We are using Firepower for outbound/inbound traffic control and management as well as for our internal security. We are using it for LAN security and VMware network security. It is a hardware device, and it is deployed on-prem.
Our target is to make our network 100% secure from the outside and inside traffic. For that, we are using the latest versions, updates, patches, and licenses. We have security policies to enable ports only based on the requirements. Any unnecessary ports are disabled, which is as per the recommendation from Cisco. For day-to-day activity monitoring and day-to-day traffic vulnerabilities, we have monitoring tools and devices. If there is any vulnerability, we can catch it. We are constantly monitoring and checking our outside and inside traffic. These are the things that we are doing to meet our target of 100% security.
We have a number of security tools. We have the perimeter firewalls and core firewalls. For monitoring, we have many tools such as Tenable, Splunk, etc. We have Cisco Prime for monitoring internal traffic. For malware protection and IPS, we have endpoint security and firewalls. The outside to inside traffic is filtered by the perimeter firewall. After that, it goes to the core firewall, where it gets filtered. It is checked at port-level, website-level, and host-level security.
We have the endpoint security updated on all devices, and this security is managed by our antivirus server. For vulnerabilities, we have a Tenable server that is monitoring all devices. In case of any vulnerability or attacks, we get updated. We are also using Splunk as SIEM. From there, we can check the logs. If any device is attacked, we get to know the hostname or IP address. We can then check our monitoring tool and our database list. We can see how this attack happened. We have configured our network into security zones. We have zone-based security.
