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.
Key Aspects of Cybersecurity
Network Security: Protects the integrity, confidentiality, and availability of data and services within a network. This involves firewalls, intrusion detection systems, and encryption.
Information Security: Safeguards data from unauthorized access, disclosure, alteration, and destruction. This includes policies, procedures, and technologies to manage data security.
Endpoint Security: Secures end-user devices such as computers, smartphones, and tablets. Anti-virus software, endpoint detection and response (EDR), and mobile device management (MDM) are common tools used.
Application Security: Ensures that software and applications usa phone number are secure by identifying and fixing vulnerabilities during development and maintenance. Techniques include code reviews, penetration testing, and secure coding practices.
Cloud Security: Protects data, applications, and services in cloud environments. This involves using cloud access security brokers (CASBs), encryption, and identity and access management (IAM).
Identity and Access Management (IAM): Manages user identities and their access to systems and data. This includes multi-factor authentication (MFA), single sign-on (SSO), and role-based access control (RBAC).
Data Security: Focuses on protecting data at rest, in transit, and in use. Encryption, tokenization, and data masking are common techniques used.
Incident Response: Involves preparing for, detecting, and responding to cyber incidents. It includes having an incident response plan, conducting regular drills, and maintaining a security operations center (SOC).
Risk Management: Identifies, assesses, and prioritizes risks to an organization's information assets. This includes conducting risk assessments, implementing mitigation strategies, and monitoring risks continuously.
Compliance and Governance: Ensures that an organization adheres to legal, regulatory, and internal policies regarding cybersecurity. This includes frameworks such as ISO 27001, NIST, GDPR, and HIPAA.
