With the increasing distribution of ransomware, it’s very important not only to back up all data, but to recognize the importance of protecting the backup files themselves—after all, the backups themselves could be erased by ransomware. Therefore, modern personal backup software must possess self-protection functions. This is especially important for personal products, because home users don’t usually have organized backup systems like large corporations and even small businesses do.
Comparative testing of 21 popular firewalls to check the quality of protection from attacks, coming from inside the system. In the test we checked the protection on 64 specially developed utilities, checking the protection of processes from quitting, protection from standard outbound attacks, protection from non-standard leaks and protection from non-standard techniques of penetration inside the kernel-mode.
