INSTALLATION --------------- 3.1 - Installation ------------------ PiGAS SECURITY has been tested very extensively in order to be error-free. However, it is recommended to make a system backup before starting the installation. TO INSTALL PiGAS SECURITY - RUN THE INSTALL.EXE PROGRAM AND FOLLOW THE INSTRUCTIONS. 3.2 - List of the new directories structure ------------------------------------------- C:\PIGAS C:\PIGAS\INFO These directories are for internal use. Do not alter their name and their contents. C:\PIGASTST C:\PIGASTST\SMITH C:\PIGASTST\JONES These directories contain demo files. You can delete them whenever you like, but remember to move the files LOGIN.EXE LOGOUT.EXE and PSP.EXE before deleting. C:\PIGASTST\LOGIN.EXE C:\PIGASTST\LOGOUT.EXE All users will use these programs. You can move these programs to any other directory but DO NOT DELETE THEM FROM THE DISK AS LONG AS YOU ARE USING PiGAS SECURITY. C:\PIGASTST\PSP.EXE The master user will use this program (see section 5.) You can move this program to any other directory but DO NOT DELETE IT FROM THE DISK AS LONG AS YOU ARE USING PiGAS SECURITY. 7 PiGAS SECURITY v1.02 User Manual 3.3 - How to Continue from here ------------------------------- Read section 4 - FIRST TIME RUNNING - A SIMPLE EXAMPLE, in order to see how to run the example. 8 PiGAS SECURITY v1.02 User Manual 4. FIRST TIME RUNNING - A SIMPLE EXAMPLE. ----------------------------------------- Let's try an example which will help you in understanding the main features and ideas behind PiGAS SECURITY. When you installed the PiGAS SECURITY, the installation program built the following structures: c:\pigastst - A new directory c:\pigastst\jones.txt - A new file c:\pigastst\smith.txt - A new file c:\pigastst\smith - A new directory c:\pigastst\jones - A new directory c:\pigastst\demo.doc - The demo documentation. c:\pigastst\pigas.doc - The PiGAS SECURITY documentation. c:\pigastst\login.exe - The PiGAS SECURITY login program. c:\pigastst\logout.exe - The PiGAS SECURITY logout program. c:\pigastst\psp.exe - The PiGAS SECURITY configuration program. c:\pigastst\register.doc - Our registration file. c:\pigastst\vendor.doc - Our distribution policy. You can use the commands DIR and TYPE in order to study this structure. In our example there are four different users : 1. You - you are the master user, there is no hidden information from you. 2. Smith - one of the users. Smith HAS ACCESS to the following information: c:\pigastst\demo.doc c:\pigastst\pigas.doc c:\pigastst\login.exe c:\pigastst\logout.exe c:\pigastst\psp.exe c:\pigastst\smith.txt c:\pigastst\smith c:\pigastst\register.doc 9 PiGAS SECURITY v1.02 User Manual c:\pigastst\vendor.doc Smith HAS NO ACCESS to the following information: c:\pigastst\jones.txt c:\pigastst\jones 3. Jones - one of the users. Jones HAS ACCESS to the following information: c:\pigastst\demo.doc c:\pigastst\pigas.doc c:\pigastst\login.exe c:\pigastst\logout.exe c:\pigastst\psp.exe c:\pigastst\jones.txt c:\pigastst\jones c:\pigastst\register.doc c:\pigastst\vendor.doc Jones HAS NO ACCESS to the following information: c:\pigastst\smith.txt c:\pigastst\smith 4. Others - Anyone who is trying to use the computer without your permission, HAS ACCESS to the following information: c:\pigastst\demo.doc c:\pigastst\pigas.doc c:\pigastst\login.exe c:\pigastst\logout.exe c:\pigastst\psp.exe c:\pigastst\register.doc c:\pigastst\vendor.doc and HAS NO ACCESS to the following information: c:\pigastst\smith.txt c:\pigastst\smith c:\pigastst\jones.txt c:\pigastst\jones 10 PiGAS SECURITY v1.02 User Manual The install program built the necessary setup for these users and gave each user an id and a password as follows: For you - the user id is master and the password is masterp For smith - the user id is smith and the password is 12345678 For jones - the user id is jones and the password is 87654321 For others - there is no special setup. A. First, we will hide all the confidential information. Type : LOGOUT Now everybody has access only to: demo.doc pigas.doc login.exe logout.exe psp.exe register.doc vendor.doc but no access to: smith.txt smith jones.txt jones WARNING ------- You will not succeed accessing the hidden files and directories, even if you try to boot the computer, or use a sophisticated disk utility . B. Suppose Smith wants to start a session. He will type: 11 PiGAS SECURITY v1.02 User Manual LOGIN >smith 12345678 Now Smith has only access to: demo.doc pigas.doc login.exe logout.exe psp.exe smith.txt smith register.doc vendor.doc and has no access to the following information: jones.txt jones Once Smith has finished his work - and before turning off the computer - he should type: LOGOUT Again, all the confidential information becomes hidden. C. Suppose Jones wants to start a session. He will type: LOGIN >jones 87654321 Now Jones should have access only to: demo.doc pigas.doc login.exe logout.exe psp.exe jones.txt 12 PiGAS SECURITY v1.02 User Manual jones register.doc vendor.doc and not be able to access the following information: smith.txt smith Once Jones has finished his work - and before turning off the computer - he should type: LOGOUT Again, all the confidential information becomes hidden. C. Suppose that YOU (the master user) want to start a session. Type: LOGIN >master masterp You will have access to all the information: demo.doc pigas.doc login.exe logout.exe psp.exe jones.txt jones smith.txt smith register.doc vendor.doc D. Any other user has no reason for using the Login program. If he tries and enters a wrong user id or password, the Login program will call the Logout program which will hide all confidential information. In this chapter we demonstrated the daily use of the PiGAS SECURITY - 13 PiGAS SECURITY v1.02 User Manual using the Login and Logout programs in order to start, and end,a session. However, the "master user" (you) should also need to know how to create, change or delete a user setup. This is done using the PSP program and it is explained in the next chapter. Before continuing, make sure to log in as master by typing: LOGIN >master masterp IMPORTANT : ----------- All other users cannot use the PSP program. 14 PiGAS SECURITY v1.02 User Manual 5. HOW TO PROTECT OBJECTS ------------------------- In order to protect objects in the computer, you should first define the computer users and their restricted objects. (Note : In this SHAREWARE version, objects refer to files and directories.) In the PiGAS SECURITY program, computer users are divided in two categories - MASTER USER - NORMAL USER A "MASTER USER" is a user who has access to all the objects in the computer, whereas a "NORMAL USER" refers to users who have a restricted access to some objects in the computer. Thus, PiGAS SECURITY contains three different programs : - PSP.EXE - LOGIN.EXE - LOGOUT.EXE PSP.EXE can be used only by the "MASTER USER" in order to create, change or delete a user setup. (Section 5.1 describes this program.) LOGIN.EXE can be used by a "NORMAL USER" and a "MASTER USER" in order to start a session. (Section 5.2 describes this program.) LOGOUT.EXE can be used by a "NORMAL USER" and a "MASTER USER" in order to end a session. (Section 5.2 describes this program.) 5.1 SETUP PROTECTION FOR OBJECTS (PSP.EXE program) -------------------------------------------------- In order to protect objects in the computer, the MASTER USER (you) defines the different users and their access/restriction list. This is done by the PSP.EXE program, which allows the MASTER USER to create, change, or delete the user configuration. 5.1.1 STARTING THE PSP PROGRAM ------------------------------ To start the PSP program, simply type : PSP 15 PiGAS SECURITY v1.02 User Manual (We assume that the current directory is C:\PIGASTST) The MAIN MENU appears. Press to have access to the setup options. The following sections will explain in detail each option of the program. 5.1.2 CREATING THE USER SETUP ----------------------------- To create the user setup, press from the main menu. A dialog box appears. (Note : For your convenience, you can see in the dialog box a list of all the existing user names that you cannot select.) Type the new user name (4 to 8 characters maximum: from a to z, numbers are allowed) and press . The USER SETUP appears. (Section 5.1.4 describes how to use the USER SETUP and how to define the user password.) 5.1.3 CHANGING THE USER SETUP ----------------------------- To change the user setup, press from the main menu. A dialog box appears. Select the user name by placing the cursor on a name from the list in the dialog box and press . The USER SETUP appears. (Section 5.1.4 describes how to use the USER SETUP.) 5.1.4 USER SETUP ---------------- The USER SETUP contains the following elements: 1. User Name - displays the user name and allows to change it. In order to change the user name, place the cursor on the user name field by pressing . Then type the new user name. In case you are changing an old user name to a new one, the program will create a new copy for the new user name. The old user setup will not be deleted. 16 PiGAS SECURITY v1.02 User Manual A User name can contain from 4 to 8 characters maximum, from a to z (numbers can be included). 2. Password - displays the user password and allows to change it. In order to change the user password, place the cursor on the user password field by pressing . Then type the new user password. The User Password can contain from 6 to 11 printable characters (with case sensitivity). 3. Dir Tree - displays all the directories of a drive and allows to add or remove protection for the directories. In order to activate this window, press . Adding or removing a protection to a directory ---------------------------------------------- IMPORTANT: DO NOT PROTECT A DIRECTORY WHICH CONTAINS ---------- LOGIN.EXE OR LOGOUT.EXE Use the or to place the cursor on the selected directory. Press <+> on the numeric pad in order to add a protection to the directory. Press <-> on the numeric pad in order to remove a protection to the directory. (Note : A protected directory will always be displayed in parentheses.) Changing current drive displayed in directory tree menu ------------------------------------------------------- In order to change the current drive, press then select from the list the new drive by placing the cursor on it. Press again. 4. File list - displays the files list and allows to add or remove protection for the files. In order to activate this window, press . Adding or removing a protection to a file ----------------------------------------- 17 PiGAS SECURITY v1.02 User Manual IMPORTANT: DO NOT PROTECT THE FILES: ---------- LOGIN.EXE, LOGOUT.EXE. Use the or to place the cursor on the selected file. Press <+> on the numeric pad in order to add a protection to a file. Press <-> on the numeric pad in order to remove a protection to a file. (Note : A protected file will always be displayed in parentheses.) 5. Dir name - displays the current directory name and allows to change it. In order to change the current directory, press then type the new directory name and press or . If you do not type a full path name, the first directory that matches the dir name field will become the current directory. 6. File name - selects the file name to be displayed. In order to change the file name to be displayed, press then type the new file name and press or . 7. Cancel - in order to quit this menu without saving the last changes, press or . 8. OK - press in order to save all the changes and quit. 9. Show - is used after changing the dir name field or the file name field as described above for elements #5 and #6. 10. Select Drive - is used to change the default drive for the directory tree menu as described above for element #3. 5.1.5 DELETING THE USER SETUP ----------------------------- To delete the user setup, press from the main menu. A dialog box appears. Select the user name by placing the cursor on a name from the list in the dialog box and press . A confirmation message appears. Press to confirm the delete operation or and in order to cancel it. 18 PiGAS SECURITY v1.02 User Manual 5.1.6 MASTER PASSWORD --------------------- To have access to the master password, press from the main menu. The message "CHANGE MASTER PASSWORD" appears. Type a new master password from 6 to 11 printable characters (with case sensitivity). and press . The message "ENTER MASTER PASSWORD AGAIN " appears. Type the new master password again and press . (Note : Entering the new password again is done in order to make sure that no mistake has been made while typing the password.) It is recommended to change the default password - masterp. PLEASE REMEMBER THIS PASSWORD; OTHERWISE, YOU WILL NOT HAVE THE ABILITY TO HAVE ACCESS TO THE PROTECTED OBJECTS. 5.1.7 ENCRYPTION METHOD ----------------------- To select the encryption method, press then from the main menu. A dialog box appears. The Fast option - allows Fast encryption during the Login program. Fast is the default option. The Secure option - allows a better security encryption method during the Login program (at the expense of speed). Press to select Fast. Press to select Secure. After selecting the encryption method, press . 5.1.8 GENERAL REPORT -------------------- To produce a general report, press from the main menu. A report about all the users appears. Use the or to read the report. 19 PiGAS SECURITY v1.02 User Manual Press to exit from the report. 5.1.9 USER REPORT ----------------- To produce a user report, press from the main menu. A dialog box appears. Select the user name by placing the cursor on a name from the list in the dialog box and press . A report about the selected user appears. Use the or to read the report. Press to exit from the report. 5.1.10 HIDDEN FILES/DIRECTORIES REPORT -------------------------------------- To obtain a report about all the hidden files and directories on the screen, press from the main menu. Use the or to read the report. Press to exit from the report. 5.1.11 LOG REPORT ----------------- To generate a log report on the screen, press then from the main menu. A log report about all the calls to LOGIN.EXE and LOGOUT.EXE appears. Use the or to read the report. Press to exit from the report. 5.1.12 DELETE LOG ----------------- To delete the log report, press then from the main menu. A confirmation message appears. Press to continue the delete operation or and in order to cancel it. 5.1.13 EXITING FROM THE PROGRAM ------------------------------- 20 PiGAS SECURITY v1.02 User Manual To exit from the program, press from the main menu. 5.1.14 REMARKS -------------- - All the internal information of the program is kept under the directories c:\pigas and c:\pigas\info. DO NOT ALTER THE NAMES AND CONTENTS OF THESE DIRECTORIES. - The pigas directories (c:\pigas and c:\pigas\info) are protected by default and are not accessible to all the NORMAL USERS. You can remove this protection (see section USER SETUP) but a user cannot have any protected object without having a protection on the pigas directories. (When that happens, the PSP program will automatically add a protection to the user setup on the pigas directories.) 5.2 RUNNING THE PROTECTION (LOGIN.EXE and LOGOUT.EXE programs) -------------------------------------------------------------- After creating the user's configuration, as explained in section 5.1, each user can use the LOGIN.EXE program, together with his user name and password in order to start a working session, and the LOGOUT.EXE program in order to end a working session. LOGIN.EXE - used to start a user session. It protects the objects according to the user's configuration. You can execute LOGIN.EXE in two different ways : 1. Enter directly the parameters (user name and password): login or 2. Call the program without parameters. The system will prompt you for the user name and password. (Note : This method is more secure because the password does not appear 21 PiGAS SECURITY v1.02 User Manual on the screen). Login Login 1.02 SHAREWARE, Copyright (c) 1993 by PiGAS Inc. > LOGOUT.EXE - used to end a user session. It protects ALL the objects that were selected by PSP.EXE. To execute LOGOUT.EXE, simply type: Logout IMPORTANT --------- 1. The MASTER USER can start a session as follows: Login Login 1.02 SHAREWARE, Copyright (c) 1993 by PiGAS Inc. > master masterp If you changed the MASTER USER password, type: Login Login 1.02 SHAREWARE, Copyright (c) 1993 by PiGAS Inc. > master 2. Any time a user enters the wrong user id or password, ALL the objects that were selected by PSP.EXE become protected. 3. It is recommended to put a call to LOGIN.EXE or LOGOUT.EXE in the autoexec.bat file. Any attempt to enter a wrong user id or password (or entering an empty user id by pressing ) during the system boot will automatically protect ALL the selected objects. 3. The following call: Login 22 PiGAS SECURITY v1.02 User Manual Is equivalent to Logout 4. The best way to start - and to end - a user session is, as follows: - Start the session by calling LOGIN.EXE: Login user1 password1 (do your work .....) - End the session by calling LOGOUT.EXE: Logout All selected objects will be protected. 23 PiGAS SECURITY v1.02 User Manual 6. SUGGESTED PROTECTION STRATEGY -------------------------------- This chapter will help you define your own protection strategy. We assume that you have read the chapter HOW TO PROTECT OBJECTS. To define your own protection strategy you need to decide: 1. From which persons (users) you want to hide the information. 2. Which information (files and directories) you want to hide from each one of the users. When you think about these problems, normally you will come up with three "GROUPS" or "TYPES" of users: 1. "ANY USER" TYPE - These are users whom you do not want to work on your computer. For example: people in your office who pass near your computer and "accidentally" snoop on your data. It is up to you to decide which information these people can, or cannot, see. If you want, you can hide all the directories on the disks, but normally you are only worried about your personal data, and you do not mind if someone has access to other common utilities on the disk. Again it is up to you to decide. 2. "MASTER USER" TYPE - This is you. You have access to all the information in the disk. 3. "SPECIAL USER" TYPE - This refers to other people who can have more access than ANY USER, but less access than the MASTER USER. You can have different users here. Having these three groups in mind, it is quite simple to decide for each group which file(s) and directory(ies) needs to be protected or not. Now you can create the users' configuration. 1. For the "ANY USER" TYPE. You create a new user (by using the PSP program). For example: user name: ANYUSER and password: DONTCARE. Then you mark the restricted files and directories. 24 PiGAS SECURITY v1.02 User Manual From that point on, anytime someone (master user or "special user") types LOGOUT (or logs in with the wrong password), all the files and directories that have been selected as such will be unavailable. 2. For the MASTER USER, the configuration is ready and does not need to be changed (except for the MASTER password, if you want). 3. "SPECIAL USERS" - For each special user, you create a new user setup and select the hidden files and directories for him. If you have many users with the same configuration, you can give to all of them the same name and password so you do not need to copy the configuration. 25 PiGAS SECURITY v1.02 User Manual 7. OPTIMIZATIONS ---------------- 7.1. SPEED ---------- Try to avoid "nested encryption" in the user setup. It works fine, but causes an unnecessary overhead. For example, if you have the following disk structure : c:\example c:\example\one c:\example\one\file c:\example\two c:\example\two\file and you select only "c:\example" to be hidden: c:-- | | --(example) All the subdirectories and files of "c:\example" also become hidden for this user. It is unnecessary to select each one to be hidden. On the other hand, sometimes it is necessary to use "nested encryption". For example, if you have the following disk structure : c:\example - a directory c:\example\one - a directory c:\example\one\file - a file By selecting only the directory "c:\example" to be hidden, as explained above, "c:\example\one" and "c:\example\one\file" will also become unavailable. However, someone may try to use some low level disk utilities and find some sectors that contain the information in the file "c:\example\one\file". To avoid this, you also need to select the "c:\example\one\file" to be hidden (and to select the secure protection method in the dialog box protection method). 26 PiGAS SECURITY v1.02 User Manual You do not need to use a "nested encryption" if you do not suspect that someone is going to spend a few hours working on your computer in order to decrypt your data. But if your data is very sensitive, it is recommended to use the "safe" solution of nested encryption. 7.2 DISK SPACE -------------- The login.exe and logout.exe programs are identical. You can save some disk space by deleting the logout.exe. In this case, the user will log out by typing : LOGIN . 27 PiGAS SECURITY v1.02 User Manual 8. CONFLICTS WITH OTHER UTILITIES --------------------------------- Some low level disk utilities (like CHKDSK.COM, NDD.EXE, etc.) might report the hidden information as a disk problem and ask if you want to correct these problems. BEFORE LETTING THE UTILITIES CORRECT THE DISK, YOU MUST BE SURE THAT YOU ARE THE MASTER USER. This can be done by: 1. log in as a master user or 2. try to access "c:\pigas" - which is accessible only to the master user. To help you avoid this conflict, PiGAS SECURITY will automatically hide these low level disk utilities from the normal user. So if a user did not log in as a master user, he will not able to run these utilities. However, you, as a master user, can run these utilities and obtain the correct results as required. AGAIN - BEFORE LETTING ANY PROGRAM CORRECT DISK ERRORS, BE SURE THAT YOU HAVE LOGGED IN AS MASTER USER. REMARK : The automatic hiding is done as follows: During the installation, a special scan routine searches in the disk for all the known utilities that might have a conflict with PiGAS SECURITY, and creates a file ("c:\pigas\info\conflict.dat") that contains a list of all the utilities that have been found. Then, each time you create or change a user configuration, all these utilities are added to the protected files list for this user. ADDING FILES TO THE AUTOMATIC HIDDEN LIST There might be utilities that have not been added automatically to the file "conflict.dat" (utilities that are not in the list of the install program.). You can add these utilities to "conflict.dat" by 28 PiGAS SECURITY v1.02 User Manual using any text editor - and typing their full path. After updating the file "conflict.dat", call the program PSP.EXE once. Type: PSP /u The PSP program will update automatically all the users' setup. 29 PiGAS SECURITY v1.02 User Manual 9. RESTORING THE LOGIN.EXE AND PSP.EXE FILES -------------------------------------------- You can always restore the LOGIN.EXE and PSP.EXE files from the original diskette of PiGAS SECURITY: Insert the PiGAS SECURITY in drive A. Type: COPY A:PIGAS.01 C:LOGIN.EXE COPY A:PIGAS.02 C:PSP.EXE 30 PiGAS SECURITY v1.02 User Manual 10. REGISTRATION AND TECHNICAL SUPPORT -------------------------------------- In order to register the PiGAS SECURITY, fill in the REGISTRATION FORM. FRENCH, BELGIAN and SWISS users can register through the DP Tool club using the FRENCH REGISTRATION FORM. Once you are registered, you will receive a receipt, a registration number, and you will benefit from the following advantages : 1. A registered version of PiGAS SECURITY with a UNIQUE INTERNAL KEY !. This unique key provides another level of security : even if someone discovers the encryption method of the unregistered version, he will still need to know your unique internal key in order to decrypt your data. The registered and unregistered versions are the same in terms of operation and speed (but the registration reminder screens will not appear on the registered version ...). 2. A C++ source code of PiGAS FILE ENCRYPTION program. This is the source code of a fully functional and powerful file encryption program (different from the encryption method used in PiGAS SECURITY). The registered user can use the code to create a file encryption program (simple compilation and linking needed) or link it with his own application. 3. A printed manual. The user manual contains a special article about computer security and encryption methods that does not exist in the PiGAS.DOC. 4.
