Loopholes in Services-I
After a long journey, I come to my favourite part of security analysis. Today onwards, I am going to cover security loopholes in various Internet services and protocols.

So here we are going to study, one-by-one, different Internet services which you use daily (some knowingly, some unknowingly) and then see the security risks involved in each of them.

Types of Attackers
This section very briefly describes the types of attackers who are out there on the Internet. There are many ways to categorize these attackers; we can't really do justice to the many variants of attackers we've seen over the years, and any quick summary of this kind necessarily presents a rather stereotyped view. Nevertheless, this summary may be useful in distinguishing the main categories of attackers.

Types of Attacks
I enter a new phase of discussion. If you have been following me, you already have been through viruses, trojans, password crackers, port scanners, IP sniffers, IP spoofers, etc. So I can safely assume that you have updated your knowledge about Internet security. Today onwards, we look into the types of attacks possible on your network or web server. We try to classify them in order of severity. The type of attack depends on the attacker. It is imperative to know the attacker. So we also try to classify the attackers.

WEB & HTTP
The Hypertext Transfer Protocol (HTTP) is an application-level protocol developed for distributed, collaborative, hypermedia information systems. The HTTP protocol is very generic and stateless, allowing systems to be built independently of the data being transmitted. We are not going to see the working of this protocol. That will take ages.
