You can use the definitions provided in the textbook or search them from other sources. I have chosen the digital forensics competency area and the definition of each key terms as listed in the textbook are as follows: i.

Its evolution can be noticed because in the earlier days the concern was to gain access into a computer system but nowadays security had become a must in every computer industry. Both information and computers need and depend on security nowadays. 18- What was important about the Rand Report R-609?

Demand for digital forensic services has shown a tremendous growth over the past few years. Criminals use computers to facilitate their criminal intentions. Their activities, plans, or even information related to their crime may be stored in a computer. In a criminal proceeding, it is necessary to prove that the computer is associated with the accused. This is when an expert is needed to set his expertise in the area and provide an explanation to the court.
Possible attack vectors for worms include the internet, removable media, and emails. Detection will be achieved by deploying forensic analysis software and through the manual review of audit logs. File integrity checking software will also be implemented to review whether files in the breached systems have been corrupted. File integrity programs can detect changes during an incident and are useful for revealing corrupted files (Cichonski, Millar, Grance, & Scarfone, 2013). Worms can be detected via the monitoring of ‘trusted processes,' ‘untrusted processes,' byte patterns, IP address scanning, and through the use of guardian nodes.
According to the Math (2010), Prof. Hany Farid has lately drawn attention of researcher worldwide by reporting digital image forgery problem. He developed the techniques how to detect digital image forgery. They are various ways how to manipulated the image like affine transforms such as translation, scaling rotation and shearing. Compensation operation like color, brightness, contrast, adjustment, blurring, enhancements and suppression operation such as filtering, compression and noise addition. .
Forensic Technicians are responsible for many tasks, these include: • Keeping records and preparing reports detailing findings, investigative methods, and laboratory techniques. • Collect evidence from crime scenes. • Testify in court about investigative or analytical findings. • Use photographic or video equipment to document evidence or crime scenes. • Visit morgues, examine scenes of crimes, or contact other sources to obtain evidence or information to be used in investigations.
It uses x-rays to create a computer image of the colon, without involving any kind of invasive procedure. The large intestine must be empty of stool, just like for the other procedures, but this will help to make colon screening safer and much quicker. It does not require sedation, but also does not allow tissue samples to be taken during the procedure. Though the x-rays used are highly sensitive, this method is currently not as reliable as a colonoscopy, as it is possible for polyps to be missed. If a lesion is identified, then a colonoscopy will be required.
I have personally run into barcode scanning issues with barcodes being duplications, the barcode not registering in the system, new medications not having any barcode at all, having to remember to reset all devices associated with the barcode so they will not show up on the next patients medial record and scanners not connecting to the base and needing to be calibrated. With these and a few more it can make for a not so seamless process. However, even with all of these thing mentioned barcode scanning is still very easy to use, even for the least technology-savvy nurses. Barcode scanners are small, durable and even mobile. Benefits are reassuring and well needed, which contributes to the hospital staff willing and wanting to use the technology
CO4507 Digital Forensic Investigation Introduction Nowadays digital devices are everywhere in our life’s helping peoples in many sectors and providing possibilities to them. By pronounce the term “digital devices” the majority of the peoples thinking the computers, smart phones, tablets and the cloud applications.

Any kind of technology that processes information can be used in a criminal way vise versa can be used as digital evidence in the court. For example the new version of TVs can sign in the web store images etc.
