Abstract: There are provided network analyzer and method of analyzing connectivity between a source and a destination. The method comprises: upon obtaining a partial topological network model comprising at least one cloud, generating the one or more paths between the source and the destination, specifying the cloud as a source point of the one or more paths if at least one source network address belongs to the cloud address space and specifying the cloud as a destination point of the one or more paths between the source and the destination if at least one destination network address belongs to the cloud address space. The method further comprises discovering at least one on-path cloud, the method further comprising specifying, by the processor, the at least discovered on-path cloud as a router configured to route the cloud traffic in accordance with predefined rules.

Abstract: There are provided a computer-implemented connectivity manager and a method of managing connectivity between resources in a computer network using the connectivity manager.

Abstract: There are provided a method of automated managing an ordered set of security rules implemented at a plurality of security gateways and a system thereof. The method comprises obtaining data characterizing a connectivity request which may become allowable only upon changes of an initial rule-set, thus giving rise to an unfitting connectivity request; analyzing routing tables of the plurality of the security gateways; generating ranking the security gateways in accordance with their relevance to the unfitting connectivity request; selecting one or more security gateways with the highest ranking; and implementing a configuration change required in order to facilitate allowance of the unfitting connectivity request at the one or more selected security gateways.

Abstract: There are provided a method of automated managing an ordered set of security rules implemented at one or more security gateways and a system thereof. The method comprises a) obtaining data characterizing a connectivity request which may become allowable only upon changes of an initial rule-set, thus giving rise to an unfitting connectivity request; b) automated searching for a rule within said ordered set of security rules, said rule best matching to be amended in order to facilitate allowance of the unfitting connectivity request, wherein best matching is defined in accordance with one or more predefined criteria; c) automated generating amendment of the best matching rule, said amendment capable to facilitate allowance of the unfitting connectivity request; and d) automated implementing the generated amendment at one or more relevant security gateways among said one or more security gateways.

Abstract: The present invention is a method which permits the selective screening for growth-inhibiting substances having a known mechanism of action; i.e., substances which inhibit or otherwise interfere with an enzyme or other gene product whose function is required for the growth or survival of the cell. The method employs cells (e.g., bacterial cells) that contain a nucleic acid fragment that encodes an RNA fragment that can interfere with the expression of a gene product (e.g., an anti-sense RNA that hybridizes to a mRNA), wherein expression of the RNA fragment pre-sensitizes the cell to substances (drugs) that act at the gene product (e.g., a protein or RNA). The cells lose the capability to express the RNA fragment. In the method, the recombinant cells are grown in a nutrient medium in the presence of a test substance under conditions in which expression of the RNA fragment occurs at a level that pre-sensitizes the cell to substances that act at the targeted gene product.
