HI MY NAME IS SHE HAD SOME teach ethics.
Welcome you all to Cisco firewalls course.
In this video we will cover the topic of a Cisco firewalls as a overview by the end of this video.
You will be able to understand the basic features of Cisco firewalls is a and how they work and how
these can be implemented within your network.
So let's start as we discussed earlier firewalls have many different features and types and brands.
We will focus here on the Cisco a is a firewall which is the main focus of our course here.
This is case a family of security devices protects corporate networks and data centers of all sizes
so they have solutions for all sizes.
They provide users with highly secure access to data and network resources any time anywhere.
There is a cool line stands for adaptive security appliance OK which is actually the name of the software
of the Cisco firewalls.
OK.
So it is a stands for adaptive security appliance disfigured or picture actually represents a sample
of Cisco as a products.
They have many products actually this is just a sample.
OK.
They have many many different models.
Depends on the size and security requirements.
OK.
So let's move to the next slide.
All right.
The main serious product here will focus on is the Cisco fifty five nine fifty five hundred X which
is the main product of the Cisco is a firewalls and these products are considered a next generation
firewalls which we discussed earlier in a previous video
right.
So mainly those firewalls fifty five hundred help you balance security effectiveness with productivity
and the solutions offered by Cisco is a 50 500.
It's a combination between an industry's most deployed states full firewalls with a comprehensive range
of some features of the next generation firewall services including web security so you can implement
a web security or even a security on a cloud and intrusion prevention system which we call on IP s a
comprehensive protection from threats and advanced malware.
So mainly the Cisco is a 50 500 serious the next generation firewall intelligence firewalls they combine
both basic firewalls feature plus an intrusion prevention system and protection from malware and with
security I have included here a link to Cisco products which you can explore and read if you need more
information on a next generation firewalls from Cisco so you can click on this link and explore how
these products can protect your networks from different types of risks or security breaches.
OK so let's move on.
All right.
In this slide I want to explain the difference between a dedicated Cisco firewall and a router with
a firewall features actually instead of using a Cisco dedicated appliance you can use even a router
with some software firewall ing features.
So we have two options.
Either a dedicated firewall appliance or a Cisco router with a firewall capabilities so which one is
better use a to squeeze a firewall or a router with a firewall capabilities.
Actually it depends on your requirements and your network complexity.
All right.
And of course on your budget if you buy a dedicated firewall appliance it will cost more.
Spend a little money Cisco firewalls can range from five k five thousand dollars and above right.
So it depends on your network topology infrastructure and of course on your budget right.
So which one is better.
Again the difference that the router with a firewall capability is considered actually a software approach
which means you have a rather it provides you with a routing functions and capabilities plus a firewall.
Features that indicated IO is firewall which which is the is a firewall is a hardware based approach
which of course provides better and faster performance because as we mentioned later any solution based
on hardware has a better performance and a faster performance because you have dedicated hardware for
this job.
All right so let's look at these figures and instead of having this Cisco is a firewall between your
internal network and the Internet you can have a router with a firewall capabilities instead of this
dedicated firewall.
OK
OK so let's summarize what are the features of Cisco firewalls which are the Cisco is a he is the features
list and summary.
All right.
So General firewalls availability or the main features for the Cisco firewalls.
They are a standalone appliance separate appliance dedicated they are made small and mid-sized.
Depends on your business side.
The appliances are designed for extended temperature range operation in industrial or critical infrastructure
environment.
Actually firewalls from Cisco can fit in any car in any type of industry right.
Of course the improve security at the Internet edge.
They have high performance and throughput and you can even deploy a virtual instance for enterprise
class security.
So your hardware firewall is a you can even use it as a virtual appliance.
So one physical interface for example on the firewall.
You can divide it into many or several virtual appliance which is a cool feature actually.
All right.
Here is a summary of the features of the firewalls from Cisco clustering and high availability.
We will discuss this later in a later video in a future video.
What's me.
What it means by clustering clustering actually means you can have like a high availability very easy.
You can have a main firewall and actually a standard by firewall so is the main firewall sales the despair
one will function of course Cisco as if our roles are all next generation firewalls which include an
intrusion prevention system the work at the application layer which is layer 7 so you can protect your
web based traffic each TTP or TTP s or even SDP traffic Cisco firewalls can even provide you with a
routing capability that can act as a router or as a switch.
We will discuss also this subject later in future with you.
How Cisco is a firewalls can act or operate as a router or a switch firewalls from Cisco include built
in network profiling so they have built in profiles for the measure.
Security risks they can protect you from the measure and well-known security risks so they have built
in network profiling which will make your life easier actually instead of starting everything from scratch
you are in for a drink which is Internet or Web based security and they have also a VPN identity or
identity policy and control you can establish a VPN using a Cisco is a firewall.
OK
all right so let's move on the last slide here.
Why we choose a Cisco a is a firewall.
We have different brands different many types of firewall firewalls.
Why would you Cisco specifically Cisco is a leader in the market action since 40 years
the products of Cisco are very stable with excellent performance compared to other products on the market.
They have a minimal performance issues so very few customers actually complain about some performance
issues.
With with the Cisco AC firewalls they are very possible for this fast versatile
and these actually are reviewed by most of the customers.
It's just like the Cisco Systems.
OK the more than Cisco is a which they have a capability or a module called a fire power it's a separate
module that you can add to that Cisco is a firewalls this module can increase the Internet edge defense
dramatically it's very intelligent module that you can add to the Cisco is a to increase your Internet
security plus Cisco fighters are very easy to use.
The are friendly the interface is very friendly.
You don't have to struggle to figure out how they work.
They make your management tasks freely simple and easy
and as I said Cisco's solutions can fit any sized organization starts from small to medium to large
sized enterprise and they are been in the market for the past 40 years.
So Cisco actually hasn't lost its grip that's on sort of these video thank you very much for watching.
In the next series of videos we will focus specifically on the firewall features of the Cisco ACE.
A thank you very much and see you in the next video.
