- AD Security: An Urgent Priority for Enterprises
- The Rise of AD Cyber Threats and How to Counter Them
- Why You Should Assess Your AD Security Today
As cyberattacks targeting enterprises become more sophisticated, the importance of Active Directory (AD) security is gaining increasing attention.
A prime example of this trend is the selection of Semperis, a global IT security company, as one of CRN's 2025 Security 100 companies. With cyber threats targeting AD environments on the rise, businesses now require stronger security measures than ever before.
AD serves as a centralized infrastructure for managing users, groups, and systems within a company, but if compromised, the entire corporate network could be at risk.
According to the Korea Internet & Security Agency (KISA), AD-related attacks targeting domestic enterprises increased by 35% in 2023 compared to the previous year. In particular, ransomware attacks leveraging AD as a gateway for lateral movement have become more prevalent, leading to substantial financial and operational damage. So how can businesses enhance their AD security?
The Importance and Vulnerabilities of AD Security
AD is a critical system for authentication and access control within an organization, making it a golden key for cybercriminals seeking access to internal networks. In fact, some of the largest cyberattacks in recent years, including the 2019 CLOP ransomware attack and the 2021 Kaseya ransomware incident, have leveraged AD as a primary attack vector.
Hackers commonly compromise AD administrator accounts or exploit misconfigurations to escalate privileges, allowing them to gain full control over corporate networks. Once AD is compromised, attackers can dictate data encryption, theft, and even complete system shutdowns. Given these threats, reinforcing AD security is no longer optional—it is a necessity.
Expert Insights: Strategies to Strengthen AD Security
Taejeon Kim, Executive Director of NEOINE, emphasizes, "AD security is a core part of an enterprise's defense strategy. Beyond prevention, companies must also ensure they can quickly detect and recover from incidents." He advises businesses to implement the following measures to strengthen AD security:
1. Protect Administrator Accounts & Apply the Principle of Least Privilege
- Minimize the number of AD administrator accounts, granting access only when necessary.
- Enforce the principle of least privilege (PoLP) to limit user permissions.
- Regularly update administrator passwords and implement multi-factor authentication (MFA) to prevent unauthorized access.
2. Continuous Monitoring & Anomaly Detection
- Monitor suspicious login attempts or unauthorized privilege escalation in real time.
- Utilize security solutions to analyze AD event logs and detect unusual activity.
3. Apply Security Patches & Strengthen Security Policies
- Given the constant discovery of new AD vulnerabilities, organizations must apply security patches immediately.
- In November 2021, Microsoft released patches for AD privilege escalation vulnerabilities (CVE-2021-42278 and CVE-2021-42287). Failure to apply these patches could allow attackers to gain administrative control with minimal effort.
4. Establish AD Backup & Rapid Recovery Systems
- Regularly back up AD data and conduct recovery testing to ensure rapid restoration in case of an attack.
- Semperis has demonstrated that businesses equipped with efficient AD recovery solutions can reduce recovery time by over 90%.
Now Is the Time to Assess Your AD Security
Semperis’ selection in CRN's 2025 Security 100 highlights the growing priority of AD security for enterprises. The company’s comprehensive AD protection and recovery solutions help mitigate security risks, aligning with the security priorities emphasized by NEOINE and other cybersecurity firms.
NEOINE provides tailored consulting and security solutions to help domestic businesses reinforce AD security and mitigate cyber threats. Taejeon Kim underscores, "With cyber threats evolving at an unprecedented pace, failing to secure AD leaves a company’s core infrastructure completely exposed. Now is the time to assess and strengthen your AD security posture."
Is your company’s AD security truly secure? Now is the time to conduct an AD security assessment and implement proactive defense measures.
