Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls. Authentication processes generally require a valid identity (e.g., username) along with one or more authentication factors (e.g., password, pin, physical smart card, token generator, etc.). Alternate authentication material is legitimately generated by systems after a user or application successfully authenticates by providing a valid identity and the required authentication factor(s). Alternate authentication material may also be generated during the identity creation process.(Citation: NIST Authentication)(Citation: NIST MFA) Caching alternate authentication material allows the system to verify an identity has successfully authenticated without asking the user to reenter authentication factor(s). Because the alternate authentication must be maintained by the system—either in memory or on disk—it may be at risk of being stolen through Credential Access techniques. By stealing alternate authentication material, adversaries are able to bypass system access controls and authenticate to systems without knowing the plaintext password or any additional authentication factors.

Mitigation	Description
Mitigations
Audit	Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses.
Password Policies	Set and enforce secure password policies for accounts.
Account Use Policies	Configure features related to account use like login attempt lockouts, specific login times, etc.
Privileged Account Management	Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.
Active Directory Configuration	Implement robust Active Directory configurations using group policies to control access and reduce the attack surface. Specific examples include: * Account Configuration: Use provisioned domain accounts rather than local accounts to leverage centralized control and auditing capabilities. * Interactive Logon Restrictions: Enforce group policies that prohibit interactive logons for accounts that should not directly access systems. * Remote Desktop Settings: Limit Remote Desktop logons to authorized accounts to prevent misuse by adversaries. * Dedicated Administrative Accounts: Create specialized domain-wide accounts that are restricted from interactive logons but can perform specific tasks like installations or repository access. * Authentication Silos: Configure Authentication Silos in Active Directory to create access zones with restrictions based on membership in the Protected Users global security group. This setup enhances security by applying additional protections to high-risk accounts, limiting their exposure to potential attacks.
Application Developer Guidance	This mitigation describes any guidance or training given to developers of applications to avoid introducing security weaknesses that an adversary may be able to take advantage of.
User Account Management	Manage the creation, modification, use, and permissions associated to user accounts.

Detection

Configure robust, consistent account activity audit policies across the enterprise and with externally accessible services.(Citation: TechNet Audit Policy) Look for suspicious account behavior across systems that share accounts, either user, admin, or service accounts. Examples: one account logged into multiple systems simultaneously; multiple accounts logged into the same machine simultaneously; accounts logged in at odd times or outside of business hours. Activity may be from interactive login sessions or process ownership from accounts being used to execute binaries on a remote system as a particular account. Correlate other security systems with login information (e.g., a user has an active login session but has not entered the building or does not have VPN access).
