Importance Of Computer Forensics
Digital forensics is a new science that involves finding evidence from digital media, such as computers, mobile phones, or networks. Forensic teams analyze, inspect, identify, and preserve the digital evidence, and use it to help them investigate crimes related to technology. Whether data has been compromised by a cyberattack or files encrypted by ransomware, data forensic experts can help determine how the attack took place, what the damages were, and in many cases, who perpetrated it.
Importance of Computer Forensics
All of these are helpful not only in dealing with an attack but the aftermath and the consequences of one. If your company was recently a victim of a cyberattack, it may be difficult to decide what the next course of action should be. A digital forensics investigation can lead you in the direction to understand what information was compromised. Businesses that have experienced a cyberattack must understand the attack in full context to see what data was breached.
Digital forensics can help identify what was stolen, and help trace whether the information was copied or distributed. Some hackers may intentionally destroy data in order to harm their targets. In other cases, valuable data may be accidentally damaged due to interference from hackers or the software that hackers use. Data may also be encrypted and held for ransom and rendered unusably. The recent attack on the oil pipelines in the United States of America is an example of an attack for ransom. The attack on the Colonial Pipeline, which carries almost half of the gasoline, diesel and other fuels used on the East Coast, underscores the potential vulnerability of industrial sectors to the expanding threat of ransomware strikes.
Digital forensic experts might be able to recover data that was lost or damaged, although this is not a guarantee. After the breach, the cyber attackers can easily and almost immediately sell or misuse that information. However, a digital forensics expert can determine what has been exfiltrated from the network, hence digital forensics is an important field. Threat intelligence data from previous cases can be used to determine the likelihood that your data is leaked.
The job of catching an attacker is usually delegated to the police or different authorities, with digital forensics providing evidence. This is crucial to finding the perpetrator, and more importantly, prosecuting them. The faster and more thorough a digital forensics investigation is, the better the chances of the hacker being caught and any damages being repaired and that is why digital forensics is important and why the field has gained a lot of prominence over the years. This is also why choosing the right vendor to conduct the investigation is essential. Have questions about digital forensics? Contact us.
Computer forensics, a branch of digital forensic science, handles crime evidence legally found on computer hard drives and all digital storage files and software. Its goal is to thoroughly, forensically examine these digital files and content, to uncover and analyze the data for the reporting of facts and educated opinions about the information retrieved.
Though most often used in the investigation of computer crimes; computer forensic science can also be utilized in the investigation of civil matters. The process of computer forensics is much like that of data recovery, but with added guidelines and regulations in order to create a legal data trail for auditing. Computer forensics is widely accepted in the U.S., Latin America and throughout Europe, as reliable evidence in the investigation of many high-profile cases.
In the digital times we live in today, it would be practically impossible to retrieve the kinds of evidence required to solve many of the cases brought forth to the court system in a digital era. Computer forensics science is an extremely reliable and helpful resource needed to try such cases in court.
According to the Bureau of Labor Statistics (BLS) Occupational Outlook Handbook (OOH), between 2016 and 2026, jobs for information security analysts are projected to grow 28 percent, much faster than average for other occupations. Demand for these professionals will remain high at computer companies, consulting firms, and business and financial companies. General responsibilities for this position include planning and implementing security measures to protect computer networks and systems from cyberattacks. In 2017, the median annual pay for information security analysts was was $95,510 nationally and $108,090 in California. Information security analysts who focus on computer systems design, have an anticipated job growth of of 56 percent for this same time period, due to small and midsized companies moving services to the cloud and an overall increase in cybersecurity threats.
Another growing field is for professionals who design computer programs. For 2016-2026, the Bureau of Labor Statistics OOH projects jobs for system software developers to increase by 24 percent, much faster than average for other occupations. In 2017, the median annual pay nationally for these professionals was $107,600 with the California annual average salary at $127,230.Top employers include manufacturing, engineering services, finance and insurance, software publishers, and computer systems design and related services.
Computer systems analysts, also known as computer systems architects, will also be in demand with the BLS projecting a job growth rate of 9 percent between 2016 and 2026. According to BLS statistics, in 2017, the annual median salary for computer systems analysts was $88,270 nationally and $102,860 in California. Increased use of cloud computing and IT services in healthcare will continue to fuel demand for this role.

Cyber forensics is a process of extracting data as proof for a crime (that involves electronic devices) while following proper investigation rules to nab the culprit by presenting the evidence to the court. Cyber forensics is also known as computer forensics. The main aim of cyber forensics is to maintain the thread of evidence and documentation to find out who did the crime digitally. Cyber forensics can do the following:
in todays technology driven generation, the importance of cyber forensics is immense. Technology combined with forensic forensics paves the way for quicker investigations and accurate results. Below are the points depicting the importance of cyber forensics:
Computer forensics is the application of investigation and analysis techniques to gather and preserve evidence from a particular computing device in a way that is suitable for presentation in a court of law. The goal of computer forensics is to perform a structured investigation and maintain a documented chain of evidence to find out exactly what happened on a computing device and who was responsible for it.
Computer forensics -- which is sometimes referred to as computer forensic science -- essentially is data recovery with legal compliance guidelines to make the information admissible in legal proceedings. The terms digital forensics and cyber forensics are often used as synonyms for computer forensics.
Digital forensics starts with the collection of information in a way that maintains its integrity. Investigators then analyze the data or system to determine if it was changed, how it was changed and who made the changes. The use of computer forensics isn't always tied to a crime. The forensic process is also used as part of data recovery processes to gather data from a crashed server, failed drive, reformatted operating system (OS) or other situation where a system has unexpectedly stopped working.
In the civil and criminal justice system, computer forensics helps ensure the integrity of digital evidence presented in court cases. As computers and other data-collecting devices are used more frequently in every aspect of life, digital evidence -- and the forensic process used to collect, preserve and investigate it -- has become more important in solving crimes and other legal issues.
The average person never sees much of the information modern devices collect. For instance, the computers in cars continually collect information on when a driver brakes, shifts and changes speed without the driver being aware. However, this information can prove critical in solving a legal matter or a crime, and computer forensics often plays a role in identifying and preserving that information.
Businesses also use computer forensics to track information related to a system or network compromise, which can be used to identify and prosecute cyber attackers. Businesses can also use digital forensic experts and processes to help them with data recovery in the event of a system or network failure caused by a natural or other disaster.
As the world becomes more reliant on digital technology for the core functions of life, cybercrime is rising. As such, computer forensic specialists no longer have a monopoly on the field. See how the police in the U.K. are adopting computer forensic techniques to keep up with increasing rates of cybercrime.
Often, multiple tools are used in computer forensic investigations to validate the results they produce. Learn how a researcher at Kaspersky Lab in Asia created an open source forensics tool for remotely collecting malware evidence without compromising system integrity.
