VLAN (Subclass of VPN)
Networks have grown astronomically over the years , and having an extremely big and unsecured network means that many people are able to gain access to any unsecured network and traffic. What companies usually do is that they hide their local networks behind a firewall among other security mechanisms to ensure that they are secure but it is better for companies to let their employees access the company’s resources from outside the local network. VPN stands for Virtual Private Network and is a method of simulating a private network that is operating on top of a larger network like the internet.
One VPN sub category is VLAN (Virtual Local Area Network) , which is what I am looking into. VPN construct ranges from Layer …show more content…
For the security area, VPN also employs security mechanisms so that the data is not compromised once it goes out and travels through the internet. Users need to authenticate their identity to gain access. Other networks also require that the device the user is on has been labeled as a trusted device before allowing access. Those who are not on a trusted device are not given access even if they have the right username and password. Hence it is very safe and secure.
Intrusion Prevention System
An Intrusion Prevention System is a network security/threat prevention technology that detects and prevent vulnerability exploits. Vulnerability exploits usually come in the form of malicious inputs to an application or service that attackers use to interrupt and gain control of an application. After that, the attacker can disable the target application or access the rights and permissions available to the compromised application. The IPS sits directly behind the firewall and provides a complementary layer of analysis that negatively selects for dangerous content. IPS is placed inline, actively analyzing and taking automated actions on all traffic flows that enter the
