בהמשך להצלחה בחג החנוכה, ועקב בקשות למופע נוסף לאלו שלא הספיקו להשיג אישורים תקציביים מהחברות שלהם, רון מוניץ ילמד בסוף חודש ינואר קורס פומבי בנושא פיתוח קרנל, ואינטרנלס.
הקורס הינו קורס רשמי של ה Linux Foundation.
הקורס מתאים למפתחי קרנל עתידיים\נוכחיים שרוצים לעשות סדר בדברים, ולמומחי אבטחת מידע.
הקורס יערך במרכז הארץ או בחיפה (כתלות בנרשמים המהירים), בשפה העברית, בתאריכים הבאים:
22 בינואר, 23 בינואר, 1 בפברואר, 2 בפברואר. הקורס מפוצל לשני שבועות, בכדי להקל על חברות - (וגם כי רון עסוק בין לבין :-) )

להצעת מחיר והרשמה ,יש לשלוח מייל ל training@thepscg.com

שימו לב שהקורס הוא תנאי חובה למגיעים למופעי קורסי אבטחת ודיבאגינג הקרנל שיינתנו בחודש פברואר ומרץ, וחוקרים בלי נסיון משמעותי בקרנל לא יוכלו להרשם לקורסים הבאים מבלי לקחת את הקורס הנוכחי.

Linux Kernel Internals and Development (LFD420)

Length: 4 Days

Type: Hands-On

Target Audience: Prospective Linux Kernel developers, security researchers, board designers, system administrators, Real-Time/embedded engineers making the transition to Linux, device drivers developers.


  • Essential:

    • The attendees should proficient with C and assembly language

  • Recommended:

    • Working knowledge of Linux command line tools

    • Previous Device Driver or Embedded Linux experience


Linux Kernel Internals and Development course provides experienced programmers with a solid understanding of the Linux kernel. Upon mastering this material, you will have a basic understanding of the Linux architecture, kernel algorithms, scheduling, hardware and memory management, modularization techniques and debugging, as well as how the kernel developer community operates and how to efficiently work with it. The course includes extensive hands-on exercises and demonstrations designed to give you the necessary tools to develop and debug Linux kernel code.

The course is based on both the most upstream recent Linux kernel version, and maintains compatibility with the kernel versions used by at least the last two releases of the major Linux distributions.

Note: The course can be customized to a 5 day version which includes more debugging material.

posted Oct 2, 2015, 2:55 PM by Ron Munitz

The upcoming Android Security course planned on October 18th is sold out, and unfortunately I cannot accept any more registrations.
Given the number of inquiries, I may open another course towards the end of the month, and at the moment it seems the chances are high the course will indeed open. 
Otherwise, the next Public course is scheduled for Q1 2016. 

Should you be interested in a public course this month, or in corporate training - email training@thepscg.com .

A number of Public "Android Security" courses will be given during October and November of 2015 in the EMEA
