Intrusion detection system


An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. 

IDS come in a variety of “flavors” and approach the goal of detecting suspicious traffic in different ways. There are network based (NIDS) and host based (HIDS) intrusion detection systems. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system. 

Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, and reporting attempts. In addition, organizations use IDPSes for other purposes, such as identifying problems with security policies, documenting existing threats and deterring individuals from violating security policies. 

IDPSes have become a necessary addition to the security infrastructure of nearly every organization.


Host provider change the IDS 

"
During the build, we've found that there weren't enough span sessions in the existing cabinet to add the IDS.  Because of this, we will need to set up a new firewall in another location so that the IDS device can be installed along with it.  We will copy the configuration from the existing firewall to the new one and later on do the switchover.  The downtime impact during the switchover will probably be a minute or so.  Below is the authorization needed to proceed with the new firewall provisioning.

IPv4 header to requests when a client is using IPv6

  What is Pseudo IPv4? As a stopgap to accelerate the adoption of IPv6, Cloudflare offers Pseudo IPv4 which supports IPv6 addresses in legacy applications expecting IPv4 addresses. The goal is to provide a nearly unique IPv4 address for each IPv6 address, using Class E IPv4 address space, which is designated as experimental and would not normally see traffic. To learn more see  here . Options Add header:  Add additional Cf-Pseudo-IPv4 header only Overwrite headers:  Overwrite the existing Cf-Connecting-IP and X-Forwarded-For headers with a pseudo IPv4 address Cloudflare
