What Is VLAN Hopping Attacks? VLAN hopping is a type of network attack that exploits certain properties of the VLAN (Virtual Local Area Network) setup, particularly on switches, to gain unauthorized access to traffic of other VLANs that would normally be restricted. VLANs are used to segment network traffic, with the purpose of increasing security and performance by… Read More »
What is PPP? A point-to-point connection is the most common type of WAN connection. PPP connections are used to connect LANs to service provider WANs and to connect LAN segments within an organization network. A LAN-to-WAN point-to-point connection is also referred to as a serial connection or leased-line connection because the lines are leased from a carrier (usually a telephone company)… Read More »
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 Multi-Area OSPFv3? Before we look at Multi-area OSPF, you must understand OSPF single-area concepts and configuration. OSPF (Open Shortest Path First) is a classless (supports VLSM and CIDR.), Link State Routing Protocol with an Administrative distance (AD) of 110. OSPF is more efficient than distant vector routing protocols, any routing changes trigger OSPF routing updates which are propagated… Read More »
What Is Native VLANs? A Native VLAN is a term used in networking, mainly in the context of VLAN tagging which is a part of the IEEE 802.1Q standard. In a VLAN setup, multiple virtual networks are configured on a single physical network infrastructure to segment traffic for efficiency and security purposes. The Native VLAN plays a special… Read More »
