What is commonly known as ISO 27001 is an information security management system. This is an expansion of ISMS standard. Its full name is ISO 27001. It was introduced in 2005 by the International Organization for Standardization (ISO) in collaboration with the International Electro Technical Commission (IEC). There are various features and benefit available to organization by getting the ISO 27001. Organizations can apply for independent certifications of their ISMS. The standard covers all types of organizations (like commercial enterprises, government agencies and non-profit organizations) and all sizes from micro-businesses to huge multinationals.
ISO 27001 generally plays a very important role in monitoring, review, maintenance and improvement of an information security management system. It works like an overall management and control framework for managing an organization’s information security risks. There is no specific code or condition is available to stop the management function using this certificate. Bringing information security under management control is a necessity for sustainable, directed and continuous improvement of an information security management system. In doing so, it generates greater interest in and awareness of information security that seeks an independent certification of its ISMS. Every organization should try to get such kind of quality certificate, this help the organization to gain more profit in business as well as to get brand name in society.
It is released public on Oct 2005 but is based heavily upon the British Standard, bs7799-2. Bs7799 itself was also released in same year. This contains some set of rules and regulation followed by the organization. Around more than ten thousand institution applied and obtained this certificate.
ISO 27001 is not only an advanced version of BS7799-2 and also inherit other international standard also there are various certification released by government and well so international local bodies to make sure organization is running properly. Organization can apply for this kind of certificate and show their code of conduct to public. ISO 27001 is often considered to be the most important and more reliable in the society hence many organizations like to get the ISO 27001 certificate. The ISO 27000 is also partnered with the many ISO certificates like ISO 9001, ISO 14001, etc. ISO 27001 is applied by organization to show that they are very good in ethics and following all the rules and regulation properly put forward by their government.
The prime objective of this standard normally supports to establish, design, implement and manage an effective information management system which protects information of an organization from any risks. Decision adoption of this standard should be followed in every organization. The certificate also keen in valuing the people which were working in company as well as how company treating employee.
There are various sub standards also present in the ISO 27001. Each sub section denotes some specific quality and specification should be followed by the organization. There also a standard called plan to check, this help the organization to plan their quality and they can check whether they attained or not. ISO 27001 also help the organization to maintain ethic rules in as well as help the organization in business by getting new order. Organization also gain more profit by using this ISO 27001 certificate. The benefits of ISO 27001 are not only numerous but also diverse.
Design and manage an independent information management system. ISO 27001 can be used within any organization to design and formulate its specific set of security requirements and desired objectives. It can also help in seeing that the plans are implemented and the desired security objectives are met. This standard makes the implementation process of security management system more formal and rigorous apart from diminishing the risks considerably.
Minimize and manage security risk. ISO 27001 helps to make sure that unacceptable information security risks are avoided. It further helps in managing any risk in the most cost effective manner.
Win the confidence of business partner. Certification improves the organizations marketing potential by causing its business partners to be convinced of the stable state of the organization’s information security. It also relieves the business associates of the necessity of carrying out its own research on the organization’s information security management.
Organizations can use this standard to provide relevant information about information security policies, directives, standards and procedures to its trading partners as well as any other organization that they interact with for operational or commercial purposes.
Analyze existing information security management process. ISO 27001 helps in identifying, understanding and analyzing the status of the current information security management processes. It is utilized by internal as well as external auditors of organizations to explain the information security policies of the organization and also the directives and standards that it adopts and to what extent the organization complies with those policies, directives and standards.
Interpretability. If the partner organizations both follow ISO 27001 standardization, then they can achieve a comfortable level of interoperability even though they may belong to very different backgrounds because of the common set of standardization guidelines that they follow.
Quality assurance. Whether it is the organization or the business partners, there should be some quality in the information security system and hence of the organization in general since a clearly defined standardization process is applied.
Bench marking. An organization can use the ISO 27001to measure its status against that of its competitors. They can emphasize on their current rank and the developments that they make as opposed to their rivals.
General security awareness. The ISO 27001 is a formal set of specifications that establishes, manages and controls and implements a security management system and hence avoids any possible information security risks. In doing so, it generates greater interest in and awareness of information security that seeks an independent certification of its ISMS.
Alignment of staff. Implementation of this standard generally demands the involvement of both the business management staff and the technical staff. Hence, as a consequence, communication and information technology coordination is achieved easily in greater measure.
This is a good certification standard for a company to reach a new quality goal for raising the bar to the next level.

The Magic of Risk Management Studio is found in how categories, threats and controls are connected. In short, each category has a number of threats threatening it, and each threat has a number of controls that mitigate that threat. Lets look at each part in more detail.
The Role of Assets in Risk Assessment
We use Categories to group Assets together. You may also view Category(s) as a sort of prototype for Assets. During Risk Assessment, you must define the relevant Assets for your scope. So, each Asset should be placed in at least one Category. Risk Management Studio provides a predefined set of Categories which have been defined with Information Security in focus.
Threats are anything that can potentially damage your assets(physical or informational). Each Threat has a list of Categories which they threaten. When you create an Asset and place it in a specific Category, it inherits all the Threats which threaten that Category. So, when you take your newly defined Asset and use it in an Assessment, all relevant Threats connected to the asset,will be loaded into the Assessment, ready to be evaluated. Once Threats have been loaded into an Assessment, they are referred to as Risks.
Handling and Treating Risk
Let us take an example. Let us define a Category named Documents and list several possible threats, for example Theft and Fire. We Assign those Threats to the Category. Then we define our concrete Asset called Financial Records, placing it in the category Documents. Now we add a new Asset to our Assessment. Under that asset, 2 Risks corresponding to the the Threats that threaten the Category Documents, namely Theft and Fire, will be automatically added.
This example is simplified, but you can take a look at the data provided with Risk Management Studio, where our in-house experts have defined Categories and Threats based on their expertise with ISO 27001.
In addition to the connection between Threats and Categories, there is a connection between Threats and Controls from ISO 27001. Each Threat has a list of Controls which mitigate that threat. This connection is important when we take a Risk Assessment and choose to continue work in relation to a specific standard. The resulting object is then called a Risk Treatment.
When a Risk Treatment is created from a Risk Assessment and a Standard, all controls from the Standard are placed in the Risk Treatment. In addition to that, each Risk is connected to each Control from the list of mitigating Controls defined in the corresponding Threat. This means that if your Assessment only has a small number of Risks, and each Risk is only mitigated by several Controls, your Risk Treatment will only contain direct relations between those Risks and Controls. However, since the standard tells you a conscious stance must be taken towards all Controls, they are all included in the Risk Treatment.

As information technology increasingly falls within the scope of corporate governance, so management must increasingly focus on the management of risk to the achievement of its business objectives.
There are two fundamental components of effective management of risk in information and information technology: the first relates to an organization’s strategic deployment of information technology in order to achieve its corporate goals, the second relates to risks to those assets themselves. IT systems usually represent significant investments of financial and executive resources. The way in which they are planned, managed and measured should therefore be a key management accountability, as should the way in which risks associated with information assets themselves are managed.
Clearly, well managed information technology is a business enabler. Every deployment of information technology brings with it immediate risks to the organization and, therefore, every director or executive who deploys, or manager who makes any use of, information technology needs to understand these risks and the steps that should be taken to counter them.
ITIL has long provided an extensive collection of best practice IT management processes and guidance. In spite of an extensive range of practitioner-orientated certified qualifications, it is not possible for any organization to prove – to its management, let alone an external third party – that it has taken the risk-reduction step of implementing best practice.
More than that, ITIL is particularly weak where information security management is concerned – the ITIL book on information security really does no more than refer to a now very out-of-date version of ISO 17799, the information security code of practice.
The emergence of the international IT Service Management ISO 27001 and Information Security Management (ISO20000) standards changes all this. They make it possible for organizations that have successfully implemented an ITIL environment to be externally certificated as having information security and IT service management processes that meet an international standard; organizations that demonstrate – to customers and potential customers – the quality and security of their IT services and information security processes achieve significant competitive advantages.
Information Security Risk
The value of an independent information security standard may be more immediately obvious to the ITIL practitioner than an IT service management one. The proliferation of increasingly complex, sophisticated and global threats to information security, in combination with the compliance requirements of a flood of computer- and privacy-related regulation around the world, is driving organizations to take a more strategic view of information security. It has become clear that hardware-, software- or vendor-driven solutions to individual information security challenges are, on their own, dangerously inadequate. ISO/IEC 27001 (what was BS7799) helps organizations make the step to sytematically managing and controlling risk to their information assets.
IT Process Risk
IT must be managed systematically to support the organization in achieving its business objectives, or it will disrupt business processes and undermine business activity. IT management, of course, has its own processes – and many of these processes are common across organizations of all sizes and in many sectors. Processes deployed to manage the IT organization itself need both to be effective and to ensure that the IT organization delivers against business needs. IT service management is a concept that embraces the notion that the IT organization (known, in ISO/IEC 20000 as in ITIL, as the “service provider”) exists to deliver services to business users, in line with business needs, and to ensure the most cost-effective use of IT assets within that overall context. ITIL, the IT Infrastructure Library, emerged as a collection of best practices that could be used in various organizations. ISO/IEC 20000, the IT service management standard, provides a best-practice specification that sits on top of the ITIL.
Regulatory and Compliance Risk
All organizations are subject to a range of information-related national and international legislation and regulatory requirements. These range from broad corporate governance guidelines to the detailed requirements of specific regulations. UK organizations are subject to some, or all, of:
* Combined Code and Turnbull Guidance (UK)
* Basel2
* EU data protection, privacy regimes
* Sectoral regulation: FSA (1) , MiFID (2) , AML (3)
* Human Rights Act, Regulatation of Investigatory Powers Act
* Computer misuse regulation
Those organizations with US operations may also be subject to US regulations such as Sarbanes Oxley and SEC regulations, as well as sectoral regulation such as GLBA (4), HIPAA (5) and USA PATRIOT Act. Most organizations are possibly also subject to US state laws that appear to have wider applicability, including SB 1386 (California Information Practice Act) and OPPA (6) . Compliance depends as much on information security as on IT processes and services.
Many of these regulations have emerged only recently and most have not yet been adequately tested in the courts. There has been no co-ordinated national or international effort to ensure that many of these regulations – particularly those around personal privacy and data protection – are effectively co-ordinated. As a result, there are overlaps and conflicts between many of these regulations and, while this is of little importance to organizations trading exclusively within one jurisdiction, the reality is that many enterprises today are trading on an international basis, particularly if they have a website or are connected to the Internet.
Management Systems
A management system is a formal, organized approach used by an organization to manage one or more components of their business, including quality, the environment and occupational health and safety, information security and IT service management. Most organizations – particularly younger, less mature ones, have some form of management system in place, even if they’re not aware of it. More developed organizations use formal management systems which they have certified by a third party for conformance to a management system standard. Organizations that use formal management systems today include corporations, medium- and small-sized businesses, government agencies, and non-governmental organizations (NGOs).
Standards and Certifications
Formal standards provide a specification against which aspects of an organization’s management sytsem can be independently audited by an accredited certification body and, if the management system is found to conform to the specification, the organization can be issued with a formal certificate confirming this. Organizations that are certificated to ISO 9000 will already be familiar with the certification process.
Integrated Management Systems
Organizations can choose to certify their management systems to more than one standard. This enables them to integrate the processes that are common – management review, corrective and preventative action, control of documents and records, and internal quality audits – to each of the standards in which they are interested. There is already an alignment of clauses in ISO 9000, ISO 14001 (the environmental management system standard) and OHSAS 18001 (the health and safety management standard) that supports this integration, and which enables organizations to benefit from lower cost initial audits, fewer surveillance visits and which, most importantly, allows organizations to ‘join up’ their management systems.
The emergence of these international standards now enables organizations to develop an integrated IT management system that is capable of multiple certification and of external, third party audit, while drawing simultaneously on the deeper best-practice contained in ITIL. This is a huge step forward for the ITIL world.

This ISO 27001 International Standard covers all types of organizations (e.g. commercial enterprises, government agencies, non-profit organizations). This International Standard specifies the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining and improving a documented ISMS within the context of the organization’s overall business risks. It specifies requirements for the implementation of security controls customized to the needs of individual organizations or parts thereof.
The ISMS is designed to ensure the selection of adequate and proportionate security controls that protect information assets and give confidence to interested parties.
NOTE 1: References to ‘business’ in this International Standard should be interpreted broadly to mean those activities that are core to the purposes for the organization’s existence.
NOTE 2: ISO/IEC 17799 provides implementation guidance that can be used when designing controls.
The requirements set out in this International Standard are generic and are intended to be applicable to all organizations, regardless of type, size and nature. Excluding any of the requirements specified in Clauses 4, 5, 6, 7, and 8 is not acceptable when an organization claims conformity to this International Standard.
Any exclusion of controls found to be necessary to satisfy the risk acceptance criteria needs to be justified and evidence needs to be provided that the associated risks have been accepted by accountable persons. Where any controls are excluded, claims of conformity to this International Standard are not acceptable unless such exclusions do not affect the organization’s ability, and/or responsibility, to provide information security that meets the security requirements determined by risk assessment and applicable legal or regulatory requirements.
NOTE: If an organization already has an operative business process management system (e.g. in relation with ISO 9001 or ISO 14001), it is preferable in most cases to satisfy the requirements of this International Standard within this existing management system.

Most organizations are dependent upon their information and business systems, leaving them exposed to critical loss in the aftermath of a security breach. Fortunately, by implementing an information security management system (“ISMS”), as outlined in the only internationally accepted standard/code to address information security, a business can significantly reduce the risk of a security breach.
ISO/IEC 17799:2005 (“ISO 17799″), known as the Code of practice for information security management, was developed by an IT Security Subcommittee of the International Organization for Standardization and was published in June 2005. ISO 17799 is superior to other security standards because it is globally accepted and comprehensive. ISO 17799 has been cleverly crafted to work well across industries and geographies. Also, the International Organization for Standardization has consciously made this standard consistent with most other existing information security audit and control standards, such as those developed by the NIST (National Institute of Standards and Technology). Therefore, ISO 17799 can be the common framework that links to all other standards, regulatory requirements and corporate governance initiatives.
ISO 17799 provides practical guidelines for developing organizational security controls and effective security management practices. An ISO 17799 evaluation results in a snapshot of the company’s security infrastructure, in that it provides a high-level view of how well (or how badly) a company implements information security. This standard is a great tool for companies whether establishing or improving information security within their organization.
The information security process traditionally has been based on sound best practices and guidelines, with the goals of preventing, detecting and containing security breaches, as well as restoration of the affected data to its previous state. While this cumulative wisdom of the ages is valid, it is also subject to various interpretations and implementations. ISO 17799 offers an achievable benchmark against which to build organizational information security.
Control Selection based on Risks Identified
ISO 17799 consists of 39 security controls, which can be used as a basis for a security risk assessment. The controls encompass all forms and types of information, whether they are electronic files, paper documents or various forms of communications such as email, fax and spoken conversations. The standard sets out a variety of hardware and software considerations, policies, procedures and organizational structures that protect a company’s information assets from a broad range of modern security threats and vulnerabilities. How organizations shape their information security programs will depend on the unique requirements and risks they face. An organization should only deploy controls that relate to, and are in proportion to, the actual risks it faces.
Controls can also more simply be described as the countermeasures for risks. Apart from knowingly accepting risks considered acceptable, or transferring those risks (through insurance) to others, there are essentially four types of control:
1. Deterrent controls reduce the likelihood of a deliberate attack.
2. Preventative controls protect vulnerabilities and make an attack unsuccessful or reduce its impact.
3. Corrective controls reduce the effect of an attack.
4. Detective controls discover attacks and trigger preventative or corrective controls.
It is essential that any controls that are implemented are cost-effective. The cost of implementing and maintaining a control should be no greater than the identified and quantified cost of the impact of the identified threat (or threats). It is not possible to provide total security against every single risk; the trade-off involves providing effective security against most risks. No board should sign off on any ISMS proposal that seeks to remove all risk from the business – the business does, after all, exist within a risk framework and, since it is impossible to exist risk-free, there is little point in proposing to eliminate every risk.
No organization should invest in information security technology (hardware or software) or implement information security management processes and procedures without having carried out an appropriate risk and control assessment that assures them that:
- The proposed investment (the total cost of the control) is the same as, or less than, the cost of the identified impact;
- The risk classification, which takes into account its probability, is appropriate for the proposed investment; and
- Mitigating the risk is a priority – i.e. all the risks with higher prioritization have already been adequately controlled and, therefore, it is appropriate now to be investing in controlling this one.
Once information security needs and requirements are identified, a suitable set of controls from ISO 17799 can be established, implemented, monitored, reviewed and improved upon in order to ensure that the specific security objectives of the organization are met.
ISO 17799 is a comprehensive information security code of practice that provides enterprises an internationally recognized and structured methodology for information security. In addition to ISO 17799, the International Organization for Standardization also published ISO 27001, which specifies a number of requirements for establishing, implementing, maintaining and improving an ISMS using the controls outlined in ISO 17799.
ISO 27001 is the formal standard against which an organization may seek independent certification of their ISMS. While certification is entirely optional, as of January 2007, over 3000 organizations world-wide were ISO 27001 certified, demonstrating their commitment to information security. Organizations may be certified compliant with ISO 27001 by a number of accredited certification bodies worldwide. ISO 27001 certification generally involves a two stage audit process, with a “table top” review of key documentation at the first stage and a more in-depth audit of the ISMS at the second stage. The certified organization would need to be re-assessed periodically by the certification body.
In summary, organizations face threats to their information assets on a daily basis. At the same time, they are becoming increasingly dependent on these assets. Technical solutions are only one portion of a holistic approach to information security. Establishing broad information security requirements in the framework of the organization’s own unique risk environment is essential.
