...Hw Lab 1. What is the main difference between a virus and a Trojan? A virus is a program that is capable of replicating with little or no user intervention, and the replicated programs also replicate further. There is typically a piece of code that causes an unexpected, usually malicious, event (payload) to occur. Viruses are often disguised as games or images with clever marketing titles. A Trojan horse is a program that either pretends to have, or is described as having, a set of useful or desirable features, but actually contains a damaging payload. True Trojan horses are not technically viruses, since they do not replicate, however many viruses and worms use Trojan horse tactics to infiltrate a system. Although Trojans are not technically viruses, they can be just as destructive. 2. A virus or malware can impact which of the three tenets of information systems security (CIA)? Describe how it impacts it as well. Virus maybe can send files to other people that don’t allow reading these files. It will affect Confidentiality. Some virus will break program. Then these programs cannot run. This wills effect Availability. Some virus will change some file in a program. This wills effect Integrity. 3. Once a malicious file is found on your computer, what are the default settings for USB/removable device scanning? What should an organization do regarding use of USB hard drives and slots on existing computers and devices? Besides Vendor IDs and Product IDs, some devices...

...Storage Device is susceptible to a virus infection. Yes we do have Antivirus,you have [Insert your best bet AV name],but at some time the virus can and will bypass the security measure that have been placed by our security system software. We also have to remember that the av's rely heavily on its database signature of virus. This means if your system is to be infected by a newly crafted virus ,chances are your av won't detect it at all eventhough its equipped with a highly advanced heuristic scanner. Enough with the bull. What i'm really trying to say is how dangerous it is for us to double click/"Open" your pendrive's drive in "My Computer" right after you plugged in your USB storage device. When you double click or "Open" ,you are actually trying to launch the virus itself embedded in the USB storage device or more specifically you are actually excuting the program stated in the file named autorun.inf.example of the content of the autorun.inf file: [autorun] open=yxcm.exe This is the only way a virus can move,run or to be excecuted. So this method of propagation highly depends if the host has the following.. etc weak av,unupdated av,computer illiterate user. We can safely say that every infected USB storage device have both autorun.inf and atleast an executable. Usually these two files are extra hidden and can only be seen using the Command Prompt. To see the hidden files using the command prompt. Launch the command prompt by clicking the Start button and in the text box...

...Stuxnet Virus According to counterterrorism czar Richard Clarke, Stuxnet was a weaponized malware computer worm. Stuxnet was launched in mid-2009, it did major damage to Iran’s nuclear program in 2010 and then spread to computers all over the world (Clarke, 2012). Type of Breach The Stuxnet is a computer worm, “it is a digital ghost with countless lines of code… it was able to worm its way into Iran’s nuclear fuel enrichment facility in Natanz, Iran” (Clarke, 2012). A worm is a program that spreads copies of itself through a network and a worm can also spread copies of itself as a stand-alone program (Pfleeger & Pfleeger, 2007). How the Breach Occurred On June 17, 2010, Sergey Ulasen, head of a small computer security firm called VirusBlokAda, was going his through e-mail when a report caught his attention. A computer belonging to an Iranian customer was caught in a reboot loop; it was “shutting down and restarting repeatedly despite efforts by operators to take control of it. It appeared the machine was infected with a virus” (Zetter, 2011). Ulasen’s research team got hold of the virus infecting their client’s computers. They realized it was using a “zero-day” exploit to spread (Zetter, 2011). Zero-days are the hacking world’s most potent weapons: The virus exploits vulnerabilities in software that are not yet known to the software maker or antivirus vendors. They’re also exceedingly rare; it takes considerable skill and persistence to find such vulnerabilities and...

...first article it discusses the use of USB devices in the workplace. USB’s are used for transporting data from one computer to another. These allow for business requirements to be reached at a faster pace but they also pose a number of security challenges. Those challenges may be “disgruntled workers, careless users and malicious individuals” (Couture, 2009, p. 6). Ways to migrate this issue is by gluing shut the ports, disable USB ports in BIOS, prevent users from installing a USB device by denying permission on files called usbstor.pnf and usbstor.inf, making USB ports read only, disable USB ports in Group Policy, or disable Autorun (Couture, 2009, p. 11). In the second article it discusses the vulnerabilities of the BIOS. The BIOS performs power up test amongst the hardware components and memory and without this program the computer wouldn’t know what to do after it was turned on. The BIOS can be accessed by the use of backdoor passwords, cracking the BIOS password, deleting the contents of the CMOS RAM by software and/or hardware (Allgeuer, 2001, p. 4). Ways to mitigate the risk of users accessing the BIOS is to use BIOS passwords to protect the BIOA configuration utility, for the more critical systems different BIOS password should be used than less critical systems, boot only from hard drives, computer cases should be...
