Based on the type of attack, the further action depends. As the rate of computer crimes increases there is a need for a well defined set of Computer Forensic Methodologies.These methods help in solving such computer crimes.The evidences that are seized from the computer devices are likely to change,can be altered easily,so they are to be handled properly using methodologies.These methodologies can vary based on the adopted procedures in companies. The examiner involves in recovering hidden, deleted and temporary files.They helps in the examination of servers,workstations, standalone computers and other storage medias and procedure involved in the process can be difficult or easier based on the media that is to be analyzed.During the process of evidence examination,the logs are to be maintained which play a crucial role in
The major obstacle is that digital media distribution and copying threatens intellectual property rights. This tends to affect the revenue of the intellectual property owners. Digital rights management is there to safeguard the interests of the intellectual property owners. DRM features include; copy control, access control, usage metering and traceability (TORRUBIA, MORA, & MARTI, 2001). DRM uses encryption to authenticate users and provide access control by separating the encrypted content from the keys required to decrypt the
In other words, the overall architecture (software, various protocols, devices and programs) have to be regulated by code and as Lawrence Lessig (1999) said: "Code is the law". For example, passwords is one of the main way of blocking or limiting information on the internet or monitoring devices that all actions made by specific device. What is more, protocols as TCP/IP as well as cookies makes roaming the internet activities traceable. This in return, decreases the amount of illegal activities and information transmitted online. What is more, code can be designed to privatize intellectual property, which can be frequently seen nowadays as copyright laws.
They make sure their agents are highly trained in computer forensics. Computer forensics are important to secret service agents because it is used to find any evidence for crimes that are stored digitally. To do this they created ECSAP, (Electronic Crimes Special Agent Program) what they do is train agents in network intrusion. Other tasks the secret service does to prevent cyber crimes and fraud is making emergency computer response teams, increasing relations with
Those states that allow law enforcement officials to obtain samples provide for a way to have samples removed if the charges are dropped. Most states require a person to request they be removed but nine states automatically remove samples incase of no conviction. The pros of collecting DNA samples are boiled down to a few main points, while there are many reasons why collecting it at the time of arrest would be considered a bad idea. One reason why it is a bad idea is privacy. Citizens are concerned that taking samples of their DNA invades their privacy, and that DNA should only be gathered through proper procedures, which include obtaining a warrant.
A variable is very often described as a name for a place in the computer’s memory where you are able to store any data that you wish. The computer will automatically place these variables in different locations each time that the programme we are loading is run however the programme that we have loaded will know exactly where the computer has placed the data. We are able to do this by composing a variable to refer to it and then leave the computer the messy work of having to find out where it is actually located. For us it is much more important to be able to know exactly what type of data that we will be storing at that location. Variables however are temporary and only exist for the amount of time that they are actually necessary and will then be disposed of.
Student Name: Keshab Rawal Student ID: 77171807 Word Count: Title: The rise of anti-forensics: The rise of anti-forensics: Tables of contents: • Overview • Introduction • History • Categories/Tools of anti-forensics • Conclusion • Future Work Overview: Computer forensics is an active topic of research, with areas of study including wireless forensics, network security and cyber investigations. The goal of the computer forensics is to provide information about how the crime happened, why and who is involved in the crime in any legal proceeding by using the computer forensic tools. Data Destruction – Destroy any evidence before someone gets a chance to find it E.g. Disk wiping, wipe, srm, evidence eliminator, necrofile . Data Misdirection
The initial investigation on the laptop is what led to the investigation of Richard’s work computer. Evidence not only showed that of spoliation on both the couple’s laptop and Richard’s work computer but also multiple similar instances of witness tampering as well as perjury. The judge stated that if proof of spoliation of evidence on Richard’s part was evident then his judgement would not be in favor of Richard the defendant. After the spoliation case was closed the child custody case would begin. Protegga states that anti-forensic tools, such as Evidence Eliminator, are used to interfere with the digital forensic tools used to recover data.
Many forms of spyware, however, are more malicious and can have serious effects on users and businesses. Key logging spyware, for example, transmits to the author of the spyware a log of every keystroke entered on that computer. The author can then sift through this data to find valuable information, such as credit card numbers, security codes and confidential information, from that user or their business. Other types of spyware search through the data stored on the host computer for particular types of file, which are likely to contain confidential or personal information, such as Word documents or images, and transmit them to the spyware
People often use the same username and password for many different systems, so these stolen credentials may be used to access other systems not yet infected. Once access is gained, additional information theft or malware installation can take place. Another way spyware puts systems at future risk is by installing backdoor access mechanisms. These backdoors give the malware operator access to control the system or to command the system to download and run arbitrary applications. Attackers can build vast collections of compromised systems without originally compromising a single
This unique characters, otherwise called signatures can be a byte pattern in the virus. This is usually done using the AV software, the AV software uses the signature obtained from the signature database to detect the malware, and when a match is gotten, the AV software then alerts and prompts the user to repair or remove the file. - - Heuristic-based Detection: unlike the signature based detection, the heuristic-based detection is mainly designed to detect previously undetected or unknown viruses. Heuristics based detection detect viruses based on how they behave; that is to say the heuristic blocks the action of a file that it’s not behaving the way it is known to behave using sandbox techniques from a heuristic scanner.. - - SQL (Structured Query Language) Injection is when malicious attackers make use of SQL statements to interact with a database. They have having the ability to write and delete data in the database, the attackers cause damage by entering different from what its expected.
