Computer Hacker Caused Sewage Overflows, Police Say

An alleged computer hacker caused raw sewage to overflow on Queensland's Sunshine Coast by using radio transmissions to alter council sewage pump stations, police said today. The charges include stealing, computer hacking and using radio communications equipment without authority. Police will allege the man caused the overflows of sewage into Maroochy Shire waterways late last year and early this year using radio transmissions to alter council sewage pump stations.

AISEP Evaluation
  • Evaluation is the thorough examination of a product’s security claims using a defined criteria.
  • Australia uses two evaluation criteria
    • Common Criteria
    • ITSEC
  • Common Criteria is the more recent evaluation criteria
    • Broad scope of mutual recognition internationally
concept of assurance
Concept of Assurance
  • Assurance is:
    • The degree of confidence in the claimed security features of a product or system.
    • Defined by a Security Target.
the epl
  • DSD lists products that have completed evaluation on the EPL (certified)
    • Certification Reports available
    • Use in conjunction with the published Security Target
  • Products that are ‘In-Evaluation’ are also listed on the EPL
    • Buyer beware
    • Can not provide the same level of assurance
and this is good because
And this is good because …
  • there are products available which are known to perform appropriately
  • not just for government use
    • use in the private sector can help to promote a more secure IT environment
