The cyber forensic ultimately helps in the evidence management to prove a crime. The ultimate aim is to prove that the evidence provided to the court is the evidence collected from the place of commissioning of the crime. Challenges in Cyber Forensic Investigations can be divided in to two classes:
1) Technical
2) Human Factor

Technical Limitations:
Documentation of all action is required
Preservation of evidence is expensive
Swift action to collect electronic audit trails
Resources are required such as software and hard ware
Time – hard drives are getting
Authenticity of the evidences is highly questionable
The process is time consuming
There are no standards of the forensic examination
Misconceptions and lack of awareness
Maintain the secrecy and the integrity of the data is very difficult
The software are very costly
Difficult to identify the originality of the hardware and software as each device is combination of multi-technologies.

Human Factor:
There is scarcity of the experts in this field
There is a need of consist work for long hours which is difficult
Training of the software is not readily available
Lack of awareness of maintaining the evidences on the crime scene and or in public domain

Legal issues in cyber forensics:
Deciding the jurisdiction is one of the most important issues in computer forensic.
Maintaining the integrity of the evidences is very difficult as it has to pass though through a chain of authorities.
The crimes are mostly cross border hence it is very difficult to initiate the action against the criminals.
There is integration of various laws for example, IPC, CPC, Evidence Act, IP laws and Cyber laws in cyber forensics
The laws in various countries are different and there is no harmony.
The police has limited language of the cyber law hence there is almost no cooperation from them for search and seizure from the crime scene.
There is involvement of constitutional law when comes to privacy, search and seizure
There is application of property laws when it comes to IPR issues
Identity management in the form of digital signatures the the contract act is also involved in the cyber forensics When there are issues related to torts such as tresspass, negligence and defamation etc then the cyber forensic is again a task. As far as evidences are concerned the accuracy of presentation, and preserving the evidence in the best more and presenting to the court is one important legal issue
