Firewalls
<>
 * Firewalls are used to keep a network secure from intruders.
 * Firewalls can be implemented as software only, but for larger businesses, they may also include dedicated hardware for faster processing.
 * Firewalls are widely used to give users secure access to the Internet as well as to separate a company’s public Web server from its internal network.
 * A good firewall will be able to detect Trojans, stop entry by hackers and prevent unauthorised network access.Unfortunately, firewalls are not entirely effective in preventing port scanning.
