Basic network security knowledge is required for the CCNA. The CCNA Security training provides all of the network security topics that small and medium businesses need to know. There are three primary forms in networks: our networks’ susceptibilities, the risks we may face, and some attacks. If you are here to know the Network Security Factors in CCNA, You can join the CCNA Course in Chennai at FITA Academy. These factors are explained below.
- Vulnerability – These are the flaws in the network that we have. They could result from technology being used, device configuration, or poor or ineffective security practices. Security must be carefully designed in our networks, and these elements should be taken into account. A thorough security strategy is essential in assuring that the information in our server is not available owing to weak security on our systems.
- Threats – Anyone who has the capacity and willingness to control any vulnerability will be deemed a security threat. These persons or organizations can be motivated by a desire for money, authority, or excitement, among other reasons. Threats to data security are a huge concern for administrators, regardless of the goal, since they can access sharp or network-disabled data.
- Attacks – Threats employ these approaches to connect to the network. There are numerous ways to gain accessibility to our network. They may use methods such as dumpster diving to target network infrastructure or utilize social engineering to track users. Are you willing to learn CCNA Course?

Securing the network
The security problems in the network are many and cannot be protected in one chapter; the different techniques used by attackers to access webs have grave and far-reaching consequences; as such, we will focus on safeguarding routers and controls in this system. Some of the security techniques we will look at include:
- Physical security techniques
- Passwords
- SSH
- Port protection
Physical security
Physical attacks on network elements are a serious problem. As computer networks fail due to physical threats, a company’s products can be crippled. The four classes of physical threats are:
- Hardware threats– Network infrastructure, including servers, networks, and ports, is damaged.
- Environmental threats- are risks created by putting networking gadgets in insecure areas; hardware can be exposed to high moisture or temperature changes.
- Electrical faults- Because the technology in our networks is powered by electricity, any disruption in the power source to the connected devices poses a significant risk.
- Maintenance threats – We may need to perform service checks on our network elements from time to time, and the usage of unskilled professionals can put access points at risk.
Network security basics concepts– The CCNA exam covers a variety of networking concepts, including CCNA basics. It allows candidates to study CCNA fundamentals and prepare for the current network technology.
SSH (secure shell)
We discovered that we could administer our switches and routers remotely through virtual interface links or the router’s panel and accessory ports.
The local connection is the safest system, but you may not be permitted to connect to the network via console port in some instances. For example, While traveling, you might need to manage a router.
Although remote access makes it easier to manage hackers, it also increases risk. If we utilize simple text passwords, the attacker can grab the spaces containing the password. Learn CCNA Course In Bangalore with the help of experts in Networking and with career guidance.
