NYOXA LABS

Security terms explained in client-friendly language.

A plain-language reference for terms that appear in NYOXA LABS reports and assessment discussions.

Authorization

Assessment & Testing

Written, formal approval required before any security testing can legally begin. It defines the specific systems that can be tested.

Why it matters / Example

Before testing your API, NYOXA LABS requires a signed Rules of Engagement document containing authorization.

Scope

Assessment & Testing

The exact boundaries of a security assessment, detailing which IP addresses, domains, APIs, and actions are permitted for testing, and which are strictly off-limits.

Why it matters / Example

The scope for the test included 'api.example.com' but explicitly excluded the third-party payment gateway.

Rules of Engagement (RoE)

Assessment & Testing

A document outlining the conditions under which a penetration test will be conducted, including testing windows, communication protocols, and emergency contacts.

Why it matters / Example

The RoE specified that testing could only occur between 9 PM and 5 AM EST to minimize impact on real users.

Evidence

Assessment & Testing

Screenshots, network requests, responses, and behavioral observations collected during a test to definitively prove a vulnerability exists.

Why it matters / Example

The final report included evidence showing the raw HTTP request used to bypass the login screen.

Remediation

Assessment & Testing

The process of fixing a vulnerability or implementing a security control to reduce the identified risk to an acceptable level.

Why it matters / Example

The recommended remediation for the SQL injection was to use prepared statements in all database queries.

Retesting

Assessment & Testing

A follow-up validation step performed after a client has applied fixes, aimed at confirming whether the vulnerabilities were successfully resolved.

Why it matters / Example

After the engineering team patched the servers, NYOXA LABS performed retesting and confirmed the critical findings were closed.

Penetration Testing (Pentest)

Assessment & Testing

A simulated cyberattack against your computer system to check for exploitable vulnerabilities, using the same tools and techniques as real attackers.

Why it matters / Example

The penetration testing exercise revealed that an attacker could chain three minor flaws together to gain full admin access.

Vulnerability Scanning

Assessment & Testing

The automated process of proactively identifying network, application, and security vulnerabilities without necessarily attempting to exploit them.

Why it matters / Example

Vulnerability scanning found outdated software, but a manual pentest was needed to prove the data could actually be stolen.

Authentication

Security Mechanisms

The process of verifying the identity of a user, device, or system. It answers the question: 'Are you who you say you are?'

Why it matters / Example

Requiring a password and a code sent to a mobile device (MFA) is a strong form of authentication.

Authorization (Access Control)

Security Mechanisms

The process of determining what an authenticated user or system is allowed to do. It answers the question: 'Are you allowed to do this?'

Why it matters / Example

The user successfully logged in (Authentication), but the system denied them access to the billing dashboard (Authorization).

Principle of Least Privilege

Security Mechanisms

The security concept of giving a user account or process only those privileges which are essential to perform its intended function.

Why it matters / Example

Following the principle of least privilege, the marketing team's database credentials only allow read access, not write access.

Defense in Depth

Security Mechanisms

An approach to cybersecurity in which a series of defensive mechanisms are layered to protect valuable data and information.

Why it matters / Example

Using a firewall, strong passwords, MFA, and encrypting the database at rest are examples of defense in depth.

Encryption

Security Mechanisms

The process of converting readable data into an unreadable format using an algorithm and a key, preventing unauthorized access during storage or transit.

Why it matters / Example

TLS encryption ensures that credit card numbers sent from the browser to the server cannot be intercepted by attackers on the network.

Attack Surface

Vulnerabilities & Attacks

The total sum of vulnerabilities, pathways, or methods that an attacker can use to enter a system or extract data.

Why it matters / Example

Closing unused network ports and disabling old subdomains significantly reduced the company's external attack surface.

Broken Access Control

Vulnerabilities & Attacks

A security failure where users can act outside of their intended permissions, leading to unauthorized information disclosure, modification, or destruction.

Why it matters / Example

Broken access control allowed a standard user to view the private settings page of an administrator.

Insecure Direct Object Reference (IDOR / BOLA)

Vulnerabilities & Attacks

A specific type of broken access control where an application uses client-provided input to access objects directly without proper authorization checks.

Why it matters / Example

By changing the URL from `user_id=12` to `user_id=13`, the attacker exploited an IDOR to view another customer's invoice.

Cross-Site Scripting (XSS)

Vulnerabilities & Attacks

A vulnerability where an application includes untrusted data in a web page without proper validation or escaping, allowing attackers to execute malicious scripts in the victim's browser.

Why it matters / Example

An attacker exploited an XSS flaw by posting a malicious script in a blog comment, which then stole the session cookies of anyone who read the post.

SQL Injection (SQLi)

Vulnerabilities & Attacks

An injection attack that makes it possible to execute malicious SQL statements, allowing an attacker to view, modify, or delete data in a database.

Why it matters / Example

Using SQL injection on the login page, the attacker bypassed authentication by forcing the database to evaluate a query as logically true.

Social Engineering

Vulnerabilities & Attacks

The psychological manipulation of people into performing actions or divulging confidential information.

Why it matters / Example

The attacker used social engineering by calling the helpdesk pretending to be the CEO in order to get a password reset.

Phishing

Vulnerabilities & Attacks

A type of social engineering attack often used to steal user data, including login credentials and credit card numbers, by masquerading as a trusted entity via email or text.

Why it matters / Example

The employee received a phishing email that looked exactly like a Google login prompt, tricking them into entering their password.

Zero-Day Vulnerability

Vulnerabilities & Attacks

A previously unknown vulnerability in a software or system that attackers can exploit before the software vendor has created a patch.

Why it matters / Example

The firewall was compromised using a zero-day exploit, meaning the IT team had no way of patching it beforehand.
