Modern attacks are becoming increasingly complex; and thus, for a Security Officer to remain proactive is important. These attacks may include zero-day attacks, which target unknown vulnerabilities before the development of their patches; Advanced Persistent Threats (APTs), which stealthily break into networks to extract crucial information; and then there are threats posed by ransomware attacks and spear phishing attacks, which may compromise users to grant attackers their accesses and passwords.

To counter these kind of attacks, the SO can use the following multi-layer security measures: It is essential to keep the systems updated, install firewalls and an IDS, enforce strict access control by practicing the principle of least privilege, and finally, enforce Multi-Factor Authentication (MFA). Monitoring and the process of hunt in the organization will enable the SO to detect abnormal behavior early on, and education of the employees on phishing and best practices will minimize human-related vulnerabilities.
