| Abstract: | In view of the problem that Linux system has loopholes which are easy to overflow in its buffer, the procedures and methods,which are used by hijackers to attack these loopholes,are demonstrated. To stop the various attacks from hijackers, several corresponding typical countermeasures are proposed to clog loopholes and make up the shortage of the system itself, guranteeing the secure system operation. Practice shows that the proposed defending measures work effectively and improve the system security greatly. |
