Comodo assert that their firewall is unique, distinctive, matchless and rare in that it passes all known leak tests to ensure the integrity of data entering and exiting your system. Comodo has put firewall through all kinds of stylish tests to ensure its firewall powerful enough to ward off these attacks with default settings. No other firewall has had to work this hard.

• Change the default administrator usernames and passwords. Router manufacturers set a default username and password as an access protection. However, these sets of default username and passwords are of simple logins vulnerable to Internet hackers. To ensure utmost login secrecy, change the default immediately.
• Activate compatible WPA and/or WEP Encryption. All wireless fidelity equipment have support for a form of encryption. Encryption is a technology that makes messages unreadable by humans when you sent it over a network, may it be LAN or wireless. Of course, you’d want to have the strongest encryption that is available for you to use with the wireless network you have.

• Change default SSID. SSID is a network that is used by all routers and access points. As for the logins, manufacturers also set default SSID for their products. Important point to notice is that when a network is using a default SSID, it is consider right away being a network configured poorly. Internet hackers are more likely to attack these networks.
• Deactivate SSID Broadcast. A router or an access point typically broadcasts SSID (network name) over at regular time intervals. Since SSID Broadcast feature was designed to cater roaming Wi-Fi clients (i.e mobile hotspots), there is not a necessity to enable this feature in a home network.

Let us admit it: many wireless home connections have network security systems that are inappropriately secured. This is quite understandable because not all are well informed with the risks of either unsecured network system or the time to take setting up a decent security system. Because of unintelligent set up of wireless network, different risks and security problems arise. The Wi-Fi or Wireless Fidelity networking products of today’s time actually add up to the problem because configuration of its security features consumes and never intuitive.
To help you people who are not so into technical things, we are posting some tips that you can use to improve the quality of security of your wireless network at home. Watch out for next post containing the tips.

To check if your computer has been turned to a zombie, there are available test sites you can find on the net. But you don’t just trust any site, you have to be somewhat picky on the test site that you will choose. Take this general rule: do not rely completely on sites that are provided by some company that is offering you firewall software products because obviously the findings will be bias: they would tell you to purchase their product because that is what they wanted from you.

After installing a reliable and trusted personal firewall, make sure that it is configured correctly. Then test it to ensure that the application is working purposely.

• Make sure that you are keeping your personal computer patched. This will help your home network fight against different known vulnerabilities that can damage or weakened you security system. Like viruses, Trojans and worms, vulnerabilities are discovered as often. New vulnerabilities are usually the effect of coming up of new malicious files and software. Most of the time, these vulnerabilities can be found in operating systems, in different web browsers and third party software. If these vulnerabilities will be left unpatched, hackers can easily exploit your personal computer resulting in unauthorized control and access of information from your computer.

• Never open suspicious electronic mails that came from unknown senders. A lot of worms and viruses use the ‘social engineering’ mode of operation to carry out its malicious intents. By this, it means that worms and viruses fool the user to join different processes that will lead to system infiltration of the culprit and thus making the user another one victim.

  You can easily identify this. Usually, electronic mails from senders who you do not know or have no idea about are the carriers of the worms and viruses. You should just delete spam messages. If ever you opened one and it has an attachment, do not open the attachment.

Firewalls are basically customizable which means that you can either add or remove filters based on your existing conditions. Here are some terms that you need to be familiar with when dealing with firewalls:
• IP (Internet Protocol) addresses – unique address assigned to a network machine, usually in the format 255.255.255.255
• Domain names – there are the human readable equivalent of the IP addresses, each IP address corresponds to a certain domain name
• Protocols – this are the communication services that are used in a network or Internet connection which includes IP, TCP, HTTP, FTP, UDP, ICMP, SMTP, SNMP and Telnet
• Ports – numbered ports serve as the entry point for different services running on the network or the Internet
• Specific phrases and words – this allows the firewall application to look for specific catch words or phrases to block

A perfect personal firewall is characterized as inexpensive and easy to install and use with clearly defined configuration options and the ability to hide all ports that will make your computer system invisible from PC scans. Another important characteristic is that is alerts you of serious attacks and ensure that there are no unauthorized entries to your computer system.

Microsoft Windows firewall is usually the choice because it is bundled with the Microsoft Windows Operating System (Vista and XP Service Pack 2 editions) and is usually turned on by default in order to block incoming threats from the Internet. Until you have a decent third party firewall replacement, this built-in feature in Windows should be left turned on.

The firewall is your network or computer’s first line of defense against external attacks which are meant to gain access to critical information. In order to be truly effective, system administrators and computer owners can implement various types of firewall techniques to fortify their defenses against malicious attacks. Common types of firewall techniques are:
1.Packet Filter- inspects every packet that enters or leaves your network applying rules defined by the user
2.Circuit-Level Gateway – security mechanism applied to UDP or TCP connections
3.Application Gateway – application specific security mechanism like Telnet and FTP servers
4.Proxy Server – hides the real network address by intercepting incoming and outgoing messages that flow through the network
