What Are Layer 2 Network Attacks? Layer 2 network attacks target the Data Link layer (Layer 2) of the OSI (Open Systems Interconnection) model. This layer is responsible for node-to-node data transfer and controls the flow of data between two directly connected nodes. It also handles error checking and frames synchronization. Common Layer 2 network components include switches,… Read More »
What is Network Address Translation (NAT)? Network Address Translation (NAT) is a method used in networking to modify network address information in the header of IP packets while they are in transit across a traffic routing device. The primary purpose of NAT is to enable multiple devices on a local network to access the internet using a single public… Read More »
What Is Netflow? NetFlow is a network protocol developed by Cisco Systems for collecting IP traffic information and monitoring network flow. It’s widely used for network traffic analysis and forms the basis for a variety of network management and security applications. Here’s a brief overview of how NetFlow works: Data Collection: NetFlow-enabled devices, like routers and switches, keep… Read More »
What Is iBGP? Interior Border Gateway Protocol (iBGP) is a part of the Border Gateway Protocol (BGP) family, which is used for exchanging routing information within a single Autonomous System (AS). An AS is essentially a large network or group of networks under a common administration, often belonging to an organization or an internet service provider. Here are… Read More »
What Is InterVLAN? We define inter-VLAN routing as a process of forwarding network traffic from one VLAN to another VLAN using a router or layer 3 device. A VLAN is a sub-group within a network, which partitions and isolates network traffic at the data link layer (Layer 2) of the OSI model. VLANs are used to segment networks for… Read More »
