Andy Johnson-Laird, President of Johnson-Laird, Inc., was kind enough to offer advice on three security techniques he recommends to detect and deny hackers, such as those we discussed in last week’s blog post.

  1. Intrusion Detection Systems identify external probing or port scanning of known IP addresses. He describes it as “the equivalent of lying in bed at night and listening for someone rattling your front door handle. It’s a more or less constant rattling when it comes to port scanning.” See
  2. Network Address Translation (NAT-ing) prevents the routing of internal IP addresses. Internal IP addresses will be selected from the range of “non-routable” addresses reserved by the Internet Engineering Task Force and the Internet Assigned Numbers Authority. See

The largely unvetted findings of investigations other federal agencies conducted on job applicants will also be included in the database. In a nutshell, anyone could be detrimentally affected based on inaccurate information and never know it.
