Overview

To provide this service, Xcellhost security experts simulate the tactics, techniques and procedures (TTPs) of real-world attackers targeting your high-risk cyber assets. Our deep knowledge of advanced persistent threat (APT) attacker behavior can help you:

Determine whether your critical data is actually at risk

Identify and mitigate complex security vulnerabilities before an attacker exploits them

Gain insight into attacker motivations and targets

Get quantitative results that help measure the risk associated with your critical assets

Identify and mitigate vulnerabilities and misconfigurations that could lead to future compromise

How It Works

INFORMATION GATHERING

In this stage we perform detailed reconnaissance about the application, its architecture, features and security controls. Certain inputs are also sought from the Devt. team.

PLANNING AND ANALYSIS

Based on the information collected we devise a full scale “Red Team” approach to mimic real time attacks. To minimise the impact we plan the attack, either on dummy environment or during times of lowest network activity (lowest traffic).

VULNERABILITY ASSESSMENT

In this stage, we run vulnerability scanners to look for possible vulnerabilities and common vulnerabilities related to the platform, APIs, technology framework etc.

PENETRATION TESTING

Here we run exploits on the application to evaluate its security. We use custom scripts, open source exploits and in-house tools to achieve high degree of penetration.

REPORTING

We generate concise and succinct reports of vulnerabilities discovered along with discussion on the nature of vulnerability, its impact, threat level and recommendation to remove the vulnerability.

DISCUSSION

Our technical experts discuss the report, along with bugs found, and their impact scenario with the development team of the client. Comprehensive discussions are carried out on how to remove vulnerabilities and harden the application.

Our Network Pentest Methodology

Xcellhost excels at operating under a structured, repeatable methodology. We stress this concept in every engagement to ensure our findings are reliable, reproduceable, and of excellent quality. As such, our vulnerability assessments can always be verified by your team, both before and after remediation. To get these results, we adhere to the following steps:

Network Scope

Effective communication with the client organization is emphasized here to create an operating environment comfortable to both parties. During this phase, we accomplish all of the following:

  • Outline which assets of the organization are open to be scanned and tested.
  • Discuss exclusions from the assessment, such as specific IP addresses or services
  • Confirm the official testing period and timezones, if relevant

Information Gathering

Xcellhost ’ pentester collect as much information as they can on the target, employing a myriad of OSINT (Open Source Intelligence) tools and techniques. The gathered data will help us to understand the operating conditions of the organization, which allows us to assess risk accurately as the engagement progresses. Targeted intelligence might include:

  • External network IP Addresses and Hosting Providers
  • Known credential leaks
  • Domains in use by the organization
  • Misconfigured web-servers and leaked data
  • Misconfigured web-servers and leaked data

Enumeration and Vulnerability Scanning

In this phase, we utilize a variety of automated tools and scripts among other methods of advanced information gathering. We also take the time to closely examine all possible attack vectors. In the next stage, this gathering and planning will be the basis for our exploitation attempts.

  • Enumerating subdomains and directories
  • Open ports or services
  • Checking possible misconfigurations against cloud services
  • Correlating publicly and proprietary vulnerabilities with applications on the network

Attack and Penetration

After careful preparation, focus turns to exploiting the discovered network vulnerabilities. Xcellhost engineers begin working to prove the existence of conceptual attack vectors while preserving the integrity of the network. At this point in the engagement, we begin the following tasks

  • Compromising sandboxes and test environments
  • Using breached credentials or brute force to access privileged information
  • Combining attack vectors to pivot across the network or escalate our position in it

One Protection Plan

Reporting is critical to the success of the assessment, as it provides the lasting documentation to share with management and vendors. Each report is customized to the specific scope of the assessment and risk based on the individual organization. The reports are intuitive to read, but thorough in the findings. In addition, each vulnerability includes a detailed remediation strategy. Some of the elements that you will find in our reports include:

  • An executive summary for strategic direction
  • A walkthrough of technical risks
  • Multiple options for vulnerability remediation
  • The potential impact of each vulnerability

Remediation Testing

As an additional service, Xcellhost Security Labs will revisit an assessment after an organization has had some time to patch vulnerabilities. We will retrace our steps from the engagement to ensure changes were implemented properly.

Our engineers will also search for new vulnerabilities associated with the updates, such as misconfigurations in the network or flaws in a new software implementation. At this point, we will update our previous assessment to reflect the new state of the system.

FREQUENTLY ASKED QUESTIONS

Network penetration testing aims to do what a bad actor would do — identify and exploit vulnerabilities in your networks, systems and network devices. Yet the network pen test sets out to find any opportunities for an attack before an unauthorized user does.

By identifying real-world opportunities to compromise systems and networks, the network pen tester can provide suggestions to better protect sensitive data and prevent take-over of systems for malicious/non-business purposes.

A network penetration test typically employs globally accepted approaches based on the Penetration Testing Execution Standard (PTES). This will include:

          * Intelligence Gathering — the discovery of all accessible systems and their respective services to obtain as much information as possible.
          * Threat Modeling — identifying vulnerabilities within systems via automated scans and deep-dive manual testing techniques.
          * Vulnerability Analysis — documenting and analyzing vulnerabilities to develop the plan of attack.
          * Exploitation — Actually carrying out the attempt to exploit
          * Reporting — Delivering, ranking, and prioritizing findings to generate an actionable report, complete with evidence, for the project stakeholders.

Some network pen testing can be done using automation, but for the best results, your testers will use all the same techniques — including manual efforts — to access your network that a highly motivated bad actor might use.

A network penetration test will help you gain valuable insight into the security posture of the in-scope assets and be able to fix them before hackers are able to cause serious damage by exploiting them.

The overall time it takes to complete a network penetration test depends on the size and complexity of the in-scope network(s). That said, most tests take anywhere from one week to four weeks, start to finish.

We get this question a lot and it’s not easy to answer until some level of scoping has been performed. Our scoping process is quick, online, and painless. But overall, the complexity of the network and its components will ultimately determine its cost. For example, when determining the work effort, we take into account things like the number of live IP addresses, etc.

We get this question a lot as well. Short answer: exploitation and post-exploitation. Vulnerability assessments do not involve exploitation while penetration testing goes well beyond a vulnerability assessment and into exploitation and post-exploitation phases.
