Why is it important to secure your network?

Before starting i would like to share one of my personal experience with one of my client.

I got a call in late evening and my client was almost lasted all his hope. According to him, one of his competitor actually managed to access his network and successfully stolen all of his confidential data stored on that server. Not only this he also deleted all the files from the network so that my client should rework on everything. This was bad on his part, but that late evening made him realize that why so much of security awareness is happening these days.

However, after doing so much of hard work and forensics we found the traces to reach the intruder and finally we were up with our side of job, one of the company employee was involved in that activity. But during this course of event this client really had a hard time and faced huge losses. But there is always a say โ€œEvery next day is a new morningโ€œ.

What i want to explain is the fact that just hardening the operating system or securing the network infrastructure doesnโ€™t makes you complete secure. Also, it is just not about the bug-free code, a good network security rests on the ability and ethics of people who run your networks and on the people who are having access to it.

But unwillingly we know that all humans canโ€™t be priests, and everyone out there ainโ€™t having same beliefs as we do. However, we just donโ€™t need to insist everyone to take our role of job. What we need is a trust worthy team to develop solutions that can help us overriding the captioned matter.

Corporate security is one of the major concerns these days.

There are multiple systems like application servers, web servers and database servers with holy lot firewalls, routers and intrusion detection systems to configure and maintain. So many people access these networks, starting from telecommuters, remote systems to corporate business partners.

As these dataโ€™s are very confidential and are very important for the business sustainability any breach could incur millions and billions of dollar loss for the company. The dataโ€™s are multiplying constantly and are widespread all across different systems which makes it very hard to manage and secure properly. Dataโ€™s are scattered within different paradigm ragging through personal computers, servers, mobile systems, mobiles, PDAs, flash drives and storage devices.

In such kind of situation taking network security lightly would result to a great mess. There are lot many illegal stuffs available like, password cracking tools, virus programs, sniffing tools and others. Which help unethical people to do illegal activities to gain personal benefits or maybe to ruin the corporate identity. In such scenario appropriate measures are really a great topic of concern.
