Firewall Techniques

There are several types of firewall techniques:

  1. Packet filter: Looks at each packet entering or leaving the network and accepts or rejects it based on user-defined rules. Packet filtering is fairly effective and transparent to users, but it is difficult to configure. In addition, it is susceptible to IP Spoofing.  
  2. Application gateway: Applies Security mechanisms to specific applications, such as FTP and Telnet servers. This is very effective, but can impose a performance degradation.
  3. Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.
  4. Proxy server: Intercepts all messages entering and leaving the network. The Proxy server  effectively hides the true network addresses.
    In practice , many firewalls use two or more of these techniques in concert.
    A firewall is considered a first line of defence in protecting private information. For greater security, data can be encrypted.

Fire Wall Security

 
A Firewall can either be software-based or hardware-based and is used to help keep a network secure. Its primary objective is to control the incoming and outgoing network traffic by analysing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set.

 A network firewall builds a bridge between an internal network that is assumed to be secure and trusted, and another network, usually an external (inter)network, such as the Internet, that is not assumed to be secure and trusted.

Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet. Many  routers that pass data between networks contain firewall components and, conversely, many firewalls can perform basic routing functions.

 
A Firewall is to protect  our network from the Internet cloud . If you have Broadband or lease line connection you are visible to the world because approximately 50,000 and more ports are open. Hackers any time may come and intrude in our IT setup. We  itech services  are  doing Linux Firewall which has no renewal cost for consecutive years.
We can connect our all branches in one network through our firewall (VPN ).
