Detecting and Avoiding Online Threats
"But if we really want to get serious about stopping [denial-of-service] attacks, then ultimately, we need to try and make the sources of the attacks -- the home computers -- much more secure." - Assoc Prof Chris Leckie
 Chris Leckie Assoc Prof Chris Leckie's research interests are in the field of Artificial Intelligence (AI) and telecommunications. He has made theoretical and practical contributions in areas such as machine learning, fault diagnosis, visualisation, multi-agent systems and design automation. Chris has strong a interest in developing AI techniques for a variety of applications in telecommunications, such as network intrusion detection, network management, optical networks, information retrieval and market analysis. |

Also Mobile Phones with Internet Access may also be a source of concern and being used to access account numbers and passwords.
Internet Banking should only be done in the Bank
and all Financial Information should be secured by the Bank or Financial Institution.

Infected machines more secure
The idea that a compromised machine on a botnet could somehow be more secure than an uninfected machine seems completely spurious to me. Some uncompromised machines may also be less secure, it's true. Most malware infections open up a myriad of further holes that other malware will be able to exploit - an infected machine is far easier to infect further. In fact, there's a sizeable amount of malware out there which will deliberately infect a machine with more malware.
Regardless of whether the assertion is true, it's a completely useless observation - it doesn't matter if the machine is easier or harder to compromise with more malware, the point is that it is been compromised. And the bulk of the time that happens because the average internet user has a fundamental lack of common sense, something which is very difficult for software, security-related or otherwise, to compensate for.
Sources of the attacks
"But if we really want to get serious about stopping [denial-of-service] attacks, then ultimately, we need to try and make the sources of the attacks -- the home computers -- much more secure." - Assoc Prof Chris Leckie
Is this terminology spurious? "The SOURCES of the attacks ... more secure". Are they the sources of the attacks or are they a compromised victim of the source? I think there’s a big difference.
