A firewall is a system that is designed to prevent Unauthorized access from entering a private internal and external network. A firewall creates a secured barrier between a private network and the public internet network. This protects your network from 'hackers' logging into the machine. A firewall blocks traffic from the outside to the inside. A firewall is most especially important to large organizations. A firewall can be implemented in both hardware-based and software-based or a combination of both. What does the firewall do? Firewall protects your personal information from hackers. A firewall limits you expose _ blocks "pop up" ads and certain cookies. Firewalls are manage and control inside and outside network traffic. Firewall blocks malicious data, massage, application, port number, protocol, packet based on content, source address. A firewall is capable of hiding the structure and addressing the scheme of a private network from the public.

Types of firewall:
Packet-filtering firewall A packet filter firewall is the simplest firewall. It is used to control network access by incoming and outgoing packers. The firewall applied its rule set to determine which packets allow or disallow. It examines each on the source of IP address, destination of IP address, TCP/UPD source port, TCP/USD destination port. It's also called static filtering. Circuit level gateway Circuit level gateway work at the session layer of the OSI model. It is set up between TCP/IP connect. It supports much protocol and easy to maintain. It is protected external traffic on the network. An example of this is the SOCKS packet. Stateful inspection firewall Stateful inspection is a firewall technology it can monitor the state of actuating network connections to use this information of determining which network packets to allow through the firewall. Stateful inspection analysis packets down to the application layer. Its also called dynamic packets filtering. Application-level gateway ( proxy firewall) The application-level gateway can give high-level security. The gateway can be configured to support application-level or proxy service inbound connection circuit-level function for outbound connection. It is service-specific. It acts as a really of application-level traffic. The only allowable application can be passed through. Next-generation firewall Next-generation firewall (NGFW) is an advance version of the traditional firewall. It is a part of third-generation technology. It provides proper Security. It blocks malware from entering the network. Next-generation firewall improving filtering network traffic on packets contents. Software firewall A software firewall protects a single computer. It protects internal systems. Usually, the software firewall is less expensive and it's easier to configure. The software firewall intercepts each connection request and determines whether the request allows or not allow. Hardware firewall A hardware firewall protects the whole network. It is an implemented router label. It can provide high speed and higher security. Hardware firewall easily integrated with other security features like DLP, IPS/IDS Sandboxing, deep packet inspection. It is usually expensive. Cloud-based firewall The cloud-based firewall protects the network from cyber attacks direct at these cloud assets. The Cloud firewall has two flavors-vanilla and strawberry. Both are software. It blocks malicious traffic. Read the full article
