Hi. I am MCA(master of computer applications) post graduate from Mumbai University, India. I came across this site while looking for information on ethical hacking.

presently i am working in an small software firm in mumbai. i have been with internet since last 10 years. my entry into hacking was throug pornographic sites. i used view porn sites and then got interested into cracking them using some brutforce softwares and then went into exploiting . but never gone much deeeper due to lack of experiece on linux, unix nand in ethical hacking . after then i've got familier with malwares,phishing,viruses,trojens etc. 

I want explore more in hacking as i already possess knowledge and a certification like in ethical hacking would be an added advantage to my resume. so i want to ask is where can i get the this certificate as i stay in Thane suburb of mumbai,india? Which are the leading, cheaper instittues

I'm with Bill on this, you don't often see someone admit that they got into hacking to look at porn.  Also, I might point you to webster's to make sure you understand the meaning of the word ethical (and no I'm not talking about porn).  Anyone who uses their security knowledge to steal pay-for-use service isn't exactly doing what I'd refer to as "ethical hacking".

Welcome to the community all the same....

Sorry, I'm not familiar with the training centers there. You may want to look into the iClass offered by EC-Council: online training.

Otherwise, I'd suggest looking into the training centers that you do know of there and ask what classes they offer.

Good luck.
