RESTON, VA (November 30, 2006) Learning Tree International (NASDAQ NM: LTRE) announced today it will be extending its IT Security curriculum with a new course entitled Ethical Hacking and Countermeasures: Hands-On. The 4-day course will consist of an expert instructor leading attendees in extensive hands-on exercises designed to model hacking methods and heighten awareness for the purpose of improving organizational security measures.

Participants will also be taught how to:

• Deploy ethical hacking to expose weaknesses and select countermeasures
• Gather intelligence using social engineering, published data and scanning tools
• Improve their security by probing and compromising their network using hacking tools
• Prevent intrusions by protecting against privilege escalation
• Defend against evasions of antivirus, firewalls and IDS

“Professionals attending this course will be introduced to the same mindset and methods hackers employ as they seek to discover network weaknesses, thus presenting them with the opportunity to better mitigate and reduce those risks for their own organizations,” said Jennifer Urick, Vice President of Product Development for Learning Tree International.

Ethical Hacking and Countermeasures: Hands-On is valuable for security consultants, auditors, firewall/IDS personnel and those responsible for securing enterprise systems from unwanted intrusion.

Ethical Hacking and Countermeasures: Hands-On augments existing Learning Tree security-related courses, including Introduction to System and Network Security, Deploying Internet and Intranet Firewalls: Hands-On, Hands-On Introduction to TCP/IP, UNIX and Linux Security: Hands-On, Securing Windows Server 2003: Hands-On, Computer Forensics and Incident Response: Hands-On, Disaster Recovery Planning: Ensuring Business Continuity and Vulnerability Assessment: Protecting Your Organization.
