Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What was a limitation of first-generation firewalls?
A
Produced many false positives, thereby overwhelming IT security
B
Filtered only at layer 3 of the OSI model
C
Granular policy capability made managing the firewall too complex
D
Could not distinguish between malicious and legitimate applications
Explanation: 

Detailed explanation-1: -First generation firewalls were relatively simple filter systems called packet filter firewalls, but they made today’s highly complex security technology for computer networks possible. Packet filter firewalls, also referred to as stateless firewalls, filtered out and dropped traffic based on filtering rules.

Detailed explanation-2: -In plain terms, NGFWs have more layers of security built into them, to protect against more sophisticated threats. Crucially, they go beyond the static inspection that traditional firewalls are limited to, instead having application-level control.

Detailed explanation-3: -Next-Generation Firewall: This type of firewall uses deep packet inspection to analyze the data inside each packet. It can identify specific applications and protocols and can block or allow traffic based on the application or protocol.
