Cybersecurity & Cyber Resilience (You need both)

Cybersecurity & Cyber Resilience (You need both)

Opinion 11 May 2023 4 minutes 654 words

Ensuring your organization’s security posture is vital and while the terms “cybersecurity” and “cyber resilience” are often used interchangeably, they represent distinct concepts in the world of IT security.

Let’s look at the high level differences between cybersecurity and cyber resilience, why both are essential, and how they complement each other in providing a comprehensive security strategy

Cybersecurity: Protecting Your Digital Assets

Cybersecurity aims to protect an organization’s digital assets, such as computer systems, networks, and data, from cyber threats. This goal is achieved through a combination of technologies, processes, and practices designed to safeguard your digital infrastructure from unauthorized access, data breaches, and cyberattacks.

The most simplistic components of cybersecurity include:

  • Access control: Implementing multi-factor authentication (MFA) and role-based access control (RBAC) systems to prevent unauthorized access to sensitive data and systems.
  • Network security: Ensuring the security of your organization’s networks by deploying firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS). For example, using tools like Snort for IDS and pfSense for firewall configurations.
  • Encryption: Protecting sensitive data with encryption algorithms like AES, RSA, and ECC, both at rest and in transit.
  • Vulnerability management: Regularly scanning for, identifying, and remediating vulnerabilities within your organization’s systems and applications. Tools like Nessus, OpenVAS, and Qualys can be used for vulnerability scanning and management.
  • Incident response: Developing a well-defined plan to detect, respond to, and recover from cybersecurity incidents. This process typically involves the use of SIEM (Security Information and Event Management) tools like Splunk, LogRhythm, and IBM QRadar.

Cyber Resilience: Ensuring Business Continuity

Cyber resilience focuses on an organization’s ability to maintain critical business functions in the face of cyber threats and recover quickly from disruptions or damages caused by such threats. It encompasses technological, organizational, and human factors, including employee training and awareness, business continuity planning, and risk management.

Your approach should contain components of cyber resilience such as:

  • Business continuity planning: Developing and maintaining a plan using Business Continuity Management (BCM) methodologies like ISO 22301, which ensures the continuous operation of critical business functions during and after a cybersecurity incident.
  • Disaster recovery: Implementing strategies and processes to restore data, systems, and operations following a cyberattack or other disruptive events. This often includes using cloud-based disaster recovery solutions like AWS Disaster Recovery, Azure Site Recovery, and Google Cloud Disaster Recovery.
  • Employee training and awareness: Conducting regular cybersecurity training and awareness programs to educate employees on the latest threats, best practices, and organizational policies. This can include training on phishing awareness, secure coding practices, and proper use of security tools.
  • Risk management: Identifying, assessing, and prioritizing risks to your organization’s digital assets, followed by the implementation of appropriate controls to mitigate those risks. Common risk management frameworks include NIST SP 800-30, FAIR, and OCTAVE.
  • Incident response: Establishing a systematic process to detect, analyze, contain, eradicate, and recover from cybersecurity incidents. This involves using tools like Jira for incident tracking and communication, and TheHive for incident response management.

Why Both Cybersecurity and Cyber Resilience are Essential

By integrating cybersecurity and cyber resilience measures, organizations can achieve a holistic security posture that not only minimizes the risk of cyberattacks but also ensures a faster recovery and business continuity in case of incidents. The synergy between these two concepts can help organizations create a more resilient and secure environment.

Key takeaways:

  1. Cybersecurity focuses on protecting digital assets, while cyber resilience emphasizes the ability to recover from cyber threats and maintain business operations.
  2. Both cybersecurity and cyber resilience are essential components of a comprehensive security strategy.
  3. Combining cybersecurity and cyber resilience can help organizations effectively address the full spectrum of cyber threats.
