Network Security Course And Certification

What is Network Security: 

Network Security is the combined measures such as provisions and policies put in place to protect computer networks from unauthorised access, misuse or hijacks by hackers. 

Network Security is targeted towards protection of devices with network connections. 

Today, organization greatly rely on computer networks to share information throughout the organization in an efficient and productive manner. Organizational computer networks are now becomming large and ubiquitous. This has prompted the great need for Network Security. 

Network Security consists of the provisions and policies adopted by network administrator to monitor and prevent unauthorized access to a network, computer, application and network-accessible resources such as valuable data and information. 

What is a Network? 

A Network refers to two or more computer devices connected together. These connection can be categorized into two:

1. Wired Networks, and

2. Wireless Networks

Wired Networks involves connection of computers/devices through the use of cables known as 'Unshielded Twisted Pair (UDP) which connects devices such as routers and switches.

Wireless Networks are connected to an access points via radio transmissions. Wireless Network is currently the most used as it allows easy access and centralization of files, so much that it can be accessed from any location which makes it the most susceptible to attacks. 

Advantages of Network Security: 

The Benefits and Importance of Network Security include: 

1. Adequate protection on devices with network connections.

2. It facilitates protection of data and valuable information shared between computers on a network.

3. Ensures safety from external attacks to a network E.g Malwares, Viruses etc.

4. It helps in prevention of cyber attacks that may cause loss of data on the network.

5. It helps in detection/deletion of malicious files within preexisting network.

6. It helps to avoid the cost of rebuilding a network or computer. 

7. It helps our devices with long life-span. 

8. It helps to deter networks attacks.

9. It helps to detect and correct vulnerabilities of a network. 

10. It creates job opportunity.

Types of Network Security: 

1. Network Access Control (NAC): The NAC Security controls or determines the type of people who can gain access to your network such as Firewalls. 

2. Application Security: Application Security is designed to offer protection to your applications. It secures your network from application malfunction attacks. 

3. Antivirus And Antimalware Software: These type of security are used to protect files and data from network attacks or theft such as: spyware, phishing, trojans, malwares and viruses.

4. Email Security: For businesses that primarily operate using email communication, Email Security is very important because if hackers are able to get hold of companies information such as confidential or financial information, it can result to leakage of information, impersonation, scams, blackmail etc.

5. Wireless Security: Wireless connections is easily attacked because it is open, which is why wireless security measures is important and needs to be taken very seriously. 

Network Security Attacks: 

The various forms of Network Security Attacks include: 

1. Interruption: Interruption attacks are launched to disrupt service availability, such as of a DOS or Denial of Service Attack. The aim of this type of attack is to make sure that services of a network, application, software or website becomes unavailable. 

2. Interception: Interception attacks are launched to gain unauthorized access to a network. The aim of this type of network is to steal or damage valuable information on the network.

3. Modification: Modification attacks are launched to tamper or manipulate information or resources on a network. The aim of this type of attack is to cause miscommunication on the network. 

4. Fabrication: Fabrication attacks are commonly known as counterfeiting used to bypass authenticity checks or tests by impersonation or mimicking. The aim of this type of attack is to gain unauthorized access to a service or data with the use of fake or counterfeit information.
