Securing your Windows Machines

Paul

After a Long day at work, you sometimes feel like there isn’t much you want to talk about. Then this idea comes to me? Why do people blog and why do people talk about security?

I’ve come to realize something, I’m not one who was grew up understanding bits from bytes. I grew up as any family does fighting with my siblings.

Having been blogging the past few years, it seems like only yesterday that I started blogging. Cliche I know but still very much true. Most blogs do what they know, I aim to learn and teach each day I blog. Like days like this when the world is pretty much quite and the [intlink id=”3214″ type=”post”]remnants of the conficker[/intlink] worm dies to a rumble.

[ad#cricket-right-ez]So how do you secure your Windows Machine?

After a day long battle with  my wife’s system, I grow to wonder if there is something I should do differently with how to prevent Viruses and Worms on her system.  So I’ve groomed my Knowledge base and come up with 5 good points when it comes to locking down your Windows Machines:

  • [intlink id=”994″ type=”post”]Lock down your Router/Modem[/intlink]  — Some people don’t know that having an insecure router with weak passwords is a way to get on another system.   This can easily be prevented if the users takes some steps to prevent. it.  Although if a hacker wants to break your encryption and find your Signal there is really nothing you can do but try to prevent that.

  • [intlink id=”2205″ type=”page”]Firewall and Anti-virus[/intlink] —  Although I know people think I am a broken record this will always be something I encourage for everyone who reads my blogs.  I will never stop beating people over the head with this.   Seeing the [intlink id=”3272″ type=”post”]Conficker map[/intlink] tells me there are quite a few without an Anti-virus or a Firewall, which might of given someone a heads up find out if they do or not!!

  • [intlink id=”2984″ type=”post”]Disabling AutoRun[/intlink] —  This can prevent a USB stick from installing software it shouldn’t.  Remember Microsoft has issued an statement on how to disable it for sure.  Although I must say The Security Now episode 187 seems to talk about this really well and how to make sure you do disable it the right way.

  • Make sure it is a Limited user account —  Most people always run as administrator when in fact that sometimes makes you more vulnerable to viruses, worms, and trojans.   Any software you install as an administrator will automatically be given Administrator rights.  That can be very bad when it comes to virus and such.

  • [intlink id=”2883″ type=”post”]Keep your System up to date[/intlink] — This is essental for people who to prevent exploits to be used against you.  Although  if your like me and you want to make sure your software is up to date some of that can be done with [intlink id=”553″ type=”post”]APPSNAP[/intlink].

With These tips, your system can be a little more safer.  Just remember there is no perfect way to protect your systems 100% only some of the time.  The rest depends on you, because your the last layer of defense.  Also it isn’t a bad idea to [intlink id=”2407″ type=”post”]back up your system from time to time[/intlink].

Signs of a Computer Infection!

Paul

So I was thinking this morning what I missed and I totally missed on how you might be able to tell if you have a computer virus. It does me no good to talk about a virus if you don’t know you’re infected. I was thinking of the times I had a client who had trouble but wasn’t what I thought.

So How do you know?

Some people would say it depends on factors but here are what I call clues that make me suspect a virus:[ad#ad2-right]

  1. Slow or Sluggish computers —  Here is what I know if the computer is really slowing down and have a dual core or quad core.  If you are running a system and sees a lot of hard drive activity even when the computer is idle then it might be a virus or it could be a program doing what it is supposed to be doing.  So this is somewhat of an indication but not always.

  2. Slow internet connection on the computer or on the network — Due to the fact that most people have a router that is connected to all the computers and if you internet connection on all your systems are slower than normal then you could have a virus.  I use Speed Test website to help determine this.

  3. Corrupt files or Missing files —  Sometimes you have a text documents or files that are missing and you have to pay to get them back.   It’s an old scheme and usually once your files have been encrypted you can’t get them unencrypted.  So this is why I added this one also because it varies from virus to virus.

  4. Programs don’t work like they used to —  This is also a very common association with a virus because virus makers don’t have time to test it out on a variety.   Most of the time if you get a call that a program is no longer working tat would be the first thing I’d look at, if not check to see what other programs have been installed lately.

  5. In some cases more files are the Hard drive —  This can be a indication of a virus because the virus might be using the system to host files or other such illegal activity.   Although this is happening less and less it can still be a possibility and should be checked out.   I like to use a graphical tree size program to determine if that is the truth.

  6. Pop ups or Browser redirects — this is a common thing along the way.  It’s always the same and saying something like “you have a virus” or “You unprotected and you might have a virus”.  The theme here is to scare the user into buying there product that does not do anything.   It sometimes even looks like a real anti-virus program or spyware program but in truth it is just a scam.  In some cases it will send you to a site because it keeps wanting you to buy the product.

  7. DNS Changes on you — Some hackers like to have you go through there server so they can watch everything you do online.  They are wanting to get the sensitive information of bank account, and other important accounts.  This is really the ones that need to get off your system asap.

[ad#ad2-left]These are the signs I’ve seen in the past that would indicate a virus but as with any problem.  You will need to check for all the possibilities.   It is always going to be an issue with people because most people don’t know about the signs, now you do and you can now be a better computer user.  It is you who can only fight viruses by knowing all the possible system and only you can defeat a virus.  In the next article I will talk about the tools to help you find and defeat a virus.   This will be a big blog post because I have so much to teach and explain.   If you like these post by all means leave a comment and help spread the word.

Reports are coming in that WPA is no longer secure!

Paul

[ad#ad2-left-1]

According to a media reports, Erik Tews and Martin Beck claim that they have found a way to unlock the Temporal Key Integrity Protocol (TKIP) key, used by WPA, to read data sent from a wireless router to laptop computers. According to the researchers, the key can be cracked in 12-15 minutes.

According to Sophos, they are claim that people can now watch what you are doing on a Wireless router to a laptop. Although this isn’t to be unexpected this is a very serious out come. It is now easier to watch what people are doing online. So does that mean people can see everything you do? Not necessary. According to some people this is harder than it seems, most of the websites you visit are not encrypted, but websites that use the “https” protocol are more safer to use online. You should be safe if you are buying things online as long as you are sure it is secure. Some other steps to take to help make it harder to unencrypte your wireless single is to use Roboform promotion codes you will get for 10% or 20% off the purchase price!!

[ad#ad2-right]Some other steps to consider are:


If you have a wireless router and want to be secure with any transactions online you might think about hooking up to the internet via the CAT5 cable.  This is one way to prevent anyone from seeing what you are doing online and protects your privacy.  Although this too can be overcome in certain circumstances they are much harder to do and implement so you are safer this way than with most others.

AT&T smacks the gauntlet at you!

Paul

[ad#ad2-right]

According to Cnet News:
The test, which began being applied in the Reno, Nev., area on Saturday, limits customers of AT&T’s slowest DSL service to 20 gigabytes of monthly data transfers, while users of the fastest service will be limited to 150 gigabytes. Customers will have access to an online tool to track their usage and will receive notification when they reach 80 percent. Those who exceed their limits will be charged $1 per gigabyte.

[Via Cnet News]


So you just received the information that AT&T is doing this. How do you want to keep track of your online usage. I’ve got some good tools to help you. Although they will only help to a certain point you must remember a few tips and these tips are:[ad#ad2-left]

With these steps you would greatly increase stoping unnecessary use of your bandwidth.  Most people don’t understand that any program you use on your network will be counted on the total bill.  If you know of any good ways to help stop bandwidth by all means tell people and if you find any good programs that might help, please leave a comment.

Limiting Use of Your Bandwidth!!

Paul

With the Recent Comcast deciding to declare how much of bandwidth you can use.  I decided to talk about how to limit your bandwidth.  So Here are some tips and tricks to get the most out of your bandwidth:

[ad]

Chapter 1 — Understanding your Wireless Router : This is a must.  This chapter talks about how to access your router and and how what is an IP!!

Chapter 2 — 10 Ways to keep your wireless router Secure — This one will help with those pesky neighbors who are leeching of your internet and Bandwidth!

Chapter 3

  • Turn off Auto Update to Unimportant programs : Having several programs checking for updates can start to add up.  Although this is a small amount of bandwidth.  It will give your that extra amount.

  • When not using your Internet turn off your Modem : This one is the most useful because when your not using your internet just turning off the modem will prevent you from using to much bandwidth.

  • Use a program like AppSnap to update your programs : Having told you that you should stop auto-updating on some of programs.  Here is how you can update manually.  This little program will check most of what you have installed on your system and will let you know which ones have available updates.  This should be done once a week or every other week!!

  • Use a Program like GoodSync to perform backups : Know that some people have backups in the cloud this will greatly reduce the amount of bandwidth your system will use to upload to the cloud.  Get an E3 Amazon account and use the program to back to E3.

  • By an External Backup Hard Drive : This option is also good for people who have the need for all the bandwidth possible.  Buying an external hard drive for use as backup is also a good idea so that way you don’t depend on your internet bandwidth.   Just remember when you do a backup take it off site just in case of a fire or earthquake or something like that.   Might be time to buy a Safety Deposit Box, and use that.

In an Upcoming post I will be discussing the program or tools you need to  monitor your bandwidth!  This is going to be a must for thos who need to monitor you monthly bandwidth per month.  I will be looking into some of the options available to you for free.
