Essential data - Essay Example annual sales of SVL 12†, 15† and 19† flat screens of computers, the chart shows that the annual sale of Type C screens that are 19† are greater than sales of type B and type a it is obviously because the 19† screens are expensive than 12† and 15†. The correlation is one of the most common and most useful statistics. A correlation r is a single value that explains the degree of relationship among two variables. Correlation value r will always be between -1.0 and +1.0, if the correlation is negative, we have a negative relationship; if its positive, the relationship is positive. Here we have the correlation value r = -0.786 and the scatter plot shows a negative association between distance of SVL outlet and the Total sales in SVL outlets, it means the sales in SVL outlets that are near to high streets is more than in those outlets that are far from the high street. The correlation value r = 0.772 and the scatter plot shows a positive association between average monthly advertising expenditure and the Total sales in SVL outlets, it means the sales in SVL outlets increases with the expenditure on advertising. Regression investigates the dependence of one variable conventionally called the dependent variable on one or more variables called independent variable and provide an equation to be used for estimating or predicting the average value of the dependent variable from the known values of independent variable. Where, Y is the predictor, X is the predictor, â€Å"a† is the value of Y when X equals zero and is called Y-intercept, and â€Å"b† indicates the changes in Y for a unit change in X and is called the slope of the line and â€Å"e† is an error term having a normal distribution with mean of zero and standard deviation ÏÆ' (Fisher, 1922). We estimate â€Å"a† by â€Å"a†, â€Å"b† by â€Å"b† and â€Å"ÏÆ'† by â€Å"s†. The fitted equation is then: If we have P-value < ï  ¡ then we have to reject our hypothesis, from ANOVA table of regional location and

Security Analysis and Redesign of a Network Essay

Security Analysis and Redesign of a Network - Essay Example Service Information: Operating System: Linux 2.5.25 - 2.6.3 or Gentoo 1.2 Linux 2.4.19 rc1-rc7. Interesting ports on XYZ Invite Design at domain 192.168.0.6: Nmap done: 6 IP address (6 hosts up) scanned in 64.27 seconds. Password strengths are essential in security matters. Users’ password must be encrypted so as to prevent unauthorized entries to the system (Stewart, 2010). The Public Key Infrastructure, Hashing and Digital Signatures, Cryptography: Public Key Encryption and Cryptology assist in the implementation of password protection. Set up an NTFS drive applicable for the IIS application and data. If likely, do not tolerate IUSER or whatever the unidentified username access to any of the available drives. If the relevance runs into any problems due the anonymous user does not have admission to programs on the available drive(s), then apply FileMon from Sysinternals to test which file it cannot access and attempt working around it by relocating the program to the IIS drive. If that is not possible, then permit IUSER access just to that file. Allow Windows auditing on the machine, since there is never sufficient data when trying to backtrack any attackers movements. It is even likely to have a script run to check for any distrustful activity via the audit logs, and then send an account to an administrator. Now this could appear a bit extreme, but if security is actually significant in your organization, this sort of action is an excellent practice. Set up auditing to account any failed account log in attempts. Plus, same as the IIS logs, alter the default location to a different location, and make sure that the company have a backing and a replicated copy (Weaver, Weaver, & Farwood, 2013). On a customary basis, go through as a lot of security articles from various sources as the company can. It is at all times better that company appreciate as much as possible about IIS and universal
