Cyber Security

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

Cybersecurity domains

  • Critical infrastructure security — Practices for protecting the computer systems, networks, and other assets that society relies upon for national security, economic health, and/or public safety. The National Institute of Standards and Technology (NIST) has created a cybersecurity framework to help organizations in this area, while the U.S. Department of Homeland Security (DHS) provides additional guidance.
  • Network security — Security measures for protecting a computer network from intruders, including both wired and wireless (Wi-Fi) connections.
  • Application security — Processes that help protect applications operating on-premises and in the cloud. Security should be built into applications at the design stage, with considerations for how data is handled, user authentication, etc.
  • Cloud security — Specifically, true confidential computing that encrypts cloud data at rest (in storage), in motion (as it travels to, from and within the cloud) and in use (during processing) to support customer privacy, business requirements and regulatory compliance standards.
  • Information security — Data protection measures, such as the General Data Protection Regulation or GDPR, that secure your most sensitive data from unauthorized access, exposure, or theft.
  • End-user education — Building security awareness across the organization to strengthen endpoint security. For example, users can be trained to delete suspicious email attachments, avoid using unknown USB devices, etc.
  • Disaster recovery/business continuity planning — Tools and procedures for responding to unplanned events, such as natural disasters, power outages, or cybersecurity incidents, with minimal disruption to key operations.
  • Storage security — delivers rock solid data resilience with numerous safeguards. This includes encryption and immutable and isolated data copies. These remain in the same pool so they can quickly be restored to support recovery, minimizing the impact of a cyber attack.
  • Mobile security — enables you to manage and secure your mobile workforce with app security, container app security and secure mobile mail.

Dangerous cybersecurity myths

  • Cybercriminals are outsiders. In reality, cybersecurity breaches are often the result of malicious insiders, working for themselves or in concert with outside hackers. These insiders can be a part of well-organized groups, backed by nation-states.
  • Risks are well-known. In fact, the risk surface is still expanding, with thousands of new vulnerabilities being reported in old and new applications and devices. And opportunities for human error — specifically by negligent employees or contractors who unintentionally cause a data breach — keep increasing.
  • Attack vectors are contained. Cybercriminals are finding new attack vectors all the time — including Linux systems, operational technology (OT), Internet of Things (IoT) devices, and cloud environments.
  • My industry is safe. Every industry has its share of cybersecurity risks, with cyber adversaries exploiting the necessities of communication networks within almost every government and private-sector organization. For example, ransomware attacks (see below) are targeting more sectors than ever, including local governments and non-profits, and threats on supply chains, “.gov” websites, and critical infrastructure have also increased.
