Hi everyone, This was interesting to find everyone introducing themselves. It appears that the world of computer security is concerned mostly with UNIX internet servers and firewalls. That seems to me a rather restrictive view of the world. Intruders, according to me, include viruses, unauthorized users, Active contents from the web in PCs and LANs as much as hackers trying to break in by running some password creation program. Intrusion, in real terms is not so much a question of jamming the internet server, but more a question of sanctity and security of information stored in computers.
Encryption plays a great role here both in data storage and in communication.
I would therefore request someone to clear my doubt what is IDS all about.
