The demand for cloud-based offerings has surged following the uptake of hybrid working and evolving customer expectations and digital infrastructure. Businesses that fail to adapt run the risk of being left behind. Understanding the benefits to determine whether cloud adoption is right for you is therefore critical.
In our previous blogs, we shared the key advantages of cloud adoption and challenges in cloud security. In our final blog of this series, we share integral steps to strengthen your organisation’s cloud security.
As more businesses adopt cloud technology, primarily to support hybrid working, cybercriminals are focusing their tactics on exploiting vulnerable cloud environments. Over the last year, a report found that 80% of organisations experienced at least one cloud security breach.
This issue has been exacerbated by soaring global demand for tech talent. On a global scale, the demand for cybersecurity professionals reaches well into the millions, which is far beyond the current number of working individuals as is. Hiring and training new talent at pace is impossible with this accelerating demand.
It’s a vulnerable time for enterprise organisations, and cloud security is the top priority for IT leaders. Here we consider the critical steps you can take now to make your business safer.
1. Understand your shared responsibility model
Defining and establishing the split of security responsibilities between an organisation and its CSP is one of the first steps in creating a successful cloud security strategy. Taking this action will provide more precise direction for your teams and mean that your apps, security, network and compliance teams all have a say in your security approach. This helps to ensure that your security approach considers all angles.
2. Create a data governance framework
Once you’ve defined responsibilities, it’s time to set the rules. Establishing a clear data governance framework that defines who controls data assets and how data is used will provide a streamlined approach to managing and protecting information. Setting the rules is one thing, however; ensuring they’re carefully followed is another. Employing content control tools and role-based access controls to enforce this framework will help safeguard company data. Ensure your framework is built on a solid foundation by engaging your senior management early in your policy planning. With their input, influence and understanding of the importance of cloud security, you’ll be better equipped to ensure compliance across your business.
3. Opt to automate
In an increasingly hostile threat environment, in-house IT teams are under pressure to manage high numbers of security alerts. It doesn’t have to be this way though. Automating security processes such as cybersecurity monitoring, threat intelligence collection and vendor risk assessments means your team can spend less time analysing every potential threat, reducing admin errors and dedicating more time to innovation and growth activities.
4. Assess and address your knowledge gaps
Your users can either provide a strong line of defence or open the door to cyber-attacks. Make sure it’s the former by equipping staff and stakeholders access to your cloud systems with the knowledge and tools they need to conduct safe practices, such as by providing training on identifying malware and phishing emails. For more advanced users of your cloud systems, take the time to review capability and experience gaps and consider where upskilling or outsourcing is required to keep your cloud environments safe.
5. Consider adopting a Zero Trust model
Based on the principle of ‘Never Trust, Always Verify’, a Zero Trust approach removes the assumption of trust from the security architecture by requiring authentication for every action, user and device. Adopting a Zero Trust model means always assuming that there’s a breach and securing all access to systems using multi-factor authentication and least privilege. In addition to improving resilience and security posture, this approach can also benefit businesses by enhancing user experiences via Single Sign-On (SSO) enablement, allowing better collaboration between organisations and increased visibility of your user devices and services. However, not all organisations can accommodate a Zero Trust approach. Incompatibility with legacy systems, cost, disruption and vendor-lock-in must be balanced with the security advantages of Zero Trust adoption. #
6. Perform an in-depth cloud security assessment
Ultimately, the best way to bolster your cloud security is to perform a thorough cloud security audit. Having a clear view of your cloud environments, users, security capabilities and inadequacies will allow you to take the best course of action to protect your business.
7. Bolster your defences
The most crucial principle of cloud security is that it’s an ongoing process and continuous monitoring is key to keeping your cloud secure. However, in an ever-evolving threat environment, IT and infosec professionals are under increasing pressure to stay ahead of cybercriminals’ sophisticated tactics.
A robust threat monitoring solution can help ease this pressure and bolster your security defence. Threat monitoring works by continuously collecting, collating and evaluating security data from your network sensors, appliances and endpoint agents to identify patterns indicative of threats. Threat alerts are more accurate with threat monitoring analysing data alongside contextual factors such as IP addresses and URLs. Additionally, traditionally hard-to-detect threats such as unauthorised internal accounts can be identified.
Businesses can employ myriad options for threat monitoring, from data protection platforms with threat monitoring capabilities to a dedicated threat monitoring solution. However, while implementing threat monitoring is a crucial and necessary step to securing your cloud environments, IT leaders must recognise that a robust security programme comprises a multi-layered approach utilising technology, tools, people and processes.
