Secure Your Active Directory to Disrupt Attack Paths
Tenable.ad Helps you See, Predict and Act to Proactively Address Active Directory Vulnerabilities
When successfully breached, your Active Directory can be a gateway for attackers looking to make lateral movements through your network, often undetected. Unfortunately, Active Directory security is an often-overlooked, but important part of securing your enterprise. With Tenable.ad, you can quickly find and fix Active Directory vulnerabilities, disrupt attack paths, prevent lateral movement, and stop privilege escalation before a breach happens.
Securing Active Directory: How to Proactively Detect Attacks
Attackers have a sophisticated approach to Active Directory attacks, an attack pathway often overlooked by organizations, even those with a relatively mature cybersecurity program. And even for organizations that are aware Active Directory can come under attack their traditional approach to security just doesn’t work well for Active Directory.
Over the years, Microsoft has offered up some security solutions for on-premises Active Directory security, but few, if any, of them have had the sticking power for organizations to commit to them. Instead, they’re often short-lived or replaced with other solutions. While other security solutions have edged into the market over the past two decades, for example, group policy management, they just don’t offer true, comprehensive security for your Active Directory environment. That’s because new attacks are complex and often hidden and detection isn’t always easy.
Most Active Directory solutions were created a decade or so ago and they just haven’t kept up with the changing Active Directory environment which now encompasses more assets and more diverse asset types. While some solutions like AD monitoring or SIEM may alert if they uncover an issue, few can proactively detect a wide array of attacks, preventing your organization from taking action to fix misconfigurations or other issues.
Tenable.ad, however, doesn’t need an attack log before it can alert you to issues. Instead, it uses your raw AD replication stream to find problems before a successful breach.
In this white paper, learn more about other common Active Directory security challenges and find out how Tenable.ad can help you conquer them, including:
- How attacks use misconfigurations for privileged access
- How you can discover misconfigurations in your Active Directory
- How to employ proactive solutions that work across all of your Active Directory installations
A Global Threat to Enterprises: The Impact of Active Directory Attacks

In this white paper, take a closer look at some of today’s most common Active Directory risks and the potentially catastrophic impacts they can have on organizations, including a closer look at 15 significant corporate breaches and best practices to protect your Active Directory from similar attacks.
You can also explore five high-level risks that your organization should make a priority to address, including the impact of Active Directory attacks on business continuity, brand damage and customer trust, and competitive loss and IP threats. This white paper also offers practical tips to help your organization implement effective Active Directory security, including the adoption of automation tools and real-time event monitoring.
A King's Ransom: How to Stop Ransomware Spreading via Active Directory
Security breaches are expensive and cost businesses as much as $170 bullion every year. In 2019 alone, hacking cost the U.S. about $3.5 billion. Attackers know Active Directory holds the keys to your kingdom, so they’re continuously looking for ways to infiltrate your systems through AD and laterally move unnoticed.
One of attackers’ favorite methods is ransomware deployment through Active Directory, where organizations, on average, pay about $84,000 in ransom following a successful breach. But your Active Directory doesn’t have to be vulnerable to these attacks. In this white paper, you can take a deeper dive into how you can prevent ransomware spread through your Active Directory with six quick tips to protect access to your privileged Active Directory accounts.

LDAP searches returning only 1000 result
When performing Active Directory/LDAP searches for assets or users in Tenable.sc, you may encounter situations where there is only a maximum of 1000 results returned regardless of the actual number of users/assets that match the query in LDAP/Active Directory.Read More
Login Type Shown as (authentication: password) When Failing to Login with an LDAP User Account
If you set up an LDAP user account and then change the case of the username, that will break the Tenable.sc connection to that Active Directory user account. When that user attempts to login, it will fail.Read More

Introducing Tenable.ad: Secure Active Directory and Disrupt Attack Paths
Attackers are looking for ways to get into your Active Directory environment so they can move laterally, escalate privileges, and take over your domain. They’re counting on your team missing Active Directory vulnerabilities and misconfigurations so they can take advantage of them. But you don’t have to leave your domains unprotected any longer.
Tenable.ad enables continuous detection to help you proactively prevent Active Directory attacks, and you can deploy it quickly without agents or privileges. Check out this webinar to learn more about how Tenable.ad can help you secure your Active Directory including:
- How you can discover and prioritize your Active Directory risks
- How you can uncover common Active Directory attacks such as brute force, password spraying, DCShadow, DCSync, and others
- How you can improve your incident response by adding Active Directory data into your SIEM, SOAR, or SOC
If you want to prevent attackers from being able to move laterally within your network and escalate privileges, then you should include Active Directory security into your risk-based approach to cybersecurity. If an attacker successfully gets access into your Active Directory, they’re likely to seek out high-level privileges so they can get access to more information and move deeper into your systems, creating backdoor access that is often unnoticed. Tenable.ad, however, shines a light on these hidden pathways, giving your organization opportunities to stop attacks before they happen including insight into new admin account creation, permission changes, new trust relationships, and more.
Active Directory has a number of security issues attackers can exploit, including negating password requirements with a simple command, something commonly missed during routine security reviews and audits. This blog explores three simple ways you can secure accounts including creating a saved query in Active Directory with a custom LDAP, using the PowerShell module, continuously monitoring all users to ensure none are set up to not require a password.
Did you know that attackers can get access to your Active Directory by using the SDProp process and then gain privileges through your adminSDHolder object? Attackers know that if they have a rogue user or group to adminSDHolder ACL, when your SDProp process runs, they can get access to every privileged user and group automatically, sometimes even adding them back 60 minutes after being discovered and having the user or group removed. Who has time for that much manual monitoring though? The good news is Tenable.ad can handle it for you, constantly evaluating your attack pathways and alerting you when there’s a new one.
Although it’s been around for more than 20 years, Active Directory has been adaptable to meeting changing business needs, which is visible in its increased adoption and usage. But unfortunately, many organizations using Active Directory don’t know how to properly secure it, and many don’t know what they need when they’re looking for an Active Directory security solution. This blog takes a deeper dive into the top 10 questions every CISO should ask before finalizing your short-list for a new Active Directory security solution. With careful planning, you can ensure your organization selects a solution that is both resilient and can scale with you over time.
Weak and misconfigured settings are a gateway for attackers wanting to get access into your Active Directory so they can make lateral movements and escalate privileges, often without you knowing they’re there. You can prevent and detect Active Directory attacks simply, with automation, with Tenable.ad.
