If you are interested in joining the ranks of investigators who use cyber technology to solve crimes, consider earning your Master of Science in Cyber Forensics. Although not all computer forensics jobs require a college degree, most private companies will hire on the basis of certifications and skill.
Computer Forensics
The field of computer forensics entails analyzing and presenting digital evidence in order to solve crimes. These professionals often work for law enforcement and government agencies, though some are also employed by medical labs, private investigation firms, and accounting firms. Computer forensics technicians also assist in resolving data privacy cases.
Computer forensics investigators need to have a broad knowledge of computer networks and operating systems to be effective. They may also need to be knowledgeable in malware analysis and reverse engineering. Computer forensics investigators must also be able to read and understand data, formulate conclusions, and present findings in a simple way.
Malware forensics
Malware forensics involves identifying, collecting, and analyzing malware. The analysis process involves checking for malicious code, determining the mode of entry and propagation, and analyzing the effects on the victim’s system. Investigators conduct this task with various tools and techniques. These techniques include analyzing the appearance of pop-up advertisements, resetting browser settings, and examining the registry keys.
The analysis stage of the process depends on the facts of the case. For example, if a company’s security is compromised by a ransomware attack, an investigator will analyze the network traffic to determine if it was compromised. Once they have gathered enough evidence, they will form a conclusion.
Email forensics
Email forensics is a branch of digital forensics that focuses on analyzing emails as evidence. It can be vital in criminal and civil cases. Investigators can use a variety of investigative approaches to collect and analyze email messages. They can use forensic software to identify the sender and receiver of emails, as well as the date and time the email was sent and received.
Emails are saved in a number of locations: the sender’s computer, the recipient’s computer, and email servers. They can also be archived on backup media. This means that even if the recipient deletes an email, it will still exist somewhere.
Network forensics
Network forensics can be an integral part of a digital forensic investigation. It can help to piece together the missing pieces and support root cause analysis by providing evidence of how a system was first compromised. Using various methods, network forensic analysts can investigate traffic patterns and identify the source and mode of compromise. This technique involves analyzing log files and network protocols, as well as wireless and web traffic. The analyst may also analyze email, which can leave traces that could be crucial to a case.
Network forensics are becoming increasingly important in the fight against cybercrimes. By analyzing data stored on networks, investigators can find out how a cybercrime works and how it affects the business. While network forensics differ from conventional forensic investigations in several ways, they are vital in protecting an organization.
Deleted file recovery
One of the most common methods of destroying evidence is by deleting a file. This can be done with the “Delete” or “Shift+Delete” keys. However, the contents of a deleted file are not permanently erased. Windows still stores a copy of the file’s location in the recycle bin, which labels the disk space as “available.” If you are looking to recover a file from a recycle bin, you need to know how to find and read the file’s content.
When a suspect erases a file, they are often trying to cover their tracks. By recovering deleted files, forensic investigators can reconstruct evidence. In addition, the recovery of data is essential for building a case against a suspect. Thankfully, data recovery specialists have a number of tools to help.
Computer Forensics certifications
Computer forensics certifications provide a range of benefits for investigators and forensic scientists. They enable professionals to participate in private listserves, receive group benefits such as professional liability insurance, and have access to a vast community of forensics experts. Many certifying bodies also offer newsletters, research and development projects, and private professional journals.
Computer forensics certifications provide investigators and security professionals with training to analyze computer systems and obtain evidence. The GIAC GCFE credential is an important credential for security practitioners because it validates their understanding of computer forensics. The GCFE certification program focuses on core skills needed to collect Windows computer systems and perform forensic analysis. GCFE certification holders are trained in typical incident investigation techniques, such as evidence collection, tracing user and application activities, and analyzing contact lists.
Legal issues in the field
In the case of cyber forensics, investigators need a strong working knowledge of various legal issues that surround the process. These include laws that govern the collection and presentation of evidence, privacy rights, and telecommunications. An investigator should also understand the different types of electronic evidence.
The most significant legal issues in computer forensics involve the admissibility of evidence in criminal cases. These issues also involve the law of search and seizure as it applies to digital equipment. Another major issue is accessing stored information, and the interception of electronic communications. There are also ethical concerns regarding this type of work and the use of investigative technology.
