Cyber security is the practice of defending networks, systems and programs from malicious attacks that increasingly occur in the digital world. Businesses that integrate cybersecurity into their overall business strategies can help reduce the risk of such attacks, which can have severe financial and reputational consequences.
Threat actors employ a wide range of tactics to steal information or disrupt an organization’s technology and services. For example, in a targeted attack, bad actors might use tools such as domain name system tunneling, distributed denial-of-service (DDoS) attacks or man-in-the-middle attacks to break into a company’s network. Or, in a mass-mailing attack, attackers might send emails to people that include socially engineered links designed to entice them to click and download malware. Attackers also develop and share software tools to facilitate their illegal activities on the dark web, which can be used by anyone with access.
Most of the threats are driven by criminal motivations such as theft, disruption and revenge. Attackers often target government entities, but attacks can also hit businesses or nonprofits. And, because critical infrastructure sectors, like energy production and transmission, water and wastewater, and healthcare, are interconnected, a cyberattack on one sector can affect others.
To effectively protect against these and other types of threats, companies need to conduct a risk assessment and establish clear security policies and procedures. Regularly reviewing and updating these policies based on changing technology, threats and the business environment is important. Educating employees about the importance of cybersecurity and providing them with training on best practices can also help minimize risk. Security Operations Center
