LAB 7: SECURITY BASIC
Task 1:
Hardware firewalls are integrated into the router that sits between a computer and the Internet. They typically use packet filtering, which means they scan packet headers to determine their source, origin, destination addresses and check with the existing user defined rules to make an allow/deny decision.
. Speed: Hardware firewalls are tailored for faster response times, so it can handle more traffic loads.
Security: A firewall with its own operating system is less prone for attacks. This in turn reduces the security risk and in addition, hardware firewalls have enhanced security controls.
No Interference: Since the hardware firewall is an isolated network component, it can be managed better, and does not load or slowdown other applications. The firewall can be moved, shutdown, or reconfigured with minimal interference to the network. Fortinet firewall. It's the most prominent hardware firewall proposed by Gartner technology research group which is widely used for Internet security. The key features of Fortinet hardware firewall are:
Intrusion Prevention System (IPS) - The IPS monitors network activities for malicious or unwanted behavior and can react, in real-time, to block or prevent those activities.
AntiVirus/AntiSpyware/AntiMalware - The advanced Antivirus technology ensures real-time protection against a multitude of attacks at the network gateway.
Support two types VPN (SSL, Ipsec or Site-to-site) with bi-directional content filtering.
Inspects all major protocols like SMTP, POP3, IMAP, FTP, HTTP.
Software firewalls are installed on individual servers. They intercept each connection request and then determine whether the request is valid or not. Software firewall process all requests by using the server resources. Apart from performance limitation, the software firewall has numerous advantages.
While comparing with the hardware firewalls, software firewalls are easier to configure and setup.
