Cybersecurity

Cybersecurity is the defense of an organization’s computers, systems, applications, devices, networks, and data. It includes protection from internal and external threat actors attempting to steal, damage, hold hostage, and disrupt business operations and services.

Cybersecurity applies various people, processes and technologies to control and protect an organization’s digital assets and infrastructure from cyberattacks. The goal is to use best practices to reduce cyberattack risk, by protecting against and mitigating unauthorized exfiltration and exploitation of enterprise-wide digital resources and data.

Keeping up with the ever-changing threat landscape is an ongoing challenge. Cyberattacks are becoming more prevalent, sophisticated, automated and dangerous. Bad actors exploit software vulnerabilities, configuration errors, and unsuspecting users responding to social engineering tactics.

Cybersecurity technology solutions to defend against cyberattacks include capabilities like endpoint security, email security, privileged access management (PAM), zero trust networking access (ZTNA), deception technology, and more.

Cyber breach costs include the expenses incurred identifying and responding to a breach, the cost of lost productivity and revenue from downtime, and reputational damage to a business and its brand. Every organization with digital assets and resources or connectivity to the Internet is at risk. No matter their size or industry, they need cybersecurity protection.

Common cyber threats:

  • Malware - ransomware, botnet software, trojans, rootkits, spyware, viruses and worms.
  • Backdoor- a type of malware that removes pre-defined access procedures to authenticate a system.
  • Formjacking- inserts malicious code into online forms within a website.
  • Cryptojacking– hijacks computers, and installs unauthorized software to mine cryptocurrency.
  • DDoS (distributed denial-of-service) attack- floods servers, systems and networks with traffic to overwhelm and cause service disruption.
  • DNS (domain name system) poisoning attacks– exploits and compromises DNS service to cause service disruption, or redirect traffic to malicious sites.
