There are 2 parts on <a href="https" rel="ugc">https</a>: <br />
1. certificates: a certificate proves to you that the site that you are talking to is actually the site that you would like to talk to. You can actually view the certificate by clicking on the padlock sign of a Internet browser when you access a https site. You will see which authority provided the certificate (these authority actually do check out the companies they give the certificates too) and the details of the company who's website you are accessing.<br />
2. encryption: the communications over https are encrypted and each session will get it's own decryption key. For someone to crack a 128 or 256 bit encrypted message many many samples are needed. Because the keys change with each session, https is virtually not crackable.<br />

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
