Implementing IP Whitelisting
To safeguard your network with IP whitelisting, follow these steps:
Identify Trusted IP Addresses
Compile a list of IP addresses that you trust and want to grant access to your network resources. This can include your organization’s own IP addresses, trusted partners, or specific individuals who require access.
Configure Firewall RulesSession Hijacking: An attack where an unauthorized user take...
Access your network’s firewall settings and create rules that allow inbound connections only from the approved IP addresses. Configure the firewall to block all other IP addresses and enable logging to monitor any denied attempts.
Regularly Update Whitelist
Review your whitelist periodically to ensure that it remains up-to-date. Remove any IP addresses that no longer require access and add any new trusted addresses accordingly. Regularly reviewing your whitelist helps maintain the effectiveness of your IP whitelisting strategy.
