1. A method of automated managing one or more security rule-sets, the method comprising: a. obtaining data characterizing a connectivity request and data characterizing an amended rule-set, the amended rule-set being derivative of an initial rule-set amended to fit the connectivity request; b. automated verifying each possible combination of values in the connectivity request against the initial rule-set and the amended rule-set; c. calculating one or more values selected from a group comprising values characterizing relative amount of extra allowed traffic and values characterizing relative amount of dissatisfied requested traffic; d. automated comparing the calculated values and/or derivatives thereof with a predefined threshold; and e. automated classifying the amended rule-set as applicable for implementation if the results of the automated comparing match a predefined verification criterion.
