      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

      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

    • Firewalls

      Firewalls

      A firewall is a software component that restricts unauthorized inward network access. It allows outward information flow. It is set up to control traffic flow between two networks by configured permissions like Allow, Deny, Block, Encrypt, etc. It is normally employed to avoid illegal access to personal computers or corporate networks from external unsafe entities

      Honey Monkey

      Honey monkeys are a new way of detecting malicious codes from websites that try to exploit certain vulnerabilities of Internet browsers. The honey monkey system works as an automated web/internet patrol system that is designed to detect harmful materials in the Internet, to be able to come up with solutions, and to catch the people

      Denial of Service (DoS) Attacks

      A Denial of Service (DoS) attack is one that attempts to prevent the victim from being able to use all or part of his/her network connection. A denial of service attack may target a user to prevent him/her from making outgoing connections on the network. It may also target an entire organization to either prevent

      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

    • 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

    • 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

    • TCP Sequence Prediction Attack

      TCP Sequence Prediction Attack

      A TCP sequence prediction attack is an attempt to hijack an existing TCP session by injecting packets which pretend to come from one computer involved in the TCP session. The TCP Sequence Prediction Attack TCP is a reliable connection-oriented layer 4 (Transport Layer) protocol. Packet transfer between hosts is accomplished by the layers below layer
