Cyber protection devices

Various cyber protection devices are currently available for use in protecting utility computer systems. These protection devices include anti-virus and pest eradication software, firewalls, and network intrusion hardware/software. These products are discussed in this section. 

It is not the intent of this section to address cyber safety from the view of a network administrator but to make the educator aware of what is needed to make schools cyber environments safe. A school must have both policies and procedures to provide for authentication, firewalls, and virus protection on its computer systems. Authentication will provide secure login and allow individuals to access only the data and applications they require. The firewall also serves as an access control device that will limit user access to unwanted programs and data. Virus protection programs will protect users from viruses and malware on the network. Each of these three areas must be addressed by computing professionals in that environment. The best application for the educator is to teach students the risks associated with the cyber environment and subsequently how to make themselves safe, secure, and ethical cyber citizens. 

IDS. However, single-layer IDSs are more suitable for devices with limited resources as WSN motes. Instead, IDSs belonging the second category (multi-layer IDSs) provide a better protection against cyber-attacks that involve different layers on the other hand, such IDSs require more resources to perform cross-layer data correlations.
