Understanding the Importance of a Firewall

Connectivity is vital to the success of businesses everywhere in the worldwide marketplace. Whether a small business or a conglomerate, companies need to be protective of their systems and their data. In a day and age where cyber threats are a real concern, putting protective components in place to safeguard information is vital. Firewalls in cyber security are security devices which help to protect computer networks from unauthorized access to data. They create a barrier between secured computer networks and the untrusted networks associated with the internet. Firewalls have been the first line of defence for more than twenty-five years.

Types of Firewalls

There are two types of firewalls. Those are listed below:

  • Software Firewalls
  • Hardware Firewalls

Software firewalls are programs that can be installed on various user devices. They can monitor and regulate network traffic through various port numbers and applications.

Hardware firewalls are pieces of equipment which allow your computer network and data systems to connect to a gateway which provides the link to the internet.

Why Are Firewalls Important?

Firewalls can block application-layer attacks and attacks from malware. They can detect and combat unwanted activity throughout the network. They provide enhanced security and ensure that unauthorized users cannot access private networks and data. It counteracts phishing attacks as well. Business-grade firewalls stop outflowing data when it recognizes a social engineering attack.

Firewalls also identify dangerous users and applications and can send alerts when a threat is detected. Firewalls are an integral part of any network security infrastructure.
