Another example of how the FIPS security categorizations can be used to decide if each of the information security risk mitigation described in the FGDC guidelines is the redaction of classified documents before released to the public. There is no doubt that covert operations are taking place without public knowledge. An example is the hunt for…[Read more]

Just restating what everybody has already said:
The FGDC guidelines for safeguarding Geospatial data are:
1. Change the data – changing the data to remove sensitive information and then make the changed data available without further safeguards.
2. Restrict the data by adding additional access controls or Defense-on-depth to protect the data…[Read more] -

Bilaal, thanks for the post.
I just read on ZDNet that ransomware is now the biggest cybersecurity threat mainly because it uses simple attack and the willingness of its victims to pay to unlock their files. This willingness makes it more profitable for cybercriminals to use ransomware for a quick profit. Even the FBI encourages victims to…[Read more]

Wow, one and a half million dummy accounts, over $400,000 in fees, and 5300 employees. How can a bank of this magnitude have such weak internal controls. Knowing that this bank has so much control over a person’s financial record is outrageous. Opening bank accounts and credit cards requires some very sensitive information like SSN, and…[Read more]

Sean, thanks for the post. I think that people are the weakest link in any security program. Even with the right technology (hardware or software), if not configured or implemented correctly, can cause business disruptions.

Thanks for this post Wayne. Like you I was a little blown away from the article. I learned two things from this article; what an air-gap network/computer is and how they can be compromised.
