Several people have asked me what I meant by the "Unix Security Document."
 
I meant David Curry's paper "Improving the Security of Your UNIX
System".
 
I tracked it down again by using swais: source=comp.archives,
keywords=improving security of unix system
 
If you don't have swais or xwais on your system, telnet think.com and
login as wais.

The SRI International white paper, "Improving the Security of Your UNIX
System," may be obtained via the following methods:
 
1. ANONYMOUS FTP
    The document is available via anonymous FTP from the following
    hosts:
 
        (West Coast)    Host: FTP.ERG.SRI.COM
                        Addr: 128.18.4.39
                        File: pub/security-doc.tar.Z
        (West Coast)    Host: GATEKEEPER.DEC.COM
                        Addr: 16.1.0.2
                        File: pub/doc/sri-security-doc.tar.Z
        (East Coast)    Host: UUNET.UU.NET
                        Addr: 192.48.96.2
                        File: doc/security-doc.tar.Z
        (Midwest)       Host: CERT.SEI.CMU.EDU
                        Addr: 128.237.253.5
                        File: pub/info/security-doc.tar.Z
        (Midwest)       Host: TUT.CIS.OHIO-STATE.EDU
                        Addr: 128.146.8.60
                        File: pub/security/security-doc.tar.Z
        (Southwest)     Host: TITAN.RICE.EDU
                        Addr: 128.42.1.30
                        File: sun-source/secdoc.shar.z.uu (uuencoded)
        (MILNET)        Host: WSMR-SIMTEL20.ARMY.MIL
                        Addr: 26.2.0.74
                        File: pd2:<unix-c.info>security-doc.tar-z
        (Australia)     Host: TASIS.UTAS.OZ.AU
                        Addr: 131.217.20.1
                        File: pub/security-doc.tar.Z
        (Australia)     Host: FTP.ADELAIDE.EDU.AU
                        Addr: 129.127.40.3
                        File: pub/misc/security-doc.tar.Z
        (Canada)        Host: CS.TORONTO.EDU
                        Addr: 128.100.1.65
                        File: doc/security-doc.tar.Z
        (Europe)        Host: MCSUN.EU.NET
                        Addr: 192.16.202.1
                        File: documents/security-doc.tar.Z
        (Scandinavia)   Host: FUNIC.FUNET.FI
                        Addr: 128.214.6.100
                        File: pub/doc/security/security-doc.tar.Z
 
    Transfer the file in "binary" mode from all the hosts, except use
    "tenex" mode from SIMTEL-20.  After you get the file, execute
    the commands:
 
        % uncompress security-doc.tar.Z
        % tar xf security-doc
        % cd security-doc
 
    And now consult the README file.
 
    Note: if you get the file from TITAN.RICE.EDU, instead use the commands:
 
        % uudecode secdoc.shar.z.uu
        % uncompress secdoc.shar.Z
        % sh secdoc.shar
        % cd security-doc
 
2. UUCP
    UUNET subscribers can obtain the document via UUCP from UUNET using a
    command of the form
 
        uucp uunet!~/doc/security-doc.tar.Z destination-filename
 
    U.S. sites which do not subscribe to UUNET may still access the document
    by calling the 1-900-GOT-SRCS (468-7727) and logging in as "uucp" with
    no password.  All modems connected to the 900 number are Telebit T2500
    modems supporting PEP, V.32 (9600), V.22bis (2400), Bell 212a (1200),
    and Bell 103 (300).  Use an L.sys line such as:
 
        uunet Any ACU 19200 1-900-468-7727 in:--in:--in: uucp
 
    NOTE: The telephone company will charge you US$0.40/minute for this
          service.  There is no charge directly from UUNET.  At PEP or V.32
          speeds, the document will cost approximately $2.00 in connect time
          (175 kbytes).
    -----
    You can obtain the file via "anonymous" UUCP from Ohio State University
    by placing the following line in your L.sys file:
 
        #
        # Direct Trailblazer
        #
        osu-cis Any ACU 19200 1-614-292-5112 in:--in:--in: Uanon
        #
        # Micom port selector, at 1200, 2400, or 9600 bps.
        # Replace ##'s below with 12, 24, or 96 (both speed and phone number).
        #
        osu-cis Any ACU ##00 1-614-292-31## "" \r\c Name? osu-cis nected \c GO
\d\r\d\r\d\r in:--in:--in: Uanon
 
    and then issue the command
 
        uucp osu-cis!~/security/security-doc.tar.Z destination-filename
    -----
    The document is also obtainable via anonymous uucp access from "sir-alan"
    which supports 19.2K bps PEP (814 337 3159) and 9600 USR HST/V.32
    connections (814 337 0348; send one BREAK after CONNECT 9600).  Login
    is "pdsrc", no password.
 
    Systems/L.sys entries:
 
    sir-alan Any ACU 19200 18143373159 ogin:--ogin:--ogin: pdsrc
    sir-alan Any ACU 9600 18143370348 ogin:-BREAK-ogin:-BREAK-ogin: pdsrc
 
    uucp command:
 
        uucp sir-alan!/u/pubdir/UNIX/security.tar.Z destination-filename
 
    For help, get "sir-alan!/u/pubdir/HELP".
 
3. BITNET
    BITNET users may obtain the document via the European TRICKLE servers
    from the UNIX-SW archives.  To do this, use the TELL command as follows:
 
        TELL TRICKLE AT SOMEHOST /PDGET <UNIX-C.INFO>SECURITY-DOC.TAR-Z
 
    where SOMEHOST is one of:
 
        DKTC11          Denmark
        TREARN          Turkey
        IMIPOLI         Italy
        BANUFS11        Belgium
        AWIWUW11        Austria
        DB0FUB11        Germany
        EB0UB011        Spain
 
    There are no TRICKLE hosts in the U.S.; the Europeans are graciously
    allowing U.S. BITNET users to access their machines.  Please be kind
    to them.  Sorry, but the LISTSERV machines at RPIECS and NDSUVM do
    not provide access to the UNIX-SW repository.
 
    The file will arrive in BITSEND, NETDATA format.  You should use the
    BITRCV command from RDRList to get the file.  (I have no idea what
    this means -- go find an IBM guru if you don't know either.)
 
    This will be a BINARY file.  You won't be able to do much of anything
    with it on an IBM system.  Instead, transfer it to a UNIX system,
    and then uncompress it and extract the tar file, and then format
    things.  See above under "FTP" for how to do this.
 
    NOTE: the connection from the TRICKLEs to SIMTEL-20 has been lousy
    of late.  You may wish to try sending
 
        /PDGET FUNIC.FUNET.FI:disk1/pub/doc/security/security-doc.tar.Z
 
    to LISTSERV@FINTUVM.BITNET instead.
 
4. ELECTRONIC MAIL
    The document may also be obtained from the SUN-SPOTS archive server
    located on host TITAN.RICE.EDU.  In order to request the document,
    send a note with the words
 
        send sun-source secdoc.shar.z.uu
 
    to "archive-server@titan.rice.edu" (uunet!rice!archive-server).
    -----
    The document may be obtained in the United Kingdom from the cam.cl
    info-server in the "sources transient" directory.  Send the message
 
        request sources; topic transient security-doc.tar.Z
 
    to "info-server@uk.ac.cam.cl".  Contact pb@uk.ac.cam.cl for more
    info.
    -----
    If you are an EUnet site, contact your national backbone site.  Many
    of them have set up an info server which you can use, but details
    differ from country to country.
 
5. DECNET
    DECNET users can obtain the file by copying
 
        DECWRL::"/pub/doc/sri-security-doc.tar.Z"
 
    by using the COPY command, or whatever.
 
6. ACSnet (Australia)
    Use "fetchfile" from the host sirius.ua.oz to get the file
    "misc/security-doc.tar.Z".
 
7. USENET
    An "nroff" version of the paper was been posted to the USENET newsgroup
    "comp.doc" on May 7, 1990.  Article id: <13498@ucsd.Edu>
 
8. U.S. MAIL
    As a last resort, you can get a copy from me via U.S. Mail.  To do this,
    send me an 8.5" x 11" self-addressed envelope with US $1.90 in postage
    affixed.  (The document is free, but you have to pay postage - don't
    ask.)  I'll put one in the envelope and send it back to you.
