ISO 27001, or the ISO/IEC 27001 in full name, is an international framework for operating information security management systems (ISMS). The International Organization for Standardization (ISO) released it in cooperation with the International Electrotechnical Commission (IEC) to provide businesses with information security guidelines.
The FBI Internet Crime Report 2023 reveals an alarming 22% increase in cybercrime losses, potentially exceeding $12.5 billion. A significant portion of cyberattacks are directed at businesses that should implement the ISO 27001 framework to assess the risks, mitigate damages, and adhere to international data security standards.
Getting ISO 27001 compliance ensures customer and brand reputation safety, but where to start? In this article, I'll elaborate on the meaning of ISO 27001 for business information safety and how cybersecurity services like CyberUpgrade assist with reaching the ISO 27001 standard.
What is ISO 27001 compliance?
ISO 27001 compliance means that the business adheres to the recommended ISO framework for information safety. It is worth noting that ISO does not issue compliance certificates, so enterprises must acquire the ISO 27001 information security proof from an authorized third party. Such specialists evaluate information security management system implementation company-wide and issue a compliance certificate after a successful audit.
Meeting ISO 27001 requirements is a multi-step and ongoing process. Businesses that want to remain compliant must repeatedly undergo independent third-party audits that will evaluate contemporary risks and readiness. Preparing for this audit is challenging as comprehensive ISMS must identify all vulnerabilities, from software bugs to employee security awareness.
Businesses can get professional assistance to prepare for the ISO 27001 compliance audit. Services like CyberUpgrade provide legal, cybersecurity, compliance, and software testing advice to identify weak points and patch them up. Small-to-medium enterprises without a dedicated workplace security team should seek outside help to implement the ISO information security framework. CyberUpgrade handles 95% of the tasks for you.
Getting ISO 27001 compliant takes a lot of time and effort across your whole organization. Use CyberUpgrade to get ISO 27001 compliance in 2 months. You'll get a powerful compliance platform + a dedicated team of experienced CISOs.
Why is ISO 27001 important?
The importance of the ISO 27001 framework is twofold. First, the increasing cybercrime against businesses demands organized ISMS for protection. This standard helps identify possible computer network vulnerabilities and attack scenarios, prepare for them, and assess and mitigate the risks. At the same time, adherence to ISO 27001 helps meet other regulatory compliance requirements, such as GDPR, HIPAA, or NIST cybersecurity framework.
Just as significant are consumer-centric benefits. Customers who trust a business with their digital data expect it to remain safe. For example, major Marriott hotel data leaks significantly damaged its brand and resulted in a fine of £18.4 million to compensate for the careless management of personal customer data.
What are the principles of ISO 27001?
ISO simplifies its operational scope using confidentiality, integrity, and availability (CIA) principles. So, what is the ISO 27001 CIA principle? Let's go over each.
| 🤫 Confidentiality |
| It ensures that only authorized parties can access business information. Confidentiality protects sensitive user data from data leaks, rogue employees, and other unauthorized disclosure. |
| 🔑 Integrity |
| This principle safeguards information from tampering. Integrity means stored data is complete, accurate, and not modified, including virus infections and accidental deletions. |
| 🖥️ Availability |
| Stored data must be available to authorized parties at all times. It means there should be backups to mitigate downtime, denial of service attack protection, and recovery from natural disaster plans. |
Benefits of ISO 27001
I will categorize the essential ISO 27001 benefits into four groups for a broader perspective.
- Comprehensive cybersecurity. The ISO 27001 framework issues clear steps to establish, monitor, and continuously improve enterprise ISMS. Its broad focus secures weak points in software code, gaps in employee security awareness, and physical business information safety and outlines a quick incident response plan.
- Legal requirements compliance. The European General Data Protection Regulation (GDPR) came into effect in 2018, so it is still relatively new and unfamiliar to many businesses. Similar regulations appeared later, like the California Consumer Privacy Act (CCPA) in 2020 and the Colorado Privacy Law in 2023. Following the ISO/IEC 27001 instructions, businesses can implement required safety procedures to meet international data safety laws.
- Mitigate cybercrime costs. Successful cyber-attacks are extremely costly, going into tens of millions for large enterprises, and the negative impact can bankrupt smaller companies without the resources to deal with the crisis. ISO 27001 significantly reduces the chances of getting hacked, which, in turn, protects the brand's reputation.
- Remain competitive. Cybercriminals look for the easiest target with the biggest returns. Enterprises with elaborate cybersecurity systems are hard to breach and will suffer fewer and less costly cyber incidents. Meanwhile, less-secured companies can expect production outages, consumer data leaks, and ransomware attacks. The ISO/IEC 27001 compliance badge conveys a message of security and responsibility, thus also securing a competitive advantage.
How does ISO 27001 work?
The objective of ISO 27001 is to guarantee the confidentiality, integrity, and availability of business data. Remember that the exact framework implementation depends on business structure and demands but follows the same general logic.
ISO 27001 begins with the initial assessment of company structure, business relations (partners, stakeholders, etc), security gap identification, and ISMS plan development. Then, clear goals are set, and responsibilities are distributed to put them in motion. A more elaborate risk assessment identifies exact vulnerabilities and potential threats and ranks them according to risk severity.
Then, ISMS control mechanisms are placed to secure weak points, starting with the most risky scenarios. The team responsible issues procedural documents for maintaining the security system, including incident response and continual improvement guidelines for the future. Lastly, the ISMS is reviewed regarding overall effectiveness, and an optional but highly beneficial compliance audit finalizes the process.
How to prepare for ISO 27001 certification?
Getting the ISO 27001 cybersecurity compliance certificate is advantageous, as outlined in the previous chapters. But this challenging task requires deploying 93 controls grouped in 4 sections, so even an experienced CISO (Chief information security officer) will have their hands full during the process.
One solution is to seek professional assistance, like business-to-business software-as-a-service (B2B SaaS) help from CyberUpgrade. The cybersecurity and legal experts there will analyze your company organization, security gaps, and other requirements for ISO 27001 compliance.
But that doesn't mean you cannot do it yourself. If you have the time, dedication, and knowledge to navigate through the complex cybersecurity language, you will start here to meet strict ISO 27001 requirements.
How many controls are in ISO 27001?
The latest ISO 27001 version was released in 2022 and includes 93 controls organized in 4 sections. Not all businesses must implement all 93 controls, but they should aim at this number to secure all vulnerabilities.
| ⚙️ Organizational controls |
| These are company-wide rules that must be followed to adhere to ISO 27001 requirements. Employees must be introduced to business cybersecurity policies, responsibilities distributed across relevant teams, and human resources instructed regarding safe onboarding and offboarding flow. In other words, the business organization structure is set up according to ISO 27001 recommendations. |
| 👱 People controls |
| Human error is the leading cause of cybersecurity accidents. After all, it is easier to deceive unaware employees than to break a sophisticated firewall. Businesses must order regular cybersecurity awareness training to keep employees up to date regarding the latest risks and safety practices. Simultaneously, HR must perform employee background checks, and information security specialists monitor suspicious activities to prevent insider threats. |
| 📋 Physical controls |
| These controls encompass physical access to data storage facilities and response to environmental disasters. The former ensures that only authorized employees can access server or security personnel rooms and that surveillance cameras and doors have access control systems. Meanwhile, the latter ensures server and data center safety during fires, floods, hurricanes, and all other environmental hazards characteristic of the region |
| 💻 Technological controls |
| The ISO 27001 technological controls section recommends hardware and software solutions to ensure information safety. It includes encryption software, an antivirus, a firewall (and additional intrusion detection systems if required), and a backup system. |
Conclusion
The general principles of ISO 27001 are easy to understand, which makes this international data security standard so widespread. However, meeting its strict demands is a challenging task that requires cybersecurity know-how, cross-team collaboration, and a company-wide policy for the foreseeable future.
Businesses that undergo this lengthy procedure have a significant competitive advantage. Not only do they prevent and reduce financial losses and brand reputation damage, they convey an aura of safety and responsibility to the customers. After so many data leaks, internet users are becoming more and more aware of cybersecurity's importance.
The guidelines in this article outline the essential steps businesses should take for ISO 27001 compliance. However, I also recommend checking out services like CyberUpgrade that help navigate the complex landscape of data security, legality, and adherence to international lawful standards. One way or another, this framework is an outstanding defense strategy against evolving cybercrime adversaries.
