Network Security and Management
Network security refers to any activities designed to protect your network. Specifically, these activities protect the usability, reliability, integrity, and safety of your network and data. Effective network security targets a variety of threats and stops them from entering or spreading on your network.
Many network security threats today are spread over the Internet. The most common include:
Viruses, worms, and Trojan horses
Spyware and adware
Zero-day attacks, also called zero-hour attacks
Denial of service attacks
Data interception and theft
Network security is accomplished through hardware and software. The software must be constantly updated and managed to protect you from emerging threats.
