Paper Abstract: Analyzes the use of mobile code, including security considerations on networks, and concludes that mobile codes are necessary and useful, but require strict security measures to maintain data integrity. Paper Introduction: Mobile Code Introduction Even casual computer users are familiar with firewalls programsdesigned to protect their computers from malicious programs that mightdownload themselves onto unsuspecting machines when they are connected tothe Internet What many computer users may not understand is that the sametype of programs that might contain viruses and Trojan horses are also usedto perform critical functions when one is connected to the Internet Thesesmall programs automatically download themselves onto machines withoutaction from the user and run in the background Typically users Text of the Paper: The entire text of the paper is shown below.

Web surfing is more pleasant and more efficient becauseof mobile code, and in most cases, mobile code does not cause damage tonetworks. Mobile Code Introduction Even casual computer users are familiar with firewalls, programsdesigned to protect their computers from malicious programs that mightdownload themselves onto unsuspecting machines when they are connected tothe Internet. Mobile Code: Friend or Foe? Initially,information technology security professionals may be tempted to simplydisallow any mobile code to be installed on workstations connected to theInternet. For mostusers at most times, mobile code enhances the Web experience making itpossible to enjoy more varied Web sites that offer a richer experience in amore timely manner than if mobile code was not in use. Typically, users areunaware that any download has taken place. With thewidespread use of mobile computing devices such as personal digitalassistants (PDAs) and even cell phones that can run mobile code, this typeof code has come under increased scrutiny (Barman 1). From this standpoint, mobile code can be both a helpand a hindrance to the information technology community (Grimes 16). Mobile code is also used torun Java applets that enhance the Web experience for users. What many computer users may not understand is that the sametype of programs that might contain viruses and Trojan horses are also usedto perform critical functions when one is connected to the Internet. When these programs are usedfor legitimate purposes, they enhance processing speed and enable users toperform functions that would be more difficult otherwise.

Security Considerations The security implications of mobile code, as indicated from the typesof malicious mobile code, are significant and far-reaching. Conclusion Mobile code provides too many benefits to be eliminated altogetherfrom the Internet. While this can be an effective defense against malicious mobilecode, it is overreaching the actual problem in most cases. Types of Mobile Code Legitimate examples of mobile code include data validation on forms,basic processing, and customized Web pages. Thesesmall programs automatically download themselves onto machines withoutaction from the user and run in the background. This research considers the useof these types of programs, their security implications, and whether theyare actually friends or foes to information technology securityprofessionals. The Java Virtual Machine (JVM) provided an ideal environment formobile code, and its use proliferated at the same time that analystspredicted that its use would revolutionize the online experience. However, information technology professionals need to recognizethat networks are vulnerable to attacks by malicious mobile code, and needto take steps to prevent or mitigate attacks. As with many other computer applications, it is impossible to saywhether mobile code is friend or foe to computing professionals. However,mobile code has gained increased publicity when it is used for maliciousattacks. However, there areprogrammers who delight in creating malicious code that downloads itself inorder to destroy data, interrupt service to particular Web sites, or engagein illegal activity. "Writing Mobile Code Policies." QuePublishing.com. Works CitedBarman, Scott. Instead,information technology security professionals should focus on isolating thetypes of mobile code that poses significant threats to their system andtake actions that prevent those codes from being executed ("Websense"n.p.). The code is downloaded from the remote server ontothe workstation, and executes such that the user is unaware of theactivity. Mobile code was originallydesigned so that programmers could write routines to perform datavalidation, basic processing or similar tasks without requiring additionalinput from the user. However, someprogrammers use these programs for malicious purposes, and so securitymeasures are necessary to protect systems. Such activities requirerecognizing the risk that mobile code poses, and protections designed toprotect against those risks. "Malicious Mobile Code." Software World 34(Jan 2 3): 16.Piscitello, David. Retrieved from the Internet 9 Apr 2 4: http://www.quepublishing.com/articles/article.asp?p=26229&seqNum=1.Grimes, Roger. These attacks may include viruses that disable a computeraltogether, Trojan horses--programs that are run at a later time to destroydata, modification of the security settings in order to open an opportunityfor hackers to gain access at a later time, or sending sensitiveinformation to a remote Web site (Piscitello 42). Definition Mobile code is small programs that are downloaded onto computerswithout the user's knowledge or action.
