Security Bulletins Explained

Security Bulletins Explained

Although security vulnerabilities are not something that a company is proud of for Companies around the world it is also important to inform their customers about security vulnerabilities. It is done in the form of a Security Bulletin. It is made available either to select customers or to the public depending on the scope of vulnerabilities. The fixes to these security vulnerabilities are provided in the form of a patch.

A patch is a small fix to an existing piece of software, usually used to fix bugs or security vulnerabilities. The process of handling all the patches of components within the company’s information system is called Patch Management. This process includes acquiring, testing and installing multiple patches on existing applications and software tools on a computer, enabling systems to stay updated on existing patches.

Security Bulletins play a big role in managing patches. Once vulnerabilities are made available, customers are responsible for assessing the impact of any actual or potential security vulnerability in the context of their environment. That is why every security bulletin patch has a rating that represents a possible impact if the patch is not applied. There are four severity ratings in general:

  1. Critical- These updates should be applied without delay.
  2. Important- These vulnerabilities can be exploited to steal data or to cause a denial of service attack
  3. Moderate- Vulnerabilities that are mitigated by default configurations, authentication requirements, etc.
  4. Low- Vulnerability that requires either extensive interaction.

A General Security Bulletin consists of the following information:

  1. Name: It provides a common name for communication. Sometimes it is the Common Vulnerabilities and Exposures (CVE) IDs
  2. About: General information about the nature of variabilities
  3. Vulnerability information: List of Vulnerabilities and Exposures (CVE)
  4. Affected software with versions: List of products which are affected with versions
  5. Remediation/fixes:  Steps to recreate the issue
  6. Workarounds and Mitigations: Some temporary fix if available
  7. Change History: Publication and patch information related to this bulletin

These pieces of information are very vital for someone who is managing patches for an organization. The stakes are very high since one missing patch can cost millions of dollars if that vulnerability is exploited. It is always wise to automate the whole process. 

InfraGuard helps organizations automate patch management in two ways:

  1. Show Security Bulletin information with an option to install from the dashboard
  2. Install patches based on categories with zero human intervention
