US DoD threat analysis

The US Department of Defense clearly faces some serious information security risks. According to this presentation about security policies by ex-military man and honeynet security guru Lance Spitzner, the DoD recognizes seven levels of threat. “T1: Inadvertent or accidental events e.g. tripping over the power cord. T2: Passive, casual adversary with minimal resources who is willing to take little risk e.g. listening. T3: Adversary with minimal resources who is willing to take significant risk e.g. unsophisticated hackers. T4: Sophisticated adversary with moderate resources who is willing to take little risk e.g. organized crime, sophisticated hackers, international corporations. T5: Sophisticated adversary with moderate resources who is willing to take significant risk e.g. international terrorists. T6: Extremely sophisticated adversary with abundant resources who is willing to take little risk e.g. well-funded national laboratory, nation-state, and international corporation. T7: Extremely sophisticated adversary with abundant resources who is willing to take extreme risk e.g. nation-states in time of crisis.” Another way of looking at this is as a maturity model for information security. Is your organization ready to face threats at level T4 or T5? Can you afford to address T6?

Trojan used for industrial espionage

A handful of well known companies are caught up in a scandal over the use of a Trojan horse program for industrial espionage against selected targets. The story is a rather sketchy at present but it appears that police discovered the plot following a lead from an Israeli author whose London-based former son-in-law is accused of disclosing parts of a book he was writing. The existence of the Trojan is evidently not in dispute, along with the fact that it was distributed on a 'promotional CD'. The author, however, claims that it is legal and is 'not his fault' if it was misused for illegal/unethical purposes.

ISO 27000-series security standards

ISO has earmarked the ISO 27000-series for the information security management standards including ISO 17799, BS 7799-2 and a new standard currently in preparation on security management metrics. This new website gives an overview and will gradually become a useful public resource for those implementing the ISO security standards.

The Credit Card Prank II

Humble "retail operatives" (till-clerks) who are supposed to check credit/debit card signatures against those on the cards should actually read them and challenge suspicious signatures. It seems some of them perform absolutely no checks whatsoever. This is another example of why security awareness should extend to everyone in the organization.

2005 AusCERT security survey

The latest AusCERT computer crime and security survey says "Only 35% of respondent organisations experienced electronic attacks that harmed the confidentiality, integrity or availability of network data or systems (compared to 49% in 2004 and 42% in 2003)." ONLY 35%! Am I the only person who finds it perverse to regard a situation in which MORE THAN A THIRD of those surveyed suffered business impacts as a success? 3.5% maybe but not 35. This is an outrageous indictment of the state of information security.

Security lessons learned

"Security isn’t only about protecting your network from external threats; it’s also about protecting against threats from within. The first step to security is awareness; therefore, it’s important that all your employees know not only the potential threats but also how to recognize and prevent such threats. Education and awareness empowers each employee with the knowledge of his role in protecting the organization’s network. This, in turn, will go a long way toward mitigating risk." Well said Doug Schweitzer! This week's Processor magazine has several interesting articles on security awareness and policies.

Malware threats converge

Various infosec professionals have been commenting on the threat posed by new forms of malware used to install cryptic rootkits or spyware without alerting the user to their presence. It seems not all antivirus and antispyware software can detect these. There is a distinct possibility that a very specifically targeted chunk of malware could infect an organization or even an individual person, perhaps to wreak havoc with their systems or to disclose sensitive information. Call me paranoid if you like but the pieces are falling into place.

A risk management classic

"The crash of a critical legacy system at Comair is a classic risk management mistake ... the legacy system failed, bringing down the entire airline, canceling or delaying 3,900 flights, and stranding nearly 200,000 passengers. The network crash cost Comair and its parent company, Delta Air Lines, $20 million, damaged the airline's reputation and prompted an investigation by the Department of Transportation." 

Executives stalled all attempts to replace the old crew scheduling system until eventually it failed in service. Reading between the lines of the story, however, it is not clear whether the proposed replacements would have presented even greater risks. Risk management decisions can be buggers.

DDoS extortion

Distributed Denial of Service attacks are being used to extort money from on-line businesses. This is hardly hot news but various experts in a Computerworld piece say this is an increasing threat. More interesting is the emergence of commercial tools to mitigate DDoS attacks, giving victims an alternative way to spend their money (I would be surprised if there were no free tools with the same aim out there, at least in development by the wonderful public-spirited open source community).

Insider threat

CERT has released a 45-page report into the threat of sabotage by insiders. As one might expect from CERT, it focuses on the threat to the IT elements with an emphasis on critical infrastructure although it includes examples in commercial settings.

Information Security Policies Made Easy

Version 9 of Charles Cresson Wood's masterpiece contains more than 1,400 infosec policies in 727 just-over-a-dollar-each pages. How this volume of material makes writing policies "easy" is beyond me but some readers claim the book is good for suggesting the breadth of topics that might be covered in any policy area ... just don't try to write your own 727-page policy manual!
Why do we need security awareness?

Fraudulent laptop sales

Police are warning of a street con involving the sale of what purports to be a laptop, only the bags are swapped and victims find they have actually bought a load of rubbish [the police don't actually say which make of PC is involved].

Website certificates

Another excellent US-CERT Cyber Security Tip helps people understand website certificates. This tip is a bit more technical than most but power users and IT workers should be aware of the implications of accepting and trusting digital certificates.

SOX puts audit costs up

A survey attributing $1.4 bn of additional costs to Sarbanes-Oxley compliance includes a subtle message. Banks, insurance and drug companies saw significant increases in their audit costs, but energy, utilities and retail companies saw even greater increases ... presumably implying that they had much more to do to reach compliance.

ST£RLING fraud initiative

The Metropolitan Police, in conjunction with Companies House, is promoting a scheme for UK companies to sign-up for electronic filing of company records to reduce the opportunities for fraud.

Passwords for $3 a pop

Verisign have found that the majority of people asked were willing to reveal their passwords for a $3 Starbucks coffee token. "According to the company, one executive who was too busy to respond to questions but still wanted a gift card sent his administrative assistant back to complete the survey. The assistant promptly revealed both the executive's password and her own." The survey team have no obvious/legal way to verify the passwords (which is presumably why this was labelled a "light-hearted and unscientific survey") but the take-home message in terms of a general disregard for information security is pretty clear.

How not to do security awareness

A somewhat tongue-in-cheek diary/blog by a typical if fictional information security manager shows how security awareness is constantly pushed to the bottom of the in-tray.

New threats and impacts

ComputerWorld points out that new/changing laws such as those concerning the protection of vital information in effect create new liabilities (we would say "impacts") and new threats such as employees or business partners failing to comply with the new laws - in other words they affect information security risks.

More backup tapes missing

There seems to have been a rash of security incidents involving the loss of backup tapes lately. Computerworld is now reporting that Time Warner lost an entire shipment of data backups en route to its off-site storage. The Register outlined a handful of similar incidents, pointing out that identity thieves would love to get their hands on backup tapes containing credit card numbers and other personal details, especially as so few are encrypted.

CCTV effect on crime

A report by the UK Home Office reveals that only one of 13 CCTV systems studied directly produced a statistically significant reduction in crime relative to comparable control areas without CCTV. This runs counter to the general perception, and the implication of previous Home Office and Police statements, that CCTV deters city-center crime. The report has implications for the cost-benefit and risk analysis of CCTV in private/commercial settings.
