The Importance Of Protecting Your Customer’s Information

By

protecting online info

Whether you deal with selling items or services online or in a store, there are risks when it comes to your customer’s personal information. Even the POS cash register systems that many retail chains use are subject to hackers since they work over the internet, and without the proper protection these hackers can walk away with more than just people’s credit card numbers.

As you can see, there are many levels at which a business needs to work to protect their customers and their information. So, how do you do it? [Read more…]

Of Unsecured WiFi

By

wifiI didn’t realize that there are still a lot of people who do not really pay attention to securing their WiFi at home. I guess that I have always taken it for granted that once you set up any connection for home use, you install passwords and other measures to protect it. Apparently, in this day and age, not everyone has the same idea.

My colleague was telling me, just last week, that his connection at home seems to be running exceptionally slowly. First thing I asked him: are you using a wireless router? When he said yes, I asked him about a password. Just as I guessed, he said “What password?”

I moved to a new building a month or so ago and have been having problems having wired Internet hooked up. I have a mobile dongle which I can use to a certain extent but guess what? One day, I turned my WiFi on and voila, the laptop automatically connected to some fella’s wireless connection.

The fact is that this is such a common thing. Hotels, shops, and other establishments are also guilty of this neglect. I have a friend who works from home and is entirely dependent on the Internet. When her connection goes down, she simply gets in her car and drives to a nearby hotel where she can mooch.

It may seem funny or amusing, but if an unscrupulous individual gets wind of your unsecured WiFi, you just might get your bum bitten. If I were you, I’d make sure my WiFi is secure. How to do this? Let’s look at this in the next post.

Overlooking Mobile Phone Security

By

phonesThe average person spends a lot of time and money on making sure that his personal laptop or desktop computer is secure. From firewalls to anti-virus software to spyware removers – all these kinds of software are installed onto computers to make sure that any kind of malware is kept out. But do you pay as much attention to security on your mobile phone?

According to a recent survey conducted in the UK, mobile phone users do not really pay that much attention to security. IT Pro has this story:

Results from a survey of UK mobile phone users has found too many of us are playing fast and loose with sensitive data stored on our mobile phones.

More alarmingly though, it also found that the majority (99 per cent) of those questioned also used their mobiles for business use, creating a potentially weak security link to their employers’ corporate systems.

So what kind of sensitive data is stored in mobile phones? I think that you can answer this yourself but let’s take a look at some of them:

• Bank account details
• PINs
• Passwords
• Social security numbers

More than these things, mobile phone users also admitted to accessing and storing business data on their phones. This includes downloading spreadsheets and other business documents.

The worst part is that despite the fact that this information is stored in mobile phones, the units themselves do not have passwords and other forms of security measures.

The bottom line? At the very least, we have to put passwords on our mobile phones. Even better, enable encryption.

How To Secure Your WiFi

By

wifiSo you’re convinced that you have to secure your WiFi. Good, now we can make some progress. In the previous post, I mentioned using a password. This is the first step is making sure that unauthorized users will not be able to connect easily.

In most cases, people use WEP, or Wired Equivalent Privacy. While this provides a certain level of protection, WEP is relatively easier to crack. If a hacker is persistent enough, WEP will give way quite easily. As such, I suggest using WPA (Wireless Protected Access) or WPA2 instead. Either way, you will need to indicate an encryption key. As with other instances wherein you have to choose a password, choose one that is hard to guess. Long encryption keys that are combinations of letters and numbers are the best kind.

Another thing that you should do is to change the default SSID (Service Set Identifier) name. This is what computers used to detect available wireless networks. Most laptops and mobile phones are set to automatically detect available SSIDs. If you change the default name, and turn of SSID broadcasting, users who want to connect will have to enter the name manually.

Last, you might want to disable DHCP, or Dynamic Host Configuration Protocol. This will require you to assign IP addresses manually. If you can do this, then you will have added security. However, if you think it’s too complicated, you can leave it. The first two tips above will already give you good enough security for everyday purposes.

How Secure is your Wireless Network

By

Wireless networks which are normally evident in homes right now does provide a lot of comfort as far as Internet options that we see common these days. The same is likewise present in companies, doing away with the standard cable infrastructure and making it easier to clean up your homes without having to worry about tripping on any cable for that matter.

But while such a privilege is another fruit of technology, duty calls as far as limiting network access. Passwords are still the wise investment for securing your wireless network and at the start it does look like a lot of work and a bit complicated. Limiting access by providing a (Media Access Control) MAC address and disabling the SSID broadcast can help in making sure your wireless network cannot be found or detected.

With various technology means today, practically anyone is trying to look for wireless internet. That is how much Internet is being demanded these days. But this includes both sane and malicious people who may want to give problems.

So for people who want to protect their wireless networks, here are some tips you can consider:

  • Don’t use defaults. It is almost always a good idea to change default usernames and passwords and your wireless router is no exception. One of the first things you should do when setting up your wireless network is to change the default administrator username and password.

    Additionally, most routers have a default name, or SSID, for your wireless network (i.e. belkin54g). It’s a good idea to change this for several reasons. First, if you don’t change it, it will serve as a hint to intruders that you probably left the defaults in place everywhere. Second, once an intruder knows what model router you’re using, it’s not difficult to find the default username/password and to look for known exploits.

  • Use encryption. Every good router supports encryption and if you’re not using it, your network’s security is likely to be compromised. If you have newer equipment, use WPA or WPA2 encryption. WEP encryption is less secure.
  • Use MAC address filtering. Every network card, whether it’s wireless or wired, has a unique Media Access Control address (MAC address). A good wireless router will allow you to specify that only certain MAC addresses be allowed to access the wireless network. This can help prevent unauthorized computers from accessing your network.

    Be sure to read your router’s documentation to find out how to set up MAC address filtering. To find out how to determine the MAC address of your network cards, click here.

  • Use your firewall. Most good routers have some sort of firewall built in and it should be used in addition to a good software firewall that is installed on the devices accessing your wireless network.
  • Disable SSID broadcast. By default, most routers “broadcast” their existence to the world. This makes it easier for devices to detect their presence and connect automatically. But this broadcast also gives intruders a target. By making your network “invisible” and setting up devices that need to access it to connect manually when in range, you can make your network less of a target to less-savvy intruders.
