Key Takeaways

Imagine this. You're managing a growing business with sensitive customer data and company secrets and suddenly you hear about a cyber attack that threatens the security of critical systems and you realize that your network needs protection and that's where the powerful tools like forgate firewall comes into the play. In today's world, cyber threats are becoming more sophisticated and and every business large or small is a potential target. Whether you are a startup or a government organization or a global corporation, ensuring your network is secure is very essential. 48 firewalls offer top tier protection blocking malicious traffic and safeguarding your networks from hackers, viruses, and data breaches. So guys, in today's tutorial, we are going to explore what exactly is forgate firewalls. So guys, here's the agenda of our today's session. First, we are going to start with an overview of Forigate. Then we are going to learn about interfaces and routing. Then we are going to explore the firewall policies. Moving ahead, we are going to discuss about a real world scenario about authenticating network users and integrating LDAP for user authentication. Then we are going to discuss bit about inspecting SSL traffic and blocking malware. Then we are going to understand bit about controlling web access using web filtering. Then we are going to configure 40 gates intrusion prevention system. And finally we are going to discuss about controlling application access. Now here is a short quiz to test your knowledge. What is the primary function of a 40 gate firewall? And your options are a to enhance Wi-Fi signal strength to block unauthorized network traffic and secure the network to improve internet browsing speed or to monitor social media activity. Now before we move into the session just a quick info guys simply learn has got CES certification which is certified ethical hacking course. You can master cyber security with EC council's CH course and also you're going to interact with accredit trainers. Finally you can think like a hacker or use AIdriven tools to protect systems from threats. You'll also learn to identify and stop cyber attacks before they cause harm. You'll gain hands-on experience with trusted ethical hacking techniques. This course is in collaboration with the EC council.

Let's get started. So guys, let us start with understanding what is exactly forgate. Forate is a powerful security device and it is used by organizations of all sizes to protect their networks from external and internal threats. For instance, an e-commerce company might use forigates to secure its website and customer data. Now, by deploying forigate, the company can configure its firewall to block malicious web traffic against DDoS attacks and inspect SSL encrypted traffic to ensure that no sensitive information is being transmitted in an insecure manner. So guys this is kind of very much important and you can see that this is also a part of the operating system and it is made by the company called as 14 and you can actually use this given tool uh I would suggest you using AWS. So you have this instance of you know so you have uh respective interface of 48 where you can create your instance and you can uh run that firewall. So there are different versions I'll just show you. So if you just type AWS48. So just click on this and u. So guys if you go to the AWS marketplace over here. So you have this respective uh foret. It is taking some time to load. Okay, let us wait for a couple of minutes and uh you can see you can uh just click on this video and get a brief idea regarding the respective uh architecture of how it is actually using the foret and if you see the respective thing it is uh it has the 40 gate VM and um on that virtual machine you can uh you know configure your 48 security you can configure your firewalls and uh let's say when You are setting a 40 gate let's say in a small office. So you might uh configure two interfaces. Let's say one for LAN which can be local area network and one for the van which could be wide area network. For example, if the VAN is connected to the internet and let's say the LAN interface connects to the office network, you would assign the VAN interface and IP address from your ISP and you can configure the LAN interface with your private IP range. For example, you can choose 192.168.1.1/24. Now, in addition to that guys, you could also configure static route uh which is going to direct all the internetbound traffics from LAN to the VAN interface. And this is going to ensure that all your office devices can communicate with the internet while traffic within the LAN remains local. Now, I'll give you a much more better scenario. See, in a typical office network, let's say you set up a static route on the 48. Let's say you are using AWS to configure uh the given uh 40 gate you have to ensure that any traffic from the LAN and the LAN IP address would be 192.168.1.0/24 and you could allow any uh traffic route basically 0.00/ any uh traffic coming all over there uh it could be routed through the VAN interface and which is connected to the ISP. Now uh let's talk about how you are going to set up the firewall policies. So if you just see this architecture in this respective video, let's consider a scenario where uh let's say organization is uh required to restrict the access to certain websites. For example, let's say social media and it allows internet access uh for work related activities. So you can configure a firewall policy which could define something like this. Let's say you have the incoming interface from the LAN and uh the traffic from the internal device basically that's your and uh let's talk bit about the outgoing interface which could be like uh the traffic to the internet which is basically uh the traffic to the internet. Then you have this source address. Uh it applies to all internal devices and you have this something called as destination address and uh it could be for all internet traffic service like it could be https or web traffic. Then you have the respective action. You could allow it for workrelated sites. You could block social media sites and uh this configuration uh helps the organization enforce an internet access policy by using the 40igate and also you can block social media websites. So most of you are pretty much aware that in your organization you cannot access certain uh websites for example like you cannot use Flipkart or you cannot access Instagram. So these all happen because the IT team of your organization sets up this firewall policy. But you would also have access to necessary business resources like your email, project management tool and cloud-based platform. Now guys, let me also tell you a scenario. Let's say you are in university and your university wants to allow access to its internal network only for registered students and staff. the university could integrate LDAP authentication with the 40 gate. So let's say when a student connects to the campus Wi-Fi, they are prompted to log in using their university credentials. And believe me, this was exactly the same thing in my university. Just login with your username and password. Now guys, once you're logged in, their access is granted according to the policy set in Forigate. And for enhanced security, the university could also implement two-factor authentication which requires a student to enter a code sent to their mobile phone in addition to their username and password. And also guys, the university's network administrator sets up an LDAP server in the 40 gate linking it to the institution's central directory. Student and faculty are authenticated using LDAP directory ensuring that only authorized users can access the network resources. So if you see this given um interface so this is how you basically work in the you know 40igate CLI. So let's say you're configuring any systems interface then you type edit and give the name then then you set the virtual DOM and then you set up your mode and what could be the mode either you could choose static or through DHCP or you know through triple POE and then you set your IP address then you set your security mode and then you shape your respective profile here you can also see you will also have to set up device identification you can also allow access all over here. You can ping to the SCPS and all those things. Then uh you can set up uh AP identity. You could set up EAP password also. You can set up your secondary IP also. So these are the respective configurations that you need to do and I would humbly request you do follow the 40 gate uh you know official documentation because most of the things you are going to get it from here since it is a proper product by organization. So whenever you are using any organization based product so you have to look into the official documentation all this and at the end you can see you are also setting an IP you are setting the allow access policy all those thing in your respective thing and this just looks like a simple instruction based command. So basically this looks like a set of instructions. All the networking guys would surely know it. And similarly if I just also talk about inspecting SSL traffic. Now guys let us talk to them. One of the most important aspect of our given 4 gate that is inspecting SSL traffic. Many organizations today use SSL to encrypt sensitive communications. However, SSL encryption can also be exploited by cyber criminals to hide malicious activities such as malware transmission. Forigate SSL inspection feature allows a device to decrypt SSL traffic and inspect it for potential threats. For example, a financial institution may use Forigate to inspect encrypted traffic to detect any malware or malicious code hidden in SSL connection to external sites. To configure SSL, the organization would set up deep inspection in Forigate SSL or SSH inspection settings and it enables the forigate to decrypt the traffic before inspecting it for threats like spyware, Trojans and any other forms of malware. Let me give you one example guys. Let's consider there is a user uh at a bank who actually wants to access uh an encrypted website using HTTPS. Now with SSL inspection enabled, Forigate decrypts the SSL connection, scans for threads, and then re-encrypts the traffic before it reaches the user's browser. And this is pretty much amazing. Forate also includes powerful antivirus feature that scans all incoming and outgoing traffic for the known viruses and malware. For example, in a corporate environment, employees frequently download attachments from the email. Now 40 gates antivirus feature can also set to scan these attachment for malware which ensures that malicious file is detected and blocked before it reaches to the employees device. Example of this could be a user let's say receives an email with an attachment that contains hidden virus and the antivirus feature of 40igate scans the file as it's downloaded identified the virus blocks it from entering the network and preventing any potential security breach. For example, a sales employee downloads an email attachment which turns out to be a Trojan and um you would actually be thanking to Forigate's antivirus feature which basically blocks it even before it reaches to the employees computer and so much importance of this is there when you want to safeguards an organization's network. Also guys let me tell you another scenario. Let's say guys uh your company wants to restrict employees access to non-workrelated websites to increase the productivity. Now you can actually use photogates web filtering and organization can block access to categories like social media, gaming or any other content which is restricted by company's organization. where filtering a profile could could be configured to block sites in social media category while you could allow access to productivity sites like Google Docs and Microsoft teams. You can apply this policy and uh the administrator would navigate to the security profiles, apply the web filter, is going to create a new profile that is going to block the social media and then apply to this profile to the relevant firewall policy and this ensures that the employee can't access Facebook or Twitter during work hours but can still use internet for work rellated activities. Let's say an employee tries to access Facebook during work hours. Then forgate web filtering is going to block the site ensure that the employee remains focused on the work and also on the task without any unnecessary distraction. And these are some of the most important things which an organization looks for. Now let us also discuss bit about configuring your footigates uh intrusion prevention system. So IPS as as we all know is crucial for detecting and blocking network based attacks like buffer overflows or SQL injection. For example, a retail company could use Forigate intrusion prevention system to monitor and block traffic uh attempting to exploit vulnerabilities in their e-commerce website. So by enabling IPS forigate can detect and stop attacks like DOS, ransomware or malware before they impact the company's operations. The IPS identifies is as a suspicious pattern in the network traffic attempt to exploit a known vulnerability in the website's content management system. Forigate blocks this traffic in real time preventing an attack that could also compromise sensitive customer data. And this forigates application control feature helps prevent any unwanted applications from running on the network. For instance, a company might want to block the use of file sharing applications like bit torrent or restrict access to non-workrelated streaming services. So network administrator can create an application control profile and the company can identify and block these specific applications based on their signature or behavior. For example, the company could apply an application control profile that blocks applications like Skype, Bit Torrent or Spotify and to increase the productivity and also they want to direct to the apps like Slack and Zoom. Now this is actually going to ensure that employees only use applications necessary for their work improving network security and performance. Let's say an employee attempts to use Bit Torrent to download a very large file during work hours. Forigate application control profile could block the traffic and ensure that company bandwidth is solely used for business purposes. Now guys in conclusion I want to say that forate actually provides a comprehensive suit of security features which is designed to protect against variety of cyber threats. So by properly configuring interfaces, firewall policies, user authentications, SSL inspection and malware blocking, web filtering and also applying IPS, businesses can ensure that their network remains secure, efficient and free from any disruptions caused by any malicious activity. Each of these features play a very critical role in safeguarding the organization's infrastructure while maintaining smooth operations. So that was all for today's video guys.
