Computer forensics is the process of using the most recent knowledge of science and technology with computer science to collect evidence and present it to criminal or civil courts. The network administrator and security personnel who manage and manage networks and information systems must have full knowledge of forensic evidence. The meaning of the word "forensic medicine" is "bring to court." Forensics is the process involved in finding evidence and recovering data. The manual includes many models such as fingerprints, DNA testing, complete files on computer hard drives, etc. Computer forensics standardization and standardization have not been strongly recognized through the courts because it is a new system.

It is imperative that the network administrator and security personnel in networked institutions practice computer forensics and should be familiar with the laws because the rate of cybercrime is increasing significantly. It is very interesting for managers and workers who want to know how computer forensics can become a strategic element in the security of their organization. Employees, security personnel, and the network administrator must know all issues related to forensic evidence. Computer experts use advanced tools and techniques to recover deleted, damaged or corrupt data and evidence against attacks and intrusions. This evidence is gathered to follow up on cases in the criminal and civil courts against those perpetrators of computer crimes.

The viability and integrity of the network infrastructure of any organization depends on the application of computer forensics. In current cases, computer forensics should be considered a primary component of computer and network security. It would be a great advantage for your company if you know all the technical and legal aspects of computer forensics. If your network is attacked and an intruder is discovered, good knowledge about computer forensics will help provide evidence and try the case in court.

There are many risks if you practice computer forensics badly. If you do not take it into account, vital evidence may be destroyed. New customer data protection laws are being developed, but if a certain type of data is not properly protected, many responsibilities can be assigned to the organization. The new rules can bring organizations to criminal or civil courts if organizations fail to protect customer data. Enterprise funds can also be saved by applying forensic evidence on a computer. Some managers and employees have spent much of their IT budget on network and computer security. IDC has reported that a vulnerability assessment and intrusion detection program would approach $ 1.45 billion in 2006.

With the number of organizations increasing and the risk of hackers and contractors increasing as well, they have developed their own security systems. Organizations have developed network security devices such as Intrusion Detection Systems (IDS), agents, and firewalls that report on the organization's network security status. So technically, the primary goal of forensic science in a computer is to recognize, collect, protect, and examine data in a manner that protects the integrity of the evidence gathered for its efficient and effective use in the case. Computer forensics investigation has some typical aspects. In the first field, computer experts who investigate computers should know what kind of evidence they are looking for to make the search process effective. Computer crime is widespread such as child pornography, theft of personal data and the destruction of data or computer.

Second, computer experts or investigators must use appropriate tools. Researchers should have a good knowledge of software and the latest technologies and methods to recover deleted, encrypted or damaged files and prevent further damage in the recovery process. In computer forensics two types of data are collected. Static data is stored on local drives or on other media and protected when the computer is turned off or turned off. Volatile data is stored in RAM and is lost when the computer is turned off or power is lost. Volatile data is located in the cache, random access memory (RAM) and logs. The computer expert or researcher must know reliable ways to capture volatile data. Security personnel and network administrators must have knowledge about the effects of the network and computer management task on the computer's forensic process and the ability to recover lost data in a security incident.
