The Internet has now a very important tool in everyday life. Several decades ago, people have a come though the Internet an excellent way of connecting systems. Now it is this very same thing that puts networks and systems into danger. With its ever increasing popularity, people are now faced with more challenges in Internet security, like identity theft. In the wee days of the Internet, networks were most self-contained and securing them, are not a difficult task. As time passed, Internet users became more mature and experienced; the Internet also has become more complex. Simple devices and single-layer security are now inapplicable.

Being anonymous when browsing is a way. Challenges of Internet security can be tackled by considering the foundation of information security. This includes discretion, reliability and accessibility. Discretion refers to making sure that sensitive data is safe. Such information ranges form personal identifiable information to keystrokes. Many companies and organization depend on the Internet for communication. The big challenge is keeping their network systems form being hacked and exposed. Serious threats can come in the form of leakage of information to deletion of an entire database.

Last of the foundations is the availability of information. The Internet is largely dependent on the accessibility of data. Without this, no transaction, business and functions can be done. A major challenge associated with information ability is denial of service attacks from hackers. This attack has the ability to flood a system with unsolicited traffic such that no one will be able to access it. Online systems must be properly tested as slight misconfigurations can lead to such attacks.

These three aspects of information are essentially what are at stake. Internet security may encompass one or all of these aspects. The ever changing threats to these foundations are the ultimate challenge in the aspect of security. This challenge entails the realization of security to achieve and preserve these aspects of information.

The various challenges of Internet security can essentially be overcame by considering a wide range of security approaches. These approaches include services that can regulate user access to a system, blocking of applications, prevention technologies, and many others. It is also important that whatever approach is implemented, it should also be properly managed and maintained. Many tools are now available to overcome such security issues. These include anti-virus software, firewalls, intrusion detection and prevention, network infrastructures, access control, secure WLANS and data encryption.

Antivirus software is utilized to counter malwares. On the other hand, firewalls can monitor traffic and alert a user of an unauthorized program. Intrusion and prevention tools protect a system from post scans and DoS. The proper use of switches, routers, also help in establishing secure connectivity, identification services and network management. Data encryption is what the most essential. The protection of data is the very essence of security. Anything unsecured paves a way for thieves to steal very important data.

Challenges in security are forever changing. Just as how people have come with the Internet, they will also come up with solutions as to how these challenges can be confronted and solved. With the proper approach and techniques, any challenge that will come in the future will be eventually solved.

When configuring a wireless security in your network to protect your computer, try to change the default SSID of your routers and access points. SSID is the network name provided by the manufacturer and this is usually the same. Even though knowing the SSID does not allow hackers to hack into your system, configuring your own SSID makes your network less prone to interception. Disabling SSID broadcast is a step in line with enhancing security. SSID broadcast is a feature commonly used in businesses but in home networks, it is not really needed.

Avoid connecting to open Wi-Fi networks because it raises security risks on your computer network. Most computers now have a setting which automatically enables connection without the need of notification to the user. Try to check this and disable it if it’s present in the setting. The positions of access points or routers also play a part in wireless computer security. Wireless signals often reach outside the house to the streets and these can be detected. Try to place the router or access point in closed area that is far from windows and open spaces. An ideal location would be the center of the house. This does not really prevent wireless signals from going out but leakage is definitely minimized. As earlier mentioned, total “network privacy” isn’t possible yet but you can get a better shot at it by having a wireless computer security.
