A Full Guide to Information Security Standards Based on ISO 27001 and ISO 27002
In the complicated world of information security, ISO 27001 and ISO 27002 are two guidelines that businesses that want to protect their important information assets always look to. These standards are linked, but they do different things that work well together in the field of information security management. The goal of this piece is to give you a full picture of ISO 27001 and ISO 27002 by looking at their differences, how they work together, and how they can be used in today’s digital world.
What ISO 27001 and ISO 27002 Are and How They Came to Be
To really understand these norms, it’s important to look at how they came to be. The British Standard BS 7799, which came out in 1995, is where both ISO 27001 and ISO 27002 got their start. The International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO) later accepted this standard and made it the norm around the world.
One of the first versions of ISO 27001 came out in 2005. The most recent big update was in 2013 (ISO/IEC 27001:2013). It took the place of the BS 7799-2 standard.
Another difference is that ISO 27002 grew out of BS 7799-1. It was first released as an ISO standard in 2000 under the name ISO/IEC 17799. In 2007, it was changed to ISO/IEC 27002 to match the naming scheme for the ISO 27000 series. It is now called ISO/IEC 27002:2013.
This chronological development brings up an important point about both standards: they are not fixed documents, but living documents that change as dangers and tools in information security do.
What ISO 27001: The Framework for Information Security Management Really Means
ISO 27001 is a standard for an Information Security Management System (ISMS). The method makes it easy to keep private company data safe by handling it in a planned way. These are the most important parts of ISO 27001:
The goal of ISO 27001 is to set the standards for creating, deploying, managing, and always making an ISMS better within a company.
Structure: The standard is made up of several clauses:
Clause 4: The organization’s setting
- Clause 5: Leadership 6. Clause 7: Planning 8. Clause 9: Operation 9. Clause 10: Evaluating performance
Clause 10: Getting better
List of rules in Annex A
method Based on Risk: ISO 27001 stresses a method to information security that is based on risk. Information security risks must be found, analyzed, and evaluated by organizations, and then the right controls must be put in place to reduce these risks.
Process Orientation: The standard uses the Plan-Do-Check-Act (PDCA) model, which encourages a process of always getting better.
Certification: After an audit by a recognized certification group, an organization can get ISO 27001 certification, showing that they follow the standard.
Getting to the bottom of ISO 27002: The Code of Practice for Information Security Controls
Even though ISO 27002 is linked to ISO 27001, it is used for a different thing. It is a set of rules for how to handle computer protection. These are the most important parts of ISO 27002:
The goal of ISO 27002 is to help organizations set information security standards and handle information security better. It does this by giving advice on how to choose, set up, and manage controls.
organization: ISO 27001’s 14 control clauses make up the organization of the standard. It gives the following for each control:
A control statement Advice on how to put it into action
Some other things
ISO 27002 is flexible because it uses suggested wording and gives suggestions instead of standards. This lets groups change the advice to fit their own needs.
Broad Coverage: The standard includes many different areas of information security, such as physical and human resource security, as well as cryptography and human resource security.
Not certifiable: Companies can’t get ISO 27002 certification, but they can get ISO 27001 certification. More than a list of rules, it’s meant to be used as a reference.
What’s Different In the space between ISO 27001 and ISO 27002
Even though ISO 27001 and ISO 27002 are very similar, they are not the same in several important ways:
ISO 27001 is a standard for management systems, and ISO 27002 is a set of rules for how things should be done.
The goal of ISO 27001 is to define the standards for an ISMS, and the goal of ISO 27002 is to provide operational advice for information security controls.
Certification: Companies can get ISO 27001 certification but not ISO 2702 certification.
Language: ISO 27001 uses the word “shall” to say what must be done, while ISO 27002 uses the word “should” to say what should be done.
Scope: ISO 27001 is about the whole ISMS, while ISO 27002 is only about putting information security rules in place.
What ISO 27001 and ISO 27002 Have in Common: How They Help Each Other
Even though they are different, ISO 27001 and ISO 27002 are meant to work together:
Framework and Details: ISO 27001 gives an ISMS its overall structure, and ISO 27002 tells you how to put certain controls into action.
Risk Assessment and Control Implementation: ISO 27001 helps businesses choose controls and do risk assessments, and ISO 27002 goes into more depth on how to put these controls into action.
Continuous Improvement: ISO 27001 stresses that the ISMS should always be getting better, and ISO 27002 gives you the exact instructions you need to make certain controls better over time.
Using ISO 27001 and ISO 27002 together in real life
These steps are usually what a company does when it chooses to use an ISMS based on ISO 27001:
Setting the Scope and the ISMS Policy (ISO 27001)
How to Evaluate and Treat Risk (ISO 27001)
Description of How It Works (ISO 27001)
Implementation of Control (using ISO 27002 as a guide)
Training and Making People Aware (ISO 27001)
How the ISMS works (ISO 27001)
Going over and checking things (ISO 27001)
Auditing the inside (ISO 27001)
A look at management (ISO 27001)
Continuous Improvement (ISO 27001 and ISO 27002 for help with making measures better)
During this process, companies can use ISO 27002 to get clear instructions on how to set up certain rules.
Case Study: The Journey of a Global Manufacturing Company
Think of GlobalTech, a global business that makes things, chose to use an ISMS built on ISO 27001 to keep its competitive edge and protect its intellectual property.
Following the steps needed by ISO 27001, they first defined the scope of their ISMS and did a full risk review. This evaluation showed that there were a lot of risks in areas like controlling who can access what, working with suppliers, and sharing information.
GlobalTech looked to ISO 27002 for detailed instructions on how to set up rules to deal with these risks. As an example:
They used ISO 27002 to help them set up a strong user authentication system and keep track of access rights for all of their global operations when it came to access control (Control A.9 in ISO 27001).
They used the suggestions in ISO 27002 to create a full supplier security strategy and set up a supplier audit program for their ties with suppliers (Control A.15 in ISO 27001).
They used ISO 27002’s advice to set up safe file transfer methods and put in place steps to stop data loss for information transfer (Control A.13 in ISO 27001).
GlobalTech was able to set up a complete ISMS that met the requirements of ISO 27001 and dealt with their unique risks by using both standards. They got ISO 27001 approval after 24 months of application and a successful audit. This shows that they are dedicated to safeguarding their intellectual property and keeping the trust of their customers and partners around the world.
Problems and Things to Think About When Putting ISO 27001 and ISO 27002 into Practice
While ISO 27001 and ISO 27002 offer a strong strategy for managing information security, companies often run into a number of problems when they try to put them into practice:
Limitations on Resources: Setting up an ISMS and the rules that go with it can take a lot of time, money, and knowledge.
Organizational mindset: Changing to a mindset that cares about security can be hard, especially in big, varied companies like GlobalTech.
Global Consistency: It can be hard for international businesses to make sure that rules are applied the same way in different countries and areas.
Technology Integration: Getting current technology systems to work with ISO 27001 and ISO 27002 standards can be hard from a technical point of view.
Regulatory Compliance: When organizations adopt ISO 27001/27002, they often have to balance this with other regulations that are relevant to their business or area.
Continuous Improvement: The ISMS needs to be maintained and changed to keep up with new threats and business needs. This takes time and money that aren’t available all the time.
How ISO 27001 and ISO 27002 Have Changed Over Time
These standards are always changing because the digital world is always changing. Some possible future trends are:
More focus on privacy settings that are in line with laws like GDPR and CCPA
More attention paid to cloud security and situations where workers are spread out
AI and machine learning being used together in security settings
Better advice on third-party risk management and supply chain security
