Cyber Security Fundamentals: 6 Essential Steps for Your Business

Importance: Devices like printers are often overlooked entry points for cyber threats across your cybersecurity fundamentals. When left unsecured, these devices can lead to network infiltration, data leakage, and disruption of services.

Benefits:
• Minimises the device's attack surface.
• Reduces the risk of network breaches initiated through vulnerable hardware.
• Prevents unauthorised access to sensitive data stored or processed by the device.
• Mitigates potential financial losses and reputational damage from security incidents.

Importance: Simply backing up data isn't enough; backups can be corrupted, incomplete, or even contain dormant malware across your cybersecurity fundamentals. Verification ensures your backups are reliable when you need them most.

Benefits:
• Guarantees the integrity and usability of your backup data.
• Enhances overall data security by confirming backups are complete and uncompromised.
• Streamlines the disaster recovery process, minimising costly downtime and operational disruption.
• Demonstrates a proactive approach to data security, aiding regulatory compliance.

Importance: Passwords alone are vulnerable to theft and guessing within your cybersecurity fundamentals. MFA adds crucial layers of security, requiring additional proof of identity beyond just a password.

Benefits:
• Provides strong protection against unauthorised access even if passwords are compromised.
• Effectively defends against brute-force attacks attempting to guess credentials.
• Secures access for remote workforces connecting from various locations.
• Helps meet compliance requirements for data protection regulations.

Importance: Your Active Directory (AD) holds the keys to your network and is a core part of your cybersecurity fundamentals. A compromised domain gives attackers widespread access, making domain hardening essential to strengthening this critical infrastructure.

Benefits:
• Reduces the potential entry points (attack surface) for attackers targeting your domain.
• Enhances control over user access by enforcing the principle of least privilege.
• Improves the ability to detect and respond quickly to suspicious activity within the domain.
• Protects critical user accounts, permissions, and access controls.

Importance: Managing the ever-growing number of business devices (laptops, mobiles, etc.) is crucial for security and efficiency across your cybersecurity fundamentals. A comprehensive strategy is needed to secure, monitor, and control this ecosystem.

Benefits:
• Enhances security through enforced passwords, data encryption, and remote wipe capabilities for lost/stolen devices.
• Improves productivity by enabling remote application deployment and troubleshooting.
• Ensures adherence to data security regulations and compliance standards.
• Helps control IT costs through standardisation and better license management.
• Empowers employees with secure and productive remote work capabilities.

Importance: Email is a primary target for cyberattacks like phishing and Business Email Compromise (BEC), making email security essential. Traditional filters are often insufficient against modern, sophisticated threats.

Benefits:
• Protects against devastating consequences like data breaches and ransomware attacks.
• Utilises advanced techniques like sandboxing, URL rewriting, and impersonation protection (DMARC) to block malicious content.
• Prevents data loss by scanning emails for sensitive information.
• Secures email communication through encryption.

With cybersecurity fundamentals in place, organisations can progress through the next stages of a cyber security roadmap.

The next phase focuses on surveillance and continuous monitoring to detect threats early, followed by fortification to strengthen defences and protect against advanced attacks.
