The 1990s was a busy decade for networking. It was during one fateful night in this era-post the development of the network firewall-that Jody Brazil, co-founder and Chief Product Strategist of FireMon, received a call from a customer.
The issue was quite odd–a firewall was blocking traffic between two parts of the network that should have been permitted. “The issue was urgent and critical,” recalls Brazil. “The customer presumed that the firewall was down”
On the contrary, the firewall was functioning perfectly–controlling the network traffic flow as designed. An incorrect change in the firewall made by the customer’s administrator was the culprit.
“The firewall was a complex technology, and it was easy to make a mistake, particularly by IT administrator’s doubling as the organization’s IT security staff,” says Brazil.
