Prohibited Software

Any software identified as "Freeware" or "Shareware" whose EULA specifically states NOT for use on Government/commercial systems should not be loaded on SLAC computer systems.

Any software that contains Personally Identifiable Information (PII) that has not been specifically approved by OCIO must not be installed on any SLAC computer systems. e.g. TurboTax, TAxACT, H&R Block At Home, CompleteTax, QuickenPro, etc.

Unauthorized use of tools that interfere with information resources (e. g. port scanners or vulnerability scanners), tools that crack passwords, encryption keys, license keys, etc., and use of tools to gain unauthorized access may result in disciplinary or legal action. Authorization must come from the CIO and is normally only granted to members of the SLAC computer security team.

Any system found running prohibited software will be required to remove the software immediately. Some systems, depending on the software found running on it, will be required to be completely rebuilt to ensure the system is "clean" (not compromised).

• Software license or password cracking software is strictly prohibited.
• P2P or Filesharing: This software is completely prohibited at SLAC. Some examples of software product names which are P2P or filesharing are eMule, Gnutella, LimeWire, and Kazaa. Many other products are P2P or filesharing but they are not specifically listed here. All are prohibited.
• ZoneAlarm (free version): The EULA specifically states that government and educational institutions cannot use the free version of ZoneAlarm.
• Microsoft Security Essentials is not licensed for installing on any SLAC/DOE computer.
