Internet Related Crimes Course Work Examples
After the computer układ has been compromised with, and an intrusion is detected, a computer forensics investigation is necessary to stop further intrusion. The Connecticut Company ought to have put in place preventive measures in order to prevent intruders from accessing their information. In case, the preventive security measures fails, Intrusion Detection System, IDs, is implemented which completely detects any intrusion into the system, and, if the intruder is indentified necessary legal
actions are taken.
For that reason, any computer system network must have a firewall. This is a system, or rather a virtual wall that prevents entry of information into the network without approved authorization. This firewall will block away any information that has not been allowed by the administrator. This is a necessary preventive measure to block the external persons from accessing internal information. Use of anti- virus software is also a preventive measure that prevents harmful programs from getting into a computer system.
In addition to the firewall, an intrusion detection system can also be used by a server to detect an intrusion, if an intruder has by-passed a firewall and has full access to the system. Another preventing measure is having a restrictive access to computers, and this is achieved by creating a password that prevents any intrusion on the computer terminal. The company should always adhere to the said measures and many others that are not mentioned herein. For instance, computers should not be connected to the internet when not in use.
2. What security controls should be implemented by any organization to prevent, detect, and recover from a computer intrusion?
Security controls to prevent computer intrusion should be implemented beforehand and before one begins surfing. Every safety control should be put in place, so that the intruders will never get an opportunity of accessing from other computer systems. The first security control that should be implemented is a firewall Test. This is a security measure that is very first and very accurate. It should be effectively locked, in order to prevent your credit cards, passwords, bank accounts and other personal information that is considered crucial and significant.
Another security control measure that the organization should implement is having intrusion prevention hardware and software. Both are configured, therefore, ensuring tight web security. Other than relying on the hardware and software devices, an organization should ensure that it has taken a firewall test. This security measure helps determine malicious programs that an intruder may have put into a computer system. Even with the firewalls, it sometimes becomes very challenging, since one may not be certain on the correct button to select. One may a select a button that may provide a full access for the intruder to evade all the security measures that have been put in place.
For this reason, the organization should implement a popup Test that identifies such malicious entries. A free spyware removal program is also significant as a security control measure, since it detects and prevents any entries of malicious programs into the computer system and terminal. Together with that, an organization should implement web security services which prevent installation of unwanted software. For that reason, an intrusion prevention test, or rather an internal IP audit, is installed as this ensures that an intruder cannot allow java applets to execute unrestricted areas.
3. Why would someone want to use a forged e-mail address? Explain how this worked to the intruders’ advantage in this case.
In the current world, computers are being used for almost every aspect that affects human being. This ranges from banking services, shopping services and communication. While sending messages regarding these services, most people use email or even the chat programs.

They attack other computer systems using forged emails since they do not want to be known. They even use the forged emails when they have an intention of getting some personal information from another computer system. This becomes very difficult to trace the intruder, since they forge an email.
In some other circumstances, someone else might be mistaken incase the intruder hacks the password and email address pertaining to a particular person. Intruders do not mind about the identity of persons they have hacked their accounts.

While a lot of information can be obtained from a host computer, some other information can also be obtained, from the server. Most of the events that happen in a computer system are saved in web logs on servers. If a person fails to gather the system logs, significant information can be left out.
These logs stores some important information, such as username, password, the access time, and the devices used, the functions performed and other type of information depending on the type of log utilized. By evaluating the logs, it is easier to prove that a particular user account actually performed a specified questionable act. Together with that, the firewalls and the Intrusion Detection System, have some logs that can be examined for suspicious activities.
Most network routers have also some logs which may compel an investigator to rebuild evidence. By evaluating the web logs in an information system, it becomes possible to analyze a crime that may have occurred. Having numerous entries similar to a single web logs, may mean that, there are some people that may be trying to hack the website by having similar information. For that reason, servers should be very cautious concerning their login details, the usernames and also passwords.
5. What was the importance of having court orders immediately issued to Hotmail. com and Time Warner Cable?
Issuing court order to Hot. com and the Time Warner Cable was very significant since they would both stick to tracing for any intruder that may have hacked into their system. Also, a court order would play as a warning to them that their system has already been compromised with, and, they, therefore, need to straighten things up before their entire system collapses.
Together with that, such a sudden court order compels hotmail. com to be a little bit cautious while giving accounts to individuals. They should accept to take responsibility of any crime that occurs and is linked to their agency. Additionally, a court order might be issued by a superior court to requests both the Hotmail. com and the Time Warner cable to disclose to the law enforcement agencies the subscriber of the account holder from which the anonymous emails were sent from.
However, these two agencies might defy to the order, as per 47 U. S. C. § 551, which disallows them to disclose any information concerning their subscribers, However, they may accept the order depending on the situation and for what purpose the email was used, and, for this case the email was used for fraudulent reasons.
