Fortigate Firewall Functions
The firewall acts as a gatekeeper. It monitors attempts to gain access to your operating system and blocks unwanted traffic or unknown sources.
How to do it? A firewall acts as a barrier or filter between your computer and other networks such as the internet. You can think of a firewall as a traffic controller. It helps protect your network and information by managing your network traffic. This includes blocking unsolicited incoming network traffic and validating access by assessing network traffic for anything malicious like hackers and malware.
Your operating system and security software usually come with a preinstalled firewall. We recommend that you make sure the feature is enabled. Also, check your security settings to make sure they are configured to run updates automatically.
To start, the firewall system analyzes network traffic based on rules. The firewall only accepts incoming connections that have been configured to accept. It does this by allowing or blocking certain data packets, units of communication that you send over digital networks based on predefined security rules.
Fortigate Firewall will work like a traffic guard at your computer’s entry point or port. Only trusted sources, or IP addresses, are allowed in. An IP address is important because it identifies a computer or source, just as a postal address identifies where you live.
How Fortinet Fortigate Firewall Works
For more details on how the Fortinet Fortigate Firewall works, maybe you will start to understand from the description of the working order of the Next Generation Firewall which is guaranteed to be very safe and the best.
When your computer has firewall protection, everything coming in and going out is monitored. The firewall monitors all this informational traffic to allow ‘good data’ to enter, but blocks ‘bad data’ from entering your computer.
Firewalls use one or a combination of the following three methods to control traffic flowing into and out of the network:
Packet Filtering
The most basic form of software firewall uses predefined security rules to create filters. If an incoming packet of information (a small piece of data) is flagged by a filter, it is not allowed to enter. Packets that make it through the filter are sent to the requesting system and everything else is discarded.
Proxy Service
A firewall proxy server is an application that acts as an intermediary between systems. Information from the internet is picked up by the firewall and then sent to the requesting system and vice versa. Firewall proxy servers operate at the application layer firewall, where both ends of the connection are forced to initiate sessions through the proxy.
They operate by creating and running processes on the firewall that mirror the service as if it were running on the end host, and thus centralize all information transfers for an activity to the firewall for scanning.
Inspeksi Stateful
The most modern firewall scanning method, which does not rely on memory intensive inspection of all packets of information is “stateful inspection”. The “status” firewall stores the significant attributes of each connection in a trusted information database, for the duration of the session.
These attributes, collectively known as connection status, can include details such as the IP address and port involved in the connection and the sequence number of packets being transferred.
The firewall compares the information transferred to the relevant copy with the transfer stored in the database. If the comparison results in a positive match, the information is allowed, otherwise it is rejected.
