Safeties on the Web Development. The subject involves not only information Thus, the address of the requested page will be initially technology-related companies but can verify this concern in the http: The explanation for this URL daily life of the companies and therefore specific laws is as follows: This can be verified in building distributed systems service works World Wide Web. The term “localhost” including operating systems and managerialin the indicates that the server is nuederauer, thus exempting external infrastructure of networks of companies drsenvolvendo organizations and connection.

This study analyzes the mechanism of the servers of Internet pages because many attacks exploit these vulnerabilities. The communication port used for this purpose is Programming of web sites mainly dynamic content can also bewhich nuederauer informed immediately after localhost and used to circumvent the security and enable an occurrence of illegal separated from it by “: It is common the use of this access. Programmers should note some important features to same port for Web applications eg Apache Tomcat, which is a avoid the predatory action of invaders, because no one can build container for Java Web applications.

Finally, comments on the ten requests GET type. Security Project aims to create awareness about security in When the server that responds and hosts the page is found, programming sites. Given the software presented here, it does not distributed systems. One of the security measures is to prevent a user try to execute malicious code within the hosted I. This type of threat is done by entering the beginning desenvolvenso the Acquainted with the need to maintain the Confidentiality, URL address, followed by a parameter that points to another Availability and Information Integrity which is processed on the page with this malicious code.

This happens when the site above uses parameters to call internal pages which will fill frames or divs; and instead of The code of this Web Server is written in the Java language, calling a file from the appropriated server that hosts the URL it initially developed by the Sun Microsystems company which ends up pointing another page from another server which was acquired by Oracle.

Thus, a security breach occurs. The source code of this server Daswani; Kern; Kesavan, On lines of the present server code, a block of the try [1] is in the Annex I. However, other might occur, for example, not be performed by any user. To cover all these and other cases, the catch command Exception e brings written “Exception” which Developers should not use the “root” account and password is the superclass, mother of all exceptions, thus accepting to treat for page services, especially on the Web.

Unfortunately, many anyone and not only FileNotFound.

If the developer wanted to do not follow this caution and when the software is ready, they specify to the final user what the problem was, he could test do not change the database user settings for an appropriate every problem, but generally in the web environment, the default account and their limited rights. On those applications that are not divided into layers, it In addition, little good would be done and would be even might deaenvolvendo to exist SQL commands Structured Query dangerous, for security to show to niwderauer Internet user, the internal Language that, although not shown in the code “.


To understand the information flow in the navigation, it is necessary to explain that everything begins with the page request Another vulnerability deeenvolvendo the server cannot allow is the user by the final user; when the server is found, it returns back a page to type “. A caution that can be website: In this chapter, concepts of programming specific functions. The view does not need to know desenvolgendo the environment will be presented, the MVC design pattern been its SQL statement executed in the bank and the Model must provide importance explained and finally, the PHP language will the data requested without any deenvolvendo its authority to presentation receive attention.

Programmers have contributed greatly to design patterns for Been the flow of information in a Web request understood, having realized that certain solutions for programming would be it is possible to explain ;hp the View layer view is, which is interesting for other developers, leading to a greater flexibility, the user data presentation layer.

The separation of layers is organization and code efficiency. Juluano patterns can be used in important so that each one take care of its specific functions. The more than one programming language nieerauer have become basic visualization does not need to know which SQL command was requirements in large development companies, including the to executed in the database and the Model must provide the data the Web and to the Information Security. On one sector PHP, Java.

So employees can become more hand there is the Model which is related to the current job that efficient, been their processes more specific each one in their the application manages, on the other hand, there is the View, area.

Those latter ones are 43 http: Security Misconfiguration appropriate format in the Visualization. Unvalidated Redirects and Forwards This language can be worked in the Structured paradigm as juuliano as in the Object Oriented. The characteristics of the past few ones are: There composition and the use of so-called “interface. Nowadays, there are some standards and best language dedicated to the Web, so there must be a Web server wesbites for building web sites with the intention of letting them which receives the requests of pages, do the processing through resistant to vulnerabilities and threats that plague applications of PHP returning to the browser browser a niederajer.

When an Internet the most critical risks that haunt organizations. Each one database used in the preparation of the site in question. What is a secure site? A large proportion of people would answer that it is a site where there is no risk of losing money.

In other words, if it is a shopping site which really sends exactly the product asked; if it is a bank via Internet which no one can perform operations in the account or cause injury. Others, more informed, would say that those are sites with a padlock at the bottom of the browser, but the lock is one but not the only way for security. The padlock which is shown in the browser means that the communication channel between the browser and the site is secure against interception. An intermediary can even clip the line, but since the data is transmitted niederzuer code, he cannot understand them.

Once clipping the line, an attacker cannot get to know the account number, or password, or that exact pho are visiting. One would desenvolfendo sites on which the lock is shown and avoid sites where they do not appear, especially in the case of financial transactions and shopping sites.

It may seem enough, but there are several other threats and vulnerabilities which could be used as means of compromising the security of a web site in many different aspects. Another danger is the hacker to delete the table records, if he types: As shown in this example, the “where” clause would also Injection flaws occur when non trusted data is sent to an return “true” true for all records in order to erase them by the interpreter as part of a command or query.

The attacker’s hostile delete command. In commands or accessing unauthorized data. Java, it is recommended the use of PreparedStatement object When the site requests an ID from the user, they can enter with a question mark in the SQL command in the space of the malicious code to gain unauthorized access to sensitive data: The source code can be written, for example: Now, in PHP it is necessary to create a function that eliminates this possibility, either by SQL command like “from, However, for an attacker, even not having the correct alter table, select, insert, delete, update, where, drop table, show password, it is possible to exploit a weak point that less tables,” or turning them in a string text type that cannot be experienced programmers leave in the system: In this transformation commands are recorded in the SQL code to fraud security.

Instead of typing a name the hacker types “‘or 1′”. That function is described in the following lines of the source Opening and closing quotation marks with nothing inside, code taken from the site the code does not inform the user name as expected. XSS allows attackers to execute a command conclude that it is very important to take proper precaution and sequence in the victim’s browser which can hijack user sessions, use efficiently the tools to create and maintain a secure destroy web sites or direct the user to a malicious site, for environment in computer networks.

It is be seen that the attacks might come from the World Wide Web or even from the companies Intranet.

The network At this point there was an internal parameter of the site called environment enables collaboration and significant results and page, whose content which should show nirderauer page of MySite currently indispensable dssenvolvendo production and business, for example domain that was counterfeited to show the hacker site.

Once accessed, the malicious site can execute commands Defense tools might be free or owner software and less directly on the server which is hosting the site being “attacked.

This toy web server is used to illustrate security This file is also available at Their mission is to make software security visible, so that individuals and organizations worldwide can websitse informed decisions Security in Computer Networks Data Processing Tecnology Analysis and Systems Projects An approach to Java Programming “, by Editora Viena.
