Why are passwords and other good information security technologies Essay

Why are passwords and other good information security technologies compromised by the people who use them What can we do to improve their contribution to information security - Essay Example Password attacks can be implemented by means of numerous diverse techniques, involving Trojan horse programs, brute-force attacks, packet sniffers and IP spoofing. While IP spoofing and packet sniffers are able to produce user accounts and passwords, password harasses usually refer to frequent efforts to recognize an user account and password; these repeated cracks are called brute-force attacks (Johnson, 2007). By means of the term information security we recognize an intellect of possible risks implicated in the sensitivity of the information. With information technologies coming into the view the image broadens its limits. At this instant it turns out to be essential to recognize the nature of hazard involved and next there should be a well-formulated description of the term safety itself (Rantasaari et al, 2003). In broad sense, there are necessarily three sides of the term security. Primarily, it shows the accessibility of assets, though material or virtual, that is beneath possession of an entity or grouping. Secondly, there is a sense of privacy involved in this practice in view to these assets, in this case data, dealings and communication. Third and as a final point, there should be an awareness of truthfulness which allows the user or users to consider in the context of security (Goldwasser et al, 2007). Here I will explain how passwords and other good information security technologies compromised by the people who use them. The first factor that usually causes the security leak is the sharing of the password by the people with anyone for any purpose. Passwords should not be shared with anyone because it can be casuse of information and data theaft and there is danger of accessing another individual’s protected resources, accounts and personal records. Anothre reason is not changing the passwords periodically. If we do not

Computer Forensics in Biology - Research Paper Example Application A structured investigation is carried out to sort out what exactly happened to the computer, when it happened, how it happened, and who did it. This is exactly like solving a murder case and performing postmortem. The operator does not know that the evident information is transparently being created and stored by the computer’s operating system, which can only be extracted through computer forensics software tools and techniques. The crimes include misuse of computer systems, attack on computer systems, using a computer system to work against another system, failure of a computer system, and the like. Though, internet identity theft has made people uncertain about shopping and selling online, checking their bank statements online, visiting auction websites, or entering into business contracts or transactions; however, computer forensics has played its part in helping law enforcement agencies in gathering digital evidence and identifying stolen identities as well as the criminals involved. Computer forensics security solutions focus not only on recovery but also on prevention of security threats in order to provide security solutions that are quicker and cheaper than the conventional techniques. These solutions include intrusion detection system (IDS), internet security system, biometric security system, net privacy system, firewall set-ups, network disaster security system, identity theft prevention system, identity management security system, and so on (Vacca 146). Basic Scientific Principles Involved It is important for computer forensic investigators to follow a structured approach to solving computer and internet-based identity theft cases. Computer crime involving ID theft can be grouped as physical security breaches, personnel security breaches, communications and data security breaches, and operations security breaches. A detailed investigation of the case requires that every security breach is analyzed independently to get a more syst ematic approach towards case solving. The digital examination of ID theft cases requires great expertise at the investigator’s end. The evidence or data that is collected is the valuable asset and has to be dealt with sensitivity, as it will help in deciding the specifications of the crime. Digital data is so delicate that it can be altered with one mistaken tap on the keyboard or one inadvertent press of a key. The forensic investigator will have to use some offline techniques in addition to online techniques. Although offline techniques are not the responsibility of a forensic investigator, but of course, he can use them to help himself toward finding the evidential data. He will have to look for any counterfeit documents, fake checks and bogus bank statements in black and white, in addition to looking for digital evidence residing inside the fraudster’s computer system.
