Secure Perimeter Routers & Disable Services & Logging

Perimeter router is router which is used to provide a connection to the untrusted network also known as the internet. It is also used to provide a local area network (LAN) connection among the trusted network which is the internal network inside the organisation.  Thus, to secure the perimeter routers, we can manage the router by logging, disabling of service, software maintenance or configuration maintenance.

  A way on how disabling of service works would be a hacker can use these services to his advantage by gathering information about your router, executing a denial of service (DoS) attack, or attempting to gain unauthorized access. Therefore, you need to disable all of the services on your perimeter router that you are not using or that are unnecessary.

 

  Logging works in many kinds of ways. One good way of doing it would be setting a log severity levels. The severity levels can be use in the form of " more dangerous to less dangerous". The more dangerous one would be level 0 while the less dangerous one would be at the highest level. Level 0 would usually be used in a really emergency situation where as the highest level would be the opposite.
