File security

The Import Wizard process for Microsoft Access files works like the one for Excel files and produces similar PROC IMPORT code. Keep in mind that text fields get a default length of 255 characters when PROC IMPORT is used with Microsoft Access files. PROC IMPORT adds a number of file security options, as well as the ability to scan memo fields via the SCANMEMO option to determine the width of character fields in Microsoft Access files. 

Passwords file security—Passwords file shall be protected or otherwise secured so that the password cannot be read by ordinary means. If the password file is not protected by strong access controls, the file can be downloaded. Password files are often protected with one-way encryption so that a plain-text password is not... 

File Security. While it may be that a specific class of user has access to the entire contents of a folder, it may just as well occur that members of that class have access to all documents in the folder with some exception. For example. Human Resources employees may have access to documents containing the terms of employment for all employees except those in Human Resources itself. Security must be applied to these particular documents in the EDMS such that they cannot be viewed by Human Resources personnel. 

Which Windows operating system would provide high performance and file security ... 

NTFS The NT File System was created to provide enhanced security and performance for the Windows NT operating system, and it has been adopted and improved upon by Windows 2000. NTFS provides Windows 2000 with local file security, file auditing, compression, and encryption options. It is not compatible with Windows 9x or DOS. 

If the format of your report of a workplace survey or inspection remains your choice, it should be well considered, under headings such as those suggested by this chapter. The report should end with a concise summary of findings, clear recommendations for actions to be taken or further investigations, and any proposals for follow-up. The confidentiality of information about individual cases mentioned in the report should be respected at all times. Dispatch of the report may need to be followed by a further meeting between you and interested parties. Your copy should be filed securely but retrievably. 

The apparatus consists of a tube T (Fig. 76) usually of total height about 75 cm. the upper portion of the tube has an internal diameter of about I cm., whilst the lower portion is blown out as shown into a bulb of about 100 ml. capacity. Near the top of T is the delivery-tube D of coarse-bored capillary, bent as shown. The tube T is suspended in an outer glass jacket J which contains the heating liquid this jacket is fitted around T by a split cork F which has a vertical groove cut or filed m the side to allow the subsequent expansion of the air in J. The open end of the side-arm D can be placed in a trough W containing water, end a tube C, calibrated in ml. from the top downwards, can be secured ts shown over the open end of D. 

This requirement supplements that for records to be readily retrievable but in addition implies a further requirement for security of records. After addressing the filing and storage requirements, you need to ensure that the records are accessible to those who will need to use them. This applies not only to current records but to those in the archive and any insurance copies you may have stored away. A balance has to be attained... 

The filing provisions you have made should enable your records to be readily retrievable however, you need to maintain your files if the stored information is to be of any use. In practice, records will collect at the place they are created and unless promptly removed to secure files may be mislaid, lost, or inadvertently destroyed. Once complete, quality records should not be changed. If they are subsequently found to be inaccurate, new records should be created. Alterations to records should be prohibited as they bring into doubt the validity of any certification or authentication as no one will know whether the alteration was made before or after the records were authenticated. In the event that alterations are unavoidable due to time or economic reasons, errors should be struck through in order that the original wording can still be read, and the new data added and endorsed by the certifying authority. 

The sponsor and investigator, as appropriate, must retain all essential documents relating to the trial for at least 5 years after its completion. Documents should be securely archived, with restricted access to maintain subject confidentiality. Collectively, these constitute the Trial Master File, and facilitate any audit and evaluation of... 

E-mail as a communication tool has a number of drawbacks. First, it is vulnerable to being intercepted. This is a major security problem, especially when sensitive files are attached. Second, intended recipients may not access their e-mail on a timely basis, thus delaying any action that might need to be taken. Third, there is the possibility of sending files inadvertently to the wrong recipient. 

File transfer protocol (FTP) technology is a data communication tool that allows sending, accessing, and sharing files quickly and easily through a secure environment. The user logs onto the FTP site with a valid account name and a valid password. This method allows participants to share data files instantly. 

Archiving - placing files received and transmission logs into secure, long-term storage. 

Once you have your SAS data ready for transport, you need to determine a means to deliver it. There are many ways to send data, but you should strive for process simplicity and data security. To keep your data secure and to comply with 21 CFR-Part 11, you need to encrypt your data files for transport. The best encryption you can use is key exchange high-bit encryption software such as PGP, which creates essentially unbreakable files when used properly. Once your data files are encrypted, you can either send them on physical media such as CD-ROM or send them electronically with secure transmission software such as Secure File Transport Protocol (SFTP). If you need to send data to someone once, a CD-ROM is simple enough to produce. However, if you need to send the data repeatedly, then you should use a more automated electronic method of data exchange. Shell scripts and batch files can be written to automate the electronic data transfer process. 

File Transfer Protocol. A protocol used to move files over the Internet. Typically, you use a command line command, browser capability, or program on your computer called an FTP client to connect to an FTP server found on the Internet. Once connected to the FTP server, you can move files back and forth between your computer and the FTP server. SFTP, Secure FTP, is a more secure protocol for moving data over the Internet in which both your login information and data are encrypted during communications. 

The file clearly demonstrated extensive knowledge of Phillip s background with the Department of Defense and his security clearance. While it was made obvious that the Chinese knew all about him, blackmail was the furthest thing from their mind. Their main concern was Alex Houston. The Chinese knew Houston had been involved with the CIA, drugs, money laundering, child prostitution and slavery. The comment from this Chinese bearer of bad tidings was, " Houston was a very bad man and his crimes were of the White House." (24)... 

For example, C++ works with an OO model in main memory but leaves persistent data up to you you can t send a message to an object in filestore. If you can secure a good OO database you re in luck but otherwise, typically you re stuck with plain old files or a relational database and must to think how to encode the objects. Your class-layer design should initially defer the question of how objects are distributed between hosts and media.
