Hello everyone in this video i will configure traffic shaping and session limit for my test web server , By enforcing session limits, you can prevent a single client or a group of clients from establishing an excessive number of connections, thus reducing the impact of DDoS attacks, also Web servers have finite resources, including CPU, memory, and network bandwidth.
Allowing too many concurrent sessions can lead to resource exhaustion, resulting in degraded performance or even server crashes. The FortiGate Traffic Shaper is a feature within the Fortinet FortiGate firewall platform that allows you to control and manage network traffic by applying quality of service (QoS) policies. The Traffic Shaper provides a set of tools to shape, control, and monitor network traffic based on predefined policies and rules.
1. Log into the FortiGate Web Interface:
Open a web browser and enter the IP address of your FortiGate device.
Log in with administrator credentials.
2. Navigate to Security Policies:
In the FortiGate web interface, go to “Policy & Objects” or a similar section, depending on your FortiGate’s firmware version.
3. Create or Edit a Security Policy:
You can either create a new security policy or edit an existing one. A security policy defines the rules for traffic passing through the firewall.
4. Configure the Session Limits:
a. General Settings: – In the security policy configuration, you’ll find an option to set session limits. Look for a section labeled “Session Options” or similar.
b. Select Session Limit Type: – Choose the appropriate session limit type based on your requirements: – Limit: Sets a maximum limit on the total number of concurrent sessions allowed for this policy. – Per-User Limit: Sets a session limit per user, which is useful in user-based authentication scenarios. – Per-IP Limit: Sets a session limit per source IP address.
c. Configure Limit Value: – Specify the numeric value for the session limit. For example, if you chose “Limit” and set the value to 100, this policy would allow a maximum of 100 concurrent sessions.
d. Define Action on Limit: – Choose what should happen when the session limit is reached. Common actions include: – Accept: Continue accepting new sessions, ignoring the limit. – Drop: Reject new sessions once the limit is reached. – Log: Log information about sessions that exceed the limit. – Rate Limit: Throttle the rate of new sessions when the limit is reached.
e. Idle Timeout and Session Timeout: – These settings help manage session duration: – Idle Timeout: Set the maximum time a session can remain idle (no traffic) before it’s terminated. This prevents stale connections from consuming resources. – Session Timeout: Define the maximum duration a session can last before being terminated, regardless of activity.
f. Advanced Session Options (Optional): – Depending on your FortiGate firmware version and specific requirements, you may have additional session-related options to configure. These could include session helpers for specific protocols or advanced settings for more granular control over session behavior.
5. Save and Apply the Configuration:
Once you’ve configured the session limits according to your requirements, save the changes and apply the updated security policy.
6. Testing and Monitoring:
Thoroughly test your firewall rules and session limits to ensure they align with your network’s security and performance needs.
Monitor firewall logs and session statistics to track how the session limits are being enforced and whether any adjustments are needed.
Please note that the exact steps and terminology may vary depending on your FortiGate firmware version. Consult the official Fortinet documentation or seek assistance from Fortinet support for version-specific details or advanced configurations. Additionally, it’s important to regularly review and update your security policies to adapt to changing network requirements and threats.
Hello everyone , in this video I will integrate my fortigate firewall with windows active directory , by doing this I can write the policies based on logged on users to their desktops , for example for one security group I can write a policy that can be access to facebook and for another group facebook will be blocked , or allow internet just for specific users that raised in security. Writing policies is depend on your environment.
1. Understanding Active Directory:
Active Directory is a Microsoft directory service that stores information about objects on a network, such as users, computers, groups, and more.
It provides centralized authentication and authorization services for network resources.
2. Purpose of Integration:
Integrating FortiGate with Active Directory helps streamline user authentication and access control for network resources.
It simplifies user management by allowing administrators to use AD user accounts for firewall policies.
3. Steps for FortiGate Active Directory Integration:
a. Configuration in Active Directory: – Ensure your Active Directory is properly configured with user accounts, groups, and organizational units (OUs).
b. FortiGate Web Interface Access: – Access the FortiGate web interface using a web browser.
c. Create a New LDAP Server Object: – Navigate to the “System” menu and select “Authentication” > “LDAP Servers.” – Click “Create New” to add a new LDAP server object. – Configure the LDAP server settings, including the server’s IP address or hostname, port (typically 389 for LDAP, 636 for LDAPS), and authentication credentials (usually a service account in AD).
d. Test LDAP Server Connectivity: – After configuring the LDAP server object, you can test the connectivity to ensure FortiGate can communicate with your AD server.
e. Create LDAP Authentication Group: – Go to “User & Device” > “User Definition” > “LDAP Servers.” – Create an LDAP authentication group and specify the LDAP server you created earlier.
f. Define Firewall Policies: – Create firewall policies that use LDAP authentication groups for user-based access control. – For example, you can define policies that allow or deny access to specific resources based on user group membership.
g. User Authentication: – When a user attempts to access a network resource, FortiGate will use the LDAP server to verify the user’s credentials. – Users will need to enter their AD username and password for authentication.
4. Additional Considerations:
Security: Ensure secure communication between FortiGate and Active Directory by using LDAPS (LDAP over SSL/TLS) for encrypted communication.
User Mapping: FortiGate can map AD groups to local FortiGate groups, simplifying policy management.
Fallback Mechanisms: Configure fallback authentication methods in case the LDAP server is unreachable or for users not in AD.
5. Monitoring and Maintenance:
Regularly monitor the integration for any issues, such as LDAP server connectivity problems or changes in AD group memberships.
Keep FortiGate and Active Directory servers up-to-date with security patches.
