      Cisco VPN Error 412

      The CISCO VPN Client is a popular software application that allows end-users to connect a computer to a VPN (virtual private network). Once connected, the client computer can leverage the resources of the remote network in a secure environment as if connected directly to the local network. Unfortunately, a common error that can arise for

    • IP Address Spoofing

      IP Address Spoofing

      IP address spoofing denotes the action of generating IP packets with fake source IP addresses in order to impersonate other systems or to protect the identity of the sender. Spoofing can also refer to forging or using fake headers on emails or netnews to – again – protect the identity of the sender and to

      How to Disable the Netgear Router Firewall

      In most cases, disabling the firewall on a Netgear router is a really bad idea. In fact, it is such a bad idea that Netgear does not even make a button in their GUI that does this. Nevertheless, users can effectively disable a Netgear router firewall just by adding a rule or two to the

    • ISAKMP

      ISAKMP

      ISAKMP (Internet Security Association and Key Management Protocol) is a protocol for establishing Security Associations (SA) and cryptographic keys in a internet environment. ISAKMP defines the procedures for authenticating a communicating peer, creation and management of Security Associations, key generation techniques, and threat mitigation (e.g. denial of service and replay attacks). ISAKMP typically utilizes IKE

    • Two Factor Authentication

      Two Factor Authentication

      Two factor authentication is term used to describe any authentication mechanism where more than one thing is required to authentate a user. The two components of two factor authentication are: Something you know Something you have Traditional authentication schemes used username and password pairs to authenticate users. This provides minimal security, because many user passwords

      Access Control

      Access control is the execution of limitations and restrictions on whoever tries to occupy a certain protected property, thereby keeping people as safe as possible. As modern society moves further into the cyber age, these access control systems become almost completely computer controlled. This article will further explain what access control is, how it works,

      Intrusion Detection System (IDS)

      Consumers commonly mistake an intrusion detection system (IDS)with a computer firewall. Although both applications have a similar goal to protect end-users from nefarious hackers and computer malware, an IDS differs from a firewall in that it can be either a device or software program created to monitor an individual computer, computing device, or network for

      RADIUS (Remote Authentication Dial In User Service) is a system procedure that offers centralized entrance, approval, as well as accounting administration for individuals or computers to add and utilize a network service. Individuals often need “Authentication” when they try to fix to a network. People have to face far more problems while connecting their computers

    • IKE (Internet Key Exchange)

      IKE (Internet Key Exchange)

      The term Internet Key Exchange refers to the networking protocol that designed to configure a SA (security association) within the IPsec protocol suite of applications. Internet Key Exchange (or IKE) is constructed on top of ISAKMP and the Oakley protocol and is often used in the VPN tunneling process. X.509 certificates are used for authentication

    • Packet Fragmentation

      Packet Fragmentation

      Every packet based network has an MTU (Maximum Transmission Unit) size. The MTU is the size of the largest packet that that network can transmit. Packets larger than the allowable MTU must be divided into smaller packets or fragments to enable them to traverse the network. Network Standard MTU Ethernet 1500 Token Ring 4096 Packet
