Definition
Packet switching is the method of breaking data into smaller units, which are transmitted individually over a network, to make the transfer more secure and efficient.
Since the data travels as smaller data packets, it is easy to monitor and identify any security threats like malware. However, hackers can employ various tactics to cause data leaks, so you should always know how to protect your data.
Stopping Packet Switching Hacker Attacks
- Use strong and unique passwords: Always create passwords that are hard to guess using a combination of uppercase, lowercase, special characters, and numbers. This makes it hard for hackers to guess your password.
- Set up a two-step authentication: Hackers can use tools to guess passwords. So, you should implement 2FA since it requires a secondary verification method after inputting a password. You can set 2FA to send a verification code to your phone or email to alert you in case of unauthorized access.
- Use strong encryption: Implement robust encryption protocols such as AES and SSL/TLS to protect your data.
- Use firewalls and intrusion detection systems: This will help you control inbound and outbound traffic and monitor your network for potential attacks and suspicious activities.
- Avoid opening unknown attachments: Refrain from opening suspicious links or attachments. Phishing is the most common method hackers use to deliver malware on users’ devices to steal data and perform other malicious acts.
- Use reliable antivirus software: Install a reputable antivirus program to monitor malicious files and programs on your device. This will significantly lower the risk of being infected with viruses, spyware, ransomware, and other malicious files.
- Avoid public Wi-Fi: Hackers commonly target public Wi-Fi networks to inject malicious codes into devices that use them.
Types of Packet Switching
1. Connectionless Packet Switching
Connectionless packet switching or datagram switching involves individual routing of multiple packets. This means that each packet carries complete routing information. It also means the possibility of different transmission paths and out-of-order delivery depending on the fluctuating loads on the network’s nodes (routers, adapters, and switches).
2. Connection-oriented Packet Switching
Connection-oriented packet switching, virtual circuit switching, or circuit switching assembles and numbers data packets before they travel along a predefined route in sequence. Unlike connectionless switching, address information is unnecessary as packets maintain their order throughout transmission.
