Which of the following is given to a notification from a firewall that a specific event or packet was detected?
a. management interface
b. rules
c. alert
d. anomaly-based detection
A firewall is a piece of network security equipment that keeps an eye on both incoming and outgoing network traffic and allows or denies data packets in accordance with a set of security rules. Its goal is to create a physical barrier between your internal network and incoming traffic from outside sources (like the internet), blocking unwanted traffic like that of hackers and viruses.
In order to stop attacks, firewalls thoroughly examine incoming communication in accordance with pre-established criteria and filter traffic from untrusted or dubious sources. Firewalls monitor traffic at a computer's ports, which are the entry points via which data is shared with external devices. Such a statement might read, "Source address 172.18.1.1 is allowed to reach destination 172.18.2.1 through port 22."
Consider port numbers as the rooms in the home and IP addresses as the houses. It is further filtered such that persons inside the house are only permitted to access specific rooms (destination ports), depending on whether they are the owner, a child, or a visitor. Only trusted people (source addresses) are allowed to enter the house (destination address) at all. While kids and visitors are not permitted in any room (or port), the owners are permitted to enter a specific set of rooms (specific ports).
