Types of Network Boundaries
There are several types of network boundaries that can be used to secure an organization’s network. These include:
- Firewall: A firewall is a type of network boundary that is used to protect a network from external threats. It works by monitoring incoming and outgoing traffic and blocking malicious traffic from entering the network.
- Access Control Lists (ACLs): ACLs are used to control access to the network. They are used to specify which devices and services can access the network and which are not allowed.
- Network Address Translation (NAT): NAT is used to hide the IP addresses of devices on the network. This helps protect the network from malicious attacks and unauthorized access.
- Virtual Private Networks (VPNs): VPNs are used to create secure tunnels between two networks. This allows users to access the network remotely while their traffic is encrypted.
- Intrusion Prevention Systems (IPS): IPS is used to detect and block malicious traffic from entering the network. They work by analyzing incoming traffic and blocking any suspicious activity.
What are Network Boundaries?
Network boundaries are the limits that define where a network begins and ends. They are used to specify the range of devices and services that are allowed on the network. Network boundaries are also used to protect the network from unauthorized access and malicious attacks. Network boundaries are important for organizations because they help to secure their networks from external threats. They also help to ensure that only authorized users are allowed access to the network. Without network boundaries, malicious attackers could gain access to sensitive data or disrupt network operations. Network boundaries can be physical or virtual. Physical boundaries are typically used to separate different networks or subnets. For example, a company may have a separate internal network for employees and a separate external network for customers. Virtual boundaries are used to define the range of IP addresses and services that can be accessed from the network. For example, a company may only allow certain IP addresses to access certain services on its network. This ensures that only authorized users are able to access the network and use its services.
