The Type "N" connector, commonly known as the N connector, is used to join coaxial cables using a threaded RF connector. It was one of the first connectors to be capable of carrying microwave-frequency signals. Invented by Paul Neill of Bell Labs in the 1940s, the connector is named after him. Design Details These connectors were devised to carry signals that could reach 1 GHz in certain military applications. The Type N connector that is commonly used today can easily handle up to 11 GHz. However, that was just the Read More

A honeypot is a trap that's used to identify, avert and, to some extent, neutralize attempts to hijack information systems and networks. It is usually made up of a single computer or a network site that disguises itself as a normal computer or network. It can also morph to look like an unused IP address, a file or a record. It tempts hackers by pretending to contain data that cyber criminals often deem important. It can deceive the hacker into thinking that it is an open proxy. A honeypot is Read More

VLAN Hopping is one of the primary VLAN based attacks used by hackers to infiltrate network security. VLAN hopping is used to attack a network by sending packets to a port which is generally not accessible. VLAN hopping attacks are mainly conducted in the Dynamic Trunking Protocol and, in some cases; the attacks are targeted to the trunking encapsulation protocol (802.1q or ISL). The Dynamic Trunking Protocol is utilized for negotiating trunking on links between devices and the type of trunking encapsulation to be used. Types of VLAN Hopping Switch Read More

Understanding the Cisco Three-Layer Hierarchical Model Hierachical network design helps us to make networks more reliable and predictable. Level by level design help to understand networking factions easily like, we can use tools like access lists at specific level and can avoid them from others. Cisco layer model consist of the following three layers. The Core layer The Distribution layer The Access layer Each layer plays a role and specific responsibilities are assigned to these three logical layers. These layers are same like the network layers of OSI reference model. Read More

EAP, LEAP, PEAP, and TTLS are competing protocols for securely transporting authentication data. EAP EAP (Extensible Authentication Protocol), defined in RFC 2284 — PPP Extensible Authentication Protocol (EAP), is the original 802.11 standard. LEAP LEAP (Lightweight Extensible Authentication Protocol) is a proprietary protocol which was developed by Cisco. Cisco is phasing out LEAP in favor of PEAP. EAP-TLS EAP-TLS (Extensible Authentication Protocol – Transport Layer Security) was created by Microsoft and accepted by the IETF as RFC 2716: PPP EAP TLS Authentication Protocol.. PEAP PEAP (Protected Extensible Authentication Protocol) is Read More
