Hello Naveen,
You should not get too fascinated with ethical hacker as they show in movies. Most of the institutes provide just a basic fancy course under the name of ethical hacking, just to attract students and earn more.
Hacking itself is illegal. No companies hire hackers to steal information, as it would land them in serious legal issues.
I would rather recommend you to go for security specialist professionals. These jobs are highly payable and in high demand as most companies need them to protect their own data.
This requires knowledge of Computer Networking. As you've mentioned that you will be opting for Software Engineering, I would suggest you to opt for Security Specialist course during or after your third year of engineering, as by then, the basics required for Security Specialist course would have been covered in your engineering syllabus.
You can go to some reputed computer training institutes like NIIT, etc. You can go for Java courses followed by networking courses and CCNA/CCNB (CISCO) courses. After this, you can also opt for CEH (Certified Ethical Hacker) certification courses, if you wish to.
I hope it helps.
