In this article, we will explain who are intruders in network security.
Network security is a complex topic. There are many types of intrusions, from viruses to worms to Trojans.
Let’s take a closer look.
Who Are Intruders in Network Security?
Intruders in network security are those who try to gain unauthorized access to the network or computer.
The most common methods of intrusion are Trojan horses, worms, viruses, and phishing. Intrusions are possible on all levels of the network: on a local computer (a single machine), server, LAN, WAN, or the Internet.
Intruders in network security can be:
Individuals
Those who want to get access to your data for their own needs. It may be that they steal information or files from your computer.
Hackers
These people break into computers or networks for fun or self-promotion. Hackers often use their hacking skills to steal money.
Organized criminal networks.
These people break into computers or networks to steal money, and data or perform other illegal activities.
State intelligence services.
They may use their skills in computer and network security for espionage, surveillance, and other illegal activities.
Terrorists
They may use their skills to create a network of viruses and worms and infect other computers to disrupt the functioning of critical infrastructure.
Tools To Prevent These Intruders in Network Security
There are several methods to prevent intruders in network security.
1. Protect the hardware of your computer and network equipment.
You should protect the hardware with passwords and encryption. Hackers can not gain access to your computer if they do not know its password.
Encryption protects your data from unauthorized access even if the hard drive is stolen. Also, you can install firewalls and antivirus software on the computer and network equipment.
These tools will protect your computer from intruders in network security.
2. Using a virtual private network (VPN).
A VPN allows you to connect to a private network from any location, as long as you have an Internet connection. In this case, the data will be encrypted and not available to third parties.
3. Using the principle of least privilege.
This means that you should allow users to use the minimum amount of privileges necessary to perform their work.
It is important to ensure that users do not have access to all computers in a network. Otherwise, they can access any information stored on these computers.
4. Regulating user passwords.
It is important to ensure that you did not disclose passwords to outsiders and that you change it regularly. It is also advisable to set up specific rules for password length and complexity.
5. Encrypting data traffic over the Internet in transit.
This means that data sent over the Internet is encrypted while in transit to the destination.
If data is not encrypted, third parties can intercept it. Encryption provides protection even if the data is intercepted.
Intruders in network security are a real threat to computer and network security. However, you should not be afraid of them as long as you use appropriate measures to protect your computer and network.
