The Little Geeni

Today, more than ever, home networks are easier and less expensive to set up. At times, however, the knowledge needed for building a network is not accompanied by any guidelines on how to secure them.  In some cases, the guidelines are simply ignored. No matter what the case, that is a data disaster just waiting to happen.

You may have a thing about being paranoid about security. That is an excessive amount of concern that should be tempered. However, you should have a certain amount of caution. Security is much like medical insurance. You may not need it very often, but when you do need it, chances are you need it badly. If you don’t have it you may face dire consequences.

Wireless home networks are becoming increasingly popular due to their lower cost and flexibility.  However, the wireless network is particularly prone to security issues. In theory, someone that has a wireless enabled laptop can just drive by your house, get into your space and tap into your network. It’s not too much of a problem if all they do is steal a little bandwidth. However, if they happen to be malicious and clever, they will be able to implant a virus into your home network without you even knowing it!

Using the Internet has similar risks. However, in a case like that you usually have to download an attachment from someone you don’t even know to get infected. This scenario is easy to avoid. As a rule of thumb, if you do not know who it is from, do NOT open it. It could be a hacker with a virus. However, in the case of a wireless home network, you do not have to take any action to get infected. Even though you may be following good Internet file sharing practices, you are still vulnerable.

Even if you have a cabled network, it is possible for someone to break in while you are away. Most of these incidents will revolve around stealing property. But by infecting a computer a disgruntled employee, an angry person or a party to a lawsuit may use this as a way of getting revenge. What a better way to get revenge than to have your computer crash!

The solution is typically the same in either type of network. Practice the same good habits you use for Internet data sharing and magnify them. You must make sure that each computer on the network has a password that is required in order to gain access to the system. Leaving a system unprotected to just save a few seconds of inconvenience at home will expose your entire network to unnecessary risk.

One thing you want to do is change the password on your router often. The defaults for most of the popular vendors’ products are known by just about everyone who has the necessary skills to do harm.  Make it harder for them to inflict damage by following this simple step. Configure your wireless router according to the manufacturers’ instructions in order to prevent unauthorized access. Today, all wireless routers use WAP to prevent drive-by’s from accessing your system.

Most adults today would be astounded by the amount of computer knowledge a teenager has. Most are well meaning, but some young people have not yet learned how to use a home network securely. Some young people can master the techniques, but they do not yet have the common sense or the wisdom to know how to put these techniques into practice.

Treat your home network in much the same way as you would treat your credit cards. You wouldn’t just hand you credit card out to a stranger would you? Moreover, you wouldn’t tell that stranger your password would you? You would be broke in no time! Do not provide physical access or pass out information to anyone that you do not want to have access to it. This is often a short step from having them access your money. It is an even shorter step to your valuable home network as well as your data!

The facts of small and large business networking solutions are more or less the same. Importance of effective network installation service and reliable network security & support services cannot be denied for any type of business, irrespective of its size and scale. Every organization needs networking solutions and employs onshore or offshore team for handling the networking issues from time to time. Server down, Connectivity issues, and akin are some of the usual network related issues that distract a business working day on an average. All such problems are of high importance and must be corrected on first priority basis. So there is always a need for a networking engineer team with in-depth knowledge of the networking concepts and fair grasp of the practical know how, so as to address the issues with optimum speed.

 

Hiring a team of such a competency is always very expensive and probably not a feasible option for the small businesses. To the rescue are organizations with experts in networking solutions, who customize the small and large business networking solutions to your exact requirements. The cost effectiveness and durability of the network installation service and network security and other support services becomes something not to worry about. There are some key points one must ask oneself, while searching for a networking solutions team, as and when you decide to hire Network security & support services.

 

Which geographical location should be preferred while hiring a networking solution? (Neighboring, provincial or state-wide)?

What demographics would suit your requirements (income specific, etc.)?

What should be the strength of the Networking solutions team?

 

It’s better to have the team seated within the organization, as thus they will be better able to tackle networking issues of connectivity or server issues. They will be able to give a better backup solution. Networking solution team also has the competency of establishing extensive network security. Network security is of high importance for any organization that has the network installed. There are various types to establish network security. This depends on the requirements and the profile of the organization.

Cisco Networking:

Cisco Systems, Inc. (NASDAQ: CSCO, SEHK: 4333) is a multinational corporation with more than 63,000 employees and annual revenue of US$35 billion as of 2007. Headquartered in San Jose, California, it designs and sells networking and communications technology and services under five brands, namely Cisco, Linksys, WebEx, IronPort, and Scientific Atlanta.

Cisco Certifications:

Cisco Career Certifications are IT professional certifications for Cisco products. The tests are administered by Pearson VUE (Prometric previously administered the test; but as of 1 Aug 2007, no longer does).

There are three levels of certification:

* Associate,

* Professional, and

* Expert.

Associate certifications:

* Cisco Certified Network Associate (CCNA)

* Cisco Certified Design Associate (CCDA)

Cisco certified network associate (CCNA):

Candidates have the option of gaining the certification by passing two tests (ICND1 640-822 and ICND2 640-816), or one single test (CCNA 640-802); the two-test option has the advantage of allowing the candidate to focus on certain subjects.

The certification is valid for three years; at that time a CCNA holder must either

* re-take the CCNA or ICND exam, or

* take and pass an exam for one of the Professional (e.g., CCNP) or Specialist level certifications (excluding the sales specialist exams), or pass the CCIE written exam.

These exams are known by their corresponding numbers. When the curriculum of the exam changes the exam number also changes. The current exam number for CCNA is 640-802 (from 15 Aug 2007). New ICND Part1 (640-822 ICND1) and ICND Part2 (640-816 ICND2) available from 15 Aug 2007. Part 1 by itself will give you a CCENT.

These exams are conducted by authorized test centers at a cost of $125 USD each for the ICND1 or ICND2 exams and $150 USD for the full CCNA exam.

There is also the Cisco Networking Academy, which brings the CCNA and CCNP curricula into traditional educational institutions in over 150 countries.Students enrolled in Cisco Networking Academy can request exam vouchers that allow them to take the retired exam for an extended period of time.

Cisco Certified Design Associate (CCDA):

The CCDA certification indicates an apprentice knowledge of Cisco network design. Individuals who have earned a CCDA are capable of designing switched or routed networks consisting of LANs, WANs, and various dial services. While a CCNA certification is not required to take the CCDA exam, Cisco recommends being familiar with CCNA material. Also recommended is knowledge of BCMSN.

Professional certifications:

* Cisco Certified Network Professional (CCNP)

* Cisco Certified Design Professional (CCDP)

* Cisco Certified Internetwork Professional (CCIP)

* Cisco Certified Security Professional (CCSP)

* Cisco Certified Voice Professional (CCVP)

Cisco Certified Network Professional (CCNP):

The CCNP is considered proof of having the ability to work with medium-sized networks (between 100 and 500 end devices) and with technology such as QoS, broadband, VPNs, and security-minded features. To acquire a CCNP one must possess a CCNA certification first and then pass three or four tests, depending on the path one chooses. The four tests path requires the candidate to pass the following tests:

* 642-901 BSCI: Building Scalable Cisco Internetworks (BSCI) – Deals with routing

* 642-812 BCMSN: Building Cisco Multilayer Switched Networks (BCMSN) Deals with switching

* 642-825 ISCW: Implementing Secure Converged Wide Area Networks (ISCW) – Deals with wide area networks

* 642-845 ONT: Optimizing Converged Cisco Networks (ONT) – Deals with using Qos to tune networks to work effectively with IP Telephony.

The BSCI and BCMSN tests can be taken as one single composite test known as the 642-892 Composite which covers subjects for Building Scalable Cisco Internetworks (BSCI) and Building Cisco Multilayer Switched Networks (BCMSN).

In order to retain the certification one must either re-certify or pass one of the CCIE written exams before the Professional certification expires. Additional resources and tools to aid in preparing for the certification are available on the CCNP Prep Center.

Cisco Certified Design Professional (CCDP):

The CCDP certification is an advanced network design certification provided by Cisco Systems, Inc. Candidates for the certification are tested for advanced knowledge of Cisco devices and the way to interconnect them. This certification is considered a professional level certificate by Cisco Systems. (The CCNA and CCDA are prerequisite.)

Cisco Certified Internetwork Professional (CCIP):

The CCIP certification is a professional certification covering the end-to-end protocols used in large scale networks.

To attain this certification tests must be passed in the areas of routing, BGP, MPLS and Quality of service.

Cisco Certified Security Professional (CCSP):

The CCSP certification is an advanced network security certification. Candidates for the certification are tested for advanced knowledge of various Cisco security products.

To attain this certification several tests must be passed in the areas of VPN, IDS, PIX firewall, Secure IOS, the Cisco SAFE, as well as having a CCNA or higher level certification (e.g. CCNP or CCIP).

The common practice is to take five exams which include one elective paper. The list of exams and elective papers can be found in the Cisco website.

Cisco Certified Voice Professional (CCVP):

The CCVP is a certification covering all aspects of IP Telephony/VOIP networks and applications.

To attain this certification, five tests must be passed in the areas of Quality of service, Cisco VoIP, IP Telephony Troubleshooting, Cisco IP Telephony, and Gateway Gatekeeper.

Expert-level certifications:

The expert-level certification is the Cisco Certified Internetwork Expert (CCIE). It is the highest level of professional certification that Cisco provides. There are 5 active CCIE tracks, as shown below. As of April 6, 2008 there are 16,335 people with active CCIE certifications in the world.

Cisco began its CCIE program in 1993 originally with a two day lab, later changing it to the one day format used today. Fewer than 3% of Cisco certified individuals attain CCIE certification, and on average will spend thousands of dollars and 18 months studying before passing. Many candidates build mock-labs at home using old Cisco equipment, selling it again to other candidates after passing. Alternatively candidates may rent “rack time” online and practice lab scenarios on Cisco equipment hosted on the Internet for that purpose.

Cisco refers to the CCIE as the “most respected IT certification”, and from 2002 to 2005 it was voted as such in CertCities magazine. It has also been voted the most technically advanced IT certification by CertMag, and is generally reported as the highest salaried certification in IT salary surveys.

The CCIE is comprised of a written exam and a “lab” exam (each in the specific area of the chosen track). The written exam is required to take the lab exam, and has a cost of $315 USD per attempt. Upon passing the written exam, the candidate is qualified to have a first attempt the lab exam for 18 months. If the first attempt is unsuccessful the candidate has 3 years from the date the written exam was passed to successfully complete the lab. If a candidate does not pass the CCIE lab in that time, they must pass the CCIE written exam again before making additional attempts at the CCIE lab exam. As many attempts can be made to pass the lab exam for up to 3 years after passing the written, so long as the first attempt is within 18 months. There is a minimum waiting time between attempts of one month.

The CCIE Lab is currently $1,400 USD per attempt and are offered only at ten Cisco lab exam locations worldwide. The locations are Bangalore; Beijing; Brussels; Dubai; Hong Kong; Research Triangle Park, NC; San Jose, CA; São Paulo; Sydney; and Tokyo. Some CCIE tracks do not have lab exams available at all locations. For example, the Storage Networking lab is available only at the Research Triangle Park, NC and Brussels locations. In addition, according to a survey by Cisco the average cost to prepare for CCIE certification is $9,050 as of April 2006, spent mostly on practice equipment and self study material.This is partially offset by the increased salary the certification commands, which a March 2007 Network World article estimates at 10% – 15% over similarly experienced engineers who do not have a CCIE.

The lab is an 8-hour hands-on exam designed to demonstrate that the candidate not only knows the theory, but is also able to practice it. Many prospective CCIEs need multiple attempts to pass the lab exam.

There are no formal prerequisites for the CCIE exam, but Cisco recommends one has at least 3 – 5 years experience in networking before attempting to become a CCIE. CCIE was the first Cisco Certified qualification, and as such there were no other certifications that could be taken prior. The development of the associate and professional certifications was due to recognition of the fact that a CCIE is overkill for many networking personnel, and also for the vast majority of businesses who employ such people, and that certifications needed to be offered at lower levels. Despite the development of the lower certifications, Cisco has chosen not to make them formal requirements for the CCIE certification.

It is possible to hold multiple CCIE certifications. This is done by passing both the written and the lab exam in a particular track. As of November 14th, 2007 there are 1,344 individuals who hold multiple CCIE certifications. Of those, 210 hold three or more CCIE certifications.

* CCIE Numbering

* CCIE Routing & Switching

* CCIE Security

* CCIE Service Provider

* CCIE Voice

* CCIE Storage Networking

* CCDE

CCIE Numbering:

Upon successful completion of the hands on lab exam, a new CCIE is awarded a CCIE number. The first CCIE number allocated (in 1993) was 1024, and has increased incrementally from there. A lower number indicates that the CCIE was awarded some time back, a higher number indicated a more recently awarded certification. As of February 2008, the highest CCIE number allocated was just over 20000.

Number 1024 was allocated to the first CCIE lab location, rather than to an individual, and featured as a plaque at the entrance to the lab. Number 1025 was awarded to Stuart Biggs, who created the first written exam and first lab exam. The first person to pass both CCIE written and lab exams was Terrance Slattery, who was consulting to Cisco at the time when the lab was being devised. Terry Slattery (CCIE 1026) was therefore the first CCIE who passed both exams, and the first CCIE who was not an employee of Cisco.

Any CCIE who obtains further CCIE certifications, is not awarded any further numbers, the new CCIE certification is awarded under the same number as the original.

CCIE Routing & Switching:

Routing and Switching is by far the most popular track with 16,355 certified individuals as of March 25, 2008. The certification covers a variety of networking concepts and protocols including but not limited to the following list

1. Routing and Switching

* IP services

* IOS user interfaces

* System management

* Network Address Translation (NAT)

* Network Time Protocol (NTP)

* Simple Network Management Protocol (SNMP)

* Remote Monitoring (RMON)

* IP Accounting

* Service Level Agreement (SLA)

CCIE Security:

The Security track concentrates on network security and covers subjects such as ASA, IDS, IOS security, and many others.

CCIE Service Provider:

The Service Provider track focuses on networking in the service provider industry. Subjects include Optical networks, DSL, WAN switching, Voice over IP, Content Networking, Broadband Cable and Metro Ethernet.

CCIE Voice:

The Voice track concentrates on voice solutions for the enterprise and includes subjects such as QoS, MGCP, Call Manager (Cisco’s VoIP PBX), Cisco Unity (Cisco’s Unified Messaging platform), Unity Express and IP Contact Center Express.

CCIE Storage Networking:

The latest addition to the CCIE certification tracks is the CCIE Storage Networking track. As the name suggests, the Storage Networking track concentrates on storage networking topics, such as Fibre Channel, iSCSI, FCIP, Intra VSAN Routing and FICON.

CCDE:

Cisco Certified Design Expert CCDE Assesses advanced Network Infrastructure Design Principles and Fundamentals for large networks. A CCDE can demonstrate an ability to develop solutions which address planning, design, integration, optimization, operations, security and ongoing support focused at the infrastructure level for customer networks.

Prerequisites for CCDE There are no formal prerequisites for CCDE certification. Other professional certifications or training courses are not required.

Recommended Training and Experience It is expected that the candidate will have an in-depth understanding of the topics in the exam blueprints, a minimum of seven years job experience, and a thorough understanding of networking infrastructure principles. Please view the written exam information page for more details.

Step One: CCDE Written Exam You must pass the two-hour, written qualification exam which covers advanced networking infrastructure design principles and concepts. Once you pass the qualification exam, you are them eligible to schedule the practical exam.

Step Two: CCDE Practical Exam The CCDE practical exam is still in development, however it will be an eight-hour exam that will test your ability to identify, manage, and create advanced solutions for large scale networks. You must pass the lab within three years of passing the written exam in order to achieve certification.

How can you can connect PC to switch with straight or cross-over cable, what is the difference between these two ways, Straight through cable vs Crossover cable? Why are their two types of cables? What do they do?Straight through cable means, the cable wire goes through straight, transmission wires over to the reception end. You use a crossover cable when you are connecting two PCs together directly (NIC to NIC). To connect Router to Router and Computer to Computer need Crossover and the usually the rest need Straight-through cable.

You use a straight-through cable when there is a hub, switch or router between the two or more PCs (NIC-Hub/Switch/Router-NIC). The is no difference in speed, it’s just a method of communicating. It depends on the hardware, all you need is either a free LPT or com port on each computer and a cable plugged into these ports between each computer.

The simple answer is a crossover cable is used when you are connecting two PCs together directly (NIC to NIC), to connect two computers to each other, you use a crossover cable. When two crossover cables are connected in series, as when going through a patch panel, the result would no longer be a crossover.

Take a good look at the picture above, it shows what I mean. In a straight through cable, both ends are arranged as end A, while in a crossover cable, one end is arranged as end B.

This can also help if you want to make a cable yourself

I’ve seen in another forum that it is better to be connected to the Internet through the ethernet port for usb not, is it true? Anyone can inform me step by step how I connect via Ethernet? Connect the cable to the router port and then do the same with the ethernet connection for my laptop but not connect …. I get an icon on the taskbar indicating that there is connection but at the moment of truth can not open any site, not connected the emule, the messenger is not working …. someone help me?

in theory should look for if you have enabled the port lan communications, that the look in control panel and then network connections, once have connected the RJ45 you have an icon on computers with the blue screen, but test to create a new connection, so you have to your left, you have an assistant.

Follow all the steps that you told me, when done effectively leaving me with a few computers a few blue icons on the taskbar but even so I do not have access to the network

After restoring the essential components, before closing the box back up, Ihooked up my computer and started it to make sure the fans were workingproperly and the storage drives were all in working order. I was able to getto the login screen with no problem, so I put the system back together andturned everything on. The computer booted up, but shut down before it got tothe login screen and would not start back up. I unplugged the Ethernet cablefrom the computer at which time, the computer tried to start itself up withno success. I unplugged it from the electricity for 30 seconds, and triedagain without the Ethernet connected. It started up, and I was able to login. While logged in, I connected the Ethernet cable with success, but when Iswitched on the cable modem, the computer shut down.I then disconnected the power cable from both the modem and the computer for 30 seconds. I removed the Ethernet cable completely and connected the USBcable instead. I switched on my computer and it booted up perfectly, and I was able to log on and surf the net again.

I then contacted my ISP to discuss this problem. The tech had me bring themodem and Ethernet cable to the nearest office the next day to get newequipment. Unfortunately, the computer still shuts down when I connect theEthernet cable and turn on the modem.

While my suspicion is that the on board Ethernet adapter is fried (probablybecause of the dust bunnies), I am hoping someone here might no if it mightjust be a setting I am overlooking. Otherwise, I will just cut my losses andget a new Ethernet card to connect to my computer.

Social security on the web is not a state benefit, but awareness that some of those so-called friends are bad guys waiting for to exploit a weakness in your computer’s defences.

 

Social networking sites – often referred to as Web 2.0 applications – have exploded in popularity in recent years.

 

Some of the most popular, like Bebo, Facebook and MySpace have hundreds of millions of users and are signing up 250,000 or more new accounts daily – and they represent just three of more than 300 similar sites.

 

More and more of these sites are opening for business as well as pleasure, and as with all things in life, where people and money gather, so do fraudsters and con artists.

 

The bad guys have already hit Web 2.0 where it hurts:

 

The German Wikipedia had information pages about the destructive Blaster worm rewritten to include a link to a fix that was in reality malware to infect Windows computers

 

More than a million MySpace users had their computers exploited by spyware when they opened a page hosting an online banner advert

 

Another MySpace user developed a worm that added a million friends to his buddy list overnight

 

Best advice for surfing social network sites is keep your friends close but the rest closed off.
This means taking simple precautions to make your social security tighter:

 

DO add people you know and trust

 

DO NOT click links on pages you can’t verify in case they drop malware – worms, Trojans, viruses and spyware – on your computer.

 

DO install antivirus and spyware protection

DO activate the firewall in your broadband router

DO tell the site’s web master if you suspect a Web 2.0 page is a scam or malicious

Kids and teenagers tend to browse social networking sites a lot – it is where they get news, meet new friends and share pictures or videos among other things that they can do in these sites. However, social networking sites prove to make kids and teens vulnerable as they post personal information for the whole internet world to see, making them easy preys for online predators.

Here are some tips that will help in protecting kids and teens when they browse and use social networking sites:

1.Understand the site – you won’t know what you’re dealing with until you’ve checked it out for yourself. Read the privacy policy, terms of usage and conduct, find out which kinds of people use the site.

2.Review pages – it would be best if you knew what your child or teen is putting on his/her profile page. Try to look at it objectively – meaning, you don’t intrude into their private lives as long as they aren’t doing anything wrong. Although if you see something on their pages that are against your rules, talk to them about it and tell them to remove it.

3.Set internet rules – just as you have house rules, you must be clear about setting some internet rules that the kids must abide with, otherwise, they lose their browsing privileges.

4.Don’t let kids and teens meet anyone they met online – with all the news we hear about online predators and their young victims, I think this point is clear enough and self-explanatory. We don’t want our kids to be the next one to be reported.

5.Private information should remain private – remind your kids and teens not to use their real names, or at the very least, not their full names. They should also know that home addresses, landline numbers, web messenger ids and cellphone numbers must not be publicly seen on their profiles. If possible, they shouldn’t be putting those at all.

6.Look for alternatives – there are a lot of social networking sites today, and some offer a good security measure to avoid anything that we don’t want to happen. Especially to our children. Advice your kids and teens to set the privacy of their profiles, limiting the views only to people they personally know.

7.Be cautious about media – photographs and personal videos must not give away personal details like addresses, schools and car plates. Be sure to check the pictures and videos that your children are uploading.

8.Emotions should be kept in check – kids, teens especially, tend to post highly-emotional entries on their blogs that some social networking sites provide. Advise them not to do this often as they tend to become more vulnerable to online predators. Warn them about the danger they might be in if they keep posting their personal feelings this way.

9.Use web filters – this can help in keeping your kids and teens away from the bad sites, images, videos and other online materials that they should not be exposed to.

10.Removing profile pages – if all else fails, you can contact the webmasters of the social networking sites your children belong to and ask them to delete your child’s profile permanently.

These are just some basic steps on how to protect your kids and teens from the dangers social networking sites may pose. There are other things that a parent can do if they feel that their child really is in danger, but it is always a good idea to apply the necessary precautions to avoid dealing with something bigger and nastier in the future.

Recently I connected my Laptop & my PC via a straight ethernet cable. I used the ip adress 192.168.1.2, subnet mask 255.255.255.0, default gateway 192.168.1.3 for my PC & 192.168.1.3, subnet mask 255.255.255.0, default gateway 192.168.1.2 for my Laptop. At first when I need to backup my data to PC, Both system behaved well connected & I transfered all my data to PC. But after formatting my laptop when I try to transfer data again to my Laptop from my PC, it doesnt work any more. Actually it connects for only some 30 secs- 1 min & at the middle of transfer the conection breaks. It shows the message that it couldnt find the network path. I disabled my Antivirus firewall & my windows firewall both, but still the problem persists. somebody pls help….

Connecting two computer’s without a switch or hub, needs a Cross cable and not a straight cable… Also try to crimp the RJ45 connectors again, seems a bit loose… Also give only IP address and subnet mask, Gateway is not required. Will not do any harm but still… All the best

straight cable work once & I have transfered around 250 GB of data. This time also it connects, but after sometime connection breaks. What may the reason for breaking the connection???

Check the connections proper At the back of the Connecters, it may be Loose,for connecting this Seem to be the Only reason , other than that , i dont think Anything else would be Causing this problem

I already checked the connection…Its well fixed….May it be due to any kind security settings of Windows???? By the way, I also have an Beetel 450BX1 wifi router….can it be any help to transfer my files from one system to another??? My PC connected with it via LAN & Laptop connected with it via WiFi….

You’re using a wifi router, to connect the PC and Laptop so your PC will go with the straight cable, and laptop with wifi. Did you change anu configurations on your PC or Wifi? Check workgroup of your laptop an PC it should be same, Also configure wifi router to give IP Addresses automatically, that it make use of DHCP server. It will avoid configuration settings
