Vulnerability Assessment and Network Security
Dicar Networks

San Jose, CA 95112
THE DYNAMIC PROCESS OF NETWORK SECURITY
by Vlad Sharoiko
Network security is a dynamic process because of the new threats and vulnerabilities that are uncovered every day. Your software may be secure today, but the intense pace of upgrades will continue to create the openings for new issues to arise. According to statistics released by the CERT Coordination Center, more than 300 vulnerabilities are reported every month. The process of discovering them, determining the potential security risk, and recommending fixes is called a Vulnerability Assessment.
A Network Vulnerability Assessment can:
Identify any potential security breaches a hacker could exploit
Analyze discovered vulnerabilities existing in the network
Provide a detailed explanation of the recommended fix for each threat
Despite the fact that most security measures are put in place to protect a network from the malicious outside world, many intrusion attempts are now happening from inside the organization. With the proliferation of laptops and handhelds, the possibility of an internal intrusion has greatly increased. For this reason, a complete assessment should be done with scanners located inside and outside the network to determine if potential issues exist in either place.
In addition, the reports generated should be structured for 2 levels of review. The Executive Report should represent a high level overview of the number of vulnerabilities detected, while the IT Department should receive a highly detailed report containing descriptions of each vulnerability and explanations of the fixes recommended for each one.
The key features of a Vulnerability Assessment are:
Automated scanning of internal and external network devices
Scan schedules customized to times of least activity on the network
Full SSL support to scan SSLized services such as https, smtps, & imaps
Smart service recognition to detect services moved to non-standard ports
Non-destructive scanning to avoid interruption of normal network activity
Complete reporting designed for 2 levels of review
A Vulnerability Assessment should be performed on a monthly or quarterly basis, depending on network size and usage. New vulnerabilities are discovered every day, including ones that can provide back door access through desktops or laptops already connected to the network. Even a configuration change or faulty upgrade can introduce an opportunity for breach that was not available a week ago. Testing and review on a regular basis can help discover potential issues and reduce the possible damage that can be done to the network, and in turn, the productivity of
the organization.
The results of vulnerability assessment tools represent a snapshot of system security at a particular point in time. Although these systems usually don’t reliably detect an attack in progress, they can determine whether an attack is possible, and furthermore, provide information about what can be done to minimize the possibility of damage from an attack.
Many companies provide Vulnerability Assessments, but it is advisable to consult with multiple vendors prior to deciding who will be given access to the network. The key factor is whether you are comfortable with their experience level, and the type of reports that can be provided.
