Endpoint Security: Securing individual devices such as computers, smartphones, and tablets from malware and other threats Application Security: Ensuring that software and applications are developed and used securely, which includes regular patching and vulnerability assessments. Data Security: Protecting sensitive data through encryption and access controls, as well as ensuring data backup and recovery measures are in place. Security Awareness and Training: Educating employees and users about cybersecurity best practices and potential threats to reduce human error. Incident Response: Developing plans and processes to address and mitigate security breaches when they occur. Security Assessment and Auditing: Regularly testing and assessing the security of systems and networks to identify vulnerabilities and weaknesses. Compliance and Regulation: Adhering to industry-specific regulations and legal requirements related to data protection and privacy. Cloud Security: Ensuring the security of data and applications hosted in cloud environments, such as Amazon Web Services (AWS) and Microsoft Azure.
