What is Computer Forensics?

Friday, November 20th, 2009

Computers have radically changed the way we live your lives. Everyday living as become easier and technologically advanced decades ago. It has changed the way we work and the way we live in our houses. Children to day are sometimes even more technologically aware than their parents. Mobiles phones have gotten smaller and laptops have gotten slimmer.

With the launch of the Iphone that used the touch screen technology it will only be a matter of time when this idea permeates into other devices and appliances. Unfortunately, technology also makes it easier for criminals to their dirty job. However, computer forensics makes sure that technology is put to lawful use.

Crime and computers

We have seen a lot of Hollywood movies about hackers stealing from financial institutions. We have also seen two parties making their deals through bank transfers with a bunch of computers. Although these are not possible in real life, there are other ways that criminals can use computers.

Computer forensics is basically applying computer science to assist in the legal process. It entails the technological and systematic inspection of the contents of a computer system for evidence. Individuals in this field are called by different titles such as digital media analyst or computer forensics investigator. These people scanned a computer thoroughly to find out if they have used for a civil wrongdoing or criminal act.

The first task of the computer forensic investigator is to find sources of documentary or digital evidence. The next step would be to preserve the evidence so that it could be analyzed later on. When dealing with computer systems, important files or data can be quickly lost.

The investigator should take the necessary test because data retrieval can be time consuming and costly. The investigator would then analyze the collected data for potential and supportive evidence. The final step would be presenting the findings. The investigator will render his opinion based on the examination and make a report.

Computer technology has changed the way we live, work, and for others - commit crime. Although the internet may seem like a very convenient place users should always be wary for seemingly innocent offers.

Computer Forensics - The Case of the Teacher and the Teen Trickster

CSI* - Computer Forensics Files: Real Cases #9 The Case of the Teacher and the Teen Trickster

The stories are true; the names and places have been changed to protect the potentially guilty.

It was a grey October day, the kind of day when a guy likes to cozy up next to a bank of servers to keep warm, when the Teacher first called me. “They think I’m nuts!” were the words emanating from the phone. Well, just because you’re paranoid doesn’t mean they’re not out to get you. I sat up and went to my desk, away from the noisy fans cooling off all those Gigahertzes. “What’s the problem, Miss?”

The young woman explained that she was a not-yet-tenured teacher in a New England (greyer there than here) high school with a problem. Seems that a student in one of her classes was repeating things in the classroom that she had uttered only the night before in the apparently illusory privacy of her own living room. This was happening on a repeated basis and this little freak was freaking her out. She made sure her windows were shut at night. She had someone else speak inside her house while she listened outside - no words escaped to be heard, much less repeated. She looked around for bugs…found only a few spiders. She hired a P.I. to sweep for listening devices - none were found. She went to the police, who were uninterested without some evidence. Her supervisor at the school would not take it seriously. The principal at the school thought she was nuts. She felt that she was in danger of being fired and losing out on a career she’d savored. She was at her wit’s end and sounded it.

She began to suspect her computer was the means of access to invading her privacy, but had no idea how. She already had identified the subject individual and did an admirable amount of research on the subject of computer invasion. She sent me reams of chat logs, articles about cyberinvasions, firewall logs, and other suspicious-looking goings-on with her computer.

I put on my data galoshes and began to wade through the deluge to see what looked like a threat and what did not, and to see if I could find the means of remote access, if any.

Norton Antivirus had picked out some. One was “lsass.shutdown” - the Sasser Worm. A bad character indeed. By contrast, “lsass.exe” is a part of Windows XP itself. Sasser came in looking like something harmless, but in the wider Web, it shut down computers - sometimes before they even finished booting. Airline flights had to be cancelled. Satellite communications were blocked. Insurance companies and banks had to close down for a short while. The Sasser Worm was a bad actor, but it wasn’t giving remote control access and after all, her antivirus program had used its own kind of handcuffs to subdue that particular intruder.

Is a background check expensive? It used to be very expensive. Prior to the internet, people turned to private investigators to find people and research their backgrounds. This took a lot of time and money, even though they were usually thorough searches. Today, online people search services will help you to conduct a search from the privacy and safety of your home or business. The cost is affordable, for as little as a few dollars you can obtain results.

How to fix DLL Errors?

Method 1: a.Click ” Start” menu–”Run”–type in “regedit”. b. Delete these registry keys as below manually:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun

Method 2: Some DLL files would be infected by virus or Trojan. If the anti-virus program on your computer detects and deletes those infected files, you would probably receive error message alarming you that some dll files can not be found. You absolutely will fail to run the relevant applications or programs but keep receiving DLL error message on the startup. In such situation, you have to re-download and install those application to re-register the dll information. So here comes the instruction to disable an application run automatically on system startup in order to avoid such DLL error message:

a. Click ” Start” menu–”Run”–type in “msconfig”—Start— select the certain item to disable.
b. Reboot your computer.

If you feel hard to do this then you can try some registry cleaner programs to disable those startup applications on your computer.

Method 3: DLL Error still could be caused by some uninstalled programs.If you did not uninstall applications completely, the DLL information of it would remain in the system and next time when you start computer the error message of course would appear because system uploads an invalid application. It is highly recommended that you download Registry Easy to clean and diagnose the registry in your system regularly. It will automatically detect and fix invalid and missing registry keys to keep your computer performance running smoothly

Comprehensive Computer Forensics Training

Tuesday, November 3rd, 2009

We live in a world in which computer crimes are common occurrence, and the alarming rates of criminal activity on IT systems has led to a higher demand for experts in the field of computer forensics. If we were to analyze the job growth over the last five years, we’d find no other job with better prospects than computer forensics. This is the factor that has influenced the creation of lots of programs for computer forensics training in education institutions, leading to the appearance of IT specialists that can serve the purposes of the legal system against hackers.

Computer forensics training refers to a wide range of courses that not only teach students how to recover intentionally hidden data, encrypted and deleted files, but also help people understand and cope with the dark side of computers. Illicit activities leave some traces on computer hard discs, and their recovery is a tough process that requires special skills and special forensics tools. Depending on the program, the educational institution and the objective of the courses, the duration of computer forensics training could even take years. There are also some admittance conditions for people eager to become specialists in such applied sciences.

Depending on the level for which the computer forensics training is performed, requirements may differ greatly. While for certain cases, applicants need to have a good understanding of the Windows Operating System, for others, deep knowledge of computer science is necessary. Thus, only applicants with a BA in computer science may be accepted for computer forensics training. Some levels of training are less demanding, and knowledge of security systems and Windows administration experience may be enough. Depending on what course you attend, at graduation you will receive certification and, from case to case, special toolkits as well.

The certification gives you the authority to perform forensics investigations and collaborate to criminal justice cases. Getting computer forensics training could thus help one make a decent living by working with various companies and corporations. In a wider picture, graduates from academic computer forensics training often get jobs in national organizations that cover national data security problems at different levels of intelligence. What needs to be mentioned here is that only the best of the best get in such positions, and the road up there is really paved with challenges and tons of hard work.
