1- What are three risk and threats of the user domain? Top risks are users and social engineering 2- Why do the organizations have acceptable use policies (AUPs)? The AUPs is very important to any organization. The organizations should have AUPs to a- Protect the organizations from any attack weather from inside or outside. The organization can do that by preventing the employees from downloading any services not needed that may be come with threat such as virus or any kind of malware.

TA: Alekhya 6/15/15 The SN2 Reaction: Factors Affecting SN2 Reaction. Introduction In the substitution reactions‚ the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons‚ present on the nucleophile is used to create a new bond with the carbon atom‚ from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1 and SN2. The difference between

1. During the install‚ the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective‚ why is it important for a system to keep accurate time? UNIX systems base their notion of time on interrupts generated by the hardware clock. Delays in processing these interrupts because UNIX systems clocks to lose time slowly but erratically. These small changes in timekeeping are what the time scientist call jitter. The Time protocol provided a server’s notion of time in

Introduction And what is known about the sustainability of current groundwater‚ it is that it will not last. Ponce (2006) states” The unsustainable use of groundwater stands to significantly impact a host of hydrological‚ ecological and other natural resources and services‚ including freshwater bodies‚ and aquatic‚ riparian‚ transitional‚ and ecosystems.” All life on planet earth depends on clean freshwater to survive and It is very important that this natural resource is taken care of properly
