Ways to Secure Your Wi- Fi Network and freeloaders alike. So what do you do? Follow these tips and you'll be well ahead of most home Wi- Fi users. Nothing will make you 1,0. Crafty social engineering schemes are tough to beat. But don't make it easy on them; protect yourself with these steps. Time- Tested Wi- Fi (and All Around) Security. Change Your Router Admin Username and Password. Every router comes with a generic username and password—if they come with a password at all. You need it the first time you access the router. After that, change them both. Immediately. The generic usernames are a matter of public record for just about every router in existence; not changing them makes it incredibly easy for someone who gets physical access to your router to mess with the settings. If you forget the new username/password, you should probably stick to pencil and paper, but you can reset a router to its factory settings to get in with the original admin generic info. Change the Network Name. The service set identifier (SSID) is the name that's broadcast from your Wi- Fi to the outside world so people can find the network. While you probably want to make the SSID public, using the generic network name/SSID generally gives it away. For example, routers from Linksys usually say . That makes it easier for others to ID your router type. Give your network a more personalized moniker. It's annoying, but rotating the SSID(s) on the network means that even if someone had previous access—like a noisy neighbor—you can boot them off with regular changes. It's usually a moot point if you have encryption in place, but just because you're paranoid doesn't mean they're not out to use your bandwidth. Fortunately, like the iOS. For full-bore protection—like making sure your own software doesn't send stuff out over the network or Internet without your permission—install a firewall. It's the single most important thing you must do to lock down your wireless network. Navigate to your router's settings (here's how) and look for security options. Each router brand will likely differ; if you're stumped, head to your router maker's support site. Once there, turn on WPA2 Personal (it may show as WPA2- PSK); if that's not an option use WPA Personal (but if you can't get WPA2, be smart: go get a modern router). Set the encryption type to AES (avoid TKIP if that's an option). You'll need to enter a password, also known as a network key, for the encrypted Wi- Fi. This is NOT the same password you used for the router—this is what you enter on every single device when you connect via Wi- Fi. So make it a long nonsense word or phrase no one can guess, yet something easy enough to type into every weird device you've got that uses wireless. Using a mix of upper- and lowercase letters, numbers, and special characters to make it truly strong, but you have to balance that with ease and memorability. Double Up on Firewalls The router has a firewall built in that should protect your internal network against outside attacks. Activate it if it's not automatic. It might say SPI (stateful packet inspection) or NAT (network address translation), but either way, turn it on as an extra layer of protection. For full- bore protection—like making sure your own software doesn't send stuff out over the network or Internet without your permission—install a firewall software on your PC as well. Our top choice: Check Point Zone. Alarm PRO Firewall 2. At the very least, turn on the firewall that comes with Windows 8 and 1. Turn Off Guest Networks. It's nice and convenient to provide guests with a network that doesn't have an encryption password, but what if you can't trust them? Or the neighbors? Or the people parked out front? If they're close enough to be on your Wi- Fi, they should be close enough to you that you'd give them the password. Some even block ads. A VPN is a smart bet for all Internet users, even if you're not on Wi- Fi. As some say, you need a VPN or you're screwed. Check our list of the Best VPN services. Update Router Firmware. Just like with your operating system and browsers and other software, people find security holes in routers all the time to exploit. When the router manufacturers know about these exploits, they plug the holes by issuing new software for the router, called firmware. Go into your router settings every month or so and do a quick check to see if you need an update, then run their upgrade. New firmware may also come with new features for the router, so it's a win- win. If you're feeling particularly techie—and have the right kind of router that supports it—you can upgrade to custom third- party firmware like Tomato, DD- WRT or Open. Wrt. These programs completely erase the manufacturer's firmware on the router but can provide a slew of new features or even better speeds compared to the original firmware. Don't take this step unless you're feeling pretty secure in your networking knowledge. Turn Off WPSWi- Fi Protected Setup, or WPS, is the function by which devices can be easily paired with the router even when encryption is turned < spanon,> because you push a button on the router and the device in question. Voila, they're talking. It's not that hard to crack, < spanhowever,> and means anyone with quick physical access to your router can instantly pair their equipment with it. Unless your router is locked away tight, this is a potential opening to the network you may not have considered.'Debunked' Options. Many security recommendations floating around the Web don't pass muster with experts. Thanks to Stanford Ph.D. A community-built site of hints and tips on using Apple's new Mac OS X operating system. That's because people with the right equipment—such wireless analyzer software like Kismet or mega- tools like the Pwnie Express Pwn Pro—aren't going to let the following tips stop them. I include them for completion's sake because, while they can be a pain in the ass to implement or follow up with, a truly paranoid person who doesn't yet think the NSA is after them may want to consider their options. So, while these are far from foolproof, they can't hurt if you're worried. WiFi running a bit slow lately?

Don't Broadcast the Network Name. This makes it harder, but not impossible, for friends and family to get on the Wi- Fi; that means it makes it a lot harder for non- friends to get online.

In the future, when someone wants to get on the Wi- Fi, you'll have to tell them the SSID to type in—so make that network name something simple enough to remember and type. The SSID is not so much as invisible as it is camouflaged.)Disable DHCPThe Dynamic Host Control Configuration Protocol (DHCP) server in your router is what IP addresses are assigned to each device on the network. For example, if the router has an IP of 1. DCHP range of 1. 92. IP addresses it would allow on the network. You can limit the range so (in theory) the DHCP wouldn't allow more than a certain number of devices—but with everything from appliances to watches using Wi- Fi, that's hard to justify. For security, you could also just disable DHCP entirely. That means you have to go into each device—even the appliances and watches—and assign it an IP address that fits with your router. Again, keep in mind, anyone one with the right Wi- Fi hacking tools and a good guess on your router's IP address range can probably get on the network even if you do disable the DHCP server. Filter on MAC Addresses. Every single device that connects to a network has a media access control (MAC) address that serves as a unique ID. Some with multiple network options—say 2. GHz Wi- Fi, and 5. GHz Wi- Fi, and Ethernet—will have a MAC address for each type. You can go into your router settings and physically type in the MAC address of only the devices you want to allow on the network. You can also find the . If you see items without a name, check its listed MAC addresses against your known products—MAC addresses are typically printed right on the device. Anything that doesn't match up may be an interloper. Or it might just be something you forgot about—there is a lot of Wi- Fi out there. Turn Down the Broadcast Power. Got a fantastic Wi- Fi signal that reaches outdoors, to areas you don't even roam? That's giving the neighbors and passers- by easy access. You can, with most routers, turn down the Transmit Power Control a bit, say to 7. Naturally, all the interlopers need is a better antenna on their side to get by this, but why make it easy on them?

VPN Setup Tutorial Guide - Secure connectivity for sites and mobile users, IPSec, SSL, PPTPA VPN (Virtual private network) is a secure connection between two or more endpoints. It can also be seen as an extension to a private network. There are two key types of VPN scenarios, Site to Site VPN and a Remote Access VPN. This would enable both sites to share resources such as documents and other types of data over the VPN link. Remote Access VPNIn a remote access VPN scenario which is also known as mobile VPN a secure connection would be made from an individual computer to a VPN gateway. Step By Step Guide To Setup Windows 7/Vista VPN Client to Remote Access Cisco ASA5500 Firewall. Please follow these steps to configure Windows LP2T/IPsec client for. How To Setup A PPTP VPN In Windows Server 2008. A VPN (Virtual Private Network) creates a secure tunnel across the Internet between you and your office, a VPN. This would enable a user to access their e- mail, files and other resources at work from where ever they may be, providing they have an internet connection. There are two common forms of technology that exists in remote access VPN known as IPSec and SSL that are covered further below. Why have a VPNA VPN saves organisations \ companies from renting expensive dedicated leased lines, VPN's give the ability for users to work from home and saves cost on resources such as e- mail servers, file servers, etc, as all these can be accessed on the VPN connection at the central site. A real world example would be if a company was split into two sites (When referring to sites we mean offices), the main site in the US and a smaller site in the UK. The US site has already a full network and storage infrastructure in place which consisted of active directory, an exchange server, file server and so on. The UK site only consisted of a small number of users, let’s say 1. To make this particular scenario cost effective a VPN connection from site to site would be the best solution. Providing a VPN tunnel from the UK site to the US site would save costs from having to install another network infrastructure, exchange server, active directory server and so on. As the US site would already have administrators maintaining servers and the infrastructure and can now maintain the VPN connection as well as other resources would prove another area where savings would be made. Another cost saving scenario to the above example would be to close the UK site down where employees based in UK could work from home. A remote access VPN scenario would be suited if the 1. UK based office. In this case they would just require an internet connection and a configured VPN client software enabling them to securely connect to their corporate network in the US. If they were using SSL VPN then they would not even require a configured client side software, they would just require the URL address to connect to the VPN portal. So VPN’s provide a superb and cost effective solution for companies with several branch offices, partners, and remote users to share data and connect to their corporate network in a secure and private manner. The latest version of UsenetServer VPN client is now available. Download the new software now to experience the new streamlined look and feel, tailored protocol. Setting up our PPTP VPN service on Windows 8.1 should take 5 minutes with these step-by-step instructions. Note: These instructions are specifically for Windows 8.1. A virtual private network (VPN) is a way to use a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with. The best VPN software with the highest security and best speeds. Download the IPVanish software with mobile apps, Windows and Mac applications. However sending data via a VPN tunnel encapsulates all data packets providing high level of security. If packets which were sent securely over the internet were sniffed, they would be unreadable and if modified this would also be detected by the VPN gateway. Using PPTP, remote users can access their corporate networks securely using the Microsoft Windows Platforms and other PPP (Point to Point tunneling Protocols) enabled systems. This is achieved with remote users dialing into their local internet security providers to connect securely to their networks via the internet. PPTP has its issues and is considered as a weak security protocol according to many experts, although Microsoft continues to improve the use of PPTP and claims issues within PPTP have now been corrected. L2. TP combines the functionality of PPTP and L2. F (Layer 2 forwarding protocol) with some additional functions using some of the IPSec functionality. Also L2. TP can be used in conjunction with IPSec to provide encryption, authentication and integrity. IPSec is the way forward and is considered better than the layer 2 VPN’s such as PPTP and L2. TP. IPSec (IP Security)IPSec operates on layer 3 and so can protect any protocol that runs on top of IP. IPSec is a framework consisting of various protocols and algorithms which can be added to and developed. IPSec provides flexibility and strength in depth, and is an almost perfect solution for securing VPN’s. The only drawback is IPSec requires setting up on the corporate network and on the client end and is a complex framework to work with. IPSec is used for both site to site and remote user connectivity. SSL VPN (Secure Socket Layer)SSL VPN provides excellent security for remote access users as well as ease of use. SSL is already heavily used such as when you shop online, accessing your bank account online, you will notice an SSL protected page when you see the “https” in your browser URL bar as opposed to “http”. The difference in using SSL VPN to IPSec is with IPSec a remote user would require client software which would need installing, configuring and sometimes troubleshooting. However with SSL there is no client software if a user was using the SSL portal. The portal is a GUI interface that is accessed via a web browser and contains tools and utilities in order to access applications on the network such as RDP and Outlook. SSL can also imitate the way IPSec works via a lightweight software. If a user required client SSL software, it can be installed with very little effort via a browser which simplifies the process in securely accessing to the corporate network. Using SSL VPN would mean thousands of end user’s would be able to access the corporate network without the support of an administrator and possible hours of configuring and trouble shooting, unlike IPSec. The end user would just need to know the address of the SSL VPN portal. Another advantage is they can do this from any computer as they do not have to rely on a configured client side software. Advantages and Disadvantages using a VPNAdvantages. VPN’s eliminate the need for expensive leased lines. Historically T1 lines have been used connecting office locations together in a secure manner. If the office locations are further away, the cost of renting these least lines can be unbearable. A VPN though, only requires you to have a broadband internet connection, and so avoiding paying a hefty sum of monthly rental on dedicated leased lines. VPN’s are also a replacement for remote access server’s and dial up network connections although rarely used anymore. Having many branch offices over the globe requires many leased lines, and so does not scale well. Each office would require a leased line to all other offices. VPN’s connecting via the Internet is a far more scalable solution, as opposed leased lines. Through the use of link balancing and link bonding VPN's can use two or more internet connections, so if one connection at your company had a problem all VPN traffic can be sent over the remaining connections, and will automatically use the original connection when it is back up again. Disadvantages. You have to remember though, having a VPN means having to rely on the Internet, and having to rely that your ISP (Internet Service Provider) is reliable, although this problem can be reduced by having two or more ISP’s and using the 2nd in a VPN failover scenario. IPSec is chosen as the example because it’s the most commonly used technology and is known to be a solid, robust and secure VPN technology. You may be new to all the VPN terminology, so clicking on the links in this VPN article will give you a good understanding on meanings within the below guide. Basics in setting up a site to site VPN with IPSec. Below covers what is required to set up a VPN connection on a VPN gateway with IPSec. It is not really aimed at a specific vendor and is fairly general. First you would decide how your going to authenticate both VPN peers to each other. Either select a Pre- shared key or install a digital certificate. This is used for authentication and to ensure the VPN gateways are authorised. This would prove their identities to each other. Both gateways must use the same type of credentials, so either both use pre- shared keys or both use digital certificates. Also if you are using pre- shared keys, then both keys would have to match. Phase 1. VPN's are configured and processed in two phases, phase 1 and 2. In phase 1 using Main mode or Aggressive mode you will set up a secure and encrypted channel, to protect your phase 2 negotiations. You will need to specify both gateway addresses. So you would specify the address of the local VPN gateway and you would also specify the address of the remote VPN gateway. You can either specify an IP address or a domain name. On some VPN gateways you could also specify an e- mail address, or if you use a digital certificate you could specify the certificates subject field. Main mode or aggressive mode can be selected depending on which one you would want to use. Main mode is more secure, but slower than aggressive mode. In Main mode peers exchange identities with encryption, and Aggressive mode, although faster exchanges identities without encryption. Main mode is the more commonly used. Aggressive mode is typically for when one or both of the VPN gateway's have a dynamic IP address. Specify whether to use Nat- Traversal. This is selected if your VPN gateway is behind a NAT device. Also specify whether you want both peers to use IKE keep- alive. This ensures that if a VPN gateway’s interface is not responding it will failover to the second interface. This is true when your ISP goes down and your secondary interface is a backup ISP. This includes the type of encryption, authentication and how long your security association will last. Sha. 1 is the stronger authentication algorithm. AES is the strongest protocol. You can specify a limit before your SA expires, which will add more security to your VPN if your keys have been hacked. Although this will also have a slight affect on performance as well. You will need to specify a Diffie- Hellman key group, usually 1, 2, 5 or 1. You can optionally set up extra transform sets if needed. There is a bug detected in Microsoft Internet Explorer 8, which creates problem to open links in a new tab or a new window.
