Answer:
The certification developed by the SANS is GIAC certification .In this there are 3 certification GSEC,GISF and GCED .The description of these certification is given below .
Explanation:
The GIAC certification course is providing the knowledge of the security like cryptography ,networkig knowledge etc .
GSEC:The GSEC Certification is the certification of the security.It simply means this certification certified about the security risk in the computer system .
GISF: This certification gives the knowledge of the networking as well as the security in the computer system also it gives the knowledge of the cryptography.
GCED :This certification is also providing the knowledge of security as well as networking.
Difference between GIAC and InfoSec certifications is given below
- The SANS certification is giving the knowledge about the security risk as well as cryptography by the professional where as the InfoSec certifications providing the knowledge of the hacking by the professional .
- The SANS is including the certification of GIAC certification where as the InfoSec certifications is including the CISSP and SSCP certification .
Answer:
Only the last number of each IP address will be unique
Explanation:
Subnet Mask is used to identify the two parts of the IP address. One is the network part that should be same for one network, and other is host part that will vary with number of computer or devices that are connected to the network.
Subnet mask is 32 bit address that are divided in 4 equal parts of 8 bits. Each 8 bit converted to decimal by varying different bits to generate 256 different decimal number combinations. It means we can vary the address range between 0 to 255. So If any 8 bit portion is 255 that means, in this section we cannot add host address.
<u>For Example</u>
In given case,
Subnet Mask = 255.255.255.0
That means first three portions are fixed and has been allocated for network part.
The forth portion is 0 that means we can change this portion in IP address up to 255 different addresses.
So the IP address that is given can be vary as:
10.1.10. 186
10.1.10 This portion is network portion, this cannot be vary.
only the number 186 is the unique address that is particularly assigned to the devices and is vary between 0 to 255.
