This is especially true with vendors default community. Numerous vulnerabilities exist with SNMP therefore, without unique SNMP community names, the risk of compromise is dramatically increased. The network device must use different SNMP community names or groups for various levels of read and write access. Since NTP is used to ensure accurate log file time stamp information, NTP could pose a security risk if a malicious user were able to falsify NTP information. Network devices must authenticate all NTP messages received from NTP servers and peers. Management connections to a network device must be established using secure protocols with FIPS 140-2 validated cryptographic modules.Īdministration and management connections performed across a network are inherently dangerous because anyone with a packet sniffer and access to the right LAN segment can acquire the network. In addition, these services provide an unsecured method for an. The additional services the router is enabled for increases the risk for an attack since the router will listen for these services. The network element must have HTTP service for administrative access disabled. Without the strong authentication and privacy that is provided by the SNMP Version 3 User-based Security Model (USM), an unauthorized user can gain. SNMP Versions 1 and 2 are not considered secure. The network device must use SNMP Version 3 Security Model with FIPS 140-2 validated cryptography for any SNMP agent configured on the device.

Network devices with no password for administrative access via a management connection provide the opportunity for anyone with network access to the device to make configuration changes enabling. The network devices must require authentication prior to establishing a management connection for administrative access. Network devices may be distributed by the vendor pre-configured with an SNMP agent using the well-known SNMP community strings public for read only and private for read and write authorization. The network device must not use the default or well-known SNMP community strings public and private.

Network devices not protected with strong password schemes provide the opportunity for anyone to crack the password thus gaining access to the device and causing network outage or denial of. Network devices must not have any default manufacturer passwords. Hence, it is imperative that all passwords are encrypted so they cannot be intercepted by viewing the. Many attacks information systems and network elements are launched from within the network. The network element must be configured to ensure passwords are not viewable when displaying configuration information. Access to the network must be categorized as administrator, user. Network access control mechanisms interoperate to prevent unauthorized access and to enforce the organization's security policy. Network devices must be password protected.

It is to be used only when the authentication server is offline or not reachable via the. The emergency administration account is to be configured as a local account on the network devices. The emergency administration account must be set to an appropriate authorization level to perform necessary administrative functions when the authentication server is not online. If group accounts are not changed when someone leaves. Group accounts configured for use on a network device do not allow for accountability or repudiation of individuals using the shared account. Group accounts must not be configured for use on the network device. The IEEE 802.1x standard is a client-server based access control and authentication protocol that restricts unauthorized clients from connecting to a local area network through host facing switch.
The switch must be configured to use 802.1x authentication on host facing access switch ports. Network devices with no password for administrative access via the console provide the opportunity for anyone with physical access to the device to make configuration changes enabling them to. The network device must require authentication for console access. Findings (MAC III - Administrative Sensitive) Finding ID
