IT security means securing important information of an individual or a company from unauthorized access so that confidentiality & integrity is maintained. Most of the companies & financial institutions assemble confidential information about their employees, customers, products, research documents, financial data etc. This data is stored on electronic gadgets, computers and transmitted across networks to other computers. One of the biggest concerns in the corporate world is the security of its data, which is constantly being targeted by the cyber criminals trying their best to steal important information like usernames and passwords, credit card details / corrupt the data, solely with the motive to either misuse the data or use other people’s account information and perform illegal activities on the internet, or to harass the system administrators and boost self ego by pointing out the loopholes in their security measures.
In other words we can say that any application or network is vulnerable to attack by the black hat hackers causing harm to individual computer, entire network system, or the server. Most of the system administrators tend to ignore the issue thinking that it will never happen to them. But this something one can be sure about.
We are always concerned about securing our homes with the best locks available in the market, but get least concerned when it comes to safety of our online profile, computer, network system. The cyber criminals can not only steal data from our system, but can also hamper our online identity by misusing the information they gather / finish our online existence by deleting our account. Their intention is not always to steal data, but also to develop the fear in our minds that out identity is never safe if we get into any kind of hassles with them knowingly or unknowingly.
The fear is not always from outsiders to harm us, but from insiders as well who can while sitting in our office / home can take away important data to be given / sold to our competitors. This way our crucial information is exposed to the world and we eventually lose our business to our competitors.
The websites of corporate houses, top global companies and government institutions are always under threat because they can be easily penetrated and hacked by any smart hacker, if the security patches are not in place. Many of the advantages of web applications like online shopping, internet banking meant for giving convenience to the users also makes them incredibly insecure. Most of the applications these days are built with a web interface, but unfortunately the web development work is not done with security in mind. The developers and designers are more focussed on the convenience aspect and also the ease of use. Thus, adequate measures need to be taken which can be implemented by a professional or a team of professionals who has knowledge on the subject, know the ways by which the system can be attacked and then protect the system by installing patches.
We at AVS act as security consultants & give you guidelines & implement security at your work place. We also do web penetration testing, usually called pentesting, which is evaluating the security of a computer system or network by simulating an attack from a malicious intruder. As most of the business process has moved to the web, full time pentesters are required to keep the confidential data safe. AVS is also engaged in security audit / security service which helps in finding holes in the network system and also suggesting remedies to patch the vulnerabilities.
