Information security - what leaders need to know.

Infosec Managers

Information security discussions often get bogged down in technical jargon, especially regarding standards like ISO 27001. For leaders, it’s not about the technical details of firewalls and antivirus software; it’s about understanding what information security programs aim to achieve and how they contribute to the organisation’s success.

From a leadership perspective, ISO 27001 is about building trust—protecting your business’s critical information, reputation, and customer relationships, including customer data, financial records, and future product strategies.

Read on to clear the fog on why this standard is crucial for your organisation’s success, from a leadership point-of-view. There’s even some info on how to navigate that whole certification process that might seem daunting in this video:

Thinking beyond passwords and firewalls

Many people believe that keeping information confidential is the whole story of security, but it’s just one piece of the puzzle. Imagine making decisions based on corrupted data—this is a data integrity issue. With the rise of AI, protecting data integrity becomes even more critical to prevent data poisoning and unauthorised data extraction.

Additionally, if a critical system crashes and services are down, leading to lost revenue and unmet uptime commitments, that’s an availability issue. These scenarios highlight the importance of the CIA principles —Confidentiality, Integrity, and Availability— in a holistic approach to information security.

But how does ISO 27001 differ from just having good cyber security practices? Is it just a bunch of paperwork?

Effective information security is more than just ticking boxes; it’s about building a culture of security within your organisation. ISO 27001 provides a structured framework for managing information security across every department—not just IT.

It’s about getting everyone on board, from HR to Product, Sales, and Operations because they all handle sensitive information and play critical roles. ISO 27001 helps connect the dots to create a united front in security efforts.

“Management” means you, “system” means your organisation

ISO 27001 is a standard derived from best practices that, when implemented, should produce measurable outcomes. It doesn’t specify exactly how to achieve these outcomes but its guidance is the common language for you, auditors, and third parties to agree on what good looks like. Auditors will look for indicators that you have effective systems in place; if certain elements are missing, it’s a sign that your system may not be robust.

An Information Security Management System (ISMS) is a structured set of policies, procedures, and controls designed to manage and minimise risks to your information. It’s adaptable to your specific needs—there’s no one-size-fits-all solution. Leaders need to understand that implementing an ISMS is about building a system that evolves with your business, tailored to fit your organisation.

The key point for leaders to grasp? You’re not just implementing a rigid set of rules. You’re building a system that evolves and adapts alongside your business, tailoring it to fit your organisation.

This can be the most challenging part, however, because it takes quite a bit of experience across management, technical implementation, sales, finance, and operations to bring it together. If your organisation isn’t used to bringing all these pieces together to achieve common goals, well, it can go quite wrong.

The first step is understanding where you are and where you need to be. In the language of ISO, that’s a thorough risk assessment.

Identifying your organisation’s risks

It sounds a bit ominous, but it doesn’t have to be. While the technical aspects are important, risks extend beyond hacking attempts to any threat against the confidentiality, integrity, or availability of your information. Assessing the potential impact of each risk on your business is crucial. For example, what if a credit card expires, stopping payment for your live systems or a fire damages your main data centre? Threats can stem from natural disasters, human error, or disgruntled employees—areas where technology alone doesn’t suffice as a measure of protection.

Understanding these potential problems and their consequences allows you to prioritise efforts and allocate resources effectively. This requires input from various departments, tapping into the expertise that already exists within your organisation, and fostering a culture of security ownership.

By understanding the potential consequences, you can start to prioritise your efforts and allocate resources effectively. Again, these are management, not technical responsibilities.

Identifying all these potential risks doesn’t require you to be some kind of security fortune teller. It’s not about predicting the future, but about taking a structured approach.

You’ll need to identify your critical assets. The information that’s essential to your operations, and then analyse the potential threats to those assets. And remember, this isn’t just an IT task. You’ll need input from across the organisation. Who understands your HR processes better than your HR team? Who knows the ins and outs of your supply chain better than your operations team?

It’s about tapping into the expertise that already exists within your organisation, not relying heavily on a single information security manager that’s never used the system in question.

By involving different departments, you’re not just getting a more comprehensive view of your risks. You’re also fostering a culture of security ownership. People are more likely to take security seriously when they’ve been part of the process from the beginning.

The goal of any good information security programme is to make sure your people are able to operate on their own at the earliest opportunity, without over-reliance on outside support or bottlenecks created by scarce security resources.

Managing those risks you’ve identified

Okay, so you’ve identified your risks. Do you just cross your fingers and hope for the best? Not quite. This is where controls come in. Controls are the actions you take to manage your risks.

They can be as simple as requiring strong passwords or as complex as implementing a multi-factor authentication system. And remember those CIA principles we talked about? Your controls should be designed to address all three confidentiality, integrity and availability.

For example, let’s say you’re concerned about the risk of a disgruntled employee stealing sensitive data. You might implement access controls to limit who can access what information. And you might also put in place data loss prevention tools to monitor for suspicious activity. That’s addressing the confidentiality aspect.

To ensure data integrity, you might implement regular backups and data validation checks. To maintain availability, you might have a disaster recovery plan in place so that you can quickly restore operations if a critical system goes down.

You’re building a security safety net with multiple layers of protection.

But, really, these things are just good management. What ISO 27001 provides is a framework for creating a comprehensive and layered security program that addresses these things, gives them visibility, and makes them accessible to a third party (auditor) in a way that’s accepted by a wide range of organisations.

Certification, is it worth the cost & effort? The Benefits.

You might be asking yourself:

“Is ISO 27001 certification really worth it?”

Implementing ISO 27001 requires significant investment in time, resources, and effort, but the benefits can be substantial. Improved information security reduces the likelihood of data breaches, and the certification can enhance your reputation and provide a competitive advantage by demonstrating to customers that you take data security seriously.

There are other tangible benefits for business. It can also improve your business operations by establishing clear security processes and procedures. It demands that you have good change management procedures in place as well as that you’re tracking and monitoring goals and outcomes. This improves efficiency, reduces errors, and streamlines your compliance efforts beyond ISO 27001. Legal compliance, for instance, benefits immediately.

So, it’s not just about security for security’s sake. It’s about security enabling better business outcomes.

It also provides competitive advantages in a world where data breaches are making headlines every day. Customers are becoming increasingly concerned about the security of their information. By achieving ISO 27001 certification, you’re sending a clear message to your customers that you take data security seriously, which can be a powerful differentiator in the marketplace. In today’s competitive landscape, trust is paramount.

Ultimately, the cost of this effort can be bigger than mere cybersecurity implementation if an organisation isn’t already well-managed. You’re effectively solving many problems at once, so it helps to look at those challenges.

Getting started, not getting bogged down, & getting done

One of the biggest challenges is simply getting started. The key is to break down the implementation process into manageable steps and focus on building a solid foundation. That means working across techincal and non-techincal teams to understand where they’re at to provide them support they need during both thed ISMS design and implementation stages.

Another common challenge is resistance to change. People are often comfortable with the way things are, even if they know there’s room for improvement. Implementing ISO 27001 often requires changes to established processes and procedures, which can meet with pushback from employees. So how do you overcome that resistance and get buy-in from the entire organisation?

Communication is key. You need to clearly communicate the “why” behind ISO 27001. It’s not about creating more work for everyone. It’s about protecting the organisation and its people from harm. And it’s about building a culture of security where everyone feels empowered to identify and report potential risks. If done right, a lot of the practices that are put in place will reduce a lot of the friction and uncertainty you’re probably experiencing.

This shifts the mindset from security being someone else’s problem to it being everyone’s responsibility as well as something that helps to provide the right amount of order to a fast-moving organisation. As a leader, this means making sure your employees understand the importance of information security, their role in maintaining it, and the specific policies and procedures they need to follow. That requires ongoing education and training. It takes time.

Remember, implementing ISO 27001 is an ongoing journey, not just a destination, and you don’t have to go it alone. There are resources and experienced consultants available to guide you through the process and help tailor ISO 27001 to your specific needs. Finding the right support can make all the difference.

Thinking beyond certification

Achieving certification isn’t the end; maintaining it requires continuous compliance and improvement. Regularly reviewing and updating your risk assessments, controls, and security awareness training ensures they remain effective against evolving threats. Building a culture of adaptability keeps you ahead of potential risks.

Information security isn’t just about technology—it’s about people, processes, and culture.

Creating a security-conscious environment empowers everyone in the organisation to protect valuable information actively. While implementing ISO 27001 is a significant investment requiring careful planning, the potential benefits—improved security, reduced risk, enhanced reputation, and competitive advantage—make it a worthwhile consideration for any forward-thinking organisation.

It’s a journey that takes time, so start now.
