Due to the needed speed in the Incident Response (IR) process, the usage of incident response CDs can save precious time. IR CDs usually are Linux distributions. These distributions contain many incident response and digital forensic tools, which aim to boot mainly from the target system to acquire different types of possible evidence without the need to disconnect the hard drive.
This is designed to leave the least traces on the target system, so it boots with write protection enabled by default to all the connected hard drives. This gives the user the ability to grant the write access to the destination hard drive only. It is better to not connect to the destination hard drive until the system boots from the incident response CD. Of course, booting from the IR CD means that the system under investigation is down, and you will start the machine and boot from the CD. No running system memory is available in this case.
IR CDs also have the ability to acquire the memory...
