Cyber security refers to the practice of protecting systems, networks, and data from digital attacks. These attacks are often aimed at accessing, changing, or destroying sensitive information, extorting money from users via ransomware, or interrupting normal business operations.
It encompasses various measures including network security, application security, endpoint protection, data security, identity management, and disaster recovery. Implementing a comprehensive cyber security strategy involves a layered defense that includes both technology and human factors.
Common tools and practices include firewalls, antivirus software, intrusion detection systems (IDS), multifactor authentication (MFA), and regular security audits. Organizations must also foster a security-aware culture among employees to mitigate risks such as phishing or social engineering.
Cyber threats are constantly evolving, making it essential for businesses to remain vigilant and up-to-date with the latest defenses. Cyber security also involves regulatory compliance, such as GDPR, HIPAA, or PCI-DSS, depending on the industry.
An effective cyber security program safeguards an organization's assets, builds customer trust, and maintains business continuity in the face of ever-increasing cyber risks.
