An LFM IDPS
Using an LFM which stands for log file monitor, the system
is able to review log files generated by servers, network devices, and even
other idpss. Its main purpose is to look for signatures and patterns which might
indicate that an intrusion is in the pipeline or has already happened.
This
intrusion detection is enhanced due to the fact that LFM is in a position to
look at several log files from different systems.
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
