Security vulnerabilities can allow a remote user to gain access to your company’s confidential information or to gain access to your systems and use them for malicious purposes. These vulnerabilities can be found through many ways including web browsing, email and chat sessions. Web vulnerabilities are most commonly found in low-cost websites that lack updated security controls. Email and chat vulnerabilities are usually found when users share their passwords, usernames or contact information.
Many companies rely on IT staff to identify security vulnerabilities in enterprise-level systems and fix them before they become public. However, this is a very time-consuming process that does not always catch all potential weak spots. There are several alternative measures that you can take to reduce the number of potential weak spots in your applications including conducting manual testing and vulnerability scanning. Security testing, sometimes called manual vulnerability testing or pen testing, is the process of scanning an application or network to discover security vulnerabilities that an intruder could exploit. Penetration testing is typically performed by software programs or performed manually.
The primary benefit of penetration testing is that it allows an IT professional to quickly determine whether a security vulnerability in a particular program or application has been exploited. This allows the IT professional to determine if a program or software has been compromised. Pen Testing involves testing the security vulnerabilities of a network or application using either a worm virus or a coding error. Most penetration testing techniques use one of the following methods: The scanning technique involves searching through a network for vulnerable computers. Network scans can often identify hundreds of vulnerable systems.
The identification of security vulnerabilities involves the process of determining whether a particular application is using unauthenticated access to a server. A server is considered “unauthenticated” if it does not require a login or password in order to access the files or data on the server. Typically, the server security is tested using protocol attacks. Protocol attacks are executed on an HTTP server by testing the server’s response time and response quality.
Automated vulnerability assessment tests are a method used to identify security vulnerabilities. These automated vulnerability assessment scans to identify security vulnerabilities using a set of rules or specifications. Based on the security vulnerability identified, automated vulnerability tests analyze the issues and determine whether the issue poses a risk to a company or business. Some of the security vulnerabilities identified through automated vulnerability tests include application security, buffer overflows, cross-site scripting, DNS server culmination and SQL injection.
In network penetration testing, a consultant performs a scan on an actual network in order to identify security vulnerabilities. Network penetration testing includes a variety of tasks including detecting security holes, inspecting the code base, analyzing the traffic between the client and server, probing for security holes, and so forth. Usually, network penetration testing include performing a scan on the host machine and/or the client workstation to detect security flaws in the underlying software and configure the flaw accordingly. A network penetration testing include performing remote system access, file and program access, user management, service pack installation, and more.
Gray Box Security Vulnerability Testing refers to a type of vulnerability testing performed on legacy computer networks without using any software or binary. Gray box testing uses a collection of programs that perform attacks on security holes and determine if the holes are exploited. Gray box security testing tools include scanning agents, fuzzers, and/or HTTP servers and application servers. For every vulnerability, the software creates a fake system so that the attacks can be performed. Usually, these types of tools to identify and locate security vulnerabilities within a network that can lead to unauthorized access, system access and execution of arbitrary code, remote system modification, and data disclosure.
Open ports are those that can be opened from other networks. Generally, an open port is an unsecured or non-shared port that can be connected to by other hosts. In order to allow secure connectivity, it should be guarded and restricted so that only authorized users have access to it. Examples of such security systems include Intrusion Detection System (IDSS) and Network intrusion detection system (NICIDS). For every open port, there may be a corresponding scanned vulnerability.
