in this era of digitalization, cyberattacks can be extremely devastating for companies. It is predicted that the cost of cybercrime was around $600 billion. The cyber attacks are continuing to increase so that is why experts are under high pressure to protect customer networks from threats. Being a managed service provider, you must know that having a firewall can create a huge difference in network security. Firewalls allow protecting networked and devices from a broader range of security risks. They can inform you regarding the potential threatening attempts to link from the customer network.

Firewalls are the software that works as the filtration system for the data supposed to enter into the device or computer. The main task of firewalls is to scan packets for malicious code or attacks that have been recognized as potential threats. It prevents it from entering into your devices if there is a risk identified from the data. There are various ways security firewalls can regulate network traffic. Some of this process is mentioned below:

Packet Filtering

Packets are the little amounts of data that attempt to enter the network that is run against a group of filters. These filters are known for eliminating the packets that match specific identified threats and facilitate the other via to their intended destination.

Proxy Service

In cybersecurity companies, these are considered extremely protected but there are some negative aspects of them. Proxy service is much slower than other types of firewalls and is normally limited about the sorts of applications they can support. Rather than serving like a filtration system that data goes through, they do function as a go-between. By making a mirror of the computer behind the firewall, they avoid having direct connections between the incoming pockets and the customer device, securing your network location from potential bad actors.

Tasteful Inspection

Tasteful inspection is different from static filtering as it examines the several elements of each data packet and compares these elements with the trusted information database. These elements can include destination IP addresses, sources, applications, and ports. The incoming data must match the trusted information to be the firewall. This is considered the newer method of firewall filtering.
