Unsecured Access Routes
The recent rise in reported cases of phishing and TDoS (telephony denial of service) attacks prompted the US Department of Homeland Security to highlight the tactics and the digital intelligence with which cyber criminals have armed themselves for the purposes of extorting revenue and/or deliberately disrupting critical infrastructure for sustained periods Advertised Freephone, Lo-Call and DDI number ranges are unsecured access routes that facilitate malicious callers to directly access and disrupt UC services or extort data and/or revenue from staff members. critical infrastructure from other cyber threats such as TDoS (telephony denial of service), phishing and eavesdropping
The simplicity of these crimes stems from the distinct lack of telephony network security. Unlike data networks that depend on firewall security as a pre-requisite for IDS (intrusion detection system) and IPS (intrusion prevention system), the telephony network offers a platter of unsecured access routes for malicious callers to target their prey.
