SPAMING!
Here’s some definitions of Spam control that we all should be aware of:
Spoofable-An electronic spammer can change the words so filters don’t recognize the spam; but humans can detect it.
False Positive- This can be a legitimate email that contains spam words or phrases.
Spoofable- Hashbusters can fool bulk detection systems by making the spam appear dissimilar. This can be defeated be inserting non spam words or wording into the machines to see.
Reactive- writing signatures that require collecting spam.
High Overhead- Adaptive learning systems (bayesian) that are hard to train, teach or maintain.
Emerging- This requires extensive vendor investment in tracking email and web reputation.
With Spam Filtering technology, it’s good to know Who, Where, What and How?
Who is and what do we know about the sender. Where does the message, and if it does contain links, what do we know about where they lead to. What does the message contain and what’s it about. How was the message constructed and why was it constructed in such a manor.
