Actually, an IDS does not sit on one particular layer. It has to examine packets for protocols, how they are being transported, number of packets transmitted, spoofing information, and application layer information.
In general terms, Intrusion detection system and Intrusion prevention system is a Layer 4 device. It filters for malicious data.

How do you set SCSI device IDs if your host adapter is not scam compliant?
Using jumpers or rotary dials (or another type of switch) on the device itself
Can a switch be used to connect two lans with different network ids?
Yes, a switch can be used to connect two LANs with different network IDs, but it requires some additional configuration. Typically, switches operate at Layer 2 (Data Link Layer) and do not route traffic between different network IDs. To enable communication between the two LANs, a router or a Layer 3 switch would be needed to handle the routing of packets between the different subnets.
What is the advantage of configuring IDS filter rules if you have already packet filtering rules in place?
you gain another layer of security.
What type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
What are the main things in a water filtration device?
layer of sand then a layer of activated charcoal then a layer of gravel.
Which are layer 1 switches?

Why is a switch called as layer 2 device?
because one layer is the electrical part, and the other layer is the place where the switch is on.
What device is also called a Layer 3 switch?
i do no
What kind of device is a hub considered to be?
