To achieve the goals of using EMR, attaining security and privacy Keywords: is extremely important. This study aims to propose a web framework with inbuilt security features that will prevent the common security vulnerabilities CodeIgniter security in the electronic medical record. The security features of the three most CSRF popular and powerful PHP frameworks Laravel, CodeIgniter, and Symfony EMR security issues were reviewed and compared.

This chapter will walk you through some of the most important concepts behind Symfony2 and explain how you can get started quickly by showing you a simple project in action. If you’ve used a web framework before, you should feel right at home with Symfony2. If not, welcome to a whole new way of developing web applications! Tip: Want to learn why and when you need to use a framework? Read the “Symfony in 5 minutes” document. Downloading Symfony2 First, check that you have installed and configured a Web server (such as Apache) with PHP 5.3.2 or higher. Ready? Start by downloading the “Symfony2 Standard Edition”, a Symfony distribution that is preconfigured for the most common use cases and also contains some code that demonstrates how to use Symfony2 (get the archive with the vendors included to get started even faster). After unpacking the archive under your web server root directory, you should have a Symfony/ directory that looks like this: www/ <- your web root directory Symfony/ <- the unpacked archive app/ cache/ config/ logs/ Resources/ bin/ src/ Acme/ DemoBundle/ Controller/ Resources/ ..

Web applications are no exception since modern HTML5 surface. Web applications are vulnerable to a wide range standards and the ever-increasing capabilities of JavaScript are of client-side and server-side attacks including Cross-Site utilized to build rich web applications, often subsuming the Scripting [4, 47, 72], Cross-Site Request Forgery [3, 33, 46], need for traditional desktop applications. One possible way of Remote Code Execution [18], SQL injection [19,41], and timing handling this increased complexity is through the process of attacks [35,40]. All of these attacks have been abused numerous software debloating, i.e., the removal not only of dead code but times to compromise web servers, steal user data, move laterally also of code corresponding to features that a specific set of users behind a company’s firewall, and infect users with malware and do not require. Even though debloating has been successfully cryptojacking scripts [43,49,74]. applied on operating systems, libraries, and compiled programs, its applicability on web applications has not yet been investigated.

  • Comparison of Performance Between Raw SQL and Eloquent ORM in Laravel
    Comparison of performance between Raw SQL and Eloquent ORM in Laravel Faculty of Computing i Blekinge Institute of Technology SE-371 79 Karlskrona Sweden Contact Information: Author(s): Ishaq Jound E-mail: [email protected] Hamed Halimi E-mail: [email protected] University advisor: Mikael Svahnberg Faculty of Computing Faculty of Computing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE-371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 i ABSTRACT Context. PHP framework Laravel offers three techniques to interact with databases, Eloquent ORM, Query builder and Raw SQL. It is important to select the right database technique when developing a web application because there are pros and cons with each approach. Objectives. In this thesis we will measure the performance of Raw SQL and Eloquent ORM, there is little research on which technique is faster. Intuitively, Raw SQL should be faster than Eloquent ORM, but exactly how much faster needs to be researched. Methods. To measure the performance of both techniques, we developed a blog application and we ran database operations select, insert and update in both techniques. Conclusions. Results indicated that overall Raw SQL performed better than Eloquent ORM in our database operations. There was a noticeable difference of average response time between Raw SQL and Eloquent ORM in all database operations. We can conclude that Eloquent ORM is good for building small to medium sized applications, where simple CRUD operations are used for the small amount of data. Typically for tasks like inserting a single row into a database or retrieving few rows from the database.
