This essay discusses that there are also problems of implementation as some encryption programs do not ensure that the plaintext data they acquire is destroyed once it has been encrypted. These are acquired when systems use temporary files to protect in instances of data loss when the system crashes and to increase the available memory. The measures taken leave plaintext exposed and accessible on the hard drive and can easily be manipulated. In other cases, the operating system in computers leaves keys on the hard drive in the form of passwords that are easily broken by the user interface. Schneier states that “there are times when systems use master keys and also one-time session keys, where one is strong and the other is weak, the system is then broken by using partial information of the different keys”. It is clear that Cryptography plays a very integral role not only in securing sensitive government information. Cryptology is an important advancement in technology. In a day and age where people are very keen on computer programs and able to hack into national security databases, it is now more important. Seeing that there is a weakness in the cryptologic systems, data analysts and cryptologists must ensure that they write programs that are foolproof. In the same way that no one wants a thief having their bank details, we also do not want terrorists having sensitive national security information. Technology serves peoples purposes and it must then be used in the best way possible.

In this rapidly changing digital world of advanced hackers, new prevention techniques are invented for maximum prevention along with minimizing risks. One cannot predict that the blowfish encryption algorithm will also be replaced by the new and more secure algorithm known as (Anonymous2007, 500-500) two fish that will also be replaced at some period of this information age.
Digital security comprises of tools that an individual or user uses in securing his or her identity, technology and assets in the mobile and online world. These tools might be in the form of biometrics, web services, anti-virus software and secure personal devices that people carry with them every day.
Data protection from eavesdropping and potential hackers has seen a rise to complex and fool proof systems to ensure intended recipients get quality data. Issues such as proof of ownership, data integrity, authenticity, and data interception have made protection of sensitive information being transmitted a prime are of concern to parties involved.
The author states that the two economies have adopted the information systems defense & security and the cloud computing strategies in a bid to strengthen cyber security of critical national infrastructures, to secure information and technology systems in their respective countries, strengthen the administration.
Information and Computer Technology has facilitated countless aspects of the business process and has automated numerous work tasks. Its adoption by organisations and its subsequent integration into the business process have proven invaluable. At the same time, however, it has led to countless security issues and, as a rule of thumb, has imposed the imperatives of adopting cryptographic techniques and technologies by organisations who engage in any form of online commerce or which have an online presence.
This fast-moving medium has a tendency to move more quickly than the policies put in place to control it, but at the same time it links countries throughout the world, which is a benefit to a country like Canada, which, with the exception of its proximity to the United States, is somewhat isolated from the rest of the world.
