It outlines best practices including changing defaults, stronger password policies, MFA, least-privilege administration, securing domain controllers, regular patching, auditing, isolation, and automation, and lists categories of third-party AD security tools. Closes with a brief mention of Teleport's own passwordless Windows access product. ## Full article daily.dev links to this article rather than hosting it.

The most common vulnerabilities include weak or reused passwords, poorly managed service accounts with old passwords and excessive permissions, overly broad user access beyond what is needed, and lack of visibility into login events. Attackers typically exploit these to steal credentials, move laterally, escalate privileges, and exfiltrate data over roughly a five-step attack chain. _daily.dev surfaces practical hardening guidance for teams securing identity infrastructure like Active Directory._ ### What are the best practices for hardening Active Directory against attacks? Key practices include changing default settings and group policies, enforcing strong unique passwords, enabling multi-factor authentication, applying least-privilege administration, securing domain controllers physically and against software attacks, keeping systems patched, auditing accounts and access regularly, isolating compromised workstations quickly, and automating permission updates when roles change. _Teams tightening identity security can track AD hardening techniques like these on daily.dev._ ### Why is Active Directory considered a high-risk target for cyberattacks? Active Directory is legacy technology not originally designed for modern threats, yet 97 percent of organizations consider it mission critical and cyberattacks succeed against it about 40 percent of the time. Breaches using stolen credentials are especially hard to detect, taking an average of 250 days to identify and 91 more days to contain, per IBM-Ponemon research. _daily.dev helps security-minded developers stay current on identity risks affecting infrastructure like Active Directory._ ## Similar posts on daily.dev - [Active Directory Under Siege: Why Critical Infrastructure Needs Stronger Security](https://daily.dev/posts/active-directory-under-siege-why-critical-infrastructure-needs-stronger-security-y32mujyio) · The Hacker News · 0 upvotes · 0 comments - [Domain Admin… and Beyond](https://daily.dev/posts/domain-admin-and-beyond-z1pvedvfd) · InfoSec Write-ups · 0 upvotes · 0 comments - [Inside AD CS Escalation: Unpacking Advanced Misuse Techniques and Tools](https://daily.dev/posts/inside-ad-cs-escalation-unpacking-advanced-misuse-techniques-and-tools-qejabt669) · Unit 42 · 1 upvotes · 0 comments - [Can you enforce strong Active Directory password rules without frustrating users?](https://daily.dev/posts/can-you-enforce-strong-active-directory-password-rules-without-frustrating-users--jdo5xruij) · BleepingComputer · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#authentication](https://daily.dev/tags/authentication), [#active-directory](https://daily.dev/tags/active-directory) [View this post on daily.dev](https://daily.dev/posts/active-directory-security-jqiuiygir) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Active Directory Security","url":"https://daily.dev/posts/active-directory-security-jqiuiygir","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/active-directory-security-jqiuiygir"},"datePublished":"2026-08-23T12:19:15.666Z","dateModified":"2026-08-23T12:33:39.130Z","description":"An introductory overview of Active Directory Domain Services (AD DS) security, covering why AD is a high-value attack target, common vulnerabilities such as...","image":"https://media.daily.dev/image/upload/s--foaA6JGU--/f_auto/v1722860399/public/Placeholder%2004","thumbnailUrl":"https://media.daily.dev/image/upload/s--foaA6JGU--/f_auto/v1722860399/public/Placeholder%2004","isAccessibleForFree":true,"articleSection":"Teleport","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Teleport","logo":"https://media.daily.dev/image/upload/s--Dw-Bbw6O--/c_limit,w_256/f_auto,q_auto/v1787487494/logos/teleport?_a=BAMAMicg0","url":"https://daily.dev/sources/teleport"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/active-directory-security-jqiuiygir","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,authentication,active-directory","timeRequired":"PT12M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Teleport","item":"https://daily.dev/sources/teleport"},{"@type":"ListItem","position":3,"name":"Active Directory Security"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/active-directory-security-jqiuiygir#faq","mainEntity":[{"@type":"Question","name":"What are the most common security vulnerabilities in Active Directory?","acceptedAnswer":{"@type":"Answer","text":"The most common vulnerabilities include weak or reused passwords, poorly managed service accounts with old passwords and excessive permissions, overly broad user access beyond what is needed, and lack of visibility into login events.
