A Repository of Widespread Penetration-Testing Weaknesses


Penetration testing is a crucial step in figuring out weaknesses in a corporation’s IT infrastructure. It’s a essential evaluation exercise for organizations to make use of when defending their environments towards cyberattacks. The SEI conducts cybersecurity assessments for organizations and designs and develops purposes that facilitate the gathering and automation of the reporting of findings recognized on assessments.

This submit introduces a penetration-testing findings repository that’s now publicly out there on GitHub. Findings discuss with the vulnerabilities and weaknesses recognized throughout a penetration-testing evaluation. The repository standardizes the language of findings and minimizes the effort and time for report writing. Furthermore, the standardized finding-name format assists in analyzing aggregated knowledge throughout a number of penetration-testing assessments.

This repository was created in response to the naming inconsistency of findings on penetration-testing assessments and to create a big assortment of standardized weaknesses for assessors to make use of. Assessors would title findings in another way on assessments. Some assessors would title a discovering after a cyberattack whereas others would title it after a course of. The penetration-testing findings repository focuses on naming a discovering after the vulnerability and weaknesses that have been recognized on an evaluation somewhat than cyberattacks or processes. To assist assessors find findings extra shortly throughout an evaluation, the repository makes use of an affinity-grouping method to categorize weaknesses, which will increase usability by sorting the findings right into a hierarchical three-tier construction. Furthermore, the findings repository contains assets to assist assessed organizations remediate the findings recognized on a penetration-testing evaluation.

A key step in securing organizational techniques is figuring out and understanding the particular vulnerabilities and weaknesses that exist in a corporation’s community. As soon as recognized, the vulnerabilities and weaknesses should be put into context and sure questions should be answered, as outlined within the weblog submit Tips on how to Get the Most Out of Penetration Testing:

  • Which vulnerabilities and weaknesses do you have to spend finite assets addressing?
  • Which vulnerabilities and weaknesses are simply exploitable, and which aren’t?
  • Which vulnerabilities and weaknesses put vital belongings in danger?
  • Which vulnerabilities and weaknesses should be addressed first?

With out this context, a corporation would possibly dedicate assets to addressing the fallacious vulnerabilities and weaknesses, leaving itself uncovered elsewhere. The repository supplies a default finding-severity degree to assist an assessed group prioritize which findings to remediate first. An assessor can alter the default severity degree of the findings relying on the opposite safety controls in place in a corporation’s setting.

Repository Overview

The penetration-testing findings repository is a set of Energetic Listing, phishing, mobile-technology, system, service, web-application, and wireless-technology weaknesses that could be found throughout a penetration take a look at. The repository incorporates default names, descriptions, suggestions for remediation, references, mappings to numerous frameworks, and severity ranges for every discovering. This repository and its construction serve 4 main functions:

  • standardization—The repository standardizes the reporting course of by offering outlined findings for an assessor to pick from throughout an evaluation.
  • streamlined reporting—Offering pre-populated attributes (discovering title, description, remediation, assets, and severity degree) saves important time throughout the reporting course of, permitting assessors to deal with operations.
  • comprehensiveness—The repository’s layered construction offers assessors flexibility in how they current their findings because the vulnerability panorama evolves. When attainable, assessors choose a selected discovering. If no particular discovering precisely describes what was found, assessors can choose a normal discovering and tailor it accordingly.
  • ease of navigation—To make the repository simpler to navigate, it makes use of a tiered classification construction. Findings are grouped by the findings classes, permitting assessors to report on each normal and particular findings when creating studies.

As talked about above, the findings repository is a hierarchical construction containing the next three tiers:

  • Discovering Class Tier—lists the overarching classes: Energetic Listing Weak spot, Phishing Weak spot, Cell Expertise Weak spot, System or Service Weak spot, Internet Utility Weak spot, Wi-fi Expertise Weak spot.
  • Normal Discovering Tier—lists 27 high-level findings which are like subcategories of the overarching Discovering Class. Normal Findings can be utilized as a person discovering on an evaluation when there isn’t an appropriate Particular Discovering.
  • Particular Discovering Tier—lists 111 low-level findings that pinpoint a definite weak point that may be exploited throughout an evaluation. The precise findings include frequent findings ceaselessly recognized throughout assessments.

As proven within the desk under, there are six Discovering Classes:











Discovering Classes

Class

Description

Energetic Listing Weak spot

Energetic Listing (AD) is configured improperly. Some misconfigurations embody pointless service accounts and permissions, insecure encryption ciphers, weak password insurance policies, and/or insecure consumer or pc accounts. Attackers have numerous strategies of pursuing AD weaknesses, together with Kerberoasting, Golden Ticket assaults, Cross the Hash, or Cross the Ticket, which may result in a complete takeover of the infrastructure.

Phishing Weak spot

A phishing weak point permits an attacker to ship a weaponized e-mail via the community border that executes on the native host when a consumer performs an motion. These emails can comprise a number of luring attachments, Uniform Useful resource Locators (URLs), scripts, and macros. Insufficient protections enable malicious payloads to be executed.

Cell Expertise Weak spot

Cell applied sciences are more and more used to ship providers and knowledge. The quantity of information saved on cell gadgets makes their purposes targets for assault. In comparison with conventional computer systems, the performance on cell gadgets is harder to manage, and cell gadgets help extra advanced interfaces (e.g., mobile, Wi-Fi, Bluetooth, World Positioning System [GPS]), that expose extra surfaces to assault. Insecure cell expertise has vulnerabilities that attackers can exploit to achieve entry to delicate info and assets.

System or Service Weak spot

Weaknesses inside a system or service can lead to lacking vital safety controls that go away the group weak to assaults. These weaknesses can embody weak configuration steering that insecurely configures techniques and providers all through the group, inadequate or lacking configuration administration that leads to advert hoc or default configurations, and many others.

Internet Utility Weak spot

The safety of internet sites, net purposes, and net providers (e.g., software programming interfaces [APIs]) is known as net software safety. Internet purposes may be attacked by exploiting vulnerabilities on the software layer, transport layer, and software program provide chain. Internet software weaknesses are usually vulnerabilities, system flaws, or misconfigurations in a web-based software. Attackers typically exploit these weaknesses to both manipulate supply code or achieve unauthorized entry to info or features. Attackers might be able to discover vulnerabilities even in a reasonably sturdy safety setting.

Wi-fi Expertise Weak spot

Wi-fi applied sciences enable cell gadgets (e.g., laptops, good telephones, Web of Issues [IoT] gadgets, and printers) to connect with the enterprise community. Wi-fi networks can introduce potential vulnerabilities to a corporation via weak insurance policies that enable insecure wi-fi expertise (e.g., insecure gadgets, insecure configurations, weak authentication processes, insecure encryption) on the community.

The repository additionally maps every discovering to the three following frameworks:

Future Work

The plan is to replace the repository as new frequent vulnerabilities and weaknesses are recognized. Because the repository is open supply, nonetheless, the cybersecurity group can entry the repository and add to it.

Along with the Penetration Testing Findings Repository, a repository of frequent dangers that may be recognized throughout high-value asset (HVA) assessments is within the works. The aim of this repository is to standardize the language amongst dangers reported by assessors, in flip minimizing effort and time for report writing on assessments. Just like the penetration-testing repository, this new repository will comprise threat statements, descriptions, and suggestions for mitigation of dangers recognized on HVA assessments.
