P-660HW-Tx v3 User’s Guide 159 C HAPTER 11 Firewalls This chapter gives some back ground information on firewa lls and introduces the ZyXEL Device firewall. 1 1 .1 Firewall Overview Originally , the term firewall referred to a co nstruction tec hnique designed to prevent the spread of fire from one room to another .
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 160 1 1.2.2 Application-level Firewalls Application-level firewalls restrict access by serv ing as proxies for e xternal servers. Since they use programs written for specific Internet servic es, such as HTTP , FTP and telnet, they can evaluate network packets for valid applicatio n-sp ecific data.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 161 1 1.3.1 Denial of Service Att acks Figure 104 Firewall Application 1 1 .4 Denial of Service Denials of Service (DoS) attacks are aimed at devices and networks w ith a connection to the Internet.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 162 1 1.4.2 T ypes of DoS Att a cks There are four types of DoS attacks: 1 Those that exploit bugs in a TCP/IP implementation. 2 Those that exploit weaknesses in the TCP/IP specification. 3 Brute-force attacks that flood a network with useless data.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 163 Figure 106 SYN Flood •I n a LAND Attack , hackers flood SYN packets into the network with a spoofed source IP address of the targeted system .
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 164 1 1.4.2.1 ICMP V ulnerability ICMP is an error -reporting protocol that works in concert with IP . The following ICMP types trigger an alert: 1 1.4.2.2 Illegal Commands (NetBIOS and SMTP) The only legal NetBIOS commands are the following - all others are illegal.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 165 are allowed in. The ZyXEL Device uses stateful packet inspection to protect the private LAN from hackers and vandals on the Internet.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 166 6 Later , an inbound packet reac hes the interface . This packet is part of the connection previously established with the outbound packet. The inbound packet is ev aluated against the inbound access list, and is permitted because of the temporary access list entry previously crea ted.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 167 If an initiation packet originates on the LAN, this means that someone is trying to make a connection from the LAN to the In ternet. Assuming that this is an acceptable part of the security policy (as is the case w ith the default policy), the connection will be allowed.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 168 1 1 .6 Guidelines for Enhancing Security with Y our Firewall • Change the default password via CLI (Co mmand Line Interpreter) or web configurator . • Limit who can telnet into your router . • Don't enable any local service (such as SN MP or NTP) that you don't use.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 169 • Always shred confidential inform ation, particularly about your computer , before throwing it away . Some hackers dig through the trash of companies or indivi duals for information that might help them in an attack.
Chapter 11 Firewalls P-660HW-Tx v3 User’s Guide 170 • T o selectively bloc k/allow inbound or outbound traffic between inside host/networks and outside host/networks. Remember that filters can not distinguish traf fic originating from an inside host or an ou tside host by IP address.
