What do you know about Physical Security ?
<p><strong>Hello everyone my name is vijay kumar Devireddy and i am glad to have you back on my episode 88 today we're going to discuss about Physical security.Physical security is really important to your organization's network security.After all, if an attacker is able to touch your network,your server, or your work stations,they can take control over those devices and do whatever they want with them.While we've been talking a lot in this course about all of the logical protections you can put in place,things like firewalls and intrusion detection systems,router ACLs, passwords, encryption,and all sorts of things like that,our physical security is just as important.Now, physical security is usually broken down into three main areas.We have the perimeter,we have the building,and then we have the room itself.So when I start talking about the perimeter,I'm talking about, as I approach your building, what is in my way?Are there fences?Are there guards?Is there some sort of vehicle access point?All of those type of things, that's our perimeter.What keeps us at bay and away from the building? Next, we get to the building security. Is the front door unlocked? Can I walk right in? Do I have to show my ID? Do I have to check in with somebody? What are the different controls you're putting in place to secure that building?And then finally we have the security of the room where your equipment is located.Now, if this is an office, this is going to be someplace that people actually work, and so people have to be able to get in there to access those terminals.How are you keeping unauthorized people out of those offices?And if you're dealing with a server room or a networking closet, those are places that people don't normally work inside of.And so when nobody's in there, we should be locking those using some sort of locking mechanism,whether that's a door lock, an electronic lock,or some other mechanism.Now, we'll talk about that all inside this section of the episode.</strong></p> <p><br></p> <p><br></p>

Other Wireless Technologies that you wanted to know about.....
<p><strong>Hello everyone welcome to the show "Ethical Hacking" episode 87 today we are going to discuss about We just spent a lot of time talking about wireless networks, but there are other wireless networks out there besides Wi-Fi.These include things like Bluetooth,RFID, Near Field Communication, cellular,GPS, and satellite communications.Previously, we've talked about some vulnerabilities with Bluetooth.I want to remind you of two big terms when it comes to Bluetooth.This is bluejacking and bluesnarfing.I'm covering these again because I guarantee you're going to get at least one question on test day about either bluejacking or bluesnarfing really loves to ask that for some reason.Bluejacking is the sending of unsolicited messages to Bluetooth-enabled devices such as mobile phones and tablets.Bluesnarfing, on the other hand,is the unauthorized access of information from a wireless device through a Bluetooth connection.So, to simplify this for the I want you to remember this.Bluejacking sends information to a device where Bluesnarfing takes information from a device.If you remember those two things,you'll do great on the exam.Also, when it comes to Bluetooth,remember you don't want to allow your device to use the default PIN for its pairing operations You should always change the PIN to something more secure than 1234 or 0000.Next, we have Radio Frequency Identification or RFID.RFID devices have an embedded radio frequency signal that's used to transmit identifying information about the device or the token to a reader that's trying to pick it up.RFID refers to a large category of devices and technologies,but, for the exam, the specifics of RFID are not that important.Instead, you need to focus on the fact that RFID devices can send information from a card to a reader to provide authentication or identification.For example, one of the most common devices that we use RFID for is a card that looks like a credit card,and can be used as part of your alarm system or door access system.So, with these cards, you can swipe your card over the reader, and it identifies you and allows you to enter the building.Because there are so many different types of RFID devices, RFID can operatein either very close environments or very far environments.It can be as close as 10 centimeters from the reader or as high as 200 meters from the reader depending on the particular device and technology in use.Because of that large distance,RFID is subject to eavesdropping,the ability to capture, replay, and rebroadcast its radio frequency as part of a larger attack.To minimize the ability to eavesdrop on RFID, an idea called Near Field Communication was invented.Near Field Communication or NFC allows two devices to transmits information when they're in close proximity to each other.This occurs using an automated pairing process and transmission process of that data.For example, some cellphones have the ability where you can touch the cellphones together to pass photographs back and forth.Other uses of NFC are common place in payment systems.For example, I have an iPhone,and I can hold it over a credit card terminal to pay with my credit card that's linked through Apple Pay.This is an example of a Near Field Communication device.Just like RFID, we do have to worry about the possibility of interception of that wireless information though because it could be replayed and rebroadcast Now, luckily for us, NFC does require the devices to be very close for the communication to work.</strong></p> <p><br></p>

Wire less Attacks that you need to be aware of.
<p><strong>Hello everyone welcome to the show "Ethical Hacking" episode 86 today we are going to discuss about So we've talked about securing our wireless networks.Let's now spend a few minutes talking about the different types of attacks that focus on our wireless networks.The first is war driving.War driving is the act of searching for wireless networks by driving around until you find them.You could try this tonight. You can go sit in the backseat of your car,have your friend or your wife,drive you around the neighborhood and see which networks you can connect to.That's the idea here.They're simply going to drive around and hunt for networks.Now the attackers here are going to use different tools to do this.They can use wireless survey tools or other open source attack tools, but the common theme here is just finding out what networks are around and where you can access them from.Why would an attacker want to find open wireless networks or networks that they can get on to?It's not necessarily to attack your network,but it's to attack other networks through your network.So that way if they are doing some hacking or something like that,it traces back to your home and your home network,as opposed to tracing it back to them.The next type of attack is called war chalking.War chalking is the act of physically drawing symbols in public places to denote the open, closed, or protected networks that are in range.It gets its name because in the early days,people would actually take chalk and draw on a telephone pole different symbols to tell other people what it is.Now an example of this might be as you're doing a war driving,you might find an open network.If you did, you could find a telephone pole nearby,you can mark it down with a symbol like this.We have two open half circles faced back to back with the SSID of it written above them and the number below to signify the bandwidth of the network.Afterall, attackers can be nice people too.And they like to share their findings with others and they wouldn't want somebody else wasting their time looking for a network,only to find it has low bandwidth.So by marking that down,you can help other people avoid that network.Now in addition to open networks, you may find closed networks If you find a closed network,it's going to be a closed circle with an SSID written above it and bandwidth written below it.This tells us that network has some kind of encryption,it's closed,but we haven't quite figured out the password yet.Now if we do figure out the password,we can actually use this other symbol.We have the closed circle,we have the SSID on the top left left,we have the password on the top right,and the bandwidth below it.Inside the circle we might write something like W or WEP or WPA2,so people know what type of encryption they need to connect to that network.Now as I said war chalking is not nearly as popular as it used to be.In fact we don't really see a lot of these symbols around in the city anymore.Instead, most of this is being done digitally. This is being done as part of websites or other apps that hackers use and share their finds,so people know what other kind of WiFi is out there.The next attack we have is known as an IV attack.An IV attack occurs when an attack observes the operation of a cipher being used with several different keys and they findthis mathematical relationship between those keys to determine the clear text data.Now I know that sounds really complicated,but the good news is you don't have to do the math to do it.There's programs that do it for you.This happened with WEP because of that 24 bit initialization vector.It makes it very easy to crack WEP because there's programs that do it for us.</strong></p> <p><br></p>
