"The LPI has been working on this security
certification option since March 2008. To obtain this
certification, roughly equivalent to the RHCE (Red Hat Certified
Engineer) or the NCLE (Novell Certified Linux Engineer), a Linux
administrator must have already obtained the LPIC-1 and LPIC-2
certifications. In addition, he or she must pass the
enterprise-level core certification exam (LPI-301) and a 'Mixed
Environment' elective (LPI-302). The 'Security' elective (LPI-303)
is another, potentially valuable mixed Linux and security
certification option."
