On the destination computer, the data is restored to its original form so it can be read and understood by the recipient. Hypothesis The data is encoded so if there are those who tap data In this phase the officers will make hypothesis based on the transmission, the party cannot understand the content of the facts that has been acquired and examined.

The hypothesis will data that is sent as it is still encrypted. There are two processes that occur in In this step, the officers make hypothesis based on the evidence cryptography, the encryption and decryption process. The they collected. This hypothesis should be done so the encryption process is the process of converting the original data prosecutors can get the whole picture of the case. Original data is Presentation called plain text, while the encrypted data is called cipher text.

The officers will presents the hypothesis and check them The encryption process occurs in the sender's computer before again with the facts and if the possibility is high then continue the data is transmitted, while the decryption process occurs on to the next step. On this phase, the officers should present the the recipient's computer as soon as the data is received. The hypothesis about suspect to the victims. Therefore, the browser is equipped with Secure Socket just kids so they feel sorry about their sentences.

This event Layer which serves to encode the data. In this way, the might not happen if the victims know about the hypothesis of computers that are in between the sender and the recipient suspects from the officers. This presentation phase is important computer can no longer read the contents of the data.

On this phase, Unfortunately, until now many countries do not have specific there is two choices, whether to take the case into the next level law concerning information technology yet. Specialized which is taking the suspects into trial or drop the case if the institutions, both public and NGO Non Government case is not worth it. The decision phase will also discuss the Organizations , are required for the reduction of crime on the policy about the information stored, whether keeping it until internet.

Computer Emergency Team Response.

If there is a standard method in conducting the increasingly growing in line with advances in technology, the investigation, the work will be more efficient. Therefore, the police should take some improvement in many aspects, such standardization of computer forensics model is necessary to as: personnel, infrastructure, cooperation, coordination, forensics analysis in Indonesia.

Some important steps that must be conducted by every state The effect of cyber crime can be reduced by securing the concerning the cybercrime are formulating cyber laws, system. The goal of a security system is to prevent the enhancing national computer network security system destruction of parts of the system as entered by unwanted users.

System security measures should prevention, investigation and prosecution of case related to be integrated in the overall system, with the aim to prevent cybercrime, encouraging citizen awareness about the problem unauthorized access.

Personal security can be done starting of cybercrime and the importance of preventing these crimes from the installation of the system until finally heading to the occurred, increasing cooperation between countries, both stage of the physical security and data security. Securing the bilateral, regional and multilateral, in dealing with cybercrime. Internet firewall serves to parent, family, spouse, colleagues for any kind of support, prevent access from the outside to the internal system.

Thus the Ministry of Energy and Mineral Resources of The Republic of data are in the computer network cannot be accessed by outside Indonesia for financial support, Dr. Suhardi from Bandung parties who are not responsible. Firewall works in two ways: Institute of Technology for material support, and any parties, using filters and proxies. The firewall filters communications friends, colleagues who give many support to the writer. Retrieved from [1] United Nations.

It was also suspected that the August plot to down assorted transatlantic flights from Heathrow involved the mixing of TATP onboard. It continues to be popular among both youngsters, for its simplicity, and extremists, for its devastative effects.

A simple Google search reveals dozens of sites with step-by-step instructions for the compounds preparation, including several how-to videos on popular social networking sites. Disadvantages to the Internet include an increasing dependence on cyber information. Many undergraduate students rely exclusively on knowledge gleaned from electronic sources. Unfortunately, the quality of information found in cyberspace is often questionable, and displacement of humanity has resulted from this dependence on artificial intelligence.

More importantly, new technologies have a history of breeding new forms of socially undesirable behavior, while enhancing traditional ones. Just as the automation of the printing press and the introduction of mass media exponentially increased the distribution of and demand for criminal contraband, like pornography and illegal substances, the Internet has established a virtual cornucopia of child exploitation and obscenity and has created an underworld marketplace for drugs and weapons.

In fact, the level and prevalence of criminal behavior and exchange of visual or informational contraband have never been this high. The increasing availability of w ireless technologies, social networking, and smart phones has complicated the investigative landscape even further, and authorities across the globe are struggling to create and enforce laws and regulations inclusive of emergent technology.

Cyberspace and Criminal Behavior Cyberspace may be defined as the indefinite place where individuals transact and communicate. It is the place between places. In fact, traditional electronic communications have always fallen within this existential space.

Telephonic conversations, occurring across time and space, were pre-dated by wire exchanges.

However, the new medium known as the Internet has monumentally increased the physicality of the virtual world, outpaced only by the exponential growth in the number of users. In , for example, approximately 78 percent of the United States actively used the medium Chapter 1 Introduction and Overview of Computer Forensics and Cybercrime as compared to 10 percent in In the UK, the growth was even more evident with users of the medium rising from 1. Unlike traditional methods, the Internet combines mail, telephone, and mass media.

As stated previously, it exposes individuals to a myriad of new ideas and may serve as a social gathering place, a library, or a place to be alone. As such, the existential nature of the medium does not negate the reality of its consequences. Individual users have married, planned their lives, and stalked our children there.


Unfortunately, this virtual world is often perceived as a painless alternative to worldly problems, where individuals shed their worries and become perfect in their profiles. Privacy advocates have often overlooked the negative repercussions of this global medium, arguing zealously that the potentiality of emerging technology precludes governmental interests in monitoring citizens.

Both Barlow and Gilmore have been most vocal in their defense of some of the most notorious computer hackers in the United States and have championed the Bill of Rights. They argue that the original thrust of the frontier police, directed at neer-do-wells intent on compromising the privacy of American citizens, has been refocused on the very individuals that they originally protected.

In fact, the two created the Electronic Frontier Foundation EFF offering to fund, conduct, and support legal efforts to demonstrate that the Secret Service has exercised prior restraint on publications, Case in Point Second Life: The Virtual World Realized As of this writing, there have been a variety of virtual communities that have appeared in the existential world of cyberspace.

Most have demonstrated the vacillating, and often ephemeral, nature of most virtual creations. However, Second Life SL , developed by Linden Lab in the dawn of the twenty-first century, has proven that Internet-based worlds appeal to a number of users.

Commonly referred to as SL, Second Life may be characterized as a social networking site on steroids.

Users, or residents, are represented as three-dimensional, animated agents or avators, who can engage in virtually every activity common to the physical human experience.

They can download property, shop for clothes, receive plastic surgery, engage in sexual relationships, marry, have children, and even visit deceased loved ones in the SIMetery. They may attend university classes, gamble in a casino, or teleport across the globe with a simple click of the mouse. In fact, the academic and business communities have taken note and developed a presence in this virtual world.

However, many individuals invest a considerable amount of time and money in this virtual existence without compensation,6 and an abeyance of norms and ideologies has been noted. Virtual communities not only span geographical borders, they transcend cultural boundaries as well.

Expectations regarding race, ethnicity, and national origin are displaced as artificial creation of the presented self i. In other words, residents recognize the incongruity between physical selves and virtual representations, and embrace the artificiality which disposes of physical, social, and economic factors which may trouble them in the real world.

Thus, aberrant behavior demonstrated in these worlds is only constrained within the virtual, and not the physical, world; and, yet the consequences of such are not necessarily so.

As an increasing number of users blur the boundaries between their first and Second Life, questions regarding the legality of avatar-simulated behavior emerge. If the avatar owned by an American adult male engages in sexual behavior with an avatar owned by a year-old child from Thailand, what crime, if any, has occurred?

In a chat room conversation between a pedophile and a child, the law still requires that an affirmative act toward the commission of physical exploitation or molestation occur.

Appearance at a prearranged meeting place satisfies this requirement. In a world where reality is grounded in assumptions of misrepresentation, can the legal requirement of mens rea or criminal intent ever be satisfied? Chapter 1 Introduction and Overview of Computer Forensics and Cybercrime limited free speech, conducted improper seizure of equipment and data, used undue force, and generally conducted itself in a fashion which is arbitrary, oppressive and unconstitutional. Secret Service may validate some of these early concerns, the efforts of the EFF have often overlooked the negative potentiality of this global marketplace that has reunited a society that had increasingly removed itself through suburbanization.

Beginning with the Industrial Revolution, American society has long been characterized by its distrust of strangers. As media attention increasingly focused on elevated levels of predatory crime perpetrated by nonacquaintances during the s, this fear resulted in a myriad of proactive attempts by both government and citizens to reduce their perceived vulnerability. Among these were admonitions to children to avoid strangers and lock their doors.

While such precautionary measures may have been well served in regards to physical crime, the advent of technology has lowered traditional barriers and served as an informal invitation for unknown visitors.

Many such as the victims of theft, stolen privacy, and the likehave recognized only too late the dangers of their inattentiveness, while others, yet to suffer negative consequences, remain blissfully unaware of their own vulnerability.

In fact, most individuals, young and old alike, are seduced by the soft hum of a device that appears to be the gateway to worlds that were previously restricted. Unfortunately, this fascination may be exploited by those we try most to avoidcriminals and predators.

Digital Forensics and Cyber Crime

As stated previously, technological advancements have historically led to criminal innovations. Indeed, this latest technological era has exacerbated the vulnerabilities of government institutions and personal residences alike.

Critical infrastructures, increasingly characterized by tight couplings and interdependency of IT, emergency services, public u tilities, banking sectors, food supplies, and transportation systems, have resulted in an interconnectivity inconsistent with traditional security strategies.

Such myopia has similarly impacted private citizens who have failed to employ rudimentary m easures of cyberprotection even as they add additional doorlocks and alarm systems to insulate themselves from physical attacks. In fact, it may be argued that the Digital or Information Revolution has created a criminogenic environment in which traditional criminals adapt and new criminals emerge.

Clarification of Terms Just as debates rage over the appropriate codification of crime committed via electronic means, controversy surrounds the actual semantics associated with the phenomenon. For clarification purposes, then, it is necessary to define the historical usage of terms associated with technological or electronic crimes.

Computer crime has been traditionally defined as any criminal act committed via computer. Computer-related crime has been defined as any criminal act in which a computer is involved, even peripherally. Finally, d igital crime, a relatively new term, includes any criminal activity which involves the unauthorized access, dissemination, manipulation, destruction, or corruption of electronically stored data.

As data may be accessed or stored in a variety of ways and in a variety of locations, digital crime may be characterized as any of the three depending on case c haracteristics.

While computer crime and computerrelated crime will be used interchangeably throughout the text, cybercrime will only Chapter 1 Introduction and Overview of Computer Forensics and Cybercrime Techno-Lingo Computer Crime, Computer-Related Crime, Digital Crime, and Cybercrime Computer crimea general term that has been used to denote any criminal act which has been facilitated by computer use.

Such generalization has included both Internet and non-Internet activity. Examples include theft of components, counterfeiting, digital piracy or copyright infringement, hacking, and child pornography.

Computer-related crimea broad term used to encompass those criminal activities in which a computer was peripherally involved. Examples include traditional bookmaking and theft. Digital crimea term used to refer to any criminal activity which involves the unauthorized access, dissemination, manipulation, destruction, or corruption of electronically stored data.

Cybercrimea specific term used to refer to any criminal activity which has been committed through or facilitated by the Internet. Additionally, students should be advised that a variety of definitions exist, and that such variations have resulted in confusion among legislators and investigators alike. Some authors, for example, argue that any crime that involves digital evidence may be characterized as a computer crime.

This is misleading at best and self-serving at worst.While some countries rate computer crime as a high priority, for example, others have embraced computer criminals, protecting them from international prosecution. Digital Forensics and Incidence Response. Are you sure you want to Yes No.

Considering the astonishing pace at which new information technology — and new ways of exploiting information technology — is brought on line, researchers and practitioners regularly face new technical challenges, forcing them to continuously upgrade their investigatory skills.

These models can be used by computer forensics investigators in The officers then get authorization to search for evidences.

As an increasing number of users blur the boundaries between their first and Second Life, questions regarding the legality of avatar-simulated behavior emerge. It is information and communication technology has also led reported by [15] that the court assembly received novum new borderless relationship and causing changes in social, evidence that the case could not classified as defamation case. As stated previously, technological advancements have historically led to criminal innovations.
