4- Zero-day Attack

A zero-day attack is exploiting a zero-day vulnerability; a zero-day vulnerability is an unknown weakness. It’s unexplained to the vendor of the target application or others who are interested in fixing it.

6- Security Risk

In simple terms, the security risk is the probability and impact of a security incident. In software security, the impact is determined by the effect of the security incident on the CIA triad.

7- Vulnerability Management

Vulnerability management is an always ongoing cycle of identifying, prioritizing, remediating software vulnerabilities. Vulnerability management is a must-have process for any organization as part of its information security program.

10- Penetration Test

A penetration test -- or pen test -- is a test for evaluating the security of the system. A pen test or ethical hacking is an authorized attack. Unlike vulnerability assessment, a penetration test tries to exploit vulnerabilities for better estimation of the risk. A penetration tester also finds the strength of the system. The results of a penetration test can be used to complete a full risk assessment.

11- OWASP

The Open Web Application Security Project (OWASP) is an online community that produces freely-available articles, methodologies, documentation, tools, and technologies in the field of web application security. The most famous project of the OWASP is the OWASP Top 10. It’s a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications.

12- ISMS

Information Security Management System (ISMS) is how an organization is managing the security of its data. It consists of processes, policies, and controls to protect overall information security. The ISO/IEC 27001 is widely known for providing requirements for ISMS.

14- Attack Surface

Attack surface or attack vector is where an attack can be started. For example, an online email subscription form on a website is an attack surface. Other examples are zero-day vulnerabilities, lack of encryption, or misconfigurations.
