Abstract
Internet security is a branch of computer sciences often involving browser security, network security, applications and operating systems to keep the internet as a secure channel to exchange information by reducing the risk and attacks. There are a number of studies that have been conducted in this field resulting in the development of various security models to achieve internet security. However, periodic security reports and previous studies prove that the most secure systems are not immune from risk and much effort is needed to improve internet security. This paper proposed a simple security model to improve internet applications security and services protections, specified access control, cryptographic, cookies and session managements, defense programing practices, care for security from early stage on development life cycle, use hardware authentication techniques in access control, then propose cryptographic approach by mix MD5 with Based64, consider session and cookies types and ways to keep it secure. Additionally, these practices discussed the most important web security vulnerability and access control weakness and how to overcome such weaknesses, proposed an approach to measure, analyze and evaluate security project according to software quality standard ISO 25010 by using Likert scale, finally ended by case study. The effort of this paper represents a set of techniques and tips that should be applied within each web application development process to maintain its security.
