Which of the following can provide some protection for your network from outside invaders? (Choose three)
|
Firewalls
- Proxy Servers - Packet-Filtering Routers Explanation: A firewall can greatly improve network security and reduce risks to hosts \non the subnet by filtering inherently insecure services. As a result, the subnet network environment is exposed to fewer risks, since only selected protocols will be able to pass through the firewall. A firewall also provides the ability to control access to site systems. For example, some hosts can be made reachable from outside networks, whereas others can be effectively sealed off from unwanted access. Privacy is of great concern to certain sites, since what would normally be considered innocuous information might actually contain clues that would be useful to an attacker. Using a firewall, some sites wish to block services such as finger and Domain Name Service. If all access to and from the Internet passes through a firewall, the firewall can log accesses and provide valuable statistics about network usage. A firewall, with appropriate alarms that sound when suspicious activity occurs can also provide details on whether the firewall and network are being probed or attacked. |
