Internet is a resourceful destination for many and it is also where ways are built to cause insecurity to the computers and networks. At the same time, online presence cannot be ruled out. In spite of the threats we combat, we still want to make the most of the internet. Through the internet, unauthentic sources can gain access to your computers and networks. In order to protect the computers and the network from unauthorized access, Network security and firewalls is essential.
What are firewalls?
A firewall is a blockage between the internal network and external network. The firewalls detect the authorized sources and make allowance for their access to the network. At the same time, firewalls recognize the unauthorized elements and deny their access to the network. Altogether computer and network security with the firewalls can be achieved.
A firewall is available as both software or hardware or a combined one; the combined firewall offers a more protective solution than the single firewall with more layers of protection.
Firewall performs the following duties:
- Ensures the internal networks are well-secured by filtering the data packets flowing toward the network
- Prevents external sources from attempting to interrupt the networks, which cause a service attack
- Blocks permission for the external source from accessing the networks
Firewalls take care of the overall network security by examining, identifying the authenticity of the external source and allowing or denying permission for the unauthorized sources moving in or out, crossing the firewall. The computers and network security is ensured and any cyber insecurity is put at bay.
