Nobody wants their systems infected with malware. Users are motivated
and happy when you give them the skills necessary to protect themselves.
The bottom line is that educated and aware users will make your life a lot
easier.
Malware Prevention Tips
The secret to preventing damage from a malicious software attack is to keep
from getting malware on your system in the first place. One way to do this is
with a variation on traditional DNS—secure DNS (the 1002 objectives use a
single word: SecureDNS). Secure DNS can describe software or a remote
DNS provider that implements some additional filtering to block your
devices from visiting all kinds of malicious Web sites.
gIf you can’t keep the malware from reaching your system, a good next
step is catching it on the way in the door. As discussed earlier, for example,
all good antivirus/anti-malware programs include a virus shield that scans e-
mail, downloads, running programs, and so on automatically (see Figure 27-
24).
