A method for preventing an email phishing attack is disclosed. The method involves calculating a victim risk score of a user, receiving an email addressed to the user containing at least one of an attachment and a URL, based on the victim risk score of the user, performing one of: forwarding the email to the user with the at least one of the attachment and the URL, forwarding the email to the user without the at least one of the attachment and the URL, holding the email and the at least one of the attachment and URL in quarantine and blocking the email from being forwarded to the user.

Methods for Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) design for IP Multimedia Subsystems (IMS) include determining that a network is a flat MPLS-enabled Voice over Internet Protocol (VoIP) or Unified Communications IMS network including an IMS Core site and excluding Session Border Controllers (SBCs). The network further includes multiple user endpoints (UEs). Responsive to determining that the network is a flat MPLS-enabled VoIP or Unified Communications IMS network, the computer system configures a first set of TE LSPs between each UE and the IMS Core site. The computer system configures a second set of TE LSPs between each UE and each other UE of the plurality of UEs to form a full mesh. A display device of the computer system generates a graphical representation of the network. The graphical representation represents the first set of TE LSPs and the second set of TE LSPs connecting each UE.

Methods for Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) design for IP Multimedia Subsystems (IMS) include determining that a network is a hierarchical MPLS-enabled network including a single IMS Core site and multiple Session Border Controllers (SBCs). Responsive to determining that the network is a hierarchical MPLS-enabled network, the computer system configures a first set of TE Label Switching Paths (LSPs) between each SBC of the multiple SBCs and the single IMS Core site. The computer system configures a second set of TE LSPs between each SBC of the multiple SBCs and each other SBC of the multiple SBCs to form a full mesh. The network further includes multiple user endpoints (UEs). The computer system configures a third set of TE LSPs between each UE of the multiple UEs and an SBC of the multiple SBCs. The UE is configured to use the SBC.

A method for preventing Medium Access Control (MAC) spoofing attacks in a communication network may include obtaining, by a protection layer, a connecting request for connecting a terminal to the communication network. The method may include issuing, by the protection layer, a MAC authentication request to a Network Access Control (NAC) server, the MAC authentication request may be a request to determine whether a MAC address of the terminal is whitelisted. The method may include responding, by the NAC server, to the MAC authentication request of the protection layer by allowing the terminal to join the communication network based on whether the MAC address of the terminal is whitelisted. The method may include sending, by the NAC server, a log message to a log analyzer server, the log message including a result identifying whether the MAC address of the terminal is whitelisted.

Method and system for preventing medium access control (MAC) spoofing attacks in a communication network

Systems and methods include a method for securing an Internet protocol (IP) Multimedia Subsystem (IMS)-based voice over IP (VoIP) network with multiple virtual private networks (VPNs). A call sent by a first user endpoint (UE) to a second UE is received by a SBC. The SBC provides security for an IMS-based VoIP network and controls traffic between a first VPN connecting IMS core servers, a second VPN connecting IP phones, and a third VPN connecting non-IP-phone devices. The call originates from either of the second VPN connecting the IP phones or from the third VPN connecting the non-IP-phone devices. A signaling for the call is encrypted and routed by the SBC to the second UE. A media flow for the call is encrypted and routed by the SBC through the third VPN before routing the call to the second UE.
