Security Organizations

by Robin Burk

A wide range of organizations exists to help systems administrators and other computer professionals address computer and security needs. This chapter lists a number of the most useful and accessible groups.

The latter part of the chapter also lists online and printed resources that will be helpful to you in planning and executing your security procedures.

Every attempt has been made to ensure that the contact information supplied in this chapter is current as of the date of authoring; however, things may have changed by the time you read this information. You can use your favorite search engine to find these and related Web sites and online information sources to help you with specific problems or put you in touch with supporting organizations.

Government

Several United States government agencies are tasked with gathering and protecting sensitive information. The Defense and Energy Departments, in particular, have provided both the need and the funding for much of the computer security research and development that has occurred over the decades during which use of computers and networks has spread widely. More subtly, these agencies (and especially DOD) were the first to establish formal security procedures, many of which served as prototypes for what is now the best industrial practice in safeguarding computers and computer-based resources.

Several of these U.S. agencies are now tasked with providing advice, information, and consulting to corporate and non-profit organizations. The following is a list of leading agencies.

CIAC-Computer Incident Advisory Capability

CIAC is a product of the movement toward technology transfer from the government's advanced laboratories into commercial use. An activity of the Department of Energy, CIAC is an element of the Lawrence Livermore National Laboratory's Computer Security Technology Center. For decades, Lawrence Livermore Labs was a main site for nuclear weapons development, supercomputing, and security-related concerns.

Although originally formed to support the DOE and its contractors, CIAC now provides a wide range of information to industry and researchers. CIAC is a founding member of the Forum of Incident Response and Security Teams, a global organization described later in this chapter.

E-mail: ciac@llnl.gov

Phone: 510-422-8193

Fax: 510-423-8002

Other resources offered: several e-mail discussion lists, advisories, articles, workshops, and consulting

FIRST-Forum of Incident Response and Security Teams

Over the last decade, companies and governments around the world have experienced both an explosion in the use of networked computers and a corresponding rise in computer security-related incidents. FIRST was formed in 1989 as a global coalition of government, private, and academic organizations to respond to the threat posed by malicious penetration of critical computer systems.

FIRST's Web site states that its mission goes beyond gathering and providing security information. FIRST also provides its members with tools and techniques to improve system security, and works to encourage cooperation and collaboration in addressing potential threats.

URL: http://www.first.org/

Other resources offered: FIRST does not disseminate its information and tools directly to the public, working instead through its member organizations, which include many leading network and computer companies. However, the FIRST web site does provide instructions for contacting the appropriate teams to report security breaches or problems.

NIST-National Institute of Standards and Technology

NIST has long been the clearinghouse for standards and other well-established documents regarding computers and networking. The Computer Security Division of its Information Technology Laboratory evaluates proposed standards and technologies for network and computer security. This division is especially well known for its work in authentication and encryption technologies, fundamentally and as they apply to activities such as Electronic Data Interchange, electronic commerce, and e-mail.

Other resources offered: NIST hosts the Computer Security Resource Clearinghouse, with links to a wide variety of papers, tools, evaluations, and e-mail discussion forums at: http://csrc.nist.gov/

Academic

There are several academic research centers that investigate computer security from both a theoretical and a practical point of view. These centers provide a wide range of information, tools, and services to system administrators, especially in UNIX environments. The following are several of the best known academic centers.

CERT-Computer Emergency Response Team

CERT is located at the Software Engineering Institute of Carnegie Mellon University. SEI was established by the Defense Department's Advanced Research Projects Agency (DARPA) to address a wide range of software issues; CERT's activities are a component of the SEI Survivable Systems Initiative.

CERT is best known for its security advisories, which give specific information regarding security vulnerabilities found in a wide range of operating systems, including the full range of UNIX variants. CERT also issues bulletins regarding viruses and similar attacks.

E-mail: cert@cert.org

Phone: 412-268-7090

Fax: 412-268-6989

Other resources offered: security tutorials, archives, FAQs, and advisory alert e-mail lists

COAST-Computer Operations, Audit, and Security Technology

COAST is a multiple-project, multiple-investigator laboratory in computer security research in the Computer Science Department at Purdue University. It is intended to function with close ties to researchers and engineers in major companies and government agencies. It focuses its research on real-world needs and limitations, with a special focus on security for legacy computing systems. With its recent increase in support and student and faculty participation, COAST is now the largest dedicated, academic computer security research group in the world.

CPSR-Computer Professionals for Social Responsibility

CPSR is a public interest alliance concerned with the impacts of computer technology on society. Their intent is to provide the public and policy makers with objective assessments regarding the power, promise, and limitations of computer technology. CPSR's Web site, hosted by Sunnyside Computing, Inc., provides policy statements on a wide variety of computer topics, including both security and privacy issues. Members are encouraged to participate in local chapters and to effect social activism on computer-related issues.

Where the Hackers Hang Out

Security administrators differ in their attitude to using hacker publications and online sites. Most are uncomfortable taking steps, such as subscribing to a discussion list, that might seem to imply approval of hacker activities.

At the same time, hackers themselves are your best source of information regarding new UNIX vulnerabilities, hacking tools, and other threats to your system. With that in mind, this section lists a few of the more informative sources of information by and about hackers.

Computer Underground Digest

Discusses the computer underground.

Summary

As we've seen, UNIX systems are vulnerable to a number of security risks ranging from inappropriate access to hijacking of system resources and even sabotage.

Fortunately, an equally wide range of information, tools and services is available to administrators who want to defend their systems against misuse. Of these, perhaps the most useful is current information on attacks and defenses. With the increased use of UNIX for corporate computing and network servers, commercial security products are also increasingly powerful and sophisticated.

Security begins with a good set of policies, backed by procedures and the tools with which to implement them. Effective security must balance cost against benefit and usually requires the cooperation and support of the user community and of management. Identifying and responding to system security risks is increasingly one of the system administrator's main responsibilities.
