    Study Notes

    Cisco Device Configuration and Security Basics

    • The banner motd command is used to configure a message of the day (MOTD) with a termination character specified after the message.
    • Passwords are fundamental security mechanisms, including console/line passwords and enable-mode passwords, which restrict access to critical configurations for network administrators.
    • Console/Line access allows limited user-level commands, such as viewing configuration and system status information.
    • Malicious access to the running-config can reveal critical infrastructure information, potentially leading to follow-up attacks.
    • Cisco device passwords are stored as plaintext in configuration files by default, but the enable secret password is encrypted using MD5.
    • Password encryption must be enabled through the service password-encryption command to prevent users from viewing plaintext passwords in configuration files.
    • The 7 or 5 prefix in passwords indicates the level of encryption, with 7 representing Vigenere encryption and 5 representing MD5 hashing.
    • The service password-encryption command converts plaintext passwords to type 7 (Vigenere) encryption, but cannot force type 5 (MD5) encryption.
    • Vigenere encryption is vulnerable due to its age, well-known key, and trivial decryption with modern technology.
    • Console configurations secure the physical connection and require setting a password and enabling the login process for user authentication.
    • Enable-mode passwords can be set as plaintext with optional Vigenere encryption or as MD5-based passwords using the enable password and enable secret commands.
    • Remote management of Cisco devices is primarily done through the Virtual Terminal Lines (VTY) using Telnet, SSH, and RADIUS for authentication and access.

    Network Monitoring and Backup Protocols

    • Syslog is a standardized system for messaging that logs events such as port-security violations and configuration changes.
    • Syslog has configurable 'trap' levels from 0 to 7, each corresponding to different types of events.
    • The setup of Syslog involves the use of a Syslog server and network connectivity to the server.
    • SNMP (Simple Network Management Protocol) allows for active monitoring and metric collection of devices, and it enables configuration changes remotely.
    • TFTP (Trivial File Transfer Protocol) is a simple and easy-to-use service for writing and reading files from a centralized location.
    • TFTP has no authentication, making it vulnerable to unauthorized access, and it requires port 69 to be open.
    • The process for using TFTP to backup configuration involves copying the startup-config to a designated TFTP server location.
    • Restoring using TFTP involves copying the startup-config from the designated TFTP server location to the device.
    • TFTP prerequisites include having port 69 open and a TFTP server installed, and ensuring connectivity from the device to the TFTP server.
    • Newer technologies like FTP and SCP are available as alternatives to TFTP and are supported by most newer Cisco protocols.
    • Setting up TFTP involves installing Solarwinds TFTP software on the laptop and ensuring it is ready for use.
    • It is recommended to install and try the Kiwi Syslog and Solarwinds TFTP software for testing and future assignments.

    Configuring Role-Based Access Control (RBAC) and Port Security in Cisco Switches

    • RBAC allows creation of custom roles with specific privileges, assigned to users
    • Custom roles are created using the "privilege exec level" command, specifying allowed commands
    • Users are assigned to roles with specific privileges and passwords
    • RBAC in Cisco switches and routers can be complex due to granularity and requirements
    • Port security restricts access based on criteria such as connected devices and MAC addresses
    • Port security violations can be set to protect, restrict, or shutdown modes
    • Dealing with violations depends on the type, with "protect" and "restrict" requiring manual reset
    • "Shutdown" violations halt port operation and require a reset of the port
    • Violations can be found by checking syslog server notifications or using specific show commands
    • Port security counters can only be reset by disabling and re-enabling port security
    • Enabling port security involves several steps, including selecting the interface and enabling port security
    • Configuring port security includes setting maximum allowed MAC addresses, violation type, aging time, and sticky MAC addresses. Unused ports should be shut down for security.
