What Is Cyber-Security?
Cyber-security is a broad term that encompasses all the activities required to protect computers, servers, mobile devices, electronic systems and networks from attacks and illegal access. These include data breaches, ransomware, phishing, eavesdropping and more. In a business, it includes encrypting all sensitive information and creating effective backups. It also involves installing strong passwords and two-factor authentication.
Businesses that prioritize cybersecurity benefit from building trust with their customers, leading to longer-term relationships. Moreover, they are better positioned to stay compliant with regulations, avoiding potential legal issues. They are also able to focus on their core competencies, while minimizing the impact of cybersecurity threats on operations.
Advanced cyber defense programs are necessary to protect modern-day essentials like power plants and water treatment facilities. They are likewise vital to protect personal and financial information, such as bank accounts and credit cards. These measures make it harder for attackers to steal information and exploit people financially or emotionally.
In addition to reducing the risk of these attacks, cyber security also reduces the chance that an organization will be taken down by a Distributed Denial-of-Service attack (DDoS), which floods a server or website with messages, connections and packets. The attack can be directed by individuals, groups or even whole countries. Increasingly sophisticated attacks have also appeared, including malware that eavesdrops on conversations, changes its form to avoid detection, and spreads by intercepting cellular communications or electromagnetic signals. These are known as polymorphic threats.
