How to setup and configure hostname in Red Hat Enterprise Linux 7
This tutorial is completely about hostname setup and hostname configuration in Red Hat Enterprise Linux 7. so if you are new to RHEL7 and you want to setup or configure hostname in your RHEL7 Machine then this tutorial is for you.Watch the below video carefully and you will very easily learn to configure hostname in RHEL7 Linux.
Why we set hostname in Linux machine?
Assigning a hostname to a PC or HOST is just like giving a name to an IP.
HOST means all the computers in a network.Each computer is a host in a network and the ip address assigned to that host machine or that computer is host address and the name given to that particular pc or computer or host is hostname.
IP assigned to the host pc or any pc in a network is known as host address and the name assigned to any pc or host in a network is known as hostname.
see it's not easy for anyone to remember ip address so we need a name for each ip in our local network to differentiate or to identify specific machine easily and to make our task easy.
Difference between HOST ADDRESS & HOSTNAME
IP assigned to the host pc or any pc in a network is known as host address and the name assigned to any pc or host in a network is known as hostname.
Why it necessary to set HOSTNAME in Linux?
see it's not easy for anyone to remember ip address so we need a name for each ip in our local network to differentiate or to identify specific machine easily and to make our task easy.Apache Web server configuration in RHEL 7

Network Security Related terminology you must know
Here in this article i am including the important terminology we need to know if we are working as a system engineer ,network engineer,system administrator whether Linux or Windows admin didn't matter.Here i will provide you the complete list of terms we need to know in networking or system admin field.Here in this tutorial i have discussed about various topics like pap,chap,asynchronous,,Tokens,throughput,RADIUS SERVER,TACACS,AAA,Data owner,subject,object,baseline,policies,procedures,standard,guideline,ARO,SLE etc
If we consider the topi regarding IT sector then Risk consists of these two important thing Threat and Vulnerability.where there is no Threat there is no risk.If there is Vulnerability in your system or Network and there is also threat of attack then risk is multiple effect of vulnerability.
This is an important terminology and every IT company have almost a separate department to handle ALE.
If you have a little knowledge off commerce field you can easily understand what asset value is.In short you understand it is a type of business valuation.
Total Cost of Ownership combining upfront costs and annual costs of maintenance
Policies are high-level management directives that don't go into specifics.
Procedures are step-by-step guides for accomplishing a task
says minimum amount required to do.
privileges are defined in every level whether it os operating system based or networking based.
operating system have several users created on privilege based. Administrator user have highest privilege than other and Guest user have least privileges than others.In Linux root have highest privilege.
In network deices like Routers and switches also have different privilege levels.
Need to know is more granular
Discretionary mean full control of objects they have access to
mandatory means system-enforced based on labels
role based, non-discretionary
Task-based = another non-discretionary method
Uses UDP 1812 and 1813. AAA system.
RADIUS request and response data is carried in
8-bit AVPs (Attritbute Value Pairs)
Tacacs is used for authentication and autheriation.
It is a centralized access control system that uses UDP port 49 and may use TCP
Objects have labels, and you have to have clearance to see them.
As we all know it is the most important point for any company institute or organiation and that is throughput. It is actually the biometric system response time.
Risk = Threat * Vulnerability
If we consider the topi regarding IT sector then Risk consists of these two important thing Threat and Vulnerability.where there is no Threat there is no risk.If there is Vulnerability in your system or Network and there is also threat of attack then risk is multiple effect of vulnerability.
ALE = Annualized Loss Expectancy
This is an important terminology and every IT company have almost a separate department to handle ALE.
AV = Asset Value
If you have a little knowledge off commerce field you can easily understand what asset value is.In short you understand it is a type of business valuation.
EF
EF means Exposure Factor - % of value lost
SLE
SLE stand for Single Loss Expectancy, the cost of a single loss.
ARO
ARO stands for Annual Rate of Occurrence (number of losses)
TCO
Total Cost of Ownership combining upfront costs and annual costs of maintenancePOLICIES:
Policies are high-level management directives that don't go into specifics.
PROCEDURES:
Procedures are step-by-step guides for accomplishing a task
Standard:
describes specific use of technologyGuideline:
recommendations (discretionary)Baseline:
uniform ways of implementing a safeguardData Owner
management employee responsible for ensuring protection of specific dataAAA
Authentication, Authorization, and Accountability
Least privilege
says minimum amount required to do.privileges are defined in every level whether it os operating system based or networking based.
operating system have several users created on privilege based. Administrator user have highest privilege than other and Guest user have least privileges than others.In Linux root have highest privilege.
In network deices like Routers and switches also have different privilege levels.
Need to know is more granular
Subject
active entity on a data systemObject
As we are here talking about computer and network system.In IT Sector or in computer field or networking department by saying OBJECT we mean passive data within the system.
Discretionary
Discretionary mean full control of objects they have access to
Mandatory
mandatory means system-enforced based on labels
RBAC
role based, non-discretionaryTask-based = another non-discretionary method
RADIUS
Uses UDP 1812 and 1813. AAA system.RADIUS request and response data is carried in
8-bit AVPs (Attritbute Value Pairs)
Diameter
RADIUS' successor with more accountability and a 32-bit AVP field.
TACACS
Tacacs is used for authentication and autheriation.It is a centralized access control system that uses UDP port 49 and may use TCP
PAP and CHAP
PAP stands for password authentication protocol and CHAP stands for challenged handshake authentication protocol.both used PPP connection.
PAP is plaintext so not so secure, while CHAP uses three way handshake. so chap is better than pap.You can READ:PAP Configuration Tutorial on cisco Router.
You can READ: CHAP Configuration on Cisco router.
Objects have labels, and you have to have clearance to see them.
Synchronous Dynamic Tokens
While talking about Synchronous Dynamic Tokens one must know that it't refresh every 60 seconds. Use time or counters to synchronize a code with the AS.Asynchronous Tokens
It is little different from Synchronous Dynamic Tokens and is not synchronized with central server. Challenge-response.
Throughput
As we all know it is the most important point for any company institute or organiation and that is throughput. It is actually the biometric system response time.make windows7/8/10 usb bootable using windows command promt

Default login name or username is easily hack-able so never user default username and password. Default login name and passwords are easily available on internet for approx all networking devices.
Here i will mention few steps to secure or protect your wi-fi device.
1.Always use a strong password for your wi-fi device.
When i say strong password it means it's lenghth must be 8 character.Strong password means it's combination of letter numeric and special character.Also mixture of small letter and capitla letter and it should not be matching with username or SSID name.Strong password means a password which is not guessable and which can't be remeber even seen in a glance.
2.Never use default login name or password.
Default login name or username is easily hack-able so never user default username and password. Default login name and passwords are easily available on internet for approx all networking devices.
3.Change your default SSID.
most of the people used to change the password only and not the SSID,but you should change the default SSID too because hacking software's available in market are designed for all default SSID and all default SSID names are already listed in hacking software's database.
4.Change Your default password even if it is a strong password.
Some people think that there default password is strong so no need to change it.Always remember default passwords are never safe.
5.Do discourage hacking attacks use a scary name.
Scary names keeps kids and hackers away from your network.
6.Keep checking connecting device list from your wi-fi router.
If you feel your network is used by someone else or someone else is also using your wi-fi device internet services then you must check it by login to your wi-fi router and check connected dvice list.You can use FING tool if you are using andoid mobile.
7.Enable MAC-Filtering based Security and allow each device with there mac address.
MAC-Filtering means allow or block any device from your wi-fi device using mac address of all devices whether it is computer laptop or mobile. Every device has it's mac address and they are fixed.
8.Keep your Wi-Fi software updated.
Always update your wi-fi router software
9.Reduce the range of your wi-fi signal.
Lesser the signal range minimum the chances of hacking.It will reduces the chances of hacking.
10.When you are not using Internet Just Turned it OFF.
When you are not using your wifi router you better turned it OFF.There is no point in keeping your wi-fi device on even when you are not using it.
11.Disable Guest network.
