What is cybersecurity?

Cybersecurity is a part of information security that relates to the protection of computers, networks, programs and data against unauthorized access. As cybersecurity includes the protection of both company and personal data, the fields of cybersecurity and data protection overlap. The security objectives of confidentiality, integrity and availability are of paramount importance to both elements of information security.

Importance of cybersecurity

An essential component of every business ecosystem

As the boundaries of business continue to expand beyond the organization—with the help of accelerated digitization, increased connectivity and migration to cloud—it’s critical that security is embedded throughout your business environment. Being holistic in your approach to security gives your company the ability and confidence to scale and more agility when it comes to adapting to any future impacts. In the face of potential cyber risk, resilience is key. Companies that build security into their business ecosystems by design, rather than by adding it as an afterthought, are giving themselves the greatest opportunities to operate confidently in today’s evolving threat landscape. The security of supply chains is becoming an increasingly urgent issue for businesses. We know that as many as four in ten cyber attacks are now thought to originate in the extended supply chain, not the enterprise itself. When it comes to cloud, being secure by design is crucial. Not only does this accelerate a company’s resilience, cloud security is also important for business because it enables better outcomes. As artificial intelligence (AI) becomes a new driver of growth for organizations, attacks on AI are continuing to emerge. Frequently, cyber risks are found to be in the areas of data protection and integrity, and manipulation of algorithms. End-to-end cybersecurity, tailored to your specific business, will allow you to scale to nearly any situation and adapt to future impacts.

Cyber resilient businesses are able to operate while under persistent threats and sophisticated attacks, enabling them to embrace disruption safely, strengthen customer trust and boost shareholder value.

Types of cybersecurity

  1. Critical infrastructure security

    Concerns the protection of systems, networks and assets whose continuous operation is deemed necessary to ensure the security of a given nation, its economy, and the public’s health and/or safety. Examples include hospitals, electricity grids and traffic lights.
  2. Application security

    A set of best practices, functions and/or features added to an organization’s software to help prevent and remediate threats from cyberattacks, data breaches and other sources. Examples include antivirus programs, firewalls and encryption programs that prevent unauthorized access.
  3. Network security

    Works to act against unauthorized intrusion of internal networks. It protects the internal infrastructure by inhibiting access to it. Examples include extra logins, new passwords and monitored internet access.
  4. Cloud security

    Protects cloud platforms, services and data against unauthorized access and disruption through access management, network security and secure cloud configurations. Examples of security in cloud include encryption and disaster recovery.
  5. Internet of Things security

    Internet of Things (IoT)—networks of connected devices, appliances and machines embedded with software and sensors that can send and receive data through the internet—offers new opportunities and impressive growth potential, but it also creates new vulnerabilities. IoT security requires innovative ways of thinking to defend the enterprise and its customers against attackers and data abuses.

Cybersecurity threats

With rapidly accelerated digital transformations, opportunistic phishing campaigns, discontinuity of information security operations and financial constraints posing unprecedented challenges for businesses everywhere, security strategies and practices are being tested like never before. Cyber threat intelligence is playing a crucial role in determining the measures that organizations can put in place to outmaneuver uncertainty, emerge stronger from crises and gain greater resilience against cybersecurity threats.

Threats are widespread, they extend across industry and the public/private sector and they affect large and small businesses alike. Organizations need to strengthen defenses across people, processes, and technology.
