Network Security Policy is a concept which defines controlling, managing and controlling your network. A network can be group of some computers or server or even bigger than that. It can be inside your office premises or on the web. For every thing it is today considered to keep a watch. Protection is important part which we ignore mostly or just reply on 3rd party devices. Basically we are satisfied with ready to use services that are received with the existing software or hardware. But do we really know how all those stuff work. No not at all. Today computers are not just a part of desktop system of lan, but it is can be a door to data centers. Taking the advantage of vulnerabilities attackers penetrate and cause losses. In such cases you must understand and deploy a strict network policy for your network. Network Policy is a kind of outline of your network access which shows how the architecture of your network works. How the security environment works and how it can protect you and your network. It is a written document which is safeguarded and used over time to time and upgraded.
You can also adopt any ready to use security policy if you do not want to invest your time and money in creating your own. But for Enterprises they prefer to begin from scratch. Security policy helps you to keep your users protected and also keep the unethical guys away. The first step to begin working this is to understand and learn how to make a security policy, what can be damages if you do not deploy and how much protection is provided under this. To write a security document needs a better skill to understand the network architecture. As the technology keeps on changing and it become more advance, the threats are also increasing. We just cannot stay unaware about this. Because a simple mistake can create big losses. Computer security threats are not uncommon.
They are too increasing day by day. There are many threats in the from of virus, worms, which are not hidden and they are free on web. They can enter your system in the form of attachment or updates without your knowledge. Recently many systems were infected with malware due to Activex updates. This was later on fixed. This is web based threats. Let’s talk about inner threats. Usage of removable media, infected systems, pirated software, etc is the most common issue. Every enterprise needs to connect to web and expand its business opportunities in a cleaner way. A security framework defines certain rules which are also called as policies. Everyone has to follow the same and many risk are avoided under this. Right now you might be on a network which is accessed worldwide. Are you enough sure that this is too safe to us. There are different kinds of vulnerabilities which cannot be detected easily. There are many malicious tools used by people and unsecured systems are easy target.
Many of us are thinking that does there is a need for security policy if my system is secured behind a power hardware and a team to manage. In my views yes. A network security policy defines the usage of network in a enterprise and how to respond on attacks. It is a kind of foundation for your IT section which is also an asset. You cannot just rely on the network admin to take care of stuff. Once the polices are defined everyone tends to work under those only. Before establishing a network policy it is recommended that you study the risk involved. To protect against hackers you must know the possibilities of attacks and appropriate solutions to defend them. There are many things which are counted under security policies. Some of them are:
- Finding the material to be protected. They are hardware, software, data, people, etc.
- Finding the possible attacks from hackers. This can be done through various programs like virus, Trojan, worm, etc.
- Finding causes of corrupt data which can occur on the lan over network.
- Finding the location of infected system and method how to deal with the same.
