30c3 – counterstrike “lawful interception”

A judicial or administrative order authorizes a Law Enforcement Agency (LEA) to conduct electronic surveillance on a person (a target). Certain legislation and regulations require service providers (SPs) and Internet service providers (ISPs) to enforce their networks to expressly promote permitted electronic surveillance in order to facilitate the lawful intercept process.
Wiretaps on conventional telephone and Internet systems in voice, data, and multiservice networks are used to conduct surveillance. The LEA sends a wiretap request to the target’s service provider, who is in charge of intercepting data traffic to and from the person. The service provider decides which of its edge routers manages the target’s traffic based on the target’s IP address or session (data communication). The service provider then intercepts the target’s traffic as it passes through the router, and without the target’s knowledge, sends a copy of the intercepted traffic to the LEA.

Lawful interception (LI) was usually conducted on the legacy public switched telephone network (PSTN), wireless, and cable networks by gaining access to the mechanical or digital switches that enabled the targets’ calls. Over the last two decades, the advent of packet switched networks, softswitch technology, and server-based applications has radically changed how LI is conducted.
The act of accessing communications network data under lawful authority for the purposes of study or evidence is known as lawful interception. Signaling or network management information, or, in rarer cases, the content of the communications, are examples of such data. The operation is known as access to retained data (RD)[citation needed] if the data are not accessed in real-time.
Infrastructure safety and cybersecurity are just two of the many reasons for this operation. The operator of public network infrastructure will, in general, participate in LI activities for those purposes. Unless otherwise prohibited, operators of private network infrastructures in the United States have an inherent right to retain LI capabilities within their own networks[citation needed].

The mechanism through which law enforcement agencies perform electronic surveillance of circuit and packet-mode communications as allowed by judicial or administrative order is referred to as “lawful intercept.” Countries all over the world have passed legislation requiring public and private communication service providers (service providers) to expressly develop and enforce their networks to facilitate authorized electronic surveillance. Standards have also been developed by international standards bodies to direct service providers and manufacturers in the production of unique lawful intercept capabilities.
