A secure connection that encrypts internet traffic and masks a user’s IP address, providing privacy and security when accessing the internet.
23. Zero-Day Vulnerability
A security flaw that is unknown to the software vendor and has not been patched, making it particularly dangerous for exploitation.
24. Endpoint Security
Protective measures taken to secure endpoints or devices, such as laptops, smartphones, and servers, from cyber threats.
25. Data Breach
An incident where unauthorized access to sensitive data occurs, often leading to the exposure of personal or confidential information.
26. Incident Management
The process of preparing for, detecting, and responding to cybersecurity incidents to minimize impact and restore services.
27. Cybersecurity Framework
A structured approach to managing cybersecurity risks, providing guidelines and best practices for organizations.
28. Penetration Testing
A simulated cyber attack on a system or network to identify vulnerabilities and assess the effectiveness of security measures.
29. Malicious Insider
An individual within an organization who misuses their access to compromise data or systems for personal gain.
30. Risk Assessment
The process of identifying, evaluating, and prioritizing risks to an organization’s assets and operations.
31. Security Policy
A formal document that outlines an organization’s security requirements, procedures, and guidelines for protecting information assets.
32. Business Continuity Plan (BCP)
A strategy that outlines how an organization will continue operating during and after a disruptive event, including cyber incidents.
33. Disaster Recovery Plan (DRP)
A documented process for recovering and protecting a business’s critical functions after a disaster, including cyber attacks.
34. Forensics
The practice of collecting, preserving, and analyzing data to investigate cyber incidents and support legal action.
35. Threat Actor
An individual or group that engages in malicious activities targeting systems or data for financial gain, espionage, or disruption.
36. Access Token
A piece of data that authorizes a user or application to access specific resources after authentication.
37. Security Incident
An event that indicates a potential breach of security policies, leading to an unauthorized access attempt or data compromise.
38. Compliance
Adherence to laws, regulations, and standards related to data protection and cybersecurity requirements.
39. Data Loss Prevention (DLP)
Strategies and tools used to prevent unauthorized access, transfer, or loss of sensitive data.
40. Identity and Access Management (IAM)
A framework of policies and technologies for ensuring that the right individuals have access to the right resources at the right times.
41. Patch Management
The process of managing software updates and patches to fix vulnerabilities and enhance security.
42. Network Security
Measures taken to protect the integrity and usability of a network and its data from unauthorized access or attacks.
43. Security Awareness Training
Programs designed to educate employees about cybersecurity risks and best practices to help prevent security incidents.
44. Web Application Firewall (WAF)
A security solution that monitors and filters HTTP traffic to and from a web application, protecting against attacks like SQL injection and cross-site scripting.
45. Privacy Policy
A document that outlines how an organization collects, uses, and protects personal information.
