Abstract: In the advent of surreptitiously inserted or embedded codes on software and hardware for the espionage purposes, the threat faced by developing countries cannot be overemphasized. This research is geared towards understudying importation of cheap, fairly-used (Tokunbo) mobile devices, PCs and other consumer electronics, with a view to ascertaining the effect they have on the cyber hygiene of Nigerian civil servants and in turn, on Nigerian Information system. A survey was used to collect self-reported data on the backdoor awareness level and cyber hygiene practices of civil servant. Collected data is used to test hypothesis that predicts backdoor awareness level has effect on cyber hygiene practices of Nigerian civil servants. ta of general backdoor awareness, while section2 collected data on participants’ cyber hygiene practice. A measurement scale of 1-5 which assumes equidistance is used to assess the participants’ level of backdoor awareness and level of cyber hygiene. This method hides behind existing literature on robustness of statistical methods such as logistic regression, to perform parametric data analysis on interval measurement scale chosen. Categorized data on backdoor awareness and cyber hygiene were subjected to logistic regression. The result showed model to be statistically significant at 0.001 and that the odds of having good cyber hygiene was 2.276 more likely for people with high backdoor awareness than those with low backdoor awareness. Regression weight (B) agrees with the outcome, as a positive regression weight of 0.823 showed that there exists a positive relationship between the independent and dependent variables (Increase in backdoor awareness results in increased cyber hygiene culture. The alternative hypothesis is accepted and Null hypothesis rejected. The researcher recommends: Backdoor awareness campaign among civil servants and ministerial heads, Sensitizing and training organizational heads in information security best practices, National measures to ensure ministerial heads are provided with secure PCs and mobile devices by the organizations they represent, frequent software updates, installing browser security software, anti-keyloggers, anti virus software, together with good cyber hygiene will provide some level of Information system protection.
