3.1 Exploit XSS Vulnerabilities
The standard javascript code to test for XSS vulnerabilities is : alert(“Hacked”). The script is entered on the register page in the email address input. The script must be entered in the email input when the user registers. The attack is amended with the SQL injection added at the end. The standard javascript attack works but the SQL injection at the end add a value in the field. alert(“Hacked”) ' or '1'='1' -- '.
The script allows the javascript to be embeded in the source code and the pop-up to show. The SQL injection allows the email field to be filled with a value of " ' OR 1=1 -- ". The original code failed because no value was entered for the email address. The registered username and password for this example is Tom. After registering with the XSS code in the email address field, the user logs in and the javascript pop-up with “Hacked ” appears. (See Figure 3.1-1 below).
Figure 3.1-1 Javascript pop-up shows XSS.
After selecting OK on the javascript pop-up the Member Area displays the username and the email address of " ' OR 1=1 -- ". (See Figure 3.1-2 below).
Figure 3.1-2 Email address displays SQL login.
The javascript code is embeded in the source code on the Member Area page.
(See Figure 3.1-3 below).

The javascript code can be amended by replacing “Hacked ” with document.cookie which captures the session ID. (See Figure 3.1-4 below).

The first fix attempted to prevent SQL injection is to escape all user input. Escaping all user input prevents SQL injection but not in every in...

6. Conclusion
The purpose of this project was to identify vulnerabilities in source code, then attack the vulnerabilities, and finally, fix the errors to make the code secure. The number of potential vulnerabilities that exist in a small web application are numerous and wide ranging. Based on these findings it's pertinent to say that copious security vulnerabilities exist in source code and on the client side of web appications. The problem is programmers are not taught to code securely because security has only become a real issue in recent times. Many of the errors in software code are trivial to fix. It may be impossible and financially infeasible to fix all of the code in the world, but with better coding practices the potential security risks can be reduced.
However, I feel users had a different vision/perspective on security mechanisms and they trusted each other during those times and did not have to worry about protecting their information (this is how exactly, one person’s ignorance becomes another’s person’s - hacker, here bliss). This book helps us to understand the vulnerabilities; its impacts and why it is important to address/ fix those holes.
A developer for Aim Higher College is creating a Web server form for submission of calendar events to the College’s event calendar. First let’s look into the type of the attacks the web server would be vulnerable to. The website server can fall into the wrong hands and face xss attacks where the attacker steals important information of the client and reduces the speed of the network and also sends large volume...

These attackers have proven to be a very successful way for a criminal to get inside of many organizations. Social engineer may call an organization’s for asking help and pretending them to be an employee who has forgotten their password. Help desk staff will frequently assist this helpless to log on remotely and reset their password for them, without ever verifying their identity. Different mail attachments and web links are being very popular among social engineering.
This paper is being furnished to provide the CIO with a technology evaluation of vulnerability scanning. The information provided will ensure that the CIO has the required information to make the best decision in regards to this technology. This paper provides a brief understanding of vulnerability scanning, its many forms, the types of scanners available, the advantages and disadvantages, and the costs involved.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what

Malicious code is a real danger to modern systems. Most systems nowadays do not work in isolation; they are more likely to be connected to other systems and sometimes they can even be dependent on them. Therefore an attack on one of the systems in the network is a potential attacking attempt to any other systems, with which it is interacting. Therefore, it is inevitable for any networked or Internet-connected computers to deal with malicious code attacks at some point. Businesses lose billions of dollars each year because of malicious code attacks. Responding to the attack and restoring all the data on the computers is a time-consuming and expensive task. It is a much better practice to try preventing it through organizing and maintaining effective defenses. However, it is important to keep in mind that there is no one general solution that can help to prevent all the attacks. Attackers are constantly looking for new ways to take advantage of systems’ vulnerabilities and find new ones. That’s why organizations have to not only defend themselves against existing attack methods, but also try to predict and prevent new attacking techniques. It means that computer and network security is a never-ending challenge and expense.

Another command added to this code will make it so that if the user enters the wrong password the code will send them to a site of the scripts designers choice. Java Script is also a popular language for making simple interactive games like bridge and peg games. These codes can provide hours of fun! Java Script is used mainly on pages that need to allow users to enter information or choose from options on the page.
... 50minutes of down time. This attack was impressive on both ends, it showed the hacker had great skill, but also showed the white hats working for Reddit do an amazing job.. There are several laws in most countries against hacking in this way, and the punishments are severe, but that doesn’t stop most hackers.
