How to do well in enterprise system vulnerability assessment

As an overall plan IT Administrators , Are you always paying attention to the server 、 Workstations and staff computers 、 Notebook system security ？ Are you always paying attention to the new security events and system vulnerability information on the Internet ? In daily work, I have been defending against network attacks and repairing system vulnerabilities , But I am worried about the security loopholes that appear at any time , This is because there is no effective and systematic way to find and repair vulnerabilities .

IT Administrators should keep abreast of the latest system dynamics , Find the focus of attention to system vulnerabilities , Complete safety management tasks in a timely and efficient manner .

What is vulnerability assessment

Vulnerability assessment , Or more accurately, vulnerability analysis , It is to identify according to the risks that security risks bring to your enterprise , The process of evaluation and classification , So that you can accurately handle security issues , Reduce risks in time . Vulnerability assessment is an active means for system security , You can find those vulnerabilities that are more likely to be exploited , In this way, the most serious loopholes can be quickly repaired , So as not to cause loss .

Why do you need a vulnerability assessment tool

According to the latest Forrester Global Security Survey ,“ In the past year , Yes 49% Of enterprises have suffered one or more attacks , And software vulnerability is the biggest factor causing these damages .” In recent years , System vulnerabilities are proliferating . Tens of thousands of security vulnerabilities are discovered every year , This highlights the importance of vulnerability assessment of enterprises .

The reality is cruel , No security team has the resources or time to manually address each vulnerability . Even if you intend to do so , We should also solve the most serious problems first . Because not all vulnerabilities pose the same threat to the enterprise . You need a vulnerability assessment tool that can provide the required vulnerability background information , Learn about possible and unexploited vulnerabilities , In this way, you can solve emergency vulnerabilities first .

How to evaluate security vulnerabilities

Most vulnerability assessment tools provide common indicators , Such as severity rating and general vulnerability scoring system (CVSS) Level to assess security vulnerabilities . however , We should really understand the risks brought by vulnerabilities , You need to master the following list based on these indicators ：

• Whether the vulnerability has been publicly disclosed
• How long has this vulnerability been latent in your terminal
• How easy is it to exploit this vulnerability
• Whether the manufacturer has released a patch for this vulnerability
• Whether you can extract meaningful processing from the scanned data
• If there is no patch , Do you have a temporary fix

therefore , It's not just scanning for vulnerabilities , We should also be able to conduct vulnerability assessment , Be able to master all the information in the above list .

Vulnerability assessment tools

Vulnerability Manager Plus The design principle of vulnerability management is ：“ Pinpoint , prioritizing , Fix vulnerability ”.

Vulnerability assessment steps

Eliminate blind spots

Eliminating blind spots is the key to effectively evaluate vulnerabilities . Automatically discover assets in active directories and workgroup assets . Once new assets are added to the network , Will be discovered .

Continuous monitoring

When performing a manual or scheduled vulnerability scan , You may not be able to take measures in time . Whenever a new device or software enters your network , Your enterprise will face new vulnerabilities . You need to continuously monitor and identify vulnerabilities . Use agent-based scanning , Every time 90 Check the terminal for new vulnerabilities every minute .

Vulnerability assessment dashboard

The vulnerability dashboard is IT Administrators provide a clear view , Let you focus on the most worrying place .

Vulnerability severity summary

Don't ignore the importance of severity level ; They are common vulnerability risk assessment criteria . Vulnerability severity summary helps you track the number of vulnerabilities at each severity level that need to be addressed , So as to better see how many key vulnerabilities remain .

Zero Day vulnerability

Security vulnerability assessment One of the most critical aspects of is how the vulnerability assessment tool effectively enables you to understand Zero Day vulnerabilities . Zero Day vulnerability is the easiest target for hackers , Because before suppliers can release patches to fix vulnerabilities , Zero Day vulnerability has been known to the public or exploited by the opposition , Therefore, it is crucial to ensure that they are not buried by trivia .Vulnerability Manager Plus And the zero day count chart provides you with a view of zero day vulnerabilities in the network , So you can recognize them immediately , And repair it or use alternative mitigation measures , While waiting for the patch from the server vendor .

Vulnerability time matrix

Speaking of vulnerability repair , Time is very important . In recent years , The time from vulnerability release to vulnerability exploitation code disclosure is greatly shortened . The longer you wait , The longer the network is attacked .

Critical vulnerabilities can often be exploited automatically without any user interaction , Therefore, these loopholes must be solved immediately , Important loopholes should be 30 Repair within days , Low level vulnerabilities should be 90 Repair within days .

High priority vulnerability

This is what you should focus on ! Manage the list of vulnerabilities that are on the verge of being exploited . The list considers various risk factors , For example, the difficulty of vulnerability exploitation , severity , Time and patch availability . This form can help you ensure that no key factors are missed in the vulnerability assessment process .

Bug repair

By automatically associating vulnerabilities with their patches , You can immediately deploy patches to priority vulnerabilities . A separate patch management module is also provided , Used to set the regular patch plan . For zero day vulnerabilities , Provides a temporary solution .
