Because network forensics can be performed for many purposes with dozens of data source types, analysts may use several different tools on a regular basis, each well-suited to certain situations. Analysts should be aware of the possible approaches to examining and analyzing network traffic data and should select the best tools for each case, rather than applying the same tool to every situation. Analysts should also be mindful of the shortcomings of tools; for example, a particular protocol analyzer might not be able to translate a certain protocol or handle unexpected protocol data (illegal data field value). It can be helpful to have an alternate tool available that might not have the same deficiency.
