Which of the following is the most helpful way to protect a host against application level backdoor trojans from infecting a system?
- Install a personal firewall on the host which only allows outbound TCP/UDP connections.
- Block all incoming network connections to the host.
- Install up to date anti-virus software on the host.
- Create an access control list on the switch to always block traffic to the host on TCP ports 135-139.
Explanation:
One of the most effective ways of protecting a host against application level backdoor trojans is to install up to date anti-virus software on the host. Any form of network blocking or firewalls on the host may help, however the system will still be vulnerable to attacks locally or over a modem.
