Networking giant Cisco has published a raft of security advisories as part of its biannual patch-release schedule.
Cisco and the security community are debating the reality of rootkits attacking the Cisco's Internetwork Operating System (IOS) after a researcher presented a proof of concept attack, which threatens Cisco routers and voice over IP phones.
Companies are refusing to update their router operating systems even though they contain known vulnerabilities, leaving their network full of security holes, according to Cisco's top security exec.
The intrusion prevention capabilities of Cisco Systems' routers could be prone to attack, after the networking giant revealed two vulnerabilities in its key operating system.
Three security holes in the software that runs Cisco Systems' routers and switches could let miscreants disrupt computer networks, including the Internet.
If you ran a software company and an independent security researcher contacted you with proof that your product contains security vulnerabilities, how would you react?
Cisco is preparing to announce a major overhaul of its security portfolio next week, with upgrades to several of its existing products.
