Cards in this deck (14)
- 1FirewallA combination of hardware and software that protects a network from attack by hackers who could gain access through public network, including the Internet
- 2RouterA device that connects two or more networks and allows packets to be transmitted and received between them. A router determines the best path for data packets from source to destination.
- 3SwitchA network device that can replace a router or hub in a local network and get data from a source to a destination. Switching allows for higher speeds.
- 4Web Security GatewayA proxy server with web protection software built-in. Depending on the vendor, the "web protection" can range from a standard virus scanner on incoming packets to monitoring outgoing user traffic for red flags as well.
- 5VPN ConcentratorA hardware device used to create remote access VPNs. The concentrator creates encrypted tunnel sessions between hosts, and many use two-factor authentication for additional security.
- 6Proxy FirewallA proxy server that also acts as a firewall, blocking network access from external networks.
- 7Proxy ServerA type of server that makes a single Internet connection and services requests on behalf of many users.
- 8NIPSNetwork Intrusion Prevention System. An intrusion prevention system that is network based.
- 9NIDSNetwork Intrusion Detection System. An approach to an IDS, it attaches the system to a point in the network where it can monitor and report on all network traffic.
- 10HIDSHost-Based Intrusion Detection System. An intrusion detection system that is host-based. An alternative is an intrusion detection system that is network-based.
- 11Protocol AnalyzerA software and hardware troubleshooting tool that is used to decode protocol information to try to determine the source of a network problem and to establish baselines.
- 12Spam FilterFilters that try to eliminate unwanted, unsolicited email sent in bulk.
- 13WAFWeb Application Firewall. A firewall that can look at every request between a web client and a web server and identify possible attacks.
- 14Examples of Application Aware DevicesFirewalls, IPS, IDS, and Proxies.
