Port Forwarding




Your friend wants to connect to your computer using RDC (remote desktop connection).
 Friend send request to your computer for Remote Desktop Connection to your public IP address with specific port number.

A port is logical connection is used by program and service to exchange information. Ports uniquely identify   this program and services that are running on a computer. In this case remote desktop connection uses 3389.

So, the request will make a way from computer to your router. Now you need to know where to forward the request for port 3389 because without any port forwarding configured your friend will not be able to connect because your router doesn’t know what to do with this request this is where port forwarding comes into play .So now we our going to tell our router to send or forward any request that is coming from 8339 and send to this computer. To do this we need to login into our router configuration page by in the routers internal IP address using a web browser.



Once you are in the configuration page .You need to go to the port forwarding section in order to port forwarding here in port forwarding page right all the detail asked by entering the port number which is 3389 and also enter the IP address of the computer that you want to access.

So, when your friend sends a request with port 3389 the router knows where send the request too and connecting is complete.
In port forwarding is used to give a path way for the router to forward request to the computer you want to forward.

Port Notes:
Port number ranges from 0-65535
Port 80:  HTTP-used for web page
Port 20,21: FTP (file transfer protocol)
Port 443: Https secure web pages

Secure Network(Week 4)

Network hardening is the process of securing a network by reducing its potential vulnerabilities through configuration changes and taking specific steps.   Implicit deny is a network security concept where anything not explicitly permitted or allowed should be denied. Analyzing logs is the practice of collecting logs from different networks and sometimes client devices on your network, then performing an automated analysis on them. Correlation analysis is the process of taking log data from different systems and matching events across the systems. Flood guards provide protection against Dos or denial of service attacks. EAP-TLS is an authentication type supported by EAP that uses TLS to provide mutual authentication of both the client and the authenticating server.   if you really want to lock down your network, you can implement 802.1x .

Troubleshooting and debugging

Troubleshooting is the process of identifying, analyzing, and solving problems.  Debugging is the process of identifying, analyzing, and removing bugs in a system. We sometimes use troubleshooting and debugging interchangeably.  But generally, we say troubleshooting when we're fixing problems in the system running the application, and debugging when we're fixing the bugs in the actual code of the application. Debuggers let us follow the code line by line, inspect changes in variable assignments, interrupt the program when a specific condition is met, and more. System calls are the calls that the programs running on our computer make to the running kernel.   A reproduction case is a way to verify if the problem is present or not. Where to check for log file in OS? On Linux , you'd read system logs like /var/log/syslog and user-specific logs like the .xsession-errors file located in the user's home directory. On MacOs , on top of the system logs, you'd go through...

Authentication Authorization Accounting(week 3)

C.R.L(Certificate revocation list) :This is a signed list published by the CA which defines certificates that have been explicitly revoked. Lightweight Directory Access Protocol(LDAP): LDAP is an open industry-standard protocol for accessing and maintaining directory services. Authentication is related to verifying the identity a user, authorization pertains to describing what the user account has access to or doesn't have access to. An access control list or ACL , is a way of defining permissions or authorizations for objects.  RADIUS or Remote Authentication Dial-In User Service , is a protocol that provides AAA services for users on a network.It's a very common protocol used to manage access to internal networks, WiFi networks, email services and VPN services. when a client wants to access a r...
