Cyber Security Lessons from Recent Attacks: Why ISO 27001 Matters More Than Ever
In recent weeks, two of the UK’s most recognisable brands – found themselves the victims of major cyber attacks. These incidents are a wake-up call for all businesses, large or small, to reassess their computer security measures and ensure they’re not the next headline.
The Impact of Cyber Attacks
A company suffered a ransomware attack that disrupted parts of its online operations and raised concerns over data exposure. Around the same time, another company confirmed a breach through its payroll provider, linked to the ongoing exploitation of the file transfer tools. Employee data was potentially compromised, revealing a worrying weakness in third-party risk management.
These attacks have once again highlighted how phishing emails, unpatched systems, and weak supply chain controls can lead to serious business disruption and reputational damage.
ISO 27001: A Structured Approach to Cyber Security
The attacks underline the importance of implementing a formal cyber security framework – and ISO 27001 is the global gold standard.
ISO 27001 helps businesses establish, implement, maintain, and continuously improve an Information Security Management System (ISMS). It ensures risks are assessed methodically, controls are in place, and internal awareness is high – something that could help mitigate the kind of damage companies can experience.
Practical Steps to Strengthen Computer Security
Achieving ISO 27001 isn’t just about certification – it’s about embedding computer security into every level of the organisation. Here are a few critical steps companies should take:
Train staff to spot phishing attempts
Many breaches begin with a simple, deceptive email. Regular, engaging training or cyber security courses can reduce human error.
Use a secure passwords manager
Weak or reused passwords remain one of the biggest risks. A reliable passwords manager can help enforce strong, unique credentials.
Review and test incident response plans
Know what to do when a breach occurs. Being prepared can reduce downtime and limit data loss.
Audit third-party providers
As seen with Co-op, vendors can be a major vulnerability. ISO 27001 requires ongoing supplier risk assessments.
Why Businesses Need to Act Now
Cyber threats are evolving, and so must the response. The recent incidents prove that even established, trusted brands can fall victim. Implementing ISO 27001 and investing in cyber resilience – from passwords managers to cyber security courses – isn’t optional; it’s essential.
Your reputation, your customer trust, and your bottom line depend on it.
If you’re considering ISO 27001 certification or want to strengthen your cyber security posture, now is the time to take action. Waiting until after an attack is too late.
