Thinking About Firewalls
نویسنده
چکیده
Many companies connect to the Internet, guarded by "firewalls" designed to prevent unauthorized access to their private networks. Despite this general goal, many firewalls fall widely apart on a continuum between ease of use and security. This paper attempts to describe some of the background and tradeoffs in designing firewalls. A vocabulary for firewalls and their components is offered, to provide a common ground for discussion.

A graph theoretic model for hardware-based firewalls
Firewalls offer a protection for private networks against external attacks. However, Configuring firewalls is a difficult task. The reason in that the effects of a firewall configuration cannot be easily seen during the configuration time. As a result, errors and loopholes in firewall configurations, if exist are discovered only after they actually happen at the execution time. In this paper, w...
متن کاملA Survey on Security Issues in Firewalls: A New Approach for Classifying Firewall Vulnerabilities
Along with the increasing growth of computer networks, security threats multiplies and accordingly improving and enhancing the network security devices and methods become a necessity. Firewalls as the first line of defense have irrefutable importance in securing a network; therefore improvement in this technology ensures higher level of security in computer networks. Any improvement or novel id...
متن کاملBypassing Firewalls: Tools and Techniques
This paper highlights a very important problem with network perimeter firewalls. The threat discussed is not exactly new, but neither is it widely recognised— even amongst network security professionals. Most commercial firewalls claim to be application layer devices, but they derive very little useful information about the context of the application traffic that passes through them. Malicious ...
متن کاملA security study of the Internet : an analysis of firewall behavior and anonymous DNS
Hosts connected to the Internet are exposed to a wide array of attacks. Multiple methods are used to limit and impede attacks. This paper looks at how and if some of these methods are deployed on the Internet. The most common method employed is to limit network access to hosts using firewalls. What percentage of IP addresses are behind firewalls? What do these firewalls block and allow? What co...
متن کاملWhat Do Firewalls Protect? An Empirical Study of Firewalls, Vulnerabilities, and Attacks
Firewalls are a cornerstone of how sites implement “defense in depth.” Many security policies assume that outside attackers must first penetrate a firewall configured to block their access. This paper examines what firewalls protect against, and whether those protections are sufficient to warrant placing the current level of trust in firewalls.
