                       light weithted vul record


   Vulnerability information will be recorded in risk detection and
   scanning.  If a vulnerability is detected in a host during one scan,
   a record will be generated and added to the database, together with a
   time-stamp when the vulnerability is detected.  If risk detection is
   carried out periodically, a series of records will be generated for
   each detection, until vulnerability is fixed.  At present, a common
   way to record vulnerabilities is a vulnerability--a detection--a
   record, a vulnerability--N detections--N records(N>1).In this way,
   the number of vulnerability records is related to the rounds of
   detection.  In the case that the number of existing vulnerabilities
   remains unchanged, more frequent vulnerabilities are scanned, more
   records are recorded In this document, a light weighted vulnerability
   recording method is proposed.  To make that, in the whole life cycle
   of a vulnerability, only one record is generated after multiple

1.  Introduction

   In the process of risk management, large enterprises and institutions
   often use the method of periodic vulnerability detection and
   scanning.  At present, the common way to record vulnerabilities is to
   keep many records for each vulnerability.  Since the vulnerability
   state is time-dependent, each vulnerability record will carry time
   information to indicate the time stamp when the vulnerability is
   detected.  A vulnerability record usually contain the following

   1.IP address

   2.port: e.g. 23

   3.service: e.g. telnet

   4.protocol: TCP or UDP

   5.vul_name: e.g. telnet weak password

   6.vul_det_time: time stamp when the vulnerability is detected, e.g.
   2020-10-10 10:20:30

   7.vul_detail: additional information of vulnerability, in the
   scenario of weak password, vul_detail could be admin / 123456

   By using these data, security administrators can locate the
   vulnerabilities on specific hosts and specific services.

2.  Data Structure

   In the work of continuous security monitoring, if the same
   vulnerability of the same host is not repaired in time, multiple
   records will be generated.  And the more frequent periodic detection,
