  • Cloud Computing will bring many benefits to organisations, some of which include reducing operating costs, reducing power consumption and freeing you up to focus on your core business.
    The concept of shifting computing to a shared service provider is not new. What may be new is that the cost of Cloud Computing is falling so dramatically that considering outsourcing to the Cloud is no longer rare, and it is now accessible enough that any individual or organisation can use it to their advantage.

    Above the Clouds: Managing Risk in the World of Cloud Computing
    For Cloud Computing to be a viable option, you need to be confident that your business information will be secure and that the service you offer to your customers will still be reliable. So if you want to adopt a Cloud Computing strategy, you need to make sure you carry out due diligence on the service provider before you entrust this firm with your vital data. However, the author challenges the assumption that Cloud Computing will offer less protection to your data than relying on an in-house server. Buy Now!>

    Cloud Computing not only allows you to make economies of scale; it can also offer you the increased security that comes from sharing the resource. The author argues that moving over to Cloud Computing can actually help to defend your organisation from threats such as denial of service attacks, viruses and worms.

    Cloud service providers will tell you that Cloud Computing is bound to be better, faster and cheaper. The reality is that before switching over to Cloud Computing, you need to think carefully about whether it will really work for your business. This book shows you what you need to do to ensure that with Cloud Computing you will continue to give the standard of service your customers require. It also offers you some valuable tips on how to choose your provider of Cloud services.

    Fighting Computer Crime: A New Framework for Protecting Information

    Risk assessment demands due diligence, which makes business sense and derives organization mission. Due care care is also about applying the specific control that counts. In information security, due diligence means a complete and comprehensive effort is made to avoid a security breach which could cause detrimental effects and identify various threats that may be exploited for a possible security breach.

    Donn Parker defines due care as a “use of resonable safeguards based on the practices of similiar organizations”

    Fred Cohen defines “due diligence is met by virtue of compliance review.”

    Organizations must: (i) periodically assess the security controls in organizational information systems to determine if the controls are effective in their application; (ii) develop and implement plans of action designed to correct deficiencies and reduce or eliminate vulnerabilities in organizational information systems; (iii) authorize the operation of organizational information systems and any associated information system connections; and (iv) monitor information system security controls on an ongoing basis to ensure the continued effectiveness of the controls.

    12 Phishing Threats and Identity Theft

    Category: Email Security,Identity TheftDISC @ 7:22 pm

    Have you ever thought of losing something and you cannot live without it? Yes, that something can be your identity. Phishing is a practice of luring unsuspecting Internet users to a fake Web site by using authentic-looking email with the real organization’s logo, in an attempt to steal passwords, financial or personal information. In daily life people advise to retrace your steps when you lose something. The question is how you retrace your steps on cyberspace where some uber hackers know how to erase their footsteps to avoid detection. It is difficult to find phishers in cyberspace, and jurisdictional issues make it even harder to prosecute them. Then there is an issue of trust that phishers dupe people to believe that their web site is not fraudulent to collect personal/financial information.

    Amongst the financial crisis, phishing might be on the rise because for many organizations information protection might be the last thing on their mind. The FDIC has created a webpage to inform and warn consumers about “phishing.” These days phishers have targeted social network organizations LinkedIn and Facebook where their members have been duped into revealing their sensitive data.

    Mainly phishing attacks are targeted to steal the identity. Now the question is, how easy it is to steal somebody’s identity? Let’s say a phisher has your name and address, and then he/she can get your Social Security number with the search on AccurInt or other personal database website. A Social Security number is not the only bounty a fraudster can find on these websites, other personal/private information is available as well at minimal cost.

    In the table below are the 12 threats to your online identity which can be manipulated in phishing scams, and possible countermeasures to protect your personal and financial information. Some threats are inadequate or no security controls in place. The last row of the table is a monitoring control to identify the warning signs of identity theft.

    [Table=7]

    Organizations should take necessary steps to protect against identity fraud and apply whatever state and federal legislation applies to your business. Organizations which are serious about their information security should consider implementing the ISO 27001 (ISMS) standard as a best practice, which provides reasonable due diligence to protect and safeguard your information.

    Access control fraud and countermeasures

    Category: Access ControlDISC @ 1:22 am

    These days access to the internet is a business requirement. Most businesses are selling their products and services on the internet which sometimes requires customers to have access to the critical assets such as applications and databases. The global growth of the internet has increased complexity and potential risks to these assets. In some cases, one potential breach may put the organization’s very existence at risk.  French bank SociĂ©tĂ© GĂ©nĂ©rale made a frightening announcement in Jan. 2008 that it has uncovered a $7.14 billion US fraud â€” one of history’s biggest.  A trader at the futures desk misled investors in 2007 and 2008 through a “scheme of elaborate fictitious transactions.”


    In a security review, the reviewer will first determine the criticality of an asset and focus on how that asset is accessed by employees, the risks that unauthorized access by insiders or outsiders could pose to the organization, and if access control has sufficient countermeasures in place to mitigate those risks.  In other words, the security review will determine the risk level of access control to a particular asset and what appropriate control should be in place based on level of risk. At the same time, the business’s first priority is to make information available with effective access control in place. Based on criticality, assets subject to security review present different level of risk associated with access control. In other words, “not all data breaches are created equal.”


    Authorization control is utilized to determine access to network resources. Authentication will determine the identity of the user. Authentication verifies that the login belongs to a user who is attempting to gain access to the system which can be obtained through PKI, smart cards, USB devices, tokens and biometrics.  Accounting keeps the records of user activity including what was used, when and for how long. Most of the application and operating systems have strong auditing features in place to track the activities of a user. Accounting records can be very useful for forensic evidence in case of a security breach. Authenticity covers validity of the information, if someone misrepresents your information by claiming that it is his or hers. Authenticity addresses all forms of information misrepresentation and authenticity of the system users.


    In system profiling, the reviewer determines the criticality of access control and the risk posed to an organization where the risk is directly proportional to the criticality of an asset. Higher risk will require stronger controls or perhaps multiple controls. Security review should determine that controls in place are sufficient to avoid unauthorized access and non-repudiation of information and people. In many ways a password is the weakest link in the access control of a network defense. The best passwords are at least 60 random characters, letters, numbers, and punctuation which can be stored on a portable flash drive flash drive, to be retrieved when needed. All the passwords for the critical infrastructure should have these password characteristics. One weak password in the critical infrastructure can become a launching pad to access other resources in the network.


    Security tools can be used to collect user permissions in a spreadsheet, which can be utilized to analyze the effectiveness of authentication, authorization, accounting, and authenticity. This analysis will determine if users have appropriate access based on need, role and security policy of the organization. Non-repudiation is the cornerstone of access control which assures the validity of a transaction and user. Regular monitoring and non-repudiation of users in all facets of access control might be necessary to mitigate the identity fraud associated with high profile assets. Compliance only addresses the bare minimum required to comply with a control but to measure the strength of a control in high profile assets, a security reviewer should use due care to regularly evaluate the effectiveness of access control at all levels. It might not be an example of due diligence when some regulations fail to require data encryption.
