|BV||Traffic Filtering Internet Perimeter||Version:||0.1|
|Document type:||Building Block Variant||Owner:|
This Building Block Variant...
|... belongs to Working Area:||Network (NW)|
|... is an implementation of Building Block Type:||Traffic Filtering|
|... is intended for use in Environment:||Webhosting|
Traffic Filtering facility to control traversal of data traffic that originates from the Internet as an outer perimeter defence.
Prohibit unwanted data traffic from the Internet towards the ArchiSurance enterprise network back and forth. Filtering is done by means of checking network packet header characteristics against a list of allowed traffic patterns.
Characteristics & indications of usage
Configuration of this traffic filter should stay relatively simple, as it is the first line of defence.
When designing a facility to implement this function, inclusion of all the following elements is prescribed; either mandatory, optional or explicitly forbidden:
|SNMP version 2||prohibited||SNMP version 2 has known security issues.|
When a facility is designed according to this architectural recipe, it must/will satisfy the following Quality Requirements. This is the responsibility of the infrastructure designer. Note that because of the specified Elements (either the mandatory Elements and any applied optional Elements), some of these Requirements might automatically be satisfied.
