Gartner Magic Quadrant for Security Awareness Computer-Based Training (2018,2017,2016,2015,2014) IT research and advisory firm Gartner, Inc. Has evaluated different vendors in the Magic Quadrant for Security Awareness Computer-Based Training (CBT). Gartner’s evaluation criteria includes market understanding, marketing strategy, sales strategy, product strategy and offering, business model, vertical/industry and geographic strategy, and innovation. What is security awareness computer-based training? End-user-focused security education and training is a rapidly growing market.

Basic Setup and Examples. nameif. ciscoasa(config)# interface vlan1 ciscoasa(config-if)# nameif inside INFO: Security level for “inside” set to 100 by default. Unicast IPv4 and IPv6 traffic is allowed through the transparent firewall automatically from a higher security interface to a lower security interface, without an ACL.
Broadcast and multicast traffic can be passed using access rules. The following destination MAC addresses are allowed through the transparent firewall. Any MAC address not on this list is dropped. TRUE broadcast destination MAC address equal to FFFF.FFFF.FFFF. IPv4 multicast MAC addresses from 0100.5E00.0000 to 0100.5EFE.FFFF.
IPv6 multicast MAC addresses from 3333.0000.0000 to 3333.FFFF.FFFF. BPDU multicast address equal to 0100.0CCC.CCCD. AppleTalk multicast MAC addresses from 0900.0700.0000 to 0900.07FF.FFFF The transparent mode ASA does not pass CDP packets packets, or any packets that do not have a valid EtherType greater than or equal to 0x600. An exception is made for BPDUs and IS-IS, which are supported. To prevent loops using the Spanning Tree Protocol, BPDUs are passed by default. To block BPDUs, you need to configure an EtherType ACL to deny them.
If you are using failover, you might want to block BPDUs to prevent the switch port from going into a blocking state when the topology changes. When the ASA runs in transparent mode, the outgoing interface of a packet is determined by performing a MAC address lookup instead of a route lookup. Route lookups, however, are necessary for the following traffic types:. Traffic originating on the ASA. Traffic that is at least one hop away from the ASA with NAT enabled Voice over IP (VoIP) and DNS traffic with inspection enabled, and the endpoint is at least one hop away from the ASA. By default, all ARP packets are allowed through the ASA. You can control the flow of ARP packets by enabling ARP inspection.
Because the ASA is a firewall, if the destination MAC address of a packet is not in the table, the ASA does not flood the original packet on all interfaces as a normal bridge does. Instead, it generates the following packets for directly connected devices or for remote devices:. Packets for directly connected devices—.
Packets for remote devices— Transparent Mode Default Settings – The default mode is routed mode. By default, all ARP packets are allowed through the ASA.
If you enable ARP inspection, the default setting is to flood non-matching packets. The default timeout value for dynamic MAC address table entries is 5 minutes. By default, each interface automatically learns the MAC addresses of entering traffic, and the ASA adds corresponding entries to the MAC address table. Multiple Context Mode. Ciscoasa(config)# mode multiple WARNING: This command will change the behavior of the device WARNING: This command will initiate a Reboot Proceed with change mode? confirm Convert the system configuration?

Inbound and Outbound Rules You can configure access rules based on the direction of traffic:. Inbound—Inbound access rules apply to traffic as it enters an interface. Global and management access rules are always inbound. Outbound—Outbound rules apply to traffic as it exits an interface. “Inbound” and “outbound” refer to the application of an ACL on an interface, either to traffic entering the ASA on an interface or traffic exiting the ASA on an interface.
These terms do not refer to the movement of traffic from a lower security interface to a higher security interface, commonly known as inbound, or from a higher to lower interface, commonly known as outbound. Note An outbound ACL is useful, for example, if you want to allow only certain hosts on the inside networks to access a web server on the outside network. Rather than creating multiple inbound ACLs to restrict access,. access-list (ACLs). Traffic going from a lower security interface is denied when going to a higher security interface. Traffic going from a higher security interface is allowed when going to a lower security interface.
