This is an excellent banner for your firewalls, routers and other network devices, some companies have a short sweet banners but some do scary ones and as per compliance policies and rules you need to publish a banner on your network security devices before the user logs on. Hereś the banner you can use but just using this banner is not going to help you from securing your devices, that will happen only when you get back to work, update your software, change default passwords, perform regular audit and most important logging at multiple locations.
