We require the personal firewalls to prevent data and identity theft. They should implement a packet filter functionality to prevent direct online attacks – i.e. not to let the malware get in. Personal firewalls should control the software installed on the computer to prevent the malware to integrate itself into the operating system. Then the malware should not be able to get the user's private data, thus anti-sniffing, anti-keylogging and personal data protection features should be implemented too. And even if the malware succeeded to collect the information it should not be allowed to send it outside the protected system and this means the implementation of the outbound network traffic control.
Moje definice /a mnoha lidí zde na poradně/ je:
