| Network Security | |
| Networkwide Security Features | ● IEEE 802.1x allows dynamic, port-based security, providing user
authentication. ● IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment
for a specific user regardless of where the user is connected. ● IEEE 802.1x with voice VLAN permits an IP phone to access the
voice VLAN irrespective of the authorized or unauthorized state of
the port. ● IEEE 802.1x and port security are provided to authenticate the
port and manage network access for all MAC addresses, including
that of the client. ● IEEE 802.1x with an ACL assignment allows for specific
identity-based security policies regardless of where the user is
connected. ● IEEE 802.1x with guest VLAN allows guests without 802.1x clients
to have limited network access on the guest VLAN. ● Cisco security VLAN ACLs on all VLANs prevent unauthorized data
flows from being bridged within VLANs. ● Cisco standard and extended IP security router ACLs define
security policies on routed interfaces for control-plane and
data-plane traffic. ● Port-based ACLs for Layer 2 interfaces allow security policies to
be applied on individual switch ports. ● Secure Shell (SSH) Protocol, Kerberos, and Simple Network
Management Protocol Version 3 (SNMPv3) provide network security by
encrypting administrator traffic during Telnet and SNMP sessions.
SSH Protocol, Kerberos, and the cryptographic version of SNMPv3
require a special cryptographic software image because of U.S.
export restrictions. ● Private VLAN Edge provides security and isolation between switch
ports, which helps ensure that users cannot snoop on other users’
traffic. ● Dynamic ARP Inspection helps ensure user integrity by preventing
malicious users from exploiting the insecure nature of the ARP
protocol. ● DHCP Snooping prevents malicious users from spoofing a DHCP
server and sending out bogus addresses. This feature is used by
other primary security features to prevent a number of other
attacks such as ARP poisoning. ● IP source guard prevents a malicious user from spoofing or taking
over another user’s IP address by creating a binding table between
client’s IP and MAC address, port, and VLAN. ● Bidirectional data support on the Switched Port Analyzer (SPAN)
port allows a Cisco Intrusion Detection System (IDS) to take action
when an intruder is detected. ● TACACS+ and RADIUS authentication facilitate centralized control
of the switch and restrict unauthorized users from altering the
configuration. ● MAC address notification allows administrators to be notified of
users added to or removed from the network. ● DHCP Snooping helps administrators with consistent mapping of IP
to MAC addresses. This can be used to prevent attacks that attempt
to poison the DHCP binding database and to rate-limit the amount of
DHCP traffic that enters a switch port. ● Port security secures the access to an access or trunk port based
on MAC address. ● After a specific timeframe, the aging feature removes the MAC
address from the switch to allow another device to connect to the
same port. ● Trusted boundary provides the ability to trust the QoS priority
settings if an IP phone is present and to disable the trust setting
in the event that the IP phone is removed, thereby preventing a
malicious user from overriding prioritization policies in the
network. ● Multilevel security on console access prevents unauthorized users
from altering the switch configuration. ● The user-selectable address-learning mode simplifies
configuration and enhances security. ● Bridge protocol data unit (BPDU) guard shuts down Spanning Tree
PortFast-enabled interfaces when BPDUs are received to avoid
accidental topology loops. ● Spanning Tree Root Guard (STRG) prevents edge devices not in the
network administrator’s control from becoming Spanning Tree
Protocol root nodes. • IGMP filtering provides multicast authentication by filtering out
nonsubscribers and limits the number of concurrent multicast
streams available per port. • Dynamic VLAN assignment is supported through implementation of
VLAN Membership Policy Server client capability to provide
flexibility in assigning ports to VLANs. Dynamic VLAN facilitates
the fast assignment of IP addresses. • Cisco CMS Software security wizards ease the deployment of
security features for restricting user access to a server as well
as to a portion or all of the network. ● 1000 access control entries (ACEs) are supported. |
