Vulnerability Assessments are Critical to Network Security

If your business is not taking a proactive approach to network security,with regular vulnerability assessments, your network could be vulnerable to an increasing number of malicious attacks. These online attacks often result in lost revenue, identity theft and pubic relations nightmares for both small and large web-based companies.
A web vulnerability assessment is how businesses can identify problems in online configurations and software coding that put your network at risk of an attack. So-called “SQL Injection attacks” and others make it possible to gain access to your confidential information, including administrator and client log-ins and passwords.
Worst of all, your clients personal financial information could also be vulnerable (credit card numbers, addresses or even social security numbers), or an attacker could even alter your pricing information,resulting in huge losses of revenue
To be as certain as possible that your network security is adequate, the best option is to instigate a vulnerability assessment of your entire online infrastructure. This requires the use of vulnerability scanners and savvy experts who are up-to-date on current network attack exploits
Web vulnerability scanners can identify programming errors and oversights that create holes in your online infrastructure; these automated “bots”can crawl all of your online applications and perform assessments of many variables at once. A process like this could take a human team weeks or even months to complete.
Hiring an experienced network security consultant is the best way to conduct a vulnerability assessment. Basically, you need an experienced individual who will think in much the same way as the hackers. For this reason, many network security consultants are also known as “ethical hackers.”
To begin a vulnerability assessment, the security of your most crucial applications should come first. Identify your top priorities in your network and start there.
Once your assessment is completed, you will be provided with a list of vulnerabilities. These must again be prioritized according to value to your company and looked at one-by-one.
Ordinarily, at this point you will have some problems to fix. After prioritizing these issues, begin to manually check the most critical areas first. This is, of course, time consuming, but if you have prioritized well, you can be sure that the most critical issues receive your full attention right away.
The list of possible issues you could have is far too long to list here,and unfortunately, there are new threats emerging all the time. For this reason it is important to make your vulnerability assessments a regular part of normal business operations. Assessment is an on-going process, and staying up on the latest developments and exploits is critical in order to ensure continued network security.
In general, larger companies should have an assessment at least annually,if not more often. Smaller companies often opt for a 15-18 month check up,and this should serve well, as long as the company is not using a wide variety of network applications spread over several servers.
Vulnerability assessments are essential for any company with a web presence these days. Without learning where and how your web infrastructure is vulnerable, you are left to the mercy of an increasingly wide variety of online exploits and attacks. Scheduling regular network vulnerability assessments is the best way to ensure the security of your
network, and protect your company’s image, reputation and income.
