Every move you make, every step you take, it’s the internet that is possibly enabling it, powering the router tucked away in a corner  that are the pivots to keep the work and home worlds revolving.

India’s internet consumption rose by 13% since last few days, according to telecom ministry data that showed Indians consumed 308 petabytes (PB) or 308,000 terabytes (TB) of data daily on an average for the week.

The change reflected how people consumed more streaming content and logged on to work from home, which was also captured in how data demand from residences rose as compared to commercial areas. The data in one PB is equivalent to 500 billion pages of standard printed text.

 

 

 

The past few months have been eye-opening for many of us. While we knew the internet is an integral part of entertainment and even work for most of us, the current situation showed us how it’s pretty much enabling our lives right now. It is keeping us all connected.

 

 

Apart from any physical transmission medium there may be, networks comprise additional basic system building blocks, such as network interface controller (NICs), repeaters, hubs, bridges, switches, routers, modems, and firewalls.

 

 

 

In this scenario securing our network connections plays pivot role and there the importance of firewall emerge.

 

A firewall is a network security device either hardware or software that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.

 

 

  • Accept: allow the traffic
  • Reject: block the traffic but reply with an “unreachable error”
  • Drop: block the traffic with no reply

Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network. A firewall monitors all of the traffic entering your computer network. …

 

 

  • Blocks Trojans. A firewall helps block Trojan horses. …
  • Stops Hackers. Having a firewall keeps hackers out of your network. …
  • Stops Key loggers. Having firewall security will reduce the risk of key loggers monitoring your internet.

Connectivity to the Internet is no longer optional for organizations. However, accessing the Internet provides benefits to the organization; it also enables the outside world to interact with the internal network of the organization. This creates a threat to the organization. In order to secure the internal network from unauthorized traffic, we need a Firewall.
