Hi, I wonder if anyone could help me please I am rather security conscious and go a step further than most people I BLOCK all OUTBOUND firewall connections BY DEFAULT.

What is firewall Definition from What. Is. com. A firewall is a network security system, either hardware or software based, that uses rules to control incoming and outgoing network traffic. A firewall acts as a barrier between a trusted network and and an untrusted network. A firewall controls access to the resources of a network through a positive control model. This means that the only traffic allowed onto the network is defined in the firewall policy all other traffic is denied. By submitting your personal information, you agree that Tech.

History and types of firewalls. Computer security borrowed the term firewall from firefighting and fire prevention, where a firewall is a barrier established to prevent the spread of fire. When organizations began moving from mainframe computers and dumb clients to the client server model, the ability to control access to the server became a priority. Using Firewall To Block Adobe In Host' title='Using Firewall To Block Adobe In Host' />Before firewalls emerged in the late 1. ACLs residing on routers. ACLs determined which IP addresses were granted or denied access to the network. The growth of the Internet and the resulting increased connectivity of networks meant that this type of filtering was no longer enough to keep out malicious traffic as only basic information about network traffic is contained in the packet headers.

The earliest firewalls functioned as packet filters, inspecting the packets that are transferred between computers on the Internet. When a packet passes through a packet filter firewall, its source and destination address, protocol, and destination port number are checked against the firewalls rule set. Any packets that arent specifically allowed onto the network are dropped i. For example, if a firewall is configured with a rule to block Telnet access, then the firewall will drop packets destined for TCP port number 2. Telnet server application would be listening. Packet filter firewalls work mainly on the first three layers of the OSI reference model physical, data link and network, although the transport layer is used to obtain the source and destination port numbers. While generally fast and efficient, they have no ability to tell whether a packet is part of an existing stream of traffic. Because they treat each packet in isolation, this makes them vulnerable to spoofing attacks and also limits their ability to make more complex decisions based on what stage communications between hosts are at. Stateful firewalls. In order to recognize a packets connection state, a firewall needs to record all connections passing through it to ensure it has enough information to assess whether a packet is the start of a new connection, a part of an existing connection, or not part of any connection. This is whats called stateful packet inspection. Stateful inspection was first introduced in 1. Check Point Software in its Fire. Wall 1 software firewall, and by the late 1. This additional information can be used to grant or reject access based on the packets history in the state table, and to speed up packet processing that way, packets that are part of an existing connection based on the firewalls state table can be allowed through without further analysis. If a packet does not match an existing connection, its evaluated according to the rule set for new connections. Application layer firewalls. As attacks against Web servers became more common, so too did the need for a firewall that could protect servers and the applications running on them, not merely the network resources behind them. Application layer firewall technology first emerged in 1. OSI layer up to the application layer. The key benefit of application layer filtering is the ability to block specific content, such as known malware or certain websites, and recognize when certain applications and protocols such as HTTP, FTP and DNS are being misused. Firewall technology is now incorporated into a variety of devices many routers that pass data between networks contain firewall components and most home computer operating systems include software based firewalls. Many hardware based firewalls also provide additional functionality like basic routing to the internal network they protect. Proxy firewalls. Firewall proxy servers also operate at the firewalls application layer, acting as an intermediary for requests from one network to another for a specific network application. A proxy firewall prevents direct connections between either sides of the firewall both sides are forced to conduct the session through the proxy, which can block or allow traffic based on its rule set. A proxy service must be run for each type of Internet application the firewall will support, such as an HTTP proxy for Web services. Firewalls in the perimeterless age. The role of a firewall is to prevent malicious traffic reaching the resources that it is protecting. Some security experts feel this is an outdated approach to keeping information and the resources it resides on safe. They argue that while firewalls still have a role to play, modern networks have so many entry points and different types of users that stronger access control and security at the host is a better technological approach to network security. Virtualization strategies such as virtual desktop infrastructure can dynamically respond to different scenarios by offering tailored access control to applications, files, Web content and email attachments based on the users role, location, device and connection.

This approach to security does provide additional protection that a firewall cant, but information security requires defense in depth, and firewalls still offer essential low level protection as well as important logging and auditing functions.
