Intrusion Detection System Intrusion detection is the security industry term for detecting unauthorized use of your network. Unauthorized use might be from outside attackers, users who misuse their privileges, or users trying get to restricted info. It merely detects it. An IDS will let you know that an intrusion has taken place, that someone has had unauthorized access to your data. You will then be able to track what data was compromised and begin recovery efforts.
Many organizations mistakenly believe that no one is interested in their data.
Unfortunately, no organization, not even Microsoft, is immune from attacks. Therefore, electronic signatures are optional. In the current state of technology, digital signatures are considered the only technique capable of nonrepudiation and are therefore the only acceptable electronic signature. SSL is the leading security protocol on the Internet. SSL uses digital certificates to authenticate the server, so the client knows who it's talking to.
