...Web Server Application Attacks Brooks Gunn Professor Nyeanchi CIS 502 July 10, 2013 Web Server Application Attacks Many organizations have begun to use web applications instead of client/server or distributed applications. These applications has provided organizations with better network performance, lower cost of ownership, thinner clients, and a way for any user to access the application. We applications significantly reduce the number of software programs that must be installed and maintained in end user workstations (Gregory 2010). Web applications are becoming a primary target for cyber criminals and hackers. They have become major targets because of the enormous amounts of data being shared through these applications and they are so often used to manage valuable information. Some criminals simply just want vandalize and cause harm to operations. There are several different types of web application attacks. Directory traversal, buffer overflows, and SQL injections are three of the more common attacks. One of the most common attacks on web based applications is directory traversal. This attack’s main purpose is the have an application access a computer file that is not intended to be accessible. It is a form of HTTP exploit in which the hacker will use the software on a Web server to access data in a directory other than the server’s root directory. The hacker could possibly execute commands...

Khilar Submitted byDinesh Shende Roll No-212CS2102 M.Tech(1st year) Directions for Web and E-Commerce Applications Security Abstract: This paper provides directions for web and e-commerce applications security. In particular, access control policies, workflow security, XML security and federated database security issues pertaining to the web and e-commerce applications are discussed. These security measures must be implemented so that they do not inhibit or dissuade the intended e-commerce operation. This paper will discuss pertinent network and computer security issues and will present some of the threats to e-commerce and customer privacy. These threats originate from both hackers as well as the e-commerce site itself. Another threat may originate at ostensibly friendly companies such as DoubleClick, MemberWorks and similar firms that collect customer information and route it to other firms. Much of this transaction information is able to be associated with a specific person making these seemingly friendly actions potential threats to consumer privacy. Many of the issues and countermeasure discussed here come from experiences derived with consulting with clients on how to maintain secure e-commerce facilities. These methods and techniques can be useful in a variety of client and server...

...Unit 9 Discussion 1: Business anywhere-Security and the mobile User The need for employees to check their emails and keep in touch with customers is becoming more and more of a frequent need to keep business moving. National Express Packaging’s employees are in need of using end point devices such as mobile phones, tablets, laptops and USB devices to access company information. There have been various requests upon this subject per department and it is necessary to provide specific end point devices to the various departments only depending on what they need. The sales team only needs to check email and their work contacts frequently. A mobile device such as a cell phone can be used in this case for this department. The sales employees will be able to check their email at any time providing they have an encrypted connection to go along with their email. This device can be provided by the company or they can use their own device but a policy must be in place if the personal mobile device will be used. The Service team needs to be able to check online for packaging rates and be able to chat with users. In this department, it is best to use a tablet in the case that the tablet will have internet access and will use a specific application to be able to chat with customers. For the IT department, users should have the ability to use a laptop as they will be doing more rigorous activities. The laptop must be secured and hardened to prevent remote attacks.

...critical to perform a penetration test on a Web application and a Web server prior to production implementation? To make sure no attackers can penetrate your web application before the Web App goes live. It is critical to perform a penetration test on a Web application because the Web application is running on an Application Server or a Web Server, if an attacker is able to access the application code for how the database is called, it may be able to retrieve information about the database (name, attributes, IP address, etc.) and or access the Web Server and attempt a DoS attack. If a Web form cannot handle the unexpected data and fails to return the expected outcome. You have uncovered a vulnerability in this form; penetration testing in this area help IT security identify the vulnerabilities a Web Application may have. 2. What is a cross-site scripting attack? The goal of an XSS attack is see if the Web Application allows the attacker to have administrative read/write access to the functionality of the Web Application. This attack is a type of computer security vulnerability typically found inweb applications that enables attacks to inject client-side script into web pages viewed and accessed by other users. 3. What is a reflective cross-site scripting attack? If the attacker can type a script in a text field and the script alters or creates a pop-up display, the attacker can use these windows to navigate users off the Web Application pages and to constructed pages with malicious...

...Deploying Application Firewall in Defense in Depth Principle Abstract Information security should be a priority for businesses, especially when they are increasingly involved in electronic commerce. With the understanding that securing an operating system successfully requires taking a systematic and comprehensive approach, security practitioners have recommended a layered approach called defense-in-depth. The cost and complexity of deploying multiple security technologies has prevented many organizations from achieving their information security goal. In view of these constraints and in compliance with recent with recent corporate and industry regulations like Sarbanes-Oxley Act and Payment Card Industry Data Security Standard, businesses now deploy application firewalls as security measures. Based on the foregoing, the author has recommended the use of application firewalls as a single platform for achieving layered security through network protection, application protection and data protection. This paper commences by examining the defense in depth theory and the types of application firewall and the author concludes by citing the Institute for Computing Applications (IAC) of the Italian National Research Council (CNR) as an example of an organization which engaged application firewalls in resolving its network security problem. Research Analysis/ Body The development of Information security is of paramount importance to organizations that have online presence...

...Lab Five Executive Summary A security test is a method of evaluating the security of a computer system or network by methodically validating and verifying the effectiveness of application security controls. A web application security test focuses only on evaluating the security of a web application. The process involves an active analysis of the application for any weaknesses, technical flaws, or vulnerabilities. Any security issues that are found will be presented to the system owner, together with an assessment of the impact, a proposal for mitigation or a technical solution (Open Web Application Security Project [OWASP], 2014a). Vulnerability is a flaw or weakness in a system's design, implementation, operation or management that could be exploited to compromise the system's security objectives. A threat is anything such as a malicious external attacker, an internal user, or a system instability that can harm the owner’s assets by an application or resource of value, such as data in a database or in the file system by exploiting vulnerabilities. A test is an action to demonstrate that an application meets the security requirements of its stakeholders (OWASP, 2014a). Test to Be Performed The first phase in security assessment is focused on collecting as much information as possible about a target application. Information Gathering is the most critical step of an application security test. The security test should endeavor to test as much of the code base as possible...

...with Web Applications Web applications allow visitors access to the most critical resources of a web site, the web server and the database server. Like any software, developers of web applications spend a great deal of time on features and functionality and dedicate very little time to security. Its not that developers don’t care about security, nothing could be further from the truth. The reason so little time is spent on security is often due to a lack of understanding of security on the part of the developer or a lack of time dedicated to security on the part of the project manager. For whatever reason, applications are often riddled with vulnerabilities that are used by attackers to gain access to either the web server or the database server. From there any number of things can happen. They can: •Deface a web site •Insert spam links directing visitors to another site •Insert malicious code that installs itself onto a visitor’s computer •Insert malicious code that steals session IDs (cookies) •Steal visitor information and browsing habits •Steal account information •Steal information stored in the database •Access restricted content •And much more… Preventing Web Application Attacks With dotDefender web application firewall you can avoid many different threats to web applications because dotDefender inspects your HTTP traffic and checks their packets against rules such as to allow or deny protocols, ports, or IP addresses to stop web applications from being...

...Web Server Application Attacks Christopher Jones Theories of Security Management Dr. Alaba Oluyomi Most web attacks are executed by several different methods to interrupt the functions of web servers. Web applications incorporate several applications to make it work properly. The web administrator must monitor the databases, extended markup languages, and script interpreters to stay ahead of hackers. All website that are running on a web server are prone to compromise, even though they are coded. Attackers take advantage of vulnerabilities of the web server. Attacker takes advantage of vulnerabilities within the implementation of TCP/IP protocol suites. With the slow reactions to correct these deficiencies, attackers are shifting to the application layers and mainly the web. This is in part caused by most companies open their firewall systems to web traffic. Most of the attacks are broad, and comes in many versions that fall into similar categories. Companies are making their web servers more secure, so attacks are moving to the vulnerability of web application flaws. Below are types of attacks on a web server 1 Web application vulnerabilities can be categorized as follows; Web server vulnerabilities, Manipulation of URLs, Exploitation of weaknesses in session identifiers and authentication systems, HTML code Injection and Cross-Site Scripting, and SQL Injection. SQL injection is a technique often used to attack data driven applications. This is done...

...Web Server Security and Database Server Security Databases involve distributed updates and queries, while supporting confidentiality, integrity, availability, and privacy (Goodrich, & Tamassia, 2011). This entails robust access control as well as tools for detection and recovering from errors (2011). When database information is masked, there is still a possibility of an attacker garnishing sensitive data from additional database information that is available, this can be achieved and called an inference attack (2011). For databases, strategies have been designed to mitigate against inference attacks. Cell suppression is a technique used to combat an inference attack, by removing various cells in a database, and are left blank for published versions (2011). The objective is to suppress the critical cells that have relatively important information in them from being obtained in an attack (2011). Another strategy is called Generalization, and this involves replacing published versions of database information with general values (2011). Such as stating a specific date of birth with a range of years, thus a person born in 1990 could be generalized as a range 1985-1992. The critical values are intertwined with the actual values, so they are less discernable in an inference attack (2011). A Noise Addition technique can also be utilized. This requires adding randomized values to real values in a published database (2011). This provides “noise” for all the records of the...

...Magic Quadrant for Web Application Firewalls Page 1 sur 13 Magic Quadrant for Web Application Firewalls 17 June 2014 ID:G00259365 Analyst(s): Jeremy D'Hoinne, Adam Hils, Greg Young, Joseph Feiman VIEW SUMMARY The WAF market is growing quickly from a small base; it is composed of pure players, application delivery controller vendors, cloud service providers and network security vendors. Buyers should evaluate how WAFs can provide high security, minimize false positives and sustain performance. STRATEGIC PLANNING ASSUMPTIONS At the end of 2018, less than 20% of enterprises will rely only on firewalls or intrusion prevention systems to protect their Web applications — down from 40% today. By year-end 2020, more than 50% of public Web applications protected by a WAF will use WAFs delivered as a cloud service or Internet-hosted virtual appliance — up from less than 10% today. Market Definition/Description The Web application firewall (WAF) market is defined by a customer's need to protect internal and public Web applications when they are deployed locally (on-premises) or remotely (hosted, "cloud" or "as a service"). WAFs are deployed in front of Web servers to protect Web applications against hackers' attacks, to monitor access to Web applications, and to collect access logs for compliance/auditing and analytics. WAFs are most often deployed in-line, as a reverse proxy, because historically it was the only way to perform some in-depth inspections. Other deployment modes...
