Cisco has launched an internal code review following Juniper’s disclosure of unauthorized spying code in firewall products. Juniper said last week an internal audit uncovered code that could allow secret remote access and also compromise encrypted VPN connections. The code was found in some versions of an operating system called ScreenOS that powers firewall devices. The problem is the latest in a string of issues that have affected major networking vendors, whose routers and firewalls have deep access to an organization’s Internet traffic. The devices are pivotal points to launch spying campaigns.”]
