First of all, what is a network?
The network we refer to here is a computer that has so many definitions of many sources, whether online or elsewhere. Simply put, a network between the connection cables and other communications media, connectivity equipment, such as switches and routers, electronic devices such as computers, printers, scanners, plotters, etc., in order to share data and resources.
Whoa! Now, that does not sound simple at all, is it? Alright, let’s give it a second try …
A Network is the connection protocol, connection equipment and electronic devices in order to share data and resources.
Now, it was not too hard, was it? And here’s the second question …
What is Security?
This is easy, as the word means the safety or preservation, protection or welfare.
So simply put, Network Security refers to any company which is intended to protect the network.
Why do we protect or “Secure” network?
We need to protect the network because it is a constant threat against the “resources” that we share in the net. This could be valuable information or data about our employees and customers, or more importantly about our products or company. Most of these threats come in the form of
* viruses, worms and Trojan horses
* Spyware and adware
* zero-day attacks, also called zero-hour attacks
* Hacker attacks
* denial of service attack
* Data interception and theft
* Identity Theft
In order for us to fully understand what the “Network Security Solution” is all about, we must also understand how network security works. Because there are a variety of threats, there is no single solution. We need multiple layers of security, so that if one fails, the attacker would have to deal with the next song.
Network Security Systems are usually composed of many elements of both software and hardware that are designed to work together to improve security and integrity. . The software will relentlessly updated to prevent new threats from
These factors are:
* Anti-virus and anti-spyware
* Firewall to block unauthorized access to your network
* Intrusion prevention system (IPS) to detect and block attacks
* Virtual Private Networks (VPNs), to provide secure remote access
