Ping Sweeps and Port Scans January 11‚ 2013 Freddie Jackson DeVry University This report is to provide insight on nefarious computer activities called ping sweeps and port scans as a request from management. I will identify them‚ explain what they are use for‚ how they are used and how to stop them from attacking a network. Finally I will discuss how they can be eliminated as security risk. The information in this report is designed to increase the understanding and knowledge of these two

The PET scan‚ or Positron Emission Tomography‚ was born in 1973 at Washington University. It was created by Edward Hoffman‚ Michael M. Ter-Pogossian‚ and Michael E. Phelps; Phelps is most often credited with the invention (History of PET and MRI‚ 2009). In preparation for a PET scan‚ radioactive tracers are injected into the body‚ inhaled‚ or ingested by the patient through a solution that they drink. Then the scan will actually begin‚ as the patient lies on a table‚ which glides into the machine

SEC280 March 10‚2011 Ping Sweeps and Port Scans: Should we worry? Ping Sweeps and Port Scans are the two most common network probes that serve as important clues in sensing invasion or intrusion that can harm a network. Network probes are not actual intrusions‚ although‚ they could be potential causes of actual intrusions. Port scans and ping sweeps can lead to an intrusion of companies network system‚ however‚ with today’s technological advancements‚ these activities can be detected

Imagine being able to detect diseases in your body‚ or being able to examine various tissues and determine its conditions. That is exactly what an positron emission tomography (PET) scan is used for. Unlike CT (computed tomography) and MRI (magnetic resonance imaging) scans‚ the PET scan can reveal the cellular level changes occurring in an organ or tissue. To obtain this information‚ a very small dose of a radioactive chemical‚ called a radiotracer‚ is injected into the vein of the patient’s arm

(Magnetic Resonance Imaging) and CAT scans are used by doctors daily. However there are some differences such as CAT scans uses radiation meanwhile MRI doesn’t. Another difference is that MRI is a closed tube meanwhile CAT scan isn’t closed and has lots of space. Both MRI and CAT scans have pros and cons. A CAT scan is an x-ray image made by using radiation and MRI is the use of magnetic field and radio waves to create images of our body. One pro for CAT scans is that it detects diseases before it

Ping sweeps and Port scans are a great security tool for businesses. Ping sweeps are used to find someone on the end of a network and Port scans are then used to find a way into that end of the network. Once a perpetrator gets in there is no telling what harm could be done. These techniques can also be used for troubleshooting issues that can arise inside the company. It is in the company’s best interest to be aware of ping sweeps and port scans to help from devastating consequences later on. A
