    On 5 October 2009, computer equipment from a network data closet was stolen from BCBST. The items stolen were 57 unencrypted hard drives which contained over 300,000 video recording and over one million audio recordings. According to Whitman & Mattord (2010), confidentiality, integrity, and availability makes up the C.I.A triangle which is the basis of Committee on National Security model for information security, an industrial standard, (Whitman & Mattord, 2010). Confidentiality can be a synonym for encryption but also means only the people with the correct permission can access the information. One of the major security issue is the hard drives were not encrypted. The hard drives should be encrypted to prevent people from reading the information the computer. Software can be purchased which will encrypt files on hard drive with such as Folder Lock, SensiGuard, Secure IT, and more. There are open source encrypting software which are free for use which could have been used. If the hard drives were not needed, the data should hav...

A scientific method example would be when an investigator arrives to a crime scene, they would first search the area for clues and see if something doesn’t seem right. Next they would have to search for different forms of evidence, most important would be trace evidence because it can provide DNA evidence which can also link a suspect to the crime. There are many more ways evidence and other clues can be harvested from a crime scene but it is up to the investigator to use their knowledge and help find the person responsible for the crime

    The biggest challenge investigators face and who is involved with high tech crime is the fast-paced constant evolving nature of technology. When companies come out with new devices or new versions of old devices which is almost all the time, and those who gather digital evidence must remain current to be able to locate and preserve all potential evidence. As technology evolves the capacities of these devices will rapidly increase while their form factor grows continually smaller. Investigators must preserve digital evidence to make sure it is suitable for presentation in court as well. Investigators must first never change a crime scene or alter evidence. It is their goal to document and preserve the scene exactly as it was when the crime occurred. Extreme caution and care is needed because the mere act of documenting or cataloging a crime scene means that investigators are interacting with the scene. The second concern is the physical fragility of the evidence. Care must be taken to keep items from getting wet, stepped on etc, this can also be applied to digital evidence. Investigators have been able to examine hard disk drives that have been through fires because the drives are usually air and water tight and impervious to temperatures into the thousands of degrees. The third issue is that digital evidence can be lo...
