What student say about Octa Networks

Best place to learn and practice the networking technology. Thank you Mr. Sancchit Puri for your detailed explanation and guidance.
Ahamed Rizam
Best place for networking courses with qualified teachers...
Farhan Qureshi
octa networks are experts in networking and every one can learn networking easily by their wonderful teaching
Jawahar Annadhurai
Very good place to learn, convinent ours that fits your work Schedule, Sanchit is one of awesome Instructure I am taking class with, we are not just taking online class just to sit and watch, we actually interact and share Ideas in the class
Omar Monads
One of my friends recommended about this to me and unfortunately I ignored him for few months. Later I agreed him joined their classes. Since then I was blaming myself for not joining before. They are excellent in technology classes. They have students worldwide . If you want to get your #CCIE_Digit this is the right place for sure. When it comes to RnS classes, Sancchit Puri, You are the best!!!
Ravindu Yasanga

"Hi Connections, I wanted to share my experience of clearing CCIE Security. To take the training i enrolled to Octa Networks, Mostly i followed the Cisco blue print in order to do my CCIE written exam and lab exam preparation, I really appreciate my Trainer Naiman Shaikh, who really helped me in order to clear my concepts and for guiding me through out my exam. The way he explains the concepts is really very good. It was a long journey and it ended with a great result. In order to clear any exam we need the proper guideline, And that i got from Octa Networks. Looking forward to make my skills even more stronger and looking forward for more and more exposure in security in live environment. Thank you so much Arshad Dhunna Joaquim Fernandes Naiman Shaikh Dhansingh Rawat Octa Networks for being with me and for helping me and for guiding me well."

    string(2075) "In this article we will discuss Server Message Block, will make brief discussion on Server Message Block, In last article we discuss about File Transfer Protocol.The Server Message Block (SMB) is a client/server file sharing protocol that describes the structure of shared network resources, such as directories, files, printers, and serial ports. It is a request-response protocol. All SMB messages share a common format. This format uses a fixed-sized header, followed by a variable-sized parameter and data component.
    SMB messages can:
    • Start, authenticate, and terminate sessions
    • Control file and printer access
    • Allow an application to send or receive messages to or from another device
    SMB file-sharing and print services have become the mainstay of Microsoft networking. With the introduction of the Windows 2000 software series, Microsoft changed the underlying structure for using SMB. In previous versions of Microsoft products, the SMB services used a non-TCP/IP protocol to implement name resolution. Beginning with Windows2000, all subsequent Microsoft products use DNS naming, which allows TCP/IP protocols to directly support SMB resource sharing.Unlike the file sharing supported by FTP, clients establish a long-term connection to servers. After the connection is established, the user of the client can access the resources on the server as if the resource is local to the client host.The LINUX and UNIX operating systems also provide a method of sharing resources with Microsoft networks using a version of SMB called SAMBA. The Apple Macintosh operating systems also support resource sharing using the SMB protocol."

    What Is ARP Spoofing?

    ARP spoofing is a type of attack in which a malicious actor sends falsified ARP (Address Resolution Protocol) messages over a local area network. This results in the linking of an attacker’s MAC address with the IP address of a legitimate computer or server on the network. Once the attacker’s MAC address is connected to an authentic IP address, the attacker will begin receiving any data that is intended for that IP address. ARP spoofing can enable malicious parties to intercept, modify or even stop data in-transit. ARP spoofing attacks can only occur on local area networks that utilize the Address Resolution Protocol.

    ARP Spoofing Attacks

    The effects of ARP spoofing attacks can have serious implications for enterprises. In their most basic application, ARP spoofing attacks are used to steal sensitive information. Beyond this, ARP spoofing attacks are often used to facilitate other attacks such as:
    • Denial-of-service attacks: DoS attacks often leverage ARP spoofing to link multiple IP addresses with a single target’s MAC address. As a result, traffic that is intended for many different IP addresses will be redirected to the target’s MAC address, overloading the target with traffic.
    • Session hijacking: Session hijacking attacks can use ARP spoofing to steal session IDs, granting attackers access to private systems and data.
    • Man-in-the-middle attacks: MITM attacks can rely on ARP spoofing to intercept and modify traffic between victims.
    ARP Spoofing TutorialARP spoofing attacks typically follow a similar progression. The steps to an ARP spoofing attack usually include:
    1. The attacker opens an ARP spoofing tool and sets the tool’s IP address to match the IP subnet of a target. Examples of popular ARP spoofing software include Arpspoof, Cain & Abel, Arpoison and Ettercap.
    2. The attacker uses the ARP spoofing tool to scan for the IP and MAC addresses of hosts in the target’s subnet.
    3. The attacker chooses its target and begins sending ARP packets across the LAN that contain the attacker’s MAC address and the target’s IP address.
    4. As other hosts on the LAN cache the spoofed ARP packets, data that those hosts send to the victim will go to the attacker instead. From here, the attacker can steal data or launch a more sophisticated follow-up attack.
     

    ARP Spoofing Detection, Prevention and Protection

    The following methods are recommended measures for detecting, preventing and protecting against ARP spoofing attacks:
    • Packet filtering: Packet filters inspect packets as they are transmitted across a network. Packet filters are useful in ARP spoofing prevention because they are capable of filtering out and blocking packets with conflicting source address information (packets from outside the network that show source addresses from inside the network and vice-versa).
    • Avoid trust relationships: Organizations should develop protocols that rely on trust relationships as little as possible. Trust relationships rely only on IP addresses for authentication, making it significantly easier for attackers to run ARP spoofing attacks when they are in place.
    • Use ARP spoofing detection software: There are many programs available that help organizations detect ARP spoofing attacks. These programs work by inspecting and certifying data before it is transmitted and blocking data that appears to be spoofed.
    • Use cryptographic network protocols: Transport Layer Security (TLS), Secure Shell (SSH), HTTP Secure (HTTPS) and other secure communications protocols bolster ARP spoofing attack prevention by encrypting data prior to transmission and authenticating data when it is received.
