References
CIS-13.4 Perform Traffic Filtering Between Network Segments mitigates T1187 Forced Authentication
Comments
Adversaries coerce systems into authenticating to attacker-controlled SMB or WebDAV resources in order to capture credential material. This control requires traffic filtering between network segments, which can block or tightly restrict SMB and WebDAV communications to untrusted or unauthorized destinations, directly preventing the outbound authentication path required by the technique.
References
CIS-12.8 Establish and Maintain Dedicated Computing Resources for All Administrative Work mitigates T1563.002 RDP Hijacking
Comments
Dedicated administrative workstations and segmented management networks reduce who can reach hosts carrying privileged RDP sessions and separate administrative activity from ordinary user networks. This does not prevent hijacking after the admin host itself is compromised, but it directly reduces network exposure of those sessions.
References
CIS-12.8 Establish and Maintain Dedicated Computing Resources for All Administrative Work mitigates T1563 Remote Service Session Hijacking
Comments
Adversaries hijack existing SSH, RDP, or other remote-management sessions. Keeping administrative sessions on dedicated, segmented resources reduces exposure of those sessions to compromised user endpoints and limits unnecessary network paths to privileged remote services.
References
CIS-12.8 Establish and Maintain Dedicated Computing Resources for All Administrative Work mitigates T1557 Adversary-in-the-Middle
Comments

References
CIS-12.2 Establish and Maintain a Secure Network Architecture mitigates T1200 Hardware Additions
Comments
Adversaries may introduce unauthorized devices onto the network. ATT&CK recommends network access controls such as 802.1X, device certificates, and restricting DHCP to registered devices; these are architectural admission-control mechanisms that directly prevent unauthorized hardware from communicating with trusted systems.
References
CIS-12.2 Establish and Maintain a Secure Network Architecture mitigates T1059.008 Network Device CLI
Comments
Adversaries use network-device CLIs to execute commands and modify device behavior. ATT&CK recommends AAA, least privilege, and command authorization such as TACACS+ to restrict which administrative commands users may execute. Because this control explicitly requires least privilege within the network architecture, this is a strong mapping when that architecture includes management-plane and command-access controls.
References
CIS-12.2 Establish and Maintain a Secure Network Architecture mitigates T1021.002 SMB/Windows Admin Shares
Comments

                                                      Comments
                                                      Application developers can use root-cause analysis to identify and remediate recurring authentication-validation weaknesses, such as missing replay protections, weak session controls, or flawed request validation. This reduces opportunities for adversaries to replay authentication messages, impersonate authorized parties, and conduct exploitation for credential access.

                                                        Application developers should exercise caution when selecting and integrating third-party libraries, using root-cause analysis of identified vulnerabilities to strengthen dependency-selection and management practices. This helps prevent supply-chain compromise through vulnerable or malicious software dependencies and development tools.

However, preventing unauthorized kernel module loading relies more heavily on platform integrity and driver enforcement controls (anti-malware product monitors and blocks malicious kernel modules, drivers, or extensions) than standard anti-malware alone.

Configuration controls remain necessary where the feature is still supported.

Most unsecured credential exposures require separate configuration, access-control, or secret-management controls.

Previously stored credentials may still require separate identification, removal, and rotation.

Remediation does not eliminate hash theft, NTLM use, or pass-the-hash through accounts that retain applicable privileges.

Many other execution-flow hijacking methods depend on writable paths, permissions, or configuration rather than a software vulnerability.

It does not prevent DLL hijacking in unpatched software or through writable application directories.

Operating-system and kernel vulnerabilities are addressed separately through operating-system patch management.

Other Office startup mechanisms that rely on macros, add-ins, templates, or configuration changes are not necessarily prevented by patching.

Most other execution-flow hijacking implementations require permissions, application control, or operating-system configuration protections.

Extension allowlisting and trusted-source restrictions remain necessary to prevent malicious extensions.

It does not prevent cookie theft by malware or an adversary that already has sufficient access to browser storage or memory.

Other protections are still required against adversaries that already possess authorized firmware-update capability.

Other pre-OS persistence methods may require boot-integrity, signing, and hardware-root-of-trust controls.

This creates a direct preventive relationship when blocking or quarantine is enforced.

Disabling these operating system features directly interrupts the automatic execution mechanism used to propagate malware through removable media, forcing an attacker to rely on manual execution or another execution vector.

Certificate and SSH host-key validation remain essential to the effectiveness of the mitigation.

Common malicious usage includes automating execution of behaviors with VBScript or embedding VBA content into spearphishing Attachment payloads. If .VB objects are blocked at the email boundary then it can mitigate the spearphishing delivery of this technique.

Attackers frequently embed malicious scripts (e.g., .js, .vbs) inside legitimate document formats (e.g., PDFs, Word docs). By blocking macro-enabled or script-based file types, gateways prevent these malicious combinations from ever reaching the user's inbox

It does this by requiring updated network-based URL filtering across all enterprise assets, using methods such as category-based filtering, reputation-based filtering, and block lists. In practice, this means enforcing controls that restrict access to unsafe websites, malicious downloads, risky scripts, and unauthorized browser extensions, reducing the risk of phishing, exploitation, and malware delivery.

In practice, this means enforcing controls that restrict access to unsafe websites, malicious downloads, risky scripts, and unauthorized browser extensions, reducing the risk of phishing, exploitation, and malware delivery. If 9.3 implementation blocks outbound traffic from machines to unapproved external destinations. Restricting access to known, trusted IP addresses and protocols can prevent attackers from downloading malicious tools or payloads onto compromised servers after gaining initial access.

Using common services, such as those offered by Google or Twitter, makes it easier for adversaries to hide in expected noise. 9.3 helps prevent link-based and web-based initial access by stopping users from reaching malicious or unapproved content. If 9.3 implementation includes outbound web-services used broadly enough to block unauthorized services and restrict access to unsafe websites, then this technique is defensible.

If 9.3 implementation blocks unapproved social media, code repositories, paste sites, and similar web services across enterprise HTTP/S traffic, this becomes defensible. Adversaries may post content, known as a dead drop resolver, on Web services with embedded (and often obfuscated/encoded) domains or IP addresses. Once infected, victims will reach out to and be redirected by these resolvers.

It does this by requiring updated network-based URL filtering across all enterprise assets, using methods such as category-based filtering, reputation-based filtering, and block lists. In practice, this means enforcing controls that restrict access to unsafe websites, malicious downloads, risky scripts, and unauthorized browser extensions, reducing the risk of phishing, exploitation, and malware delivery. If 9.3 implementation includes certain risky or suspicious web-services used broadly enough to block unauthorized services, then this technique is applicable.
