The systems described in the question are using blacklists, which block specific IP addresses, Internet domains, etc. This is different from whitelists, which only allow specific entries, and intrusion detection software, which detects and alerts for potential intrusions. Anti-virus software is focused on detecting and removing viruses and other malicious software, but not necessarily on controlling access. Access restriction software is a more generic term and could encompass a variety of tools, but it doesn't specifically describe the use of blacklists.
