Network security is everyone's concern, and this applies to computer security as well. Many security breaches occur due to user ignorance of basic security principles, not malicious intent. Network and computer security are like an onion - there are multiple layers. Good security begins with understanding what you can do to keep your systems safe and implementing a layered approach. If you depend on one program or feature to secure your computer, then when (not if, but when) that dependency is breached, you may have personal information stolen or even have your computer taken over.

Security attacks have become more advanced; therefore, security solutions have needed to evolve to deal with those threats. Cisco's acquisition of Sourcefire brings a new paradigm to the security landscape. No longer is security a one-time, instantaneous event. Security now is threat based, network cognizant, and continuous. All organizations, public and private, need to be aware not only of the constantly changing threat environment, but must be prepared to respond in kind.

The responsibility for securing organizational data has spread beyond the traditional IT professional. While there are more diverse security solutions, there are more diverse and sophisticated security threats. Security awareness and training is essential for everyone within an organization. Learn how Cisco has continued to evolve its security solutions and training.
