Identity Management
Identity Management is concerned with the life cycle of the identity of subjects and objects and by default being able to prove this identity as and when required.
There's nothing new about this concept and arguably is the basis of a community of which these entities are members.
Each entity must have a reference characteristic that is unique within the community to which they belong. It could be anything from a simple name to an 80 digit number which would be enough to identify every atom in the universe.
Originally individuals only ever existed in their own environmental community, a tribe of perhaps 100 people, where everyone knew everybody else. Over time this expanded to the use of intermediaries for vouching identity, an employer or a banker's reference for example. Of course in some cases this identity has to be established from scratch, when you move area for example.
But in all cases what is clear is that the identity only makes sense in terms of the relationship between the two entities. The only difference is about how quickly you establish the trust that underlies a relationship. In the electronic world these concepts have morphed into two approaches;
The eBay model, where you start from scratch and build up a reputation (under your eBay ID) that both parties (buyer and seller) to a relationship can freely observe.
The reference model, where some third party vouches for your identity. We tend immediately to think of Certification Authorities and Digital Certificates but in actual fact our credit card is a form of reference ID. The bank takes on the role of vouching for our identity in a totally foreign community and providing the necessary (in this case) commitment to pay.
It is clear that this reference model approach is dependent on an adequate level of security from the supporting cryptographic infrastructure and identity tokens. It also has to take account of social engineering such as phishing and pharming. This is our work space, please contact us with your requirements.

Intrusion Detection Systems
Anderson (1980) he hypothesised that legitimate usage of computer systems follows a characteristic pattern which can be identified by extracting usage information from audit trails. Similarly, he maintained that since the 'normal' behaviour could be quantified, it should be possible to expose attacks as these would manifest themselves as irregularities in the known pattern - i.e. 'abnormal' behaviour. According to Anderson (1980), these irregularities may include the following: "a) use outside normal time b) abnormal frequency of use c) abnormal volume of data reference d) abnormal patterns of reference to programs or data."
"An IDS is a security system that monitors computer systems and network traffic and analyzes that traffic for possible hostile attacks originating from outside the organization and also for system misuse or attacks originating from inside the organization."
