Similar content is readily available at other sites on the Internet that are not blocked in Singapore. In our testing, the OpenNet Initiative (ONI) 4found extremely minimal filtering of Internet content in Singapore, as only eight sites of 1,632 tested (.49%) were blocked: and The limited blocking that our testing revealed focuses on a few pornographic URLs and one site each in the categories of illegal drugs and fanatical religion. In addition, the MDA encourages, and each of Singapore's three primary Internet Service Providers offers, optional, filtered Internet access services that block additional sites for a minimal monthly fee. The Media Development Authority (MDA) claims to block only a symbolic list of 100 Web sites (primarily pornography) as a symbol of the state's disapproval of this content. 1Singapore's official position is that the state filters Internet content to promote social values and maintain national unity, 2with the goal of denying access to objectionable material, especially pornography and content encouraging ethnic or religious strife. The Republic of Singapore is an economic leader in Southeast Asia, with a vibrant information and communications technologies sector however, the state maintains strong formal and informal controls over the information to which its citizens have access.

Create a secure network and deploy a suitable firewall to limit the access to your computer and network.PDF Version 1. No matter which firewall you choose, ensure a proper configuration as any loophole can cause more damage to you than no firewall at all. This is all about the basic firewalls that are configured to protect a private network. Proxy Servers offers the best Internet experience and results in the network performance improvements. They provide a complete and protocol-aware security analysis for the protocols they support. Proxy firewalls mask your IP address and limit traffic types. These firewalls works at the network layer in the OSI model and are more secured than the basic packet filtering firewalls.Īlso called the application level gateways, Proxy Server Firewalls are the most secured type of firewalls that effectively protect the network resources by filtering messages at the application layer. These smart and fast firewalls use an intelligent way to ward off the unauthorized traffic by analyzing the packet headers and inspecting the state of the packets along with providing proxy services. Stateful Packet Inspection (SPI), which is also sometimes called dynamic packet filtering, is a powerful firewall architecture which examines traffic streams from end to end. They can neither tackle the attacks that use application layers vulnerabilities nor can fight against spoofing attacks. It is to be noted that these types of firewalls cannot prevent all types of attacks.
Packet filtering technique is suitable for small networks but gets complex when implemented to larger networks. It lets a packet pass or block its way by comparing it with pre-established criteria like allowed IP addresses, packet type, port number, etc. Packet Filter Firewall controls the network access by analyzing the outgoing and incoming packets. Let us give you a brief introduction about each of these. Packet Filters, Stateful Inspection and Proxy Server Firewalls. There are three basic types of firewalls that are used by companies to protect their data & devices to keep destructive elements out of network, viz. Firewalls shelters the computer network of an organization against unauthorized incoming or outgoing access and renders the best network security. These are the network security systems (hardware/ software-based) that monitors & controls the traffic flow between the Internet and private network on the basis of a set of user-defined rules. When it comes to prevent unauthorized access of third party in a private network, firewalls are used.
