In today’s digital landscape, robust cybersecurity is no longer an afterthought; it’s a fundamental pillar for achieving technological success. The need for cyber resilience extends to all businesses, regardless of size in order to foster an environment that facilitates innovation and empowers a productive workforce.
Statistics paint a concerning picture: a staggering 80% of security incidents can be prevented with basic security practices, and a whopping 90% of compromised accounts lacked strong authentication. Basic security measures are a crucial first step, but navigating the complexities of cyber resilience requires a strategic plan, and for many organisations, partnering with a managed cyber security services provider can be a powerful solution.
This blog post dives deep into Microsoft’s insights on building cyber resilience. We’ll explore 5 key strategies to achieve robust security, followed by a look at Microsoft’s security solutions and methods for fostering a culture of cyber awareness within your organisation.
What is Cyber Resilience?
Cyber resilience is the capability of an organisation to prepare for, withstand, and recover from cyberattacks while ensuring the continuity of critical business operations and the availability of sensitive data.
Building Cyber Resilience: 5 Strategies for Robust Security
Building cyber resilience requires a proactive, multi-layered approach that strengthens your organisation’s defences from the ground up. Here are five key strategies to achieve robust security:
- Enforce Phishing-Resistant Multi-Factor Authentication (MFA)
- Embrace Zero Trust Principles
- Deploy Modern Anti-Malware
- Maintain Up-to-Date Systems
- Prioritise Data Protection
1. Enforce Phishing-Resistant Multi-Factor Authentication (MFA)
MFA adds an extra layer of security, making it significantly harder for attackers to gain unauthorised access, even if they steal credentials. Phishing-resistant MFA utilises biometrics or security tokens, further thwarting phishing attempts.
Here’s a breakdown of common phishing attacks to be aware of:
- Email Phishing: Fraudulent emails are designed to appear legitimate, often mimicking trusted senders like banks, tech companies, or even colleagues. These emails may contain malicious links or attachments that compromise your security upon interaction.
- Content Injection: Attackers can manipulate legitimate websites to inject malicious code. This code can then steal user credentials or redirect them to phishing landing pages disguised as real websites.
- Link Manipulation: Deceptive tactics involve altering legitimate links to appear harmless. When clicked, these links can lead to phishing websites designed to steal your information. Shortened URLs are a common way for attackers to mask malicious destinations.
- Spear Phishing: This targeted approach involves crafting personalised emails that exploit the recipient’s specific information or interests. Attackers might use readily available personal details gleaned from social media to make the email appear more believable.
- Man-in-the-Middle (MitM): Attackers can intercept communication channels between a user and a website. By positioning themselves in the “middle,” they can potentially steal sensitive information transmitted, such as login credentials or credit card details.
2. Embrace Zero Trust Principles
Zero Trust is a security framework that assumes no user or device is inherently trustworthy. It requires continuous verification throughout a session, minimising potential damage from breaches by limiting access to authorised resources only.
Why a Zero Trust approach works:
- It empowers a flexible workforce: Zero Trust facilitates secure remote and hybrid working models, allowing authorised users to access resources seamlessly regardless of location.
- It minimises breach impact: By constantly verifying access, Zero Trust helps contain breaches, minimising potential damage to your business operations.
- It safeguards sensitive data: Zero Trust prioritises the identification and protection of critical business data and identities, reducing the risk of unauthorised access.
- It inspires confidence in security: The continuous verification inherent to Zero Trust builds trust and transparency in your security posture across all stakeholders.
3. Deploy Modern Anti-Malware
Modern anti-malware software acts as a critical line of defence against malicious programs and viruses. These solutions offer real-time protection, continuously scanning for and blocking new threats.
Security automation best practices to follow:
- Offload to Detectors: Shift tasks to detection tools. Sensors should analyse, correlate, and link findings before needing analysts.
- Prioritise Security Events: Leverage real-time analytics to elevate the most critical security events based on severity and threat intelligence, ensuring analysts address the most pressing issues.
- Automate Tasks: Automate common, repetitive tasks first. Standardise response to streamline analyst workflow and free them for strategic work.
- Continuously Improve: Monitor key metrics and adapt sensors and workflows for ongoing optimisation.
4. Maintain Up-to-Date Systems
Outdated software and operating systems often contain vulnerabilities that attackers can exploit. Regularly patching and updating systems significantly reduces your attack surface and strengthens your overall security posture.
Consider these guiding principles to bolster your IoT/OT security:
- Secure and Harden Devices: Apply security patches promptly, change default passwords and ports, and restrict remote access by blocking unnecessary ports and utilising VPNs.
- Minimise Attack Surface: Eliminate unnecessary internet connections and open ports. Segment networks to isolate critical systems (IoT, OT) from corporate IT networks using firewalls. Ensure critical protocols (e.g., ICS) are not directly exposed to the internet.
- Enhance Monitoring and Visibility: Implement IoT/OT-aware NDR/SIEM/SOAR solutions to detect anomalous behaviour. Gain deep visibility into connected devices and prioritise them based on security risk. Utilise firmware scanning tools to identify vulnerabilities and collaborate with vendors for mitigation.
- Implement Proactive Threat Management: Positively influence vendor practices by requiring secure development lifecycles for IoT/OT devices. Proactively conduct incident response exercises for OT networks. Deploy continuous monitoring solutions like Microsoft Defender for IoT.
5. Prioritise Data Protection
Data is an organisation’s lifeblood. Implementing robust data security measures, such as encryption and access controls, is essential to safeguard sensitive information from unauthorised access, loss, or misuse.
Why a defence-in-depth approach works:
- See All, Secure All: Gain complete visibility into your data (location & access) to identify weaknesses and implement targeted protection for sensitive information.
- Smarter Security: Leverage data classification to understand usage patterns. This allows for granular access controls and monitoring, preventing unauthorised access and leaks.
- Proactive Threat Defence: Go beyond external threats. This approach considers user behaviour and potential security incidents to implement user training, access controls, and security tools, mitigating insider risks before they happen.
- Stop Data Loss, Not Productivity: DLP solutions prevent unauthorised data loss while maintaining user productivity. Control access and data usage through policies to stop actions like unauthorised data storage or printing.
- Empowered Governance, Secure Future: Empower business teams to manage their data responsibly. This unified approach to data lifecycle management enhances security and fosters responsible data usage for better decision-making.
