Vulnerability Assessment

A vulnerability assessment is a process of identifying and prioritizing security weaknesses in an organization’s IT infrastructure. The goal of the assessment is to identify areas where the risk of compromise exists so that these can be addressed with appropriate countermeasures. Vulnerability assessments are typically performed by third parties on behalf of organizations, although some organizations perform them internally as part of a periodic review or audit.

The term “vulnerability” refers to any weakness in an asset (e.g., software, hardware, operating system, etc.) that could allow an attacker to gain unauthorized access. A vulnerability may exist because it has not been properly patched, improperly configured, poorly designed, or simply due to poor programming practices. For example, a buffer overflow flaw in a web application might allow attackers to inject malicious code into the vulnerable application. Such flaws often result from improper coding practices, such as failing to validate user input before using it.

Vulnerability Scanning and PCI DSS Compliance

The Payment Card Industry Data Security Standard (PCI DSS) is a set of standards for organizations that store, process or transmit credit card data. The PCI DSS was originally published in 2004 by the payment card industry’s trade association, the PCI Security Council. It was updated in 2011 and again in 2016. Organizations must comply with these standards to maintain an acceptable level of risk.

The most recent version of the PCI DSS requires that all companies performing a network scan conduct a vulnerability scan as well as a compliance assessment. This ensures that the organization is compliant before they begin working with clients.  

Benefits of Vulnerability Assessments

Vulnerability assessments are a great way to identify potential security risks and vulnerabilities in your organization. They’re also an excellent tool for improving the security posture of your network, as well as ensuring that you have all the right policies and procedures in place.

The benefits of vulnerability assessments are numerous.

First, they help ensure that your organization stays secure.

Second, they help keep your staff safe.

Third, they help reduce costs.

Fourth, they help improve efficiency.

Fifth, they help increase productivity.

Sixth, they help achieve compliance.

Finally, they help protect intellectual property.

Common types of vulnerability assessment

Vulnerability assessment is the process of identifying and prioritizing potential security weaknesses in a system or network. It can be used to identify vulnerabilities that may lead to compromises, such as weak passwords, default accounts, or unpatched software.

The most common method of performing vulnerability assessment is penetration testing. Penetration testing involves attempting to break into a computer system or network, usually without authorization. This type of testing may involve attempts to exploit known vulnerabilities, brute force attacks, or social engineering. In addition to finding known vulnerabilities, penetration tests can also help uncover new ones.

Penetration Testing

Penetration testing is the practice of trying to find security holes in a target system. These holes are called vulnerabilities, which are weaknesses in a system or its defenses. They are sometimes referred to as ‘backdoors’ since they give an intruder access to otherwise secure systems.

Penetration testing is a method of finding weaknesses in a target’s network infrastructure. It involves using various tools, techniques, and methods to find vulnerabilities in a network. Penetration testers use various techniques to try to discover these vulnerabilities. Some of these techniques include:

Social Engineering—This technique relies on human interaction. An attacker tries to trick a person into disclosing information about the system or network. Examples of this include phishing emails, pretexting phone calls, and other forms of deception.

Dumpster diving—Attackers search garbage bins for sensitive data.

Physical Access—The attacker gains physical access to the system or network being tested.

Wireless Hacking—Hackers attempt to intercept wireless signals to capture data.

Network Scanning—Attackers scan networks looking for open ports, hosts, services, and more.

Web Application Scanning—Attackers look for specific types of errors or vulnerabilities within web applications.

Network Scans

Network scans are a form of scanning that looks for open ports, hosts and services, and other items on a network. The purpose of a network scan is to determine what is running on a network and if there are any problems with the configuration. There are many different ways to perform a network scan, including port scans, ping sweeps, and vulnerability scans.

Port Scans

A port scan is a test performed by a hacker to see what computers are connected to a particular network. For example, if you wanted to know how many printers were connected to your company’s network, you could run a port scan against the IP address of your printer server. You’d then receive a list of all the computers that had a connection to that server.

Ping Sweeps

A ping sweep is similar to a port scan, except it sends out pings instead of TCP packets. When a host receives a message, it replies with its IP address. If the host does not reply, it means that no one else has received the request. Ping sweeps are used to check whether a host is up or down. They can also be used to see if a host has been assigned a new IP address.

Vulnerability Scans

A vulnerability scan is a type of penetration test where hackers attempt to identify security flaws in a computer system or network. Vulnerability scanners can be automated or manual. Manual vulnerability scanners require someone to manually enter a command line into the scanner. Automated vulnerability scanners will automatically execute commands based on a set of rules. Many vulnerability scanners are capable of identifying both known vulnerabilities and unknown vulnerabilities.
