Question

The BEST defense against successful phishing attacks is:

a. end-user awareness

b. application hardening

c. spam filters

d. an intrusion detection system

Answer 1

The answer is option b spam filters

These filters are algorithmic software which “read” and analyze all incoming and outgoing emails, according to a set of rules, and decide if it is spam or not.

spam filters also check for the following :

• Known viruses or malware, in emails both to and from you.
• Bulk mailing tactics, such as sending many emails at the same time, using proxies to hide the sender IP address, or cloaking the domain of the sender.
• Email domains from known spammers.
