Have you heard about IPFire's new method of cryptographic kernel rootkit protection? IPFire is an open-source software that protects the network from external attacks and prevents intrusion.
In the latest release oftest v2.25– Core update 142, IPFire has introduced a new method to sign the Linux kernel module cryptographically. As a result of this, the attacker cannot execute an illegal action using a deployed third-party module into the IPFire kernel.
This new approach of kernel rootkit protection can completely restrict the activities of hidden rootkits on the system. Any modification to the kernel code now requires validation using a cryptographic signature to check its authenticity and integrity.
