Why is Digital Forensics Important?
With the rise in technology, the increase in digital crimes is inevitable. Just like in real life, people who use electronic devices leave behind different footprints, traces and markings. These virtual or digital traces could be file fragments, activity logs, timestamps, metadata, and so on.
Digital forensics is a new science that involves finding evidence from digital media, such as computers, mobile phones, or networks. Forensic teams analyse, 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.
There is a great deal of digital forensics can do, including:
- Identifying the cause and possible intent of a cyberattack
- Safeguarding digital evidence used in the attack before it becomes obsolete
- Increasing security hygiene, retracing hacker steps, and finding hacker tools
- Searching for data access/exfiltration
- Identifying the duration of unauthorized access on the network
- Geo-locating the logins and mapping them
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.
How can digital forensics help?
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 ex-filtrated 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.
Why should who need digital forensics?
For businesses that hold customer data, digital forensics is important. If there has been a cyberattack, the digital artefacts and evidence should be preserved immediately for an effective investigation to take place. An important point to note is that a digital forensic investigation will not do much to prevent an attack. It’s meant for after an attack has already occurred. This doesn’t mean that the information gathered during the investigation can’t be used by the business to prevent attacks in the future. It can help identify weaknesses in the current security system that can be fixed or replaced. Digital forensics can determine if there is still suspicious activity and alert you if steps need to be taken to mitigate those possible cyber threats.
