Computer forensics courses may be new to some of us out there. One of the reasons may be because the course is not made known to the public as much as a career such as doctors, nurses, teachers and policemen. Everyone knows what forensics is but what they do not know are the branches in forensics and this course is one of the branches.

Technology is getting more and more advance each day and the job scope gets larger and larger each and every single day. Investigation involves investigating the possible crimes at any crime scenes involving the use of computers or any digital devises as evidence. Here, you may find the basic things that an investigator does. Investigator first needs to prepare evidence and chain of custody forms.

• Evidence forms will contain the name of the device, the measurements, model, and serial numbers. This form is to ensure that there will be no confusions of devices and that particular device is for one particular case and will not be mixed up.
• Chain of custody forms answers the five questions of “what”, “when”, “who”, “where”, “why” and “how” of the particular evidence.

After filling up those forms, the investigator will have to analyse on how to retrieve the data from the device. There are several things that a computer forensic investigator has to follow and below are a few examples:

• not to boot a computer when it is off
• not to off a computer when it is on
• protect the evidence from getting destroyed by using a write protection software

Network Security is a complex problem that we must deal with every day, especially in big companies. Anytime, hackers can plant vulnerable viruses and Trojans to steal valuable data, and cause data loss and network destruction. There are also internal threats, especially from unsatisfied employees with full access to company data. Company data must be secured from sabotages by industry spies. To achieve the best network security for your company, you can consider using network security software, firewalls, encrypted pages and passwords. By doing these methods, you can at least minimize the risks of being a victim of data theft.

It is not an uncommon case that a company’s computers are hacked by an unsatisfied ex-employee. The simplest way to avoid data theft and malicious damages to the computer is to store all the data on a server instead of an employee’s hard drive. It is really important to eliminate the need of users to keep company’s data on their personal workstation. In most cases, data theft happen to portable computers, so to minimize the risk, it is best if you limit the number of laptop users since laptops can easily be taken home. Don’t think that putting passwords on the stolen laptops can prevent you from losing your company’s data as passwords can be cracked easily.

It is not uncommon for hackers to steal identities, financial records and other important company data. To secure your company’s network, you can use encrypted pages, firewalls, and infrastructure protective measures such as software and passwords.
