Is there a bright future in the field of Network Security ?? if yes then .... in which kind of skills a person must be proficient ???
Do you mean "career" instead of carrier? If so I recommend the following Yahoo group for CISSP jobs. http://tech.groups.yahoo.com/group/CISSPjobsforum/ These are real job leads all over the world. But the skills you need would be practical experience through your job role or from consulting, certifications from SANS and CompTIA and other vendor-specific certs would help, and I would recommend attending conferences to learn new things and stay updated with the changes in technology.
