Security Policy The PIX Firewall separates the details of implementing a security policy from providing network services such as Web, FTP, Telnet, and SMTP A security policy provides: o Much better scalability and performance The PIX Firewall is dedicated to the security role and does not incur the substantial overhead required to offer server connections o Greater security Unless configured to do so, the PIX Firewall does not accept connections from the outside network and is implemented using a proprietary embedded system, rather than the full operating system necessary to support server applications o Reduced complexity Each device performs a dedicated function.

Making Image Backups You should back up your configuration to both Flash memory and diskette after making changes to the configuration Use the write memory command to store your configuration in Flash memory You can enter this command from configuration mode Flash memory is a special type of memory card that stores images without the need for a battery or power source to maintain the image Use the write floppy command to store the configuration on diskette Each image you store overwrites the last stored image in either Flash memory or diskette Should the need arise, you can restore your configuration from Flash memory with the configure memory command, or from diskette with the configure floppy command.

Default configuration commands nameif Identifies the interface name and specifies its security level. If you have more than two interfaces, you need to add a nameif command to the configuration for each interface Lists the encrypted privileged mode password Lists the encrypted password for Telnet access to the PIX Firewall console Sets the PIX Firewall system name to "pixfirewall.

The packet is forwarded to the protected interface The PIX Firewall permits all outbound connections from the protected networks to the unprotected networks, and rejects any connections inbound from the unprotected network PIX Firewall Connections Maximum number of connections you can have on your PIX Firewall Installed RAM 16 MB 32 MB MB Maximum Number of Connections 32, connections 65, connections Approx , connections with the optional memory upgrade Access Lists Can control which inside systems can establish connections to the outside network The default security policy can be modified to be consistent with the site security policy by limiting outgoing connections based on inside source address, outside destination address, or protocol Configure access lists carefully if your security policy limits outgoing connections Visit Examnotes.

Actively randomizes TCP sequence numbers to minimize the risk of TCP sequence number attack Conduits Conduits allows connections from the outside network to the inside network For some applications or business requirements, it is desirable to establish connections to the inside or perimeter networks Each conduit is a potential hole through the PIX Firewall and their use should be limited as your security policy and business needs may require Make conduits as specific as possible Be aware that as the PIX grows up the conduit command will be replaced by IOS features like access lists.

You need to set up specific cabling to provide this failover as well Java Filtering Lets an administrator prevent Java applets from being downloaded by an inside system This is kind of the same as ActiveX Blocking except ActiveX is pretty specific to Microsoft technologies Java applets are executable programs and can provide a vehicle through which an inside system can be invaded.

Interfaces with the same security level: If you set the perimeter interfaces to the same security level, the two interfaces are completely isolated from each other, but each could access the inside and outside interfaces Locate servers on the lowest security level perimeter interface, because if compromised, the attacker could only easily attack an interface with a lower security level, the outside The only exception to putting servers on the lowest perimeter interface is the TFTP server where you download configurations from the TFTP server must be on the inside interface Telnet: Access to the console via Telnet is available on the inside and third interfaces.
