Firewall technologies

Wi-Fi is a wireless network technology that permits gadgets, cell phones and other hardware to interface with the Internet. Most households and organizations put forth an admirable attempt to keep unauthorized clients off their networks, however Wi-Fi passages and routers can give hackers a helpful route in.

Firewall – It is designed to prevent any external or unauthorized users from bugging in even from their private network. These firewalls protect any unrecognized users from accessing organizations private network like intranets. The few types of firewalls include Packet Filters, Stateful inspection, Next generation, Circuit-level and Application level gateway.

There are several ways in which we can protect wireless networks –

•Use a secure WPA password – Each and every router comes with encryption. This encryption is helpful in scrambling the data which makes it unreadable. The password used here should be random and long so that it is almost impossible for the hacker to crack it.

•Changing the Router’s SSID – Service set identifier (SSID) is used as a default by many vendors who ship their wireless networks using the same. If we still use the default SSID then it signals the hackers that your wireless network is not properly configured and thus is prone to attack.

•Providing separate network for guests

•Using a firewall

•Change the credentials of router’s admin

•To ensure Wifi connection is strong

•Remote Management should be turned off

Many hardware firewalls are using packet filtering, to find out the destination and source we need to look at the packet header. This provides details whether to use the packet means it is legitimate or not, if so we can discard it.Software firewall provides better network traffic or idea to pass through the device and they usually run on the end point of the device.

Following are the few ways that can expose firewall security-

1. The more we modernized the firewall, the more difficult it become to operate and manage.

2.  Oversize integration and poor management can also lead to blind spot the admins to handle the chaos.

3. Due to great evolution in firewall industry, as they can look for the originating application or user device. It requires deep technology to look for the thread which again lead to breakage of complete security system.
