern web application security flaws and vulnerabilities. It then describes steps by steps possible approaches to mitigate them.

Web-Application have been widely accepted by the organization be it in private, public or government sector and form the main part of any e-commerce business on the internet. However with the widespread of web-application, the threats related to the web-application have also emerged. Web-application transmit substantial amount of critical data such as password or credit card information etc. and this data should be protected from an attacker. There has been huge number of attacks on the web-application such as ‘SQL Injection’, ‘Cross-Site Scripting’, ‘Http Response Splitting’ in recent years and it is one of the main concerns in both the software developer and security professional community.This projects aims to explore how security can be incorporated by using security pattern in web-application and how effective it is in addressing the security problems of web-application.
