There is a significant shortage of network security professionals, with many job positions unfilled annually due to the lack of qualified applicants. Earning recognized certifications can greatly enhance one's qualifications for these roles. Various organizations offer certifications, including GIAC, (ISC)², ISACA, EC-Council, and CWSP. Cisco has updated its certification structure, replacing the CCNA Security with the CCNP Security, which requires passing a security core exam and one concentration exam.
