3. Threats faced by digital forensics
3.1 Technical challenges
The advancement in digital technology has opened doors to various opportunities; however, it has also caused the digital forensics domain to face various challenges. Although different digital forensic experts and researchers have been analyzing and studying numerous known digital forensic issues, there is still a requirement to classify these challenges . In this account, it has been discovered that digital forensic systems are exposed to technical challenges that threaten the integrity of these systems. Technical challenges are those potential threats that can be addressed using existing operations, protocols, and expertise. Understanding that digital forensics demands an optimum combination of ethical conduct and technical skills. Some of the major technical challenges, associated with digital forensics are encryption, a huge volume of data, and incompatibility among diverse forensic tools . The advancement in communication technology has made sophisticated encryption products and services easy and widely accessible. Due to this, encryption algorithms and standards are becoming more complex, which further increases the time and difficulty of conducting cryptanalysis. This technique joins encrypted files together to extract meaningful information. In addition, encryption makes electronic data unreadable, which further enable criminals to camouflage their criminal activities . For a digital forensic officer, this can negatively affect their investigation process. It has been discovered that around 60% of cases - involving some type of encryption - goes unprocessed because it significantly limits the ability of the investigator to extract information from the evidence . Thus, the easy implementation, low cost, and the availability of encryption tools greatly pose a threat to the integrity and credibility of the digital forensics process.
In addition to encryption, huge volumes of data that exist within numerous applications- like enterprise resource planning-also poses a great threat to digital forensic operations. The substantial increase in data volumes significantly reduces the capability of legal systems and forensic investigators to keep up with the digital threats . Likewise, with the introduction of cloud computing, much IT-related hardware, such as network switches, racks, and servers have been replaced with remote-on-demand, virtualized software that are configured according to business needs. Besides, these services and data can be managed and hosted by a third-party or the user from any place. Thus, the data and software have the possibility that it is stored physically across multiple geographic locations . This distributive nature of data substantially lowers the control and visibility of forensic experts over digital forensic artifacts. Similarly, digital forensic tools and techniques commonly differ in cost, complexity, and functionality. Due to this, most of the digital forensic tools contain heterogeneous parts or elements, which increases their incompatibility to work together . Moreover, some forensic tools are not able to handle the ever-increasing storage capacity of target devices. This means that vast targets constitute a major technical challenge to digital forensic operations because they demand more complex analysis techniques. Thus, it is affirmed that different technical challenges pose a great threat to the performance and integrity of digital forensic operations.
3.2 Operational challenges
It is a known fact that digital crimes are intentional in their scope of operation. Due to this, digital forensics is exposed to various operational challenges. Among such challenges, incidence prevention, response, and detection have gained much attention. Traditional IT environments that have on-premises data processing have integrated internal incident management process for ensuring utmost security . This process utilizes intrusion detection systems, log file analysis, and monitoring, in addition to data loss prevention systems that identify and detect data loss, attackers, and intruders. For cloud users, these security incidents can often prove to be challenging. This is because, these security incidents compromise business and personal data and since they are equipped with anti-forensics technology, attackers can steal or destroy potential evidence . Likewise, the lack of standardized procedures and processes in digital forensics alarmingly endangers the evidence extraction and investigation process. It is established that currently, digital forensic models lack standardization that has further increased the complexity of the process. Besides, studies like  argue that the lack of universal standards makes it quite tough to assess the competency of forensic experts. The absence of standardized procedures was acceptable when digital forensics was considered a mysterious investigation process that enabled experts to discover hidden pieces of evidence and information that further provided useful insights regarding criminal behaviors. However, with the increase in the development of digital technologies, digital forensic investigation is no longer limited to small computer systems rather a virtualized environment that consists of non-standard interfaces and different storage devices.
In addition to above-discussed threats, digital forensics is also exposed to forensics readiness problem. Forensic readiness can be understood as the capability of computer networks or computer systems to record data and activities in such a way that it can be perceived as authentic and are sufficient enough for forensics purposes . However, the rapid development in cloud computing has forced organizations to dynamically change how they enact, develop, and plan IT strategies. Besides, cloud computing lacks forensic readiness aspect, which further threatens digital forensic operations. Similarly, manual analysis and intervention of physical hard drives is another potential operational challenge that is faced by digital forensics. Albeit, it is simple and straightforward in a single drive, or a single partition, the process becomes much more complicated when RAID configurations are involved . Also, due to the complex nature of digital forensics, manual inspection of hard drive images can potentially risk the digital artifacts. Likewise, it is believed that forensic analysis should be valid, accurate, complete, and reliable. However, balancing between user privacy and retrieving key digital evidence is a major threat to digital forensics. Due to the increase in the storage capacity, often a small portion of the information is used for investigation and a larger amount of information is discarded . This can lead to a breach of the user’s privacy, which poses an additional challenge to digital forensic operations. Thus, in light of the evidence, it can be affirmed that operational challenges can notably endanger digital forensic analysis.
3.3 Personnel related challenges
Personnel related challenges endanger the integrity of digital evidence. Among various personnel-related challenges, lack of well-trained forensic staff is the most prominent one . Despite the overwhelming significance of the digital forensics field because of cyber-crimes, the lack of qualified forensic officers threatens the process of digital forensics. The shortage of well-trained forensic investigators is due to the fierce competition in law enforcement as well as high requirements since digital forensics require technically proficient personnel that are certified and trained to deliver scientifically valid evidence . Likewise, it cannot be denied that digital forensics has gained major importance among forensic practitioners, law enforcement agencies, and computer professionals. Unfortunately, the advancement in this field has encouraged an environment that is threatened by semantic disparities. Another potential personnel-related challenge is a chain of custody. Chain of custody refers to the location log that defines the collection point of the evidence. In digital forensic analysis, it is one of the most crucial issues because it requires physical control of the evidence that is not possible in a digital environment . In addition, due to proprietary technology, procedures, and multi-jurisdictional laws, effectively managing the chain of custody is a major challenge that is faced by digital forensics. Hence, it can be established that personnel-related challenges pose a great challenge to traditional forensic operations.
In addition to the discussed challenges, it is undeniable that digital forensics lack a unified formal representation of standardized procedures and knowledge for analyzing and gathering digital artifacts. This inevitably causes incompatibility and conflict within various digital forensics tools . Errors in the interpretation and analysis of digital artifacts occur when the standardized or formalized procedure for analyzing, preserving, and collecting digital evidence is absent. Likewise, when forensic experts manage a vast amount of data while simultaneously performing forensic investigation, they utilize specialized skills and digital technologies. However, these experts often fail to record their work, which further hampers training and external reviews . Past knowledge and experience should be utilized to further train new digital forensic personnel while fostering knowledge sharing among detective communities. Unfortunately, digital forensic officers either fail to record their work or simply do not follow legal practices that further poses a great threat to digital forensic investigation.

Metadata stored in USB flash drives can assist digital forensic experts in identifying detailed information about digital data. This information includes copyright information, geospatial information, or even timestamps that are vital in examining digital forensic evidence. Besides, it is undeniable that USB storage device is considered as the standard for transfer and backup of data files, due to this, potential hackers use USB devices to conduct data theft . Hence, by comprehending the diversity and complexity involved in analyzing USB devices, digital forensic operations can greatly benefit in terms of tracking traces that could lead forensic analysts to potential wrongdoers.
Moreover, in terms of forensics, USB devices contain significant footprints in a various digital environment that are vital in forensic examination . In addition, in USB specification, MSC is considered as a standard for establishing a connection between removable drives. MSC can be defined as a protocol set that takes care of communication between operating systems and USB devices . From a digital forensic standpoint, the MSC protocol gives the digital forensic officer direct access to file systems, clusters, and sectors. Having full control over such file systems, digital forensic experts can easily identify, extract, and thoroughly analyze digital evidence. As a result, USB forensics cannot only reduce the complexity of the digital forensic investigation, but it can also ascertain that the extracted evidence is authentic.
4.2 Intrusion detection
Due to recent development in information systems and rapidly increasing network attacks, intrusion detection systems (IDSs) have become a crucial area of interest in digital forensics field. According to , IDS has the capability to detect intrusion attempt that can either render a system unreliable, or unusable, gain access to critical digital evidence, or manipulate information. Such systems are ideal for digital forensic investigators as they reveal suspicious behavior within the network. Likewise, with efficient IDS in place, forensic analysts can easily determine whether the security of the computer system is compromised or the data is being accessed from an unauthorized location . This information is critical in forensic investigations; as forensic experts can use this information to extract useful data which can be presented as potential evidence in the court of law. Besides, if an attacker attempts to sabotage a public or private network, IDS will identify and activate incident response (IR). The digital forensic investigation - combined with IR protocols - would allow investigators to preserve, gather, and identify live data . Further, digital forensic methodologies, combined with IDS, will ascertain that no changes are made to the seized content and evidence. IDS systems can also help in detecting hostile and malicious network activities, specifically by analyzing the acquired packets, blocking attack connections, and by alarming the system administrator for limiting the potential damages. These functionalities are crucial in case of digital forensic investigation, as the attacker would always attempt to erase potential digital evidence.
Albeit digital forensic has made it easy to analyze and detect cyber-crimes, the fact remains that it cannot provide fool-proof security to the network or online storage. In this case, IDS has opened doors to various opportunities for digital forensics, as it not only detects malicious activities, it also monitors traffic data to determine the nature of the attack . Moreover, IDS also possess the ability to warn the system administrator - in case the system has been compromised. Once the event has been detected, the digital forensic process can be conducted for discovering the damage and the extent of the intrusion. Although the primary objective of IDS is to identify potential malicious attempts to prompt evasive measures, with the help of digital forensics, it can be used to extract useful digital evidence for civil, legal, and criminal proceedings . The ultimate goal of IDS is efficiently detecting misuse or unauthorized use of computer networks and systems by both external penetrations and insiders. With digital forensics, investigators can trace criminal, intrusive, or illegal activity back to the criminal while simultaneously obtaining sufficient evidence. Thus, it can be established that IDS provide various opportunities and have the ability to assist in digital forensic investigation. Moreover, IDS systems can ensure that the obtained evidence is safe and it can detect and effectively respond to cybersecurity threats.
4.3 Artificial intelligence
With the rapid rise in the volumes of digital data, digital forensics often struggles to analyze a complex and large amount of information that requires intelligent analysis and computing. For this purpose, artificial intelligence (AI) has become a well-established and crucial domain of latest computer science, which has the ability to tackle sophisticated and computationally large problems in real-time . The complexities and growth in cyber-crime combined with limited resources and time, both human and computational, in addressing cyber-crime significantly limits the capabilities of the digital forensic investigators to apply digital forensic operations and obtain results in a realistic time-frame.
