Glossary of cyber threat terms

1. Advanced Persistent Threat (APT)
   An Advanced Persistent Threat (APT) is a highly skilled, stealthy cyber attack, often orchestrated by nation-states or organized crime groups, targeting large organizations, government agencies, or critical infrastructure. APTs focus on maintaining long-term access to a system rather than immediate impact, enabling continuous data exfiltration or network control over months or years. APT attacks often use sophisticated tools and techniques, including custom malware, social engineering, and zero-day vulnerabilities, and are characterized by extensive planning, reconnaissance, and resources. NVIS AI mitigates APT risks by enforcing continuous authentication through a Zero Trust model, ensuring that even the most skilled threat actors cannot access sensitive systems undetected.

2. Botnet
   A botnet is a network of compromised devices, such as computers or IoT devices, controlled remotely by a cybercriminal. Often created by infecting devices with malware, botnets can be commanded to perform coordinated attacks, such as Distributed Denial of Service (DDoS) campaigns, spam campaigns, or cryptojacking operations. Botnets are challenging to detect because they use multiple devices to mask the source of the attack. NVIS AI’s continuous monitoring and peer-to-peer communication model make it more difficult for botnets to integrate into or exploit the network, as it isolates potentially infected devices and prevents malware from spreading.

3. Distributed Denial of Service (DDoS)
   DDoS attacks aim to overwhelm servers or networks by sending massive volumes of traffic from multiple sources simultaneously, disrupting or denying service to legitimate users. Botnets often facilitate DDoS attacks by amplifying traffic from multiple infected devices. DDoS attacks can disrupt operations, harm customer trust, and even lead to financial loss. NVIS AI’s decentralized architecture distributes data requests across multiple nodes, mitigating the impact of DDoS attacks by balancing the load and maintaining service continuity.

4. Layer 2 encryption
   Layer 2 encryption secures data directly on the data link layer (Layer 2) of the OSI model, allowing for private communication between network devices. Unlike higher-layer encryption, which focuses on application-level data, Layer 2 encryption secures the data paths, effectively preventing interception and tampering by external actors. NVIS AI employs Layer 2 encryption to ensure that even if attackers manage to access part of the network, they cannot decrypt or tamper with the data in transit, adding an essential layer of security.

5. Person-in-the-Middle (PITM)
   In a Person-in-the-Middle (PITM) attack, a cybercriminal intercepts communication between two parties, usually without their knowledge. This position allows the attacker to monitor, modify, or steal information. PITM attacks can take various forms, including Wi-Fi eavesdropping, SSL hijacking, and phishing tactics. NVIS AI counters PITM attacks by enforcing peer-to-peer, end-to-end encryption, ensuring data remains private and secure even if a threat actor attempts to intercept the communication.

6. Phishing
   Phishing is a social engineering tactic where cybercriminals disguise themselves as trustworthy entities to deceive users into sharing sensitive information like login credentials or financial details. Phishing often involves mass-distributed emails with links to fraudulent websites designed to look legitimate. Variants like spear-phishing and whaling target specific individuals or high-profile executives with personalized content to increase success. NVIS AI mitigates phishing risks by integrating stringent access controls and monitoring, ensuring that even compromised credentials cannot access secure systems without additional verification.

7. Ransomware
   Ransomware is malicious software that encrypts files or locks users out of their systems until a ransom is paid to the attackers. This extortion technique targets individuals, corporations, and government agencies alike, often resulting in operational disruptions and significant financial loss. “Big Game Hunting” ransomware campaigns target large enterprises willing to pay substantial ransoms to regain control. NVIS AI’s Zero Trust architecture limits ransomware’s ability to spread by controlling access permissions and isolating compromised systems, effectively containing threats within a secured boundary.

8. Social engineering
   Social engineering is a psychological manipulation tactic where attackers exploit human emotions like trust, curiosity, or fear to gain unauthorized access to systems. This tactic includes phishing, spear-phishing, and impersonation attacks, where threat actors manipulate victims into providing sensitive information or access. NVIS AI mitigates social engineering risks by enforcing rigorous authentication checks, requiring multiple verification factors, and ensuring that sensitive information is only accessible to verified users.

9. Zero Trust architecture
   Zero Trust Architecture is a security framework based on the principle of “never trust, always verify.” Rather than assuming trust for users within a network, Zero Trust requires verification at every access point, device, and user interaction. Each user or device must authenticate and continuously prove compliance before accessing secure data. NVIS AI leverages Zero Trust principles to protect sensitive resources by implementing real-time, dynamic access verification, thus preventing unauthorized access from both external attackers and insider threats.

10. Exploits and zero-day exploits
    An exploit is a piece of malicious code or technique that leverages known vulnerabilities to gain unauthorized access, manipulate systems, or deploy additional malware. Zero-day exploits target previously unknown vulnerabilities that have no patches or mitigation solutions, making them particularly dangerous as they’re invisible to traditional defenses. NVIS AI mitigates exploits by monitoring network traffic, identifying irregular patterns, and enforcing strict access protocols, limiting the spread of vulnerabilities within the system.

11. Social media manipulation and online influence
    Threat actors use online influence campaigns, misinformation, and disinformation to manipulate public opinion, interfere with elections, or harm reputations. Through targeted campaigns on social media and fake news, attackers seek to disrupt social cohesion or influence behavior. NVIS AI’s secure, private communication model limits unauthorized access to systems and data, mitigating the impact of influence campaigns on secure communication platforms.

12. Immutable blockchain-based audits
    Immutable blockchain-based audits create tamper-proof logs of all network activity, ensuring that each action is recorded securely and cannot be altered. This transparency offers valuable forensic evidence and helps organizations meet regulatory requirements. NVIS AI uses blockchain technology to log each interaction within the network, providing an indisputable, transparent trail of all activity to aid compliance and investigation if a breach occurs.

13. Wi-Fi eavesdropping
    Wi-Fi eavesdropping occurs when a threat actor intercepts unencrypted communications over unsecured networks, capturing sensitive information like login credentials, financial data, or personal details. Attackers can set up rogue Wi-Fi hotspots to trick users into connecting, making them susceptible to data theft. NVIS AI prevents Wi-Fi eavesdropping by encrypting all network communications and directing data through secure, private channels.

14. Credential stuffing and brute force attacks
    Credential stuffing involves using stolen username-password pairs from previous breaches to gain unauthorized access, while brute force attacks use repeated password attempts to break into an account. Both methods rely on weak or reused credentials for success. NVIS AI’s Zero Trust framework continuously verifies users based on multiple factors beyond just passwords, reducing the risk of unauthorized access from credential stuffing or brute force attacks.

15. Supply chain attacks
    Supply chain attacks target a third-party vendor or supplier to access its client’s network. By compromising a trusted partner, threat actors can spread malware or gain access to secure data within the target organization. With NVIS AI’s centralized control and monitoring, supply chain risks are minimized as the solution provides full visibility into vendor access, ensuring that each connection complies with security standards.

16. Man-in-the-Middle (MITM) attacks
    MITM attacks occur when a cybercriminal intercepts communications between two parties, posing as a relay to manipulate data exchange or steal sensitive information. NVIS AI uses encrypted peer-to-peer communication, reducing MITM risks by securing data end-to-end and ensuring that only verified users can access sensitive exchanges.
