SkyX offer software defined network based firewall with partnering with Cisco Technology.
Traditional firewall is a system that secures incoming network packets, which come from various sources, as well as outgoing network packets. It can monitor and control the flow of data which comes into the network from different sources, and works on the basis of predefined rules.
It is widely accepted that Firewalls typically maintain a barricade between a confidential, protected internal network and another outside network, such as the Internet, which is assumed not to be secure or trusted. They can be categorised as either hardware or software firewalls. Network firewalls are software programs running on different hardware appliances in the network.
While a Software based firewalls provide a layer of software on a host, which controls network traffic in and out of that particular machine. Firewall appliances may also provide other functionality to the internal network they protect, such as acting as DHCP or VPN servers for that network.
The system analyses data packets for parameters like layer2 or layer3 switch packet formats. It can also perform deep packet scrutiny for higher layer parameters (like application type and services, etc) to filter network traffic.
Firewalls are an essential component of any secure network communication for bi-directional packet flow.
There are many benefits of SDN are:
- Directly programmable
- Centrally managed
- Programmatically configured
- Experimenting and research is not expensive
- Fast upgrades
Implementing a Software defined network based firewall provides a Management Layer which enables security administrators with real-time visualization of security incidents. With this information they can enhance their incident response and overall insight into the network security posture. Because it is open and modular, the Management Layer provides administrators with a great deal of flexibility in definition and delegation of security.
By implementing the firewall defined a protection and monitoring system that adapt rapidly in the face of new threats and changing network configurations. It develops these protections using advanced threat intelligence and then deploys precision policy updates using the enforcement points created by the Enforcement Layer.
