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.

Hello Vishal,
While CSE, equally covers both hardware and software aspects. IT and software engineering has a lesser focus on the hardware aspect. However, this difference hardly matters as universities frequently keep updating the syllabus for each branch.
Unless and until, you get a job in a hardware manufacturing company like Intel, Logitech, etc., this little difference in the syllabus hardly matters. Most of the jobs offered is in the software domain.
There is no need to compare the little differences between the branches. You can get admission in a decent college in any of these branches. You should keep a percentage of over 70 without any backlogs and have a great start for your future.
All the best.
