MWQ133 asked:


I have a Linksys router and my laptop has Vista Home Premium.

Do I change the network security key (I know the old one) through Vista’s Network and Sharing Center, or through the router itself…or both?

Thanks in advance.
Brad, thanks, yes I’m using WPA encryption. So, the router is the boss, in essence?

With many individuals and businesses connecting to the internet using wireless devices, and the reported cases of security breach and identity theft, having an awareness of wireless security measures to improve system security is a must. Many wireless users simply do not know that they are open and exposed to system *********** and bandwidth theft. Here are several suggestions to prevent your system from becoming a wireless hotspot.

(i) Change the password on your router. All routers come with preset service identifiers. Hackers are familiar with these protocols. You should change the password to something that is difficult to guess. Do not change the passwords to something as simple as myrouter which is easy to guess. You can rotate passwords frequently as an extra precaution.

(ii) Enable encryption. You should follow the encryption procedures provided by your routing device. WEP and WPA2 are the two preferred encryption measures with WPA2 the preferred and most up to date option. This technology encrypts traffic and scrambles it so that unauthorized third parties can’t make use of it throwing a spanner in the works for packet sniffers looking to procure sensitive details.

(iii) Keep a close check on remote access points. For companies that run web interfaces or remote system access points, security protocols should be established. Password access should be changed frequently.

(iv) Avoid using unsecured wireless hotspots in public locations. Malicious third parties frequently setup traps that are designed to route traffic through setups that are used to screen traffic with the intention of securing sensitive details.

(v) Always scrub all hardware that is sold or disposed of. This eliminates the chance that a third party can discover sensitive data or passwords that can be used for identity theft, financial crime or to gain access to corporate systems.

(vi) Use wireless security software. Whether you’re an individual or a corporation, this software has many benefits. A program such as Mcafee wireless home network security uses automatic security key rotation every three hours for encryption purposes. The software also secures your router and provides event logging and alert monitoring to scrutinize for terminals attempting to gain access. Institutions should consider more advanced software such a Manage Engine Wifi Manager.

Taking the time to plan and implement security measures prior to wireless use is the best way to protect yourself. A little extra time during setup is time well worth spent.

Orly? asked:


I’d really like to get into network security, computer forensics and such. I have a light background in IT. I’m wondering what skill you need? Do you have to know how to code? Or is it more, that you have to know how things work?
I have 4 years of college

College doesn’t really show you HOW to do thing. It just helps you learn concepts, and terminology.

The demand for network security experts has been pretty heavy lately, and it’s going to get heavier.

Dan asked:


According to a 2007 study by the Ponemon Institute and Redemtech, 70% of data breaches result from the loss of “off-network” equipment. That is, equipment that’s not connected to the Internet. There are some other staggering numbers, but the point is that a huge percentage of data breaches are NOT “hackers” breaking into networks. They’re good old laptop thefts, basically. So which is more important to focus energies on (not that any aspect should be completely neglected): laptop security or network security?

Network security should encompass all aspects of a network from the desktop to the perimeter. A multifaceted and multilayered approach to network security for any organization or business provides the ideal protection coverage against internal and external threats. For small networks or even a single computer, a router with integrated firewall is usually sufficient. For larger networks a dedicated firewall at the network perimeter may be more appropriate. A good number of dedicated firewall appliances can also provide secure Virtual Private Network (VPN) connectivity. The most common feature provided by dedicated firewalls is their ability to inspect, block and report malicious network activity usually initiated from the internet. Firewalls that provide this functionality are often designated as an Intrusion Prevention System (IPS).

A content filtering device is a good complement to a dedicated firewall. These types of devices usually include the ability to monitor, filter, regulate and report on all web related traffic. They are usually installed transparently in line between an internal switch and router or firewall. All internet inbound and outbound traffic is then forced to pass through it. This type of installation is often referred to as “bridged mode.” Some content filtering devices can also be integrated with a network directory for individual, detailed monitoring of end user web related traffic. Microsoft Active Directory and Novell eDirectory are examples of directory services that can integrate with a good number of content filtering devices.

Desktops and servers should be protected by antivirus and anti spyware applications. There is a wide variety of enterprise level threat protection software available in today’s current marketplace from numerous vendors. The ideal threat protection software should include at a minimum, frequent if not daily virus definition updates, centralized management and reporting, active protection and the ability to guard against unknown threats.

Another aspect of the network that needs security related consideration is what the users are allowed to do on desktops and laptops. Management may want to evaluate and implement access and rights appropriate for their environment and the nature of the organization. Should users be allowed to install software on their own or should the use of removable devices be disabled company wide are examples of issues that should be addressed when defining security policies and procedures.

Lastly, physical security is also important when considering all security related aspects of the network. Servers should be secured and access regulated and documented. It is also best to make sure that backup media is secured whether stored on-site or off-site. In conclusion, a proactive effort in utilizing these network security best practices coupled with consistent monitoring, constant re-assessments and adaptive reconfiguration are all essential in ensuring the safety and protection of an organizations data, intellectual properties and physical assets.
