Cisco IOS Networking

Using Cisco's own Packet Tracer, I have accumulated extensive hands-on experience with both Cisco IOS and the best practices of network security and administration. During my Network Security class at Cal Poly Pomona, I demonstrated an advanced understanding of networking principles and earned a 99% total in the class. I have continued to study networking and I plan to obtain my Network+ certification in the near future.

Here are some of the activities i've completed in Packet Tracer

  • AAA Authentication
    In this activity, i set up a network using different standard AAA methods such as TACACS+ and RADIUS. This ensures that users are authenticated to verify their identity, and are only allowed access to specific systems and commands, with the proper authorization. Their actions are also accounted for and logged.
  • Layer 2 VLAN Security
    In this activity, I learned how to set up Layer 2 switches for VLAN security. This included setting up trunking, STP, BDPU guard, portfast, root guard, loop guard, and setting up an ACL for the management VLAN. This allowed for the switches to be secure, reliable, efficient, loop-free, and only controllable from the management VLAN
  • NTP, SSH, and Syslog
    In this activity, I learned how to configure Cisco routers with Syslog, Network Time Protocol, and Secure Shell enabled. This ensures that as a Network Administrator, I am able to monitor and respond to network events as they happen, and securely manage the network remotely.
  • Server Firewalls/Router ACLs
    In this activity, I learned how to set up server firewalls and Access Control Lists (ACLs) for routers. This involved creating ACLs with rules against HTTP and unencrypted web sessions, by disabling port 80. I also set up a firewall on the email server of the main HQ in this activity to block all non-SMTP traffic.
These are just a few examples of my experience in Packet Tracer. I have additionally set up extended ACLs as well as Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS), among other things. These skills culminated in my ability to complete difficult, unguided lab assignments that combined multiple different aspects of network security. With this experience i am confident that I have the skills necessary to excel in Network Administration roles.
