Computer Forensics Report—What You Ought to Know

Tuesday, August 19th, 2008

What consists the computer forensics reports? Where are they based from? More so, with the people’s continued reliance on the Internet, the computer forensics investigators are tasked to unearth all information which have been made using the emails, file transfers, Internet website searches, online account negotiations, chats and any other transaction made over the Internet.

Computer forensics reports are prepared by none other than the computer forensics investigators who gather the necessary information, analyze them and then draft out the final computer forensics reports. In the advent of the multifarious computer-related crime incidents, the criminals oftentimes leave behind the clues which aid the investigators to track down the root cause of the crime.

Even when the files have been deleted from the specific location in the computer, the original data is not at all erased from the entire computer system. With the certain techniques, tools, and skills that the investigators are equipped with, the analysis of the fraudulent act or crime can be made much accurate.

As soon as the evidence has been derived from the electronic media, the computer forensics experts prepare their computer forensics reports. The lawyers who are in charged to tackle the cases are prompted to gather as much bundles of information as possible as it is needed in the course of the computer forensics dealings.

Among the significant cautions to note of include the backing up of the compressed data, tapes, encrypted data as sourced out from the computer system’s platform, and the collection of the password protected files.

There is only one problem that computer forensics reports get affected with though, and that has something to do with the strides in the modern technology that nonetheless make the achievement of the reports pretty hard. If the software or tool that the investigators use is not updated, the more it is difficult for them to arrive at a precise conclusion and findings. Thus, there is the necessity of the continued update when it comes to the computer forensics tools and software applications.

Where are the computer forensics reports sourced out from? There are mainly four areas from where the investigators gather their evidences. Yes, there are other areas which are looked into but the following are the most commonly looked into.

The saved files. These are the bits of information which are viewable on the computer itself. The task of looking into these files is not at all complicated.

The deleted files. These data are either placed into the trash or those which require the special software in order to restore them.

The temporary files. These data are produced when one browses through the Internet, works on any document, and uses some other types of backup software and other installations and applications. All of these may only be uncovered through the use of a special tool or software.

The meta data. These are the details which are related with the information that have something to do with a document or file. Among the details which appear include the date that such files had been created, modified, and the last time when it was accessed. An add-on information is about the creator of the said file.

Indeed, computer forensics reports can only be made precise with the proper skill and technique which the person in charged will exert.

What Remains to be Today’s Computer Forensics Problem?

Tuesday, August 19th, 2008

Computer forensics is one the fields today which often gets updated. Many agencies have found the application of computer forensics very useful especially in the investigation of fraudulent actions and crimes. More so, computer forensics is the procedure that is applied when electronic devices such as the computer media is placed under careful investigation.

The process involves the discovery and analysis of any available data whether they have been hidden or deleted. These are among the evidences that will support the defense and claim of a particular individual or company as they file for any legal action.

Moreover, computer forensics specialists use the tools that recover both the accidentally and intentionally erased files and information. So whether the loss of the data is blamed to the untoward occurrences of hardware failure, there is a better chance of recuperating them. One of the biggest computer forensics problems though is how to retain the original data without the slightest alteration in them.

So much to say, even during the process of shutting down the computer system to transfer the data into another media may cause changes in them. It is important that the computer forensics expert has the skill to maintain the exact form of the data. Nobody can exactly say when the data may be altered but with the most apt tool and the specialist’s skills, it can be possibly prevented.

Computer forensics attracted the attention of the public during the height of the Enron scandal which prompted the widest-ranging computer forensics investigation marked in the world’s history. As computers these days are becoming an integral part of human life, big quantities of data are being stored in these electronic devices.

More so, crimes and other fraudulent acts are likewise increasing in intervals. Computer forensics investigations are also done in emails, websites visited, chat histories, and many other forms of electronic communications.

The advances in today’s technology have shaped the improvement of computer forensics. The developers continually upgrade their tools to meet the increasing intensities of computer forensics problems. Modern software and tools are coming out into the market which nonetheless makes the task easier for the computer forensics experts. Thus, data is found and restored faster and with more preciseness.

These evidences need to be in their original format especially when they are to be used as evidences in the court. These proofs are often gathered from all kinds of computer media such as the discs, Pen drives, tapes, memory sticks, logs, emails, PDAs, handhelds, deleted information, and hidden documents.

The people’s common notion is that when the data is deleted from its location, the file is already completely deleted and unfound. This makes you wrong though. Upon deletion, what is erased is only that of the data’s reference location but the actual document remains intact in your computer system.

It is easiest to tell that the data have been deleted but the common computer forensics problem is where and how to find it and how to recover them without making traces of changes. Thus, the solution to the dilemma will entirely depend on the computer forensics professional’s skills.

Computer data security is very important so it is also significant that they remain original. Part of the training of these professionals includes the molding of their skills to be careful when handling the recovery of the data at all times.

However, it is not for them to conclude when data may be altered or not. This remains as one of the top computer forensics problems to date.

What is Computer Forensics?

Tuesday, August 19th, 2008

Computers have radically changed the way we live your lives. Everyday living as become easier and technologically advanced decades ago. It has changed the way we work and the way we live in our houses. Children to day are sometimes even more technologically aware than their parents. Mobiles phones have gotten smaller and laptops have gotten slimmer.

With the launch of the Iphone that used the touch screen technology it will only be a matter of time when this idea permeates into other devices and appliances. Unfortunately, technology also makes it easier for criminals to their dirty job. However, computer forensics makes sure that technology is put to lawful use.

Everyone keeps up with the times, even the criminals. The internet is a public place which makes it vulnerable for fraud. Criminals often take advantage of unsuspecting victims. Law enforcement agencies have incorporated computer science in their investigation process to aid them with computer savvy criminals.

Crime and computers

We have seen a lot of Hollywood movies about hackers stealing from financial institutions. We have also seen two parties making their deals through bank transfers with a bunch of computers. Although these are not possible in real life, there are other ways that criminals can use computers.

Computer forensics is basically applying computer science to assist in the legal process. It entails the technological and systematic inspection of the contents of a computer system for evidence. Individuals in this field are called by different titles such as digital media analyst or computer forensics investigator. These people scanned a computer thoroughly to find out if they have used for a civil wrongdoing or criminal act.

The skills required are more than just normal data collection and using preservation techniques. Other definitions include the use of special tools to meet the Court’s criteria and not just a thorough examination of a computer for potential evidence. This definition is similar to Electric Evidentiary Recovery or e-discovery.

Most of the time computer forensic investigators investigate hard drives, portable data devices and data storage devices. These devices include USB Drives, Micro Drives and external Drives.

The first task of the computer forensic investigator is to find sources of documentary or digital evidence. The next step would be to preserve the evidence so that it could be analyzed later on. When dealing with computer systems, important files or data can be quickly lost.

The investigator should take the necessary test because data retrieval can be time consuming and costly. The investigator would then analyze the collected data for potential and supportive evidence. The final step would be presenting the findings. The investigator will render his opinion based on the examination and make a report.

The process of using computer forensics must comply with the standards of evidence that are acceptable in court. This field is both technical and legal. The investigator should also have a complete understanding of the suspect’s level of sophistication. If they don’t the suspects are assumed to be experts.

Investigators then presume that the criminal have installed a countermeasure to render forensic techniques useless. The computer will then be shutdown completely to prohibit the machine from making further modifications to its drives.

Computer technology has changed the way we live, work, and for others - commit crime. Although the internet may seem like a very convenient place users should always be wary for seemingly innocent offers.

Computer Forensic Investigation Service: Leave it to the Experts

Tuesday, August 19th, 2008

Computers have become an important part of our lives and have been used for a variety of purposes. Unfortunately this does not stop criminals and offenders.

Cyber crimes are now becoming more and more common. Millions of dollars are lost due to sabotage, fraud and employee theft. Fortunately there are computer forensic investigation organizations that offer consulting services.

As an entrepreneur we all want to reduce cost as much as possible. Some of may even send our own IT professionals to do some digging for us to investigate. Unfortunately even though these professionals mean well and they are well informed about your company’s system they will compromise the whole situation without intending to do so.

Leave it to the experts

Any employee can turn into an offender and before you know someone has hacked into your company’s network. In this situations, and other wherein the company’s security have been breached most of us would usually send in their own people. Unfortunately in computer crimes this is not a good idea.

In fact these well meaning employees that are there to do their job may unintentionally make matters worse. Computer forensic experts do their job in a way that complies with the standards of evidence so that it will be admissible in the court of law.

If the electronic evidence is tampered in anyway it will be inadmissible in court. Your IT professional may know what to do but they do not have the legal qualifications for this job. It is always advisable to hire professional help from the outside. If a computer forensic analyst is not able to address the situation at the start of the problem the operating system will randomly overwrite the data on the hard drive. The longer that the involved computer system is used there’s more possibility that the evidence will be lost.

In this situation no matter how much we want to do it ourselves, we have to hire professionals. Computer forensics analysts don’t just collect data but they also thoroughly examine and analyze the information gathered.

They can also obtain relevant evidence from an opposing party which works the same way as requesting for production of documents and determine if the computer was used for a criminal act or violation of policy. They can also retrieve deleted data from an operating system and preserve it.

The internal cost, time and pulling out employees from their jobs will also affect the outcome of the situation. Paying for a computer forensic expert will be considerably less compared to time and money you will spend in making your own investigation. The price of a computer forensic expert can cost from $250 to $350 per hour.

Their work involves three phases: acquisition, investigation and reporting. Acquisition costs about $500. Investigation and reporting will depend upon the nature of the case. Usually it can be completed in 15 hours. The total analysis will cost around $4,500. Business will not be interrupted while the investigation is going on.

There are computer forensic companies that offer a quick analysis. They will examine a hard drive and send you the report. You can then examine if there is substantial evidence that warrants further examination.
