Locking up computers with encryption

Article Abstract:

The increased use of networks and personal computers has increased companies' exposure to unlawful and malicious entry into their computer system. Some entry does no permanent damage to systems, but others can destroy data. Destructive programs include: time bombs which are introduced to a system and destroy hard disk data at certain times; Trojan horse programs which appear to be operating normally but are actually destroying data; and worms and viruses which can replicate themselves. Most companies are protecting themselves with outdated password systems, but some are experimenting with new encryption systems. Abstract Computer Ltd has developed an encryption system featuring an transputer-based Dataloc Key which uses standard data encryption to code information on hard disk and verify logon identifications.

Suppliers fight back on Open Systems

Article Abstract:

The adoption of Open Systems, a computing standard that eliminates many of the compatibility problems of software since it makes such software transportable across machines, is costing suppliers of proprietary systems money. For one, the European Commission prefers that public sector procurement should comply with Open Systems specifications. Tight competition and low profits add to the suppliers' woes. All is not lost, however. These suppliers have sought to regain their market share by establishing strategic alliances. So far, such corporate agreements are working smoothly.
