Cisco is a company that manufactures software used by many people and companies. They have just released three new security updates to patch a number of vulnerabilities in their software that if left unfixed could allow a hacker to take control of your computer and lead to identity theft. As I have repeatedly urged you, it is important to constantly update the computer software you use in all of your electronic devices so as to protect yourself from the latest security threats. Hackers and identity thieves exploit the fact that many people neglect or delay installing security patches.
Here is a link from the United States Computer Emergency Readiness Team to the three security advisories. If you use Cisco software, I urge you to click on these links and download the latest security patches.
