The importance of computer forensics

Computer forensics is the process of combining the latest scientific and technical knowledge with computer science to collect, analyze and provide evidence to criminal or civil courts. Network administrators and security personnel managing networks and information systems should have complete knowledge of computer forensics. The term “forensic evidence” means “to bring a court”. Forensics is the process of finding evidence and recovering data. Evidence includes many forms, such as fingerprints, DNA tests or complete files on the computer’s hard drive. The consistency and standardization of computer forensics across courts has not been strongly recognized because it is a new discipline.

Network administrators and security personnel of network organizations must practice computer forensics and should understand the law because the rate of cybercrime is increasing greatly. This is very interesting for managers and personnel who want to know how computer forensics has become a strategic element of their organization’s security. Personnel, security personnel and network administrators should understand all issues related to computer forensics. Computer experts use advanced tools and techniques to recover deleted, damaged or corrupted data and evidence against attacks and intrusions. The evidence was collected to track criminal and civil court cases against criminals who committed computer crimes.

The survivability and integrity of the network infrastructure of any organization depends on the application of computer forensics. In the current situation, computer forensics should be regarded as a basic element of computer and network security. If you understand all the technical and legal aspects of computer forensics, it will be a huge advantage for your company. If your network is attacked and an intruder is discovered, a wealth of knowledge about computer forensics will help provide evidence and prosecute the case in court.

If you seriously practice computer forensics, there are many risks. If you do not consider this, then important evidence may be destroyed. New laws are being developed to protect customer data; but if certain types of data are not properly protected, organizations can be assigned many responsibilities. If the organization cannot protect customer data, the new rules will take the organization to criminal or civil courts. You can also save computer funds by applying computer forensics. Some managers and personnel spend most of their IT budgets on network and computer security. According to International Data Corporation (IDC), software used for vulnerability assessment and intrusion detection will reach $ 1.45 billion in 2006.

As the number of organizations increases, the risks of hackers and contractors also increase, so they have developed their own security systems. The organization has developed security devices for its network, such as intrusion detection systems (IDS), agents, and firewalls, which report the security status of the organization’s network. Therefore, technically, the best objective of computer forensics is to identify, collect, protect, and inspect data to protect the integrity of the collected evidence so that it can be used effectively in the case. There are some typical aspects of computer forensics research. First, computer experts working on computers should know the type of evidence they are looking for to make the search effective. The scope of computer crime is wide, such as child pornography, theft of personal data and the destruction of data or computers.

Second, computer experts or researchers should use appropriate tools. Investigators should have extensive knowledge of software, the latest technologies and methods to recover deleted, encrypted or damaged files, and prevent further damage during the recovery process. In computer forensics, two types of data were collected. Permanent data is stored on a local disk drive or other media, and is protected when the computer is powered off or turned off. Volatile data is stored in random access memory and is lost when the computer is turned off or powered off. Volatile data is located in cache, random access memory (RAM), and registers. Computer experts or researchers should understand the trusted way to capture volatile data. Security personnel and network administrators should have knowledge about the impact of network and computer management tasks on the computer forensics process and the ability to recover data lost during security incidents.
