Elcomsoft's Distributed Password Recovery (EDPR) tool that can crack WPA and WPA2 passwords faster has caused concern among users and specialists. The UK's Secure Computing magazine is quoting Global Secure Systems, a provider of security services, as saying that securing a WLAN solely with WPA or WPA2 is now no longer sufficient: additional protection with VPN encryption is necessary.

In the field of IT systems security, concept of” port knocking” is relatively new. However with the passage of time, it is getting popular day by day among system and security administrators.
Port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of pre-specified closed ports. Once a correct sequence of connection attempts is received, the firewall rules are dynamically modified to allow the host which sent the connection attempts to connect over specified port (s).

Mail
"Bombing" is perhaps one of the oldest and certainly considered one of
the "lamest", that is to say; ineffective and immature, methods of
"attack" available to the would-be "script kiddie" or otherwise
malicious user online. Simply dating back to the first time someone
realised hundreds of irrelevant emails sent to someone else's inbox
could be an extreme, and most importantly time wasting, annoyance. The
theory behind the attack is relatively simple; flood your chosen
targets inbox with as many junk emails as possible over a given time
vector; for example an attacker may devote a few hours run time to
sending the "bomb". In
practise the attack is easily achieved with varying degree's of success
by any number of specifically designed programs able to send thousands,
if not tens of thousands, of emails on command over a relatively short
space of time.
