Gus Remar found his neural nanonics coming back on-line, and immediately started to record his full sensorium, datavising his flek recorder block to make a backup copy. It had been a long time since he d covered a story in the field. These days he was a senior studio editor at the city s Time Universe bureau, but the old skill was still there. He started to scan around. 

If you ve ever been zapped by a power dropout or a loose power plug and have seen the ominous reset message, you know how it feels. The cost is high—your time and your work. It s easy to say always make periodic backup copies as you type in or write programs. But when the ideas are flowing, it s also easy to forget or procrastinate. "NoZap" does more than remind you—it does the SAVE for you, periodically and automatically. 

Journaling is the writing of all before and after images of modifications of the database to a journal file as well as to the database file. The journal device should be a device other than that used to store the database in case of failure. Database Operator utilities (DBO) are provided to specify the after image journal device (DBO/ AFTER-JOURNAL), make backup copies of the database (DBO/BACKUP), restore the corrupted database with the backup (DBO/RESTORE), and reapply all changes since the last backup from the after-image journal to the backup database (DBO/RECOVER). 

When you have finished t) ing Campaign Manager, make sure to save it to tape or disk (maybe a couple of backup copies as well). Turn your computer off and then on, go to 64 mode, load the program, and type RUN.

COLLECT performs a validate, freeing up any improperly allocated sectors. COPY and CONCAT let you copy or combine disk files on the same disk or between drives on a dualdrive system (but not with separate drives addressed with different device numbers). BACKUP can also be used only with a dual drive to copy one disk to another. APPEND lets you add new data to an existing file. DOPEN and DCLOSE make file handling easier, and RECORD makes relative files a breeze. The reserved variables DS and DS let you examine the disk error channel. DCLEAR clears all open disk channels. 

An attacker who wants to access a network protected by NAC should obtain the certificate and corresponding cryptographic key from an authorized host to authenticate successfully. Typically, certificates are public but private keys should only be accessible by the authorized user. Usually private keys are stored encrypted and users need to type a passphrase each time it is used. Passphrases can be compromised while transmitting them over an insecure link or via malware developed to copy passphrases or log them when users enter them using the keyboard. Another problem is the theft of storage devices used for key backup. Also, shared computers and possibility to export certificates to other machines make the management of certificates and keys problematic.
