The --tables switch enumerates table names, and -D dojo_control scopes that enumeration to the dojo_control database. The enumeration result contains three tables.

A buffer overflow occurs when input exceeds a program’s allocated memory buffer, potentially overwriting adjacent memory or control data. An attacker can use the overflow to execute a supplied command or bypass normal authentication, resulting in administrative access without valid credentials.

A business network and a control-server network require separate security boundaries, so they should use separate Active Directory domains with no trust relationship. Domains in the same Active Directory forest are automatically connected by two-way transitive trusts; that would allow cross-domain authentication rather than preserving isolation.

Static cryptographic keys are commonly stored in persistent device memory so the device can authenticate or encrypt communications after reboot. A data-at-rest acquisition can therefore expose those keys.

Fuzzing supplies invalid, unexpected, malformed, or random data as inputs to identify errors, crashes, and potential security vulnerabilities.

Responsive physical security controls define the actions taken after a security incident or breach has occurred, such as incident-response and emergency procedures.

Round-robin scheduling allocates CPU time slices among multiple runnable processes, a pattern typical of general-purpose operating systems on an operator workstation. Dedicated embedded devices, field sensors, and data diodes usually perform narrowly defined functions and commonly use deterministic or single-purpose execution models.

A disaster recovery plan documents recovery activities and should be aligned with incident-handling procedures so that containment, recovery, and restoration activities can be coordinated. Access-control policies and backup policies address specific controls, while vulnerability reports record assessment findings rather than define incident-handling operations.

Secure Simple Pairing is a Bluetooth BR/EDR pairing and security mechanism, supporting methods such as numeric comparison, passkey entry, and out-of-band pairing.

Boundary filtering should perform anti-spoofing: packets arriving from outside the protected network must be dropped when their source address claims to be an address assigned within that protected network. This prevents forged-source traffic from bypassing trust assumptions. CISA guidance recommends inbound filtering that blocks packets whose source addresses are assigned to internal networks.

A request-forgery link can cause an HMI action only when the victim’s browser has an active authenticated session with the HMI interface, so its existing session credentials are included with the request.

Control of the operating system can provide access to the applications running on that system, including the ICS application and the information it stores or processes.

A CERT (Computer Emergency Response Team) coordinates incident response, risk reduction, and security-threat information with affected organizations and, when appropriate, law-enforcement agencies.

Weaker password requirements reduce authentication security and increase the likelihood of unauthorized access during recovery operations.

Secedit.exe provides command-line security-configuration functions that can be scripted to apply security policy settings on workstations. It is therefore suitable for scripted deployment outside Active Directory management.

Common Weakness Enumeration (CWE) is a community-developed taxonomy of common software and hardware weaknesses that can lead to vulnerabilities. It organizes and describes weakness types; CVSS instead measures the severity of individual vulnerabilities.

The Recovery phase returns affected systems to secure normal operation. Applying patches and configuring systems to established secure configuration standards removes known weaknesses and helps prevent recurrence before systems are fully restored to service.

A WirelessHART device uses its join key to encrypt the join request, proving authorization to join the network. Once authenticated, it can receive the shared network key for subsequent network communications.

Virtualization supports isolated test environments where new patches can be evaluated for compatibility and operational impact before deployment to production ICS systems.

Modbus function code 5 performs a Write Single Coil operation, which sets the state of an individual coil.

General-purpose PLCs execute user-programmed control logic and can be repurposed for varied automation functions. Smart field devices are built for specific field functions and use embedded control logic rather than freely changeable general-purpose application logic.

Audit records for both successful and failed login attempts provide accountability and help detect, investigate, and respond to unauthorized database access. Security logging guidance identifies failed logons and access events as relevant event types for auditing, while administrative access should follow least privilege and remote management should use protected protocols.

MECM includes hardware and software inventory capabilities as part of its broader endpoint-management feature set, whereas WSUS primarily manages Microsoft software updates.

Creating a forensic image preserves evidence from the compromised workstation before eradication or recovery changes its state. Evidence preservation is part of containment; re-imaging, patching, and validating remediation occur later in eradication or recovery activities.
