The Importance of Security Standards

Security Standards and Guidelines

Standards can be contrasted with another category of documents, generally referred to as guidelines. Both standards and guidelines provide guidance aimed at enhancing cyber security, but guidelines usually lack the level of consensus and formality associated with standards. Some standards, such as ANSI Standards and FIPS Publications, are easily recognized because they include the term standard in their titles. Others are harder to recognize. For example, standards issued by the International Telecommunications Union (ITU), an international standards developer, are designated as Recommendations. A standard issued by the IETF starts out as an RFC and retains that designation even after being adopted as a standard. In other cases, documents that are not standards in the strict sense of the word may be treated as such by an organization if it suits the organization’s needs. For example, many US and international organizations and businesses have adopted National Institute of Standards and Technology (NIST) Special Publications as standards, even though those documents are published as guidelines for use by US Federal agencies.

Some organizations develop both standards and guidelines. For example, in addition to international standards, ISO/IEC issues several types of guidelines, including technical specifications, publicly available specifications (PAS), and technical reports, according to the ISO/IEC Directives, Part 1, Section 3 [7]. A technical specification may be published when the immediate release of an international standard is not feasible, such as when the subject in question is still under development. A PAS may be an intermediate specification published prior to the development of a full international standard, or in International Electrotechnical Commission (IEC) it may be a “dual logo” publication published in collaboration with an external organization. A PAS does not fulfill the requirements for a standard. A technical report is an informative document generally intended to educate the reader, not to specify an international standard.

 

Why do we need standards?

 

Protecting your organization’s information is critical for the successful management and smooth operation of your organization. Following a Standard will aid your organization in managing and protecting your valuable data and information assets.

Standards provide us with a common set of reference points to enable us to evaluate whether an organization has processes, procedures and other controls in place that meet an agreed minimum requirement.  If an organization is compliant/meets a certain standard then it gives third parties such as customers, suppliers and partners confidence in that organization’s ability to deliver to that standard.  It can also provide an organization with a competitive advantage over other organizations.  For example, an organization that is compliant with a security standard may have an advantage over a competitor who does not when customers are evaluating their products or services.

Standards can also help organizations meet with regulatory requirements such as the Data Protection Act, SOX, HIPAA etc.  By using a standard to create a strong foundation for managing and securing your systems. you will find it easier to meet existing and new regulatory requirements easier than an organization that does not.

Benefits in following Standards

Compliance with legislation: Having a structured Information Security   Management System in place makes the task of compliance much easier.

Improved Management: Knowing what is in place and how it should be managed and secured makes it easier to manage information resources within a company.

Improved Customer and Partner Relationships: By demonstrating the company takes information security seriously, customers and trading partners can deal with the company confidently knowing that the company has taken an independently verifiable approach to information security risk management.

 

Reduced Costs: A standards-based approach to information security ensures that all controls are measured and managed in a structured manner.  This ensures that processes and procedures are more streamlined and effective thus reducing costs.

Some companies have found they can better manage the tools they have in place by consolidating redundant systems or re-assigning other systems from assets with low risk to those with higher risk.

Market Reach:  Improved market access as a result of increased competitiveness and efficiency, reduced trading costs, simplified contractual agreements, and increased quality.

Increased reliability and security of systems: Security is often defined as protecting the Confidentiality, Integrity and Availability of an asset.  Using a standards-based approach, which ensures that adequate controls, processes and procedures are in place will ensure that the above goals are met.  Meeting the CIA goals of security will also by default improve the reliability, availability and stability of systems.

Increased profits: Having stable, secure and reliable systems ensures that interruptions to those systems are minimized thereby increasing their availability and productivity.  In addition to the above, a standards-based approach to information security demonstrates to customers that the company can be trusted with their business.  This can increase profitability by retaining existing, and attracting new, customers.
