An anonymous reader writes "Nearly 80 percent of security products fail to perform as intended when first tested and generally require two or more cycles of testing before achieving certification, according to a new ICSA Labs report that details lessons gleaned from testing thousands of security products over 20 years. Across seven product categories core product functionality accounted for 78 percent of initial test failures. For example, an anti-virus product failing to prevent infection and for firewalls or an IPS product not filtering malicious traffic. Rounding out the top three is the startling finding that 44 percent of security products had inherent security problems. Security testing issues range from vulnerabilities that compromise the confidentiality or integrity of the system to random behavior that affects product availability."
