For the smooth functioning of a company, computer networks and internet connectivity is a must. But with these requirements, is associated the risk of getting hacked or inviting virus from different sources. The ability to provide a secured system of protection from unauthorized entry, relives the companies of huge mind racking troubles.

Reams and reams of pages of information and innumerable data are located in the computer systems and servers of some companies. Not only are these important for the day to day functioning of the organization, but also they have a bearing on the working of many people. Such data protection is mandatory for the organizations and for this, they will have to entrust their system in the hands of a competent information security audit agency.

By doing a detailed audit of the security system in the network, the agency comes to know about the loopholes that might be present. In a computer network, there are a number of points of entry because there are a number of computers and these are being used by people for different works. Moreover, the link is also present to the servers. Despite of sufficient antivirus, or malware protections, it is possible to breach the information security cordon.

When the audit is done, the experts in the agency work with the method of penetration testing. In such a method, these experts use their know how to first try and enter into the given network by ethical hacking measures. Any network is penetrable and this is what these experts believe in and they try to find as many possible entry points as they can find. With the penetrability tests, the agency comes to know about the possible modifications and the points at which these modifications are required.

Most of the companies dealing in information security are nowadays adopting these measures so that the baseline assessment of the security of the computer network is done from the outside. The penetration test is a simulation of the hostile network attacks which are done in a covert manner by possible hackers or virus makers. By means of such tests, the information security personnel are able to know about the points of vulnerabilities and potential entryways into sensitive data in the given IT infrastructure security system.

The information security audit is done by means of port scanning, vulnerability identification of operating system, web application, antivirus, and other components of the networks. Then the audit is analyzed and reports of penetration testing are put under scrutiny. This helps in charting out an organized network security system. The expenditure, blue print of security programming, and operational procedures of the future securities are laid down for the benefit of the client companies.

By means of the information security audit, companies will be able to lay bare their existing system. This will also lead them to rethink their information security strategy and give them an opportunity to upgrade it or renew it. Without the proper assessment of the security system, it is not possible to know if it is weak or is providing adequate protection. With advanced means of data theft being rampant in the IT world, the line differentiating the risk and protection is quite thin. With proper information security audit and its correctional measures, it can be a boon for any company depending on computer networks.
