Algorithm 3: The threat degree of elementary intrusion algorithm

Input: The Stack of Integer value. Output: threat. 1. The number of different priorities attack from different source at the same time is stored in the object value; 2. h = value.get(4); 3. m = value.get(3); 4. l = value.get(2); 5. lst = value.get(1); 6. k = value.get(0); 7. for (int i = 0; i < 5; i++){ 8. sum1 = h*Math.pow(10, 5*1) + m*Math.pow(10, 4*0.8) + l*Math.pow(10, 3*0.6) + lst*Math.pow(10, 2*0.4) + k*Math.pow(10, 1*0.2); 9. int sum = h + m + l + lst +k; 10. if(sum==0){ 11. return 0;}} 12. double weight = sum1/(sum*100); 13. double threat = Math.pow(10, weight); 14. Return threat.
