Protect your PC with two-way firewall

The firewall is an important security tool which monitors and filters inbound web traffic and e-mails to prevent hackers from accessing your PC in an unauthorized manner. It acts as a funnel to filter out mails and traffic coming from a malicious sender or website.

To prevent malware and other malicious programs from sending out data from your PC you need to employ a two-way firewall so that the firewall can also monitor outgoing traffic. However, the Windows OS comes with a firewall but it only monitors incoming traffic by default. Therefore, for impeccable protection from malicious web traffic and e-mails, you must employ a two-way firewall.

Reputed antivirus software suites such as Norton Internet Security or McAfee Internet Security provide two-way firewall. But even if they don’t, consider using two-way firewall as a separate program to safeguard your PC.

Keep your Wi-Fi security up-to-date

It is important that you always connect to an encrypted and secure Wi-Fi connection. In case you are not using an encrypted connection or not using passwords while connecting, it is probable that someone would take undue advantage of this vulnerability. Hackers can connect to the same network to intercept your Internet traffic. To prevent this kind of situation or unauthorized access you are recommended to setup a wireless router with wireless security protocols including Wi-Fi Protect Access (WPA) or WPA2.

There is a simple method of checking whether your wireless router is secured or not. Get the list of all available wireless networks in Windows and see how many of them are having a warning indicator next to them. The networks that are not encrypted would show a warning signal whereas the encrypted networks would show you the kind of security they have. If you find your network not secured then refer to the manual that you have received with the router and go through the instructions to turn on the encryption.

  Employ OpenDNS for content filtering

Content filtering is another very effective way of protecting your PC from malicious web traffic and programs. You are recommended to use OpenDNS content filtering to keep malicious agents away from your PC. Apart from adult content, the OpenDNS can also block malicious content coming from websites that spread viruses.

Ensure using PIN protection for mobile devices

The trend of using smartphones and tablets is rising.  Today many of us use mobile devices such as mini computers which is also used for e-mailing as well as storing important files, photos and videos. When these devices get stolen or lost there remains a huge probability that the stored stuff would be misused once the device reaches wrong hands. The best way of preventing such kind of situation is to enable the smartphone or tablet with lock screen protection. Once enabled, the device would require a PIN or password every time the user wants to use it.

There may be different ways to enable PIN or password protection on various devices but it is provided with every smartphone and tablet. You just need to explore the features and understand how to do it. Once you start using the screen lock feature, you become partially relieved from the worry of data misuse in case of loss and theft.
