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:

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.

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. |
|
ONDELETE |
The specified procedure is called prior to a delete operation
on the table. If the procedure returns .F., then the DELETE
is canceled. |
|
ONINSERT |
The specified procedure is called prior to an insert operation
on the table. If the procedure returns .F., then the INSERT
is canceled. |
|
ONOPEN |
The specified procedure is called after an open operation
on the table. |
|
ONCLOSE |
The specified procedure is called prior to a close operation
on the table. |
|
ONROLLBACK |
The specified procedure is called when a user presses the
[ABANDON] key in a forms based operation. |
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. |

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

WHERE customerid='RECIT';
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.
In this article Barry Mavin, CEO and Chief Software Architect for Recital provides details on how the Recital Database Server can be used to provide a solution for Universal Data Integration.
Overview
The Recital Database Server handles universal cross-platform data access to a wide range of data sources. The database server natively handles full remote SQL data access to Recital, Visual FoxPro, FoxPro, FoxBASE, Clipper and older dBase data. Using Bridges, it handles full remote SQL data access to C-ISAM and OpenVMS RMS. Using gateway connections, it handles full remote SQL data access to Oracle, MySQL, PostgreSQL, SQL Server, server-side ODBC, server-side JDBC and server-side OLE DB data sources. With its ability to access data using server-side ODBC, JDBC and OLE DB drivers from clients on all supported operating systems (Windows, Linux, Unix, OpenVMS), the Recital Database Server is an ideal Data Integration Solution for applications of all sizes and complexity.
Universal Data Integration Solutions
There are several ways in which data may be accessed by the Database Server.
Table 1:
Client Universal Data Access solutions for accessing local or remote data.
| Client | Solution |
|---|---|
| Recital | Use remote gateway connections |
| Visual FoxPro | Use the Universal ODBC Driver |
| Java (all platforms) | Use the Universal JDBC Driver |
| .NET Framework | Use the Universal .NET Data Provider |
| Microsoft Office | Use the Universal ODBC Driver |
| Windows Mobile | Use the Universal Compact Framework .NET Data Provider |
| PHP on Linux | Use the Universal ODBC Driver for Linux |
| Mono on Linux | Use the Universal .NET Data Provider |
| Others | If the data source you want to access is not in the list above, then you can use a remote ODBC, JDBC or OLE DB gateway. You can find examples of connection strings for most ODBC and OLE DB data sources by clicking here. |

When stress testing our loadbalancer, i was unable to get more than 20 reliable ssh connections. The following error would be reported.
ssh_exchange_identification: Connection closed by remote host
The resolution for this is quite simple.
Edit the /etc/ssh/sshd_config file and increase the MaxStartups. On my server i set this to 200.
Edit /etc/sysctrl.conf and add the following line:
net.core.netdev_max_backlog = 3000
Then apply this change:
# sysctl -p
