CCNA security is one of the specialization certification for network security from Cisco.
To certify CCNA Security you should attend the exam code 210-260 IINS.And the Recommended Training is Implementing Cisco Network Security (IINS).
The Exam Duration is about 90 minutes, and there may have about (60-70 questions).ccna security exam cost is $250.
To attend and get CCNA Security Certification you should have any valid Cisco CCENT, CCNA Routing, and Switching, or any CCIE certification.After ccna security, you can prepare for higher certifications in security such as CCNP Security and CCIE Security.
To write Cisco certifications you need contact and Register Pearson VUE centers near to you.
Benefits of CCNA Security Certification
Become Security Specialist: if you are certified ccna routing and switching then at an enterprise you will know as the data engineer.Moreover, if you are a certified engineer of CCNA Security Then you will know as a security specialist(Security Engineer).
If you are a data engineer then you need to configure the protocols in router and switch configuration and establishing the network.But if you are security engineer then it is your responsibility to protect our network from the threat.Means our duty is to protect our network from outsiders to enter our network.Due to the mistakes from our side, others get hints and can access our network.
ex: somebody writes their pin number at top of ATM cards. It is easy to access others if they get this card.Likewise, In our network, we may put vulnerabilities by mistakes. It very helpful to others to make problems.
As a network specialist, it's our responsibility to protect our network from this kind of vulnerabilities (Hacking)in ccna security, we are mainly studying about the mistakes in our network and blocks its access to outsiders.
Network Protection
NFP(Network Foundation Protection) in this we will study network security.
In Network Foundation Protection, the full network infrastructure is divided into three.
1,Management Plane(Management function)
2,Control Plane(Control function)
3,Data Plane(Data function)
1, Management Plane
To configure the devices like router, switch, firewall we can connect it by putty or terra term or anything like that, and we access it by using protocols such as telnet or ssh. the functions which allow this kind of management protocols to configure router is known as management plane.
Example:ssh,putty,http,https,syslog.
We can configure Cisco routers by CMD line or we can use GUI (graphical user interface) configuration tool for configuring Cisco IOS routers such as security device manager (SDM) and Cisco Configuration Professional (CCP).Now using CCP commonly for GUI configuration.GUI using web page for configurations so it using protocols such as HTTP or https.
While we configure through command line we can see messages like configuring through the console.It is known as syslog.
Suppose if we are configuring anything in the router that will log it.We can create a centralized server for syslog management.Suppose if are configuring through Telnet then the person who using console get messages that some changes happened through Telnet.
We are using syslog messages and SNMP Protocol for the management functions.
SNMP: Simple Network Management, It’s a protocol using in network monitoring software.
Network Monitoring Softwares
1, PRTG Network Monitor.
It's an open sourced software you can download it from the Internet.Installing this on a machine you can monitor the devices such as router, switch, firewall in that network.This software sending SNMP to devices periodically and collects pieces of information to monitor it.
Suppose if the interface of the router is down then this software will inform it to the network administrator.If we are buying higher features of this software then it will inform network status changes by email and call.
2, SolarWinds:
It's an another monitoring tool using widely.It's expensive.Administrators say that it gives accurate pieces of information by email, message, and call.
