The ports most vulnerable to attack in TCP Protocol

Introduction

Surely you’ve heard of TCP, which ranks among the most important and widespread protocols.
In this post, we will talk about ” the ports most vulnerable to attack in TCP protocol “, according to a report by Alert Logic. We are going to define what is a Port and what is a TCP Protocol, then we will dig deep into ports that could easily attack. So, keep reading folks, it’s going to be interesting.

What is a Port?

It is a number or code that represents a vulnerability or gateway in computer operating systems; information flows through it when connected to the internet. Their purpose is to allow several services – or programs to work simultaneously within the network connection.

For each specific protocol port that uses this port. The number of that port is located within the data segment intended for transmission over the network and that number identifies the protocol as its specific code.
For Port numbering, it starts from 0 to 65536 ports divided as follows:

• Ports 0 to 1023: Well known for the products of companies such as Apple, MSN, and SQL Services.
• Ports 1024 to 49151: Registered protocol defined by software companies.
• The final range is Ports from 49152 to 65536, Especially for public use; i.e., can be used by everyone.

What is a TCP protocol?

Protocol standard includes a set of rules governing the process of data transfer. TCP is short for Transmission Control Protocol. A protocol that regulates the transmission of data according to a special mechanism with high reliability that does not allow data loss in the event of interruptions in the connection process.

The ports most vulnerable to attack in the TCP protocol

According to a report by the information security company Alert Logic, whose customers number 4000 companies. The most vulnerable ports in the TCP protocol are:

1-Port No. 22:

a protocol port (Secure Shell: SSH) that is used to access accounts and direct commands to systems remotely.

2. Port No. 80:

A port of the Hypertext Transfer Protocol (HTTP) used to browse websites on the internet.

3-Port No. 443:

A port of the Hypertext Transfer Protocol Secure: HTTPS, which is used for the Safe Browsing of websites.

4. Port No. 3389:

A Remote Desktop Protocol (RDP) port is used to remotely control another device over the network.

5. Port 20-21:

One is used for sending and the other for receiving, and then they are special in the File Transfer Protocol: FTP, which is used for transferring files over the network.

Alert Logic advises each organization to install a firewall for each host in its internal network. As well as monitor data flow and filter data flowing through ports and unused port lock with a series of periodic tests to verify that there are no security vulnerabilities.

Conclusion

To sum up, it is really important for us to know more about computer and internet security. Everything we do nowadays, it almost related to the internet. our transactions, our documents, our work, so we need to have the basics about what we dealing with. In this post ” the ports most vulnerable to attack in TCP protocol ” we took a step toward knowing these basics.
