Can Cryptography Prevent Computer Viruses?

As what I have learned or understood, a virus is any kind of file that has an ultimate goal, this goal is to infect all types of file that are being read by a virus or computer virus. Knowing this type of goal of the viruses, several experts have of course studied and occasionally proposed also solutions in order to prevent this kind of treats that people in this world are encountering with the so called disturbing computer viruses especially that really affects the state of the computer system. In line with this aspect, they proposed and develop a kind of technique that will sort of prevent the computer viruses from continuing this kind of job, and them what we call it as “cryptography”. This cryptography technique requires or provides an encryption key and a decryption key. The encryption key is used in order that a sample file will change its original contents, and decrypt that do will do the vise versa, so that there are so called the security especially to the files, and of course to the systems that will really help the computers against computer viruses and to some related bad threats. Since a system can only be infected if so computer viruses tend to read all the files that he can be capable of accessing through it. So without knowing the encrypted key or the decrypted key, either, this will cause to virus to those files to not work, isn’t it? And with the reason for that either a virus analyst must have a very well or shall I say have a perfect cryptographic algorithm that will also fight against computer viruses, perhaps it must have also a “perfect design, architecture, coding and user interface “as said by Bruce Schneier. With all of that these facts, these will really require great study or analysis to be developed by several virus analysts in order that these kind of encryption algorithm will perfectly be great help for providing the security against accesses of computer viruses as well as threats. And therefore I concluded that cryptography plays a significant task in computer industry especially with regards to secured in togetherness against viruses and against general emerging up-and-coming threats.

Is Java still secure?

As we all know we have several encounters with regards to various threats and Trojan horses, isn’t it? and this is a problem which really affects the security aspects of the new Java features. So by these they have studied and researched the features of the Java specifically with the components of this Java platform, and by these reasons there are some problems especially to entrusted applets that may be possible to be loaded to Java script browsers. However, they have studied in order to create a hypothesis by this topic, and asking if Java still secure?…..In line with this question, their very concrete answer also to that question was definitely yes, since according to them especially for unsigned or entrusted applets, the Java security manager still enforces the same sandbox, this sandbox is responsible for controlling those entrusted applets to be loaded. And according to Mr. John Q. Badguy “there must also requirements before those treats to be loaded to the browsers”, and I have guessed this kind of requirements requires a very concrete needs especially as permissions, so that it must have the key applets in the intranet, and of course in order to have security configuration of those Java engines and will not really have various prospect to do it wrong in that Java engine as well as in the Web browsers, right? And so as a whole, this Java still provides a powerful and of course still secure active content against those entrusted treats.

The Future of Viruses on the Internet

This very present time, computer viruses are steady low-level frustrations. Every company knows that it must have anti-virus software, and that virus protection is an asking price of doing businesses, that is the very reason in order to prevent those viruses. This involvement of viruses has only one reason and that is in order to spread those infections in the systems that may wipe out the functionality of the systems. But before this happen those viruses that came also from the internet, as what we have knew that in several organizations that do centralized incident management and reports has of course anti-virus software well deployed, most incidents involve only one or two systems, and the virus is caught before it can spread beyond. So those viruses are just being disinfected automatically with the use of that anti-virus software. And of course when some instances really occur like for example new viruses are discovered, anti-virus software is also being updated to deal with them, and again on a sequence of weeks or nevertheless in months, and that is according to them and of course of what I have noticed, that really happens all the time. So by this these viruses are just like business by now that when the problems occur automatically there are also updates in order to give solutions on them. The Internet only serves/plays a comparatively small role of spreading of those treats/viruses and of course gives also some detection and gives preventions in order that these viruses will not be spread throughout the systems.
