You’ve likely heard the hype around cloud computing and its ability to enhance scalability, flexibility and efficiency for businesses like yours. However, concerns around security, compliance and control often give organisations pause when it comes to moving their critical IT infrastructure and applications to a public cloud solution. What if there was a private cloud option that could give you the benefits of the cloud while still keeping your data under your ownership and management?
A tailored private cloud is the answer. By working with experienced cloud advisors and architects, you can build a custom cloud environment designed specifically for your business needs.
Let's take a closer look at how a private cloud can maximise security and give you greater peace of mind.
Securing Your Foundation
When building out a private cloud solution, the location of your hosting facilities is a crucial initial consideration. Proper datacenter selection lays the groundwork for a secure cloud deployment. Some key factors to evaluate include:
Physical Security Controls: Look for datacenters that employ strict access authorization protocols like biometric scans, mantraps and 24/7 security personnel monitoring. Environments with redundant electrical, cooling and fire suppression safeguards offer robust protection.
Geo-Political Regions: Hosting near your primary office streamlines management and supports low-latency applications. Certain regions also adhere to favourable privacy laws aligned with your compliance needs. Steer clear of jurisdictions subjected to government surveillance overreach.
Environmental Controls: Redundant power sources, generator backups and HVAC systems keep servers online and properly cooled to prevent outages. Monitoring detects changes in temperature, humidity and other metrics to proactively address issues.
Network Segmentation: The datacenter network topology should feature internal firewalls, virtual LANs and DMZ zones to partition applications and enforce precise access policies between portions of your infrastructure.
Regulatory Certifications: Prioritise facilities verified under standards like ISO 27001 for security management and HIPAA for healthcare data handling to simplify future audits.
By carefully screening hosting facilities across these criteria, you set the stage for a foundation of physical controls that enhances virtual security within your private cloud environment. Partnering with an experienced provider eases vetting numerous datacenter options.
Restricting Network Access
With a private cloud solution, you control who can gain access to your virtual environment and applications. Advanced firewalls and virtual private networking (VPN) technology allow you to whitelist approved internal and remote users while blacklisting all others. Configure security groups that tightly regulate ingress and egress rules based on your specific application port and protocol requirements.
Managing Identities and Access
Central user directories, multifactor authentication and detailed auditing logs are a must for any secure private cloud solution deployment. Granular role-based access control (RBAC) enables oversight of privileged actions while limiting individuals to only the permissions necessary for their job functions. Monitor sign-ins and resource changes to spot anomalies or suspicious activity. Regularly rotating credentials helps reduce the risk of compromised accounts.
Encrypting Sensitive Data
When storing or transmitting structured and unstructured data files, deploy proven encryption protocols to scrabble contents in transit and at rest. Leverage platform-level disc, database and file encryption features, along with your own key management policies. For selected highly sensitive information, consider tokenizing, hashing or anonymizing select fields for an added layer of protection.
Patching and Updating Regularly
Outdated or unpatched virtual servers introduce exploitable vulnerabilities for hackers. Automate critical operating system, software and system component updates on a scheduled maintenance schedule. Optionally, use vulnerability scanning and remediation tools integrated within your private cloud solution marketplace. Stay vigilant of newly disclosed product vulnerabilities and work with your provider to rapidly install urgent security fixes.
Implementing Network Segmentation
Virtual local area networks (VLANs) and micro-segmentation strategies can wall off various parts of your infrastructure and application tiers within the private cloud. Isolating functions like a database, web server and user access components into logically separate broadcast domains enhances the security posture in the event of a breach. Strict network access control lists deny the lateral movement of potential threats.
Applying Defence in Depth
Rather than relying on perimeter-based protection alone, embrace defence in depth with measures like application whitelisting, advanced endpoint protection, log inspection and malware detection integrated within your virtual machines. Multi-layered private cloud solution security makes it harder for attackers to successfully move laterally should one control be bypassed. Proactively hunt for signs of compromise across logs, traffic and system state changes.
Performing Regular DR Tests
No matter how robust your security, unforeseen disasters can strike infrastructure like fires, floods or power outages. Frequently testing your disaster recovery (DR) plan ensures continuity of business operations when needed most.
Document Recovery Procedures: Detail step-by-step instructions for failing over compute, storage and networking configurations to a backup datacenter location. Automate where possible.
Schedule Mock Drills: Conduct quarterly or biannual tests where your provider engineers simulate an actual primary site failure. Time the restore process to identify bottlenecks.
Involve Stakeholders: Include department leaders to practise their roles, plus end users to test functionality. Their feedback improves coordinated responses.
Validate Remote Access: Confirm VPNs, load balancers and other remote access tools function for teleworking if on-premise systems become unavailable.
Test Backup Integrity: Regularly restore data samples from recovery backups to verify information accuracy and ensure that restored jobs run as designed.
Leveraging Security Best Practices
Configuration reviews, code analysis, penetration testing and automated compliance assessments reinforce security through independent expert evaluation. Address findings to eliminate technical debt, close exposed vulnerabilities and confirm needed policy and procedure controls remain in place. Ongoing improvement fosters long-term resilience versus a “set it and forget it” mindset.
Developing a Suite of Monitoring Tools
A robust security information and event management (SIEM) platform ingests logs from across your infrastructure, while user and entity behaviour analytics (UEBA) detects anomalies in user actions or resource access patterns that warrant investigation. Use automation to intelligently alert on incidents, reduce noise and ensure rapid response. Visual dashboards provide real-time visibility into threats and system health.
Training Your Team on Security Awareness
Don't overlook the importance of educating all employees, including leadership, on the safety of private cloud solution technology, from detecting phishing scams to properly sanitising retired devices. Raise awareness of your security controls and policies while encouraging vigilance through a recurring training programme. After all, your organisation is only as secure as its weakest link.
Conclusion
By now, it's clear that no two businesses have identical cloud needs and risk profiles. A customised private cloud solution provides tailored tools and managed services to maximise your control over security, operations and costs. Engineer a strategic plan to fit your specific security requirements while driving efficiencies for your IT department and bottom line.
