Cisco's customers are not accustomed to regularly updating the operating system on their network hardware, which has left many of them with a 'hygiene' problem when it comes to security, according to Cisco's chief security officer John Stewart.
A serious flaw in Cisco software puts computer networks at risk of cyberattack and has prompted security vendor Symantec to raise its Internet threat level.
Flaws in Cisco Systems software for routers and IP telephony could be a conduit for attacks on enterprise networks, the company has warned.
Multiple vulnerabilities found in a VPN protocol used by most router vendors means that administrators are once again being advised to patch their network hardware, which is a far bigger issue than patching servers or desktops.
Cisco Systems has patched a flaw in the software used to run its routers and switches, a new twist in the company's dispute with a security researcher that has roiled the security community.
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?
Security researcher Christopher Soghoian reflects on the hard work that comes after finding a vulnerability.
Although many software makers promote responsible disclosure, it isn't universally backed by the security community. Critics say it could make security companies lazy in patching. Full disclosure of flaws is preferred.
