Techniques used to identify unusual behavior in OT systems that may indicate potential threats.

Antivirus

Antivirus

Software designed to detect and remove malicious software in OT systems.

Application Whitelisting

Application Whitelisting

A security practice that allows only approved applications to run on OT systems to minimize risks.

Asset Inventory

Asset Inventory

A complete list of physical and digital assets in an OT environment is crucial for managing vulnerabilities.

Attack Surface

Attack Surface

The sum of all vulnerabilities and entry points an attacker can exploit in an OT system.

Audit Log

Audit Log

A record of events, actions, or changes within an OT system for monitoring and forensics.

Authentication

Authentication

Processes used to verify the identity of users, devices, or systems before granting access.

Authorization

Authorization

Granting or denying access to resources in an OT environment based on user roles or credentials.

Automated Response

Backdoor

Backdoor

An undocumented way of accessing a system, bypassing normal authentication, often exploited by attackers or left intentionally for maintenance purposes.

Backup and Recovery

Backup and Recovery

Regularly saving critical OT data and system configurations to protect against data loss and enable swift recovery after incidents.

Baseline Security

Baseline Security

The minimum security controls and measures established to protect OT systems and ensure compliance with standards.

Behavioral Analysis

Behavioral Analysis

A technique that monitors and analyzes the behavior of users, devices, or systems to detect anomalies or threats.

Binary Exploitation

Binary Exploitation

Techniques used by attackers to manipulate binaries (compiled programs) within OT environments to execute unauthorized commands.

Biometric Authentication

Biometric Authentication

Security measures that use unique physical traits, such as fingerprints or retinal scans, to authenticate users accessing OT systems.

Bitrate Monitoring

Bitrate Monitoring

Observing data transfer rates to detect unusual traffic that could indicate potential attacks or data exfiltration.

Blacklisting

Blacklisting

The process of explicitly blocking known malicious applications, IPs, or devices from interacting with OT networks or systems.

Botnet

Botnet

A network of compromised devices used collectively by attackers to perform coordinated cyberattacks, such as Distributed Denial of Service (DDoS) attacks against OT systems.
