- Understanding Security Levels In HDM IV Version 3 & 4
-
- Hard Disk Menu IV version 3/4 offers a greatly expanded security
- system compared to earlier versions. This is especially useful in
- a business environment or on systems that are running a network.
- When many users are involved and/or there is a need for security,
- HDM's expanded security options can be very useful.
-
- We recognize that many new or inexperienced users might find the
- advanced security options a bit confusing. To enhance your
- enjoyment of HDM and to eliminate frustration, this special
- section is designed to explain the security options so that they
- can be easily used and understood. We'll examine the Master
- Password Table, the User ID Table, and see how they work by using
- examples.
-
-
- SECURITY OR NOT?
-
- In setting up HDM the first thing you should decide is if you
- want or need to use the security options. This is a case where
- YOU have to analyze how your system is setup, who uses it, how
- much experience they have, and the like.
-
- You may want to run a completely "open" system. This would mean
- that individual users would not log on using a password. All
- users would use the same menus and have the same selections. It
- would also mean that any and all users could access the Top Menu,
- change menu options, Timed Execution, and so on. This would be a
- system with no restrictions of any kind. Having this type of HDM
- setup would generally assume that all users of the system were
- "computer literate" -- that all users were comfortable with DOS
- commands, etc. It would also assume that all users wanted to work
- with the same menus, have the same colors, etc.
-
- HDM comes with ALL security levels set to a default of "00". If
- you want to have a totally "open" system than you need not change
- any of the security levels. You will not need to use the Master
- Password Table or the User ID Table.
-
-
- SECURING YOUR SYSTEM
-
- Another type of setup would be one that we could call "partially
- secure." Perhaps this is a home computer that the family uses.
- You are the primary user and the one who is setting up HDM. The
- other members of the family are not comfortable with DOS
- commands, directory structures, and the like. In this instance,
- you might setup different menus for different family members. A
- set of menus for yourself, another set for your wife/husband, and
- another set for your children. Each user would log on and get
- their own personalized menu.
-
- You might also want to restrict their access to the Top Menu --
- so that nothing could be altered accidentally. In effect, you
- would be a "system manager" and would create a friendly HDM
- environment for the rest of the family. This is a common type of
- setup.
-
- Let's take this last scenario and break it down into simple terms
- as it relates to HDM's enhanced security functions.
-
-
- THE MASTER PASSWORD TABLE
-
- Load HDM and press F10 to access the Top Menu. Press "S" to
- access the Security options. If you press "M" you'll access the
- Master Password Table. This table displays the numbers 1 through
- 99 and allows you to have 99 different "security levels." The key
- to working with "security levels" is this:
-
- "With any given security level you can access all things that
- have a security level equal to or LESS than your own. You can NOT
- access any item that has a security level GREATER than your own."
-
- Thus, if you give yourself a security level of 50, you can access
- ANYTHING that has a security level of 50 or below. If you gave
- the Top Menu a security level of 99, YOU would NOT be able to
- access it! From the Master Password Table let's see how to set up
- HDM safely for the "family" in the scenario mentioned above.
-
-
- SETTING UP SECURITY
-
- Based on the assumption that you are setting up HDM and that you
- will be the "system manager" for our hypothetical family, enter
- 99 at the Master Password Table. You will be prompted for a
- password. Enter a password that you will remember, but that no
- one else will easily guess. You will be asked to enter the
- password again to verify that there was no mistake. A password is
- now "set" for security level 99. To access anything that has that
- security level, a person would have to know the password that you
- just assigned to level 99.
-
- Access the Security section of the Top Menu again. Select "U" to
- access the User ID Table. Enter a user name for yourself. Your
- next option is to enter the number of the menu page that you
- start at. You can then enter a menu entry that you want to
- automatically run each time you access HDM. Next you assign
- yourself a security level. Since you are to be the 'system
- manager', give yourself a 99. In this way you insure that you can
- access ANYTHING because there is no higher security level. Your
- last option is to set a logon password. Using our example, you
- would select a logon password for yourself. Once again you will
- be requested to enter it again to make sure that there is no
- error.
-
- NOTE: Each individuals logon password is totally independent of
- the password assigned to their particular security level. For
- example, say you assigned a password of TEST to security level 99
- in the Master Password Table. You can select any password you
- like for your personal logon password. The password of TEST is
- only needed to access functions that are protected by a security
- level of 99. By using varying security levels you can restrict
- what the other users can see and do. An example might be helpful.
-
- Still using our 'family' scenario, let's say that you gave your
- wife/husband a security level of 90 and each of your children a
- security level of 50 when you set them up in the User ID Table.
- The table might look like this:
-
- ╔══════════════════════════════════════════════════════════════╗
- ║ User Identification │ Menu File │ Run! │ Security │ Password ║
- ╠══════════════════════════════════════════════════════════════╣
- ║ Bob │ 300 │ │ 99 │ √ ║
- ║ Brenda │ 299 │ A1 │ 90 │ √ ║
- ║ Melissa │ 150 │ A5 │ 50 │ √ ║
- ║ Kathy │ 100 │ B7 │ 50 │ √ ║
- ║ │ │ │ │ ║
- ║ │ │ │ │ ║
- ║ │ │ │ │ ║
- ║ │ │ │ │ ║
- ║ │ │ │ │ ║
- ║ │ │ │ │ ║
- ╠══════════════════════════════════════════════════════════════╣
- ║ Enter=Change Esc=Cancel F2=Save Ins=Add Del=Delete ║
- ╚══════════════════════════════════════════════════════════════╝
-
-
- You can see that each user has their own menu pages, each has a
- different security level, and each has a logon password. You
- might also note that everyone but you (the system manager) has a
- menu entry that is automatically run when HDM is started. Now,
- let's see how security levels can be used to restrict use of
- certain items.
-
- Let's say that in the security section of the Top Menu you
- selected "Hide/Disable Top Menu" and assigned it a security level
- of 20. (Remember, in order to do this you would have had to set a
- security level 20 password in the Master Password Table) At the
- same time you also selected "Top Menu: All Commands" and gave it
- a security level of 80. What effect would this have?
-
- With a security level of 50 your children could press F10 and see
- all of the items on the Top Menu. This is because the security
- level that 'hides' it is only 20. If they tried to actually
- select an item, however, they would see this:
-
- ╔═══════════════════════════════╗
- ║ Security Level 80 ║
- ╠═══════════════════════════════╣
- ║ Enter Password [__________] ║
- ╠═══════════════════════════════╣
- ║ Enter=OK Esc=Cancel Ins 1 ║
- ╚═══════════════════════════════╝
-
- This is because all of the Top Menu commands are protected by a
- security level of 80. Thus, only you and your spouse, with
- security levels of 99 and 90 respectively, could actually change
- things via the Top Menu. To totally hide the Top Menu from your
- children all you would have to do is to raise the security level
- for "Hide/Disable Top Menu" to a level greater than 50 -- the
- level held by your children. If you did this your children would
- not even see the Top Menu, nor would they see the "F10=Menu" at
- the bottom of the HDM screen. It would be invisible to them. You
- and your spouse, on the other hand, could access the Top Menu at
- will whenever either of you logs on.
-
-
- SUMMING IT UP
-
- Hopefully you can see how security levels can be used to restrict
- access to only selected individuals. A good way to go about it is
- to sit down and take a moment to plan out the level of security
- that you want on your system. Determine if you want to restrict
- access to the Top Menu, for example, by certain users. Decide
- what security levels you want to use. In our example we set
- security levels 20, 50, 80, 90, and 99. Once you have a plan, go
- to the Master Password Table and 'set' the security levels that
- you've decided on. You might want to jot down the passwords you
- assign and keep them in a safe place. Once this is done you can
- proceed to the User ID Table and create 'accounts' for all of
- your users. Give security levels that are appropriate for each
- user. With that accomplished you can go on to restrict access to
- sensitive areas like the Top Menu using the security levels that
- you created. One last thing.
-
- Remember that "security levels" are just numbers. You could
- accomplish the same things outlined in our scenario without
- assigning a security level greater than 6. How? By using lower
- numbers. For example, you could set the following security levels
- rather than the ones we used:
-
- Hide/Disable Top Menu = Security Level 1
- Childrens Security Level = 2
- Top Menu: All Commands = Security Level 3
- Spouse Security Level = 4
- Your Security Level = 5
-
- Set up YOUR system in a way that makes sense to you. Remember the
- basic rule about security levels, which is:
-
- "With any given security level you can access all things that
- have a security level equal to or LESS than your own. You can NOT
- access any item that has a security level GREATER than your own."
-
- Because HDM now offers 99 security levels does not mean that you
- have to use them all. Plan the level of security that you want
- and then implement it. If it helps, follow the 'family' scenario
- given above. If you are puzzled and in doubt, ALWAYS set yourself
- at the highest security level, 99. In this way you'll never be
- locked out of anything and you can always make corrections.
-
- We hope that this section has been helpful. It has been intended
- to help new or inexperienced users who are unfamiliar with
- setting up security levels. Business users and others will find
- HDM's new enhanced security system even more helpful for
- restricting usage throughout their systems. With HDM you can
- restrict usage to individual menu entries, entire pages, and even
- prevent menu pages from being altered.
