Zero-click exploits present a complex challenge for chief information security officers (CISOs). Their silent and seamless nature makes detection and prevention difficult. Yet, given the severe consequences of successful zero-click exploitation, ranging from intellectual property theft to operational disruption, it is critical for CISOs to stay informed and proactive in their security strategies.
Enter the Information Security Analyst (ISA) — a key figure in an organisation’s defence against cyber threats. Far from being just another IT role, an ISA is pivotal to safeguarding sensitive information, ensuring compliance, and maintaining business continuity. This article explores the role of an Information Security Analyst and provides a detailed examination of why C-level executives must prioritise information security within their organisations.
Before delving into vulnerabilities, it’s essential to establish what firewalls do. In essence, a firewall is a security device—either hardware, software, or a combination of both—that monitors and controls incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and untrusted external networks, such as the Internet. Firewalls use a set of predefined security rules to filter traffic, allowing legitimate connections while blocking potentially harmful ones.
Vulnerability management is the proactive process of identifying, assessing, and mitigating vulnerabilities within an organisation’s IT infrastructure. It involves a systematic approach to discovering and addressing weaknesses that malicious actors could exploit.
