  • 3. For the past few years, we have seen the birth to a gamut of new age cyber threats and how they are encroaching more into every sphere our lives and they come in multi-dimensions. In 2011, we have also seen the emergence of social media and mobile devices etc that has complicated the global cyber security landcape which is further worsened by users’ ignorance, technical incompetency, and lack of strategic cyber security collaboration. We take necessary steps to curb this situation, among others knowledge sharing initiatives via e-Security Bulletin. It is expected that 2012 and beyond will be challenging as cyber crime is consistently becoming sophisticated due to the rapid advancement in technology. In 2011, CyberSecurity Malaysia has received 5,328 online fraud incidents that include various types of Internet scams. That number alone is more than the total number of similar incidents in 2010 and double of those reported in 2009. It is not an exaggeration to say that internet scams i.e. love scams, financial fraud, identity theft etc are fast becoming the crime of choices. For every investigation in the news, there are hundreds that will never make the headline. We learn that criminals can hardly get caught, and even if they do, they can be hardly convicted. As the technology evolves, the risks posed by cyber threats also continue to grow in both scale and sophistication. New techniques and methods may emerge, and the traditional ones would become obsolete. As such, our attitudes towards cyber security should also evolved and innovated. The explosion of Internet has also created the phenomenon towards “digital hacktivism“. 2011 also witnessed hacktivist groups such as “Anonymous” went rampage, worst than the year before. Indeed, “Anonymous” is a revolutionary group, and it will be more sophisticated in the future. Hence our approach towards combating it has to be equally revolutionary. Cyber security requires an innovation or perhaps a fundamental shift in approach towards solving the problems; and we have to act fast to stay ahead. 2012 onward, we need to understand the evolving cyber threats and how they work, and to develop the tools and methods to combat them. We should create more robust and resilient cyber space that can withstand attacks, and also help detect and prevent cyber attacks from occurring. We also need talented people with innovative ideas and commitment from both local and global key cyber security players. Until next time, have a prosperous and secure year ahead. Thank you. Thank you and warmest regards, Lt Col Prof Dato’ Husin Jazri (Retired) CISSP CBCP CEH ISLA CEO, CyberSecurity Malaysia Greetings and welcome to the first edition of eSecurity Bulletin for 2012. Some interesting topics have been lined up in this edition such as security in Software Development Life Cycle (SDLC), principles of security and information security risk management. Also, short but important tips on how to secure your iPad is included. Please spend time to read through the articles. I would like also to highlight our CyberSecurity Clinic which started its operation in September last year. Some of the services being offered are data recovery (for your hard disk, thumb drive, memory card or server), data sanitization and ICT services. Please visit the CyberSecurity Clinic website (www.cybersecurityclinic.my) for further information. Last but not least, I want to take this opportunity to thank all contributors for their valuable knowledge sharing. I look forward for more contributions from the security professionals.

Benefits of ISO/IEC 27005 In the authors’ opinion, there are several key advantages when organisations refer to ISO/IEC 27005 for implementing information security risk management. Firstly, this standard can be used by any type of organisation. Secondly, this standard supports the requirements of information security risk assessment specified in ISO/IEC 27001. And thirdly, this standard, which has been revised to align with three other risk management standards, can be used by organisations that wish to manage their information security risks in similar fashion to the way they manage other risks. This standard is applicable to any type of organisation Figure 1: ISO/IEC 27005 Information Security Risk Management Processes One of the attractions of ISO/IEC 27005 is the risk management processes described in the standard which is The standard supports risk applicable to all organisations, no matter assessment requirements specified the size or type.
