Cisco Router Selection

With the constant evolution and change of the Cisco Router selection, it can be a tricky task to keep up-to-date. Do you know the current models of routers and more to the point do you know which Cisco router to choose?

Like us and many other people you will have been stunned and confused when Cisco removed from it’s line up what was considered the standard for midsized networks the 2600 and 3600 series. It was not their robustness or capabilities that saw them on to the ebay listings of secondhand routers, in particularly the 3600 series which can still do just about everything its latest counterpart can do; What made these fall by the wayside was the limitations of the CPU and the inadequate RAM. With the growth of the Cisco IOS beyond what these could handle combined with the swell of the packet load of most networks these older routers can no-longer cut the mustard. Saying that, the Cisco 3600 series is still the router of choice for some people as they can be picked up very cheaply in the secondhand marketplace.

The Cisco ISRs

There is a Cisco ISR to suit everyone’s needs; from the 800 series for the small to medium-sized network right through large campus or high performance large network. These are more than just routers they now provide services like IPSec, VPN, firewalls, and VoIP.

To help illustrate how to choose which router for your network type, the above diagram from Cisco demonstrates perfectly the routers available and their suitability. The rules for choosing the correct Cisco router is not set in stone, however there are some general pointers that should help.

Home office or small office

For constant VPN connections of up-to 10 home workers with good performance and reliability then look no further than the Cisco 800 Series. They have the Cisco IOS including IPS, VPN, VLAN, QoS, NAC, and Firewall. There are many routers in the range including wireless options and ISDN and DSL applications.

Small Remote Office

For networks that have up-to 25 or so users, the Cisco 1800 Series routers are the best choice. This router is ideal if all you need is a router to connect your office to the Internet, VPN, firewall, and wireless.

Larger Remote Office

If you require more performance and up scaling that the Cisco 1800 Series can offer, then you should look to the Cisco 2800 Series. Ideal for up-to around 50 users for office Internet connectivity, robust VPN access, with redundant power supply, Gig-E ports, NM expansion slots and Call Manager Express. Having the NM card slot lets you add things such as a 36-port switch with PoE, a DS3 ATM, a 24-port VoIP module, an intrusion detection module, a network analysis module, or a Cisco Unity Express voice mail module. Wonderful!

Office of 100 Workers or More

Cisco 3800 Series routers are similar to the 2800 Series in that there are a lot of HWIC and NM options for them. But what sets them apart from the 2800 Series is the sheer performance of the hardware and the number of HWIC and NM card that you can put into them.

Large HQ Office or Campus

For very large campus or service providers, the Catalyst 6500 and 7200/7300 Series platforms are for you. Cisco calls these "service aggregation platforms." These are very high-performance networking platforms with a huge capacity for expansion.

There are many things to consider browsing safely and through an encrypted Virtual Private Network (VPN), not just to access porn or log onto Second Life as the opposite gender. It's your financial information and profession that could be at danger.

Anonymous Surfing is somewhat people should have the alternative to do without government or companies tracking their every click if they want to. The ability to use all the internet has to offer is great, but can you really feel safe if you are being watched? If you are being tracked at every click? It's kind of creepy but ISP's, advertising companies and a lot of organizations that steal and sell your all personal information for profit all can and do this.

Consider what would happen if your boss came to know your home IP address and searched the Internet for your postings and online activities by IP address. If you want to Unblock VOIP of your office or school, you should buy VPN.

I think people also have a right to privacy, and it is not evident from looking at your browser whether someone is monitoring you or not. There are millions of security cameras out there recording you everywhere you go in the offline world but people can usually see them and accept the loss of privacy for the trust that they are not going to get into any trouble or loose any personal information from them.

The only solution to all these problems is anonymous browsing with Virtual Private Networking. VPN provides you a shield of encryption against spies and hackers; and an untraceable IP address for anonymous browsing.

Apart from the security aspect a Virtual Private Network also lets you access restricted websites in your country or company. And unlike web proxies Virtual Private Networks are much faster and reliable.

For a successful VoIP rollout across an organization, several factors should be considered. The following precautions will help eliminate the most common VoIP security threats such as the distributed denial of service (DoS) attack, spams and frauds.

During VoIP configuration/installation, it is important to establish security infrastructure including firewalls, VPNs, etc., to be capable of supporting the advanced security requirements for VoIP and be voice optimized at the same time. The VoIP security protocols dynamically allocate ports during call setup, requiring opening and closing of ports at the security gateway on demand. The protocol required the voice traffic inspection at the network and application level to address the challenges of VoIP protocols in Network Address Translation (NAT) environments.

Similar to other services using network, there are critical security vulnerabilities being identified for VoIP. It is important to have the IP-PBX and IP Phone firmwares always updated and patched for the latest security vulnerabilities. Regular security assessments of your VoIP infrastructure provide identification and remediation of such security flaws to avoid attacks and prevent outages. Your IP-PBX is the heart of your VoIP infrastructure and it must be updated and patched as necessary.

Since the VoIP gateways, servers and phone can be configured remotely, backdoor and front door access is sometimes enabled for ease of configuration. It is recommended to properly secure any remote access and configuration capabilities to individual VoIP devices to eliminate any security breaches. It is important to note that the endpoint credentials and administrator passwords on such devices are a very common avenue for attacks. In general, disable any insecure remote access features, such as FTP and Telnet, and disable local administration and management features.

Internet Filter Bypass

If your VoIP traffic goes over the Internet, use encryption technologies like IPsec tunnels to secure the VoIP traffic. While many of the VoIP protocols include capabilities for encryption and authentication, most of them are optional. It is essential to establish secure tunnels for carrying the VoIP information streams (call signaling, call control and media) between sites.

Wherever possible, leverage VLANs to separate voice and data devices and traffic. This may have limited impact on security, however deploying VoIP devices on separate VLANs isolates data traffic from voice and signaling traffic and permits utilization of Quality of Service (QoS) capabilities.

When creating passwords for accounts, follow secure password guidelines such as making password long, using a combination of numbers and alphabets, not using common names, or same as the account numbers.

Router Functionalities
Firewall


Firewalls are ideal for home networks. They help in protecting home use computers by stalling the destructive efforts of other official websites and potential hackers. This software or hardware device filters the information coming through the internet connection, flagging the information that is not to be allowed through. You can find some such models at:


VPN Pass through


VPN pass through feature of routers allows traffic between the endpoints and does not support one of the endpoints. This feature is ideal for routers of home use or small office setups; they are less expensive than a router with full VPN that supports the endpoints.
DHCP server


Dynamic Host Configuration Protocol (DHCP) servers can be implemented for windows based system. The server automatically assigns an IP address to the computer’s TCP/IP stack software.
Wireless Access Point


The performance of your network will depend on signal strength of the wireless access point. Before you position it, find out the exact location from where it will give the maximum network range.
DSL Modem


Digital Subscriber Line modems are faster than regular modems and can use the existing phone lines. Both internet connection and phone lines for telephone calls can be used simultaneously.
Voice over IP gateway


VoIP routers have both wireless networking feature and telephone terminal adapters. With this feature the network can access both Internet and voice communications.
Protocols


These are formats for transferring data between the various devices. The protocols determine the various aspects of the data like compression types, delivery and retrieval by devices and error checking. The standard protocols differ in their various features, so in order to communicate with other computers correct protocols must be selected.



Internet Protocol (IP) enables unique addressing for computers.


When used with transport control protocol, it is referred as TCP/IP.


The newer IP version 6 is referred as IPv6. This version addresses 16 bytes in length.


DHCP: Dynamic Host Configuration Protocol assigns dynamic IP addresses to devices on a network.
Routing Protocols


The information packets have to be routed by a series of routers to get to its destination. Latest routers automatically exchange route information with other routers through the use of routing protocols.



While configuring the router on your own, you have to choose what types of routing protocol you have to install and configure.



RIP version-1: It is a dynamic protocol and automatically figures routing tables on its own, thus manual inputs are not required.
Encryption Standards


This feature configures the virtual private network, encryption hardware advanced integration modules and the network modules.

Data Encryption Standard - applies 56-bit key to 64-bit block of data. This is the most commonly used encryption standard. A single key is used which is very difficult to break.

Triple DES (3DES) - applies 3 keys in succession making it more difficult to break the code.



Advanced Encryption Standard (AES) will be the next encryption standard for commercial transactions in the private sector.

MD5

SHA 1
Modulation


There are many standards of modulation. The most commonly used types are:
QAM: Quadrature Amplitude Modulation, a dominant modulation technique for high speed digital signals.
CCK: Complimentary Code Keying is a modulation scheme to operate in data speeds up to 11Mbps in the RF band.
OFDM: Orthogonal Frequency division multiplexing modulation is used for even higher speeds of 54Mbps.
DSSS: Direct Sequence Spread Spectrum use wideband signals that are not easy to detect and resists jamming attempts.
Security


Today no home and office network is secure. To counter the hacking efforts of hackers, look for good built-in security functionalities. These will ensure that your system doesn’t slow down, those within the range of your wireless are not able to view your files, emails, instant messages, usernames and passwords. Depending on the security features you can also block spams, illegal activities with your internet connection and prevent loading of dangerous software.

This however doesn’t mean your network is completely secure.
Some steps that can be taken are:


Enable WEP, wired equivalent privacy encryption provides security to WLANS. The WEP keys encrypt the data stream.


Turning on WPA encryption. The Wi-Fi protected access adds on the authentication and encryption features WEP explained above.


TKIP, Temporal Key Integrity Protocol covers up for the encryption weaknesses of WEP.


WPA2 protection is the latest one and provides high level of protection.


Enable wireless MAC Address filtering.

WEP Encryption length


The WEP encryption is based on a combination of secret user keys and system generated values. The key encrypts and de-encrypts the data that is transferred between the access points and the clients. There are two versions:


The earlier version supported 40-bit encryption; the key length was 40 bits and 24 additional bits of system generated data, thus a total of 64 bits.


Easy decoding of 40 bit WEP encryption encouraged vendors to go in for 128-bit encryption. 128-bit encryption has a key length of 104 bits.

Antenna Type


The omni directional antenna of routers broadcast 360degrees around the router. Position them in such a way that you can make the most of the radiating signals.



External antennas can add strength significantly, thus giving a wider range and increased network performance when compared with the performance of in-built antennas.



Detachable antennas disable 802.11a lower band communications when detached. On attaching the antenna the lower band is enabled. Thus they can be screwed into the device and can be upgraded easily.



The third type is the internal integrated antennas. These antennas are built-in, and hence cannot be changed or directed.
Brand Name


Wireless routers are still evolving, and at this infant stage it will do good to stick to one brand. Switching between brands can lead to compatibility problems. Linksys and Netgear wireless routers are among the few companies that have the highest wireless router ratings a company can get.
Linksys


Linksys wireless routers are easy to install and are reputed to give good performance and signal range. The various features that the router supports are protection from hackers with NAT technology, VPN pass through, and can encrypt all wireless transmissions.

Have you heard about that new virus that just came out but you’re not worried because you have a firewall? A common misconception among computer users is that firewalls block viruses. But here is the scary news…they don’t!

A firewall is software-based or hardware-based protection that blocks malicious attacks on your computer from coming through over the internet. But don’t viruses come over the internet so a firewall should block them, correct? You’re right, but the difference is that viruses and spyware infect your computer by human interaction done on your part. Meaning, you might view an infected picture or visit a bad website, or open up an infected email for example. Anti-virus software protects you from these situations, but not a firewall.

So what is a firewall you ask? Computers have ports that they can communicate through…65,535 to be exact. A firewall will block communication to every one of those ports except the ones you specify it unblock. For example, if you connect to your company VPN from on your computer, you would only need port 1723 unblocked. By blocking all ports but port 1723, a hacker only has 1 port to try to hack through instead of trying to hack 65,535 ports. This just made his job MUCH harder!

The good news is with today’s technology you probably already have a firewall protecting your computer. Most routers (either wired or wireless) that connect to your broadband modem come with a firewall. By default, routers have the firewall turned on, but check the router settings to make sure it is currently protecting your network. If it’s not enabled, enable it and then specify the ports you want to have open.

What if you don't have a router? In Windows XP and Windows Vista, they both come with a software firewall installed. Software firewalls do the same thing as hardware firewalls but may not have the advanced features such as logging activity or notifying you if it suspects harmful activity. However, software firewalls are better than no firewall at all

.
I’ll install several firewalls on my computer so I’m protected better!! This is a myth and is not correct. As I previously stated, firewalls close all ports but ones you specify, adding another firewall to your network just means you have to specify on that firewall the ports you need open. So two firewalls doing the same thing will not protect you any better but just slow down your network since data being transmitted through your network is having to be looked at by both firewalls, therefore I highly recommend you make sure your not running two or more firewalls.

While I prefer hardware based firewalls because of the advanced features they have, I have seen some very good software based firewalls. Hardware firewalls I prefer are WatchGuard, SonicWALL, Untangle, Check Point and Netgear. While software firewalls I recommend are ZoneAlarm, Norton and McAfee. No matter who you choose, you can rest assured that you’re making the life of a hacker a lot harder!

Demand for mobile and remote access to business networks has increased dramatically.  Even the most basic virtual private network (VPN) technologies are so accessible and affordable that there is no good reason for failing to utilize them.  That said, the real question for businesses is which type of VPN to implement:  Standard IPSec (Internet Protocol Security) or secure-sockets layer (SSL)?

SSL is Best
Businesses that have limited budgets and/or those that do not share highly sensitive data may opt for a standard VPN because of cost; this technology is virtually free.  In fact, most operating systems have built-in VPN protocols, but you typically get what you pay for here.  Such protocols often rely on little more than usernames and passwords, they usually lack robust authentication and encryption components, and they can easily become open doorways into corporate networks.  Furthermore, standard VPNs require the deployment of software and clients – an administrative headache at best.

SSL VPNs use the same encryption protocols as many e-commerce sites and Web-enabled applications.  They are therefore more compatible with the networks through which your remote users connect.  Further, SSL is simple to install and leverages firewall ports already opened to secure Internet traffic, enabling users to connect to a network securely via a standard Web browser, without the need to install special software on the client (e.g., desktops or laptops).

SSL VPNs will support security policies that regulate access depending on the user, device or location.  SSL can also deny access if a less-than-secure situation is detected, such as a user logging on via an unsecured wireless LAN at a local coffee shop.  In a word, while SSL may cost more up front than standard VPN solutions, it pays for itself in reduced management costs and improved network security.

SSL Encryption for Data Protection

Through SSL and effective key management, IT managers and end-users alike can share information securely and conveniently.

Security of VoIP Network

The security of VoIP networks have been the subject of much debate. With internet hacking at an all-time high these days, VoIP users have every right to be concerned their user information, phone services or even their phone calls are being listened to. Because of this risk, individuals and businesses find this one of the stumbling blocks to VoIP implementation.

Since VoIP calls are made digitally, they are easier to tap into than a traditional phone line. So someone with the right access and knowledge can listen to what you have to say. While most residential VoIP users, unless they are sharing financial data, would find it embarrassing if they knew someone was listening to their calls, for businesses, tapping into their VoIP system could be disastrous.

No matter what the stakes are, privacy is important. Even though the thought of snooping into your business or residential VoIP network seems violating, it's a fairly simple task to ensure your VoIP's security.

The following are application choices for encrypting your VoIP network:

Zfone: Check out Zfone, which is software that secures your VoIP network by encrypting calls. They offer a free beta version which is easy to install and use. The downside is only calls made to other Zfone users are protected. Service Provider Encryption: Check with your VoIP service provider to see if they offer their own encryption software. Transport Layer Security & IP Security: Authenticate your server with Transport Layer Security (TLS) and IP Security (IPsec). These are two simple encryption methods for VoIP calls. TLS encrypts data transferred between two applications while IPsec encrypts information for the devices and their applications. Secure Real-Time Transfer Protocol: Authenticate Secure Real-Time Transfer Protocol (SRTP). SRPT protects VoIP calls by creating an encryption key for each call, without affecting call quality. Virtual Private Network: Enable Virtual Private Network (VPN) Encryption. While your business's VPN should come with a built-in encryption device, it will only secure data from gateway to gateway. Also, your LAN calls will require additional security. Session Initiation Protocol: Session initiation protocol is the standard choice for VoIP and other IP communications. VoIP network administrators are concerned with allowing SIP calls through a firewall while securing the network. SIP works with other protocols like HTTP and SMTP to integrate the much needed security measures. SIP trunking can securely connect SIP users with callers on a traditional phone system.

In summary, make sure your VoIP network uses one or more of the above mentioned encryption applications. Your personal or business information is only meant for those you want to share it with. Take the necessary steps to prevent your information from getting into the wrong hands. Contact your VoIP service provider today to ensure your VoIP network has a secure connection.

Demand for mobile and remote access to business networks has increased dramatically.  Even the most basic virtual private network (VPN) technologies are so accessible and affordable that there is no good reason for failing to utilize them.  That said, the real question for businesses is which type of VPN to implement:  Standard IPSec (Internet Protocol Security) or secure-sockets layer (SSL)?
