Easy routes ought to be actualized to permit the clients to comprehend the structure of the system and the few alternatives present on it. Availability of the system at all times and the minimal downtime in occurrence of an event. Business Proposed Solution The solution that has been proposed comprises of three sub-systems as: Catalog Information Membership Systems Purchasing Information System The three locations that the business is expanded in to can have the access to the database from a centralized file server. The centralized file server will allow the ease of managing the data from one single point and will also be easier in the management of the same. Implementation Issues Data protection and information security are the prime issues that emerge. The first and the foremost issue that comes up in the case of threat to the security to the information is data breach. It occurs when the data is maliciously monitored or captured and is then used to perform a unethical or misleading activity. Next in the list is the data loss. There will be a lot many instances when the data would be sent over from a source to destination over the network. The data may be lost in between by unauthorized means. It is also possible if the resource at the destination end loses the key to decrypt the data. Another serious concern in the list is that related to the hacked interfaces and Application Programming Interfaces (APIs). These interfaces open the path for an intruder to enter in the system and gain unauthorized access to the same. Sharing of resources is a common practice in case of such scenarios. The shared access allows the increased possibility of attacks and may also result in unwanted sharing of information. Some of the other issues that m ay come up during the implementation could be account hijacking, denial of service, distributed denial of service and inadequate due diligence. There are also a number of malicious programs that are present which may attack the system and perform malicious activities. Programs such as viruses, worms, Trojan horses and logic bombs can have devastating effect on the system as far as data protection and information security are concerned. References 1keydata,.
