Incident Response refers to the actions taken to address and manage the aftermath of a security breach or attack. Automated incident response systems can quickly identify and respond to incidents, minimising damage and recovery time.
11. Threat Intelligence
Threat Intelligence involves collecting and analysing information about threats and threat actors to understand their capabilities, intentions, and attack vectors. Automated threat intelligence platforms gather data from various sources, analyse trends, and provide actionable insights.
12. Multi-Factor Authentication (MFA)
MFA is a security system that requires multiple forms of verification to access a system. Automation can streamline the MFA process, making it more user-friendly while maintaining high security.
13. Encryption
Encryption is the process of converting data into a code to prevent unauthorised access. Automated encryption tools ensure that data is encrypted and decrypted efficiently, protecting sensitive information.
14. Zero Trust Security
Zero Trust Security is a security model that assumes no entity, whether inside or outside the network, can be trusted. Automation helps enforce Zero Trust principles by continuously verifying users and devices.
15. Security Orchestration, Automation, and Response (SOAR)
SOAR platforms integrate security tools and processes to automate incident response, threat hunting, and security operations. These platforms enhance the efficiency and effectiveness of security operations.
