Recital 10 introduced the PIPETOSTR() function. This function operates in a similar fashion to the FILETOSTR() function but it can be used to capture the output from externally executed operating system commands. e.g.
// determine how many Recital users are on the system
nusers = pipetostr("ps -ef | grep db.exe | wc -l")

This article discusses Recital database security: from operating system file permissions through file and field protection to DES3 encryption.

Overview

A company's data is extremely valuable and must be protected, both in operation and in physical file format. Recital products provide a range of ways to protect your data.

Operating System File Permissions

The most basic level of database security is provided by the operating system. Recital database tables and indexes are individual files with their own respective operating system file permissions. Read permission is required to open a table and write permission to update a table. If a user does not have read permission they are denied access. Without write permission, a table will be opened read-only.

Here the owner, root, and members of the recital group have write permission, so can update the example table unless additional protection applies. Other users can only open the example table read-only.

# ls -l example*
-rwxrwxr-x    1 root     recital       147 Nov 29 14:27 example.dbd
-rwxrwxr-x    1 root     recital     41580 Nov 29 14:27 example.dbf
-rwxrwxr-x    1 root     recital     13312 Nov 29 14:28 example.dbt
-rwxrwxr-x    1 root     recital     19456 Nov 29 14:28 example.dbx

Note: As in the example above, a table's associated files should have the same permissions as the table itself:

File Extension

File Type

.dbd

Dictionary

.dbf

Table

.dbt

Memo

.dbx

Index


Database Dictionary

Each Recital table may have a Database Dictionary. The Dictionary can be used both to protect the integrity of the data and to protect access to the data. This section covers Column Constraints, Triggers, Security and Protection.

Column Constraints: Data Integrity

The Dictionary attributes or constraints either prevent the entry of incorrect data, e.g. must_enter and validation or aid the entry of correct data, e.g. default, picture and choicelist. The Dictionary can be modified in the character mode CREATE/MODIFY STRUCTURE worksurface, via SQL statements, or in the Recital Enterprise Studio Database Administrator.

Fig 1: MODIFY STRUCTURE Worksurface: Dictionary.

The SQL Column Constraints are as follows:

Constraint

Description

AUTO_INCREMENT | AUTOINC

Used to auto increment the value of a column.

CALCULATED

Used to calculate the value of a column.

CHECK | SET CHECK

Used to validate a change to the value of a column.

DEFAULT

Used to set a default value for the specified column.

DESCRIPTION

Used set the column description for the specified column.

ERROR

Used to define an error message to be displayed when a validation check fails.

FOREIGN KEY

Used to define a column as a Foreign Key for a parent table.

NOCPTRANS

Used to prevent code page translation for character and memo fields.

NOT NULL | NULL

Used to disallow/allow NULL values.

PRIMARY KEY

Used to define a table’s Primary Key.

RANGE

Used to specify minimum and maximum values for a date or numerical column.

RECALCULATE

Used to force recalculation of calculated columns when a column’s value changes.

REFERENCES

Used to create a relationship to an index key of another table.

UNIQUE

Used to define the column as a candidate index for the table


These can be specified in CREATE TABLE or ALTER TABLE statements:

exec sql
  OPEN DATABASE southwind;
exec sql
  ALTER TABLE customers ADD COLUMN timeref char(8) CHECK validtime(timeref)
  ERROR "Not a valid time string";

TRIGGERS

Table Level Triggers are event-driven procedures called before an I/O operation. These can be used to introduce another layer of checks before a particular operation is permitted to take place or to simply set up logging of those operations.

The CREATE/MODIFY STRUCTURE worksurface <TRIGGERS> menu bar option allows you to specify table level triggers. You may edit a trigger procedure from within the <TRIGGERS> menu by placing the cursor next to the procedure name and pressing the [HELP] key. A text window pops up for editing. If the table triggers are stored in separate <.prg> files, rather than in a procedure library, procedures need not be predefined (SET PROCEDURE) before using the table.

Fig 3: MODIFY STRUCTURE Worksurface: Triggers.

 

The following triggers can be selected and associated with a specified procedure name in the <TRIGGERS> menu.

Trigger

Description

UPDATE

The specified procedure is called prior to an update operation on the table. If the procedure returns .F., then the UPDATE is canceled.

DELETE

The specified procedure is called prior to a delete operation on the table. If the procedure returns .F., then the DELETE is canceled.

APPEND

The specified procedure is called prior to an append operation on the table. If the procedure returns .F., then the APPEND is canceled.

OPEN

The specified procedure is called after an open operation on the table.

CLOSE

The specified procedure is called prior to a close operation on the table.

ROLLBACK

The specified procedure is called when a user presses the [ABANDON] key in a forms based operation.


The Recital Enterprise Studio Database Administrator also allows you to associate existing programs as Table Trigger Procedures.

Fig 4: Database Administrator: Triggers.

 

Programmatically, Trigger Procedures can also be associated with a table using SQL. The following table constraints may be applied in the SQL CREATE TABLE and ALTER TABLE statements:

Trigger

Description

ONUPDATE

The specified procedure is called prior to an update operation on the table. If the procedure returns .F., then the UPDATE is canceled.
e.g. SQL> ALTER TABLE customer modify ONUPDATE "p_update";

ONDELETE

The specified procedure is called prior to a delete operation on the table. If the procedure returns .F., then the DELETE is canceled.
e.g. SQL> ALTER TABLE customer modify ONDELETE "p_delete";

ONINSERT

The specified procedure is called prior to an insert operation on the table. If the procedure returns .F., then the INSERT is canceled.
e.g. SQL> ALTER TABLE customer modify ONINSERT "p_insert";

ONOPEN

The specified procedure is called after an open operation on the table.
e.g. SQL> ALTER TABLE customer modify ONOPEN "p_open";

ONCLOSE

The specified procedure is called prior to a close operation on the table.
e.g. SQL> ALTER TABLE customer modify ONCLOSE "p_close";

ONROLLBACK

The specified procedure is called when a user presses the [ABANDON] key in a forms based operation.
e.g. SQL> ALTER TABLE customer modify ONROLLBACK "p_rollback";


SECURITY

As mentioned above, all Recital files are subject to Operating System read and write permissions. These permissions can be further refined, while still using the Operating System user and group IDs, in the Security and Protection sections of the Dictionary. The Security section handles table based operations and the Protection section focuses on individual fields.

Security and Protection rules can be defined in the CREATE/MODIFY STRUCTURE worksurface of Recital Terminal Developer, via the SQL GRANT and REVOKE statements or in the Recital Enterprise Studio Database Administrator.

Fig 5: MODIFY STRUCTURE Worksurface: Security.

 

The Security section has table operations for which Access Control Strings can be specified. An Access Control String (ACS) is a range of valid user identification codes, and is used to restrict table operations to certain individuals or groups. Each user on the system is allocated a group number and a user number. The user identification code is the combination of group and user numbers. When constructing an Access Control String of linked user identification codes, wild card characters may be used.

Example ACS

Description

[1,2]

In group 1, user 2

[100,*]

In group 100, all users

[2-7,*]

In groups 2-7, all users

[*,100-200]

In all groups, users 100-200

[1,*]&[2-7,1-7]

In group 1, all users, in groups 2-7, users 1-7


Please note that the maximum ACS length is 254 characters. OpenVMS group and user numbers are stored and specified in octal. On other Operating Systems, group and user numbers are stored and specified in decimal.

Access Control Strings may be associated with the following operations:

Operation

Description

READONLY

Users specified in the ACS have read-only access to the table. All other users have update access.

UPDATE

Users specified in the ACS have update access to the table. All other users are restricted to read-only access.

APPEND

Users specified in the ACS can append records into the table. No other users can append.

DELETE

Users specified in the ACS can delete records from the table. No other users can delete.

COPY

Users specified in the ACS can copy records from the table. No other users can copy.

ADMIN

Users specified in the ACS can use the following commands:
SET DICTIONARY TO
MODIFY STRUCTURE
PACK
ZAP
REINDEX
All other users cannot, except the creator of the table, who is always granted ADMIN access.


The corresponding SQL privileges are:

Operation

Description

SELECT

Users specified in the ACS may name any column in a SELECT statement. All other users have update access.

UPDATE

Users specified in the ACS may name any column in an UPDATE statement. All other users are restricted to read-only access.

INSERT

Users specified in the ACS can INSERT rows into the table. No other users can INSERT.

DELETE

Users specified in the ACS can DELETE rows from the table. No other users can DELETE.

ALTER

Users specified in the ACS can use the ALTER TABLE statement on this table.

READONLY

Users specified in the ACS may read any column in a SELECT statement. All other users have update access.


// Grant insert privilege for the customer table
exec sql
  OPEN DATABASE southwind;
exec sql
  GRANT UPDATE (lastname, firstname)
  INSERT ON customers
  TO '[20,100]'; 
	
// Grant all privileges to all users
exec sql
  OPEN DATABASE southwind;
exec sql
  GRANT ALL 
  ON shippers TO PUBLIC;

PROTECTION

Security and Protection rules can be defined in the CREATE/MODIFY STRUCTURE worksurface of Recital Terminal Developer, via the SQL GRANT and REVOKE statements or in the Recital Enterprise Studio Database Administrator.

Fig 6: Database Administrator: Protection.

 


The format of the ACS is the same as in <SECURITY> above. The following protection can be defined:

Operation

Description

READONLY

Users specified in the ACS have read-only access to the field. All other users have update access.

UPDATE

Users specified in the ACS have update access to the field. All other users are restricted to read-only access.


Recital Terminal Developer also has 'HIDDEN' Protection:

Operation

Description

HIDDEN

Users specified in the ACS see the 'hiddenfield'character rather than the data in the field. All other users see the data.


Hidden fields can be accessed and viewed on a work surface, but the field contains the hiddenfield character, ‘?’. If the field is referenced in an expression, it will contain the following: blanks for character fields, ‘F’ for logical fields, 00/00/0000 for date fields and blank for memo fields.

The corresponding SQL privileges are:

Operation

Description

SELECT

Users specified in the ACS may name the column in a SELECT statement. All other users have update access.

UPDATE

Users specified in the ACS may name the column in an UPDATE statement. All other users are restricted to read-only access.

READONLY

Users specified in the ACS may read the column in a SELECT statement. All other users have update access.


// Grant update privilege for columns lastname and firstname from the customer table
exec sql
  OPEN DATABASE southwind;
exec sql
  GRANT UPDATE (lastname, firstname)
  customers TO '[20,100]';

Encryption

From Recital 8.5 onwards, Recital installations that have the additional DES3 license option have the ability to encrypt the data held in Recital database tables. Once a database table has been encrypted, the data cannot be accessed unless the correct three-part encryption key is specified, providing additional security for sensitive data.

ENCRYPT

The ENCRYPT Recital 4GL command is used to encrypt the data in the specified table or tables matching a skeleton. If the skeleton syntax is used, then all matching tables will be given the same encryption key. The encryption key is a three part comma-separated key and may optionally be enclosed in angled brackets. Each part of the key can be a maximum of 8 characters. The key is DES3 encrypted and stored in a .dkf file with the same basename as the table. After encryption, the three parts of the key must be specified correctly before the table can be accessed.

// Encrypt individual tables
encrypt customers key "key_1,key_2,key_3"
encrypt employees key "<key_1,key_2,key_3>"

// Encrypt all .dbf files in the directory
encrypt *.dbf key "key_1,key_2,key_3"
SET ENCRYPTION

If a database table is encrypted, the correct three-part encryption key must be specified before the table's data or structure can be accessed. The SET ENCRYPTION TO set command can be used to specify a default encryption key to be used whenever an encrypted table is accessed without the key being specified. The encryption key is a three part comma-separated key.

If the command to access the table includes the key, either by appending it to the table filename specification or using an explicit clause, this will take precedence over the key defined by SET ENCRYPTION TO.

Issuing SET ENCRYPTION TO without a key causes any previous setting to be cleared. The key must then be specified for each individual encrypted table.

The default key defined by SET ENCRYPTION is only active when SET ENCRYPTION is ON. SET ENCRYPTION OFF can be used to temporarily disable the default key. The SET ENCRYPTION ON | OFF setting does not change the default key itself. SET ENCRYPTION is ON by default.

// Encrypt individual tables
encrypt customers key "key_1,key_2,key_3"
encrypt shippers key "key_2,key_3,key_4"
// Specify a default encryption key
set encryption to "key_1,key_2,key_3"
// Open customers table using the default encryption key
use customers
// Specify shippers table's encryption key
use shippers<key_2,key_3,key_4>
// Disable the default encryption key
set encryption to
// Specify the individual encryption keys
use customers encryption "key_1,key_2,key_3"
use shippers<key_2,key_3,key_4>
DECRYPT

The DECRYPT command is used to decrypt the data in the specified table or tables matching a skeleton. The specified key must contain the three part comma-separated key used to previously encrypt the table and may optionally be enclosed in angled brackets. The skeleton syntax can only be used if all tables matching the skeletonhave the same key.

The DECRYPT command decrypts the data and removes the table’s .dkf file. After decryption, the key need no longer be specified to gain access to the table.

// Decrypt individual tables
decrypt customers key "key_1,key_2,key_3"
decrypt employees key "<key_1,key_2,key_3>"

// Decrypt all .dbf files in the directory
decrypt *.dbf key "key_1,key_2,key_3"

All of the following commands are affected when a table is encrypted:

  • APPEND FROM
  • COPY FILE
  • COPY STRUCTURE
  • COPY TO
  • DIR
  • USE
  • SQL INSERT
  • SQL SELECT
  • SQL UPDATE
APPEND FROM
Used to append records to the active table from another table.
// The key must be specified for an encrypted source table
use mycustomers append from customers encryption "key_1,key_2,key_3"; for country = "UK"
COPY FILE
Used to copy a file.
// The key file must also be copied for an encrypted source table
// as the target table will be encrypted
encrypt customers key "key_1,key_2,key_3" copy file customers.dbf to newcustomers.dbf copy file customers.dkf to newcustomers.dkf use newcustomers encryption "key_1,key_2,key_3"
COPY STRUCTURE
Used to copy a table's structure to a new table.
// The key file is automatically copied for an encrypted source table
// and the target table encrypted
encrypt customers key "key_1,key_2,key_3"
use customers encryption "key_1,key_2,key_3" copy structure to blankcust use blankcust encryption "key_1,key_2,key_3"
COPY TO
Used to copy a table.
// By default, the key file is automatically copied for an encrypted
// source table and the target table encrypted with the same key
encrypt customers key "key_1,key_2,key_3"
use customers encryption "key_1,key_2,key_3"
copy to newcustomers
use newcustomers encryption "key_1,key_2,key_3"

// You can also create a copy with a different key
encrypt customers key "key_1,key_2,key_3"
use customers encryption "key_1,key_2,key_3"
copy to newcustomers encrypt "newkey_1,newkey_2,newkey_3"
use newcustomers encryption "newkey_1,newkey_2,newkey_3"

// Or create a decrypted copy
encrypt customers key "key_1,key_2,key_3"
use customers encryption "key_1,key_2,key_3"
copy to newcustomers decrypt
use newcustomers

// You can also create an encrypted copy of a non-encrypted source table

Summary

Recital offers a range of ways to keep your data secure. These start with the Operating System read/write permissions, which can be further refined to the level of table I/O operations and then field access in the Dictionary based Security and Protection rules. The Dictionary also provides the means to protect the integrity of the data via data validation and to assist in correct data entry through the use of choicelists, help messages and picture clauses etc. A further role of the Dictionary is in the provision of Table Triggers, which can be used to enable a programmatic response to table operations to add in additional checks or audit trails. For the most sensitive data, DES3 encryption is the ultimate protection: encrypting the physical data on the disk and only permitting table access on the production of the three part encryption key.

SE Linux is a feature of the Linux kernel that provides mandatory access control. This policy based access control system grants far greater control over the resources on a machine than standard Linux access controls such as permissions.

Many modern Linux distributions are shipping with SELinux enabled by default, Fedora 14 and Rhel 6 both install with it enabled.

When you run Recital Web on a SELinux enabled machine and navigate to the default.rsp page you will see something similar to the screen shot below.

1
If you launch the SELinux troubleshooter you will see the following problem.

SELinux is blocking the apache server from accessing the Recital server running on port 8001.

2
To manage you SELinux policy you must have the policycoreutils package group installed. The policycoreutils contains the policy core utilities that are required for basic operation of a SELinux system.

If you wish to use a GUI tool, you must install the policycoreutils-gui package.

At the command prompt execute the following:

As root

$ yum install policycoreutils

$ semanage port -a -t http_port_t -p tcp 8001

$ service recital restart

$ service httpd restart 
 

We use the semanage command here to allow the http server access to port 8001. Once you have completed the steps detailed above you can go and navigate back to the default.rsp page in your borwser, where you will find the permission denied message is now replaced by the default.rsp page.

SELinux does a great job of restricting services and daemons so rather than simply disabling it, why not work with it!

When it comes to security, every little bit helps...

Usually, you do not need to setup an email server under Linux. Most GUI email clients support Gmail POP3 and IMAP configurations. But, how do you send mail via the standard /usr/bin/mail user agents in a shell script? Programs such as sendmail / postfix / exim can be configured as a gmail smarthost but they are largely overkill for this use. The ssmtp program is a neat utility that does just that for you via gmail.

If you have software packages which you wish to share with others or simply between your own personal machines, a neat and easy solution is to create your own YUM repository and provide your .repo file for download.

YUM is by far the easiest method of installing software on Red hat, Centos and Fedora. Not only does it mean you don't need to trawl the web looking for somewhere to download the packages, YUM does a great job of satisfying any package dependencies. As long as the required packages are available in the enabled repositories on your system, YUM will go out and get everything you need.

To create your own YUM repository, you will need to install the yum-utils and createrepo packages:

yum install yum-utils createrepo

yum-utils contains the tools you will need to manage your soon to be created repository, and createrepo is used to create the xml based rpm metadata you will require for your repository.

Once you have installed these required tools, create a directory in your chosen web server's document root e.g:

mkdir -p /var/www/html/repo/recital/updates

Copy the rpm's you wish to host into this newly created directory.

The next step is to create the xml based rpm metadata. To create this use the createrepo program we installed earlier.

At the shell type the following command:

createrepo -v -s md5 /var/www/html/repo/recital/updates


This will create the required metadata in the repodata directory of your /var/www/html/repo/recital/updates directory.

root@test repodata]# ls -l
rwotal 44
-rw-r--r-- 1 root root 28996 Jan 13 21:42 filelists.xml.gz
-rw-r--r-- 1 root root   284 Jan 13 21:42 other.xml.gz
-rw-r--r-- 1 root root  1082 Jan 13 21:42 primary.xml.gz
-rw-r--r-- 1 root root   951 Jan 13 21:42 repomd.xml

To do a final consistency check on your repository run the following command:

verifytree /var/www/html/repo/recital/updates

We now have a fully functioning YUM repository for our hosted rpm packages.
The next process is to create a .repo file in the client systems /etc/yum.repos.d directory.

Navigate to the /etc/yum.repos.d directory on your system as root.

Using your preferred text editor to create the .repo file. In this example I will call it recital.repo.
Now paste in the following lines:

[Recital]
name=Recital Update Server
baseurl=http://ftp.recitalsoftware.com/repo/recital/updates
enabled=1
gpgcheck=1

Once that is saved, at the shell prompt on the same machine (YUM client system).

$ yum repolist
