Throughout this course many software packages have been discussed as far as their usefulness and application in a computer forensics environment. I have chosen to write about encryption, as well as anti-spyware software. Specifically I will discuss TrueCrypt and Spybot – Search and Destroy.

TrueCrypt is a freely available disk encryption package. It is also open-source, which allows independent developers to legally change/modify and/or expand upon the software at their discretion, so long as all applicable terms and conditions of the TrueCrypt license are met. TrueCrypt also happens to be multi-platform, so it is not operating-system dependent. It supports Windows, Mac OS X, as well as Linux distributions. TrueCrypt volumes are also platform independent and can be mounted on different operating-systems.

There are several different methods of utilizing TrueCrypt to provide encryption for sensitive files, as well as to provide a layer of privacy. TrueCrypt can be used to encrypt entire hard drives, flash drives, as well as partitions. It can be used to force pre-boot authentication, by encrypting the drive or partition that an operating-system is installed on. The end-user of TrueCrypt can also provide fake boot error messages during the pre-boot authentication phase when the encryption password is incorrectly input.

TrueCrypt also has a semi-portable mode, in which TrueCrypt does not have to be installed in order to be executed. However, this requires administrative privileges in Windows due to driver requirements and has the potential to leave behind tracks in Windows registry. If this is a problem, TrueCrypt also allows the end-user to create hidden operating systems and hidden volumes. These offer the end-user ...

...nd Destroy and TrueCrypt are very effective software packages that are both provided free of charge. Both packages are well designed and perform their assigned tasks very well. However, like all software packages, none are without bugs and quirks, and they cannot be expected to perform properly in all environments. Thus, precautions should always be made before installation of any software packages on any system with the understanding that the end-user is the only one held liable for problems that occur due to software packages performing unexpectedly in ways that may cause damage to the end-users machines.

Forensic Science And Forensics Science Essays

- Both computer forensic or forensic science and Biometrics sometimes may apply same identification methods; however, they do so for different purposes. Computer forensics or forensics science is based on history and a forensic investigator does not just pick a method in advance. In other words, forensics investigators are unaware of what they will find as evidence. In addition, the manner in which forensics tools and evidence are handled may have critical implications, which can make or break a case....   [tags: Forensic science, Computer forensics]

Computer Forensic Lab Requirements : Computer Forensics Essay

- Computer Forensic Lab Requirements When initially embarking upon the task of defining computer forensic lab requirements, it may seem that the primary focus would reside within the technological portion of the lab simply because the nature of computer forensics is highly technical and complex. However, in reality, it is the structure (physical lab requirements) and the lab policies and processes (many of which are dictated by legal requirements) that actually make a computer forensic lab what it is, rather than simply a building full of high technology equipment and software....   [tags: Computer forensics, Forensic science]

Forensic Evidence Of Forensic Science Essay

- Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence....   [tags: Forensic science, Fingerprint, CSI effect]

Forensic Linguistics Assignment Essay

- Speech analysis has a type called the voice stress analysis that detects stress in the form of micro tremors in the speech of a person. It is important to note that the voice stress analysis is equivalent to polygraph. Both polygraph and stress have a common problem of not being able to point out deception. This notwithstanding, the speech analysis is apparently being used by both the Federal Bureau of Investigations and the Central Intelligence Agency of the United States. The fact that each and every person possesses a unique voiceprint makes the identification of a speaker to be theoretically possible....   [tags: Forensic Science ]
