  Automating VLAN Creation on Cisco Devices with Ansible Ansible is a powerful automation tool that simplifies network management tasks, including creating VLANs on Cisco devices. For beginners, this guide will walk you through automating VLAN creation step-by-step, from setting up Ansible to deploying VLAN configurations. What is a VLAN? A VLAN (Virtual Local Area Network) is a logical group of devices within a network that can communicate as if they were on the same physical network, regardless of their physical location. VLANs improve network efficiency and security by segmenting traffic. Why Use Ansible for VLAN Automation? Consistency: Avoid manual configuration errors. Efficiency: Configure multiple devices in seconds. Scalability: Manage large-scale networks easily. Flexibility: Supports various Cisco devices and integrates with other tools. Prerequisites Cisco Device Configuration: Ensure your Cisco devices support SSH and are configured to allow Ans...

  3. Regulatory Compliance: Organizations can enforce application usage policies that align with regulatory requirements, reducing the risk of non-compliance penalties.

  4. Comprehensive Visibility: Gain detailed insights into application usage patterns, enabling better decision-making and fine-tuned control.

Features of FortiGate Application Control

  1. Extensive Application Database: FortiGate supports a robust database of application signatures, covering a wide range of protocols and platforms.

  2. Granular Policy Controls: Administrators can define policies for specific applications, user groups, or devices, providing a tailored approach to network management.

  3. Real-Time Monitoring: The feature includes dashboards and reporting tools that offer real-time insights into application traffic.

  4. Integration with FortiGuard Labs: Continuous updates from FortiGuard Labs ensure the application database remains current, addressing emerging threats effectively.

  5. SSL Inspection: FortiGate Application Control can inspect encrypted traffic, ensuring security without compromising performance.

How to Set Up FortiGate Application Control

  1. Access the FortiGate Web Interface: Log in to the FortiGate web console with administrative privileges.

  2. Enable Application Control: Navigate to the “Security Profiles” section and activate Application Control.

  3. Create or Modify Policies: Define policies that specify allowed or blocked applications. These can be tailored to user roles or specific IP ranges.

  4. Monitor and Optimize: Use the Application Control dashboard to monitor traffic and adjust policies as needed.

Use Cases for FortiGate Application Control

  1. Enterprise Networks: Ensure employees access only approved applications, boosting productivity and reducing risks.

  2. Educational Institutions: Limit access to non-educational applications during class hours, maintaining focus and security.

  3. Healthcare: Protect sensitive patient data by controlling applications that interact with electronic health records.

  4. Retail: Secure point-of-sale systems and prevent unauthorized application usage on the network.

Best Practices for Implementing FortiGate Application Control

  • Regularly Update Policies: Continuously review and update application control policies to adapt to changing network needs.

  • Monitor Traffic Patterns: Use FortiGate’s analytics tools to identify trends and potential threats.

  • Educate Users: Train staff on the importance of adhering to application policies to prevent accidental breaches.

Network Access Control NAC It's something that controls access to the network. And at its simplest level, this is what NAC does.  But if that's all that it was, then it wouldn't be fundamentally different from a network authentication and authorization server. Traditional authentication to the network follows the IEEE 802.1X standard that provided an authentication method to devices wishing to join a Local Area Network (LAN) or wireless LAN. 802.1X Wireless/Wired Authentication The mechanism was a port-based network access control which used agents, the software running on client devices that provide credentials to the authenticator to control access to the network. Another means to control access to a public network such as one serving a coffee shop or in a hotel, is a captive portal. If you've ever connected to a network in an airport, hotel, or coffee shop, you might recall interacting with a web page, sometimes agreeing t...

Issues with CISCO WIRELESS Controller (And resolution) | IT NETWORKS

On Cisco Wireless controller 5520, The Access POINTS try to join the Controller by bringing up a connection through the CAPWAP Tunnel, you can see these attempts through the AP log itself. The problem is that the DHCP server when trying to serve IP Addresses it shows the error BAD_ADDRESS in front of each IP assigned. So I Took a single access point, started debugging it, after that, I noticed that the CAPWAP connection was empty of errors BUT!! it was trying to resolve this name  CISCO-CAPWAP-CONTROLLER This resolution is made with DNS protocol, of course, I honestly wasn't so sure of what I was doing, so I added a new entry in my DNS server and it's corresponding IP was the Controller's after that magically all the Access Points where UP and showed UP on my controller. The controller I'm working with is the CISCO WIRELESS CONTROLLER 5520 Model:  AIR-CT5520-K9 Software Version:  8.3.150.0 Image of the controller Learn...
