This Act takes great strides to strengthen and amend existing computer crime laws, including the U.S. Computer Fraud and Abuse Act and the U.S. Electronic Communications Privacy Act (ECPA), as well as to empower U.S. law enforcement agencies, if only temporarily. U.S. federal courts have subsequently declared some of the Act's provisions unconstitutional. The sections of the Act that are relevant to the CISSP exam include
- Section 202 — Authority to Intercept Wire, Oral, and Electronic Communications Relating to Computer Fraud and Abuse Offenses: Under previous law, investigators couldn't obtain a wiretap order for violations of the Computer Fraud and Abuse Act. This amendment authorizes such action for felony violations of that Act.
- Section 209 — Seizure of Voice-Mail Messages Pursuant to Warrants: Under previous law, investigators could obtain access to e-mail under the ECPA but not voice-mail, which was covered by the more restrictive wiretap statute. This amendment authorizes access to voice-mail with a search warrant rather than a wiretap order.
- Section 210 — Scope of Subpoenas for Records of Electronic Communications: Under previous law, subpoenas of electronic records were restricted to very limited information. This amendment expands the list of records that can be obtained and updates technology-specific terminology.
- Section 211 — Clarification of Scope: This amendment governs privacy protection and disclosure to law enforcement of cable, telephone, and Internet service provider records.
- Section 212 — Emergency Disclosure of Electronic Communications to Protect Life and Limb: Prior to this amendment, no special provisions existed that allowed a communications provider to disclose customer information to law enforcement officials in emergency situations, such as an imminent crime or terrorist attack, without exposing the provider to civil liability suits from the customer.
- Section 214 — Pen Register and Trap and Trace Authority under FISA (Foreign Intelligence Surveillance Act): Clarifies law enforcement authority to trace communications on the Internet and other computer networks, and it authorizes the use of a pen/trap device nationwide, instead of limiting it to the jurisdiction of the court.
A pen/trap device refers to a pen register that shows outgoing numbers called from a phone and a trap and trace device that shows incoming numbers that called a phone. Pen registers and trap and trace devices are collectively referred to as pen/trap devices because most technologies allow the same device to perform both types of traces (incoming and outgoing numbers).
- Section 217 — Interception of Computer Trespasser Communications: Under previous law, it was permissible for organizations to monitor activity on their own networks but not necessarily for law enforcement to assist these organizations in monitoring, even when such help was specifically requested. This amendment allows organizations to authorize persons "acting under color (pretense or appearance) of law" to monitor trespassers on their computer systems.
- Section 220 — Nationwide Service of Search Warrants for Electronic Evidence: Removes jurisdictional issues in obtaining search warrants for e-mail. For an excellent example of this problem, read The Cuckoo's Egg: Tracking a Spy Through the Maze of Computer Espionage, by Clifford Stoll (Doubleday).
- Section 814 — Deterrence and Prevention of Cyberterrorism: Greatly strengthens the U.S. Computer Fraud and Abuse Act, including raising the maximum prison sentence from 10 years to 20 years.
- Section 815 — Additional Defense to Civil Actions Relating to Preserving Records in Response to Government Requests: Clarifies the "statutory authorization" (government authority) defense for violations of the ECPA.
- Section 816 — Development and Support of Cybersecurity Forensic Capabilities: Requires the Attorney General to establish regional computer forensic laboratories, maintain existing laboratories, and provide forensic and training capabilities to Federal, State, and local law enforcement personnel and prosecutors.
The USA PATRIOT Act of 2001 changes many of the provisions in the computer crime laws, particularly the U.S. Computer Fraud and Abuse Act and the Electronic Communications Privacy Act of 1986.
