Security against every IT threat
New threats need new answers. But how can you avoid threats you have no idea about that comes from people you do not know.
The answer is FIREWALL.
A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.Firewalls have been a first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet. A firewall can be hardware, software, or both.
Firewall makes the access decisions and decides whether to provide access to the users or not. The firewall does research over the user like its IP, keywords and other access parameters. When the firewall allows it, the traffic gets access to the data and network. So firewall protects the network and data from the wrong kind of access or softwares.
So What does a firewall really do?
A firewall is a program or device that acts as a barrier to keep destructive elements out of a network or specific computer. Firewalls are configured (in hardware, software, or both) with specific criteria to block or prevent unauthorized access to a network. They work as filters for your network traffic by blocking incoming packets of information that are seen as unsafe. In large corporations, if a firewall is not in place, thousands of computers could be vulnerable to malicious attacks. Firewalls should be placed at every connection to the internet and are also used to control outgoing web traffic as well in large organizations.
Firewalls use several strategies to control traffic flowing in and out of networks. Packet filtering is when small chunks of data (called packets) are run through a filter and analyzed. Stateful inspection is where the contents of each packet are not examined, but instead key parts of the packet are compared to a database of trusted information, letting through the packets that pass this test. Firewalls can be configured to filter by several variables: IP address, domain name, protocol, port or even specific words or phrases. Though some operating systems come with a built-in firewall, internet routers also provide very affordable firewall protection when configured properly.
Not many people will make a network without putting a firewall protection on it.so what actually is a firewall. Firewalls are one of the oldest piece of networking security gear that we have. In the initial days,when networking and web traffic was not what it today is, firewall was not so good. But new generation firewall is designed for new businesses that wants to keep the bad guys and hackers away from their network. As the technology has evolved, so has the firewall.
Firewall protects you from the internet or people you don’t want to allow to access some informations. Like if you have 50 computers in your office, firewalls can also provide these computers each with its own IP address. It takes care of everything.For a small house or one person computer, the router is installed with a firewall that connects you to the WAN but for large organizations enterprise level solutions is needed. Thats where cisco firewall series comes in.
